3 Benefits of Hydraulic Pump Diagnostics

Mon, 18 Dec 2023 20:15:49 GMT

Hydraulic pumps offer essential needs for many industries. If you have a hydraulic pump that is not performing as it should, then the first step to consider is a pump diagnostic. A professional hydraulic pump rebuilding company can run a detailed diagnostic on your pump to determine different performance levels.

The diagnostic report will offer a lot of insight into what exactly is wrong with a hydraulic pump and the steps needed to get the pump running just as good or even better than it originally operated. Learn some of the benefits of hydraulic pump diagnostics and why that should be your first step if you run into any pump issues.

1. Spec Performance Versus Actual Performance

When you first purchase a hydraulic pump, it will likely come with a spec sheet that details the performance of the pump and the way it operates. A diagnostic test will see if the pump actually reaches those levels and where it falls short at. By comparing the diagnostic test to the original specs, repair specialists will have a good idea of how well the pump is running.

If the pump performs poorly in one area but fine in another area, then they can pinpoint some of the issues and know where to start with repairs and adjustments.

2. Specific Part Replacements

When a hydraulic pump stops working correctly, then you may consider just purchasing a whole new pump, but that could end up costing a lot more than repairs. With diagnostic testing, you will know which parts are not working on the pump and can simply replace the parts instead of replacing the whole pump.

The part replacement will come a lot cheaper and allow you to keep the same pump. For example, the problem could occur with a small part inside the pump like a seal or bushing. These parts are relatively easy to replace and will cost much cheaper than a whole new pump.

When you work with a hydraulic pump rebuilding company, they will often have these parts on hand as well. This can speed up the process from the diagnostic testing all the way to the repaired pump that is ready to go in whatever application you need it for.

Once you establish yourself with a repair company, you can cycle out hydraulic pups as needed and do not need to constantly raise your budget with new pump orders.

3. Professional Repairs

Not only do hydraulic pump repairs help fix current issues, but the diagnostic testing and repair process can expand the life of your pump. Simple repairs can ensure pumps last for years longer without any cracks or degrading that leads to major issues.

For example, if you repair the seals on a pump, then you will prevent a pump from overheating, leaking, or damaging other parts of the pump. The professional repair process will keep the pumps going strong for years to come.

In some cases, the diagnostic testing will help catch problems you didn't know you had. For example, the diagnostics could show that an idler gear is worn down and not performing as fast as it should. With professional repairs, your pump can have a new gear installed and prevent the pump from malfunctioning in the future.

Reach out to us at Quad Fluid Dynamics, Inc. , for all of your hydraulic pump needs. Along with diagnostic repairs, we offer full repairs and rebuilds of your hydraulic pumps. Our full warehouse of parts will ensure your repairs get done in a timely manner. After the repair is completed, we will run another diagnostic test to ensure your pump operates like it should.

Common Causes of Hydraulic Pump Failures

Thu, 07 Dec 2023 13:26:20 GMT

Hydraulic pumps are the heart of many industrial systems, powering everything from construction machinery to manufacturing equipment. When they work, they're great, but when they fail, this can cause big problems. Understanding why hydraulic pumps fail is key to preventing downtime and costly repairs. Dive into the common causes of hydraulic pump failures and explore effective solutions to keep your systems running smoothly.

Contamination: The Silent Pump Killer

Tiny particles that shouldn't be there can get inside and cause a lot of damage. These particles can come from various sources, like dirty oil or a contaminated environment. They can wear down the pump's parts, leading to leaks or total failure.

The solution? Keep things clean. Regularly changing the hydraulic oil and filters can go a long way. Also, make sure your environment is as clean as possible to prevent external contamination.

Overheating: When Things Get Too Hot

Overheating usually happens when the oil temperature gets too high, which can damage the pump. Overheating can be caused by a few things, like using the wrong type of oil, a clogged filter, or a system running too hard for too long.

To fix this, check the oil type and make sure it's right for your pump. Regularly check and clean the filters, and give your system a break now and then to cool down.

Aeration and Cavitation: Bubbles and Voids

Aeration happens when air gets into the hydraulic fluid, while cavitation occurs when there are voids or cavities in the fluid. Both can cause serious damage to the pump. Aeration can make the oil foamy, which reduces its effectiveness. Cavitation can happen when the fluid's pressure drops too low and it starts to vaporize.

To prevent these issues, check for leaks and fix them fast. Also, keep an eye on the fluid levels, and make sure the pump is properly primed to avoid introducing air into the system.

Improper Sizing or Installation: A Bad Fit

Sometimes, the problem starts right at the beginning. If a pump is the wrong size for the system or if it's not installed correctly, it won't work right. A pump that's too small won't be able to handle the load, while one that's too big can cause excess wear and tear.

Make sure you get the right size pump for your needs. If you're not sure, consult with a professional. Also, follow the manufacturer's guidelines for installation to ensure everything is set up correctly.

Wear and Tear: The Inevitable Aging

Like anything else, hydraulic pumps can wear out over time. This is a normal part of their lifespan but can lead to failures if not managed. Regular wear can cause parts to degrade, leading to decreased performance and eventually failure.

The best solution here is regular maintenance. Regular check-ups can catch problems early, and replacing worn parts can keep your pump running smoothly.

Mismatched Components: The Pitfalls of Incompatibility

Hydraulic systems are complex, and each part needs to work in harmony with the others. If components like valves, hoses, or fittings are not compatible with the pump or with each other, this can lead to increased stress on the pump. This stress can cause premature wear and tear or even complete failure.

The key to avoiding this is ensuring that all components of your hydraulic system are matched and compatible. This might mean checking the specifications of each part carefully and consulting with experts when replacing or upgrading any component. Proper compatibility not only extends the life of the pump but also ensures the efficiency and reliability of the entire hydraulic system.

If you're facing hydraulic pump troubles or want to prevent them before they start, reach out to Quad Fluid Dynamics, Inc. , for assistance.

A Quick Guide To Ordering Hydrualic Pump Parts

Fri, 27 Oct 2023 18:47:14 GMT

When a hydraulic pump breaks down or malfunctions, you probably do not want your work to be impacted for a long time. Hydraulic pump repair includes many steps, but after diagnosing the issue, the next step is determining exactly what parts you need. Over the years, there have been thousands of different hydraulic pumps produced by companies.

Unfortunately, there are rarely any universal parts that can expand across multiple pumps. Follow this quick guide to learn some of the best methods for determining exactly what part you need and how to access those parts quickly.

Identify the Part Number

Hydraulic parts often have identifying information right on the part to determine the exact part number. A part number may include just numerical digits. Others may include a mix of numerical and alphabetical digits. Others may include dashes between the digits, which is an important element of a part name.

For example, you could have a part with the name 18JP90-4567. If you search for the part without the dash, then you could run into issues finding the proper part. Look for a metal part tag that has been fused directly to the hydraulic pump. In some cases, the tag may read PN for part number or directly state Part Number.

The tag may also feature the model number, which could also help narrow down your search and allow you to find the pump part you need more easily. With this information, you can order new parts and have confidence that you have select the exact part you need.

Alternate Identification Options

In some cases, you may not have the part information available on the tag. The tag could have fallen off or the information could have worn off through the years. First, check company records to see the purchase history of specific pumps and parts. This could help you match up with the exact part you need.

You could also do an image search to identify the part you need. Many phones have the capabilities to complete image searches through apps. Take pictures from multiple angles, and see what results come up from image searches. Through those searches, you can find more details on what parts you need.

If the online image searches do not help, then reach out to hydraulic repair companies to help with your search. Repair specialists have years of experience handling all kinds of different pumps and can help you identify exactly what part you need.

Purchase Directly From a Parts Warehouse

When you work with a repair company, look for a company that has their own warehouse of parts and supplies. With a warehouse right on their property, you can shorten the amount of downtime you have as you wait for the pump to get repaired. A vast warehouse of parts means they will likely have your part in stock.

You will not need to wait for the part to come in, and the repair process will begin a lot faster. Even if you find parts to order online, check with the repair company first and see what they have in-stock. The process can help cut down a lot of time and allow you to get the pump up and running again as quickly as possible.

How to Drain and Clean Your Hydraulic Pump's Reservoir

Thu, 28 Sep 2023 15:59:55 GMT

Like any other machinery, hydraulic pumps need routine servicing to function efficiently and last longer. An essential factor of this maintenance practice is to empty and clean the hydraulic pump's reservoir.

Fear not if you're uncertain about the correct procedures or have been putting off this task. This article will guide you through the step-by-step process of draining and cleaning your hydraulic pump's reservoir.

Drain the System

To drain the system, empty the liquid from the reservoir, the pipes, the valves, the accumulators, the filter housings, and wherever else it may have accumulated.

Clean the Reservoir

Remove dust or dirt from the reservoir's exterior with a clean, dry lint-free cloth. Next, use a clean rag to wipe out the inside of the reservoir, paying special attention to any areas where paint, sludge, or deposits have become mushy or loose. Also, inspect the reservoir's internal cavities, clearing them of pitting and any buildup of sludge or deposits.

Flush With Specialized Fluid

First, fill the tank with a flushing substance whose viscosity is close to or lower than that of the machine's operating fluid. Stroking the valves repeatedly will help move the cleansing fluid through the system more effectively.

The reservoir can be emptied after the flushing fluid has passed through the system. To avoid a backlog of forward contamination, you should do this as fast as possible at a high temperature. After you have emptied the fluid, inspect the reservoir for debris and sterilize it if necessary.

Bleed the Pump

Load the system with the hydraulic fluid until it is about 75 percent full. Then, either activate the pressure relief valve or turn on the pressure pump. The next step is to operate the pump for 15 seconds and then deactivate it for 45 seconds at regular intervals.

To get the pump going, you need to do this three times. After that, you need to run the pump nonstop for a few hours to get all of the old fluid out of the system and the fresh fluid in, which will get the pump cycling again.

Test the System's Integrity

Power down the hydraulic system and allow the fluid to flow generally by opening the bypass mechanism or pressure relief valve. Operate the system with the pressure release or bypass valve open for one minute, and then allow the system to cool down.

Do not leave the pump under load for more than five minutes after closing the bypass. Raise the relief valve during this time to flush it out. The next step is to turn off the pump and wait at least five minutes before continuing. It is important to give the system some downtime in between each time you run the pump and inspect the relief valve.

Activate the Pump

Ensure the hydraulic system's tank is at least a quarter full before turning on the pump. Activating the pump will trigger fluid to move from the reservoir into the actuator lines. Then trigger each actuator manually.

Let the fluid drain back into the reservoir between actuator uses is necessary. Keep going until you have activated every single actuator. When done, turn off the machine. Maintain a fluid quantity level of at least half capacity by checking it frequently and topping it off as needed.

Refill the Reservoir

Depending on how the system is set up, fill the reservoir to about 75 percent. After filling the reservoir, operate the system for five minutes, letting air out during each shutdown. Listen for cavitation and other strange noises as the system operates. Additionally, the operator should monitor the reservoir for any evidence of cross-contamination during this time. Cross-contamination indicators necessitate filter replacement and further testing.

Evaluate for Stability

After maintenance, the system should be tested to ensure it functions well before being returned to service. You must run the reservoir for six hours to ensure the system is stable and replace the filters. This time frame is adequate for verifying fundamental performance and reducing danger in the event of unforeseen problems.

Copy of An Overview of Hydraulic Motor Types

Mon, 04 Sep 2023 04:28:30 GMT

In the realm of hydraulic systems, the choice between an open loop and a closed loop configuration marks a fundamental decision that shapes the efficiency, functionality, and performance of various mechanical applications.

Understanding the distinctions between these two hydraulic system types is pivotal to making informed decisions when selecting the most suitable hydraulic setup for your specific needs. Let's delve into the world of hydraulic circuits, exploring the differences, advantages, and applications of open loop and closed loop configurations.

Open Loop System

In open loop hydraulic systems, the hydraulic pump, its motor, and actuator's input and return connections all lead back to the same reservoir of hydraulic fluid. The fluid circulates between the reservoir and the actuator. A relief valve or other pressure-regulating control valve directs the flow to the actuator before the used fluid is recycled back into the storage container.

An open loop hydraulic circuit's primary benefit is its low price. It's more efficient and cost-effective than alternatives that necessitate a closed circuit but would require more complex equipment and more power. Because of the reduced number of parts, open loop circuits are also easier to service and analyze.

However, open loop hydraulic circuits are less efficient than closed-loop ones. Since the fluid does not circulate in a closed loop, it may take a while to refill the reservoir, which may result in inefficient heat production and a decrease in efficiency. The volume of the reservoir also needs to be adequate for sufficient cooling.

Heavy machinery commonly uses open loop hydraulic systems because of their simplicity and low cost. Systems that run at lower pressures, including turbines, heat exchangers, and cranes, benefit the most from open loop control systems.

Closed Loop System

Mobile applications that require a lot of power under high pressure, such as skid steers and refrigerators, use closed loop hydraulic circuits. These systems eliminate the need for a storage tank altogether by routing fluid straight from the pump to the motor before returning to the pump via a series of valves, filters, and accumulators. This design decreases the system's overall complexity, cost, and mass.

The primary pump in closed-loop systems is typically a fixed-displacement pump with a capacity of only about 15% of that of an open-loop system's primary pump. In addition to the lower oil reservoir, this contributes to the system's reduced size and cost.

Precise motion control uses, such as those required in mobile equipment and machinery and automated manufacturing processes, are ideally suited to closed loop circuits. Closed loop systems are self-sustaining and can be utilized in more compact configurations than open loop systems because they eliminate the need for external control devices like valves to regulate fluid flow.

In a closed-loop hydraulic system, the applied pressure of the hydraulic fluid (often hydraulic oil) drives the motor. The main pump regulates the entire system's fluid pressure and flow and can change the motor's rotational direction by directing fluid via one of the two ports.

Closed loop hydraulic systems are challenging to evaluate and expensive to repair because of their reliance on precise control. These systems also require hydraulic fluid filtration at elevated pressures to protect the motor and other parts from contamination.

Bottom Line

The ideal circuit for a hydraulic system varies based on the system's design and intended purposes. Closed loop systems are suitable for wheel and track drive motors on moveable machines and mobile equipment because of their lightweight and precision. In contrast, open loop systems are ideal for systems that rely on cylinders or rotators due to their durability.

An Overview of Hydraulic Motor Types

Fri, 11 Aug 2023 10:37:34 GMT

Hydraulic motors are an integral part of complex systems, and play a critical role in many mechanical systems. Here is a guide to their different types to help you understand how they work.

Gear Motors

Gear hydraulic motors feature an idler gear and a driving gear connected to the output shaft. An inlet port allows high-pressure oil to flow into the motor from one side, circling between the outside edges of both gears and the motor housing. The gears mesh so closely so that the oil does not leak back into the inlet.

Because of their symmetrical internal construction, balanced exterior, and similarly sized inlet and output ports, these motors can operate in either a negative or positive direction. They incorporate more teeth than the pump to minimize torque ripple and use rolling bearings to lessen frictional torque at startup.

Gear hydraulics motors have a low inertia, are resistant to impact, have a good suction capacity, and are easy to maintain. However, they come with a high noise level and instability at slower speeds, a low beginning torque, and a huge pressure and torque fluctuation.

The gears' constant rubbing against the motor's housing and primary bushings progressively reduces its volumetric efficiency. This typically occurs just before the device seizes up or stops working altogether.

Vane Motors

Vane hydraulic motors are rotary actuators that utilize pressurized fluid to rotate a rotor fitted with vanes that may be moved into and out of the motor's enclosure. Because of the resulting imbalanced force, the rotor can only spin in one direction. A perfectly milled lip between the motor casing and the vane prevents dust and debris from getting inside, and creates a tight seal that reduces wear and metal-on-metal contact.

The advantages of vane hydraulic motors are their compact design, uniform flow, minimal moment of inertia, quiet operation, and a high degree of adaptability. They can manage a lot of switching and give you responsive, precise action.

However, vane motors suffer from high leakages at low input pressure and instabilities at low speeds. When compared to gear motors, they also offer weaker pollution control features.

Axial-Piston Motors

The axial-piston motor is used in equipment and activities that require dynamic motion. To generate torque or rotational power, these motors rely on a piston that moves axially as it is propelled by pressurized oil. A swash plate inside the cylinder acts as a path for the piston, and the oil is pushed into the cylinder via an opening in an oil distribution panel.

The swash plate's reactive push—consisting of an axial force and a vertical force—counters the pressure oil, allowing the piston to generate torque against the cylinder's core. The flow direction of the pressure oil feeding into the motor determines whether this torque is translated into positive or negative rotation power, which impacts which way the motor shaft spins.

The benefits of axial-piston motors are high weight-to-power ratios, fast rotating speeds, and the ability to function in high-pressure environments.

Radial Piston Motors

A radial piston motor uses compressed hydraulic fluid to generate mechanical rotational energy. This motor's traditional design features a stationary core called the directional valve that holds two channels for fluid inflow and delivery.

The valve rotor contains multiple radial bores that house free-moving pistons. Pistons travel in opposite directions within these bores, with tension from the stator facilitating rotation of the rotor and pistons. This causes the motor's output shaft to spin and release kinetic energy.

Although radial-piston motors supply only moderate torque, they can rotate at high speeds thanks to the smaller amount of hydraulic fluid required by each piston. In addition, the motor's eccentricity can be changed to provide different speeds and reversibility for a given flow rate.

A Guide to Hydraulic Fluid Types, Properties, and Uses

Mon, 10 Jul 2023 04:06:14 GMT

Hydraulic systems provide power and control to numerous mechanical and industrial processes with astonishing efficiency. At the heart of these systems lies hydraulic fluid, a critical component that enables the transmission of force and motion. Understanding the different types, properties, and uses of hydraulic fluids can help ensure optimal performance, reliability, and longevity of hydraulic systems. Let's look at hydraulic fluid types, properties, and uses.

Petroleum-Based Hydraulic Fluid

Petroleum-based (mineral-based) hydraulic oils are one form of hydraulic fluid produced from crude oil and refined petroleum. The lubricity, demulsibility, viscosity index, durability against oxidation, and rust resistance of lubricants derived from petroleum are all superior. With the correct additives, petroleum-based fluids also work well with numerous seal materials.

Many hydraulic pump operators prefer petroleum-based fluids because they are inexpensive. With regular upkeep, they can function admirably in a wide range of hydraulic systems, as long as their working temperature is below 50 °C .

One major drawback is that these fluids can catch fire. Thus, they are commonly used for industrial and mobile machines with minimal danger of flames. Because of their wide availability, these fluids are the most popular hydraulic fluids. With high-quality additives, they can even act as an alternative to synthetic fluids.

Synthetic Fluids

Synthetic hydraulic fluid constitutes an artificial chemical substance that excels at lubrication, stability, and efficiency in extreme conditions. Synthetic fluids can operate with minimal issues in high and low temperatures and high pressure. The necessary properties of these fluids occur by assembling a specific sequence of molecules in a liquid base oil.

Synthetic hydraulic fluids have a substantial viscosity index. They retain their viscosity better than conventional fluids across a broad temperature range. The fluid's functionality is more stable because of the increased viscosity. Thus, the high viscosity negates any potential damage from fluctuations in temperature.

Compared to conventional fluids, synthetic fluids have far higher oxidation resistance, which makes them more resistant to breakdown from high temperatures. They are less prone to fail under high pressure because of the higher shear stability.

Despite the many upsides, numerous hydraulic pump operators may be put off from using synthetic fluid in their hydraulic systems due to its cost. The initial investment required to move to a synthetic system is high because of the high cost of these fluids.

Also, numerous synthetic fluids are hazardous and could harm anyone who comes into contact with them. These fluids' chemicals may also be incompatible with certain seal materials, necessitating the usage of more costly seal and gasket components.

Water-Based Fluids

Water-oil emulsion and water glycols are the two most prevalent water-based hydraulic fluids. The cheapest option is a water-oil emulsion, which consists of water and oil. Water glycols comprise water, glycol, and additives like viscosity improvers and rust regulators.

Water-based fluids are commonly applied in hydraulic equipment in the aerospace and manufacturing sectors. These fluids are less susceptible to fire since they consist of a mixture of water and oil.

Water-based hydraulic oils have numerous benefits. These fluids may be utilized with the same equipment as those that run on petroleum-based lubricants due to their fire resistance.

However, water-based hydraulic fluids have a few drawbacks. To avoid evaporation and oxidation, the working temperature of these fluids must remain below 50°C (122°F). In the case of water-oil emulsions, they are also susceptible to phase separation. In addition, pump operators must consistently monitor the oil-water ratio to account for water loss caused by evaporation.

Hydraulic Equipment Repair Vs. Rebuild: Understanding The Differences

Wed, 10 May 2023 16:22:48 GMT

Loud and strange sounds, leaky seals, hot-to-touch equipment, and overpressuring are all signs that your hydraulic equipment is failing. And in that a case, you cannot afford to waste time before you solve the underlying issues and restore your equipment to its prime efficiency.

But how do you decide when to rebuild or repair your hydraulic system? This blog explains the differences between the two restoration methods and when each is the most recommendable.

What Is Hydraulic Cylinder Repair?

Hydraulic cylinder repair is the process of replacing a few components in the system to restore its efficiency. During this repair, technicians will replace seals, hoses, and other components that can be easily removed from the machine.

For example, suppose the inside of your hydraulic system has scratches. In such a case, a technician can hone the barrel until the inside feels smooth. The professional can do this by removing the inside material of the barrel.

Consequently, the inside cylinder's dimension will become bigger, meaning the piston can no longer fit. In that case, you will need new pistons to suit the new dimensions. From this, it is clear that repair focuses only on the immediate problem while leaving the rest of the cylinder untouched.

What Is Hydraulic Cylinder Rebuild?

As the name suggests, hydraulic cylinder rebuild is disassembling the entire cylinder, refurbishing its components, and reassembling it. In this case, technicians will use new, Original Equipment Manufacturer (OEM) approved parts to create a cylinder that works just as it did when it first shipped from the factory or even an upgraded one that works better.

The professionals will inspect each part of the cylinder for damage and wear before deciding which parts must be replaced or refinished. After reassembling, the cylinder undergoes comprehensive testing, and in case of any quality and performance issues, the problems are rectified before you can use it again.

Which One Is Better; Rebuilding or Repairing?

There is no one-size-fits-all answer to this question; it all depends on the condition of your cylinder and your needs and budget. Here are some factors to consider to help you establish the right choice for your machine.

The Lifespan of Your Machine

If your cylinder is still new, with small issues leading to its failure, a repair is the most appropriate option. But if your cylinder is older, with frequent breakdowns and deteriorating performance, it would be best to go for a rebuild.

Your Budget

Repair is the most cost-effective and timely option if you are looking for a quick fix. However, rebuilding will be the best choice if you want to restore your cylinder's performance to its original level.

Note that although the initial cost of repairs may seem more favorable, the long-term repair cost can be higher than a rebuild. It will just be a matter of time before the repaired parts break down, and you must repeat the process.

Consider Parts Quality

One drawback of repairing is that the parts used are not necessarily the same quality as OEM parts. There may be inconsistencies in the materials' quality, which can lead to further problems.

Rebuilding, on the other hand, uses only OEM-approved parts that are tailored to fit your machine's original specifications and dimensions. As such, you get quality assurance and a performance guarantee for an extended period.

Benefits of Using CNC Machines for Your Manufacturing Business

Thu, 27 Apr 2023 18:20:10 GMT

CNC machines are becoming more popular in manufacturing because they have many benefits. CNC machines have changed the way things are made. Read on to learn why using CNC machines is good for your manufacturing business.

High Precision

The use of computer software enables precise control over the movement of cutting tools and ensures that each cut is made where it needs to be. This software eliminates human error and lowers the risk of manufacturing mistakes. Because CNC machines are so accurate, they can also make complicated shapes and designs that would be hard or impossible to make by hand.

Speed

CNC machines are made to work nonstop, which speeds up production and makes more things possible. Once a CNC machine is programmed, it can operate 24/7, producing parts quickly. This speed allows manufacturing businesses to create more pieces in less time, which leads to increased revenue and profitability.

With traditional manual machines, the time needed to change and set up the machine for different parts can be significant, leading to delays, reduced productivity, and increased costs. On the other hand, CNC machines are easy and quick to re-program, so businesses can switch between parts and products with little downtime.

Safe and Easy To Use

Quality control features like sensors and cameras are added to CNC machines to improve the quality control process. These features find inconsistencies or mistakes in the parts made and tell the operator immediately. This lets the operator make quick changes and reduces waste. Also, machine operators do not need to get close to the cutting tools, which helps prevent accidents in the workplace.

Low Energy Consumption

CNC machines use less power, which makes them a good choice for manufacturing businesses. This low energy consumption means the business's energy bills and carbon footprint will decrease, which makes CNC machines a good choice for the environment.

CNC machines also have advanced technology that keeps track of and controls how much power the machine uses. This technology helps reduce energy use and lowers operating costs. CNC machining is especially beneficial to industries such as automotive, oil and gas, aerospace, and others that use a lot of energy.

Future-Proofing Your Company

CNC machines help businesses stay competitive by shortening turnaround times, lowering costs, and letting them make more things. As manufacturing evolves and becomes more technologically driven, the use of CNC machines can help businesses stay relevant and competitive in the future.

Reduced Manual Labor

CNC machining necessitates fewer people to complete production tasks. One skilled operator can run several CNC machines that work independently, and one programmer can load them with the designs they need. For a manual machine to work, it needs at least one experienced operator per machine and a group leader. Also, you can pass on the savings from reduced labor costs to your customers, giving your business a competitive advantage.

Cost-Effective

CNC machines cost a lot of money upfront, but they last longer, make more parts, and make fewer mistakes in the parts they make. These machines need less repair and maintenance. CNC machines can mill, drill, cut, and grind. Because of this versatility, businesses can produce a wide range of parts on a single machine, which reduces the need for multiple machines and operators.

The high precision reduces manufacturing errors and eliminates unnecessary waste. Also, because a skilled operator can run multiple machines simultaneously, this machining requires fewer machine operators, saving you resources in the long run.

Investing in CNC machines is a great way to improve the efficiency and profitability of your manufacturing business.

Common Types Of Hydraulic Pumps You Should Know

Wed, 01 Feb 2023 08:57:19 GMT

The pump is an integral part of any hydraulic system that receives mechanical energy and transforms it into fluid energy. This process takes place inside the hydraulic system. The mechanical energy comes from the "prime mover," which could be the power take-off or the engine of the truck.

Hydraulic pumps are available in various configurations and find applications in many fields of industry. Each hydraulic pump will have either a single-rotational or a double-rotational design. But each type has a distinct internal structure based on the same fundamental concepts.

Learn more about the most common hydraulic pumps and some of their distinctive features.

Screw Pumps

In a screw pump, the long shaft has helical grooves carved into it at regular intervals. One end of the shaft has a rod connected to it that rotates. When an engine or motor spins the shaft, the hydraulic fluid flows into the grooves. Then, centrifugal forces propel the fluid upwards.

Gear Pumps

A gear pump is a device that uses gears to transmit mechanical and fluid energy from one shaft to the next. These hydraulic pumps are available either with spur gears or even helical gears. The casing of a standard gear pump comprises two input shafts, a single output shaft, and dual gear trains.

Internal and external gear pumps are the two distinct types of gear pumps available in the market.

External Gear Pumps

External gear pumps move fluids with the help of interwoven external spur gears that turn in opposite directions. The teeth's meshing action reduces the volume required to release the oil on the output side. The oil that gets caught in the space between the gears that need to mesh again leaks out via the bearings and returns to the pump's suction side.

Internal Gear Pumps

The internal gear pump moves hydraulic fluid with the help of an internal gear that meshes with an external gear and a sector component. The axis of the external gear does not lie in the same place as the axis of the internal gear.

As the two gears turn, they come out of and back into the mesh. These actions create areas of discharge and suction. The sector separates the suction and the discharge areas.

Piston Pumps

As the name suggests, hydraulic piston pumps employ pistons to propel hydraulic fluid throughout the system. The pistons' exceptional sealing abilities enable for high-pressure operation with minimal fluid loss.

Axial and radial piston pumps, the two most common designs, use rotational motion to move the pistons.

Axial Piston Pumps

Axial piston hydraulic pumps feature internal cylinders arranged around a central axis to provide alternate suction and discharge flows. Each cylinder has pistons that connect to a wobble or swash plate. After that, these swash plates will link to the rotating shaft that will drive the pistons and draw them into & out of the cylinders.

Radial Piston Pumps

Radial piston pumps have a group of pistons arranged in a circle around the center of the rotor. As the rotor spins within the pump casing, it moves the pistons into and out of the cylinders, which draws hydraulic fluid into the cylinder chamber and then ejects it again.

The eccentric mounting of the rotor inside the pump casing causes this action. The valve in the pump's hub controls the flow into and out of the pump.

5 Safety Aspects to Consider With a Hydraulic System

Fri, 18 Nov 2022 20:46:01 GMT

Hydraulic systems are convenient frameworks that can help in heavy-load work environments. However, they also present risks and hazards to workers using them. Every hydraulic system owner should understand the risks of careless use, ways to avoid injuries, and safety mechanisms and features. Consequently, consider these five aspects of hydraulic systems that will increase safety in the workplace.

1. Improper Couplings

Every hydraulic system has a specific operating environment that determines the components it will use. You cannot use low-pressure parts in a high-pressure system and vice-versa. For example, you should not install a high-pressure pump in a low-pressure system. You might risk a rupture if you interchange these parts, which will damage the system and cost you some time from work and money to fix.

2. Pinhole Leaks

Pinhole leaks are common damages that occur on hydraulic pump hoses. The pinhole leaks are usually difficult to spot and might require some ingenuity. If you are fortunate enough, you might spot oil or fluid pools near the leak section, which can help narrow down the affected area.

If you cannot find the leak, do not run your finger along the hose line without proper protection. You might risk exposing yourself to the hydraulic fluid. Since the liquid in the system is pressurized, the pinhole leak might inject some fluid under your skin and cause gangrene, which results in severe pain.

Instead, use an object like a piece of plastic or wood to discover the affected area. However, you can also call a professional technician who understands the risks and will use the right tools to find and fix the leak.

3. Manufacturer's Safety Standards

Before you can operate the hydraulic system, read the instructions and guidelines carefully. You should understand all the hazards and risks involved with the system, the recommended operation parameters, and how to activate and deactivate the system after regular use or during an emergency.

For example, a manufacturer can include the maximum load that the system can bear within normal use. To avoid wear and tear, don’t put the system under the maximum load. Also, do not override any default settings set by the manufacturer. Settings like the relief valve can help keep you safe from excess pressure within the system.

4. Placement

The position and areas you place your hydraulic system in will determine if they will create a hazard for you or other workers within your facility. You should carefully consider where you will install your hydraulic system and train employees on how they can enhance safety while operating the appliance.

For example, you should always set up your hydraulic pump system like a jack on level ground. Do not prop up the hydraulic tool with any wedged item. Instead, use a solid and flat base. Additionally, you should not place your body under any load while you propped up the object with a hydraulic or jack. You might risk injury if the jack fails.

Avoid any open fires that might compromise the hydraulic system. Instead, cover it with a fire-proof material to prevent direct contact with the flame. Place any detachable components like the hose away from dirt and debris, which can contaminate the system.

5. Maintenance

Your hydraulic system features mechanical parts that will require regular maintenance and repair. This maintenance can identify issues, such as oil leaks and degraded hoses, that might affect the operation of your hydraulic components. Maintenance will also ensure you can resolve any issues that might create a workplace hazard.

7 Types of Hydraulic Cylinders and Their Uses

Wed, 26 Oct 2022 05:47:00 GMT

Hydraulic cylinders have many applications in the hydraulic industry. Most of the time, the cylinder performs work by converting the energy into fluids. The mode of conversion leads to many types of hydraulic cylinders. Find below the most common types of hydraulic cylinders you can buy.

1. Single Acting Cylinders

A single-acting cylinder has a port that works in one direction only. When a liquid or a gas enters the cylinder barrel, the rod will increase in size. For the rod to return to its initial state, the cylinder may use an external force or a load string. An example of single-acting hydraulic cylinders is the hydraulic jack used in the auto industry.

2. Double Acting Cylinders

A double-acting cylinder's ports are on both the rod and head parts. This design enables the hydraulic cylinder to move fluids more efficiently. The ports at both ends will control the movement of fluids within the cylinder. Hence, liquids and gases in double-acting cylinders can flow in two directions.

For example, if a liquid in the cylinder moves towards the rod section, the piston rod will shrink. In contrast, the piston rod will increase in size when the fluid flows toward the head section. The ability of the liquid to move in two directions means that a double-acting hydraulic cylinder can help to raise and lower equipment.

3. Nested Cylinders

The possible applications of hydraulic systems have significantly increased, and manufacturers are trying to develop more special designs. One of the latest designs involves putting together at least three cylinders. The combination of many cylinders creates a system with varying forces and speeds. Hence, hydraulic cylinders can do many things during a single stroke.

4. Rotating Cylinder

All the cylinders above don't rotate, which may limit their applications in many industries. That is why some manufacturers produce the rotating cylinder type with linear motion. The rotating cylinder design resembles that of a non-rotating cylinder in most aspects. The main difference is that the rotating cylinder contains a distributor component that can provide fluids to the rod and head ends of the cylinder. In addition, the rotating cylinder includes passages to allow the inflow of oil on both sections of the cylinder.

5. Low Height Cylinders

Low-height hydraulic cylinders may be ideal if you have limited space or want to move the cylinder around. The low-height cylinders have the exact working mechanism as many of the cylinders listed above but are lighter and smaller. However, you are only likely to find this type of cylinder in the single-acting model. Also, you can't use the low-acting hydraulic cylinder to perform activities requiring tremendous force.

6. High Tonnage Cylinders

Get a high-tonnage cylinder if your projects require a heavy lifting force. These cylinders can lift very heavy items that weigh over 1,000 tonnes. You can also use the high-tonnage cylinders for stability and protection for your loads. Hydraulic cylinders may use double-acting or single-acting working mechanisms.

7. Tie-Rod Cylinders

The tie-rod cylinder has a threaded steel rod to stabilize the components of the hydraulic cylinder. These cylinders also come with end caps to block fluid leaks. Hence, these cylinders have many applications in the industrial and manufacturing sectors. Those who buy tie-rod cylinders can expect easy repair, assembly, and maintenance of the cylinders.

Using Cylinders

Hydraulic cylinders are available in multiple models and styles. Your choice of a hydraulic cylinder will depend on your needs and budget. For the best hydraulic cylinders, reach out to Quad Fluid Dynamics, Inc.

Hydraulic System Components: How They Work and Why They Are Important

Tue, 27 Sep 2022 13:39:36 GMT

Hydraulic systems are in almost every type of machine. Therefore, you should know precisely how these components work. This information will let you know how efficiently your system works. Read on to discover some of the essential parts that work together to operate a hydraulic system.

Accumulator

The accumulator stores energy in the form of fluid under pressure and releases it when required. It acts as a buffer between the pump and the actuator, absorbing shocks and peaks in demand. Also, accumulators can restore system pressure in case of leaks or other issues that might lower internal pressure.

Filter

The filter removes contaminants from the hydraulic fluid. It is usually located between the pump and the reservoir or between the reservoir and the actuator. Filters ensure that the hydraulic system does not malfunction due to clogging or internal wear.

Actuator

The hydraulic actuator converts hydraulic energy into mechanical energy. It consists of a cylinder and a piston, which connect via a rod. The piston activates due to the hydraulic pressure, which drives the rod to move back and forth. This motion can perform work, such as moving an object or operating a machine.

Motor

The motor is the component of the hydraulic system that converts fluid power into mechanical power. The motor consists of a pump, a control valve, and a cylinder.

Pump

The hydraulic pump moves hydraulic fluid from the reservoir to the actuator. The pump ensures the actuator receives constant fluid volume to maintain system pressure. It also circulates the hydraulic fluid throughout the system.

Valve

A valve controls the flow of fluid in a hydraulic system. The control valve regulates the flow of fluid to the cylinder. The cylinder contains a piston connected to a crankshaft. The crankshaft turns as the piston moves up and down in the cylinder. This motion drives the load attached to the crankshaft.

A hydraulic system contains two types of valves: a directional flow valve and a control flow valve. Directional flow valves direct the flow of fluid by allowing the fluid to flow in only one direction. Control flow valves regulate the flow of fluid in a system by controlling the speed or pressure of hydraulic cylinders. Control valves can also shut off the flow of fluid completely.

Valves are located at critical points in the system, such as where lines branch off or fluids enter or exit components. By opening or closing these valves, the system can control the flow direction and amount of fluid.

Pressure Regulator

The pressure regulator regulates the pressure of the fluid in the system. The pressure regulator sits between the pump and the reservoir in the system. It controls the fluid pressure by regulating the flow between the pump and the reservoir.

Hydraulic Reservoir

A hydraulic reservoir is a tank that stores hydraulic fluid for a hydraulic system. The reservoir allows the fluid to expand and contract as it flows in and out of the system. It also helps to keep the fluid cool and prevents it from contamination.

Seals

Hydraulic seals prevent leakage in a hydraulic system. They are located between moving parts such as piston rods and cylinders. Hydraulic seals allow the system to maintain pressure by sealing the gaps between these moving parts.

Pipe System

Pipes transport fluids within a hydraulic system. They connect the pump to the actuator or reservoir. Pipes come in different sizes and materials, depending on the system's operating conditions. For example, the hydraulic system can use hoses if the operator prefers flexibility.

The hydraulic system is a series of mechanical components that create movement. If you know how important the parts of a hydraulic system are, you can maintain and assess your machine better. For example, you can detect machine problems by investigating if every component works correctly.

You should only seek services for hydraulic system components from a reputable company. Consider Quad Fluid Dynamics Inc for hydraulic rebuilding, manufacturing, and service.

The Benefits of Hydraulic Systems

Mon, 22 Aug 2022 15:44:02 GMT

Hydraulic systems are a common choice for different engineering applications. The basic system uses hydrodynamic principles, which resonate with the ideas of typical applications. In addition, such a system is easy to upgrade, especially in the dawn of computers and similar systems. The principles in hydraulic systems also form the basis for numerous industrial upgrades in the modern age.

However, what makes hydraulic systems unique and favorable? Any system that serves the interests of a business is a favorite choice. Technological developments in a particular sector also prompt firms to base their machinery on a specific system. If you want to pick machinery and technology for your business, here are a few factors that can sway you towards hydraulic systems.

High Efficiency

Hydraulic systems are more efficient than both electrical and pneumatic systems. The pump is usually more efficient in a hydraulic system than a pneumatic system. This efficiency depends on the system's ability to maintain the same hydraulic fluid viscosity across various temperatures. This attribute determines the power consumed and the work output of your system.

Electrical systems based on motors and similar devices are less energy efficient than hydraulic systems. The efficiency of hydraulic systems means that your business does a lot of work with minimal energy. The hydraulic system helps you cut down on the business overheads because of how efficient they are. In some cases, the hydraulic system can also be the selling point for vital customers in a highly competitive market.

Easy Control

The hydraulic system has better control over the amount of energy transmitted than most systems. Hydraulic systems regulate the configuration of the fluid and convert it into energy, especially mechanical power, for different applications. This ease of control makes the hydraulic systems ideal for machine tools, construction equipment, aircraft, and ships.

Hydraulic systems also seamlessly fit in various computer-controlled environments. Computer-aided control helps achieve different levels of energy transfer in a hydraulic system which makes the system accurate and precise.

Safety

Safety is a significant consideration in any engineering application. The safest methods are favorable since they result in fewer compensation claims and downtime, and you can quickly recruit people for such roles. In addition, safety directly influences the reputation of your business. Damages caused by equipment failure affect the firm's reputation in the market and labor pool in your industry.

The designer makes hydraulic systems passively and actively safe. For example, hydraulic systems designed to prevent people's limbs from being close to moving parts result in fewer accidents than other designs. These preventative methods are effective when the hydraulic system is in operation. The hydraulic system also uses one-way valves that prevent retraction when the system fails.

Ease of Maintenance

Hydraulic systems are easy to maintain. Some symptoms of a broken system include leakage of the hydraulic fluid, broken hoses, and poor response. These issues do not require unique expertise to diagnose. Your workers can easily detect and report the problems before they become problematic to the entire system. Therefore, you won’t need to call in an expert just to diagnose the problem.

In addition, the repair process includes the replacement of single parts in the entire system. For example, you may replace a hose or control system and ensure the system is functional again. Some remedies, such as changing hydraulic filters, are easy to rectify for your workers. The complex tasks are quick to diagnose, and solutions are easy to implement with the right expertise.

Pressurized fluids are ideal for different applications in your business. If you want to pick a technological solution for your firm, consult Quad Fluid Dynamics, Inc. , for purchases, installation, and maintenance. Using a reputable hydraulic solutions provider ensures that you have minimal downtime and that your equipment is durable.

Things To Consider When Choosing a Hydraulics Expert

Thu, 07 Jul 2022 03:59:17 GMT

When looking for a hydraulics expert to hire, create a list of companies from which to choose. The best firm to hire should be credible and fit your needs and budget, along with other considerations.

Here are some specific considerations to make before you hire an ideal hydraulics company.

Your Needs

The first thing to guide you in picking a hydraulic expert to work with is your needs. What type of hydraulic pump, hose, cylinders, or pipes are you looking for? Do you need standard hydraulic products or custom-made ones?

Different hydraulic companies offer various services and products. You need to know what you want to pick the ideal hydraulics expert for your needs.

Training and Experience

Experience guarantees you quality work. A company that has been in the hydraulic business for years has most likely used different products and determined the most suitable for each specific project. The technicians in the company have also perfected their skills to offer quality services.

However, while the company might have been around long enough to acquire considerable levels of experience, the same company might have hired new technicians recently. Hiring a company with new employees means that you will be getting new and probably inexperienced technicians.

Therefore, ensure you hire a company whose technicians have proper training and considerable experience to handle your needs.

Licensing and Insurance

Hydraulic pumps are expensive pieces of machinery, and their performance often affects your bottom line. Acquiring any hydraulic product or service from an unlicensed or uninsured company is betting your hard-earned money.

Licenses prove that local authorities have allowed a company to conduct business and that the company's services are legitimate.

Insurance coverage proves the company has secured its products and services. If there end up being faults with the products or services the company offers, the company is liable. They can take responsibility and compensate you accordingly.

Ensure the hydraulic company you hire has the correct licensing and insurance coverage.

Reliability and Flexibility

The best company to work with is a company with a quick turnaround for all projects. The longer a company works on your hydraulic project, the more money you are likely to pay.

Take your time and discuss your expectations with whoever is in charge. A chat with the manager should give you insight into whether the company you intend to hire can complete your project within your desired timeframe.

Convenience

If possible, opt for a one-stop shop. A company that offers a variety of hydraulic products and services saves you the costs of having to look for other services or products elsewhere.

The company should be able to send technicians to you when you need hydraulic services. A company with emergency services is even better.

Cost

Some companies use low prices as a way to lure customers. In many cases, low prices get you low-quality products and services. Hiring cheap companies could cost you much more in the long run.

Consider price offers after using all other criteria to narrow your search. Once you have two to three companies from which to pick your ideal hydraulic expert, go ahead and compare the companies' price offers.

Go for companies that check out on all your other considerations and offer reasonable prices for the company's products and services.

Regular maintenance is necessary to keep your hydraulic pump or any other hydraulic machine you have up and running. With the factors this article has highlighted in mind, you should be able to find yourself a good company to work with. For any hydraulic services, you can contact us at Quad Fluid Dynamics, Inc .

Common Hydraulic Operation and Maintenance Mistakes to Avoid

Fri, 03 Jun 2022 12:04:31 GMT

Even the tiniest mistakes during hydraulic equipment operation and maintenance can cost you a lot. The errors may turn minor problems into significant issues that kill the efficiency of the equipment. You may also have to spend a fortune on hydraulics repairs or replacement. Read on to learn about common hydraulic equipment mistakes to avoid and save yourself from such troubles.

Oil Change Mistakes

Hydraulic oil is expensive. You cannot afford to change it before it degrades as that leads to money wastage and system downtime. Furthermore, if you change the hydraulic oil before its ideal time, you increase the risks of fluid contamination, which adversely affects the entire system and makes it hard for you to reach your bottom line.

Follow the manufacturer's guidelines on how often you should change the hydraulic oil. The frequency of oil changes depends on service hours, but you need to consider other variables, including:

The depletion of additives
Air and water contamination levels
The operation temperatures

Water, heat, and aid contaminations make hydraulic oil degrade faster. Therefore, invest in quality system maintenance and clean it regularly if you want the fluid to last long.

Use of Wrong Type of Hydraulic Fluid

Hydraulic fluid plays a range of roles to ensure the efficient operation of your system. First, it is responsible for power transmission through the equipment. It also lubricates components within the hydraulic and lowers the chances of oxidation.

You must be cautious with the type of oil you choose for your hydraulic; otherwise, the wrong fluid will lower the equipment's efficiency, performance, and lifespan of its components.

The oil viscosity shouldn’t be too high or too low. If the viscosity is low, the hydraulic oil cannot adequately protect the system's components. In return, premature wear and failure of the pumps and motors can occur. Moreover, lack of protection results in generated contamination that further compromises the system's efficiency and lifespan.

On the other hand, if the viscosity of the hydraulic oil is too high, it cannot lubricate the system parts efficiently. Consequently, the components will wear prematurely. In the same way, high viscosity causes high fluid friction that may cause system power losses, which increases downtime cases.

Seek help from a hydraulic expert to advise you on the best hydraulic oil to protect your system's functionality and longevity.

Improper Filters Installation

Don't assume that all filters are equal. The functionality of a hydraulic filter primarily depends on how and where you place it. You should avoid the pump inlet and the drain lines if you want to extend the longevity of your system.

For starters, filters in the pump inlet restrict intake. Consequently, it shortens the life of the motors, piston pumps, and gear pumps. In the same way, filters in the drain line reduce the service life of the pump and motors, which lowers your chances of meeting your bottom line.

You should also be keen with the time you choose to change hydraulic filters. Suppose you replace the filters before the recommended period. In that case, you waste money, cause downtime, and increase contamination risks — similarly, failure to change the filters after the advised period results in clogs that compromise hydraulic flow. Eventually, the blockage causes hydraulic fluid bypasses that destroy other hydraulic components.

It would help to monitor the filter's pressure drop to determine if you need to replace the filters. A high-pressure drop signifies that you need to change the filters, while a low-pressure drop may indicate that the filters are already clogged.

Now that you understand the common hydraulic mistakes to avoid, you are in a better position to prevent sudden breakdowns and maximize your company's profitability. Contact us at Quad Fluid Dynamics Inc. for further inquiries about hydraulic systems and how to maintain them efficiently.

3 Indications You Need Gearbox Repairs

Sat, 09 Apr 2022 01:27:01 GMT

A gearbox plays an essential role in almost every motor-operating device, especially as the heart of power transmission. The gearbox helps speed the conversion of power transmission by offering a source of rotational energy for any motor-operating device to move and function at its peak performance.

All the same, a properly working gearbox with enough transmission fluid increases the lifespan of your vehicle and other motor-operating devices by preventing the effects of friction. Whether a manual or an automatic car, your gearbox is almost always susceptible to malfunctions.

Before such issues worsen, keep reading for the common indications you need to repair or replace your gearbox.

1. Failure to Switch Gears

Regardless of your vehicle's type of transmission system, struggling or a complete failure to switch gears indicates a problem with the gearbox. Common reasons for refusal to change gears include degraded transmission fluid, malfunctioning clutch master cylinders, or faulty torque converters.

Because the transmission fluid plays a crucial role in the proper functioning of your vehicle and gearbox, your gearbox can suffer problems due to the lack of enough lubrication, especially with low transmission fluid levels.

Over time, the transmission fluid fails to offer the needed lubrication that prevents excessive friction between components, especially when it's not regularly changed, thereby becoming degraded. When this happens, the fluid is also contaminated, and if it stays in the transmission system for a long, it makes gears challenging to shift as expected.

Therefore, if you experience constant difficulties switching gears even when the vehicle is in excellent shape, the problem is likely coming from the gearbox due to contaminated and degraded transmission fluid.

2. Unusual Burning Smells

Burning smells indicate low levels and sometimes overheated transmission fluid. Some of the causes of overheated transmission fluid include low fluid levels, radiators, and cooling systems problems, solenoid problems, and hot weather.

When there is a low transmission fluid level, your gearbox suffers malfunction due to reduced lubrication. When this happens, the system overheats quickly due to increased friction.

Also, burning smells can stem from the cooling system or radiators when they fail to keep all the elements inside the transmission system at their peak performances. For example, radiator malfunction means the engine won't operate as expected, thus leading to problems in switching gears or starting the vehicle, which also limits the functionality of the transmission fluid, thereby causing overheating issues.

On the other hand, for your vehicle to operate correctly, especially in starting and switching gears, it needs a properly working solenoid valve. The solenoid valve is responsible for the flowing in and out of the transmission fluid in an automatic transmission system.

As a result, if the solenoid valve suffers malfunctions, the transmission fluid automatically suffers problems getting into and out of the transmission system. All the same, your gearbox also suffers issues due to overheating.

3. Signs of Transmission Fluid Leakage

Although transmission fluid leakages are uncommon, you might sometimes suffer from them, especially with a faulty gearbox. You'll identify transmission fluid leaks at your parking site, driveways, and sometimes along the road.

Some of the top reasons causing transmission fluid leaks include a misaligned transmission pan gasket, problems with the transmission lines, and faulty transmission valves or solenoids. For example, the pan gasket helps keep your vehicle in excellent condition, considering it seals the transmission system with the gearbox accessories such as bells and more.

Unfortunately, failure for the pan gasket to correctly seal these fixtures leads to gearbox tear and wear, resulting in fluid leakage.

websitebuilder@thryv.com — Sat, 26 Mar 2022 17:30:42 GMT

With a hydraulic system in play, a hydraulic hose failure could ultimately damage your system as well as endanger your employees. You have no designated time when you should replace your hydraulic hose since rubber wears out for different reasons and in different ways. The best way to ensure your hydraulic hose does not wholly fail is to frequently inspect and replace it as necessary.

Discover some signs that tell you to replace your hydraulic hose.

Crushed Hoses

Hydraulic hoses bend up to a certain angle for full service. When the rubber for the manufacture of the hose wears out or weakens, the hose may crash, leading to a buildup of pressure inside. Pressure buildup in a hydraulic hose is often dangerous, which means that when you notice it, you need to replace the hose.

Failing to take necessary action on a crushed hose could lead to a damaged hydraulic system or a negligence lawsuit if an employee receives an injury.

Exposed Wires

Part of ensuring that hydraulic hoses serve their purpose effectively and for a long time is reinforcing the rubber with wires. With time, either due to wearing out or other environmental factors such as temperature, the rubber might tear away, exposing the wires. Exposed wires on a hydraulic hose mean that the hose's integrity is usually compromised and needs replacement.

When you notice wires on the surface of the hydraulic hose on any of your inspections, arrange to replace it. Again, leaving such compromised hoses unattended could be disastrous.

Oil Leaks Around the Fitting of The Hose

Urgently attend to a hose leaking oil. Contact a professional to assess the condition of the hose assembly in case it needs complete replacement. A leaking hose is uneconomical as it leaks hydraulic fluids that would have otherwise served you for a while.

The consequences of operating a hydraulic system that has less or no hydraulic fluid at all can be bad. Therefore, get a professional to look at the leaking points and direct you on the best approach.

Abrasions or Cuts Along the Outer Hose Cover

A hydraulic hose should not have cuts and abrasions on its surface. If you notice that your hose has weird scratches on the outer cover, have a professional check and possibly replace it.

You often have some normal scratches, especially if your hydraulic system works in rough areas. Such minute scratches should not be a worry. However, deep cuts can lead to hose failure and other problems if you do not address the cuts in time.

Cracked Fittings

When you come across cracked fittings, replace the hydraulic hose assemblies, especially if red rust is present. While broken fittings might lead to expensive hydraulic fluid loss and potential damage to the hydraulic system, red rust shows that the fittings have corrosion.

Corroded metal is usually fragile and, if not replaced, could lead to further corrosion, damaging the hydraulic system and potentially endangering employees. When inspecting your hydraulic system, make sure to note where the red rust is present and address it as soon as possible.

Whether or not you use them, hydraulic hoses will eventually wear out. The good news is that a failing hose will usually have one or a few of the signs above before ultimately failing. Regular inspections ensure that you find the discussed signs on time and conduct preventive maintenance if necessary.

4 Types of CNC Machine Repairs to Improve Drilling Efficiency

Tue, 15 Mar 2022 21:32:29 GMT

CNC machines can create sophisticated drilling and milling patterns. Whether you are in the manufacturing, mining, or automotive space, having a functional CNC machine should be a top priority for your business.

Sometimes, all you need is a simple adjustment to get your machines running more smoothly and efficiently. Discover four types of repairs that will increase drilling and milling accuracy to produce high-quality products.

1. Replace Your Control Valves

The control valve on your CNC machine is useful for regulating air pressure. If your valves work correctly, you can create precise cavities on your material for downstream manufacturing processes. Valves are one of the most common CNC machine repairs, and they are necessary for many jobs that require drilling. Even a small issue with valve performance could affect the range of motion in your equipment.

You can tell if your drill needs a new control valve by checking for dirt and low fluid levels. Dirt in your drilling equipment will lead to subpar results when working with hard materials such as wood, metal, or concrete. If your valves do not create an airtight seal while drilling, consider replacing them.

2. Check Your Hydraulic Power Unit Assembly

The hydraulic unit supplies power to the drill head and feed system during drilling. If this component doesn’t function correctly, it can cause inaccurate hole placement and poor-quality products.

You can test if your hydraulic power unit works correctly by checking the oil levels. If you notice low oil or dirt in your machine's oil supply, consider repairing the hydraulic unit. A faulty hydraulic assembly in your CNC machine could also result in low drill speeds.

Furthermore, dirty oil may interfere with the movement of your drill heads and reduce drilling accuracy.

3. Replace Dull Drill bits

The drill bit is the cornerstone of your CNC machine. Drill bits cut through your raw material, creating precise patterns and designs. Therefore, keeping your drill bit in good condition should be a top priority.

If your drill bit is not sharp, it will take longer to make a hole and cause inaccurate placement. A dull drill bit may also cause excessive wear on your CNC machine. One way to test if your drill bit is sharp is by looking at the sparks it produces.

Dull bits will produce little to no sparks, while a sharp bit will create bright sparks when it comes into contact with the material you are drilling. If your drill bit is underperforming, consider sharpening or replacing it.

4. Check Your Spindle Rotation

The spindle holds and rotates your drill bit, resulting in accurate cuts across your target material. If the spindle does not rotate correctly, you may notice excessive vibrations that affect drilling accuracy.

You have an easy way to check if your spindle works. A healthy spindle should make a humming noise, while a faulty spindle will produce a grinding sound.

A humming sound indicates that your spindle is guiding the drill bit, creating proper friction on your target material. Grinding noises are a sign that the drill bit is not firmly in place. If you notice drilling issues in your spindle and drill bit assembly, consider inspecting these components for damages.

CNC machines are essential tools for drilling and milling raw materials. Therefore, keeping up with repairs will improve efficiency and reduce waste. Quad Fluid Dynamics, Inc., offers a wide range of CNC repairs, rebuilds, and component upgrades. In addition, we customize the repair process to suit your specific needs.

5 Signs Your Hydraulic Cylinder Has a Problem

Tue, 01 Mar 2022 14:39:04 GMT

A hydraulic cylinder plays a pivotal role in the smooth and effective running of the machine it supports. If a cylinder develops a problem, then its machine might not be able to work efficiently or at all.

While a full cylinder breakdown is easy to diagnose, you sometimes get early warning signs that a cylinder has a problem that needs attention. How can you tell if a cylinder has a potential fault? Read this blog to learn five early warning signs of hydraulic cylinder failure.

1. Your Cylinder Makes Banging or Knocking Sounds

Hydraulic cylinders make some noise — however, these sounds shouldn't be alarming. Sometimes, a fault in a cylinder causes loud banging or knocking sounds.

You often hear these noises when the cylinder has a cavitation problem. There might not be enough fluid in the cylinder to enable it to run smoothly. Alternatively, you might have an aeration problem, in which your fluid levels might be adequate, but you have too much air in your system.

Cavitation or aeration problems create unusual pressure differentials in your cylinder. Any air bubbles in the system will then react to these pressure fluctuations by imploding and exploding. When this happens, you hear loud banging or knocking sounds.

2. Your Cylinder Moves Differently

Hydraulic cylinders should work smoothly. However, sometimes a problem cylinder will start to make jerking or juddering movements. This is a sign that the cylinder's piston and rod can't move freely or smoothly.

These jerking movements often result from too much friction in the system. For example, you might have problems with worn or damaged seals or parts. Alternatively, you might not have enough lubrication running through the cylinder to keep it running smoothly.

3. Your Cylinder Is Too Hot

Hydraulic cylinders have set temperature ranges. They shouldn't heat up past a certain point. You know you have a problem if your cylinder feels hotter than it usually does.

Sometimes this temperature increase is part of a bigger problem. For example, if a cylinder has juddering movements, then it will also probably start to heat up more because of the underlying friction problem.

However, excess temperature can also be a stand-alone problem or early warning sign of a potential breakdown. They can come down to problems with your hydraulic fluid or its levels. On the other hand, you might have a faulty oil filter.

4. Your Cylinder Runs Slow

A faulty hydraulic cylinder sometimes loses some power. It might seem to work more slowly than it should. It then affects its machine's operating speed and power. You'll notice that the machine cycle takes longer than usual.

Sometimes a cylinder slows down because of internal friction. However, this problem is more often caused by flow glitches. If the cylinder's flow is too low, then the system's actuator can't work to optimum efficiency.

A slow cylinder might indicate that you have a leak that affects internal pressure. You might see signs of an external leak around the cylinder, say, if a hose breaks. However, internal leaks aren't visible. Either kind of leak will slow down the cylinder because it has to work harder to create the right pressure levels. This takes more time, so the cylinder works more slowly.

5. Your Cylinder Uses More Power

If you notice that your machine is using more power, then you could have a cylinder problem. If your cylinder has to work harder to do its job, then it needs more energy to work.

Too much friction or a leak in the cylinder can cause this problem. For example, if you have a leak, then the cylinder has to pump through more fluid to compensate. This makes the cylinder work harder and longer.

While you can repair some hydraulic cylinder problems, others might require a rebuild or even a full replacement. For a quick diagnosis and fix, contact the experts at Quad Fluid Dynamics, Inc.

Hydraulic System Leakage: What to Know

Tue, 01 Mar 2022 03:27:10 GMT

Unfortunately, your hydraulic systems are prone to break, which leads to leakage. As a result, you may suffer financial loss.

In addition to the cost of the hydraulic oil itself, you may suffer loss through unnecessary energy consumption, decreased reliability, reduced equipment performance, damage to your hydraulic system, and increased maintenance costs. Discover what you should know about hydraulic leaks.

Leakage Detection

You may not notice leaks at times because no visual indications alert you to the problem. However, you need to identify these leaks as early as possible for a fast response. Discover some ways you can detect leakage on your hydraulic system.

Use Camera Systems

You may opt to use camera systems to monitor your equipment easily. For example, today, you can use cameras to detect movement to identify the possible sources of leaks. In this case, any drips that form around a certain location will alert the sensor camera.

Use Colored Oils

Use hydraulic oil with distinctive and unmistakable colors. In this case, if your hydraulic system has other fluids present, the colored oils will make it easier to diagnose any leakage.

However, if you don't want to change your oil types, you can use dyes that will change the colors of your hydraulic oil. Also, you can use dyes that are visible under ultraviolet light. Don’t be afraid to use these dyes because they won't affect your oil's performance.

Use Staff Education

Your staff members are some of the frequent users of your hydraulic systems. For this reason, educate your staff to look out for any colored stains or liquids on your machines.

Through education, your technicians, operators, and maintenance staff should be in a position to differentiate a hydraulic leak from other fluid leaks in your machine. For example, suppose you use a blue hydraulic oil. In that case, your staff should immediately report blue fluid leaks for faster response.

Leakage Sources

What are some possible sources of hydraulic leaks? Below are just a few.

Broken Pumps

Friction from parts that move increases the chances of possible leakage. In this case, the moving parts of a pump can loosen over time, which can cause the hydraulic fluid to leak through these parts.

Cracked Reservoirs

Despite the high tolerance of your reservoirs, excessive pressure on them can cause a crack and a possible leak.

Leaked Valves and Pipe Fittings

The joint where the hoses and pipes interconnect are weak spots. Valves can also get worn out over time, especially if your hydraulic fluid gets contaminated with dirt. As a result, the hydraulic fluid may leak out, which can cause damage to your system's performance.

Leakage Maintenance

Carry out regular maintenance on your hydraulic systems to prevent further damage to your equipment. Discover some of the maintenance procedures to consider for your hydraulic systems.

Purchase Quality Parts

Your hydraulic system depends on a lot of pressure to operate. Additionally, it needs to operate for a long time with minimal maintenance. For this reason, ensure you get quality parts to increase performance and reduce maintenance costs.

Replace Filters

Filters help to prevent contaminants from getting into your hydraulic systems. However, they can wear out quickly, so change them often to enhance their performance. Also, ensure you wear protective equipment to avoid injury.

Lubricate Regularly

Lubricate your hydraulic parts often during maintenance practices. These parts may include plastic, rubber, or metals that will age with time and crack. Therefore, lubricate these parts to reduce frictional wear and tear and extend lifespan.

Your hydraulic leak may cost you more in the long run, so get professional services to avoid further damage. Quad Fluid Dynamics, Inc. , provides you with high-quality professional hydraulic rebuilding, manufacturing, and services. Contact us today for your hydraulic maintenance needs.

6 Hydraulic Pump Maintenance Tips

Fri, 08 Oct 2021 20:19:05 GMT

Hydraulic systems are common in many manufacturing and industrial operations. The systems help lift heavy loads and press parts, which helps save time, promote safety, and complete tasks quickly and efficiently.

While everyone wants their equipment to last, machines eventually break down, start piling up repair costs, and ultimately call for a replacement. However, proper maintenance can keep your pump in top working condition so it can remain operational for a long time.

Discover a few tips to keep in mind.

1. Stick to the Maintenance Schedule

First and foremost, have in place an efficient maintenance schedule for your hydraulic pump. Regular maintenance allows you to identify any issues before they occur and take action. Do not wait until the pump fails for you to give it proper attention. Avoid costly repairs by routinely inspecting the machine and fixing any issue that you spot.

2. Change the Hydraulic Fluid Often

Keep tabs on the number of hours the pump has been operational to know when to check the fluid level in the reservoir. Without the proper fluid levels, the pump does not build enough pressure to get the job done. For example, with low oil levels, the system draws in air and causes pump cavitation and reduced system pressure. Ensure that you stick to the fluid change schedule that pump manufacturers provide.

Also, ensure that you use the correct type of hydraulic fluid for your pump. You want to use the type of oil that improves the pump's efficiency.

Also, consider the cleanliness of the oil, as it plays a pivotal role in extending the life of the pump and other vital components such as gaskets and seals.

3. Clean the Suction Strainer

A suction strainer sits in the hydraulic pump tank. The suction strainer is a crucial hydraulic pump component and keeps oil debris from the pump. Due to its important role, clean it regularly.

4. Change Filters Often

You may not identify pollutants by visually inspecting the hydraulic fluid. Filters effectively remove all particles in the oil, so replace them according to schedule. Clean the filter bowl, too, when necessary.

An oil filtration system ensures that only clean oil is available for your pump. Always check the oil filter blockage indicator to see if the filter is clogged up.

5. Check Pipe and Pipe Connections

Routinely inspect pipe and pipe connections and the hose systems. Damage to the hoses can impede fluid flow or cause the pressure to leak. Also, check for internal issues that can clog the hose. Do not forget to check the couplers, fittings, and pipes.

The couplers should always be clean to avoid contamination. The fittings should be a little loose, and the pipes must not have any rust. Leaks can cause the system to overheat or consume excess oil, so do everything possible to prevent leaks in your hydraulic system.

6. Scan the Electronic Drive Motor

A handheld infrared thermometer will help you check for any overheating issues on the electric drive motor. Check for hot spots on the rotor bearings or the pump's housing. You must regularly service these areas to prevent extended equipment damage.

Also, use the infrared thermometer to check the temperature of the hydraulic valves. If the temperature exceeds 150 degrees, this is a sign the valve is sticking. Closely monitor the oil cooler and the oil tank for any signs of overheating.

How well you maintain the hydraulic pump determines its shelf life. If you notice any issues with your hydraulic pump or want to carry out scheduled maintenance, contact Quad Fluid Dynamics, Inc. , for all your hydraulic maintenance needs.

Your Choice of Hydraulic Fluid: 3 Things to Consider

Thu, 09 Sep 2021 17:06:07 GMT

Hydraulic fluid should protect your hydraulic equipment against rust, friction, and oxidation effects. Different types of fluid have different properties. The differences make each type of hydraulic oil suitable for a specific application.

Characteristics such as water resistance, viscosity, and heat dissipation are critical aspects that determine the hydraulic fluid performance. Therefore, your choice of fluid needs to meet certain performance requirements of a specific application. You should also keep the operating conditions in mind to help you make the right decision.

But what major factors should influence your choice of hydraulic fluid?

1. Hydraulic Pump Design

The design of your hydraulic equipment could influence your decision when selecting a suitable fluid. The most common types of hydraulic pump designs include:

Vane pumps . These pumps use rotary motion to ensure a constant fluid flow even with changing pressures. They can also operate with very little noise.
Gear pumps . They use a system of interconnected gears to pump hydraulic fluid. Gear pumps work best for high-pressure operations.
Piston pumps . They use mechanical distribution to create high amounts of pressure in the hydraulic fluid with minimal effort. Piston pumps are best suited for applications where high flow rates are a priority.

Generally, each type of pump has different performance requirements. More specifically, viscosity and lubrication needs may differ from one pump to another.

For instance, vane pumps would require you to use a hydraulic fluid with a viscosity of between 14 to 160 centistokes. While these pumps have superior fluid flow volumes, maintenance can be quite costly because they wear out much quicker.

Piston pumps, on the other hand, require fluid with a viscosity of about 10 to 160 centistokes. Your choice of hydraulic fluid should meet this requirement for the best performance and protection.

Keep in mind that gear pumps are more flexible and can work with a wide fluid viscosity range.

2. Type of Application

The system application is critical in your choice of hydraulic fluid. Not only does the right fluid increase the system's efficiency, but it also extends the life of your equipment.

You may need to first identify what stands out about a specific application before you settle on a fluid type. For instance, a garbage truck is likely to be out in the open for long periods. Rain, debris, and other contaminants are likely to affect the reliability of the fluid in its hydraulic system. Additionally, hydraulic fluid may leak out from the truck's hydraulic system over time.

In such a case, you may do well with a less expensive hydraulic fluid instead of going for the most expensive choice in the market. The cost of refilling the fluid every now and then can quickly add up. Therefore, you may want to invest in a more affordable fluid to spread out your maintenance costs.

Similarly, if the hydraulic pump system runs in a clean and heavy-duty environment (where maintenance is critical), a more premium choice of fluid would be ideal. Still, the viscosity may be an additional requirement to keep in mind.

Most times, a high-grade fully synthetic fluid should suffice. Such fluids may have superior thermal properties, critical to your application.

3. OEM Recommendations

Sometimes, your Original Equipment Manufacturer (OEM) may suggest a specific type of hydraulic fluid for your hydraulic equipment. Oftentimes, the recommended fluid is a proven choice that guarantees the best performance.

Additionally, the warranty agreement may limit your options to only the OEM's choice of fluid. If so, you may want to go by the specifications to protect yourself from any losses in the future.

If you're still unsure of the right type of hydraulic pump fluid to use for your equipment, reach out to Quad Fluid Dynamics, Inc. , today.

Hydraulic Operation: What Function Does Hydraulic Fluid Serve?

Wed, 04 Aug 2021 20:27:55 GMT

Your hydraulic pump - or any other hydraulic-based system - can't function properly without hydraulic fluid. The fluid is incompressible, an ideal property for energy transfer by hydraulic systems.

When a hydraulic system is in operation, hydraulic fluid is pumped from the system reservoir to the other hydraulic components. The fluid needs to meet certain requirements for your system to enjoy better efficiency. Learn more about hydraulic fluid and its most important operational characteristics.

Why is Hydraulic Fluid Important?

For modern hydraulic systems, pressure and temperature are among the most important operational elements. Thus, your choice of hydraulic fluid should meet these requirements.

Hydraulic fluid is mainly a medium for energy transfer. However, the fluid has other equally important functions. These other functions rely on your hydraulic fluid's characteristics, some of which are realized by adding additives. With additives, fluids can be designed to perform the following functions better.

Heat Transfer

A hydraulic pump generates large amounts of pressure to help move hydraulic fluid through the various machine components. Pressure is critical in the regular operation of a hydraulic pump system, but it can create a lot of heat. This heat comes from the friction generated as fluid molecules brush against machine components.

Unfortunately, too much heat can damage your hydraulic pump. The hydraulic fluid distributes the generated heat across the system to help reduce the heat intensity. The hydraulic fluid then enters a cooling mechanism that takes away the excess heat. But if your system generates less heat, the reservoir can double as a dissipation mechanism that releases the pent-up heat.

On the other hand, hydraulic fluid can become too cold when you operate your pump in cold temperatures. You can combine your pump with an external heater, which in turn warms up your hydraulic fluid. In doing so, the fluid keeps your system within the rated temperature limits and prevents damage.

Lubrication

Hydraulic components work under intense pressure. Therefore, these elements are susceptible to frictional wear and tear.

Hydraulic liquid lubricates the moving internal parts of a hydraulic system, such as the valve plate and piston slippers. Without sufficient lubrication, your hydraulic pump can only serve you for a short while before malfunctioning.

To effectively lubricate your pump's internal components, the hydraulic oil needs to meet certain industry standards. Manufacturers perform various tests to determine critical operational properties such as pour point, viscosity, and viscosity index.

Hydraulic fluid should have good operational properties for sufficient lubrication. For instance, for lower ambient machine temperature, the ideal hydraulic fluid should have a low pour point and viscosity. Pour point describes the low temperature limit at which the liquid can still pour out without congealing.

For all-weather hydraulic machines, the hydraulic oil should generally have a higher viscosity index to ensure proper machine lubrication.

Contaminant Removal

Although the ideal hydraulic system should be fully sealed, water might still enter your system and mix with your hydraulic fluid. Solid contaminants, including dirt particles, can also contaminate your hydraulic fluid and accelerate deterioration.

Contaminants in your system significantly reduce efficiency and eventually damage your system. Fortunately, a hydraulic system has filters to trap contaminants and prevent them from causing more damage.

The hydraulic fluid transports the contaminants to the pump filter, where you can quickly get rid of the impurities. Without the filter, the impurities can make your hydraulic fluid compressible and lower the overall system performance.

Making the Right Choice

Operating your system successfully requires you to choose the right hydraulic fluid for your equipment. You have to ensure that your choice of fluid can handle the rated operating limits of your system. At Quad Fluid Dynamics , we can help you decide on the proper fluid for your needs without sacrificing performance.

4 Signs of Hydraulic Pump Failure

websitebuilder@thryv.com — Mon, 05 Jul 2021 14:29:09 GMT

Hydraulic pumps support a magnitude of production systems, and no matter how much preventative maintenance you do, the pump may still wear out and age. In addition, after withstanding the intense internal pressure within the hydraulic system, the pump will show signs of failure.

Learn about four characteristics of hydraulic pump failure.

1. Slow Operations

When the performance of your pump degrades, that is often a telltale sign of failure. To check for slow operations, confirm the speed or flow of the pump. If the cycle lengths of the hydraulic pump are slower than usual, then an issue within the pump needs repair; otherwise, your system may soon fail.

Your hydraulic pump can be slow because of multiple reasons, including internal or external leaks, low pressure, or high temperatures, which are also signs of pump failure.

2. Unusual Sounds

Hydraulic pumps are often silent unless their components are subject to wear and tear. These unusual sounds can result from hydraulic aeration or cavitation.

With aeration, air contaminates the hydraulic fluid, and as the fluid circulates within the hydraulic system, the constant compression and decompression cause knocking and banging sounds from within the system. In addition, because of aeration, the hydraulic fluid can begin to foam and cause erratic actuator movements, which degrade the fluid and cause components damage from overheating and loss of lubrication.

As for cavitation, the fluid volume demand within the hydraulic circuit exceeds fluid supply, causing a pressure drop past the liquid's vapor pressure. In turn, the fluid forms vapor cavities that implode during compression, causing a knocking sound. Cavitation results in metal erosion that damages components of the hydraulic pump, leading to mechanical failure.

3. Interior and Exterior Leaks

Oil can leak inside the pump, either through the valves or actuators or outside the pump from a burst hose. When oil leaks, it affects the overall flow of liquid within the pump, which results in a pressure drop in the system. Eventually, the pump will perform much slower, leading to complete failure.

Still, in line with leaks, you may also notice failed seals. The seals keep liquids within the pump to ensure proper flow within the system, but if the seal breaks or you see a misaligned or bent rod, fix these issues before the pump can no longer function effectively.

4. High Fluid Temperature

With preventative maintenance, check for fluid contaminants such as a buildup of dirt and debris in the reservoir. If the buildup of dirt in the reservoir is too much, the waste will disrupt proper airflow, causing the reservoir to be unable to dissipate heat. In turn, the fluid becomes hot, and its viscosity falls below the optimum value for the system's components.

Without heat dissipation, fluid temperatures can easily reach and surpass 180°F (82°C), which is detrimental to the hydraulic pump as the hot fluid will damage the seals and cause fluid degradation.

What is worse, the above signs like aeration, cavitation, and internal leaks can significantly increase the heat load within the system, reducing the practical life of the hydraulic fluid. Additionally, as the liquid continues to heat up, the oil film thins, meaning it has a low viscosity. This is detrimental to the pump because it will damage from inadequate lubrication.

Hydraulic pumps can withstand intense working pressure using their sturdy components. However, with time, its components degrade, performance turns sluggish, efficiency decreases, and flow cycle lengthens.

If you notice any of these signs in your hydraulic pump, repair or replace your pump. Contact Quad Fluid Dynamics, Inc. , today for hydraulic repair services. We look forward to helping you.

3 Common Hydraulic Press Problems, Causes, and Prevention Options

websitebuilder@thryv.com — Fri, 04 Jun 2021 20:00:20 GMT

If you rely on a hydraulic press to shape metal components or perform other tasks at your facility, then you can experience productivity loss when your press malfunctions. For this reason, you should be aware of the most common hydraulic press problems and how to prevent them to help keep your business running smoothly at all times.

Read on to learn about three common hydraulic press problems, their causes, and steps you can take to help prevent these problems before they develop.

1. Oil Leaks

One of the most common hydraulic press problems is an oil leak. These oil leaks cannot only create a mess and potentially cause your hydraulic presses to begin malfunctioning, but they can also pose a great fire hazard. When oil leaks from a hydraulic press, it is often released in mist form because this oil is so highly pressurized and hot. This mist often goes unnoticed until it ignites when it hits an open flame and quickly starts a fire.

Oil in a hydraulic press can leak from the system's piston oil seal, pump plunger, or release valve rod.

An overfilled oil reservoir, a contaminated check ball, or damaged piston packing is often what causes leaks from the piston oil seal. To prevent these problems, never overfill your oil reservoir, clean or replace check balls regularly, and replace piston packing before it begins to show signs of wear and tear.

When oil begins to leak from a pump plunger or release valve rod, the cause is often loose packing nuts or worn packing. Prevent this problem by inspecting the machine and tightening packing nuts when needed and by replacing packing on a regular basis.

2. Press Not Building Pressure

Another common hydraulic press problem is a press that will not build pressure. Unlike oil leaks, the cause of a hydraulic press system that stops producing pressure can vary greatly.

Before you begin examining your machine for other problems, first check the system directional control setting to ensure it is not reversed. If the setting is optimal, then next, determine if there is a blockage in the system that is preventing fluid from reaching the hydraulic pump. A pump that is not receiving enough fluid can stop building pressure.

If your pump is receiving fluid, then the cause of the lack of pressure may be a problem with the machine drive motor. Damaged or misaligned drive motors can often create pump pressure problems.

While pump pressure problems can occur unexpectedly, you can help prevent them by properly maintaining your equipment and taking steps to avoid hydraulic fluid contamination that can lead to pump clogs.

3. Hydraulic Drift

Another common hydraulic press problem is hydraulic drift. While hydraulic drift can lead to many hydraulic press problems, the telltale sign that your press is suffering from this problem is a press that stops operating smoothly and instead makes jerky movements during operation.

While the main cause of hydraulic cylinder drift is unequal pressure in the cylinder across the piston, the cause of this pressure imbalance can stem from multiple hydraulic press problems.

Sometimes, contaminated hydraulic fluid causes hydraulic drift. Hydraulic drift can also occur when a hydraulic press system overheats. When a system runs too hot, the excess heat can damage system seals by causing them to become too hard and brittle to function properly. Another possible cause of hydraulic drift is a piston rod seal leak. If this leak becomes severe, the piston rod will often stop working completely.

To help prevent hydraulic drift, inspect your system's hydraulic cylinder on a regular basis. During this inspection, check the cylinder piston for corrosion that signals it needs replacement before cylinder drift begins. Also, examine system seals and connection devices for wear and tear regularly and replace these components when needed.

If your business is equipped with one or more hydraulic presses, then you should understand the most common hydraulic press problems, their causes, and how to prevent them. Contact the hydraulic press experts at Quad Fluid Dynamics, Inc. for all of your hydraulic press needs today.

Hydraulic Pump Performance: 5 Causes of Operational Inefficiencies

websitebuilder@thryv.com — Fri, 28 May 2021 14:17:31 GMT

If hydraulic pumps underperform, this can cause significant losses due to decreased productivity. Therefore, if your commercial or industrial machinery show signs of pump decline, plan for immediate troubleshooting and repair. Moreover, consider the below-outlined causes of operational inefficiencies in hydraulic pumps to prevent a recurrence.

1. Fluid Incompatibility

The flow of incompatible fluid in a hydraulic pump can compromise equipment function and performance. When purchasing a pump for your machinery, consider the process fluid you use in your operations before selection. The critical liquid properties for identifying the right pump include specific gravity, operating temperature, vapor pressure, and particulates or abrasives.

If you have the wrong pump for your hydraulic fluids, replace the old component with a compatible one to prevent long-term inefficiencies.

2. Improper Sizing

An undersized hydraulic pump is prone to inefficiencies and malfunctions. The component will often experience strain after installation, and the performance can decline over time before complete failure. Therefore, consider the suitability of your hydraulic pump size for your machinery. Check on critical aspects like flow rate, total volume, discharge pressure, and power rating.

Oversized pumps are also unsuitable for efficient equipment function. The extra horsepower available in a large hydraulic pump will often increase energy wastage. Moreover, the unit could cause strain to other connected components.

3. Poor Piping Design

The inefficiencies in your hydraulic pump could be linked to the connected piping. A poor design can increase the strain on pumping components and cause a decline in performance. Check these elements and ensure the size is appropriate for the pump flow rate and pressure. The right diameter will often promote consistent fluid flow and reduced pump stress.

The weight of connected pipes can damage the pump by pulling at connection points. Therefore, when dealing with heavy hosing, use hangers or other supports to support the mass. The connection points are vulnerable areas for leakage when the fluid flows into and out of the pump. Use compatible fittings capable of withstanding the pressure and temperature of the fluid.

4. Incorrect Operation

If the pump operates contrary to the manufacturer's instructions, operational inefficiencies can arise. For instance, the wrong controller settings can cause an irregular flow of hydraulic fluid during operation. Consequently, the equipment might not function at the optimal capacity. Other critical settings include system relief, pressure compensator, and drive motor speed.

The operator must monitor these aspects to prevent inefficiencies related to human errors. Keep in mind that excess adjustment or constant knob-turning can also compromise pump function. Therefore, choose a well-trained specialist for hydraulic equipment management. Additionally, restrict the change of equipment settings by other workers without approval.

5. Irregular Upkeep

The core of consistent and efficient hydraulic pump function is proper maintenance. Therefore, follow the manufacturer's guidelines for regular system upkeep. The most critical task is housekeeping. Clean the pumps to prevent accumulated harmful grime and particles. Clean pumps are also easier to troubleshoot in case of a breakdown.

The quality of hydraulic fluid affects the operational efficiency of pumps. If old and degraded fluids remain in the equipment, the equipment performance can decline. Avoid this problem by changing the fluid as recommended. Choose high-grade fluid to improve pump performance and prevent component damage.

Also, monitor the function of hydraulic pumps in your equipment. Failure often occurs in machines due to late detection. If you identify a decline in the early stages, a complete breakdown will often not occur. The best approach to monitoring is gauge installation in the discharge and suction elements. Additionally, plan to regularly inspect the hydraulic pump assembly.

If you have noticed a decline in hydraulic pump function in your commercial or industrial machinery, do not ignore the warning signs. Contact us at Quad Fluid Dynamics, Inc., to comprehensively assess this component and subsequently repair and restore it if necessary.

4 Signs Your Hydraulic Pump Pilot Device Needs Repair

Tue, 13 Apr 2021 19:24:08 GMT

Hydraulic pumps offer multiple options for control. While many pumps include computer kits and automated options, a pilot device creates more precise and manual control of your hydraulic pump. While human error can often result in problems, several signs may indicate malfunctions in pilot devices.

Check out four signs of hydraulic pump pilot device problems found in equipment. Some of the signs may appear more subtle at first, but early detection can ensure you get the proper repairs done quickly and have your equipment operate the way it should.

1. Stuck Buttons

Some of the more advanced hydraulic pump equipment uses advanced push buttons for controls. The push buttons could have color codes for different processes and are often spring-loaded to easily pop up and down when in use. The wear and tear on the pump use may result in push buttons getting stuck.

If a button goes down and doesn't come up, you could deal with a major jam and not have proper access to the pump. A repair technician can replace the button or repair the spring function to help prevent problems. If one button is stuck, all of the push buttons will still go through the inspection process to ensure the problem doesn't happen again with a new button.

In some cases, a repair technician may notice debris build-up or grease as the main cause of the issue. If you find out the main cause, then you can take preventative measures to ensure the problem doesn't occur again.

2. Loose Levers

The levers and joysticks installed on pilot devices are supposed to give you precise control. Over time, the levers could loosen up and not offer the same precise movements. Gears may break down and internal parts could have cracked or completely snapped. Without the precise lever movements, the pump controls could become challenging to maneuver.

A loose lever may also go past a stopping point. Levers can typically only move or rotate so far. If a lever expands beyond its reach, the pump may lose control and result in some major errors.

3. Stiff Pedals

While any loose part is a problem, additional problems could occur with stiff pedals. Some pilot controls include foot controls for easy start and stop functions. If a pedal is too stiff or completely jammed, the pedals may prohibit regular movements like forward motion, reverse motion, and braking.

The pedals may have jammed parts or need extra lube to work properly. A repair shop can inspect the pedals and the connected pieces to restore the proper movements. In some situations, a fluid leak could have cause rust to form and jam the pedals. A complete inspection will cover all the areas so the same problem does not occur again with new brakes.

4. Slow Response Time

When you use pilot devices on your pumps, you should have real-time results. If you press a button and experience a two-second delay, then you could run into major problems or have trouble fully operating the pump. A slow response time may have to do more with internal computer controls rather than the physical components.

Full pump troubleshooting will help determine the source of the issue and ensure that actions take place at the same time you press input buttons or use a joystick control. Digital computer scans will give detailed information including hardware functions. A part may overheat and decrease the response time, much like how you would click a mouse on a slow computer.

For software issues, repair services may issue firmware updates that improve the performance of the pilot devices.

A Quick Guide to Hydraulic Cylinder Pitting and Repair Options

Wed, 17 Mar 2021 21:13:17 GMT

The daily operations of a hydraulic cylinder require smooth operations from the piston rod as it extends outward and back again over and over. One of the minor problems that can turn into a big issue is rusting. Rust formation can lead to pitting and major operation problems.

Follow this guide to learn about hydraulic cylinder pitting and the repairs necessary to make your hydraulic cylinder fully functional again.

What Is Hydraulic Cylinder Pitting?

Pitting occurs when rust forms on piston rods. As the rust eats away at the rods, small grooved edges appear in the rods, commonly referred to as pits. The pits can form around the whole rod and may include small sections at first and expand more as the rust forms.

If you purchase used hydraulic cylinders, pitting is one of the major problems you should look for in the product. Pitting can dramatically change the performance and operations of a hydraulic cylinder.

How Does Rust Form and How Can You Prevent It?

The main way to prevent pitting is to prevent rust formation. Typically, rust will form when multiple conditions meet together. The first occurs when you have a hydraulic cylinder that is only used seasonally. When the piston rods don't actively move, moisture buildup may occur and cause rust to form.

Rust forms at a much faster pace when the equipment is outside. Daily weather or morning moisture can cause rust to form on the pistons. If you leave the pistons extended out from the housing, then the rod has exposure to the air and is more vulnerable to rusting.

Not only will the piston rods rust, but the open chamber of the cylinder may become vulnerable to rust. When the piston rods extend outward, air and moisture can leak inside the cylinder, creating issues. Rust buildup can result in jams or cylinders that do not operate smoothly.

When storing equipment with a hydraulic cylinder, try to keep the equipment indoors as much as possible. Position the equipment so the piston rods are inside the shaft and protected from excess moisture. If you must keep the equipment outdoors, then consider a protective cover like a tarp for when the equipment is not in use.

Should I Operate the Hydraulic Cylinder After Pitting Has Occurred?

If you notice your hydraulic cylinder has pitting, seek out repair services and avoid any equipment use. If you choose to operate the equipment, the piston rod pitting may damage the seals on the cylinder. Essentially, you could cause more damage and cause other fluids to leak outside of the equipment.

Not only should you leave the equipment as it, but avoid any rust removal from the cylinders. If you scrape or scrub the rust, more unintended pits may appear. A full inspection by a repair company can detect all of the rust and built-up pitting.

What Are Pitting Repair Options?

Minor pits in hydraulic cylinders can go through a repair and restoration process. Professional repair specialists can help fill in the pits and restore the piston rods. Once repairs are complete, the repair professionals can run full tests on the hydraulic cylinders.

If pitting has become extreme, then a repair company can replace the piston rods all together. Starting fresh with new piston rods will help improve the operation of the equipment and prevent further pitting or problems in the future.

Something Wrong With Your Hydraulic Pump System? A Troubleshooting Guide

Tue, 23 Feb 2021 20:41:23 GMT

The pump is a crucial component in a hydraulic system but also the most vulnerable to wear. When the pump fails, your hydraulic system usually suffers a loss of power and speed, unusual noises, elevated temperatures, and erratic performance. When a pump wears, you have a great risk of contamination of the system through debris.

Pump replacement is expensive, so for this reason, you should maintain it to keep it in optimal shape. Discover some common pump problems and the techniques pump professionals use to troubleshoot them.

1. Air Leaks

Air leaks cause multiple problems such as slow hydraulic response and loss of control for the system. A professional pump contractor first checks the suction side of the system for any leaks. Other areas where an air leak can occur include the pipe fittings, joints in the pump inlet line, rod seal, unions, and pump seals.

The pump expert uses an ultrasonic gun and other sophisticated equipment for the inspection. The professional will also check the oil reserve levels and any problems with the design of the return line. If they identify a problem, the technician takes corrective measures to eliminate air leaks and ensure your hydraulic system works optimally.

2. Cavitation

Cavitation is the rapid creation and collapse of air bubbles in a fluid, which affects the performance of your hydraulic pump and its lifespan. The problem occurs when liquid in your hydraulic pump turns to a vapor at low pressure.

As the pump liquid continues to flow, the bubbles implode and cause a shock wave. The force hits the impeller and causes vibration in the pump. Such vibrations can cause mechanical damage and make the pump be at risk of failure.

Some problem areas the pump professional inspects during cavitation troubleshooting include:

Overall condition of the pump suction strainer
Clogged pump inlet system
Blocked air breather
High oil viscosity
Wrongly sized suction strainer
Poor quality oil
Pump speed

The pump technician checks each of these items and recommends the best solution. An oil change to a higher quality product can reduce sludge and varnish formation. To tackle pump cavitation, the technician can increase the size of the strainer, clean any clogged plumbing, or replace worn-out parts.

3. Pump Contamination

Pump contamination can originate from different sources. Some debris and chips left behind in the pump's production can contaminate the system but with no internal damage. New oil can also introduce contaminants into the system and can score internal components and damage the system.

A poor quality breather is another source of pump contamination. The breather lets in contaminants such as dirt, soot. and ash into the system. Water or moisture is another cause of contamination in the pump system, and it affects oil viscosity. Water contamination corrodes the pump body and other crucial components.

The pump technician checks the maintenance record of your pump system and drains the liquids after the inspection. The pump inspection also involves detecting possible water leaks and using sealants to eliminate the contamination.

4. Poor Delivery or Flow

If your pump suffers from low, slow, or no liquid flow, the symptoms affect the efficiency of the entire system. A pump contractor checks at multiple areas such as the level of oil in the reservoir, condition of the shaft and vanes, or oil viscosity.

Poor pump delivery can arise because of clogged intake, shaft direction problems, low oil level, broken couplings or shaft, and slow pump speed. Every hydraulic system is unique, and the pump professional recommends tailored corrective measures based on the assessment of the system.

The hydraulic pump is a versatile component and a reliable source of power for multiple applications. However, this hard-working part is also vulnerable to damage and can affect the performance of the hydraulic system. Professional maintenance helps prevents pump failure through early corrective measures.

Hydraulic Pump Overheating: Hazards, Causes, and Solutions for This Problem

Wed, 20 Jan 2021 15:18:36 GMT

Hydraulic pumps generate heat while they run. However, hydraulic fluid temperature should never exceed 180 degrees F (82 degrees C) under normal working conditions. If your hydraulic pump temperature rises above this, then that is a sign that your pump is likely overheating. One of the most common causes of hydraulic system failure is a hydraulic pump that runs too hot or overheats.

Learn about the hazards of a hydraulic pump that runs too hot, the most common causes of this problem, and the ways to remedy this common pump issue.

Overheating Hazards

When a hydraulic pump runs at a too-high temperature for too long, it can ultimately lead to pump failure. Once a hydraulic pump begins to fail, it can potentially damage the entire hydraulic system by sending contaminants and debris into the system that can damage its other components.

In addition, when some hydraulic fluids are subject to high temperatures, they can thin and lose their viscosity. When hydraulic fluid is too thin, it is much more likely to leak, and fluid that has lost its viscosity cannot lubricate your pump properly. Extremely hot fluid can also damage pump seals, further increasing the chance of a pump leak.

Some hydraulic fluids thicken and oxidize when exposed to high heat instead of thinning. When hydraulic fluids are too thick, they can restrict flow throughout the entire hydraulic system, which leads to your system heating up even further.

The sooner you determine why your hydraulic pump is running hot and repair the cause of the problem, the less likely your hydraulic system will develop irreversible damage or fail completely.

Overheating Causes

Hydraulic pumps overheat for many reasons. Just a few of the most common causes of hydraulic pump overheating include:

Contaminated hydraulic fluid . When fluid has debris and dirt, contaminant particles can quickly build up on hydraulic system filters, leading to filter clogs. Your pump has to work harder to pump fluid through clogged filters, which leads to overheating.
Aeration . Air leaks at seals and fittings on your hydraulic system components can lead to air entering your system and forming bubbles in your fluid. Air bubbles generate heat when your system compresses them and then pass this heat into the surrounding fluid, overheating it.
Low reservoir fluid . Since your hydraulic system releases some of the heat it creates into reservoir fluid, a low reservoir fluid level can contribute to overheating.
Blocked or damaged heat exchanger . This component is also an important part of your hydraulic pump's cooling system. If it is blocked or damaged, then it cannot help remove heat from your pump properly.

While these problems are common causes of hydraulic pump overheating, pumps can overheat for numerous additional reasons.

Overheating Solutions

Once your hydraulic pump beings overheating, you need to find the cause of the problem and repair it. That way, your pump can begin operating within its ideal temperature range again.

If your pump overheats due to fluid contamination, then either remove all contaminants from existing fluid or remove the current contaminated fluid from the system and add fresh fluid. Be sure to filter all fresh hydraulic fluid before you add it to your system because even this fresh fluid can contain contaminants. Also, replace your fluid filters on a regular basis to prevent the overheating that can occur when these filters become blocked with debris.

If air has entered your system through leaky seals and fittings, then have a hydraulic system repair expert inspect and replace or tighten these fittings. Have a hydraulic system repair expert also look at heat exchanger damage to determine if the exchanger needs repairing or replacing.

Finally, be sure to check your system's reservoir fluid level on a regular basis. Add new fluid when necessary to help this reservoir perform its important task of helping to keep your pump cool.

Your hydraulic pump should always operate within its ideal temperature range. If your pump is running hot, then contact the hydraulic pump experts at Quad Fluid Dynamics, Inc., for hydraulic pump diagnosis and repair today.

Maintenance Tips to Avoid CNC Machine Repair

Tue, 08 Dec 2020 22:27:03 GMT

A CNC machine can transform your business. The right setup can help you transition your manual work into an automated process that will lead to higher productivity and efficiency across the board. You'll also deliver products with greater consistency to your customers, with fewer deviations in a build's final quality.

But CNC machines require routine maintenance and care if you want to avoid any interruption to your daily operations. A shop without a regular maintenance schedule for its CNC machinery might need serious repairs later. For best results, you should likely partner with a local firm that offers CNC service and repair. For now, use these tips to keep your CNC machines running.

Keep a Checklist

Create good habits around CNC machine inspection and maintenance by making every employee go down a checklist before beginning operation for the day. Is the machine in good condition? Do any parts look faulty or need a tune-up? Do all safety mechanisms work properly? Following along with a daily checklist will help you find and fix small issues before they turn into big problems.

Keep It Clean

Depending on what kind of materials your CNC machine works with, some debris or grease could be in the area after a production run is finished. Make every employee responsible for cleaning the work area after every run and before starting up the machine again. A clean work area will also ensure that no debris gets into the wrong spot during operation, potentially damaging your CNC machine.

Keep It Lubricated

CNC machines have lots of moving parts and plenty of places where metal brushes up against metal. These metal parts usually need proper lubrication in order to reduce wear and tear. A CNC machine without proper lubrication will have one or more parts likely suffer a decrease in life expectancy, eventually leading to a large repair or replacement bill.

Keep Some Downtime on the Schedule for Inspection

One of the key benefits of installing a CNC machine is that you can dramatically increase your output thanks to the automation. But you should give your CNC machine a break just as you would a human worker working with manual equipment. Running your machines nonstop will leave no time for a full inspection of your equipment.

Hopefully, you have each employee following along with a daily checklist, but you should also plan to shut down all of your CNC machines for a more in-depth inspection at least once a month. If you aren't familiar enough with the inner workings of the machines to conduct this review yourself, contact a local professional for help.

Keep Mission Critical Spare Parts on Hand

For best results, you may want to partner with a local CNC service firm to ensure that your company always has important spare parts available. You may have some parts you are able to quickly replace yourself without having to wait for a CNC service to get out to your business. This will allow you to get all machines back up and running and keep production moving along.

Keep Communication Open With Employees

Finally, create a system for your employees to report potential issues in need of maintenance. If an employee notices an issue on the daily checklist, they should have a specific manager they go to who has to give the all clear before the machine can begin work for the day.

Your company's CNC machines can boost productivity and the overall quality of the products you create. But regular maintenance is key if you want to keep your CNC machines operational and out of the repair shop. Proper lubrication and regular inspections can keep things working and allow you to detect potential problems before they develop into serious issues.

At Quad Fluid Dynamics, Inc., we have years of experience servicing CNC machines like yours. We understand that a non-operational machine lowers your productivity and harms your bottom line and will work to get you back up and running quickly. Contact us today for more information.

Hydraulic Pump Aeration Versus Cavitation: What's the Difference?

Fri, 13 Nov 2020 13:14:54 GMT

Most modern hydraulic pumps are reliable, robust pieces of equipment that will withstand years of constant service. However, any hydraulic pump can suffer from mechanical issues. Aeration and cavitation are two serious problems that can affect a hydraulic pump, and either problem can cause serious damage if the issue is ignored.

However, it can be difficult to figure out if a malfunctioning pump is suffering from aeration or cavitation, as the two problems tend to produce similar symptoms. Despite these similarities, aeration and cavitation have different causes and require different solutions, so knowing the difference between the two problems is vitally important knowledge for any hydraulic pump user.

What Is Hydraulic Pump Aeration?

All hydraulic pumps contain a small amount of air, which provides space for the pump's hydraulic fluid to expand into as it heats up. However, excessive amounts of air in a hydraulic system can cause serious problems.

Aeration in hydraulic pumps occurs when air is drawn into the pump's hydraulic fluid supply. Air can infiltrate your system through perished pump seals, damaged pipe connectors, leaking suction lines, and other forms of damage. This unwanted air mixes with and dissolves into the hydraulic fluid supply.

Hydraulic fluid that has been contaminated by exposure to air loses many of its functional properties. For example, hydraulic fluid containing excess air cannot conduct heat as efficiently, so aeration can cause rapid overheating in affected pumps and other hydraulic systems. Serious aeration can also impede the pump's stroke cycle, causing a significant drop in usable power.

What Is Hydraulic Pump Cavitation?

For a hydraulic pump to function properly, the flow of fluid from the pump's reservoir to the pump itself must remain constant and unimpeded. If this flow speeds up or slows down for any reason (such as improper pressure settings or a block in the suction line), this can lead to a potentially catastrophic problem known as cavitation.

When a running hydraulic pump does not receive hydraulic fluid at the proper rate, fluid pressure in the pump's suction line can drop dramatically. This causes the formation of bubbles inside the hydraulic fluid, which contain air and vaporized hydraulic fluid. These bubbles subsequently collapse, creating an incredible amount of force and heat.

The shockwaves created by these imploding bubbles can do an incredible amount of damage to a hydraulic pump in a short space of time. The pump's impellers and interior surfaces tend to be particularly badly affected by cavitation, and a pump that has suffered from extensive cavitation may need a complete rebuild before it can be used again.

How Can You Tell the Difference Between Cavitation and Aeration?

While cavitation and aeration have different causes, they can produce similar problems, making proper diagnosis difficult. High hydraulic fluid temperatures, lowered pumping rates, and visibly damaged valve seals can all be caused by either cavitation or aeration.

Generally, the easiest way to tell the difference is by listening to the malfunctioning pump, as both types of problem usually produce distinct noises. A cavitating pump tends to produce a steady, rhythmic pattern of knocking or whining noises. Unusual noises produced by aeration are more erratic and random and tend to sound more like rattling than knocking.

However, it is important to note that cavitation and aeration are not mutually exclusive problems, and a poorly maintained hydraulic pump may suffer from both problems simultaneously. Combined aeration and cavitation can lead to a particularly damaging form of cavitation, known as gaseous cavitation.

If your hydraulic pump is suffering from any signs of cavitation or aeration, calling in a professional hydraulic repair service is usually the fastest way to get to the bottom of the problem. These services have access to specialized testing tools and equipment that can quickly detect cavitation and aeration and will be able to provide rapid and effective solutions.

If your hydraulic pumping system is not functioning as it should, and you think cavitation or aeration may be the cause, contact the hydraulic experts at Quad Fluid Dynamics, Inc. , for professional advice.

3 Reasons Why Your Hydraulic Pump Is Unusually Noisy

Mon, 19 Oct 2020 13:50:06 GMT

Every hydraulic pump makes some noise. If all is well with a pump, then this noise stays more or less the same. However, if something goes wrong with the pump or its connected system parts, then you may start to hear sounds that you haven't heard before.

For example, the pump may suddenly run more noisily than it usually does. It may make whistling, whining, clicking, or banging sounds.

Why do pumps sometimes make unusual noises?

1. Fluid Flow Problems

The fluid that flows through your system needs to move at a smooth and even rate. The pump has to deliver the fluid at a specific flow for things to work.

If something prevents the fluid from achieving and maintaining its optimum flow, then your pump may start to make unusual noises. For example, you may hear a high-pitched whine coming from the pump. This can be a constant or intermittent sound.

If your pump whines constantly, then you may have a cavitation problem. Here, the pump can't deliver its fluid at the right volume or rate. There isn't enough fluid coming through the pump's suction line.

Cavitation is often caused by a blockage. For example, you may have a clogged or dirty line, filter, strainer, or vent that prevents the fluid from flowing at its full rate. Or, the fluid may be too viscous to run smoothly.

In some cases, this is a sign that your pump's motor is on the wrong setting. So, the pump itself is working at the wrong speed to create the right flow.

If you hear intermittent whining, then you may have air in your fluid. Sometimes, a leak in your suction line or a seal allows air to get inside and into the fluid. The air creates bubbles in the fluid, which effectively pop as they move. If you have aeration problems, then you may also hear a rattling noise that sounds like stones banging against each other.

2. Malfunctioning Parts

A hydraulic pump might get noisy if one of its parts or connections has a problem. A faulty or failing pressure control, bearing, valve, seal, or coupling can make a noise you haven't heard before.

For example, if a relief valve stops working correctly and opens up permanently or too often, then the valve might make hissing sounds. A gummed up valve might make loud noises as it opens and closes, as it can't operate smoothly.

In some cases, you may hear vibrating clunks as your pump works if you have a problem with a connecting pipe. A loose seal or connector might allow the pipe to move. It then passes vibrations along to the pump itself.

3. Pump Failure

While some noise problems are easy to fix, some are a sign that your pump is close to the end of its working life. Sometimes, this is due to natural wear, usage, and age. However, in some cases, minor problems cause more widespread damage if you don't fix them quickly.

For example, if you've had cavitation problems for a while, then your system may not have been getting the lubrication it needs; it may have overheated regularly. Even if you fix the cavitation issue, you may be left with a damaged pump that needs a more significant repair, rebuild, or replacement.

So, while new sounds or an increase in operating noise don't necessarily mean that you have a serious pump problem, you should investigate any unusual noise. Typically, this is a sign that something isn't working right.

A minor problem in your system could go on to cause significant damage. For an expert diagnosis, contact Quad Fluid Dynamics, Inc. Our hydraulic pump repair and rebuild service will get your pump running smoothly and efficiently again.

An Easy Guide to Hydraulics

Thu, 10 Sep 2020 19:33:47 GMT

Hydraulics, though a complex word, works on simple principles. We use these principles often in our daily life and activities. Below are some the basic principles of hydraulics explained in terms of two common objects: a water gun and a garden hose.

The System

Imagine a water gun. It has a simple mechanism - pull the trigger and water comes out. However, these devices only work because of basic hydraulics. The pressure from your finger on the trigger of the gun puts pressure on the water inside it. Because water does not condense, it comes out the other end.

The faster you pull the trigger, the faster the water comes out. This is described by Pascal's law, which states that there is a direct correlation between the amount of pressure you put on one end of your water gun and the pressure of the water leaving the other.

Now imagine a water hose. The hose pump applies pressure to water at a constant rate, and the water leaves the hose at a constant velocity. However, you can change this velocity by putting your thumb over the hose.

By putting your thumb over the hose, you reduce the size of the opening that the water comes out of. The hose pump is still applying pressure to the water, so the water must find somewhere to go. Therefore, the water leaves the hose at a higher velocity.

Based on these two examples, we know that there is a correlation between pressure and velocity of incompressible liquids.

Industrial hydraulic systems are like backwards hoses. Instead of going from a large, low velocity stream to a smaller, faster one, these systems use highly pressurized streams of liquid to move larger objects at a slower rate.

The Pump

A hydraulic pump is just one part of an entire hydraulic system. The purpose of a pump is to convert a slow stream of liquid to a stream with high pressure and high velocity.

There are two main types of hydraulic pumps: hydrodynamic (nonpositive) and hydrostatic (positive displacement).

Hydrodynamic Pumps

Hydrodynamic pumps rely on standard hydraulic principles, but they are not very efficient. Each pump rotation gives a variable pressure, and there is a lot of slippage - making the system less powerful.

Nonpositive pumps are like water guns. If you plug one end of a water gun, it doesn't explode. But the system is too weak to hold the seal against mounting pressure. Instead, water leaks out the trigger end. This brings the pressure back to zero, until you take your finger off the nozzle.

Hydrostatic Pumps

A hydrostatic pump, on the other hand, has an input and output end. The pump mechanism is placed in a vacuum. Water comes in through one end, drawn in by the low pressure of the system. After enough water has entered, the input end seals off to prevent any slippage. Pressure grows until the piston is released and liquid flows out at a high velocity through the output end.

Hydrostatic pumps are more powerful, yet more dangerous. A hydrostatic pump seals off each side, reducing slippage to almost zero. Each pump rotation gives a constant pressure, which is useful on industrial machines. However, a hydrostatic pump is like a hose. If one end is blocked off, pressure rises until the system explodes.

The same principles that make water guns and garden hoses function are used on a much larger scale in industrial machines. No matter the size, a hydraulic system is based on Pascal's principal. Pressure and velocity on one end of an incompressible liquid is directly proportional to the pressure and velocity on the other.

5 Specialty Hydraulic Shop Tools

Wed, 19 Aug 2020 15:59:39 GMT

A hydraulic machine shop is a specialty workshop that focuses on creating high-precision metal components for a wide range of industries. The main attraction, naturally, is the hydraulic press, an incredibly powerful and complex tool that has dozens of unique applications. Having access to a hydraulic press allows metallurgists to perform unique and useful tasks that would otherwise be impossible.

However, a quality hydraulic shop has many other tools that can expand the scope of what the metallurgists can accomplish. In addition to more common tools, such as arc welders, band saws, and drills, many shops enjoy access to specialty machinery. Read on to learn about five of the unique and useful tools that well-equipped hydraulic shops should choose to invest in.

1. CAD Workstations

A computer-assisted design (CAD) workstation is a series of computers that are connected to high-precision machining tools. Sheet metal is placed on the workstation, and instead of using hand tools to directly machine the metal, you use a computer program to dictate the exact cuts and grinds to be made, and an automated system does the rest.

CAD workstations allow metallurgists to achieve extreme precision quickly and easily. If you need a large volume of precise metal parts, a worker with a CAD workstation can get them done in a fraction of the time it would take to process the parts traditionally.

2. Lathes

You may already be familiar with wood lathes, the tools that spin wood around rapidly and allow you to make things like cups, bowls, and pens very quickly. Did you know that metal lathes exist as well? A tool like a computerized numerical control (CNC) lathe can allow you to create circular parts of the exact diameter you need, and vertical turning lathes provide immense power to create large parts.

3. Grinders

A grinder is tool that spins a disc at rapid speeds. When you press the disc against the metal, you shave off tiny layers of metal, allowing you to get a smooth finish and achieve a perfectly level edge. Angle grinders are great for small jobs, and surface grinders are more heavy-duty and allow you to guarantee a flat finish.

Inside diameter (ID) grinders allow you to remove metal from the inside of circular pieces, such as pipes. Conversely, outside diameter (OD) grinders shave off the outer layer. In short, every grinder is designed to remove some mass from a piece of metal, bit by bit, until it's exactly how you want it.

4. Borers

The borer family of tools is essentially comprised of large, extra-powerful drills. They're designed to create precise holes that extend deep into metal parts. A jig borer creates small lead holes that will then become the center of larger holes. These larger holes are often made by a horizontal boring mill, a large machine that can drill clear through any metal surface.

Due to the sheer power needed to create large holes through metal, boring mills are large and expensive. Nevertheless, their utility cannot be ignored, and most serious metal shops have access to one.

5. Lapping Machines

Towards the end of the project, metallurgists will employ a lapping machine to create truly flattened and polished surfaces. A lapping machine employs a liquid slurry made from small abrasive bits combined with water or oil. It applies the slurry to the surface, and then uses a relatively soft grinding wheel to scour the surface of the metal into an incredibly smooth, flat surface.

Understanding Hydraulic Pump Fluid Contamination

Wed, 15 Jul 2020 19:15:52 GMT

Your hydraulic pump performs an important function. In fact, if you're like most industrial businesses, you rely on your pump daily. For this reason, guarding against hydraulic pump failure is crucial. Fluid contamination is one of the main causes of failure in hydraulic systems. To avoid contamination, you should understand contamination and how to spot and avoid it. Here's what to know.

Fluid Contamination

Particle contamination is when small or microscopic material particles make their way into your fluid. Common particle contaminants are small metal particles from the pump or surrounding machines, dirt, human skin, and hair flakes. It might not seem like these small particles can cause damage, but they definitely do, especially when they build up in the fluid.

Water can also be a fluid contaminant. Too much water in the fluid can lead the pump and system to rust and to various operation problems, including clogs and reduced efficiency. If fluid contamination gets too bad, your entire system could end up damaged.

The good news is that there are many ways to guard against fluid contamination and its damaging effects.

Inline Filtration

One of the best ways to protect your hydraulic fluid from contamination is to install an inline filtration system. These systems are especially good at helping you avoid particle contamination because they catch particles before they have the chance to enter the fluid area. 

The key is to choose the right size and design of filter for your specific pump. If you don't choose carefully, these filters can cause pressure loss and other operation problems. If you're unclear on which exact filtration system to buy, get some professional advice before you make a selection.

Contamination Monitors

In addition to a filtration system, a contamination monitor can be a great help in maintaining the quality and integrity of your hydraulic fluid. Many different types and styles of monitors exist, but they all have one important function in common: measuring particulate levels and water concentration. 

For best results, you should buy the most sensitive monitor that you can find. Also, keep in mind that some monitors also come equipped with liquid purification devices, some of which will even go to work automatically when they detect overly high levels of particles or water.

While an extra charge is typically associated with this feature, it is often worth investing in. With this add-on, not only will you know when a problem has developed, but you'll also be able to fix it right away. The sooner you get your fluid levels correct, the less chance there will be of damage to your system.

External Purification

While an internal purification system is definitely nice to have, especially if you have one that attaches to your monitor, sometimes you may need to filter your fluid externally.

This is even truer in cases where contamination levels are high. In these cases, you will need to remove the fluid from the system, remove all contaminants via external purification - such as with a free-standing filter designed for this purpose - and then replace the fluid. Your other option is to throw out the old fluid and replace it with new fluid, but this can get expensive. It's a good idea to have an external purification system available for use if and when it's needed.

Fluid contamination can be a real problem. But if you're aware of the problem and have measures in place to fix it if it does occur, you and your system will fare much better.

5 Unique Uses for a Hydraulic Press

Wed, 17 Jun 2020 17:47:45 GMT

A hydraulic press is a piece of industrial machinery that uses a hydraulic cylinder to create huge amounts of compressive force. These machines are commonly used in the manufacturing industry, including in the creation of car and plane parts. You'll often find a hydraulic press in a plant or shop that works with metal.

Hydraulic presses are useful in a wide range of industries. Read on to learn about five of the lesser-known uses for hydraulic presses.

1. Making Ceramics

Many people imagine the creation of ceramics as artisanal work that requires a delicate hand - far from the sheer power that a hydraulic press provides. Nevertheless, many ceramics professionals find great success with presses. The hydraulic press is fixed with a die on each cylinder, and the press forms the clay into any shape you want, such as plates, mugs, and ornaments.

A hydraulic press allows ceramic products to be created far more quickly and consistently than manual work would allow. Despite this, you still have plenty of artistic control over each product, such as introducing unique factors in the paint, details, and glaze.

2. Blacksmithing

Blacksmiths are artisans who create complex works from iron and steel. This process involves heating up the metal in a forge, then hammering it hundreds or even thousands of times to shape it and increase its strength. A hydraulic press can strike with the force of a hammer repeatedly with no effort on the part of the smith.

This streamlines the process considerably, allowing the smith to create more products with less effort. Since the cylinder strikes in the same spot with the same power every time, it's also more reliable and precise than manual hammering.

3. Compacting Daily Essentials

Have you ever wondered how makeup powders are packed into their containers? The answer is through the use of a hydraulic press. By applying a large amount of force, the makeup is compressed into a small block, sturdy enough to hold its shape and loose enough to be picked up by a makeup brush.

Additionally, the medical industry uses hydraulic presses in the creation of pills. Compressed powder will stay whole as it is swallowed, but it will easily dissolve once it reaches the digestive tract.

The food industry compresses foods such as meat and cheese before packaging. This not only makes the food easier to pack and transport, but it also increases shelf life by forcing out air, denying microscopic life the chance to thrive.

4. Waste Disposal

A hydraulic press can help you recycle specialty waste products. In the case of an oil filter, a press can compress it to a fraction of its original size while squeezing out all remaining oil, allowing you to reuse or dispose of it separately. In more general circumstances, a random selection of run-of-the-mill junk can be compressed into a convenient cube for easy disposal.

5. Creating Viral Videos

Hydraulic press videos attract many viewers on video sharing sites and social media platforms. These videos typically involve taking a household product, such as a toy or a fruit, and crushing it in a hydraulic press. There's something strangely satisfying about seeing a familiar object being destroyed in such a dramatic way.

Many objects behave unexpectedly in a hydraulic press. Pads of sticky notes crack apart like bricks, candles blast through small openings like streamers, and metal kitchen utensils are turned into modern art. These videos can gain a lot of traction online, granting more traffic to your web page.

Are you interested in purchasing a custom hydraulic press for personal or professional use? Come to Quad Fluid Dynamics, Inc., today. We'll create a hydraulic press that fits your exact needs, so don't hesitate to reach out.

Understanding Servo Motors and How to Choose the Best One

Thu, 07 May 2020 19:10:20 GMT

Servo motors have been in the industry for long and are used in many different applications. Servo motors offer advanced and precise control over motion. Using the right servo motor provides high flexibility, speed, and accuracy. Though these drives are small, they provide high efficiency.

If you wish to use a servo motor in your company, then you need to understand how they work. That way, you can choose the one most ideal for your specific application. Choosing the wrong type of servo causes reduced accuracy and performance.

When Should You Use a Servo Motor?

The best use of servo motors is in the designing and manufacturing of robots. Some applications that use servos include conveyor belts and automatic door openers. 

Servo drives can control the positioning of surfaces in the manufacturing industry. In the pharmaceutical and food industries, servos help in resisting harsh environments. The applications of servos are endless. 

Types of Servo Motors

Servo drives have two main types: linear and rotary servo motors.

Rotary Servo Motor

When most people think of servo drives, they are mostly thinking of a rotary servo. There are various kinds of rotary motors:

Permanent magnets
AC servo motors
Brush DC servo motor
Stepper servo motor
Brushless DC servo motor
Synchronous servo motor

Rotary servo motors use screw threads to change their motion into linear motion.

Linear Servo Motor

The rotor of the linear servo drive is on the inside while the coils are outside. The reduced prices in servo motors have led to an increase in the use of the linear servos.

How Can You Choose the Best Servo Motor?

You should consider different elements to find the best servo model. For instance, you may need a standard size servo when moving a robot compared to a small size required to run a toy.

The Size of the Motor

The process of calculating and choosing the ideal servo motor is sizing. During sizing, you need to examine the relationship between speed and torque. These vital formulations help you determine the servo size you need. The payload weight, distance, and speed of the cycle are elements you need to factor in your calculations.

Torque refers to the muscle or strength it takes to rotate the machine. The torque is the most challenging part to calculate. You can find the formula for calculating torque from various online sources. 

The Gear Ratio

Most servo motors have gears. Direct drive servo motors made people consider geared motors as traditional. Gears, however, can help increase torque capabilities in drives with lower pole count. The servo motor turns the driver gear until it gets to the gear closest to the payload. The number of teeth in any pair of gears makes up the  gear ratio . The ratio is important in calculating the servo drive torque.

The Regeneration Energy Processing

Analyze how much regenerative energy the motor and the load are creating. You should then choose a servo that can handle this regenerative energy. If the drive is not moving in the same direction as the torque applied, the energy regenerates back to the amplifier. That is because the generator and servo drives have the same basic designs.

The Control System Requirements

A servo always has a feedback device. The feedback device needs to have the perfect resolution. The positioning tolerance needs to match the precision of the resolution. The signal from the feedback device also needs to match the amplifier.

Understanding the information given will help you find a suitable servo motor. The best thing about servo drives is that you can customize them to suit your needs.

If you are looking to buy servo motor drives to use in your firm, then  contact Quad Fluid Dynamics, Inc . Our experts will ensure you get the most suitable servo drive.

Irrigation, Aqueducts, and Mills: Ancient Precursors to Modern Hydraulics

Mon, 20 Apr 2020 19:47:26 GMT

When you think of hydraulics, you likely think of heavy machinery, like that used in mining and manufacturing applications. However, while these industries use hydraulic equipment, hydraulics itself is a branch of science that seeks to understand and use liquid in motion.

Many people trace the beginnings of modern hydraulics to Blaise Pascal, a French physicist. In 1648, he discovered Pascal's law, which states that pressure on a confined fluid will transmit equally in all directions throughout the fluid. This discovery made possible the complex, precise, and powerful equipment we use every day.

However, people have used hydraulics for thousands of years. Learn more about some of the ancient precursors to the modern hydraulics used today.

Shushtar Historical Hydraulic System

In Persia, located in modern-day Iran, the Shushtar Historical Hydraulic System spreads over 594 acres , making it a massive feat of engineering for its time. Parts of the system may be from the time of Darius the Great, around 500 BCE, though much of it was built in the third century AD.

The system contains dams, canals, and tunnels, and it made farming possible for a wide swath of land that would otherwise have been too dry. Additionally, the hydraulics system supported watermills, carefully placed and surrounded by safeguards to ensure that they wouldn't be damaged by a sudden influx of water.

The center of the system is Salasel Castel, which includes a tower to measure the water level to enable control of the flow throughout the system. Today, the Shushtar Historical Hydraulic System is an UNESCO World Heritage Site based on its ingenuity and complexity.

Roman Aqueducts

The Roman Empire was famous for its use of aqueducts, which are channels built to carry water from its source to a distribution point. While many ancient and modern civilizations used aqueducts, the Romans constructed them extensively, and many of their distinctive bridged aqueducts still stand today.

Roman engineers designed aqueducts based on their understanding of how gravity influences water: they used steeper gradients and narrower waterways to make the water flow faster when needed, and they followed the contours of the land when building. Additionally, they used devices like sedimentation tanks to filter the water and sluices to regulate the supply.

These aqueducts provided water for everyday use in towns and cities, but they did much more besides that. They carried water for public baths and latrines, and workers used the running water to power milling and mining operations. Additionally, the water provided irrigation for farms and gardens.

Muslim-World Mills

During the Islamic Golden Age, engineers in the Muslim world used hydropower extensively. While Europe used mills mainly to grind grain, Muslim world industry used mills for fulling (a step for producing wool clothing), making paper, cutting lumber, building ships, creating stamps, and manufacturing steel.

Additionally, these societies pioneered using dams as a storable power source, something we still do today. While they didn't use dams to produce electricity, they used the water stored in dams to power mills effectively and reliably.

Hydraulics powered parts of the ancient world thanks to their scientific understanding of water's movement, and we've been able to build on their work for centuries to create today's complex machinery. Today, hydraulic machinery relies on fluids like oils instead of water, and hydraulic equipment is both ubiquitous and highly specialized.

3 Problems That Can Plague Your Hydraulic Fluid

Wed, 18 Mar 2020 16:36:18 GMT

Hydraulic fluid is the lifeblood of your hydraulic system. This fluid performs many different functions as it travels throughout the hydraulic system, including lubricating moving parts and preventing corroding hydraulic components.

The quality of your hydraulic fluid can have a direct impact on the performance and durability of your hydraulic system over time. Anything that compromises a hydraulic fluid's ability to perform its assigned duties efficiently could lead to a major mechanical problem down the road.

Be aware of common problems that can plague your hydraulic fluid so that you can correct these issues before they compromise the health of your hydraulic system as a whole.

1. Contamination

A major problem that can wreak havoc on the performance of your hydraulic system is contaminated fluid. Air and water are two of the most common contaminants that find their way into your hydraulic fluid supply.

Water contamination will cause your hydraulic fluid to take on a milky appearance and impacts the lubricating properties of the fluid. Water in your hydraulic fluid could also limit the fluid's ability to prevent corrosion.

Air contamination can be just as detrimental to the performance of your hydraulic system. The air causes the hydraulic fluid to become more elastic, and it cannot be compressed properly. Hydraulic fluid contaminated with air will have a foamy appearance.

If you see signs of either air or water contamination in your hydraulic fluid, flush your system quickly to avoid lasting damage.

2. Cavitation

Cavitation is another problem that can affect your hydraulic fluid. Although it sounds like a complex issue, cavitation is actually a simple process.

Cavitation occurs when a rapid change happens in hydraulic fluid pressure. This rapid change causes bubbles, referred to as cavities, to form within the fluid. Minute shock waves are emitted whenever these cavities collapse. The metal components close to these collapsing bubbles can sustain serious damage as a result of exposure to the shock waves.

If you notice a sudden increase in noise during the operation of your hydraulic system or feel an increase in vibration, cavitation may be to blame. You can combat cavitation by reducing motor speed, lowering pump temperature, and installing an impeller inducer.

3. Aging

The hydraulic fluid that runs through your system can become less viable as time goes on. As the fluid ages, it loses its ability to perform the vital tasks required to keep your hydraulic system functioning properly.

Aging occurs when the chemical additives that enhance the performance of a hydraulic fluid begin to break down. As the additives become less effective, your hydraulic fluid becomes less effective as well.

Only buy as much hydraulic fluid as you need to fill your system so that you do not have to stockpile any extra. This will help you avoid using aging fluid in your system. You should also schedule routine fluid flushes to remove hydraulic fluid from your system before aging compromises its efficacy.

You take good care of your hydraulic equipment so that you do not experience any unplanned shutdowns or production delays. Dedicate the same level of care to your hydraulic fluid. Contamination, cavitation, and aging are all problems that originate within your hydraulic fluid but can eventually cause serious system failure if not addressed in a timely manner.

At Quad Fluid Dynamics, Inc., we have the expertise needed to repair any damage to your hydraulic components from compromised fluids. Contact us today to learn more about managing your hydraulic fluids effectively in the future. We look forward to speaking with you, answering all your questions and concerns, and meeting your hydraulic fluid and equipment needs.

3 Valid Reasons to Choose a Hydraulic Rebuild Over Replacement

Fri, 07 Feb 2020 18:13:59 GMT

Hydraulic equipment bears the bulk of the work in many industrial settings. Any time your hydraulic equipment malfunctions, you could lose out on valuable production time.

You have no room for delays when getting your hydraulic equipment running properly once again, so you will need to decide if you want to invest in a rebuild or a replacement of the broken component as quickly as possible.

Hydraulic rebuilds can offer a number of advantages that your company may find beneficial over time.

1. Cost

Perhaps the most attractive reason to opt for a rebuild rather than a replacement when your hydraulic equipment fails is cost. In fact, a rebuild can cost a fraction of the price of replacing a hydraulic component completely. This is because hydraulic failure is usually from damage to a single element of a major component.

For example, a hydraulic cylinder can fail because of a faulty seal or a ruptured shaft. Only these small elements need replacing when completing a rebuild, which helps to keep costs to a minimum.

It does not make sense to replace an entire hydraulic component because of a few faulty elements - especially when these elements can easily be replaced.

2. Time

Time is money in any industry. The longer your hydraulic equipment is down due to a faulty component, the more money your company misses out on. Rebuilt hydraulic components have a much shorter lead time than either replacement parts or a new component.

You may have to spend days waiting for a replacement part to arrive or waiting for a technician to come install a new hydraulic component to get your machines back up and running properly. An experienced professional can rebuild the damaged hydraulic component immediately.

When paired with proper maintenance, rebuilt hydraulic equipment will minimize the amount of downtime your company experiences as a result of hydraulic failures.

3. Environmental Impact

More and more companies in the industrial sector have taken note of the impact their day-to-day activities has on the environment. Consumers want companies to be conscious and proactive when protecting finite resources.

A hydraulic rebuild can help your company significantly decrease its environmental impact by reducing the amount of resources needed to keep important hydraulic equipment running regularly.

The process of creating a new hydraulic component requires the smelting of iron, the processing of this iron into steel, the use of metals for ancillary elements, and the use of fossil fuels to ship finished hydraulic components to their final destination.

A rebuilt hydraulic component will typically feature elements that are reconditioned. The amount of energy and resources needed to recondition a part pales in comparison with the resources used to generate the product from scratch.

All of these factors combined help to make rebuilt hydraulic components the greener choice for any company that relies on heavy equipment. You can use the fact that you opt to rebuild rather than replace your hydraulic components as a marketing point to help attract new customers to your business.

A professional and thorough hydraulic rebuild can keep your company's heavy machinery functioning efficiently. You will be able to significantly cut your operating costs by reducing downtime when you opt to invest in rebuilt components. Hydraulic rebuilds can also reduce your company's environmental impact and make your products more attractive to eco-conscious consumers.

Contact Quad Fluid Dynamics, Inc., if you are ready to explore the benefits a hydraulic rebuild can offer your company. We can troubleshoot, recondition, and maintain your hydraulic equipment to make your heavy machinery more dependable in the future. We look forward to answering all of your questions.

Shift Your Hydraulic Contamination Control Practices From Basic to Best

Fri, 03 Jan 2020 19:00:57 GMT

Basic hydraulic filtration applications revolve around fluid cleanliness and preventative maintenance for good machinery uptime. However, moving beyond basic foundations can launch hydraulic contamination control into a greater realm of operation. For optimized system performance, fewer maintenance problems, and reduced operating costs, try shifting from basic contamination control practices to these best practices.

Fluid Cleanliness

Basic foundations of fluid cleanliness rely on several key practices. Filter new fluid before it enters a system reservoir and each time a component is replaced or repairs are performed.

However, a more in-depth consideration for fluid cleanliness involves frequent tests for fluid contamination. Higher operation pressures in high-performance hydraulic equipment demands more than just periodic lab analysis of fluid. Professional lab tests are usually only reserved for critical equipment and can be costly. Plus, results can take time to complete, during which hydraulic equipment must still operate.

Portable testing units allow users to test fluid cleanliness while a machine is still in operation. Testing can occur much more frequently, and on additional equipment deemed less critical. Results are instantaneous. In addition to particle counting, some units come equipped with software that can analyze wear debris to enhance maintenance programs.

Filter Maintenance

Examine filters and replace them before bypass mode based on operating conditions and not just recommended timetables, which can encourage waste and contamination.

Enhance filter performance and simplify filter maintenance by equipping filters with differential pressure gauges or switches. Choose multiple pressure gauges over single gauges, which better measure particles during fluctuations and are simpler to read and understand. Users can gain a more clear understanding of how much dirt, if any, exists inside a filter element simply by comparing the inlet pressure to the outlet pressure.

Additionally, users can receive an audible or visible warning before a filter enters bypass mode when a differential switch is hard-wired to a light or alarm.

Filter Location

Filters perform best on system return sides, where contamination within the system can be caught by a return line filter . Any flow restriction is less likely to impact important valves, motors, and pumps. Avoid placing filters where they restrict flow, such as on drain lines of motors and piston pumps, or at pump inlets.

Sometimes reservoirs accumulate contamination from external sources or over the course of operation. Add an off-line kidney loop filtration system to better filter the reservoir and help filters last longer. Kidney loop systems act as an independent filtration unit with a dedicated motor, pump, and filter. A kidney loop system can run continuously or as needed, depending on operation requirements.

An independent filtration system like the kidney loop system offers several advantages:

Uses fewer filters because it does not have to operate at high pressure.
Does not impact system operation during shut down for filter maintenance.
Uses less-fine filters because it continually cleans fluid.
Will not release trapped debris back into system fluid due to high efficiency.

Kidney loop systems are supplemental inline filters only and must match the application. Flow rates can vary, and the right system depends on reservoir size and fluid amounts. Users can choose additional functions like contamination sensors that detect high levels of debris or heaters and coolers that help a system better adapt to equipment that operates in different temperatures.

Sometimes a simple pump rebuild can help change a contamination equation. Even better, Quad Fluid Dynamics, Inc., can design a custom hydraulic system to help you implement the best maintenance practices for contamination control. Talk to our design experts today about how a custom system can work for you and your business to help lessen damaging and costly contamination occurrences.

7 Ways to Reduce Hydraulic Pump Energy Consumption

Fri, 06 Dec 2019 20:14:34 GMT

Hydraulic pumps are essential pieces of equipment for many industrial and manufacturing operations. Any inefficiencies in hydraulic pump operations significantly increase overhead costs for facilities and cut into a company's bottom line.

Fortunately, you can optimize hydraulic pump energy consumption in numerous ways. The following are seven ways to reduce hydraulic pump energy consumption.

1. Properly Sizing the Pump

Pump size and motor size are essential considerations when optimizing energy consumption. Sizing issues often occur when engineers try to bring in a safety factor at the design stage. This leads to pump oversizing issues that increase maintenance needs and energy consumption.

2. Selecting the Right Pump Type for the Application

Numerous factors distinguish individual pumps. Industrial and manufacturing facilities must carefully analyze factors such as drive type, needed power, ancillary equipment availability, speed, and mechanical seal type of individual pumps.

Manufacturing and industrial operations must match up these factors of hydraulic pumps to be optimal for the particular application. Determining the right pump type requires careful and thorough communication and collaboration between the manufacturer of the pump and the specifying engineer in charge of the project in question.

3. Not Allowing Excessive System Pressure Drop

Keep system pressure drop under control to avoid energy waste. If system pressure drop is a problem in your hydraulic pump equipment, you can reduce it if you resize piping. Incorrectly sized piping means that energy loss occurs due to friction between opposed ends of the piping.

Other factors that influence system pressure drop are surface characteristics of the pipe, properties of the hydraulic fluid, flow rate, and the diameter of the piping. Making adjustments to these factors sometimes resolves system pressure drop problems.

4. Using Multiple Pumps

Multiple pumps working together in tandem are often more energy-efficient than a single pump. Consider the implementation of a multiple pump parallel system if you're concerned with elevated energy consumption levels in relation to your hydraulic pumps.

Remember that individual pumps should run separately and not concurrently in a multiple pump parallel system to maximize energy efficiency. However, in certain situations, running multiple pumps at the same time is optimal depending on the flow requirements of the application in question.

5. Trimming the Impeller

You can trim the impeller pump of a hydraulic pump to prevent the loss of energy from throttling issues that have to do with the control valves.

Determine the extent to which you should trim the impeller by analyzing both affinity rules and pump curves. These factors provide insights on analyzing how successful impeller trimming has been in optimizing energy consumption.

6. Implementing Control Valves

Control valve implementation is essential for keeping both pressure and flow closely under control. Control valves are helpful for preventing energy loss caused by irrigation systems, for example.

Generally, control valves regulate bypassing and throttling flow. Optimize energy consumption by keeping excess pressure to a minimum through bypass of flow to a reservoir.

7. Performing Key Maintenance

Keeping up with hydraulic pump maintenance is essential to ensure continued energy efficiency. During maintenance procedures, technicians locate any deterioration that detracts from efficiency.

Examples of deterioration that unnecessarily increases energy consumption include rotor erosion and wear ring erosion. Maintenance involves applying lubrication that reduces friction, which is a huge cause of energy inefficiencies.

Another efficiency issue routine maintenance takes care of is contamination problems. Routine maintenance reduces equipment malfunctions that lead to downtime. In addition to energy inefficiency, downtime is another costly issue for industrial and manufacturing facilities.

4 Hidden Costs of a Hydraulic Leak at Your Plant

Thu, 07 Nov 2019 15:03:00 GMT

Many plants consider a hydraulic leak normal and not a cause for concern. In some cases, small leaks do have something of an inevitability about them. However, even a small leak can cost you far more than you would expect. Here is a look at some of the hidden costs that come with even minor hydraulic leaks and why you need to mitigate them sooner than later.

1. The Cost of Replacing the Leaking Fluid

Replacing fluid in hydraulic systems is a normal procedure and part of any overall hydraulic system maintenance budget. Still, even a small hydraulic leak will add to this cost. Over time, you may find you're paying far too much to replace the fluid.

Consider that a small leak can still represent a loss of several gallons of fluid every month. That loss can turn into an unnecessary expenditure of a few thousand dollars every year. If you're dealing with multiple leaks, that expenditure can climb dramatically.

2. The Cost of Cleaning Up

Cleaning up after a leak eats away at the time you or others could spend doing something else productive. That labor comes at a cost, not just for the time someone uses in the process, but also for the items required to do the actual cleaning.

In some cases, the cleaning products and labor can cost far more than the cost of the fluid itself. This means cleaning up leaks can literally cost more than it's worth. Still, if you want to avoid some other issues, such as accidents, then cleaning up these leaks are a cost you will have to bear.

Disposing of the waste fluid can also come at a cost, especially if your plant operates under heavy waste disposal regulations. Proper disposal can cost a lot, and improper disposal can lead to fines.

3. The Cost of Dealing With Accidents

Hydraulic leaks are a safety hazard. Any area of your facility that has a hydraulic leak is an area that also has a high slip and fall risk. Those slip and falls can cost you a lot, especially if they happen frequently.

Your workers' compensation insurance costs can rise, you may have to deal with lawsuits, and the accident itself can lead to a full stop of operations for a time. All these costs can add up and, in the case of a lawsuit, those costs can ruin a business.

You can also have a fire risk on your hands as well if you're leaking highly flammable fluid. If your operations have a lot of hot surfaces or several ignition sources, then a fluid leak can become a fire waiting to happen. Any accident can lead to costly cleanup, repair, or a temporary stop to production.

4. The Cost of Lowered Equipment Efficiency

It may not always seem like it, but a fluid leak can cause your hydraulic system to work harder to compensate. When your equipment works harder, the potential for increased wear, increased energy costs, and decreased efficiency can affect your bottom line in numerous ways.

A small leak can lead to all these issues, and the leak itself can become worse if you don't deal with it sooner rather than later. When dealing with multiple leaks, the situation only becomes worse, and the costs only grow.

You may only look at the surface costs associated with a hydraulic leak, but the hidden costs can compound astronomically. If you have a leak, deal with it immediately. If you have frequent or multiple leaks, you may need upgrades or repairs to your hydraulic system.

In some cases, hydraulic leaks can occur because your hydraulic system isn't adequate to the needs of your plant. If you're overtaxing the system or constantly repairing it, you may need a custom hydraulic system solution . Contact Quad Fluid Dynamics, Inc., for your hydraulic system needs.

Buying a Used CNC Machine? 6 Things You Should Think About

Thu, 03 Oct 2019 22:22:32 GMT

As you grow your business, you need to have the right tools to keep it growing. In manufacturing, having the right tools may mean having a CNC milling machine. If you don't have a CNC machine already, buying one may feel like a big investment you can't afford right now. Buying a used machine will make your budget happier. Before you buy a used machine, you need to look for certain things.

1. Machine Hours

The more hours that the machine has logged, the more work it has done. Those hours can be hard on the machine and all its components. You need to know how many hours it has logged, as well as how many of those hours were used on various kinds of materials. Some materials are harder to work than others and will have caused more wear and tear on the machine.

2. Service Records

You also need copies of all service records for the machine. You need to see how often it has been serviced as well as how often various parts have been replaced. The records should also tell you what kind of parts were put into the machine, such as OEM parts or aftermarket parts. Each type of CNC machine has standards as to how often it needs servicing, and the records should reflect them.

3. Self-Inspection

Watching the machine work will let you see how well it works, if it sticks anywhere, and if the machine performs the jobs it should. While you watch it work, you should also listen to the machine. You don't want to hear anything that sounds like it grinds or rubs because that indicates the machine may have a problem.

4. Resale Values

You want to make sure that you get the best value for your dollar. You also want to make sure that you don't pay more than you need to. Checking into the original sales price of the make and model machine that you are interested in as well as the average resale price can give you a good idea as to how much to pay for the machine you want.

5. Types of Jobs

Before you buy, you need to know what kinds of jobs you plan to use the machine for. Since it is an investment, you will likely want it to make money for you. Think about how the machine can fit into your current jobs and what kinds of work the machine can take over. If you only buy it for one or two things and don't use it for the rest of the time, it may be a waste of your money.

6. Inspections

As you narrow down your choices to the machines you are most interested in, you should have a service company inspect the unit for you. They will check on the wear on the machine to see if what the service records say agree with what the machine itself says. The service tech can also go more in-depth about the machine than what the service records say. That will give you the best info.

When you buy a used CNC machine, we at Quad Fluid Dynamics, Inc. , can help you. We can look over the machine to see that it is in good working order. We can also set up a maintenance plan for the machine once it is in your facility so that your investment will keep running.

3 Main Reasons Why Your Hydraulic Cylinder Seals Fail Prematurely

Wed, 28 Aug 2019 19:27:03 GMT

Your hydraulic cylinder seals don't cost much. However, these cheap pieces of rubber or plastic hold an incredible amount of importance in any hydraulic system. Typically, hydraulic seals have a good amount of durability, but they can also prematurely fail for several reasons.

Here are some of the reasons why hydraulic seals fail and what you can do to help prevent them from doing so.

1. Your Seals Aren't Installed Properly

Proper and professional hydraulic seal installation is a key factor in preventing premature seal failure. When you or a technician place a seal anywhere on the hydraulic cylinder, you must adhere to several procedures to ensure the installation is a successful one.

To start with, you must choose the right type of hydraulic seals for your system. The wrong type of seal can't handle the pressures of the system and will fail quickly. In a worst-case scenario, the wrong type of seal won't work at all and you'll have an immediate hydraulic leak on your hands.

Other issues can occur during the installation of the seal, such as contamination and damage from mishandling. Seals need proper lubrication during installation, and they need proper orientation. You may not notice it when you look at some types of hydraulic seals but it's possible to install them upside down, which can lead to early failure as well.

Hydraulic seals can also wear quickly and fail faster if they're not installed just right. For example, over-tightening of seals can cause just as many problems as not tightening the seal enough.

2. Your Seals Are Taking On a Lot of Contamination

When contamination infiltrates a hydraulic system, that contamination will start to infect the hydraulic cylinder seals as well. In some cases, certain types of debris will congregate around the seal. The more contamination that builds up around the seal, the less efficient and accurate the seal will be.

Since contamination comes from outside the system, the best way to keep it away from your seals is by keeping it out of your hydraulic system in general. You can usually tell if contamination is the culprit for premature seal failure. If you find tiny pieces of debris embedded in the seal, you'll know contamination was at work.

To prevent contamination from harming seals specifically, you should:

Routinely cycle fluids in the system
Keep the piston area free of buildup
Make sure to filter the oil
Install rod wipers

You may not eliminate all contamination from the system, but the more contamination you keep out, the longer all your hydraulic components will last; this includes your seals.

3. Your Seals Can't Take the Heat or the Fluids

Heat erosion of hydraulic seals occurs when the seals simply can't take the heat and friction buildup of your hydraulic system. Seals can melt, become brittle, and break. Dealing with heat erosion and degradation requires an understanding of your system's operating parameters. Your seals may not have the tolerance for your system.

In such a case, you can upgrade to seals made of materials with more heat resistance. You can also try to increase the amount of lubrication you use in the system.

Erosion and degradation of seals can also occur if your hydraulic system makes use of chemicals the seal can't handle. Chemical damage to hydraulic seals can take on many forms.

Depending on the interaction sparked by the chemicals and the seal's material, you can find your seals softening, shrinking, swelling, or changing color. The best solution for chemical degradation is to replace your seals with seals made of materials more suitable to your system's applications.

Copy of 5 Things to Do to Keep Your Hydraulic System Working Properly #1

Tue, 30 Jul 2019 21:42:34 GMT

Optimum CNC machining is important for keeping components in the best possible shape over time. Poor machining design causes CNC components to wear out prematurely.

By avoiding design mistakes, you can delay repair needs at your industrial or manufacturing facility as long as possible. The following are eight design flaws to avoid for optimum CNC machining.

1. Excessively Small Features

Small features in your CNC design like micro-holes that are under a couple of millimeters in diameter create problems because they make it more difficult for equipment to execute accurate machining. Small features also add to machining time.

You, therefore, should avoid small features in all CNC machining designs at your facility except where they're absolutely necessary.

2. Deep Cavities

Another CNC machining design characteristic that creates problems is deep cavities. Deep cavities in the workpiece are likely to increase the occurrence of tool breakage. Broken tools increase the cost of production due to the resulting repair and replacement expenses.

When it comes to milling cavities, the depth should not exceed a few times the diameter of the tool for optimum design.

3. Tight Part Tolerances

Tighter part tolerances increase the costs of CNC machining operations for several reasons. First off, they require the need for special measurement tools. At the same time, they increase fixturing needs and the amount of scrap that CNC machining work produces.

The function, form, and fit of individual parts all need to result in an acceptable dimension range that is not excessively narrow. Ideally, you shouldn’t specify tolerances if possible if you want to keep machining labor costs down and speed up the machining process.

4. Improper Material for the Application

One of the most important considerations to take into account when optimizing machining design is which material is used for the workpiece.

You should consider numerous factors in choosing your material, including chemical resistance, thermal stability, rigidity, and heat responsiveness needs. A last consideration that is especially important is the material thickness you need.

5. Excessively Thin Walls

CNC machining operations generally proceed with difficulty if the walls of the workpiece are particularly thin. Thin walls complicate the process because they require multiple passes and low cut depths that will take more time and be more cumbersome.

Another issue with thin walls is that they are likely to vibrate excessively, and vibration tends to decrease the accuracy of the machining process.

6. Long Thread Lengths

As thread lengths get longer, the connection they provide does not get any stronger. In fact, once threads exceed a certain length they will no longer strengthen the connection at all.

Keep thread lengths shorter whenever possible to optimize the fastening mechanism of your CNC machining design.

7. Embossed Text

You might need to add text to your machined parts. If you do, you should incorporate engraved text into your design rather than embossed text.

Engraved text is preferable from a design standpoint because embossed text requires more material to be removed from the workpiece. The engraved text will be able to put into machined parts more efficiently than embossed text can.

8. Drilled Holes

Holes that need to be put into machined parts should be interpolated using an end mill. Drilling holes is less efficient because a drill provides less flexibility regarding hole sizes.

Also, using an end mill rather than a drill offers the advantages of improved surface finishes and the ability to multitask with the end mill to machine both slots and pockets in addition to creating holes.

5 Things to Do to Keep Your Hydraulic System Working Properly

Tue, 02 Jul 2019 20:59:59 GMT

Hydraulic systems are in many industries, doing many different jobs. From pressing parts to lifting heavy loads, hydraulic systems save time, make jobs safer, and allow faster completion of work. In order for the hydraulic system to continue this, maintenance of the system is critical. Discover what you need to keep an eye on and check every time you run the equipment.

1. Check the Fluid Level

Every time you use the equipment, check the hydraulic fluid in the reservoir or tank. The system needs to have the proper amount of fluid in it, or the hydraulics will not build the full pressure that they need to do the job you need them to do.

If the oil is low in the tank, you may start to draw air into the system, causing the pump to cavitate and the pressure in the system to drop very quickly. If you add oil to the tank, make sure you use the same oil that is already in the system to ensure you use the viscosity and grade of oil.

2. Check the Filter Indicators

Most hydraulic systems use filters with indicator windows on them to give you a visual indicator to let you know that you need to change the filter. Check the filter indicators before you run the equipment because dirty filters can contaminate the entire system and cause damage to hydraulic cylinders, the pump, and servos in the system.

3. Check the Hydraulic Lines and Fittings

Take a minute to visually inspect the hydraulic lines and fittings in the system. Look for leaks in the lines, fittings that are leaking, or cracks in the hoses. If you see any of these, make repairs before operating the machine.

Leaks in the system may not show up while the system does not run. Start the equipment and do your inspection while pressure is in the lines and the fluid in the system is warm. This is the time you will most likely see a leak or drip in the system.

4. Check the Tank for Aeration

The simplest way to check for air in your system is to check the hydraulic oil tank for air bubbles in the oil. The oil should not be frothy on the surface when the system runs. Use a flashlight to look in through the fill hole of the oil tank. If you see air bubbles on the surface of the oil, you may have an air leak somewhere in the system.

Other causes of aeration can be bad seals on the cylinders, cold hydraulic oil, or oil that is too viscous for the system. If you get air in the system, listen to the hydraulic pump. Often, it will make a noise because it is cavitating and unable to pressurize the system properly.

5. Check the System Temperature

Use an infrared thermometer and check the temperature of the pump, the servos, and the lines regularly as well. High temperatures in the system can damage the parts and require premature replacement of the parts. Most hydraulic systems should run below 180 degrees Fahrenheit when the system is at full temperature.

A Look at External and Internal Gear Hydraulic Pumps

Mon, 03 Jun 2019 18:15:27 GMT

Hydraulic pumps, including gear pumps, come in many different designs. Gear pumps are among the most economical because they are inexpensive, easy to maintain, and efficient. Gear pumps come in two different types, internal and external, and each provides benefits and disadvantages that you should fully understand before installation.

Design of External Gear Pumps

External gear pumps utilize a straightforward design to provide maximum pumping power in a small package. These pumps use moving gear pressure to create a hydraulic flow that will quickly move fluid through your facility. Most external gear pumps handle loads below about 3,000 PSI, which should be more than enough for most types of fluid-processing facilities.

With these pumps, you can find single- or double-pump configurations with spur, helical, and herringbone gears. The latter two types are probably the most popular because they run smoothly and minimize the sometimes-excessive sound volume of these pumps. However, spur pumps typically work best with higher-volume or viscosity fluids.

Advantages and Disadvantages of External Pumps

External gear pumps utilize two similar gears driven by a motor to produce a hydraulic pump action. With the gears on the outside of the pump, the internal chamber will have more room for fluid. As a result, you can move a variety of liquids such as fuel oils, lube oils, polymers, acids, and other industrial chemicals without much difficulty.

Even better, the lack of internal moving parts lets this pump move fluids at high speeds and under high pressure. And the operation volume is relatively low, which decreases the noise pollution.

However, the end clearances — i.e., the size of the fluid output — is fixed and is not adjustable. Finally, solids can cause issues with the pump and may even cause a breakdown.

Design of Internal Gear Pumps

Internal gear pumps differ from external gear pumps because they move the gears inside of the box. They operate on the same hydraulic principles that drive external pumps, though, so you should not struggle to integrate them into your facility. The viscosity range of this pump varies from 1cP to over 1,000,000cP. This diversity provides you with many operational options.

Just as importantly, this pump can handle fluids with temperatures of up to 750 degrees Fahrenheit or 400 degrees Celsius. As a result, you can handle a multitude of high-viscosity liquids for extended periods. And each pump utilizes a bi-rotational design, which means you can reverse the direction of the gears and the direction of your fluid flow.

Advantages and Disadvantages of Internal Pumps

Internal gear pumps utilize a variety of hydraulic principles — including a gear-within-a-gear concept — to move thick fluids throughout your facility. Only two moving parts exist on this pump, which is one of its significant advantages. Pumps with fewer moving parts experience a lower rate of failure because the pump has fewer elements that can malfunction.

Typically, these types of pumps work well with high-viscosity fluids because the gears can move the fluids without difficulty. And each pump works well in both pump directions, ensuring that you move fluid in and out with minimal hassle.

Unfortunately, the pressure threshold is lower than other hydraulic pumps, which could be an issue for high-volume facilities.
