Tips to Help You Avoid Common Fluid Power Design Mistakes

As a longtime hydraulic company in Minnesota, we’ve gained a lot of experience in fluid power design over the years. This has given us more than enough perspective to tell when manufacturers or other hydraulic companies are making some critical mistakes in their designs.With this in mind, here are some examples of common fluid power design mistakes and how you can avoid them:

  • Mixing up pressure and flow: This is a mistake that is especially common among designers who are new to the hydraulic field. They tend to want to get more force to lift up bigger, heavier loads, and think they need bigger pumps to produce that force. In actuality, a smaller pump often allows them to raise the pressure slightly while still preserving some of the input horsepower. The confusing of pressure and flow is even worse when talking about valves—if you put an inline flow control on a system and turn it down, the upstream pressure will rise. The mistake people make is thinking this is actually them adjusting pressure, which isn’t the case at all.
  • Not having the right reservoir size: Another common mistake made by hydraulic system designers is failing to provide enough reservoir volume. Having the correct reservoir size helps with cooling, aeration removal and contamination settling. If the reservoir hasn’t been properly sized for the cylinder, there could be some catastrophic damage to the system. Therefore, it is crucial to ensure before using any system that the right reservoir size is in place.
  • Not abiding by strength limitations of cylinder columns: This mistake can be made by just about any designer, whether beginning or advanced. The cylinder’s column strength must be obeyed. This strength is determined by the diameter and length of the rod, as well as the mounting configuration of the cylinder and its rod attachment. This entire system is going to have limitations to how much it’s capable of handling, and if you exceed those limitations there is a chance you could be dealing with some buckling or misalignment, which could permanently damage your hydraulic system.
  • Continuing to use old technology: Just because you’re comfortable with your old technology doesn’t necessarily mean it’s the best technology for your uses. Hydraulic system design has come a very long way over the years, so why should you settle for handicapping yourself with outdated technology that isn’t nearly as efficient as what’s available today?
  • Not considering your filtration requirements: You’re going to need a lot more than just a small paper filter assembly to protect your hydraulic system, at least if you have any real desire to avoid some expensive repairs. Paper filters are inefficient, can absorb water and do not have sufficient dirt-holding capacity. You should instead choose synthetic filters, which are more expensive but will perform better and guard you against the need to make unnecessary repairs.

At M & M Hydraulic Co., we’ve been honing our expertise in fluid power design for years. With our experience, we’ve seen firsthand the most common mistakes in hydraulic system design, and we’re here to help you avoid them. Hydraulic systems are intricate and can be easily damaged if not designed correctly. Below are some practical tips to help your fluid power design be efficient and functional without falling into the traps of common errors.

Understanding Pressure and Flow

New designers often confuse pressure and flow. While it seems logical that a larger pump means more power, this isn’t always the case. A smaller pump can actually offer better control of pressure without compromising efficiency. Pressure refers to the force of the hydraulic fluid, and flow refers to the amount of fluid moving through the system. Both must be properly balanced to avoid inefficiency and potential damage.

Choosing the Right Reservoir Size

Hydraulic systems require adequate fluid storage for proper cooling, filtration, and aeration. Failing to choose the correct reservoir size can lead to overheating, contamination, or even complete system failure. It’s crucial to select a reservoir that can handle the demands of the system, making sure there’s enough capacity to accommodate changes in fluid levels during operation.

If the reservoir is too small, you risk damaging the system. A larger-than-necessary reservoir can be wasteful and may contribute to unwanted system complexity. Properly sizing the reservoir keeps everything running smoothly and ensures that the hydraulic fluid stays clean and cool.

Adhering to Cylinder Column Strength Limits

Hydraulic cylinders have specific strength limits, and exceeding these limits can lead to serious issues like misalignment or buckling. The strength of the cylinder depends on the rod’s size, length, and mounting configuration. Always check the specifications to ensure the cylinder can handle the forces your system requires. Ignoring these limits could result in expensive repairs or system failure.

Upgrading Technology for Efficiency

Sticking with old hydraulic technologies might feel familiar, but it can prevent you from achieving the efficiency and performance your system needs. The hydraulic field has advanced significantly in recent years, with improved pumps, valves, and control systems that are far more efficient than older models.

Upgrading to newer technology guarantees that your hydraulic fluid is used in the most effective way possible, reducing energy consumption and improving system reliability. Older systems may be harder to maintain and might not be able to handle the demands of modern applications.

Selecting Proper Filtration for Hydraulic Fluids

The filtration system you choose plays a critical role in protecting your system. Basic paper filters are ineffective at capturing contaminants, leading to pump, valve, and component damage. Instead, use synthetic filters, which are more efficient and durable. These filters remove water and particles from the fluid, making sure the system runs cleanly and efficiently, minimizing wear on components.

Understanding the Basic Components of a Hydraulic System

Basic Components of a Hydraulic System

We get a number of common questions about our products at M&M Hydraulic Company, and some of these surround how specific components work. Hydraulic components are a great example, and as we offer several kinds of hydraulic components like hydraulic hoses and hydraulic tubing for multiple industries, we regularly get questions about how they work.

Hydraulic systems rely upon pressurized fluids for power generation to perform heavy lifting or other rugged tasks, providing precision for repetitive applications. To work efficiently, hydraulic systems are made up of various parts that facilitate fluid transport, heat transfer, pressure control, energy creation, and more. Learn about the individual components of a typical hydraulic system, and how they work together to provide high-performance functionality for a variety of applications – and of course, contact us for further information or to make an order of any of our hydraulic system products!

Common Hydraulic Components Found in Hydraulic Systems

Each part of a hydraulic system is important to the functionality of the whole. If one piece fails, the entire system can lose pressure and fluids, or even produce too much pressure. Situations like these are dangerous when heavy machinery, lifts, or other equipment are involved. Water-, petroleum-, and mineral-based hydraulic fluids, as well as synthetics, are the vehicle for energy transmission through multiple parts of a hydraulic system, as well as thermal transfer and lubrication.

Here are some basics on each of the major hydraulic components you’ll typically find:

Reservoir Oil Tank

Hydraulic oil requires a storage location, and a hydraulic reservoir is just that. The oil tank holds the fluids required for the system, as well as filter contaminants from entering in. It’s one of the most critical components of a hydraulic system since it stores and protects the system’s essential fluid supply. It also helps to cool fluids and allow solids to settle within them, plus to allow air to escape from the area.

Pipes

Hydraulic fluids need to be carried from one point to another without losing significant pressure, and with minimal disruption. That’s why pipes are prominent in hydraulic systems; they are designed for efficiency, strength, and high pressures. Some of the most common materials used include steel or ceramic-lined steel. Pipes help keep dangerous fluids contained while carrying them from one point to another within the system.

Pumps

Hydraulic pumps provide power to move fluid throughout a system under pressure, something that could not be done through simple gravity alone. As such, it is considered the heart of the hydraulic system.

This hydraulic component can also be responsible for controlling the pressure of fluids, ensuring they reach their intended destination effectively. Some common types of pumps used in hydraulic systems include gear pumps, vane pumps, and piston pumps.

A Power Source

Naturally, you will need power to facilitate this entire operation. Electric motors are the most common for use with hydraulic components, helping to generate GPM within the system itself. Other sources of power include gasoline or diesel engines, as well as wind turbines in specialized applications.

Actuator

The role of the actuator is to convert hydraulic energy into mechanical force. This component can take many forms, but essentially, its purpose is to facilitate movement within the system. In most cases, actuators are made up of a cylinder and a piston that moves back and forth as fluid is sent through it.

Valves

Valves are used in hydraulic systems to regulate the flow of fluids and control pressure levels. They play an integral role in directing fluids to specific areas within the system or even changing the direction of flow. Different valve types have different functions, such as relief valves for controlling overpressure and directional valves for controlling the direction of fluid flow.

Filters

As with any system that involves fluids, filters are critical for preventing contaminants from entering and potentially damaging components. They help to keep the fluids clean and functioning at optimal levels, ensuring the system continues to operate smoothly.

How Are Hydraulic Systems and Hydraulic Components Used?

There are a huge range of possible industrial uses for hydraulic systems, including any setting that dictates fast, precise or repetitive movement. Hydraulic components are ideal for heavy lifting, as well. Because of these qualities, they’re ideal for several major industries:

  • Production lines and materials handling: For various automated processes, hydraulic systems can help transport goods or equipment while allowing for quick and precise movements.
  • Presses and crushers: Hydraulic presses are vital for shaping and forming metal, such as in the auto industry.
  • Heavy equipment: Backhoes, earthmovers and other equipment all require hydraulic systems to lift and move heavy loads safely.
  • Processing machinery: Whether for metal, plastic, paper, textiles or other products, hydraulic systems help to power and control all sorts of industrial processing machines.
  • Agricultural machinery: For plowing, harvesting and other agricultural tasks, hydraulic systems help to make work more efficient.

Common Causes of Hydraulic System Failure

Keeping any hydraulic system in your facility in working order is naturally a key priority, and a big part of this involves understanding why and how hydraulic systems can fail. There are a number of possible reasons here, but also some basic hydraulic system failure prevention tactics you can take to avoid them and maintain your system.

At M&M Hydraulic Company, we offer a huge range of services for hydraulic systems around Minnesota and nearby states, including hydraulic cylinder repair, diagnostics, testing, tear down and assembly, machining service for barrels, chrome rods, heads, pistons and more. Here are some of the most common issues that can affect hydraulic systems, plus important hydraulic system failure prevention approach recommendations from our team.

Over-Pressurization

Part of a hydraulic system’s initial build and installation involves defining a specific amount of pressure it’s meant to operate under. This is often related to the size and power of the system, with more powerful systems requiring higher pressures.

If the wrong pressure is used, though, or if the system is not maintained and begins to operate at higher pressure levels over time, it’s possible for over-pressurization to occur. This will cause damage to seals and other components in the system, leading to leaks and potential failure.

Proper maintenance is key here – this includes regular pressure checks and adjustments as necessary. And if you do experience a leak due to over-pressurization, call our team right away for quick service.

Contamination

Another common reason for hydraulic system failures is contamination within the fluid itself. There are several types of contamination that can lead to this kind of issue: Water or air bubbles trapped in the fluid, particles from outside sources entering the system, or improper fluid storage that allows contaminants to mix in.

To prevent contamination, it’s important to properly store and handle hydraulic fluid, plus regularly clean out any filters or screens within the system. Additionally, early detection of contamination is key – keep an eye out for changes in fluid color or consistency, and call our team if you notice anything unusual.

Abrasion

Hoses are a key component within hydraulic systems, but they can also be a source of failure if not properly maintained. Over time, hoses can become worn down or abraded due to constant movement and exposure to high pressure.

To prevent this kind of damage, it’s important to regularly inspect hoses for signs of wear and tear, including cracks, bulges, or leaks. Replace any damaged hoses immediately to avoid potential failure.

Connection Problems

In other cases, hoses may remain intact but fail due to connection issues. This can include loose fittings, improper installation, or damaged seals. These can be quite problematic, causing the fitting to blow off the hose and damage the entire system.

To prevent these types of failures, make sure all connections are secure and properly tightened during installation. Additionally, regularly check connections for signs of wear or damage.

Air Trapped in Fluid

There can also be situations where air is present in the hydraulic fluid, causing problems with system operation. This can lead to a few problems, from air becoming compressed and damaging internal components to the temperature rising too high. You might even see pump damage that will lead to hydraulic system failure with time.

To avoid air trapped in the fluid, properly bleed the system before use and regularly check for signs of air bubbles within the fluid. If you do notice any issues, call our team for assistance.

Vital Role of Regular Maintenance

While we went over specific issues that could lead to hydraulic system failure, it’s important to note the vital role of regular maintenance in preventing these issues. Regular inspections and service not only help detect potential problems early on, but also ensure your system is running at its best and extends its overall lifespan.

Understanding What Type of Chrome You Need

When discussing the processes associated with engineering chrome and chrome plating in Minnesota and the applications for which it will be used, there is a lot of technical terminology that the layperson is likely to be unfamiliar with. If you are in the market for chrome plating for a specific project or application, it’s important for you to at least have a minimal level of understanding about some of these important industry terms, so you’ll be better able to recognize the differences in the various types of processes used to make these products.

With this in mind, here is some important information from our team that specializes in chrome plating in Minnesota.

Engineering chrome

Engineering chrome is a type of chrome that features a thick layer of chrome directly applied on to a different base material. It features a shiny and metallic finish on its exterior. However, this does not mean its primary use is aesthetic—this is just a secondary effect. It also is highly protective, and is commonly used in cylinder rods, piston rings, gun bores and railers.

Decorative chrome

As the name suggests, decorative chrome is generally used more for aesthetic purposes than practical ones. It typically features an underlayment of nickel and copper, with a thinner layer of chromium covering it on top. This layer provides some smoothness, reflectivity and resistance to corrosion, but ultimately does not offer the same level of durability and practical functionality you’d get out of engineering chrome. It’s most likely to be used in parts such as plated wheels or truck bumpers.

Hard chrome plating

This type of chrome plating is most commonly used in applications that require a lot of durability, as they offer some outstanding corrosion protection, have a reduced coefficient friction and are ideal for use in settings that require a post plate machine operation to achieve the specific finish and size sought by the manufacturers.

Thin dense chrome

Dense chrome plating typically comes in the form of electroplated chromium. This material is developed using some specific chemistry in the bath to produce a uniform thickness in the coating while still being able to maintain some very tight tolerances.

Flash chrome plating

This type of chrome plating features an extremely thin layer of chrome, which is ideal for applications that will only be exposed to light wear. It still provides very good corrosion resistance despite its thinner measurement, and has a reduced coefficient friction, tight tolerances and improved release properties.

These are just some examples of the different variations in chrome and chrome plating that you’re likely to come across when investigating your options with your chosen manufacturer. Again, while you don’t need to have thorough industry knowledge to make the proper selection, it’s at least important that you understand the basic differences in these options and the types of benefits and uses that come with them.

Why You Need Safety Release Valves

Are you familiar with the importance of safety release valves? These hydraulic parts in Minnesota are essential for the proper safety and operation of hydraulic systems. In fact, it’s typically best to have more than one safety valve per system.

Why are these hydraulic parts in Minnesota so crucial? Read on to discover how safety valves contribute to the overall functioning of hydraulic systems.

Their Function

The main relief valve on a hydraulic system prevents the system from working above a designated pressure. A backup valve steps in to stop the system if this critical pressure is exceeded without the main valve stopping it. This secondary valve only allows the system to go slightly beyond the working pressure. It will stop the system before it reaches a critical level that could damage components.

Their Purpose

Have you ever experienced a blown connection? If safety release valves aren’t among the included hydraulic parts in Minnesota, the system suffers. A hydraulic system can reach critical pressure, which will cause a connection to fail. When this blows, it can cause damage to the system, create a mess around the system, cause injuries to those nearby and shut down operations. Safety release valves help prevent all of these issues. They keep systems running smoothly and save time, money and hassle.

Their Type

Keep in mind as you select hydraulic parts in Minnesota that not all safety release valves are created equal. These parts come in a variety of shapes, styles and sizes. They may also include multiple settings. Do you need assistance with choosing the best safety release valve for your system? Experts in the hydraulic industry can help you with this selection. Keep in mind that hydraulic symbols are used to indicate the function of components. It’s crucial to understand these symbols to determine which component is the best solution for your system.

Their Maintenance

It’s important to choose the right safety release valve for your hydraulic parts in Minnesota. It must be large enough to handle the flow. It must also be properly maintained so it can stop the system when needed. Secondary safety release valves should be smaller but should also be able to handle the diversion of the pump flow if needed. Keep in mind that this secondary valve is often your last line of defense against disaster.

To properly maintain your safety valves, inspect and clean your system regularly. If any small issues arise, take care of these right away. This includes the repair or replacement of hydraulic parts in Minnesota. Consult with experts in this industry to properly care for your safety valves.

Partner with the Pros

Don’t take any chances with your hydraulic system. Use the right safety release valves and achieve safe and efficient operation. To do so, partner with experts in the industry who can help you select the best hydraulic parts in Minnesota.

Hydraulic Troubleshooting: What You Need to Know

Do you know what to do if you suspect you need hydraulic repair in Minnesota? Where should you start? What troubleshooting should you do to determine the problem? If you need a bit of guidance, the following tips are for you.

These are the basics you need to know as you get started with hydraulic repair in Minnesota. If you have any additional questions, don’t hesitate to call for backup from a trusted hydraulic repair service in Minnesota.

Basic Functions

First, you must understand the basic function of the various hydraulic components. Troubleshooting will be impossible if you don’t know these functions or how to identify each component. Valves may look similar but perform entirely different functions. Pumps may be in good condition but misdiagnosed due to common issues. To be able to successfully troubleshoot hydraulic repair in Minnesota, first learn all the parts to the system and what they do.

Troubleshooting Procedures

Once you know how the system operates and how each part contributes to the process, you can begin to troubleshoot for hydraulic repairs in Minnesota. You should start by becoming familiar with two common troubleshooting procedures.

First, learn how to determine if a pump needs hydraulic repair in Minnesota. To test a pump, check the oil flow from the case drain line. To do so, direct the flow of the hose into a container and time the flow for 60 seconds. If there is a flow rate of one to three percent of the maximum volume, the pump is okay.

The second common test is to check the accumulator. To test the operation of this component, you can use one of three methods. For the first process, turn off the pump and allow the pressure to reduce to zero. Then, install a charging rig with a gauge on the Schrader valve. Read the gauge to determine the nitrogen pre-charge. For the second method, after turning off the pump, watch the pressure gauge. This should gradually drop, then speed up as it approaches zero. Where the needle starts to rapidly drop is the pre-charge pressure. The third method involves using an infrared camera or a temperature gun. Use one of these tools to check the sides of the accumulator shell. If the pre-charge is correct, the lower half of the shell should be warmer than the upper.

System Adjustments

Troubleshooting and hydraulic repair in Minnesota further requires a knowledge of how to properly adjust the system. Random valve adjustments and control cranking will result in more damage than good. You must be trained in the precise setting of pressure reducing valves, pump compensators, relief valves and pre-charging accumulators. With this knowledge, you will be able to make the right adjustments for hydraulic repair.

Hydraulic Symbols

You should never attempt hydraulic repair in Minnesota without first gaining an understanding of hydraulic symbols. One small symbol can tell a trained technician five or more things about the component. Often, one small letter or number difference can make a huge difference in what the component does and how it will affect the entire system. You can’t simply base troubleshooting and repairs on what the part looks like. You must be able to read the symbols to have a more in-depth understanding of the part.
