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.
