Recognizing Common Needs For Hydraulic Hose Repair

Posted on: 15 December 2022

Hydraulic systems must maintain a precise pressure level with the fluid in the system in order for the machine to function as it's intended. Unfortunately, this can sometimes lead to malfunctions, leaks, and hydraulic hose failures. Understanding some of the most common reasons for problems with your hydraulic system can make troubleshooting and repair easier to handle. Here's a look at some of the things that you should know and watch for.

Thermal Damage

If you choose a hose that's not designed for the level of heat output in your hydraulic system, the hose will suffer thermal damage. This can harden the hose material or cause it to become brittle. Damage like this increases the risk of cracks, weakens the integrity of the hose, and makes it more likely that you'll have a leak and need to replace hose sections. Make sure that any hydraulic hose you select is properly rated for the thermal range that the hose is exposed to in your environment.

Air In The Hydraulic Fluid

Many forms of hydraulic hose are woven fibers, which makes them vulnerable to deterioration and pinhole damage. This can allow air to seep through, creating aeration in the hydraulic fluid. Those air bubbles disrupt the viscosity of the hydraulic fluid, which alters the heat distribution. In some applications, this leads to thermal issues, excessive pressure, or fluid flow disruptions, especially if you end up with larger air pockets. You'll have to replace any pinhole-damaged hoses and potentially bleed the lines to remove any air.

Incorrect Hose Selection

If you choose the wrong hoses for your application, whether it's a hose that maintains insufficient pressure, can't withstand the hydraulic fluid temperature, or one that's stretched too far, you can face failure in your hydraulic system. Make sure that you choose the right hoses that fit properly so that you get consistent, reliable hydraulic pressure flow. 

Improper Connectors

When the threaded connectors are incorrect or missing a necessary gasket structure for sealant, you'll experience pressure inconsistencies and leaks in your hydraulic system. Make sure you take time to consider your hydraulic system structure, including the connections for each hose, so that everything seals together properly to maintain the pressure in the system.

These are just a few of the many things to know when it comes to hydraulic system malfunctions and necessary repairs. The more proactive you are about taking care of your hydraulic system, the less risk you'll face of repairs and similar issues.
