How To Know When To Change Your Hydraulic Filters

Hydraulic filters are an essential component of hydraulic systems. They help to maintain the cleanliness of hydraulic oil, which in turn ensures that the system operates efficiently and prevents premature wear and tear. However, filters themselves will eventually become contaminated and clogged, necessitating replacement. In this blog, we will discuss how to know when to change your hydraulic filters.

 

First, it is important to understand the role of hydraulic filters in the system. Hydraulic filters are designed to remove contaminants from the hydraulic oil, such as dirt, metal particles, and other debris that can accumulate over time. As hydraulic oil circulates through the system, it passes through the filter, which traps the contaminants before they can cause damage to the system.

 

Over time, however, the filter will become clogged with contaminants, reducing its effectiveness and increasing the risk of damage to the hydraulic system. When this happens, it is important to replace the filter to restore proper function.

 

So, how do you know when to change your hydraulic filters? Here are some signs to look for:

 

Decreased System Performance

One of the first signs that your hydraulic filters need to be changed is a decrease in system performance. This can manifest in a number of ways, such as slower operation of hydraulic cylinders or decreased power output. If you notice a decrease in the performance of your hydraulic system, it is important to investigate the cause, and a clogged filter may be the culprit.

 

Increased Noise

Another sign that your hydraulic filters may need to be changed is an increase in system noise. If you notice that your hydraulic system is making more noise than usual, it could be a sign that the filter is clogged and restricting the flow of hydraulic oil. This can cause increased friction and wear on the system, leading to premature failure if left unchecked.

 

Dirty Oil

A third sign that your hydraulic filters need to be changed is dirty oil. If you notice that the hydraulic oil is visibly dirty or has a burnt smell, it is likely that the filter is no longer effectively removing contaminants from the oil. This can lead to increased wear on the system and decreased performance, and it is important to change the filter and replace the oil to prevent further damage.

 

Increased Operating Temperature

If you notice that the operating temperature of your hydraulic system is increasing, it could be a sign that the filter is clogged and restricting the flow of hydraulic oil. This can cause increased friction and wear on the system, and if left unchecked, can lead to premature failure. It is important to investigate the cause of the increased operating temperature and replace the filter if necessary.

 

 

In conclusion, hydraulic filters are an essential component of hydraulic systems, and it is important to know when to change them to maintain proper system function and prevent damage. Signs that your hydraulic filters may need to be changed include decreased system performance, increased noise, dirty oil, increased operating temperature. By monitoring these factors and performing regular maintenance, you can ensure that your hydraulic system operates efficiently and reliably for years to come.
