What Does a Hydraulic Filter Do

Hydraulic oil is the most important part of every hydraulic system. In a hydraulic system, no system can work without the proper volume of hydraulic oil. Also, any change in fluid level, fluid properties, etc. can damage the entire system we are using. If hydraulic oil is so important, what happens if it gets contaminated?

The risk of hydraulic oil contamination increases with the use of hydraulic systems. Leaks, rust, gas inflation, cavitation, damaged seals, etc... contaminate the hydraulic oil. Problems created by this contaminated hydraulic fluid are classified as degrading, transient and catastrophic failures. Degradation is a classification of failures that affect the proper functioning of a hydraulic system by slowing down operation. Transients are intermittent failures that occur at irregular intervals. Finally, catastrophic failure is the complete end of hydraulic systems. Contaminated hydraulic fluid problems can become serious. So how do we protect hydraulic systems from contamination?

Hydraulic oil filtration is the only solution for removing contaminants from the fluid in use. Particle filtration using different types of filters will remove contaminant particles such as metals, fibers, silica, elastomers and rust from hydraulic fluids.

 

What is a hydraulic filter?

Hydraulic filters are components of the hydraulic system used to continuously remove contaminants from hydraulic oil. This process will purify the hydraulic fluid and protect the system from damage caused by particulate content. Choose the type of hydraulic filter for a specific application based on its fluid compatibility, application type pressure drop, working pressure, size, design, etc…

Every hydraulic system contains some basic hydraulic filter components such as filter head, bowl, filter element and bypass valve. Filter heads can have inlet/outlet connections of different sizes. It allows contaminated fluid to enter and filtered fluid to exit. The filter bowl is located in a housing that is threaded to the filter head and will protect the filter element by controlling fluid flow. This element is considered the most important component that holds the filter media to remove contaminants. The bypass valve may be a relief valve that opens to allow direct hydraulic fluid flow if the filter contains more dirt deposits.

Hydraulic filters are located in different parts of the hydraulic system and prevent contaminant particles from entering the system. Air filters, suction filters, pressure filters, return filters, and off-line filters are some common hydraulic filters.

The air filter is a hydraulically applied breathing system in operation, drawing air in and out.
The oil suction filter/hydraulic pump filter is used as a hydraulic oil purification component installed before the hydraulic pump.
A pressure filter is placed after the hydraulic pump to handle system pressure and flow.
The oil return filter purifies the hydraulic oil before returning to the tank.
Offline/renal circulation/recirculation filters are small self-contained subsystems consisting of filters, pumps, motors and hardware connections.
With the exception of off-line filters, hydraulic filters work on a similar basic principle. In general, the working fluid in the hydraulic system enters from the inlet of the hydraulic filter, and is pumped out from the outlet of the hydraulic system after filtering. Due to continuous operation, the deposits of dirt particles at the inlet of the filter element will create a pressure differential between the inlet and outlet of the filter. When the bypass relief valve senses this pressure differential, the valve will open and pass fluid directly from the inlet to the outlet by sending instructions to change/clean the filter.

Why use a hydraulic filter?

Hydraulic filters are mainly used in various hydraulic systems in industry. These filters have many advantages to ensure the safe operation of hydraulic systems. Some of the benefits of hydraulic oil filters are listed below.

Eliminate the presence of foreign bodies in hydraulic oil
Protects hydraulic systems from particulate contamination
Improve overall efficiency and productivity
Compatible with most hydraulic systems
low maintenance cost
Increase the service life of the hydraulic system
