What are hydraulic filters?
Hydraulic filters are used in hydraulic systems and machines to purify liquids and oils from contamination and protect the system against various particle contents. Approximately one million particles larger than 1 micron enter your hydraulic system every minute. These pollutants usually come from the following:
🔰 Ingestion through the tanks of system components
🔰 Internal production of particles from hydraulic system components
These particles can severely damage your system components and as a result cause you problems and lead to device failure. Maintaining a good hydraulic filtration system will help you extend the life, reliability and performance of your equipment and avoid unnecessary worry and expense.
Types of hydraulic filters based on their structure
There are different types of hydraulic filters. The three most common types are bag, net and magnetic filters. Pollutants cannot pass through them because they are solid. We usually use bag filters to filter particles such as dust and rust. They are joined together to create a metal fabric. They can be made to exact sizes, allowing engineers to choose the right size based on the contaminants. They use a magnetic charge that is used to filter out magnetic pollutants.
What are the criteria for choosing a hydraulic filter?
The type of hydraulic filter used depends on the level and position of the filter. It is also selected based on fluid compatibility, type of application, working pressure, size, design and more. Flow compatibility describes how much fluid flow is allowed through the filter. Pressure describes the maximum operating pressures that a filter can withstand.
Types of hydraulic filters based on their alignment
Circulation based on their position and level in the system is as follows:
Suction filters: These filters are located just before the pump and from the pump in front of large polluting particles. and protect the harmful substances in the fluid. This filter uses a wire screen to filter particles. High pressure hydraulic filter: This filter between the pump and sensitive system components such as control valves and actuators. ) is located. The filters used in the system remove a large amount of small pollutants.
Return flow filters: These filters are located at the end of the return flow line, between the fluid tank and the control valve. They filter the fluid before it enters the tank and remove common contaminants produced by the system components.
Offline Filters: These filters are part of the main loop of the hydraulic filter system. are not They clean the hydraulic fluid before it enters the system.
In-Tank Breathing Filters: Many contaminants can enter the hydraulic system through air. Therefore, these filters are placed on the tank to prevent moisture and air particles from entering it.
