Functions and advantages of hydraulic filter

The function of hydraulic filter is to filter various impurities in the hydraulic system. Its sources mainly include mechanical impurities remaining in the hydraulic system after cleaning, such as rust, casting sand, welding slag, iron filings, paint, paint skin and cotton yarn filings, and impurities entering the hydraulic system from the outside, such as dust entering through the oil filler and dust ring; Impurities produced in the working process, such as the fragments formed by the hydraulic action of the seal, the metal powder produced by the relative wear of the movement, the colloid, asphaltene, carbon slag produced by the oxidative deterioration of the oil, etc.

Advantages of hydraulic filter
(1) The filter material shall have a certain mechanical strength to ensure that it will not be damaged by the action of hydraulic pressure under a certain working pressure.
(2) Under a certain working temperature, the performance shall be stable; It has enough durability.
(3) It has good corrosion resistance.
(4) The structure shall be as simple as possible and the size shall be compact.
(5) It is easy to clean and maintain and replace the filter element.
(6) Low cost.
