What is a hydraulic filter?

After the impurities are mixed into the hydraulic oil, it will seriously affect the normal operation of the hydraulic filter and cause the oil to deteriorate. According to production statistics, more than 75% of the failures in the hydraulic filter are caused by impurities mixed in the hydraulic oil. Therefore, maintaining the cleanliness of the oil and preventing the pollution of the oil are very important to the hydraulic system.

There are many ways to collect pollutants in fluids, and the device made of filter material to capture pollutants is called hydraulic filter. Magnetic filters that use magnetic materials to adsorb magnetic pollutants are called magnetic filters. In addition, there are electrostatic filters, separation filters and so on.

The hydraulic filter can filter the mechanical impurities remaining in the hydraulic system after cleaning, the impurities entering the hydraulic system from the outside; the impurities generated during the working process, the fragments formed by the hydraulic action of the seal, the metal powder caused by the relative wear of the movement, the oil Glue, etc. due to oxidative deterioration.

Technical requirements for hydraulic filters: (1) The filter material should have a certain mechanical strength. (2) Under a certain working temperature, the performance should be kept stable. (3) It has good anti-corrosion ability. (4) The structure is as simple as possible and the size is compact. (5) Easy to clean and maintain, easy to replace the filter element.
