Hydraulic filter

There are many ways to collect pollutants in fluids. Devices made of filter materials to capture pollutants are called filters. 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. In the hydraulic system, any collection of pollutant particles in the fluid is collectively referred to as a hydraulic filter. The most widely used hydraulic filters are magnetic filters and electrostatic filters used in hydraulic systems, in addition to the use of porous materials or wound fine slits to intercept pollutants.

After the above impurities are mixed into the hydraulic oil, with the circulation of the hydraulic oil, it will play a destructive role everywhere, seriously affecting the normal operation of the hydraulic system, such as making small gaps (measured in μm) and joints between the relatively moving parts in the hydraulic components. The flow holes and gaps are stuck or blocked; the oil film between the relatively moving parts is destroyed, the surface of the gap is scratched, the internal leakage is increased, the efficiency is reduced, the heat is increased, the chemical action of the oil is aggravated, and the oil is deteriorated. According to production statistics, more than 75% of the failures in the hydraulic system are caused by impurities mixed in the hydraulic oil. Therefore, it is very important for the hydraulic system to maintain the cleanliness of the oil and prevent the pollution of the oil.

General hydraulic filter is mainly composed of filter element (or filter screen) and shell (or skeleton). The flow area of the oil is composed of numerous tiny gaps or pores on the filter element. Therefore, when the size of impurities mixed into the oil is larger than these tiny gaps or pores, they are blocked and filtered out of the oil. Since different hydraulic systems have different requirements, it is impossible to completely filter the impurities mixed into the oil, and sometimes it is not necessary.
