Summary of specific functions of hydraulic filter

The hydraulic filter is used to filter various impurities in the hydraulic system. The main source is the mechanical impurities left in the hydraulic system after cleaning. The external impurities enter the hydraulic system through the fuel filler, and the dust enters the hydraulic system. During the working process, the debris formed by the sealing hydraulic action, the metal powder produced by relative wear and movement, etc.

There are many ways to collect pollutants in liquid, and the device made of filter material to collect pollutants is called filter. Magnetic filters that absorb magnetic contaminants with magnetic materials are called magnetic filters. In addition, there are electrostatic filters, independent filters, etc. In the hydraulic system, the collection of contaminated particles in the liquid is called the hydraulic filter. In addition to the use of porous materials or winding slit to intercept pollutants, the widely used hydraulic filter is the magnetic filter and electrostatic filter used in the hydraulic system.

When the above impurities are mixed into the hydraulic oil, with the circulation of the hydraulic oil, the damage of the hydraulic system will be everywhere, seriously affecting the normal operation of the hydraulic system, such as a small gap and section between the relative moving parts in the hydraulic system. Small holes and gaps are stuck or blocked; oil film between moving parts is damaged, gap surface is scratched, internal leakage is increased, efficiency is reduced, heat is increased, chemical effect of oil is intensified, and oil deteriorates.

According to relevant statistics, more than 75% of the faults in the hydraulic system are caused by the mixing of impurities in the hydraulic oil. Therefore, it is very important for the hydraulic system to keep the oil clean and prevent the oil pollution
