The main function of the hydraulic oil filter is to filter hydraulic oil in hydraulic system, inevitably appear various impurities. The main origins are: after cleaning is still
mechanical impurities in the hydraulic system, such as rust, sand casting, welding slag, iron, paint, paint leather and cotton dust, impurities outside into the hydraulic
system, if the dust into the gas and dust ring at work; impurities produced in the process, such as the seal by the hydraulic effects on the formation of debris, motion relative
wear of the metal powder, oil produced by the oxidation of the glial, asphaltene, carbon residue and other. The contamination of hydraulic oil, hydraulic oil with the cycle of
the destructive, everywhere, seriously affecting the normal operation of hydraulic system, such as the small gap between the relative motion components in hydraulic elements
(to) and throttling hole and slot card dead or blocked; oil film between the relative movement of the parts of the broken scratch the surface, the gap, increase the internal
leakage, reduce efficiency, increase the heat, increased chemical effects of oil, the oil deterioration.
