The main function of the hydraulic oil filter is to filter the oil, and various impurities inevitably appear in the hydraulic system. The main sources are: mechanical impurities remaining in the hydraulic system after cleaning, such as scale, casting sand, welding slag, iron filings, paint, paint and cotton yarn scraps, etc., and impurities that enter the hydraulic system from outside, such as through the fuel filler and Dust that enters the dust-proof ring, the impurities generated during the working process, such as the fragments formed by the hydraulic pressure of the seal, the metal powder generated by the relative abrasion of the movement, the gum, asphaltene, carbon residue, etc. generated by the oil due to oxidative deterioration.
