The function of hydraulic oil filter

The main function of the hydraulic oil filter is to filter the hydraulic oil. Various impurities inevitably appear in the hydraulic system. The main sources are: mechanical impurities still remaining in the hydraulic system after cleaning, such as scale, casting sand, welding slag, iron filings, paint, paint skin and cotton yarn scraps, etc. Impurities entering the hydraulic system, such as dust entering through oil fillers and dust rings, etc.Impurities generated during the working process, such as the debris formed by the hydraulic action of the seal, the metal powder generated by the relative wear and tear of the operation, and the oil due to oxidation and deterioration,colloids, asphaltenes, carbon residues, etc. 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. It will get stuck or blocked that the small gaps between the relatively moving parts in the hydraulic components and throttling holes and gaps. destroys the oil film between the relatively moving parts, scratches the surface of the gap, increases the internal leakage, reduces the efficiency, increases the heat generation, aggravates the chemical action of the oil, and deteriorates the oil. 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.
