High quality and efficient glass fiber hydraulic oil filter 0030D010BN4HC engineering machinery engine parts
The role of the filter
The oil of the hydraulic system is inevitably mixed with various impurities. Its sources mainly include: impurities remaining in the hydraulic system at the beginning, such as iron filings, welding slag, casting sand, paint skin and cotton yarn residues left during washing, etc.; impurities entering the hydraulic system from the outside, such as from the oil inlet, Dust entering the dust ring, etc.; impurities mixed in the oil from the air and transportation equipment during transportation; impurities generated during the working process, such as debris formed by the hydraulic action of the sealing material, and metal dust generated by the wear of the moving pair , The acids, colloids, asphaltenes, carbon residues, etc. produced by the chemical action of the oil at high temperatures, and solid impurities formed by the dissolution of sealing materials, rubber hoses, and container inner wall coatings in the oil.
The main function of the filter is to filter various impurities mixed in the oil, control the cleanliness of the oil, reduce the pollution of the oil entering the system, and ensure the normal operation of the system. The requirements of most hydraulic systems for oil are not based on the quantity of impurities in the oil, but on the basis of the maximum particle size (diameter d of impurities) of impurities contained in the oil. The filter can filter out the nominal size of the impurity particle size. The size is called the filtering precision. The hydraulic components are highly sensitive to impurities in the oil and require high filtration precision. Different hydraulic systems have different requirements for the filtration precision of the oil. When the system pressure is different, the filtration precision requirements are also different.
