The so-called oil filter generally refers to a filtering device for filtering hydraulic oil. It is generally composed of a housing and a filter element.
According to the material of the filter element, it can be divided into paper filter element oil filter, chemical fiber filter element oil filter, glass fiber filter element oil filter, stainless steel filter element oil filter and so on.
According to the structural form, it can be divided into a net type oil filter, a line gap type oil filter, a folded filter type oil filter, a sintered type oil filter, a magnetic oil filter, and the like.
According to the position where the oil filter is placed, it can also be divided into an oil suction filter, a pipeline oil filter and a return oil filter. Considering the self-priming performance of the pump, the oil suction filter is generally a coarse filter.
Feature
The oil suction filter is generally installed at the oil suction port of the oil pump to protect the oil pump and other hydraulic components to avoid inhalation of contaminated impurities, and can effectively control the cleanliness of the hydraulic system.
The oil return filter is used for oil system oil return filtration, filtering metal particles generated in the hydraulic system due to component wear, and pollutants generated by the heart seal, so that the oil flowing back to the oil tank is kept clean.
The WU type oil suction filter currently used is a coarse filter, which has a simple structure, large oil resistance, small resistance, easy installation, convenient replacement of the cleaning filter or maintenance system, and has a filter pollution transmitter and oil path. Bypass valve to improve the reliability of the hydraulic system. The XU-A oil return filter is a fine filter. Its simple structure and high filtration precision can effectively improve the reliability of the hydraulic system.
