The main function of the oil filter is to filter most impurities in the oil, keep the oil clean and extend its normal service life. In addition, the oil filter should also have strong filtering capacity, small flow resistance and long service life.
The role of oil filter Generally, all parts and components in the engine are lubricated by oil to achieve normal operation, but the metal debris, dust entering, carbon deposits oxidized at high temperature and some water vapor generated during the operation of parts and components will be continuously mixed into the engine oil, which will reduce the normal service life of the engine oil for a long time, and may affect the normal operation of the engine in serious cases.
Therefore, the role of the oil filter is reflected at this time. In short, the main function of the oil filter is to filter most impurities in the oil, keep the oil clean and extend its normal service life. In addition, the oil filter should also have strong filtering capacity, small flow resistance and long service life.
The oil filter is mainly composed of filter paper and housing, as well as sealing ring, support spring, bypass valve and other auxiliary components. These auxiliary components also play a very important role. For example, the role of bypass valve is that when the filter paper fails due to excessive impurities, the oil will flow into the engine through the bypass valve for lubrication. However, only the oil filter can be seen from the appearance, and the filter paper, bypass valve and other parts can not be seen.
