What's the function of the oil filter?
The strainer is mounted in front of the oil pump and is usually made of metal screen type. The oil filter is mounted behind the oil pump and connected with the main oil circuit. There are several kinds of metal scraping blades, sawdust filter core and microporous filter paper. Now, the filter paper is mainly made of microporous filter paper.
The function of the oil filter is to filter out the sundries, gums and moisture in the oil, and transport clean oil to the lubrication parts. Because the oil itself of high viscosity, high impurity content in the oil, in order to improve the filtering efficiency, oil filter generally has three stages, respectively, oil strainer, crude oil filter and oil filte
If the oil is not filtered, directly into the lubricating oil, the oil will contain debrisintothe friction pairs, accelerated wear parts, reduce the service life of the engine.
The oil itself contains a certain amount of gum, impurities, moisture and additives. At the same time, in the process of engine operation, the metal debris into, the air debris access, oil oxide production, making the oil in the debris gradually increased.
The friction resistance between the relative moving parts in the engine is reduced, and the wear of the parts is reduced. The lubricating oil is continuously conveyed to the friction surfaces of the moving parts, so as to form a lubricating oil film for lubrication.
