When the machine is running, it needs some lubricating oil to lubricate to reduce the frictional resistance between the relatively moving parts in the engine and reduce the wear of the parts. When the machine is running, the oil is continuously transported to the friction surfaces of various moving parts to form a lubricant film for lubrication. The engine oil itself contains a certain amount of gum, impurities, moisture and additives. At the same time, during the operation of the engine, the introduction of metal abrasive debris, the entry of debris in the air, and the generation of oil oxides have caused the debris in the oil to gradually increase.
If the oil goes directly into the lubricating oil circuit without being filtered, it will bring the impurities contained in the oil to the friction surface of the sports pair, which will accelerate the wear of the parts and reduce the service life of the engine. The role of the oil filter is to filter out the impurities, gums and moisture in the oil, and deliver clean oil to the lubricated parts.
Therefore, the oil filter element is indispensable when the engine is running. When selecting the filter element, the accuracy of the filter element should be selected according to the size of the impurities that can be entered. Filter out the large particles first, and then filter out the small ones one by one, which can prolong the life of the filter element, and make the impurities filter cleaner, greatly reduce the wear of parts, and extend the life of the engine.
