Structural principle of oil filter

Structural Principle

The oil filter mainly consists of three parts: filter element, filter material, and filtration volume. Filter element refers to a filtering material made of filter paper, usually made of cellulose fibers and synthetic fibers; Filter material refers to a filtering element composed of filter paper and surrounding skeleton, which is used to retain oil and impurities in it and prevent contamination of the engine interior; The filtration volume refers to the filtration space within the filtration unit composed of the filter element and filter material, which is the place where oil and impurities are separated during the process of oil passing through the filter element.

 

Working Principle

The working principle of an oil filter is to use a filter element and filter material to screen the filtered substances, preventing oil pollutants from entering the engine interior, in order to purify the engine oil and protect the engine. The filtration methods of oil filters include mechanical filtration, electrostatic adsorption, electrochemical separation, and other methods. Among them, mechanical filtration refers to the method of using the micropores and pore sizes of the filter element to block impurities, which is the most commonly used method for oil filters.
