Problems solved by technology

However, since this kind of oil filter can only filter out impurities with large particle sizes, it is difficult to filter out wear impurities with small particle sizes, which also reduces the service life of the engine.

Abstract

The invention provides an oil filter with multiple filter elements. The oil filter comprises a shell, a bottom plate, a first filter element and multiple second filter elements. Oil in an engine can respectively flow in second central pipes of multiple second filter elements from multiple oil inlets; after metal filling is magnetically adsorbed by magnetic filtration modules of the second central pipes, the oil is filtered for the second time by a second filter paper group and then flows in the inner chamber of the shell; after being filtered by a first filter paper group, the oil flows in a first central pipe through a first through hole and finally flows back into the engine through a first oil guide hole and an oil outlet. The metal impurities of varying sizes are filtered in an adsorbing mode by multiple magnetic filtration modules in multiple second filter elements, therefore the filtration pressure of the first filter paper group and the second filter paper group is reduced, the service cycle of the first filter paper group and the second filter paper group is prolonged, and the filtration effect of the first filter element and the second filter elements is improved. The metal impurities adsorbed by the magnetic filtration modules can completely stay in the second central pipes and cannot flow in the inner chamber of the shell along with the oil.

Description

technical field [0001] The invention relates to the technical field of oil filters, in particular to a multi-filter element oil filter. Background technique [0002] The function of the oil filter is to filter the oil entering the main oil passage of the engine, so that the oil can reach a certain degree of cleanliness, and prevent the early abrasive wear of the moving parts in the engine due to impurities. When the engine is running, the oil with a certain pressure It enters the filter through the oil inlet hole, and after being filtered by the filter element assembly, it enters the lubricating mechanism of the engine through the oil outlet hole. But because this kind of oil filter can only filter out the impurities with larger particle size, it is difficult to filter out the wear impurities with smaller particle size, which also reduces the service life of the engine. Contents of the invention [0003] Based on the technical problems in the background technology, the pr...
