Problems solved by technology

However, in order to prevent the filter element from being clogged or the oil viscous during cold start, most of the existing filters are equipped with a relief valve to ensure the supply of oil, but when the relief valve is opened, the oil will directly enter the engine without being filtered by the filter element. It will even take away the large particles of impurities filtered out by the original filter element, causing secondary wear and tear.

Abstract

The invention relates to the field of engine oil filtering equipment, in particular to an engine oil filter equipment capable of automatically replacing filter paper. It includes: a shell, a threaded cover, a check valve, an upper end cover, a filter element, a power rod, a secondary filter, and a planetary mechanism; the shell is cylindrical, and an overall space is formed by a threaded cover; the check The valve is made of rubber material and installed on the threaded cover to prevent oil from flowing backward. The invention has a simple structure. By storing the clean filter paper in advance and unfolding it when needed, the service life of the oil filter can be effectively improved and secondary wear can be prevented.

Description

technical field [0001] The invention relates to the field of engine oil filtering equipment, in particular to an engine oil filter equipment capable of automatically replacing filter paper. Background technique [0002] When the engine is working, the metal wear debris produced on the friction surface of the parts, the dust in the atmosphere, and the carbon particles produced by incomplete fuel combustion will all penetrate into the engine oil, and the engine oil itself will also produce colloidal deposits due to thermal oxidation. These impurities will be mixed in the engine oil. in engine oil. If such dirty engine oil is sent directly to the surface of moving parts, the mechanical impurities in the oil will become abrasives, which will accelerate the wear of parts, and cause blockage of oil passages and cementation of piston rings, valves and other parts. [0003] Therefore, an oil filter must be installed in the lubrication system to purify the circulating oil before it ...
