Abstract

The invention discloses a universal spin-on filter adopting a two-stage integrated composite filter element, which includes a shell and a filter element arranged inside the shell. The filter element includes an upper end cover, a lower end cover, filter paper and polyamide melt blown The mouth of the shell is provided with a threaded connecting plate, and a number of oil inlet through holes are arranged around the threaded through hole of the threaded connecting plate, and the oil entering the oil inlet pipe of the filter seat enters the shell and Between the filter elements; the outer edge of the threaded connecting plate is provided with a number of symmetrically distributed protruding teeth, and the mouth of the housing is provided with a groove matching the protruding teeth. The circumferential scale of the protruding teeth is smaller than that of the groove. The bottom of the body is provided with an elastic support, and under the action of the elastic support, the threaded connecting plate is pressed between the mouth of the housing and the oil outlet of the filter element. The invention solves the problem that the filter element in the existing filter housing cannot be replaced, has the characteristics of strong dirt holding capacity, high filtering precision, and is suitable for filtering various oil products.

Description

technical field [0001] The invention belongs to the field of machinery and relates to an oil filter, in particular to a filter with a replaceable filter core and a reusable shell. Background technique [0002] During the production, transportation and storage of engine fuel, a large number of impurities will be produced and mixed. Clean fuel oil will also produce pollutants such as metal oxides, precipitated colloids, and asphaltene after storage for a period of time. Severely polluted fuel will cause wear and carbon deposits in the engine fuel injection system and combustion chamber, which will increase the fuel consumption and exhaust emissions of power equipment after a period of use. The current general solution is to install an oil filter on the engine to remove impurities, colloids, asphaltene and moisture in the oil to make the oil clean. Clean oil can improve combustion efficiency, thereby saving fuel and reducing emissions; it can also reduce abnormal wear and tea...
