Oil pump shell with good sealing performance

Abstract

The invention discloses an oil pump shell with good sealing performance, belongs to the technical field of oil pumps, and aims to solve the problems that in the prior art, a filter disc is mostly mounted in an oil inlet pipe, impurities in oil are adsorbed and filtered by the filter disc, and due to the fact that the filter disc cannot be conveniently cleaned, more impurities are left on the surface of the filter disc, and adsorption and filtration of the oil are affected. Comprising an oil pump body, an oil pump shell and an oil tank, the oil pump body is fixedly connected with the oil pump shell, a limiting groove is formed in the outer wall of the oil pump shell, and an oil inlet pipe is fixedly arranged at one end of the oil pump shell; a rotating rod is driven to rotate, the rotating rod enables a rotating plate to rotate through a fixing sleeve, the rotating plate enables a soft brush to rotate, and the soft brush cleans impurities on the lower surface of a filtering disc, so that the impurities on the lower surface of the filtering disc are conveniently cleaned, and the convenience of cleaning the impurities on the lower surface of the filtering disc is effectively improved; and the influence of excessive impurities on the lower surface of the filter disc on oil adsorption and filtration is avoided.

Description

technical field [0001] The invention relates to the technical field of oil pumps, in particular to an oil pump casing with good sealing performance. Background technique [0002] Oil pump: The oil pump is a light and compact pump, which can be divided into three categories: inline type, distribution type and single type. The oil pump needs a power source to operate, and its lower camshaft is driven by the engine crankshaft gear. The oil pump proposes an oil pump with a housing made of aluminum-containing material and a movable molded part set in the housing. parts, wherein the movable molded part is at least partially made of a sinterable iron-based alloy material containing at least one austenite, and wherein the mold made of a sinterable material The article has a coefficient of thermal expansion that is at least 60% of the coefficient of thermal expansion of the housing. The oil pump housing in the prior art has the following problems: [0003] 1. At present, the insta...

Problems solved by technology

[0003] 1. At present, the installation of the oil pump casing and the fuel tank is mostly realized by bolts. Due to the need to turn the bolts repeatedly, the installation of the oil pump casing is inconvenient. At the same time, the sealing performance after installation is poor, resulting in the oil in the fuel tank Seepage from the outer surface of the oil pump housing;

[0004] 2. The oil in the oil tank enters the oil pump housing through the oil inlet pipe at the bottom of the oil pump housing. Since the impurities and dirt in the oil tend to remain on the inner wall of the oil inlet pipe, the existing technology cannot easily clean the dirt and impurities on the inner wall of the oil inlet pipe. , at the same time, long-term residual dirt and impurities affect the quality of the oil;

[0005] 3. In the existing technology, most of the filter discs are installed in the oil inlet pipe, and the impurities in the filter oil are absorbed by the filter discs. Since the filter discs cannot be cleaned conveniently, there are many impurities remaining on the surface of the filter discs. Affect the adsorption and filtration of oil. Therefore, we propose a well-sealed oil pump housing to solve the above problems
