Abstract

The invention relates to an electric pump integrated fuel filter base assembly capable of automatically exhausting. The electric pump integrated fuel filter base assembly comprises a shell, a filter element assembly and an electric pump. The electric pump integrated fuel filter base assembly is characterized in that the shell comprises a bottom cylinder and an upper cover, wherein a first accommodating cavity is formed in the bottom cylinder; the upper cover is provided with a second accommodating cavity; the upper cover is provided with a plurality of groups of oil inlets and oil outlets; an iron net piece and an annular filter paper piece are arranged in the second accommodating cavity; the side portion of the oil inlet is connected with a reflux pipeline in a communicating mode; the end portion of the reflux pipeline extends to the side wall of the upper cover and is connected with the second accommodating cavity in a communicating mode; an exhaust pipe vertically distributed upwards is arranged in the middle of the reflux pipeline; an exhaust hole is formed in the end portion of the exhaust pipe; and copper sintering is distributed in the exhaust hole. The electric pump integrated fuel filter base assembly capable of automatically exhausting has the beneficial effects that the problem that in the prior art, an existing filter base assembly is difficult to exhaust is solved, the oil circulation rate is increased, and the filtering efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of filters, in particular to an electric pump integrated fuel filter base assembly capable of automatic exhaust. Background technique [0002] The fuel pre-filter is set in the engine fuel supply system, and is used to filter out impurities, water and other pollutants in the fuel, and then input it into the fuel delivery pump and fuel injector, so as to avoid excessive wear and tear of important parts such as fuel delivery pump and fuel injector. More or blockage and other problems to ensure the normal operation of the engine. [0003] The filter base assembly in the prior art has the following defects: [0004] (1) In order to improve the filtration of fine particles in the fuel filter, it is necessary to increase the density of the filter paper to reduce the passage of fine particles. After the density of the filter paper is increased, the air permeability between the filter paper is reduced, so that the...
