Abstract

The invention relates to the technical field of electric pumps, and discloses an electric pump with signal control. The electric pump with signal control comprises an upper cover and a pump cover, wherein a positioning support is arranged in the pump cover, a filter screen is arranged at the bottom of the pump cover, a valve element is movably connected to the surface of the positioning support, the end, far away from the positioning support, of the valve element is connected with the filter screen, a valve support is movably connected to the joint of the valve element and the filter screen, a valve spring is movably connected to the surface of the valve support, and the end, away from the valve support, of the valve spring is fixedly connected with the valve element. The valve support and the pump cover are installed in interference design, the edge is extruded to generate a barb to limit the valve support, and fuel oil is filtered through the filter screen; when the pressure of the fuel oil in the pump is too high and reaches the pressure value set for the valve spring during working, the valve element is jacked open to release pressure and discharge oil through an oil drainage hole, and the pressure in the pump is controlled to be safe; and by means of the design, a sealing ring and a limiting device do not need to be additionally arranged, the reliability of the valve is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of electric pumps, in particular to an electric pump with signal control. Background technique [0002] The electric pump is a common driving component. The existing electric pump will be applied on the fuel filter. Its components are: integrated controller without over-line stator, rotor, positive displacement pump (roller type, Chip type, scroll type) pressure relief valve, filter screen, external input port, support frame and sealing ring, filter and heater and other filter accessories. [0003] The internal parts of the existing electric pump will have poor sealing performance due to the aging of the sealing material and the sealing ring breaking away from the empty groove; It is unreliable and the manufacturing cost is high, so an electric pump with signal control came into being. Contents of the invention [0004] The purpose of the present invention is to provide an electric pump with signal contr...
