Abstract

The invention discloses a two-stage oil absorption electric fuel pump with jet. The pump comprises a motor, a pump body and a shell, wherein the motor and the pump body are arranged in the shell; the pump body comprises an oil outlet plate, a secondary impeller, an oil inlet plate, a primary impeller and a pump cover; the oil outlet plate is arranged on the motor through an oil bearing; the secondary impeller is positioned between the oil outlet plate and the oil inlet plate; the primary impeller is positioned between the oil inlet pipe and the pump cover; and one end of the shell is provided with an oil outlet. The two-stage oil absorption electric fuel pump with the jet has a simple structure, low cost and high effective output power.

Description

technical field [0001] The invention relates to an electric fuel pump, in particular to a two-stage oil-suction electric fuel pump with jet flow. Background technique [0002] The electric fuel pump is installed in the fuel tank of the car and immersed in the fuel. It is an important part of the electronically controlled fuel injection system of the car engine. [0003] In the existing electric fuel pumps with jets, the pump body usually adopts a metal structure, which is very expensive, and because it is made of metal materials, the load on the entire oil pump motor is too large, reducing the effective output power of the motor ; Moreover, the jet device and the pump body are split, which increases the processing difficulty and complexity of the pump body. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a two-stage oil-suction electric fuel pump with jet, which has simple structure, low cost and high effective ...
