Structural principle​                                                                             

    In the modern car with a variety of different gasoline injection system, their fuel supply is also different, but must have an electric fuel pump. Its main task is to supply the fuel system is sufficient and have a certain pressure of fuel.
    As the mechanical diaphragm fuel pump, by the structural constraints, the installation location is both away from the heat source but also inline type can not be set. The electric fuel pump position can be arbitrarily selected, and has no air resistance characteristics.
The structure of the electric fuel pump consists of three parts: pump body, permanent magnet motor and shell. Permanent magnet motor that drives the pump body rotation, the fuel from the inlet inhaled, flowing through the internal fuel pump, and then from the oil out of the mouth, the supply of fuel oil. Fuel flow through the internal electric fuel pump, the permanent magnet motor armature to play a cooling effect, also known as wet fuel pump.
   The motor portion of the electric fuel pump includes a permanent magnet fixed to the housing and an armature generating an electromagnetic moment and a brush device mounted on the housing. The brush is in contact with the commutator on the armature and its lead is connected to the post on the housing to control the voltage of the electric fuel pump to the armature windings. The electric fuel pump's shell is crimped at both ends so that the components are assembled into a non-removable assembly.
The additional function of the fuel pump is completed by the safety valve and check valve. The safety valve can avoid excessive pressure rise when the fuel line is blocked, causing the tubing to break or the fuel pump damage. The purpose of the one-way valve is to seal the oil circuit when the fuel pump stops working, so that the fuel system to maintain a certain residual pressure, so that the next start the engine easy.
   The pump body is the main body of the electric fuel pump pump oil, according to its different structure can be divided roller and flat blade type. The most common roller type electric fuel pump.
   The electric fuel pump is installed in the car and installed outside the fuel tank and outside the fuel tank. There are a few models in the fuel tank, the installation of an electric fuel pump, both in series on the oil.
