The function of Electric Fuel Pump

The electric fuel pump consists of three parts: the pump body, the DC motor and the casing.

Its basic working principle is that after the DC motor is energized, the rotor in the pump casing is driven to rotate at a high speed, and the cut surface of the lower end of the rotor shaft is combined with the cut surface of the inner hole of the impeller, so that when the rotor rotates, the impeller is driven by the rotor shaft to rotate in the same direction.

During the high-speed rotation of the impeller, a vacuum and low pressure are created at the oil inlet, and then the filtered fuel is sucked from the oil inlet of the pump cover. out to provide fuel with a certain pressure to the fuel system.

The structure of the DC motor includes a permanent magnet fixed on the inner wall of the pump casing, a rotor capable of generating magnetic torque after being energized, and a graphite carbon brush assembly mounted on the upper end of the pump casing. The carbon brush is in elastic contact with the commutator on the armature rotor, and its lead is connected to the plug-in wiring electrode of the casing.
