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 the filtered fuel is sucked from the oil inlet of the pump cover.
