Working principle of gear oil pump: when the engine is working, the drive gear on the camshaft drives the drive gear of the oil pump to rotate the drive gear fixed on the drive gear shaft, thus driving the driven gear to rotate in the opposite direction, and sending oil from the oil inlet cavity to the oil outlet cavity along the backlash and pump wall. In this way, low pressure will be formed at the oil inlet cavity to generate suction, which will suck the oil in the oil pan into the oil cavity. As the driving and driven gears continue to rotate, the oil is constantly pressed to the required position. The function of the oil pump is to raise the oil to a certain pressure, and then force it to the moving surface of all parts of the engine. The structure of oil pump can be divided into gear type and rotor type. Gear type oil pump is divided into internal gear type and external gear type, and the latter is generally referred to as gear type oil pump.
