The role of the oil pump in the lubrication system:
The function of the oil pump is to raise the oil to a certain pressure and force the ground pressure to the moving surface of the engine parts. The structure of oil pump can be divided into two categories: gear type and rotor type.
Gear type oil pump is divided into internal gear type and external gear type, generally referred to as the latter gear type oil pump.
Structural characteristics of oil pump:
Simple structure, small size, light weight, large oil transmission. Cycloidal rotor pump system adopts the structure of internal and external rotor meshing, the number of teeth is small, the structure size is compact, and the sealing cavity can be formed without other isolation elements, and the number of parts is small.
What is the working principle of oil pump?
When the engine is working, the drive gear on the camshaft with the transmission gear of the motor oil pump, so that the drive gear fixed on the drive gear shaft rotates, thereby driving the driven gear to rotate in the opposite direction, the oil from the oil inlet cavity along the backlash and pump wall to the oil outlet cavity.
In this way, a low pressure is formed at the oil inlet chamber to produce suction, which sucks the oil in the oil pan into the oil chamber.
Due to the continuous rotation of the main and driven gears, the oil is constantly pressed to the required part.
