The role of oil pump in the lubrication system: the role of oil pump is to increase the oil to a certain pressure and then forcibly press 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 called gear type oil pump.

It is used to increase the oil pressure and ensure a certain amount of oil to supply oil to the friction surfaces. Gear type and rotor type oil pumps are widely used in internal combustion engines The gear type oil pump has simple structure, convenient processing, reliable operation, long service life and high pump oil pressure, and is widely used. The rotor of the rotor pump is complex and is mostly pressed by powder metallurgy. This pump has the same advantages as the gear pump, but it is compact in structure and small in volume.
