Oil pump

The function of the oil pump in the lubrication system: The oil pump acts to force the oil to a certain pressure and then forcibly press it onto the moving surface of each part of the engine. The structure of the oil pump can be divided into two types: gear type and rotor type. The gear type oil pump is further divided into an internal gear type and an external gear type, and the latter is generally referred to as a gear type oil pump.

Application

how do oil pumps work, a component used to force oil pressure and ensure a certain amount of oil to force oil to each friction surface. The internal combustion engine widely uses gear type and rotor type oil pump. The gear type oil pump has simple structure, convenient processing, reliable operation and long service life. The pump oil pressure is high, and the rotor pump body is widely used. It is complicated by powder metallurgy. This pump has the same advantages as the gear pump, but has a compact structure and small volume.

Working principle

The gear type oil pump is characterized by reliable operation, simple structure, convenient manufacture and high pump oil pressure, so it is widely used.

When the engine is working, the driving gear on the camshaft has the transmission gear of the motive oil pump, so that the driving gear fixed on the driving gear shaft rotates, thereby driving the driven gear to rotate in the opposite direction, and the oil is moved from the oil inlet chamber along the backlash. It is sent to the oil discharge chamber with the pump wall. In this way, a low pressure is formed at the inlet chamber to generate suction, and the oil in the oil sump is sucked into the oil chamber. As the main and driven gears rotate continuously, the oil is continuously pumped to the desired location.
