The role of the oil pump in the lubrication system: The function of the oil pump is to force the oil to a certain pressure and then force it to 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.
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 oil 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.
Application
There are more and more applications of oil pumps on internal combustion engines. At the same time, it also plays a certain role in the fields of semiconductor, solar energy, LCD and other engineering fields. With the development of processing technology, the automotive oil pump, the cycloidal rotor pump, is applied to the sewing machine, especially for some fully enclosed automatic lubrication systems, such as overlock sewing machines and stretch sewing machines.
