Oil pump (oil pump gear) means the engine can be achieved from moving parts of the oil sump to the main application is an important tool in the lubrication system. Pump After years of development and upgrading has also been relatively mature, has a good reputation in the user base. I believe speed up the pump works to further optimize and enhance the future of these products is very important. Then the pump working principle is how to achieve it?
Oil pump (oil pump gear) is characterized by a reliable, simple structure, easy to manufacture and high pressure oil pump, so widely adopted. When the engine is working, gear driven oil pump drive gear on the camshaft, secured to the pinion shaft pinion gear to rotate, thereby driving the driven gear rotates in the opposite direction of the oil from the inlet chamber along backlash and pump the oil to the chamber wall. Thus, the inlet chamber is formed at low pressure and create a suction to the oil sump of the oil sucked into the chamber.
Since the main, driven gear constantly rotating, oil will continue to be pumped to the required site. Oil Pump Application of the internal combustion engine more and more. Meanwhile, in the semiconductor, solar, LCD and other areas of engineering, also plays a role. With the development of processing technology, automotive oil pump - cycloid rotor pump is applied to the sewing machine, especially for some of the closed automatic lubrication system of the aircraft, such as sewing machine package, Beng sewing machine.
Oil pump (oil pump gear) with the processing convenience, high efficiency, long life, and high pressure oil pump, as the chemical, food, medical, industrial and other fields on the increasing demand for oil pump, oil pump has been developed multisectoral attention and care.
