Oil pump plays an important role in the fuel system of diesel engine. It is considered as the core of diesel engine lubrication system, which directly affects the overall performance of diesel engine, especially the technical effect and service life of diesel engine. Meanwhile, the processing of oil pump shell directly affects the production efficiency of oil pump manufacturing. By taking effective means to optimize the processing of oil pump shell, not only can greatly shorten the processing time, but also can effectively improve the manufacturing efficiency of oil pump, and bring more economic benefits for manufacturing enterprises.

In an automobile engine, the main function of the oil pump is to help the lubricating oil effectively establish pressure so that it can be delivered to all parts of the engine that require pressure lubrication. It is divided into wheel oil pump and gear oil pump. Gear oil pump has been widely used because of its advantages of simple structure, convenient processing, reliable operation, long service life and high pump oil pressure. At the same time, the oil pump is mainly composed of transmission gear, pump body, internal and external rotor, drive shaft, pump cover and pressure limiting valve. Its working principle is that when the engine starts running, the driving gear in the camshaft effectively drives the transmission gear on the oil pump and makes it rotate, thus fully driving the driven gear to reverse rotation [1]. This creates a low pressure in the intake chamber, which in turn creates pressure suction to draw oil from the sump into the oil chamber. At the same time, because the main and driven gears are always running, oil is continuously delivered to all parts of the engine that need lubrication.
