[0002] A pump is a machine that transports fluids or pressurizes fluids. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increasing the energy of the liquid. Pumps are mainly used to transport liquids such as water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals. They can also transport liquid-gas mixtures and liquids containing suspended solids. Pumps can usually be divided into three categories according to their working principles: positive displacement pumps, dynamic pumps and other types of pumps.

[0003] Among them, the pump cover of the chemical drainage pump is an important component of the drainage pump. When the drainage pump is working, the liquid enters from the liquid inlet of the pump cover and is discharged from the liquid outlet of the pump cover. Therefore, the structural performance of the pump cover directly affects the operation of the drainage pump.

[0004] The existing pump cover cannot be installed on the corresponding pump when it is installed, which makes it easy to install pump covers of different specifications on the pump by mistake, causing the pump to fail to work properly. Utility Model Content
