The common shell materials of electric diaphragm pump are: plastic, aluminum alloy, cast iron, stainless steel, Teflon, etc. The commonly used materials of diaphragm pump diaphragm are: nitrile rubber, neoprene, fluororubber, polytetrafluoroethylene, polytetraethylene, etc. According to the power used by the actuator, the diaphragm pump can be divided into pneumatic, electric and hydraulic, that is, the pneumatic diaphragm pump with compressed air as the power source, the electric diaphragm pump with electricity as the power source and the electro-hydraulic diaphragm pump with liquid medium pressure as the power.

The structure of electric diaphragm pump is not complicated. For example, the more common electric diaphragm pump is mainly composed of explosion-proof motor, rack, engine crankshaft, crankshaft, crosshead, piston rod cylinder, diaphragm chamber, feeding product, feeding product, travel arrangement controller and steam regulated power supply. The total flow of raw materials can be controlled according to the travel arrangement controller. If there is a pressure problem, the machinery and equipment can not operate normally. Then, what's the matter when the diaphragm pump has no pressure? It can be checked according to the following aspects.

When understanding what the diaphragm pump is used for, we can strengthen our understanding by understanding the product structure, principle, application scenario and other information. At present, diaphragm pumps on the market are divided into pneumatic diaphragm pumps, electric diaphragm pumps, micro diaphragm pumps and so on according to different manufacturing processes.

Pneumatic diaphragm pump has five commonly used materials: plastic, aluminum alloy, cast iron, stainless steel and Teflon. Electric diaphragm pump has four kinds of materials: plastic, aluminum alloy, cast iron and stainless steel.

How many meters is the lift of diaphragm pump? At present, the mainstream diaphragm pumps are divided into pneumatic double diaphragm pump and electric diaphragm pump. Their performance parameters and application scope are slightly different. Taking the two diaphragm pumps currently available under Zhongcheng pump industry as an example, the lift can be as high as 30-40m, and the actual performance depends on the viscosity and specific gravity of the medium.
