1. Steps for installing the diaphragm pump

A. Before disassembling the diaphragm pump, mark the pump body and the air chamber on the left and right sides of the diaphragm pump respectively to facilitate subsequent reassembly operations.
B. Use a wrench to loosen the screw connecting the outlet pipe and the pump body. Remove the outlet pipe to see the ball and seat. Take out the ball and seat and check other spare parts of the pump. Check carefully for wear and chemical corrosion. Cracks and other phenomena.
C. Use a wrench to separate the outer pump body from the intermediate body of the internal test pump. After removing the pump body, the diaphragm and diaphragm clamp can be seen.
D. Use tools or wrenches to secure the left and right edges of the diaphragm outer splint to separate the diaphragm assembly from the intermediate body. Then turn the diaphragm device clockwise to release. After removing the outer splint of the membrane, the shaft was removed from the intermediate body.
E. Use a clamp (padded wood) to separate the shaft from the diaphragm unit and inspect the shaft, splint, and diaphragm for damage and corrosion.
F. The installation is sequentially performed from step E to step A.

2. How to choose the type of diaphragm pump

According to the power used, the diaphragm pump can be divided into three types: pneumatic diaphragm pump, electric diaphragm pump and hydraulic diaphragm pump.In addition, according to its functions and characteristics, there are solenoid valves, electronic, intelligent, fieldbus diaphragm pumps.

3. How to choose the characteristics of the diaphragm pump flow?

The choice of diaphragm pump flow characteristics can be calculated theoretically, but the methods and equations used are complex. At present, the experience criteria are often used, and the following aspects are considered: 1 from the adjustment quality of the adjustment system and selected; 2 from the process piping; 3 from the load change analysis.
