Generally, after 1500 hours of continuous operation of diaphragm pump, there will be pressure relief, leakage medium and other problems. Check the pump body. If there is no problem, we can solve the problem of leakage by replacing the diaphragm. Generally, the leakage of pump body has the following situations:

1. If there are solid substances in the pump body, hot water can be used to clean it. Before disassembling the diaphragm pump, mark the pump body and air chamber on the left and right sides of the pump respectively for subsequent reassembly;

2. Use a wrench to loosen the screw connecting the outlet pipe and the pump body. Remove the outlet pipe to see the valve ball and valve seat. Take out the summation seat and check other spare parts of the pump, and carefully check whether there are abrasion, chemical corrosion and cracks;

3. Use a wrench to separate the intermediate of the outer pump body and the inner pump. After the pump body is removed, the diaphragm and diaphragm splint can be seen;

4. Use tools or spanners to fix the left and right edges of the diaphragm outer splint to separate the diaphragm device from the intermediate. Then rotate clockwise to loosen the diaphragm device, remove the diaphragm clamp plate, and take the shaft out of the intermediate.

5. Separate the shaft from the diaphragm device with a clamp (pad board), and check whether the shaft, splint and diaphragm are damaged and corroded.

If these can not solve the problem of pump body leakage and other problems, about the diaphragm, then you can contact Hebei Xinglong Baiye to provide you with free inspection service of cloth diaphragm
