ZX self-priming centrifugal pump has the advantages of compact structure, convenient operation, smooth operation, easy maintenance, high efficiency and long service life.

Failure causes of stainless steel self-priming centrifugal pump:
1. ZX self-priming pump does not produce water.
The main results are as follows: 1. There is no liquid storage or insufficient liquid storage in the pump cover.
2. Air leakage in the suction pipe.
3. The rotational speed is too low.
4. The suction distance is too high or the suction line is too long.
5. The leakage of mechanical seal is too large.
6. The gas in the suction line cannot be discharged from the outlet.

2. ZX self-priming pump has a large noise and vibration.
1. The soles of the feet are unstable.
2. Bending of pump shaft.
3. Cavitation phenomenon.
4. Serious bearing wear.
5. There are sundries in the inlet pipeline.
6. The spindle of pump is different from that of electric motor.

Third, the method of self-suction and discharge of stainless steel:
1. Add enough liquid to store liquid.
2. Check and eliminate the phenomenon of air leakage.
3. Adjust the report.
4. Reduce the suction distance or shorten the suction line.
5. Repair or swap.
6. Make it excluded.
7. Reinforcement.
8. Replace or correct.
9. Adjust the working conditions.
10. Replace.
11. Get rid of sundries.
12. Adjust coaxiality
