Reasons for no pressure in explosion-proof multistage pumps

15 Mar 2021Email

The explosion-proof multi-stage pump has the advantages of high efficiency and energy saving, wide performance range, safe and stable operation, low noise, long life, convenient installation and maintenance, etc.; by changing the material of the pump, sealing form and adding a cooling system, it can deliver hot water, oil, corrosion Sex and abrasive-containing media, etc. The explosion-proof multi-stage pump cannot reach the rated head if the pressure is not reached, and if the explosion-proof multi-stage pump fails to reach the head, it means that the explosion-proof multi-stage pump is invalid. So now let's get up and see what are the reasons why the explosion-proof multistage pump has no pressure!

Reasons why the explosion-proof multi-stage pump has no pressure:

1. The model of the explosion-proof multi-stage pump is not selected correctly, which fails to meet the production requirements;

2. The impeller of the explosion-proof multi-stage pump is damaged; the impeller is individually damaged. The impeller is the core part of the multi-pump, and its damage directly affects the head of the multi-centrifugal pump;

3. The shaft seal is damaged, causing the gap to be too large;

4. The inlet of the multi-centrifugal pump is blocked by debris;

5. The outlet pipeline is not smooth;

6. The shaft sleeve is worn, the gap is too large, and the pressure returns;

7. Motor problems, the rated speed cannot be reached, the motor voltage is insufficient, and the rated speed cannot meet the design requirements;

8. There is air leakage in the suction pipe of the explosion-proof multi-stage pump.
