Reasons for the output pressure of multistage centrifugal water pump not reaching the standard
If the pressure of the multi-stage pump is not reached, there is no way to reach the rated head. If the multi-stage pump fails to reach the head, it means that the multi-stage pump is invalid.
Multi-stage centrifugal pump output pressure does not meet the standard reasons:
1. The model of the multistage centrifugal water pump is not selected correctly, and it can not meet the production requirements.
2. The impeller of the multistage centrifugal water pump is damaged; the impeller is damaged individually. The impeller is the core part of the multistage pump, and its damage directly affects the lift of the multistage pump.
3. The shaft seal is damaged, resulting in an excessive gap.
4. The inlet of the multistage centrifugal water pump is blocked by debris.
5. The outlet pipeline is not smooth.
6. The sleeve is worn, the gap is too large, and the pressure returns.
7. The problem of the motor can not reach the rated speed. The motor voltage is insufficient, the rated speed does not meet the design requirements
8. Multi-stage centrifugal water pump suction pipe parts have air leakage phenomenon.
