Shenyang Pump Manufacture Co., Ltd.'s analysis on causes of cavitation of condensate pump includes the following aspects:
(1) Excessive change in water level.
(2) Negative pressure in pump inlet piping
(3) The inlet pipe of the pump is in poor oblique angle for a long time.
(4) Excessive temperature variation of mixed liquid.
(5) No pressure relief valve installed at pump inlet.
Treatment of cavitation of condensate pump
For cavitation of condensate pump, we shall take the following measures:
1. Check the inlet and outlet of cleaning pump regularly.
2. Replace the damaged impeller and pump case in time.
3. Install pressure relief valves to ensure pump is operating at normal pressure.
4. Repair or replace damaged bearings or mechanical seals in a timely manner.
5. Ensure that the equipment at the inlet of the pump is in good condition without negative pressure or backflow.
Suggestions for maintenance
In order to avoid cavitation of condensate pump, we also need to pay attention to the following aspects:
1. Regularly check and clean the pump body to ensure that there is no sediment in the pump body.
2. Replace the parts in the pump body as required to ensure the normal operation of the pump.
3. Strictly control the temperature change in the medium to avoid sudden temperature change.
4. Replace the pressure reducing valve regularly to ensure that the pump operates under normal pressure.
5. Ensure that the equipment at the pump inlet is in good condition without negative pressure or backflow.
In a word, for cavitation problem of condensate pump, we should take timely measures for repair, and carry out regular maintenance to avoid the problem.
We welcome your call and consult Shenyang Pump Manufacture Co., Ltd. and look forward to your cooperation!
