chemical centrifugal pump
What are the abnormal noises and vibrations of chemical centrifugal pumps?
There are mainly the following two factors that cause abnormal noise and abnormal vibration of the centrifugal pump.
​​​​​​​In terms of medium:
1. It is possible that the centrifugal pump sucks debris into its internal structure, causing blockage or damage to the impeller. At this time, shut down immediately and take quick cleaning at the same time;
2. The flow rate of the centrifugal pump has relatively large fluctuations, which leads to pressure changes, and then produces abnormal noise and abnormal vibration.
3. The suction stroke is too large, causing serious cavitation at the entrance of the impeller, that is, the water flowing on the impeller produces certain bubbles in the low-pressure zone, and these bubbles are destroyed in the high-pressure zone, which will produce Certain impacts, such impacts are more serious, and vibrations will find abnormalities. If this happens, the installation height of the centrifugal pump should be lowered.
