Prevent abnormal vibration and wear of the fire pump
The fire pump should be installed firmly, and its firmness should be checked regularly, especially the anchor bolts or backrest bolts, to prevent the fasteners from loosening;
Strengthen monitoring by monitoring the vibration waveform of the pump during operation, regularly check and repair the wear between the impeller and the sealing ring, and discover and eliminate hidden dangers in time; when the vibration of the pump is found to be abnormal after starting, it should be decisively analyzed for cavitation phenomenon, whether the impeller is balanced, whether the pump shaft and the motor shaft are concentric or whether the shaft has been deformed, and then take corresponding measures.
