The pump body makes noise
Thread Content
The new pump installed in our facility operates normally when the flow rate is 85 tons, but when the flow rate drops to around 50 tons, it produces a clicking noise, similar to the sound of cavitation. The material being transported is mainly tert-butanol containing ammonia. Could anyone please help analyze what’s causing this issue? Is it related to the quality of the pump?
How to reduce flow rate? What kind of pump is it?
Control must be carried out according to the parameters specified in the operating specifications; otherwise, abnormalities will occur. Such abnormalities include cavitation, gas entrapment, and pump overheating.
The flow rate is regulated by an outlet control valve; it’s a regular centrifugal pump
There is a high possibility that pressure buildup can cause vibration in the valve spool
For cavitation, it is recommended to lower the temperature of the medium at the inlet, use a frequency converter to start the motor, and adjust the motor’s speed in order to control the flow rate. This is for reference only
