Centrifugal pumps produce high-frequency noise
Thread Content
When the centrifugal pump is in circulation mode, the return flow is enabled, and slight cavitation occurs; when the return flow is turned off, severe vibrations arise along with high-frequency noises. Could someone please tell me what causes this?
The centrifugal pump cannot operate in continuous full-cycle mode for an extended period of time, as the compressed liquid generates heat, which can cause the liquid to vaporize over time. If any unusual noises occur, use the normal sound as a reference. It’s not a noise coming from the equipment; it’s related to the manufacturing process. The current levels and all other process parameters are normal, so all that can be done is to keep a close eye on the situation.
