Cause analysis of noise in internal gear pump

(1) Pump flow pulsation causes noise. In the process of operation, the pump is faced with the noise problem caused by flow pulsation phenomenon, and the possibility of flow pulsation being eliminated in the process of pump operation is very low. The results show that the flow pulsation of...
