| Abstract: | In view of the large vibration of marine centrifugal pumps,the vibration testing data of the equipment are analyzed.Based on the characteristics of centrifugal pumps and engineering practices,the paper summarizes the reasons for vibration and puts forward some countermeasures.Based on the modern design method with flow simulation by CFD,the centrifugal pump is redesigned for vibration reduction.The result shows that the inside hydro-borne instability of the pump is largely improved. |
