| Abstract: |
| Centrifugal pump vibration of a ship has great influence on ship operation. The possible causes of too strong vibration were put forward through analysis of tested vibration data and base on engineering practice. Improvement design was carried out on the pump using modern design method based on numerical analysis. Numerical simulation of the improvement design showed that the improved pump can run safely and steadily; liquid flow in the pump is relatively even; the running state under working condition is good. The waterpower performance of the prototype can meet the requirement of specification and the vibration is greatly reduced. |
