| Abstract: | The paper analyzes the flowing condition of the liquid in the impeller inlet of the centrifugal pump. Then it is suggested to adopt a fixed front inducer to improve the flowing condition of the liquid in the impeller inlet, in order to reduce hydraulic noise of fluid and at the same time to raise pump efficiency and improve its cavitation erosion property. |

| Keywords: | fluid machinery and fluid dynamic engineering centrifugal pump front inducer noise reduction |
