Discussion about Design of Front Guide Impeller of Axial Flow Pump

In order to mitigate the cavitations of the axial flow pump and improve the flow state of the main impeller, this paper gives a primary study on the design of the front guide impeller of the axial flow pump and its configuration. This paper address the determination and analysis of the parameters for the design of the front guide impeller, the determination of the guide impeller dimension and the calculation and diagraph of the shape of the guide impeller vane and so on. The guide impeller is designed to effectviely reduce the water vibration and noise of the axial flow pum
