Abstract

The paper explores the flow field characteristics of liquid Sodium pump, the flow field calculation model is established. The head and efficiency curves of sodium pump obtained by simulation are compared with the test data to verify the accuracy of the model. Flow characteristics inside the impeller, guide vane and the volute are investigated and summarized. The pressure distribution and velocity distribution characteristics of the steady flow field and the pressure fluctuation and fluid force characteristics of the unsteady flow field are further analyzed, which provides the basis for the calculation of flow induced vibration and sound field. The dynamic processes of Sodium cavitation effects are stimulated and studied systematically. The causes of fluid excited vibrations in Sodium pump are preliminarily revealed. Researches have remarkable guiding significances for the analysis of flow characteristics of Sodium pump system of the new generation 600 MW nuclear main pump system.
