摘要：
To improve the property of jet self-priming centrifugal pump, a jet self-priming centrifugal pump with specific speed of 34 was used as the research object to compare and analyze the external and noise characteristics of the impeller on the conditions of 6 blades (6 long blades) and 8 blades (4 long blades and 4 short blades) from numerical simulation and experiment. Based on the pump test system and data acquisition system, a test system of the jet self-priming centrifugal pump was established to realize pump performance parameters and internal field noise signals synchronization acquisition. The results show that under rated conditions, the head and efficient of optimization model are increased respectively 12.6% and 0.8% than the original model. The internal hydrodynamic noise decreases by 1.6% and the exterior hydrodynamic noise decreases by about 2%. © 2019, Central South University Press. All right reserved.
