| To study the hydrodynamic performance of SPG50-200 type vertical canned motor pump for the basis of hydraulic model optimizing, commercial CFD software was used to simulate the internal flow in canned motor pump. The 3D modeling method and simulation method of flow field were introduced. Velocity of flow and pressure distributing in the pump were analyzed, and the hydraulic performance of the pump was predicted based on the results of flow simulation which were compared with the experiment results, the influence of the shape of volute cross section on the performance curve was investigated,the application prospects of the pump was introduced. It has certain significance guidance for improving the performance of the pump. |
