Hydraulic Optimization of Super-low Specific Speed Multistage Flameproof Submersible Pump with Inner Motor for Coal Mine

摘要：

Based on the design of one kind multistage flameproof submerge pump for coal mine, the influence of the geometric parameters to the performance of the impeller was analyzed. The performance of the pump was predicted by the commercial software FLUENT. Reynolds-averaged Navier-Stokes equations was discretized, solved with k-s turbulence model and the SIMPLEC algorithm in double coordinate system. The distributions of pressure and velocity in impeller were gained, which provide basis for the performance prediction, the hydraulic design and optimal design of super-low specific speed multistage flameproof submerge pump. The results show that pressure and efficiency change a lot as the impeller geometric parameters changes, and using CFD software can help us to improve and optimize the impeller design.
