摘　　要：叶轮作为矿用潜水泵的重要部件,对其进行应力及变形分析,可为提高潜水泵的性能,优化叶轮结构,指导设计生产提供参考依据。利用有限元分析软件ANSYS 13.0,从矿用潜水泵实际运行工况出发,对潜水泵叶轮在耦合载荷作用下的应力及变形情况进行分析。分析结果表明:在耦合载荷作用下,叶轮径向、周向、轴向应力以及第一主应力远小于叶轮材料强度极限;最大变形位置在叶片与叶轮外缘前后盖板之间的流道上。该分析结果有利于分析叶轮变形失效原因,校验叶轮受力及设计合理性,并且为潜水泵叶轮的优化设计提供了充分的理论依据。Taking an impeller as the important component of mine submersible pump, the stress and deforma- tion analysis of the impeller were carried out. The analysis can provide a reference for improving the perform- ance of submersible pumps and optimizing the structure of the impeller so as to guide the design and produc- tion. Using finite element analysis software ANSYS 13.0, and starting from the mine submersible pump actual operation condition, the stress and deformation of a submersible pump impeller were analyzed in the mutual action of coupling load. The results showed that ： in coupling loading, impeller radial, circumferential and axi- al stress and the first principal stress were far less than impeller material strength limit. The maximum deform- ation position is in the flow field between blades of front and back cover plates on the outer edge of an impel- ler. The analysis is favorable to analyse the reason for impeller deformation failure, as well as to check the im- peller force and design rationality. The result provides a sufficient theoretical basis for the design optimization and modification of a mine submersible pump impeller.
