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。

Abstract:Taking an impeller as the important component of mine submersible pump,the stress and deformation analysis of the impeller were carried out.The analysis can provide a reference for improving the performance of submersible pumps and optimizing the structure of the impeller so as to guide the design and production.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 axial stress and the first principal stress were far less than impeller material strength limit.The maximum deformation position is in the flow field between blades of front and back cover plates on the outer edge of an impeller.The analysis is favorable to analyse the reason for impeller deformation failure,as well as to check the impeller force and design rationality.The result provides a sufficient theoretical basis for the design optimization and modification of a mine submersible pump impeller.
