摘　　要：叶轮与蜗壳是离心泵重要的组成部分,它们的制作精确程度和耦合性直接影响离心泵水利性能。为能更好地改善叶轮与蜗壳耦合处产生的流动损失,以Pro/E为设计平台,提出叶轮木模图及蜗壳二维投影图的分析及测绘方法,结合Pro/E中"偏移坐标系基准点"等命令,实现叶轮扭曲叶片及蜗壳的实体精准造型,并通过Fluent进行数值模拟。压力和速度分布图显示叶轮与蜗壳耦合处压力和速度呈均匀规律性变化,扬程计算显示符合设计要求。分析结果证明,此种绘图方式不仅精确、快速、灵活,还能够改善叶轮与蜗壳耦合处的流动损失,为后续流场数值分析奠定基础。The impeller and volute are important parts of centrifugal pump.Their degree of precision and coupling production directly affect the performance of centrifugal pump water conservancy.In order to improve the flow loss generated atthe impeller and volute coupling,Pro/E is taken as the design platform.the analysis and mapping method of impeller and volute Wooden patterns 2-D projection are put forward.Combined with Pro/E in the ＂offset coordinate datum point command＂ commands,the twisted blade and volute impeller entity modeling precision are realized through Fluent numerical simulation.The pressure and velocity distribution of impeller and volute coupling shows that pressure and velocity are uniform regularity,and head of delivery calculation shows that the design requirements meet design requirement.The analysis results show that this method is not only drawing accurate,but also is fast and flexible,and it can improve the flow loss of the coupling of the impeller and the volute,which lays the foundation for further numerical analysis.
