摘　　要：为提高已有深井离心泵空间导叶的水力性能和制造工艺,设计了一种新型空间导叶,其设计原理来源于空间导叶和进口扭曲导叶设计方法.该导叶的叶片由扭曲部分和圆柱部分光滑链接而成,内盖板采用向内翻边的方式,使导叶注塑生产时可以轴向上下拔模,有利于规范化生产.以100QJ16型深井离心泵为例,按照L9(34)正交试验方案设计了多组模型,利用CFD软件对两级模型泵进行全流场数值模拟,研究了几个主要设计参数对新型导叶性能的影响规律.将优化的导叶模型进行了样机试验,具有较好的水力性能,在设计工况点,单级扬程4.25 m,效率67.62%,达到了设计要求.In order to improve the performance processing technology of deep-well centrifugal pumps, a new-type space guide vane was designed based on space guide vanes and entry twisted guide vanes. The blade of the new-type vane was smoothly linked from circumferential part and twisted part, and the guide vane was cast by inward flanging technique to overcome the difficulty in molding production and realize standardized production. Taking a deep-well pump of 100QJ16 as research object, the L9 （34） orthogonal experiment was performed. Based on CFD, the flow field of two-stage model pump was simulated, and four factors of geometrical parameters on head and efficiency were investigated. The optimum program was manufactured and tested. The head of the pump at rated flow point is 4.25 m with efficiency of 67.62% which can meet the design requirement.
