摘　　要：螺旋离心泵是一种防堵塞性能优秀、高效区宽广以及功率曲线平坦的单叶片杂质泵,主要应用于食品输送、污水处理和制浆造纸领域.但目前该泵设计方法尚不成熟,较为依赖设计者的设计经验,同时传统的螺旋离心泵水力模型设计方法和绘制过程较为陈旧,这也造成该种泵设计效率普遍不高,设计成本较大.因此本文通过研究现有螺旋离心泵的设计方法,对现有经验公式进行修改,并使用CFturbo和SolidWorks相结合的方法对螺旋离心泵水力模型进行开发.该方法能够明显简化设计流程,且设计出的泵水力性能较好,数值计算显示,该方法设计的比转速为145、包角为600°的螺旋离心泵优化后设计工况点的水力效率达到73.83%,最佳工况点的水力效率达到75.95%.The screw centrifugal pump is a single-blade impurity pump with excellent anti-clogging performance,wide highefficiency area,and flat power curve.It is mainly used in the fields of food transportation,sewage treatment,and pulp and paper.However,the design method of the pump is still immature and relies on the designer's design experience.At the same time,the traditional spiral centrifugal pump hydraulic model design method and drawing process are relatively old,which also causes the design efficiency of this pump to be generally low and the design cost is relatively large.Therefore,by studying the design methods of existing spiral centrifugal pumps,this paper modifies the existing empirical formulas,and uses the method of combining CFturbo and SolidWorks to develop hydraulic models of spiral centrifugal pumps.This method can obviously simplify the design process,and the designed pump has good hydraulic performance.Numerical calculations show that the hydraulic efficiency of the design working point after the optimization of the spiral centrifugal pump with a specific speed of 145 and a wrap angle of 600°is reached 73.83%,the hydraulic efficiency of the best working point reaches 75.95%.
