变角螺旋线在扭曲叶片设计中的应用

Application of Variable Angle Helix on the Design of Twisted Vane

采用变角螺旋线法对固液两相流渣浆泵扭曲叶片进行了尝试性设计,并初步总结了其设计方法和规律。在实际应用中对泵效率产生了有益的影响。

The paper makes trial design to the twisted vane of pump which is used for slurry containing solid slag by variable angle helix method and generally concludes the design method and rule, which proves to be beneficial to the efficiency of pump in practice.
