摘　　要：在分析B型双螺杆泵原螺杆螺旋型线不足的基础上,提出了型线的改进,并通过密封性分析,证明改进之后属于密封型螺杆泵.此外,对改进的螺杆螺旋端面齿形及理论流量作了相关计算,得出改进后的实际流量将会增加的结论.所列出的轴截面的主要数据,为制作检验用样板提供参考.In this paper the former line＇ s deficiency of type B double screw pump has been analysed, then the paper put forward the improved model. By the sealing analyses, the double screw pump has been proved to belong to the sealing type after the improvement. By the calculation, we came to the conclusion that the actual pump capacity would be increased. At last there was a list of the main shaft section for making inspection data, providing with reference data model.
