as a new kind of impurity pump, screw centrifugal pump combines the advantages of screw pump and centrifugal pump, and the special structure can bring into play their advantages sufficiently.
螺旋离心泵作为一种新型杂质泵,将螺旋泵与离心泵融合为一体,其独特的结构可将两者的优势充分发挥。
structure and performance of a screw centrifugal pump used in aero-engine was discussed in this paper. and the calculation method of the pump's performance was also given out.
