Abstract The general equation group of variable-pitch screw line is analyzed first.According to the movement characters with non-constant axial-velocity of liquid-solid two-phase flow in the screw centrifugal impeller and the structure characters of screw centrifugal pump impeller,the vane profile parameter equation group for variable-pitch screw centrifugal pump is derived.Using the parameter equation group,the dependence on the design experience about screw centrifugal pump and the complicacy of segmenting the axial streamline for impeller are avoided,the CAD and numerical simulation of 3-dimensional flow field of this type of pump are also facilitated.screw centrifugal pump;variable-pitch;equation of vane profile;liquid-solid two-phase flow;impeller
