As a new kind of sewage pump, the screw centrifugal pump combines the advantages of screw pump and centrifugal pump. Compared with the traditional sewage pump, this new type of screw centrifugal pump demonstrates a better performance, such as less abrasion, damage and higher efficiency. It is prospective to investigate more deeply on the screw centrifugal pump. In the past, the screw centrifugal pump usually was designed by the one-dimensional theory, the hydraulic design process is similar to a normal centrifugal pump. However, because of the long trap angle and blade rotation, it is easy to commit errors in the one-dimensional design process. In this study, the general blade screw lines of hub and shroud are analyzed. The profile equations of blade screw lines were established using polar coordinate. The entire design process was discussed in detail. Moreover, the computational fluid dynamics (CFD) method has been adopted to conduct numerical simulations to investigate the internal flow characteristics of the screw centrifugal pump model and validate the performance of the newly designed screw centrifugal pump model.
