ABSTRACT
Helicoidal pump has excellent performance in production use.widely used in various fields of national economy. It was carried out exploratory design that combines the principles of ordinary screw and centrifugal pumps designed to meet the requirements of the product. The design process, I might appear on this pump structural problems and the problems faced by the actual use of the analysis and transformation, and the balance of axial and radial forces made a calculation and analysis. In the design of the structure process, choose the right form of structure, optimizing the parameters of the main components of strength check, to ensure that this pump has the reliability and practicality.
