Design method and characteristic analysis of Vortex pump

Based on calculation and measuring of the flow in vortex pump, the analysis of the influence of hydraulic and structural parameters on vortex pump's performance was carried out through experiment. Fifteen excellent hydraulic models were summarized and the design method involving statistical coefficient were obtained. The case of designing proved that the design method was practical and satisfying. Comparing of performance curves and cavitation property with common centrifugal pump of same specific speed was presented in this paper.
