Abstract:Pump is the core power source of the fluid conveying system. It has been a research focus in the field of fluid machinery to carry out the optimal design of pump and realize energy saving and consumption reduction. In recent years, many scholars at home and abroad have carried out systematic and in-depth research on the pump optimization design technology, and accumulated abundant practical experience in the design of the impeller, guide vane and volute of the pump individually or as a whole. This paper reviews the methods of hydraulic design based on the theory of one, two and three elements, summarizes the advantages and disadvantages of each optimization method, summarizes the recent research and leading methods for the hydraulic design of impeller, guide vane and volute in recent years, and lays a foundation for the development of pump design methods in the future. The design method of numerical simulation combined with three-dimensional theory and optimization algorithm has become the mainstream means of pump optimization design. It can be expected that with the improvement of computing power of large-scale computer and the development of optimization algorithm, the level of hydraulic design of pump will be greatly improved and the overall technical progress of pump industry will be promoted.
Keywords:pump   impeller   guide vane   hydraulic dulic design   numerical simulation
