Abstract: High-speed pump is a new type of centrifugal pump which is successfully developed based on new theory to transport small flow rate and high lift medium. At present, the technology of high-speed pump is still in the developing stage, and there is great room for improvement. The design of domestic high speed pump is relatively backward and needs to be improved in terms of low specific speed and optimization. In this design, a relatively simple structure of high speed pump can be improved by multistage speed regulation. Therefore, the efficiency of high speed pump can be improved effectively, and the weight and size of high speed pump can be reduced as much as possible. This design is aimed at improving the multistage drive design of high speed pump and improving the hydraulic performance and working stability of high speed pump. The research and development of the structure of high-speed pump is of great significance to the petroleum, aerospace and other fields of our country.
