【 摘 要 】

The article deals with the problems associated with the analysis of high-speed low-flow centrifugal pumps. The existing methods for analysis of such pumps and their disadvantages were reviewed. A method of multi-criteria optimization of high-speed centrifugal pumps has been proposed. The method is based on the search for a compromise between the cavitation characteristics and the hydraulic head of the centrifugal pump by plotting a compromise curve. The LP-tau searching method was used for finding the points of this curve in the article. The LP-tau search in the article was carried out by two design parameters - the rotor speed of the centrifugal pump and the diameter of the impeller blades.
