【 摘 要 】

This article discusses centrifugal pumps with half-open impellers. One of the two most important parameters of a centrifugal pump is its resource and efficiency. However, often the race for efficiency leads to such constructive solutions that help reduce the pump life and vice versa. The solution of such problems is attributed to multicriteria optimization, one of the methods of which is to build a trade-off curve. In this paper, this curve is constructed using the application of such methods as the LP-Tau search method. The variable parameters in this article are axial clearance and rotor speed.
