Abstract

The article analyzes the flow gas-liquid mixture features inthe flow part of the impellers of multiphase stages pumping gas-liquid mixtures. By analogy with the coefficient specific speed of a pump for a single-phase liquid and the cavitation specific speed, a specific speed for multiphase pump stages is proposed. It is shown that the operation of blade pumps on multiphase media depends on the characteristics of the flow of the working fluid in all parts of the flow path, including the conditions at the inlet to the impeller, the flow in the blade cascade of the impeller, the guide vane, the outlet elements of the pump. Design changes in traditional blade cascades are recommended, and a new type is proposed: a multi-row cascade system.
