Effect of gas content in the pumped liquid on the characteristics of a torque flow pump

Abstract

The article considers one of the ways to increase the ability of a dynamic pump to pump gas-liquid mixtures - the application of the vortex principle of energy transfer. This scheme is embodied in a torque flow pump, which is able to pump mixtures with a gas content of up to 0,40 - 0,45 without additional devices for preparing the mixture. Experimental researches the influence the value of the volumetric gas content on the performance characteristics of the torque flow pump of the "Turo" type are given. The analysis of influence of structure of a stream of gas-liquid mixture on the value of the critical gas content in the interblade channels of the impeller is represented and developed a physical model of decrease the parameters of the torque flow pump.
