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.
