CREATION OF A NEW GENERATION OF ENERGY-EFFICIENT TORQUE FLOW PUMPS IN THE CONTEXT OF THE STRATEGY OF INCREASE IN THEIR COMPETITIVENESS

Abstract

Due to their outstanding ability to pump liquids with inclusions, torque flow pumps have gradually become more and
more widely used in recent years. This became possible thanks to their low tendency to clogging and destruction under the
influence of abrasive particles, as well as increased service life. Nevertheless, this type of pump has certain disadvantages, the
most significant of which are low efficiency values, which usually do not exceed 58%.
This work considers the possibility of modernizing the flow part of the torque flow pump by increasing the width of its
impeller blades.
A numerical experiment conducted using the ANSYS CFX software showed that this modification of the design allows
us to get rid of the deformation of the toroidal vortex, increase the share of the blade work process in the torque flow pump. As
a result we get an increase in the head and efficiency of the pump installation.
As a result of the physical experiment, the hypotheses put forward in after the analytical study was verified. Also it
allowed us to confirm the results of the numerical experiments.
