THE RESEARCH OF THE TORQUE-FLOW PUMP OPERATING PROCESS WITH AN UNEVEN ARRANGEMENT OF THE IMPELLER BLADE SYSTEM

Abstract

Given the ever-increasing cost of energy resources in the world, the issue of efficiency in the use of energy equipment comes to the fore. At the same time, the pumping equipment itself is one of the main consumers of electricity in the world. The average rate of electricity consumption by pumping equipment by economic sector is about 20%, including up to 50% in certain sectors of the economy. Thus, reducing the energy consumption of pumping equipment by increasing its energy efficiency is one of the important issues regarding the achievement of the UN Sustainable Development Goals (in particular, SDG 6 "Clean water and sanitation", SDG 7 "Affordable and clean energy", SDG 9 "Industry, innovation, infrastructure") The main advantages of torque-flow pumps using are their simplicity of design, increased service life and lower probability of contamination compared to centrifugal analogues. However, the use of pumps of this type is associated with the transportation of liquids with various types of inclusions. This can lead to negative consequences in the form of clogging of passage channels, reduction of productivity, energy efficiency of torque-flow pumps. The article is devoted to the development of an effective mechanism for preventing the clogging of pumps of this type, which will significantly increase the energy efficiency of the pumping equipment and increase its service life
