Annotation:

The authors of the article discuss the efficiency of gas separators operation as part of electrically-driven vane-type pumps (EDVTP) is analyzed. The scientific-technical literature within the framework of the research topic is analyzed as well. The main criteria for evaluating the efficiency of gas separators operation as part of electrically-driven centrifugal pump units are formulated. The main disadvantages of gravity, vortex and centrifugal gas separators are determined. On the basis of the conducted analysis the domestic design of the gas separator in the dimension group 5 was developed. The design of the gas separator includes screw-type impellers. The screw is presented in the form of a multi-pass axial impeller with a disk of the upper part, in which holes are made to increase dispersion of the gas-liquid flow. This design, in addition to separation properties, provides destruction of large gas phase bubbles. Bench tests of the developed design and standard gas separator were performed. According to the results of the bench tests the two gas-stabilizing devices were compared. The results and conclusions on the work performed were formulated.
