Polymer Additives in the Coolant of Water-Ring Vacuum Pumps

Abstract

Practice shows that vacuum water ring pumps are widely used in industry. Such pumps are used in almost all areas of the oil industry, metallurgy, chemical industry, mechanical engineering, food industry, agriculture, pulp and paper industry, gas and many other areas. Taking into account all the above-mentioned areas of application, the question arises about increasing the service life and reliability of LCVs (liquid water ring pumps). This article provides a fundamental study of the theory of operation and performance of a liquid ring pump. Keywords: vacuum pump, theoretical model, coolant, foaming, cavitation, actual performance.
