【 摘 要 】

The article presents the results of calculations of characteristics for water-ring pumps. Water-ring pumps are energy-saving and high-performance equipment, often used for pumping explosive gases or when working with flammable environ-ment. The design of water-ring vacuum pumps and compressors of many manufacturers is the same. The disadvantage of this type of compressors is their low overall efficiency. The algorithm and examples of determining the characteristics of compressor machines used in modern vacuum installations are considered. Based on the results of processing of experimental data of Erstevak ELRS models, empirical dependences and power consumption parameters are obtained. The isothermal efficiency of the liquid ring pump over the suction pressure has been normalized. Characteristics of isothermal power and efficiency are built. The dependence of the highest isothermal efficiency of the water ring pump on the performance (pumping speed) is obtained.
