Operation of water ring compressor with air duct

The article considers the features of determining the characteristics of water-ring compressors when they work with a pneumatic pipeline, in particular, the compression processes are taken into account. Applied load characteristics of compressor VK-3M1.The dependences of productivity on pressure are obtained, calculated on the conditions of injection with the assumption of an isothermal compression process using polynomials of the second and third order. Graphs of functions of dimensionless flow rate at the outlet of the pipe from the ratio of discharge pressure and atmospheric pressure are constructed. Calculations are carried out for different Mach numbers and generalized coefficients of hydraulic resistance of the pipeline.
