LIQUID RING MACHINE Russian patent published in 2021 - IPC F04C7/00 F04C19/00 

FIELD: pump and compressor engineering.

SUBSTANCE: invention relates to pump and compressor engineering and allows to reduce power consumption, increase productivity, the depth of the vacuum achieved for single-stage liquid-ring machines. The liquid-ring machine contains a stationary cylindrical body 1, placed in it with eccentricity and the possibility of rotation of an impeller 8 with blades 9 on a stationary camshaft with a partition forming an input pipe at one end of the shaft and an output pipe at the other. Outside the housing 1 is a three-phase electrical winding 12. Inside the housing 1, a ferromagnetic sleeve 11 with blades 10 is installed with the possibility of rotation when an electric voltage is applied to the winding 12.

EFFECT: invention is aimed at increasing the efficiency of the liquid ring machine.
