LIQUID-RING MACHINE Russian patent published in 2022 - IPC F04C7/00 F04C19/00 

FIELD: compressor equipment.

SUBSTANCE: invention relates to compressor equipment and vacuum technology, specifically to liquid-ring machines. The machine contains a housing 1, end caps with suction and pressure windows for the gas medium and an eccentricity-mounted shaft 5, on which the impeller 6 with blades is located. The pressure window 4 is equipped with a mechanism for regulating the size of the flow section. Rigidly fixed blades 7 are located on the inner cylindrical surface of the housing 1, providing the transmission of rotation to the housing 1 from the impeller 6. The blades of the impeller 6 are reinforced with knee-plate bandages. Fittings for additional supply of working fluid are installed in the suction area. The flow rate of the additionally supplied working fluid is a function of the cross-sectional area of the pressure window and the temperature of the liquid in the working cavity.

EFFECT: invention is aimed at improving the reliability and efficiency of a liquid-ring machine.
