FIELD: mechanical engineering; pumps and compressors.
SUBSTANCE: proposed two-stage liquid-ring machine contains housings of first and second stages, end face covers and drive shaft. Sectional design working wheel is common for two stages. Housing of second stage is arranged with eccentricity relative to axis of machine. Places where blades pass second stage housing are provided with hinged seals. Housing are rotated by drive shaft of second stage.
EFFECT: reduced overall dimensions, increased capacity and efficiency and reduced consumption of energy for evacuation.
