Beschreibung
Zusammenfassung:	The utility model belongs to the technical field of vacuum pumps, and particularly relates to a liquid ring vacuum pump device which comprises an impeller and an integrated pump structure, the upper portion of the pump structure is provided with an air suction cavity and a discharge cavity, the lower portion of the pump structure is provided with a compression cavity, and a shaft hole penetrating through the inner top wall of the compression cavity downwards is formed between the air suction cavity and the discharge cavity. The shaft hole is eccentrically formed relative to the center of the compression chamber, the shaft hole downwards penetrates through the inner top wall of the compression chamber, and the inner top wall of the compression chamber is provided with an air suction flow distribution hole communicated with the air suction chamber, a discharge flow distribution hole communicated with the discharge chamber and a liquid inlet channel extending to the outer surface of the pump structure to form a
