式真空ポンプ。 It has two impellers having a plurality of blades that are rotatably arranged in a cylindrical body, and a side plate that cooperates with the two blades of each impeller to form a chamber, and has both stages. In a two-stage water ring vacuum pump formed by arranging two impellers on the same axis, the first stage side is configured to supply gas to the impeller through a suction port and a discharge port that are in contact with the inner surface of the impeller. The second stage side is formed as a port cylinder type that pumps gas in the axial direction, and the second stage side is formed as a port plate type that pumps gas to the side of the impeller through a suction port and a discharge port that are in contact with the side surface of the impeller. A two-stage water ring vacuum pump characterized by:
