Zusammenfassung:	The utility model relates to the technical field of vacuum pumps, in particular to a novel liquid ring vacuum pump, which includes a pump body, an impeller arranged in the pump body, a front side disk fixed at the front end of the pump body and a rear side disk fixed at the rear end of the pump body, wherein an air inlet and an air outlet are arranged on the front side disk; two flanges are arranged on the upper side of the front side disk; and the impeller includes a hub and blades key connected with the hub. The novel liquid ring vacuum pump is characterized in that the tail ends of the blades are opened to form blade points, and the gap between the impeller and the front side disk is 0.2 mm. When the novel liquid ring vacuum pump is in work, the water blades can be formed at the tail ends of the blades and the two ends of the impeller to completely wash away the scales and impurities inside the pump body and between the impeller and the front/rear side disks, thereby improving the working efficiency of the
