Abstract: The invention provides a liquid ring pump blade wheel, and relates to the technical field of water pump accessories. The liquid ring pump blade wheel is characterized in that the outer side of the hub (1) is provided with a plurality of long blades (2), short blades (3) are arranged between the adjacent two long blades (2), and the short blades (3) and the long blades (2) are fixedly connected through reinforced rib plates (4). According to the present invention, the short blades are additionally arranged, such that the secondary flow in the blades can be effectively inhibited, the jet flow wake strength of the blade outlet can be weakened, the influence of the limited blade number can be effectively weakened while the excretion coefficients at the outlet and the inlet of the gas suction zone and the gas discharge zone are not reduced, the blade wheel efficiency is increased, and the suction performance of the liquid ring vacuum pump and the compressing performance of the liquid ring vacuum pump adopted as the compressor can be improved.
