Abstract

The invention relates to an improved Roots water ring vacuum set. The improved Roots water ring vacuum set comprises a Roots pump body, a pair of rotors and a shaft, wherein the rotors and the shaft are arranged in the Roots pump body, and the rotors are engaged with each other. The improved Roots water ring vacuum set is characterized in that: an air inlet is arranged at the top of the Roots pump body; an air outlet is arranged at the bottom of the Roots pump body; the Roots pump body is connected with a hydraulic pump by a pipeline; a check valve is arranged in the pipeline; a control device is arranged between the pipeline and the Roots pump body; a rotary shaft, an impeller and a liquid ring are arranged in the hydraulic pump; the impeller is arranged outside the rotary shaft; the liquid ring is arranged outside the impeller; and an exhaust outlet is arranged at the top of a liquid ring pump. The improved Roots water ring vacuum set has the advantages of high efficiency, energy conservation, compact structure, high vacuum degree, large discharge capacity and stable performance, is adaptive to discharging a large amount of condensable vapor, improves the reliability of the pump, and prolongs the service life of the pump.
