Abstract

The invention discloses a self-cooling water ring vacuum pump utilizing temperature difference refrigeration, which comprises an impeller shaft, blades, a shell, an air inlet and an exhaust port. On the housing, the blades are installed on the impeller shaft, the top of the blades is in contact with the working fluid, and the internal low-pressure cooling device encapsulated with the liquid working fluid is coupled inside the blades. The ingenious coupling of the present invention makes the structure of the water ring pump highly integrated, completely getting rid of the heavy dependence of the working water of the water ring pump on the external circulating cooling system, realizing the rapid transfer of the heat of the working fluid, and maintaining the working water at a lower temperature, directly improving the The suction capacity of the water ring pump.

Description

technical field [0001] The invention belongs to the technical field of water ring vacuum pumps, in particular to a self-cooling water ring vacuum pump utilizing temperature difference refrigeration. Background technique [0002] Water ring vacuum pump (abbreviated as water ring pump) is a kind of chamber variable volume to realize suction, compression and exhaust process. It belongs to a variable capacity vacuum pump. The impeller is eccentrically installed inside the shell. When the impeller rotates clockwise, the working water is thrown around by the impeller. Due to the action of centrifugal force, the water forms a closed ring of equal thickness inside the shell. The expansion and contraction of the volume space between the impeller and the water ring realize vacuum suction and The exhaust process is widely used in coal mines (gas extraction), chemical, pharmaceutical, mining, papermaking and other industries. [0003] However, the biggest disadvantage of the water ring...
