Abstract

The invention relates to the technical field of vacuum pumps, and discloses a cooling mechanism of a water ring vacuum pump. The cooling mechanism comprises a shell; an air suction port is arranged above the middle part of one side of the shell; an exhaust port is arranged below the middle part of one side of the shell; a medium is stored on the bottom surface of an inner cavity of the shell; and a driving wheel is movably connected below the middle part of the inner cavity of the shell. Through the arrangement of an internal cooling mechanism, when a beating trash removal mechanism works normally and a piston rod is rapidly thrown out under the action of centrifugal force, air to be exhausted is sucked into a refrigeration cavity through a vent hole, and the air suction amount in the refrigeration cavity is small under the effect that the opening range is small when the vent hole sucks air; and under the effect that the outward moving amplitude of the piston rod is large, air in the refrigeration cavity expands under the effect of negative pressure and absorbs a small amount of heat, so that when the water ring vacuum pump works normally, the refrigeration cavity continuously absorbs a small amount of heat, and the inner cavity of the water ring vacuum pump is continuously subjected to heat absorption and cooling.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a cooling mechanism of a water ring vacuum pump. Background technique [0002] The water ring vacuum pump, referred to as the water ring pump for short, is a kind of chamber variable volume to realize the suction, compression and exhaust process, which belongs to a variable capacity vacuum pump. When the impeller rotates clockwise, the working water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring of equal thickness inside the shell. At this time, a crescent-shaped space is formed between the impeller and the water ring. This space is divided into several "small cavities" with the same number of blades by the impeller. If the upper part of the impeller is 0° as the starting point, the volume of the "small cavity" will change from small to large when the impeller rotates 180° before the impeller is formed. The vacuum sucks...
