Reasons for adding water to the water ring vacuum pump
The water ring vacuum pump body is equipped with an appropriate amount of water as the working fluid. When the water ring vacuum pump impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed loop of approximately equal thickness depending on the shape of the pump chamber. The water ring below the inner surface cuts the center of the impeller, except that the water ring on the inner surface of the upper part only contacts the tip of the blade (in fact, there is a certain depth of insertion in the water ring of the blade). At this time, a crescent-shaped space is formed between the water ring vacuum pump impeller hub and the water ring, and the space is divided into several small cavities equal to the number of impeller blades.
If the bottom impeller 0° is used as the starting point, then the water ring vacuum pump impeller rotates 180° before the small cavity volume changes from small to large, the nozzle is on the face, inhaling the gas, when the inhaled small cavity is independent of the other suction ports; when the impeller When the rotation continues, the small cavity becomes larger and smaller, so that the gas of the water ring vacuum pump is compressed; when the cavity is connected with the exhaust port, the gas is discharged from the pump.
