Water ring vacuum pump working principle
EVP vacuum pump manufacturers to introduce a water ring vacuum pump working principle is what?
Water ring vacuum pump (referred to as
Water ring pump began as a self-priming pump, and then gradually used in petroleum, chemical, machinery, mining, light industry, medicine and food
The pump body is provided with an appropriate amount of water as the working fluid. When the impeller rotates clockwise in the figure, water is thrown around by the impeller. Because of the effect of centrifugal force, water forms a closed ring of approximately equal thickness depending on the shape of the pump chamber. The lower part of the water ring is exactly tangent to the hub of the impeller, and the upper part of the inner part of the water ring is just touching the top of the blade (in practice, the blade has a certain penetration depth in the water ring). At the moment, a crescent space is formed between the hub of the impeller and the water ring. If the bottom of the impeller 0 ° as starting point, so in front of the rotating impeller 180 ° when small cavity volume changes from small to big, and on the face of inspiratory mouth, air is sucked into at the moment, when the suction at the end of the small cavity is isolated from the rest of inspiratory mouth; When the impeller continuously rotates, the small cavity changes from large to small, so that the gas is compressed. When the small cavity and vent connected, the gas will be discharged from the pump.
To sum up,
Vacuum pump for gas collection
