water ring vacuum pump working

Water ring vacuum pump is a kind of product used in a series of process production activities after it was used as a suction pump. This also proves that its working principle also has a certain effect on other industries. Moreover, it is widely welcomed because of its uniform suction and stable and reliable operation. So what is its specific working principle? Let's have a look!
Since the gas to be transported in the water ring vacuum pump is isothermal after being compressed, it can be used to pump out inflammable, explosive, dusty and water containing gases. To work, as long as an appropriate amount of water is filled into the pump body as the working fluid, the water will be thrown around by the impeller when the impeller rotates clockwise in the direction indicated in the figure. Under the action of centrifugal force, the water can form a closed ring of approximately equal thickness, which is determined by the shape of the pump cavity. It is precisely because the upper inner surface of the water ring is tangent to the impeller hub and the lower inner surface is just in contact with the top of the blade.
At this time, the impeller hub and the water ring form a certain space, and the liquid in this space can be divided into several small cavities. When the upper part of the impeller is 0 ° as the starting point, the volume of the small cavity increases from small to large and is connected with the suction port on the end face when the impeller is 180 ° before rotation. If the gas is inhaled at this time, the small cavity is isolated from the suction port when the suction ends; When the impeller continues to rotate, the small cavity becomes smaller from larger so that the gas is compressed and the gas is discharged when the small cavity is connected with the exhaust port.
It can be seen from the above that the working principle of the water ring vacuum pump is to achieve suction, compression and exhaust by changing the volume of the pump chamber, and the configuration used in this principle can be more flexible and the range of use will be wider.
