Our simple refining uses a water ring vacuum pump, which has a low failure rate, but cannot lack water. Water ring pumps were originally used as self-priming water pumps. It is composed of impeller, pump body, suction and exhaust disc, water ring formed by water on the inner wall of the pump body, suction port, exhaust port, auxiliary exhaust valve, etc.

In many processes of industrial production, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum moisture resurgence and vacuum degassing, etc., water ring pumps are widely used. Due to the rapid development of vacuum application technology, water ring pumps have been paid attention to in obtaining rough vacuum. Because the gas compression in the water ring pump is isothermal, it can pump out flammable and explosive gases, and also can pump out dusty and water-containing gases. Therefore, the application of water ring pumps is increasing day by day.

A proper amount of water is installed in the pump body as the working fluid. When the impeller rotates clockwise in the figure, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring with approximately equal thickness that depends on the shape of the pump chamber. The inner surface of the lower part of the water ring is just tangent to the hub of the impeller, and the upper inner surface of the water ring is just in contact with the top of the blade (in fact, the blade has a certain insertion depth in the water ring). 

At this time, a crescent-shaped space is formed between the impeller hub and the water ring, and this space is divided into several small cavities equal to the number of blades by the impeller. If the lower part of the impeller is 0° as the starting point, the volume of the small cavity changes from small to large when the impeller rotates 180° before, and it communicates with the suction port on the end face. At this time, the gas is inhaled. When the suction ends, the small cavity Then it is isolated from the suction port; when the impeller continues to rotate, the small cavity changes from large to small, so that the gas is compressed; when the small cavity communicates with the exhaust port, the gas is discharged out of the pump.

To sum up, the water ring pump realizes suction, compression and exhaust by changing the volume of the pump chamber, so it belongs to the variable capacity vacuum pump.

The impeller is installed eccentrically in the pump body. When the impeller rotates, the water entering the water ring pump body is thrown around by the impeller. Due to the centrifugal force, the water forms a closed water chamber of equal thickness similar to the pump cavity. ring. The upper inner surface of the water ring is just tangent to the hub of the impeller, and the lower inner surface of the water ring is just in contact with the top of the blade. 

At this time, a crescent-shaped space is formed between the hub of the impeller and the water ring, and this space is divided into several small cavities equal to the number of blades by the impeller. If the upper part of the impeller is 0° as the starting point, then when the impeller rotates 180° before, the volume of the small chamber gradually changes from small to large, and the pressure decreases continuously, and it communicates with the suction port on the suction and exhaust disk. The pressure in the space is lower than the pressure in the pumped container. 

According to the principle of gas pressure balance, the pumped gas is continuously pumped into the small chamber, and it is in the suction process at this time. When the suction is completed, it is isolated from the suction port. From the section Ⅱ-Ⅱ to Ⅲ-Ⅲ, the volume of the small cavity is gradually decreasing, and the pressure is increasing continuously. At this time, it is in the process of compression. When the air pressure is low, exhaust air from the auxiliary exhaust valve in advance. From section III-III to I-I, the volume of the small chamber connected to the exhaust port further decreases and the pressure increases further. 

When the pressure of the gas is higher than the exhaust pressure, the compressed gas is drawn from the exhaust port. Discharge, during the continuous operation of the pump, the process of suction, compression and exhaust is continuously carried out, so as to achieve the purpose of continuous pumping.
