Working principle of water ring vacuum pump:

　　Water ring vacuum pump (referred to as water ring pump) is a kind of rough vacuum pump, the ultimate vacuum it can achieve is 2000-4000Pa, and the vacuum degree of the unit composed with vacuum pump can reach 1-600Pa. Water ring pump can also be used as a compressor, called water ring compressor, which is a low-pressure compressor, with a pressure range of 1-2×105Pa gauge pressure.

　　Water ring pump was initially used as a self-priming water pump, and then gradually used in many industrial sectors such as petroleum, chemical, machinery, mining, light industry and food. In many industrial production processes, such as vacuum filtration, vacuum water diversion, vacuum feeding, vacuum evaporation, vacuum concentration, vacuum conditioning and vacuum degassing, water ring pump is widely used. Due to the rapid development of vacuum application technology, water ring pump has been paid attention to in obtaining rough vacuum. Since the gas compression in the water ring pump is isothermal, it can extract flammable and explosive gases, and also can extract gases containing dust and water, therefore, the application of water ring pump is increasing day by day.

　　An appropriate amount of water is installed in the pump body as the working fluid. When the impeller rotates clockwise, the water is thrown around by the impeller. Due to the centrifugal force, the water forms a closed ring approximately equal in thickness determined by the shape of the pump cavity. The inner surface of the upper part of the water ring is just tangent to the impeller hub, and the inner surface of the lower part of the water ring just contacts the top of the blades (in fact, the blades have 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 by the impeller into several small chambers equal to the number of blades. If the upper part of the impeller 0° is taken as the starting point, when the impeller rotates the first 180°, the volume of the small chamber changes from small to large, and it is connected with the suction port on the end face. At this time, gas is sucked in. When the suction ends, the small chamber is isolated from the suction port; when the impeller continues to rotate, the small chamber changes from large to small, so that the gas is compressed; when the small chamber is connected with the exhaust port, the gas is discharged out of the pump.
