A water ring pump is a type of rough vacuum pump; it consists of a pump body, impellers, suction and discharge plates, a water ring formed by water on the inner wall of the pump, a discharge port, a suction port, and an auxiliary discharge valve. The ultimate pressure that such a pump can achieve is, for single-stage pumps, between 2.66 and 9.31 kPa； For two-stage pumps, the pressure range is 0.133–0.665 kPa. Water ring pumps can also be used as compressors; they belong to the category of low-pressure compressors, with a pressure range of (1–2)×105 Pa gauge pressure. 2. The gas enters the water ring pump through pipes and valves, then is routed via an air guide elbow to the gas-water separator, from where it is discharged through the exhaust pipe of the gas-water separator. When used as a compressor, the gas-water mixture discharged by the compressor is separated in a gas-water separator; the gas is then sent to the system that requires compressed air through valves, while the water remains in the gas-water separator. An automatic overflow switch is installed to maintain a constant water level in the separator. When the water level rises above the desired level, the overflow switch opens and water overflows through the overflow pipe. When the water level drops below the desired level, the overflow switch closes, allowing the water level in the separator to rise again until it reaches the desired level. The working water in the water ring pump is supplied by the gas-water separator, and the amount of water supplied is adjusted by the valve on the water supply pipe. 3. Water ring pumps are widely used in numerous processes across various industries such as petroleum, chemicals, machinery, mining, light industry, papermaking, power generation, metallurgy, pharmaceuticals, and food processing, as well as in municipal and agricultural applications. These processes include vacuum filtration, vacuum feeding, vacuum degassing, vacuum evaporation, vacuum concentration, and vacuum rehumidification.
