Water ring pump related knowledge

The water ring pump is a crude vacuum pump, which is composed of a pump body, an impeller, a suction and exhaust plate, a water ring formed by water in the inner wall of the pump, an exhaust port, an intake port, and an auxiliary exhaust valve. It can achieve the ultimate pressure. The single-stage pump is 2.66 to 9.31 kPa; the dual-stage pump is 0.133 to 0.665 kPa. The water ring pump can also be used as a compactor, which belongs to a low pressure compressor and its pressure range is (1~2)X105Pa gauge pressure.

The gas enters the water ring pump through the valve through the valve, and then is discharged into the gas-water separator through the gas-guiding elbow and discharged through the gas-water separator exhaust pipe. When used as a compactor, after the gas-water mixture discharged by the auger separates in the gas-water separator, the gas is sent through the valve to the system requiring the compressed gas, while the water is left in the gas-water separator, so that the gas water When the water level is higher than the requested water level, the overflow switch opens and the water overflows from the overflow pipe. When the water level is lower than the requested water level, the overflow switch is turned off, and the water-separator is turned off. The water level rises and reaches the requested water level. The working water in the water ring pump is supplied by the gas-water separator. The amount of water supply is adjusted by the valve on the water supply pipe.

Water ring pumps are used in many processes such as petroleum, chemical, machinery, mining, light industry, papermaking, power, metallurgy, medicine, food, and other industrial and municipal and agricultural sectors such as vacuum filtration, vacuum feeding, vacuum degassing, vacuum Evaporation, vacuum concentration and vacuum rejuvenation have been widely used.
