ã€China Aluminum Network】 1, water ring vacuum pump is a crude vacuum pump, pump body, impeller, suction and exhaust plate, water in the pump body wall composed of water ring, exhaust port, suction port, auxiliary exhaust valve Such as the composition of the ultimate pressure it can achieve, on the single-stage pump is 2.66 ~ 9.31kPa; on the double-stage pump is 0.133 ~ 0.665kPa. Water ring pump can also be used as a compactor, it belongs to the low-pressure compressor, which The pressure range is (1～2)X105Pa. The pressure of the gas is 2. 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 gas-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.
3, water ring pump in the petroleum, chemical, machinery, mining, light industry, paper, power, metallurgy, medicine and food and other industrial and municipal and agricultural sectors in many processes, such as vacuum filtration, vacuum feeding, vacuum degassing Vacuum evaporation, vacuum concentration and vacuum rejuvenation have been widely used.
