Closed circulation vacuum system is consisted with liquid ring vacuum pump and compressor, liquid and gas separator tank, heat exchanger, instrument and valves, internal pipeline, and common base plate.
The pumped gas enters the liquid ring vacuum pump/compressor from the pump inlet, after compressed by the liquid ring vacuum pump/compressor, the gas will enter to enter the gas-liquid separator together some of the working liquid. Inside the gas-liquid separator, the gas and liquid are separated, and the gas is discharged from the pump outlet, and the working fluid go from the heat exchanger and enter the liquid ring vacuum pump/compressor for recycling.
