water -haul vacuum pumps
Vacuum pumps are designed for absorption and pumping of dry gas with a temperature of up to 150ºС and saturated with pairs of gases, which differ in that their temperature does not exceed 100ºC, with the possibility of using working fluids with a viscosity of up to 60 mm²/s and a density of 800-1200 kg/m³ Water at the output of the pump should not exceed 80ºC.
operation of pumps: The working fluid should be continuously supplied to the pump during its operation, to remove heat released during compression and restoration of the liquid ring, since part of the liquid is thrown out with gas. The working fluid can be separated from gas in the output separator, and if necessary, returned again to the system. As a rule, water is used as a working fluid.
