The use of gas ballast in rotary vane vacuum pumps- Vacuum .

The ballast valve can accelerate the extraction of steam without polluting the oil. If the rotary vacuum pump only pumping permanent gas, the gas does not liquefy due to the increase in pressure, so there is no deterioration of the pump oil. However, if the pump is used to vacuum dry or pumping humid air, the gas will have not only permanent gas but also Water vapor, if this portion of water .

Gas ballast

Gas ballast

4.1.6 Gas ballast. Means through which air or another non-condensing gas is admitted into a vacuum pump are referred to as gas ballast. If the pump is displacing vapor that would condense in the pump at the corresponding temperatures without gas ballast, the gas ballast enables the outlet valve to open before the vapor condenses, and the vapor is discharged together with the ballast gas.
