Water vapor tolerance / water vapor capacity

Water vapor tolerance / water vapor capacity

Without gas ballast, a vacuum pump having an outlet temperature of less than 100°C would not be capable of displacing even small amounts of pure water vapor. If water vapor is nevertheless pumped without gas ballast, the condensate will dissolve in the pump oil. As a result, the base pressure will rise and the condensate could cause corrosion .

The gas ballast allows for efficient use on smaller systems. Cons It is a little heavy, but the shoulder strap helps to offset its weight. I have been in the HVAC service business since 1991, and this is my fifth vacuum pump. It is certainly one of the sturdiest that I have owned. It will stand up well to use on the job.

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.

Gas Ballast • By opening the Gas ballast valve on the rotary pump: 1. A small amount of air flows into the compression portion of the pump cycle. 2. This additional air mixes with the gas/vapor being compressed. 3. The gas/vapor mixture is now greatly diluted. There is more % of dry gas than % of vapors. 4. There is now less tendency of .

A wet pump uses low vapor pressure oil in the pumping mechanism. A diffusion pump, for example, uses oil vapor flow as the pumping mechanism while a rotary vane pump uses oil to lubricate and seal sliding joints between vanes and casing. So, in any wet pump, oil liquid and vapor coexist in the pumps vacuum volume. A dry pump has no gas sealing .
