Many translated example sentences containing "gas ballast valve" – German-English dictionary and search engine for German translations. Hi Guys, I`ve noticed a few posts asking what a gas ballast valve on a vacuum pump is for.

The gas ballast valve in most pumps ‘meter in’ a controlled amount of atmospheric gas into the compression cycle of the pump, thus ‘diluting’ the amount of vapour that is being compressed. Gas Ballast • By opening the Gas ballast valve on the rotary pump: 1. Refer to Section 7 for details about vibration isolators and other recommended accessories. Gas ballast should generally be run all the time that vapour ... exhaust valve of the pump opens. Properly using a gas ballast valve as found on a mechanical oil sealed vacuum pump has been considered by some to be an arcane art and practiced blindly much of the time.

This additional air mixes with the gas/vapor being compressed. Some gas ballast valves from specific manufacturers have three positions which are “closed”, “medium-flow” and “maximum-flow”. A0086. A small amount of air flows into the compression portion of the pump cycle. Please contact customer care for pricing.

Weight. The pumps are driven by a directly flanged motor.

GAS BALLAST VALVE; GAS BALLAST VALVE [ Enlarge ] Details. Depending on the size of the pump and the amount of oil in it, gas ballasting … If vapour is being pumped, the vacuum pump’s ultimate pressure will be limited, not by ultimate pressure performance of the pump itself, but by the vapour pressure of the material being processed. GAS BALLAST GASKET E1M175-27.

That oil can be separated in an oil mist filter and reused if clean. APGX-H-NW25 St/St+ Cal Cert.

There is more % of dry gas than % of vapors. Gas ballast prevents condensation of vapors inside the pump by diluting the pumped gas with the air being drawn in through the ballast valve. Quantity Add to Cart. If the atmosphere that you are removing from the refrigeration system is moisture laden, as that moisture enters the pump it is in vapor form, it is in a state of equilibrium with the air in the system. Actually, gas ballasting is a very simple operation and when properly applied can keep vacuum pumps in optimal conditions even when used in wet processes that can potentially contaminate the oil with condensation. 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. I was in the workshop the other day rebuilding a two stage Edwards vacuum pump and looking at the manual I found this information: "In a pump stored with the same oil for a long time condensed vapours may contaminate the oil bath and affect performance.
