Roughing pump - Wikipedia

Roughing pump - Wikipedia

A roughing pump is any vacuum pump (typically mechanical) used to initially evacuate a vacuum system, as a first stage towards achieving high vacuum or ultra high vacuum.The term "roughing pump" derives from the vacuum range it works in, "rough vacuum", above 1x10 −3 torr (0.1 Pa).Pumps that operate in the high vacuum ranges typically don't operate, or only operate inefficiently, at .

Injector - Wikipedia

Injector - Wikipedia

An injector is a system of ducting and nozzles used to direct the flow of a high-pressure fluid in such a way that a lower pressure fluid is entrained in the jet and carried through a duct to a region of higher pressure. It is a fluid-dynamic pump with no moving parts, excepting a valve to control inlet flow. A steam injector is a typical application of the principle used to deliver cold water .

GAS BALLAST VALVE OPERATION - Industrial Vacuum Pumps .

GAS BALLAST VALVE OPERATION - Industrial Vacuum Pumps .

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. All high vacuum pumps have a maximum amount of water vapour tolerance i.e. the quantity of water that the pump can successfully pump without .

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

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 .

Vacuum pump gas ballast. What's it for and how important .

Jim Bergmann had a pretty thorough explanation about the function of the gas ballast. "The purpose of a gas ballast in a vacuum pump is to prevent water vapors from condensing during the discharge stroke of the vacuum pump. Water can only be removed from a system in vapor form.

Water vapor tolerance / water vapor capacity

Water vapor tolerance / water vapor capacity

The water vapor tolerance increases as the exhaust temperature of the pump rises and gas ballast flow q pV,Ballast increases. It decreases at higher ambient pressure. 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.

The pump has an oil distribution valve which prevents discharge of oil to the pump interior (suckback) after the pump stops. The pumping chambers are air-tight, so this arrangement prevents oil suckback unless the gas ballast valve is open. You can inspect the level and condition of oil in the oil box reservoir through the oil sight-glass.
