The most common of them is pumping the cryogenic pump, by one mechanical pump. So that, when the main valve of pump (valve, between pump and vacuum chamber) is closed, heating the cryogenic pumps, and then, one carrier gas (usually nitrogen) is inserted into a cryogenic pump and on the other hand is pumped by rotary pump and thus, being outside all gases and vapors through the pump
been condensed onto a surface cooled to liquid nitrogen temperature. Cryo-sorption Pumps Cryo-sorption pumps provide a safe, quiet, clean and reasonably inexpensive method for evacuation of a vacuum vessel to a pressure of 10-3 Torr. Most commercial cryo sorption pumps resemble the diagram in figure 11.2. Liquid nitrogen is used to cool the

Abstract:Cryogenic pumps are attractive for electric propulsion test facilities due to their pumping speed on propellant gases of interest. Cryopumps utilize a liquid nitrogen-cooled radiation shroud to allow the internal cryosail to reach its operating temperature. Traditional cryopump installations use an open-loop LN 2 feed system which vents evaporated gas to the atmosphere..

THE DELTA N PUMPS. Thanks to its numerous advantages such as reliability and low maintenance costs, this product has become the most standard pump for automatic filling stations. Available flow rates:1 to 500 L/min (triplex version) Pressure up to 1'000 bar.
Vacuum Requirements for Cryogenic Vessels Normandale The vacuum levels necessary will usually require both a roughing pump and a high-vacuum pump. Even though an oil-sealed mechanical pump can easily produce a vacuum of 10 millitorr, which is often considered adequate for some liquid nitrogen dewars, the pumping speed of mechanical pumps drop to near zero at these pressures.
