49 results about "Sorption pump" patented technology

The sorption pump is a vacuum pump that creates a vacuum by adsorbing molecules on a very porous material like molecular sieve which is cooled by a cryogen, typically liquid nitrogen. The ultimate pressure is about 10⁻² mbar. With special techniques this can be lowered till 10⁻⁷ mbar. The main advantages are the absence of oil or other contaminants, low cost and vibration free operation because there are no moving parts. The main disadvantages are that it cannot operate continuously and cannot effectively pump hydrogen, helium and neon, all gases with lower condensation temperature than liquid nitrogen. The main application is as a roughing pump for a sputter-ion pump in ultra-high vacuum experiments, for example in surface physics.

Method of operating an adsorption refrigeration system

A method is provided of operating an adsorption refrigeration system. The system comprises a primary adsorption pump which is arranged in communication with a primary chamber containing coolant, a secondary adsorption pump and a high fluid impedance conduit which places the secondary adsorption pump and primary chamber into communication. The method comprises saturating the primary and secondary adsorption pumps with coolant whilst each pump is at its respective operational temperature. The pumps are then heated above their operational temperatures to desorb the coolant such that the coolant pressure in the primary chamber and the secondary adsorption pump substantially equalises through the conduit whilst the primary chamber is cooled. The secondary adsorption pump is then cooled causing coolant gas to be adsorbed and therefore a reduction in temperature and pressure of the coolant in the primary chamber is effected. The primary adsorption pump is then cooled to an operational temperature causing adsorption of the coolant and therefore a reduction in temperature and pressure of the coolant in the primary chamber.
