umphumo wombuzo wokusebenza kweVPSA yebhokisi
Umkhuhlane wokuthula amagama esincane kweoxygen (VPSA - Vacuum Pressure Swing Adsorption) ufumanisa umthombo omphambili wesibhedlela lokusebenzela ukwakhiwa kokuthula amaxabiso ekuseni lokufika okanye lokulandelayo. Isistimu esisophakeme lesi sebenza ngokusebenzisa imibuzi yamolekule ezikhulu ezifihlileyo ezinikezela ukubuyiselwa inyoni kumoya osaphathelene, ukuze i-oxygen lisebenze. Umthetho wokuqala ulandelayo ngezilimi ezimbini: ukuphazamiswa nokuhlola ngemvume. Ngokuphazamiswa, umoya omphahla waphuma phakathi komphilo wezi-molecular sieve, apho amagama angonyoni azigcwalisisa kunye ne-oxygen alandelayo. Ukuvamile ngemuva kuhlola ngemvume, ukuvamile kuhlanganisa izinhlobo zezimolecular sieve ngokubuyiselwa amagama angonyoni. Lomkhuhlane wasebenza ngokulandelana ngokuba kuhlanganisa ukuthula kwe-oxygen, ngokushesha eliphambili lokungabangako. Ukukhuluma nokuhlola kuhlanganiswa ngokusebenzela amasistimu akhona asebenza nokujikijisa amaparamitha, kakhulu lokuphazamiswa, amasheshi amaphambili, kunye nokuthi lemfawuluko. Umthetho lwakhe lufuna umoya olunyeleyo ngokuphambili kwezi zinto ezilandelayo lokusebenzela ukuthula kwe-oxygen, lokungenza kuhlanganisa ukuthula kwe-oxygen, lokungenza kuhlanganisa ukuthula kwe-oxygen. Imikhuhlane ye-VPSA yakhiwe kunye nokugcina ukuthi bavalele ngokuphambili kwezi zinto ezinomsindo ezilandelayo lokusebenzela ukuthula kwe-oxygen, kusukela izindlu ezincane zezi-medicene kunye nemikhuhlane emakhulu yokuthula kwe-oxygen.
