Ijeneretha ye-oxygen yezokwelapha enobuchwepheshe be-pressure swing adsorption (PSA) njengesisekelo, ukukhipha umoya-mpilo emoyeni wemishini emisha, ukusetshenziswa kwe-adsorption ye-molecular sieve ngokomzimba kanye nenqubo ye-desorption ku-molecular sieve oxygen generator ekulayisheni, lapho ukucindezela emoyeni. kungaba i-nitrogen adsorption, i-oxygen esele engamuncwanga iyaqoqwa, ibe okungukuthi ngemva kokwelashwa kokuhlanzeka kokuhlanzeka okuphezulu komoya-mpilo.Inqubo ethile yokusebenza iwukuthi umoya ocindezelweyo uhlanzwa ngesomisi sokuhlanza umoya bese ungena embhoshongweni we-adsorption ngokusebenzisa i-valve yokushintsha.Embhoshongweni we-adsorption, i-nitrogen idsorbed ngesisefo samangqamuzana, umoya-mpilo unqwabelana phezulu kombhoshongo we-adsorption ethangini lokugcina umoya-mpilo, bese kuthi ngokususa iphunga, isihlungi sokukhipha uthuli kanye nesihlungi sokuhlunga inzalo kunikezwa umoya-mpilo wezokwelapha ofanelekayo.Izingxenye eziyinhloko yilezi: ithangi lomoya, i-compressor yomoya, umshini wokomisa obandayo, umgcini we-oxygen, ithangi le-oxygen nokunye.
