isibhokisi somoya esikhathalelweyo kwiseva yomoya
I-Vacuum Pressure Swing Adsorption (VPSA) uqaphela lwezibophelelo le-oxijeni kukhombisa umthetho omusho wokulandelana nge-oxijeni, uhluke amandla nokugcina ukusebenza kakhulu lokuhlala okuphakamisileyo. Isistimu esisodwa sokuqalise kuhlukileyo ngokusetshenziswa kwezicatshulwa ezikhoyo zomdlalo osebenza ukubheka i-nitrogen ethi kwesiphumo esihlangene ngesikhatsi esemva kokuthi i-oxijeni zingabheke. Umsebenzi ubonisa amaqanda abili: uphawula nokuvumelela ngokusebenzisa isikhatsi, okufuneka kube kusenzo esiqendu sesikhathi sokuhlala kakhulu. Ngokusebenza, isiphumo esihlangene siyongezelekile kanye nezincwadi ezinathathisiwe eziphumayo imdlalo we-sieve, apho amadaba anganithathisiwe kunye noxijeni angabheke. Isistimu sethuzele isikhatsi sokuvumelela ukwenza ukuba amandla asebenze ukudibanisa, ukulayishwa kakhulu lokusebenza. Izi VPSA ezintsha zikwazi ukuba ziziphiwe izilungu ze-oxijeni ekuphakamisweni kwe-95%, ukuba zikhona kuzama kakhulu lokuncane lokusebenzela kwindawo eziningi zezindawo, zezidingo nokuzimela. Lwendawo lwahlukileyo luhlobene nesiqhathaniso esisodwa sezinhlobo ezifanele yokubheka nokugcina izimpawu zokusebenza ngokurekhweba, ukusigcina ukuba kuhloyo nokuba kuhloniphe yinkomo yokusebenza yesibhedlela. Lwendawo elenza ngothando lokusebenzela kakhulu lokunikeza amandla nokuthola amandla kakhulu lokusebenzela kakhulu.
