umkhondo wokuhlanganisa oksheni lweVPSA
Uhlelo lwe-VPSA (Vacuum Pressure Swing Adsorption) lwe-oxygen concentrator luyisisombululo esiphambili sokukhiqiza i-oxygen yezimboni nakwezokwelapha. Lolu hlelo oluthuthukile lusebenzisa izinto ezikhethekile zokuhlunga izinhlayiyana ukuze kuhlukaniswe umoya-mpilo nomoya ozungezile ngenqubo elawulwa kahle yokucindezela. Isebenza ngomgomo wokuncishiswa kokukhetha, uhlelo lwe-VPSA luthatha ama-molecule e-nitrogen kuyilapho luvumela umoya-mpilo ukuba udlule, okuholela ekukhiqizeni umoya-mpilo ohlanzekile. Uhlelo luqukethe izitsha ezimbili eziyinhloko zokumunca ezisebenza ngokuzivumelanisa, enye yenza inqubo yokumunca kanti enye ivuselelwa. Lo mjikelezo oqhubekayo uqinisekisa ukuthi umoya-mpilo awuphazamiseki. Izinhlelo zanamuhla ze-VPSA ngokuvamile zifinyelela emazingeni okuhlanzeka komoya-mpilo afinyelela kuma-95%, ngamakhono okukhiqiza asukela ezikhungweni ezincane kuya kuma-unit amakhulu ezimboni akwazi ukukhiqiza izinkulungwane eziningana zamamitha ayisikubhu ngehora. Lolu hlelo lunemishini yokulawula eyinkimbinkimbi, kuhlanganise nezinzwa zengcindezi, amamitha okugeleza, nezinhlelo zama-valve ezizenzakalelayo, okuqinisekisa ukusebenza kahle nokusebenza kahle. Ukusetshenziswa kwamandla kuphansi kakhulu uma kuqhathaniswa nezindlela zokuhlukanisa eziqandisiwe, okwenza kube inketho esebenzayo kwezomnotho ekusetshenzisweni okuhlukahlukene. Ukuhlukahluka kwezinhlelo ze-VPSA kufinyelela ezimbonini eziningi, kuhlanganise nezikhungo zezempilo, ukucutshungulwa kwensimbi, ukukhiqizwa kwengilazi nezitshalo zokuhlanza amanzi angcolile.
