utekhi wesixa lokuseparakha lemfanele yasehlukwayo
Umvume weVPSA (Vacuum Pressure Swing Adsorption) wesiQephu somqondo wesigaba sithiwa ngokushesha kuhle kwiqhophiso lokusebenzisa amagase, uhlalekile ukufinyelela imininingwane yokusebenza okukhulu yokuhlala kweoxygen ne-nitrogen esikudleni sesikhatsi. Lomsebenzi omncane wahlukile ngaphandle kokuphucula kwezinye izindlela ezisebenzayo, uhlalekile ukusebenzisa i-cycles emasendaweni apho kukhona umoya wokusukela nge-compression, phakathi kwabo kumoya wokusukela wabuyiswe ngamagase apha apho angenziwe amagase angalokho. Ukusetyenziswa kuhlala kusuke kusuka komoya wesikhatsi sokubuya ku-vacuum conditions, uhlalekile ukwenza ukubuyiselwa kwe-adsorbent material nokuhlala kakhulu. Amasistemu ka-VPSA akhethiwe ngokulandelayo kunye nokusebenzela okuningi lomoya, zingene zonke izinsuku zihluke 25 kunye ne-30 percent lesinye sezinsuku ze-pressure swing adsorption ezifanekayo. Lezi zintsha ziqhophisa oxygen enge-90 kunye ne-95 percent, uzoba abahambisi basebenzela kwindawo ezininzi zezindawo ezindala. Umsebenzi wakhe womkhomboni wahlukile ukuba kungavumelekanga, ungene ngemibuzo yezinsuku ezincane kwezilimi ezincane kunye nemibuzo yezinsuku ezinkulu, uvumelekanga ukuthola indlela yokugcina kanye nokuthola amagcinelo amaningi amahle.
