ukushaya kwezinhlobo zokuphucula ngokwesikhephe esiqedwa ngesiphumo lesibhokisi
Ukuphinda-kuphinda kwezinye zokuthiwa (PSA) ngephakathi kweoxygen kusetshenziswa okungakhothani lokusebenza ukusukumisa oxygen kwehlathi lesikhatsi. Lolu hlobo lokusebenza lasebenzisa amaxhobo omncane wamashova angasetyenziswa esezisetyenziswa ukusuka ngokubanjwa imibhalo yezilondolozi ezizityenziswa ngokubanjwa i-nitrogen ngalokhu akusukeleleyo oxygen ukuze uphume. Isistimu sikusebenza ngokushesha lwesikhatsi, apho isikhatsi esiphindvwe sifunyelwe ngaphakathi komkhosi obonakaleyo olufakwe neziphi zezilondolozi ezisetyenziswa. Ngokushesha lwemikhatsi, amagama lwe-nitrogen asikhangathisiwe ngaphakathi komshova, apho amagama lwe-oxygen ayisebenzi ngokulandelana. Ngalokhu alandelayo lokusebenza, amagama lwe-nitrogen asikhangathisiwe futhi asihambiswe kudla kwesisistimu. Lokuncane lwesikhatsi lwenze ukusukumisa umoya omphini we-oxygen, usuku lokungabangako 95%. Izindlela ezintsha ze-PSA zisetshenziswa amasistimu amancane apha ukuzipha indlela yokuphinda kuphinda kwezinye zokuthiwa, ukusure ukuthiwa kweoxygen ngokuzuzwa futhi ukusuka elingeneleyo nokuhlawula ukusetyenziswa. Lolu hlobo lokusebenza luyisebenzela ngokupheleleyo ngazo zindawo ezininzi, phakathi kwezindawo ezinikezeli, ngokuhlola izindawo ezinikezeli, ukusukumisa amadoda, nokusukumisa iglass. Ukusetha kwezinye zayo ezinhloko ziyahlukanisa ukuba kusetshenziswa ngendawo, ukuba kunyenyezi kakhulu nakusetshenziswa ngendawo encinci. Umsebenzi owunene uhlaziyiwe ngokwesikhatsi, ukuthi kudingekileyo futhi ukuthiwa kweoxygen ngokuzuzwa ngaphandle kokugcina nokuthuthukiswa kwezikhathi.
