Phambi koo-1930, ngokusisiseko yiJamani neFransi kuphela ezazinokuvelisa iijenereyitha zeoksijini.Ngelo xesha, iijeneretha ze-oksijini (i-variable pressure adsorption oxygen generators) zinokuhlangabezana kuphela neemfuno ze-welding kunye nokusika i-oksijini kunye nezixhobo zokuvelisa i-nitrogen ezifunekayo kwishishini lemichiza.Ukuveliswa kweejeneretha ze-oksijini kwakuncinci kunye nobukhulu obuphakathi, kunye nomthamo we-2m3 / h ukuya kwi-600m3 / h kunye neentlobo ze-200.Iijenereyitha yeoksijiniInkqubo esetyenziswayo yinkqubo yoxinzelelo oluphezulu kunye noxinzelelo oluphakathi.
Ukususela ngowe-1930 ukusa kowe-1950, ukongezelela kwiJamani neFransi, amanye amazwe anjengeSoviet Union, iJapan, iUnited States neUnited Kingdom nawo aqalisa ukuvelisa oomatshini bokuvelisa ioksijini.Ngeli xesha, kunye nophuhliso lwemveliso, intsimi yesicelo se-oxygen generators (i-variable pressure adsorption oxygen generators) yandiswa kwaye ukuphuhliswa kweejeneretha ezinkulu ze-oksijeni zakhuthazwa.Njengoko umbane kunye nezixhobo zetsimbi ezifunekayo ukuvelisa i-1 m3 ye-oksijeni kwiijeneretha ezinkulu ze-oksijeni zaziphezulu kunezo zincinci kunye ne-oxygen generator generators, iindidi ze-oxygen generators ezinkulu zanda ngakumbi ukusuka kwi-1930 ukuya kwi-1950, njenge-5000 m3 / h. I-West Germany, i-3600 m3 / h kwi-USSR kunye ne-3000 m3 / h eJapan.iinkqubo ezisetyenzisiweyo ngelo xesha, ngaphezu koxinzelelo oluphezulu kunye noluphakathi, lwaqala ukusebenzisa iinkqubo zoxinzelelo oluphezulu kunye noluphantsi.Ngo-1932, iJamani yasebenzisa iijenereyitha zeoksijini okokuqala ngqa kwimizi-mveliso ye-metallurgical kunye ne-ammonia.
Emva kwe-1950, ukongeza kwiijenereyitha ze-oxygen (i-variable pressure adsorption oxygen generators) eveliswa kula mazwe angasentla, kukho i-China, i-Czech Republic, i-East Germany, i-Hungary, i-Italiya, njl. ).
Ngenxa yophuhliso loshishino lwentsimbi, imboni yesichumiso se-nitrogen kunye neteknoloji ye-rocket, ukusetyenziswa kwe-oksijini kunye ne-nitrogen kuye kwanda ngokukhawuleza, okuye kwakhuthaza ukuphuhliswa okukhulu kweejeneretha ze-oksijini.Ukususela ngo-1957, i-10,000m3 / h iijenereyitha ze-oksijini ziye zaziswa enye emva kwenye.ukususela ngo-1967, ngokwezibalo ezingaphelelanga, kukho i-87 enkulu yeejeneretha ze-oksijeni ngaphezu kwe-20,000 m3 / h, iyunithi enkulu yi-50,000 m3 / h, kwaye iyunithi enkulu iphantsi kophuhliso.
Kwiminyaka engama-20 edlulileyo, uluhlu lwemveliso luye lwanda ngokukhawuleza kwaye ngokuthe ngcembe lwakha uluhlu.Ngokomzekelo, i-West Germany i-oxygen generator enkulu ye-Linde ine-1000 ~ 40000m3 / h iimveliso eziqhelekileyo;Japan kobelco has OF series;IJapan iHitachi yenza zonke iimodeli ze-TO;I-Oxygen yaseJapan inohlobo lwe-NR;IBritane ine-50 ~ 1500 yeetoni / iimveliso zothotho lweentsuku.Ngelo xesha, iijeneretha ezinkulu ze-oksijini zisebenzisa inkqubo epheleleyo yoxinzelelo oluphantsi.
Ngamafutshane, ukuphuhliswa kwe-oxygen generator (i-variable pressure adsorption oxygen generator) yinkqubo engafezekanga, kwaye izixhobo ziye zaphuhliswa ukusuka kumncinci kunye nobukhulu obuphakathi ukuya kubukhulu.Inkqubo iphuhliswe ukusuka kuxinzelelo oluphezulu (i-200 atmospheres), uxinzelelo oluphakathi (i-50 atmospheres) kunye noxinzelelo oluphezulu kunye oluphantsi ukuya kuxinzelelo oluphantsi olupheleleyo (i-6 atmospheres), ngaloo ndlela inciphisa ukusetyenziswa kwamandla eyunithi kunye nokusetyenziswa kwentsimbi ye-oxygen generator kunye nokwandisa ukusebenza. umjikelo.
