Pamberi pemakore ekuma1930, Germany neFrance chete ndivo vaigona kugadzira majenareta eokisijeni.Panguva iyoyo, majenareta eokisijeni (variable pressure adsorption okisijeni jenareta) aingokwanisa kuzadzisa zvinodiwa zvewelding nekucheka okisijeni nenitrogen kugadzira michina inodiwa kuindasitiri yemakemikari.Kugadzirwa kwemajenareta eokisijeni kwainyanya kudiki uye pakati nepakati, iine hurefu hwe2m3/h kusvika 600m3/h uye dzinenge mazana maviri marudzi.Theokisijeni jenaretanzira inoshandiswa ndeyepamusoro-kumanikidza uye yepakati-kumanikidza maitiro.
Kubva muna 1930 kusvika muna 1950, kunze kweGermany neFrance, dzimwe nyika dzakadai seSoviet Union, Japan, United States neUnited Kingdom dzakatangawo kugadzira magwenya eokisijeni.Munguva iyi, nekuvandudzwa kwekugadzirwa, nzvimbo yekushandiswa kwemajenareta eokisijeni (variable pressure adsorption oxygen generator) yakawedzerwa uye kugadzirwa kwemajini makuru eokisijeni kwakasimudzirwa.Sezvo magetsi nesimbi zvinhu zvaidiwa kugadzira 1 m3 yeokisijeni mumajenareta makuru eokisijeni aive akakwirira kudarika emagetsi madiki uye epakati-kati, majenareta makuru eokisijeni akawedzera zvakanyanya kubva ku1930 kusvika ku1950, zvakadai se5000 m3 / h mukati. West Germany, 3600 m3/h muUSSR uye 3000 m3/h muJapan.maitiro akashandiswa panguva iyoyo, kunze kwekumanikidzwa kwepamusoro nepakati, akatanga kushandisa maitiro epamusoro uye akaderera.Muna 1932, Germany yakashandisa majenareta eokisijeni kekutanga mumaindasitiri emetallurgical uye ammonia.
Mushure me1950, kuwedzera kune majenareta eokisijeni (variable pressure adsorption oxygen generator) akabudiswa munyika dziri pamusoro, kune China, Czech Republic, East Germany, Hungary, Italy, etc. )
Nekuda kwekuvandudzwa kweindasitiri yesimbi, nitrogen fertilizer indasitiri uye rocket tekinoroji, kushandiswa kweokisijeni nenitrogen kwakawedzera nekukurumidza, izvo zvakakurudzira kukura kwakakura kwemajenareta eokisijeni.Kubva 1957, 10,000m3/h majenareta eokisijeni akaunzwa imwe mushure meimwe.kubva muna 1967, maererano nehuwandu husina kukwana, kune 87 makuru majenereta eokisijeni pamusoro pe20,000 m3 / h, chikwata chikuru chiri 50,000 m3 / h, uye chikwata chikuru chiri pasi pekuvandudzwa.
Mumakore makumi maviri apfuura, rudzi rwechigadzirwa rwakawedzera nokukurumidza uye zvishoma nezvishoma rakagadzira mutsara.Semuenzaniso, West Germany Linde hombe okisijeni jenareta ine 1000 ~ 40000m3 / h zvakajairika zvigadzirwa;Japan kobelco ine OF dzakatevedzana;Japan Hitachi inogadzira ese TO modhi;Japan Oxygen ine NR mhando;Britain ine 50 ~ 1500 matani / zuva akatevedzana zvigadzirwa.Panguva imwecheteyo, majenareta makuru eokisijeni anoshandisa iyo yakazara yakaderera kudzvinyirira maitiro.
Muchidimbu, kugadzirwa kweokisijeni jenareta (variable pressure adsorption oxygen generator) inzira isina kukwana, uye midziyo yakagadzirwa kubva kudiki uye yepakati-saizi kusvika kuhombe.Maitiro acho akakura kubva pakumanikidzwa kwepamusoro (200 atmospheres), kumanikidzwa kwepakati (50 atmospheres) uye yakakwirira uye yakaderera kumanikidzika kusvika kune yakazara yakaderera (6 atmospheres), nokudaro kuderedza kushandiswa kwesimba reyuniti uye kushandiswa kwesimbi kwejenareta uye kuwedzera kushanda. cycle.
