Zvinenge zvipenyu zvese zvinoda ooxygenkurarama, kunyanyanokutivanhu.Vanhu vanoda oxygen kuti vararame,uyehushoma hweokisijeni mumhepo inodiwa pakufema kwevanhu i19.5 muzana.Iyo OSHA yakaronga iyo yakakwana huwandu hweokisijeni mumhepovanhuinomhanya pakati pe19.5 ne23.5 muzana.Asi chii'Ndiwo huwandu hweokisijeni shoma yevarwere vanoda aokisijeni yezvokurapajenareta?
Kuchena kweokisijeni yemumabhodhoro ndeye ≥ 99.5%, uye hapana huwandu hweokisijeni hwakatsanangurwa kune jenareta reokisijeni yekurapa.Asi yakakodzera tekinoroji zviyero zveokisijeni zvigadzirwa zvekugadzira zvinopihwa.Michina yekugadzira ma molecular sieve oxygen inogadzira okisijeni ne molecular sieve variable pressure adsorption process, uye oxygen concentration inofanira kuva 90% ~96% (VN).Kazhinji kutaura, hapana okisijeni yekurapa inogona kuiswa mukurapa kwekiriniki kunze kwekunge iyo oxygen yemukati yasvika 93%.
Varwere vanofema mweya kana vachishandisazvokurapa okisijeni jenareta, nokudaro kuderedza kuwanda kweokisijeni.Iyo oksijeni yemukati inofemerwa nemuviri wemunhu ichaderedzwawo kunyangwe iyo yekurapa okisijeni jenareta yakashandiswa nekuda kwechimiro chemuviri wemunhu.Iko kusungirirwa kweokisijeni kunofanirwa kusangana neiyo yakaderera mwero (93%) kuve nechokwadi chekuti varwere vanogona kufemereka yakaringana okisijeni.
Parizvino, majenareta eokisijeni ezvokurapa ane 93% okisijeni yemukati ane matekinoroji akakura.Chero bedzi chigadzirwa chacho chinogona kushandiswa zvakajairika mukushandiswa, chinogona kuve nechokwadi cheiyo okisijeni zvinodiwa zvevarwere nezvipatara.Asi imba kana yehutano yeokisijeni jenareta ichave yakadzikisa huwandu hweokisijeni nekuda kwemaitiro asina kusimba ekugadzirwa uye zviyero, uye haisi dhiri hombe kana jenareta yeokisijeni yekurapa ichingoshandiswa kumba nechinangwa chekuchengetedza hutano, pachinzvimbo chekukurumidzira.Sarudza jenareta weokisijeni ane nyanzvi kana kuenda kuchipatara nguva zhinji kunorapwa mweya weokisijeni kana murwere achida kurapwa kwakasimba kweokisijeni kurapa kushomeka kweokisijeni.
