Oxygen rage: ka'idar aiki, aikace-aikace

By Cristiano Antonino On Aug 25, 2022

Muhimmancin mai rage iskar oxygen: samar da iskar oxygen ya zama dole a wasu ayyukan ceto na gaggawa (alal misali, waɗanda suka ji rauni a cikin wani hatsari), da kuma lokacin kulawa da marasa lafiya da marasa lafiya waɗanda ke fama da ƙarancin jikewa (kashi na oxyhemoglobin cikin jini)

Ya kamata a daidaita adadin iskar oxygen ta la'akari da shekaru, yanayin halin yanzu da bukatun jikin mai haƙuri.

Don wannan dalili, ana amfani da mai rage iskar oxygen, wanda aka tsara don daidaita kwararar iskar O2 da aka kawo daga silinda.

Mai rage iskar oxygen wata na'ura ce ta musamman wacce ke daidaita matsin iskar gas ta hanyar rage yawan matsa lamba mai shigowa zuwa ƙasa da matsa lamba mai sarrafawa.

Yana adana shi akai-akai akan saiti iri ɗaya ƙimar aiki, duk da sauye-sauyen matsa lamba.

Ta yaya mai rage iskar oxygen ke aiki?

Mafi kyawun mai sarrafa iskar oxygen da ake samarwa daga silinda ya ƙunshi abubuwa kamar:

rage bazara;
kulle bazara;
daidaita dunƙule;
roba membrane;
nono;
farantin matsa lamba;
bawul ɗin ci.

Bawul shi ne babban abin da ke cikin na'urar, saboda a koyaushe yana ƙarƙashin rinjayar matsi na mashigai da na iskar gas, wato runduna biyu masu gaba da juna.

Ka'idar aiki na mai rage iskar oxygen

Oxygen a cikin silinda yana ƙarƙashin matsin lamba sosai.

Zai zama mai haɗari sosai don allurar shi ga majiyyaci a cikin wannan nau'i, saboda haka ya zama dole don rage yawan iskar gas zuwa dabi'un halitta.

Mai sarrafa iskar oxygen shine na'urar da ke ba da damar isar da iskar oxygen a matsi mai dacewa, ba tare da la'akari da abubuwan waje ba.

Wannan shine mafita mai mahimmanci duka yayin ayyukan farfadowa na ayyukan gaggawa na gaggawa, da kuma lokacin kula da marasa lafiya waɗanda ke buƙatar isar da iskar oxygen a gida, a asibiti ko wasu ma'aikatan kiwon lafiya na musamman.

Tunda ana ba da kulawar jinya ta mutanen da ba lallai ba ne su sami ilimin likitanci, da kayan aiki Ya kamata su yi amfani da su zama mai sauƙi da fahimta kamar yadda zai yiwu a cikin aiki.

Wannan shine ainihin abin da mai rage iskar oxygen yake - an gina shi da kayan aiki masu ɗorewa kuma baya buƙatar ƙwarewa na musamman.

Mahimmanci, mai sarrafa matsi na iskar oxygen yana da alaƙa da aiki mara matsala.

Wannan yana rage haɗarin yanayin rikice-rikice kuma yana ba da damar iyakar ta'aziyya ga duka masu haƙuri da ke buƙatar maganin oxygen da masu kulawa.

Yadda za a kafa mai rage iskar oxygen: mataki-mataki

Kafin shigar da akwatin gear, duba zoben rufewa na abin da ya dace.
Bude bawul ɗin Silinda. Duba ma'aunin matsa lamba don ganin ko akwai isassun iskar gas a cikin silinda.
Tabbatar cewa an saita canjin kwararar iskar gas a saman silinda zuwa sifili.
Saka akwatin gear kai tsaye kai tsaye zuwa dannawa. Haɗa bututu zuwa mai daidaitawa.
Saita mai daidaitawa zuwa saiti mai gudana ta amfani da mitar kwarara.
Bari iskar oxygen ta shiga cikin mai ragewa ta hanyar buɗe bawul ɗin silinda sannu a hankali.

Me yasa akwatin gear ya daskare akan tankin oxygen?

Ana tattara condensate a cikin tankin oxygen.

Lokacin da iskar gas ya yi sanyi, ɗigon danshi yana daskarewa zuwa yanayin ƙananan ƙanƙara kuma yana iya toshe wurin.

Wannan yana faruwa ne kawai tare da saurin iskar oxygen.

Ana iya hana daskarewa akwatin gear ta amfani da akwatin gear mai ɗaki 2 ko silinda da yawa, ana canza su lokaci-lokaci. Duk da haka, duka biyu ba su da arha.

Sabili da haka, akwai wani zaɓi - don shigar da mai sarrafawa tare da jikin tagulla a kan silinda na oxygen, wanda ke da babban juriya ga daskarewa.

Yadda za a tsaftace (zuba) mai rage iskar oxygen?

Dole ne a yi amfani da mai rage matsa lamba ta hanyar da za a cire shigar da man shafawa da lalacewar injiniya (scratches, cracks).

Idan an sami burbushin mai da mai mai mai ko wasu abubuwa masu kitse, dole ne a wanke akwatin gear a cikin kowane sauran ƙarfi (kananzir jirgin sama, farin ruhu, barasa ethyl, turpentine, da sauransu).

Domin tsaftace kayan aikin zaren daga ƙura da datti, ana iya busa su kawai.

Menene bambanci tsakanin mai rage iskar oxygen da nitrogen, acetylene, carbon dioxide daya?

Masu sarrafa acetylene, nitrogen da carbon dioxide suna da tsari iri ɗaya da ƙa'idar aiki kamar masu rage iskar oxygen. A waje, sun bambanta kawai ta hanyar da aka haɗa su da bawul ɗin Silinda.

Misali, an haɗa mai rage acetylene zuwa silinda ta hanyar matse karfe da aka sanya a sama kuma an ƙara matsawa da maƙarƙashiya.

Shin zai yiwu a sanya mai rage iskar oxygen akan silinda carbon dioxide?

Kowane gas yana da halayen halayensa (ionization, zafin jiki, reactivity, da dai sauransu).

Don haka, ana ba da shawarar a bi ƙayyadaddun ƙayyadaddun masana'anta kuma a yi amfani da masu rahusa don silinda don manufar da aka nufa da ita.

Ma'auni na matsa lamba akan masu rage oxygen suna da matsakaicin matsa lamba na 25.0 MPa (250 yanayi) a shigarwa da 2.5 MPa (25) a fitarwa.

Matsakaicin an saita akan ma'aunin matsa lamba na masu rage carbon dioxide: 16.0 Mpa (160) a mashigai da 1.0 Mpa (10) a wurin fita.

Hakanan ana saita bawul ɗin aminci na oxygen da masu rage carbon dioxide don matsi daban-daban na iskar gas.

A ka'ida, an yarda da fasaha ta hanyar amfani da na'urar rage oxygen maimakon carbon dioxide, amma akasin haka, an haramta shi sosai don shigar da shi. Wannan ya faru ne saboda babban haɗari da haɗarin fashewar silinda.

Yadda za a zabi mai kula da matsa lamba oxygen?

Masu rage iskar oxygen suna samuwa a cikin zane-zane daban-daban kuma sun bambanta da kauri na ganuwar gidaje, don haka dole ne a yi la'akari da abubuwa da yawa lokacin siyan.

Wadannan su ne ka'idojin zabar na'urar da ta dace, wanda ya kamata a kula da su:
