Zozimitsa moto zopumira za Elcaratus Meani: Kodi ScA ndi chiyani?

Pakakhala moto woyaka kapena malo ochitira ngozi mafakitale, ozimitsa moto komanso ogwira ntchito za mafakitale amabweza mosasamala, akufuna udindo waukulu woteteza moyo ndi katundu. M'malo owopsawa, pali zida za mtundu wawo wa 'moyo wawo', ndiye kuti, zomwe zidalike zopumira (scba). Kodi ndi chiyani kwenikweni, ndipo ndi malo ogwiritsira ntchito mfundo ziti? Kenako, tiyeni tione mozama.

Kodi Scba: Tanthauzo ndi Mfundo ndi Mfundo?

Pulogalamu yopumira (Scba), yomwe imadziwikanso kuti kupulumutsa kotseguka kapena sc outfight ndipo nthawi zina imatchulapo popumira mpweya (ba), yomwe ndi chipangizo chovala mpweya wabwino mumlengalenga womwe umakhala wowopsa kumoyo kapena thanzi. Amagwiritsidwa ntchito poyatsira moto.
Scba ndi pulogalamu yopumira yoletsedwa yoyendetsa mafakitale osadzaza ndi mpweya wabwino, koma ndi mpweya wabwino wosungunuka. Kapangidwe kameneka kamakhala ndi mwayi wapadera wotha kusintha malo osiyanasiyana komanso owopsa. 'Wodzidalira' ndi gawo lofunikira, kutanthauza kuti sikufunika kudalira mpweya wakunja wopumira, monga mphongo wautali kuti apeze mpweya. Wogwiritsa ntchitoyo ali ndi ufulu kuyenda mozungulira malo osawopsa omwe sanakhalepo ndi mbedza, amalimbikitsa kwambiri kuyenda komanso chitetezo.

Zigawo zikuluzikulu za scba

Chigoba chokwanira

Chigoba chathunthu ndicho chotchinga choyamba pakati pa wogwiritsa ntchito ndi chilengedwe chowopsa. Amapangidwa kuchokera ku zinthu zotsalira kwambiri, zotsutsana ndi zolimba zomwe zimazungulira pa nkhope, mwamphamvu kutseka tinthu toyipa, mpweya ndi utsi. Nthawi yomweyo, gawo lalikulu la mawonekedwe a masomphenya amalola wosuta kuti akhale ndi gawo lowoneka bwino, ngakhale m'malo odzazidwa ndi utsi, kuonetsetsa chitetezo cha mayendedwe.

Woyang'anira

Wogulitsa ndi 'Ubongo wanzeru' wa Scba, womwe ungathe kuyendetsa bwino mpweya ndi kukakamizidwa. Mosasamala kanthu za kugwirizirana kwa wogwiritsa ntchito, kaya mukuyenda tulo kapena wokhazikika, wowongolera, amalola wosuta kuti azigwira ntchito momasuka m'malo owopsa.

Ma Cylinders a Air

Maliriji a mpweya ndi amodzi mwa zigawo za scba ndipo amapezeka mu lita imodzi, malita 6 ndi 6.8. Mitundu yosiyanasiyana ya masilini osiyanasiyana ndioyenera ma prenarios osiyanasiyana. Mwachitsanzo, silinda 4 litayi ndi yaying'ono komanso yopepuka, ndikupangitsa kuti ikhale yoyenera kuti ipulumuke, pomwe 6.8-lita ya litainder ili ndi mphamvu yayikulu yosungirako motalikirana. Maliriji amenewa amapangidwa kawirikawiri kuchokera ku zida zapamwamba monga kaboni, yomwe imatsimikizira chitetezo motetezeka momwe mungathere.

Magulu opanikizika

Zingwe zophatikizika zimaphatikizapo magawano a cylinder opanikizika ndi ma agalu akutali. Magulu a Cylinder amapatsa wogwiritsa ntchito nthawi zonse momwe mpweya umasiyidwira mu silinda yomwe imagwira ntchito moyenerera kuti ikonzedwe moyenera. Magulu akutali, makamaka mitundu yokhala ndi zomwe zimaphatikizidwa (mawonekedwe achitetezo cha Chitetezo cha Chitetezo), ndizovuta kwambiri. Ngati wogwiritsa ntchitoyo akadalipo pamalo owopsa, chipangizocho chidzafuulira alamu, kuchenjeza anzanu omwe akuyambitsa, kuwonjezera chitetezo champhamvu pamoyo wa wogwiritsa ntchito.

Kunyamula chingwe

Chikwangwanichi chimapangidwa ndi ziwopsezo zosinthika ndi lamba wachiuno, zomwe zimatha kusinthasintha molingana ndi thupi la wogwiritsa ntchito. Mwanjira imeneyi, scba imatha kunyamulidwa mwamphamvu thupi la wogwiritsa ntchito, ndipo sadzatopa kwambiri pokulunga kwa nthawi yayitali, ndikuwonetsetsa kuti wogwiritsa ntchitoyo akhoza kukhala ndi ntchito yabwino mukamachita ntchito.

Mitundu ya kupuma ndi gulu la scob

Kuyeretsa mpweya (maprs)

Kutsuka mpweya opuma (mafilimu) adapangidwa kuti achotse zodetsa za mpweya kudzera pakusefa. Amakhala ndi tinthu tating'onoting'ono, chomwe chimasefa zinthu monga fumbi monga fumbi, mungu, ndi zina zopukutira ndi mpweya, zomwe zimapereka kusefedwa kwa mankhwala ndi mpweya. Izi nthawi zambiri zimagwiritsidwa ntchito m'malo owonongeka kwambiri ndipo ndizofala kwambiri m'moyo ndi ntchito zochepa.

Kupuma kwa mpweya (asrs)

Kupuma kwa mpweya (asrs) amapereka mpweya woyenerera kuchokera kosiyana. Amapereka chitetezo chonse motsutsana ndi zodetsa zosiyanasiyana, kuphatikizapo tinthu tating'onoting'ono, mipweya ndi nthunzi, ndipo imagwira ntchito yofunika kwambiri m'matumba opanda mpweya. ScBas ndi mtundu umodzi wa aske ndipo amatenga gawo lofunikira pakuwopseza moyo ndi thanzi (idlh) malo komanso yankho ladzidzidzi.

Kuwonongeka kwa scba

• Kuthawa scbas: kuthawa scbas kumakhala kokha monga zida zobwerera. M'malo ena a malo, chitetezo cha ScBA sichingafunike polowera koyamba, koma chitha kukhala chothandiza pakagwa mwadzidzidzi. Izi zimapangidwira kuti ziziyenda mosalekeza ndipo zimakhala ndi zibowo zosavuta zomwe zitha kuperekedwa mwachangu munthawi yochepa. ScBas ndiyofunikira kwambiri ngati zosunga mwadzidzidzi mukamagwiritsa ntchito masuti a kapena b ma suti ndikudalira mphamvu yopumira.
• Mu / SCBA: mu / SCBB ndiye chisankho chabwino kwambiri pakamveka kuti wogwira ntchito amafunikira tsiku lonse la SCBA yonse. Itha kugwiritsidwa ntchito munjira yotseguka kapena yotsekedwa, ndipo nthawi zambiri imakhala ndi mpweya waukulu kwa nthawi yayitali, yogwira ntchito kwambiri.

Kusamala kuti mugwiritse ntchito SCBA

Zofuna za Oxygen

Ndikofunikira kudziwa kuti mosiyana ndi mpweya wa oxanjgen woyamwa zodziwonongeratu, ScBA imatha kugwiritsidwa ntchito pokhapokha ngati oxygen ndendeyo ndi yochepera 17%. Okondedwa a oxygen akangogwera pansi pa muyeso uwu, wogwiritsa ntchitoyo akhoza kuyang'anizana ndi chiopsezo chakweredwe. Chifukwa chake, musanalowe m'malo owopsa, ndikofunikira kuyang'ana mosamalitsa kwa oxygen omwe ali patsambalo.

Makhalidwe Ake Ogwiritsa Ntchito

Pulogalamu yopumira yokha yopumira ndi chinthu chotulutsa ndikugulitsanso. Kugwiritsa ntchito mobwerezabwereza kumatha kuchepetsedwa kwamphamvu kwambiri pakusintha kwa mpweya woyipa, motero kuwopseza moyo wa wogwiritsa ntchito.
Zambiri Zoteteza Payekha
Ogwiritsa ntchito ndi tsitsi lalitali nthawi zonse amavala scba ndi tsitsi lawo lonse limakhala mkati mwa hood. Izi ndichifukwa choti mpweya woopsa umatha kulowa mu tsitsi kudutsa tsitsi ndikuvulaza wosuta, motero ndikofunikira kuti mumve tsatanetsatane.

Ndizofunikira povala chigoba

Mukavala chigoba cha theka, ndikofunikira kuwonetsetsa kuti chigoba chimakwanira pakamwa ndi mphuno, ndikuti umatha kufulumira kumaso. Ndi kuwonetsetsa kuti muwonetsetse kuti ndi bwino kupewa kutetezedwa ndi mpweya woipa ndikutchinjiriza wodalirika kwa wogwiritsa ntchito.
Yosavuta kuvala magalasi
Kwa oonera owoneka bwino, Scba ikhoza kugwiritsidwa ntchito popanda kufunikira pochotsa zowoneka zawo, ndipo scba yapangidwa ndi izi, popanda kunyalanyaza kuteteza konse kapena kuyambitsa zovuta zina kwa wogwiritsa ntchito.

Chifukwa Chiyani Tiyenera Kusankha Jiu Pai Scba?

Jipaupai amadzipereka kuti apangitse apamwamba - mayunitsi a sunch. Timagwiritsa ntchito kwambiri - zinthu zapamwamba kuti titsimikizire kulimba komanso kudalirika kwa chinthu chilichonse. Maliriji amlengalenga amapangidwa ndi zapamwamba, kupereka mphamvu yosungirako mpweya pomwe ikupepuka. Malamulowa amawongolera - opangidwa kuti apereke mayendedwe osasinthika komanso otetezeka.
Ma scgas athu akugwirizana ndi mfundo zonse zotetezeka, ndikukupatsani mtendere wamalingaliro omwe mukugwiritsa ntchito chinthu chomwe chimakwaniritsa zofunikira kwambiri. Kaya ndinu dipatimenti yoyamika yoyang'ana kuti muteteze oyankha anu oyankha kapena malo opangira mafakitale omwe akufuna kuti antchito anu aziteteza, zinthu zathu scba ndiye chisankho chabwino.
Osanyengerera chitetezo. Wonongerani ndalama mu SCBA lero ndikuwonetsetsa malo otetezeka kwa aliyense.
