Ni ubuhe bwoko bwa SCBA Abashinzwe kuzimya umuriro bakoresha?

Abashinzwe kuzimya umuriro bishingikiriza ku bikoresho byo guhumeka byonyine (SCBA) kugira ngo birinde imyuka yangiza, umwotsi, hamwe n’ibidukikije bya ogisijeni mu gihe cyo kuzimya umuriro. SCBA nigice cyingenzi cyibikoresho byo kurinda umuntu ku giti cye, bituma abashinzwe kuzimya umuriro bahumeka neza mugihe bakemura ibibazo bishobora guteza akaga. SCBA igezweho ikoreshwa nabashinzwe kuzimya umuriro iratera imbere cyane, ihuza ibice bitandukanye kugirango umutekano, ihumure, kandi birambe. Kimwe mu bintu byingenzi bigize sisitemu ya kijyambere ya SCBA ni ugukoreshakaruboni fibre ikora silinderis, itanga inyungu zingenzi mubijyanye n'uburemere, kuramba, no koroshya imikoreshereze.

Iyi ngingo iracengera muburyo bwa SCBAs abashinzwe kuzimya umuriro bakoresha, bibanda cyane cyane ku ruhare rwakaruboni fibre ikora silinderis n'impamvu bahinduka amahitamo asanzwe mubikoresho byo kuzimya umuriro.

Ibigize SCBA

Sisitemu ya SCBA ikoreshwa nabashinzwe kuzimya umuriro igizwe nibice byinshi byingenzi:

1. Ikirere:Uwitekasilinderini igice cya SCBA kibika umwuka uhumeka munsi yumuvuduko mwinshi, bigatuma abashinzwe kuzimya umuriro bahumeka ahantu habi.
2. Igenzura ry'ingutu hamwe na Hose:Ibi bice bigabanya umwuka wumuvuduko mwinshi wabitswe muri silinderi kugeza kurwego ruhumeka, hanyuma bigashyikirizwa inkongi y'umuriro binyuze muri mask.
3. Mask yo mu maso (Facepiece):Mask yo mumaso ni igifuniko gifunze kirinda isura yumuriro mugihe utanga umwuka. Yashizweho kugirango itange kashe ikomeye kugirango irinde umwotsi na gaze zangiza kwinjira muri mask.
4. Harness and Backplate:Sisitemu ya harness ituma SCBA mumubiri wumuriro, ikwirakwiza uburemere bwa silinderi kandi ikemerera uyikoresha kugenda mubuntu.
5. Sisitemu yo kumenyesha no gukurikirana:SCBA zigezweho akenshi zirimo sisitemu yo gutabaza iburira abashinzwe kuzimya umuriro niba umwuka wabo ari muke cyangwa niba sisitemu ihuye nikibazo.

Ubwoko bwa Cylinders zo mu kirere mu kuzimya umuriro SCBA

Ikirere cyo mu kirere ni cyo kintu cy'ingenzi kigize SCBA, kuko gitanga umwuka uhumeka. Cilinders ishyirwa mubyiciro cyane cyane nibikoresho bikozwemo, hamwe nicyuma, aluminium, nakaruboni fibre ikora silinderis. Mubisabwa byo kuzimya umuriro,karuboni fibre ikora silinderis bikunze guhitamo kubera ibyiza byabo byinshi.

Amashanyarazi

Amashanyarazi y'icyuma ni amahitamo gakondo kuri SCBAs kandi azwiho kuramba n'ubushobozi bwo guhangana n'umuvuduko mwinshi. Nyamara, silinderi yicyuma iraremereye, ituma idakunda cyane kuzimya umuriro. Uburemere bwa silindiri yicyuma burashobora kugora abashinzwe kuzimya umuriro kugenda vuba kandi neza, cyane cyane mubidukikije bikabije nko gutwika inyubako.

Aluminium Cylinders

Amashanyarazi ya aluminiyumu yoroshye kuruta ibyuma ariko aracyaremereye kuruta karuboni fibre yibikoresho. Zitanga impirimbanyi nziza hagati yikiguzi nuburemere ariko ntishobora gutanga urwego rumwe rwo guhumuriza cyangwa koroshya kugenda nka silindari ya karubone mumikorere yagutse yo kuzimya umuriro.

Carbone Fibre Composite Cylinders

Caribre fibre igizwe na silinderis byagaragaye nkuburyo bwatoranijwe kuri sisitemu ya kijyambere ya SCBA ikoreshwa nabashinzwe kuzimya umuriro. Iyi silinderi ikozwe mugupfunyika umurongo w'imbere (mubisanzwe bikozwe muri aluminium cyangwa plastike) hamwe na fibre ya karubone, nikintu cyoroshye kandi gikomeye cyane. Igisubizo ni silinderi ishobora gufata umwuka kumuvuduko mwinshi cyane mugihe yoroshye cyane kuruta ibyuma cyangwa aluminiyumu.

Ibyiza byaCarbone Fibre Composite Cylinders:

1. Umucyo: Caribre fibre igizwe na silinderis biroroshye cyane kuruta ibyuma na aluminiyumu. Uku kugabanuka kwibiro kurashobora guhindura itandukaniro rikomeye mugihe kirekire cyo kuzimya umuriro, aho ubushobozi bwo kugenda vuba kandi neza nibyingenzi.
2. Kuramba:Nubwo yoroshye,karuboni fibre ikora silinderis birakomeye bidasanzwe kandi biramba. Barashobora kwihanganira imikazo myinshi kandi ntibashobora kwangizwa ningaruka, bigatuma bikwiranye nubuzima bubi abashinzwe kuzimya umuriro bahura nazo.
3. Kurwanya ruswa:Bitandukanye n'ibyuma,karuboni fibre silinderis ntugire ingese, izamura kuramba kandi igabanya ibikenewe kubungabungwa kenshi.
4. Ubuzima Burebure Kumurimo:Ukurikije ubwoko bwa silinderi,karuboni fibre ikora silinderis bafite ubuzima bwa serivisi kugeza kumyaka 15 (Andika 3), mugihe bimwe bishyaAndika silinderi 4 hamwe na PET liners irashobora no kutagira igihe cyubuzima bwa serivisi mubihe bimwe. Ibi bituma bashora imari ihendutse mugihe kirekire.
5. Ubushobozi bwo mu kirere bwo hejuru:Bitewe nubushobozi bwabo bwo gufata umwuka kumuvuduko mwinshi,karuboni fibre ikora silinderis kwemerera abashinzwe kuzimya umuriro gutwara umwuka mwinshi muri pake yoroheje. Ibi bivuze ko bashobora kuguma ahantu hashobora guteza akaga igihe kirekire badakeneye guhindura silinderi.

NiguteCaribre Fibre Cylinders Wungukire Abashinzwe kuzimya umuriro

Abashinzwe kuzimya umuriro bakeneye kugenda vuba kandi bagakora mubihe bikomeye, kandi ibikoresho bitwaye ntibigomba kubitindaho.Caribre fibre igizwe na silinderis nigisubizo cyiki kibazo, gitanga inyungu zingenzi zizamura neza imikorere yabashinzwe kuzimya akazi.

Kugenda neza

Uburemere bworoshye bwakaruboni fibre silinderis bivuze ko abashinzwe kuzimya umuriro baremerewe cyane nibikoresho byabo. Amashanyarazi gakondo arashobora gupima ibiro birenga 25, ibyo bikaba byongera abashinzwe kuzimya umuriro basanzwe bambaye imyenda iremereye kandi bitwaje ibikoresho byiyongera.Amashanyarazi ya karubones, bitandukanye, irashobora gupima munsi ya kimwe cya kabiri cyayo. Uku kugabanya ibiro bifasha abashinzwe kuzimya umuriro gukomeza kwihuta no kwihuta, nibyingenzi mugihe ugenda unyuze mumazu yuzuyemo umwotsi cyangwa kuzamuka ingazi mugihe cyihutirwa.

Kwiyongera kw'itangwa ry'ikirere kubikorwa birebire

Iyindi nyungu yakaruboni fibre ikora silinderis nubushobozi bwabo bwo kubika umwuka kumuvuduko mwinshi-mubisanzwe 4.500 psi (pound kuri santimetero kare) cyangwa irenga, ugereranije numuvuduko muke mubyuma cyangwa silindini ya aluminium. Ubu bushobozi buhanitse butuma abashinzwe kuzimya umuriro batwara umwuka uhumeka utarinze kongera ubunini cyangwa uburemere bwa silinderi, bibafasha kuguma ku kazi igihe kirekire badakeneye gusubira inyuma kugirango bahindure silinderi.

Kuramba mubidukikije bikaze

Kurwanya inkongi y'umuriro birasaba umubiri kandi bibera ahantu hateye akaga aho ibikoresho bihura nubushyuhe bwinshi, imyanda ikarishye, hamwe no gufata nabi.Caribre fibre igizwe na silinderis zagenewe guhangana nizi mbogamizi. Gufunga fibre ya karubone itanga ubundi buryo bwo kwirinda ingaruka nizindi mbaraga zituruka hanze, bigabanya amahirwe yo kwangirika no kuzamura ubwizerwe muri rusange bwa sisitemu ya SCBA.

Kubungabunga no Gukora Ubuzima

Amashanyarazi ya karubones, cyane cyaneAndika silinderi 3s hamwe na aluminiyumu, mubisanzwe ufite ubuzima bwimyaka 15. Muri iki gihe, bagomba kugenzurwa buri gihe no kwipimisha kugirango umutekano wabo ukore.Andika silinderi 4, ikoresha plastike (PET), irashobora kugira ubuzima butagira imipaka bitewe nikoreshwa no kwitabwaho. Ubu buzima bwagutse bwa serivisi nindi nyungu itangakaruboni fibre silinderisa guhitamo bifatika kubashinzwe kuzimya umuriro.

Umwanzuro

Abashinzwe kuzimya umuriro bahura n’akaga gashobora guhitana ubuzima bwabo mu kazi kabo, kandi biterwa n’ibikoresho byabo kugira ngo babungabunge umutekano. Sisitemu ya SCBA nigice cyingenzi mubikoresho byabo byo kubarinda, kandi silinderi yo mu kirere igira uruhare runini mu gutuma umwuka uhumeka uhoraho ahantu habi.Caribre fibre igizwe na silinderis byahindutse ihitamo rya sisitemu ya SCBA mukuzimya umuriro kubera uburemere bwabyo, burambye, nubushobozi buhanitse. Iyi silinderi itanga inyungu zikomeye kurenza ibyuma gakondo na aluminiyumu, byongera umuvuduko, ihumure, nuburyo bukoreshwa nabashinzwe kuzimya umuriro. Nka tekinoroji ya SCBA ikomeje gutera imbere,karuboni fibre silinderis izakomeza kuba ikintu cyingenzi mugutezimbere umutekano wumuriro nibikorwa.
