Abacimi bomlilo bathembele kwi-Self-Contained Breathing Apparatus (SCBA) ukuze bazikhusele kwiigesi ezinobungozi, umsi, kunye neendawo ezingenayo i-oxygen ngexesha lemisebenzi yokucima umlilo. I-SCBA sisiqwenga esibalulekileyo sesixhobo sokuzikhusela, esivumela abacimi bomlilo ukuba baphefumle ngokukhuselekileyo ngelixa bejongana neemeko ezinobungozi. Ii-SCBA zanamhlanje ezisetyenziswa ngabacimi bomlilo ziphezulu kakhulu, zidibanisa amacandelo ahlukeneyo ukuqinisekisa ukhuseleko, intuthuzelo, kunye nokuqina. Enye yezona zinto zibalulekileyo kwiinkqubo zeSCBA zangoku kukusetyenziswa kwecarbon fiber composite cylinders, ezibonelela ngeenzuzo ezibalulekileyo ngokobunzima, ukuqina, kunye nokulula kokusetyenziswa.
Eli nqaku lihlalutya kwiindidi ze-SCBAs abacimi bomlilo abazisebenzisayo, zijolise ngokukodwa kwindimacarbon fiber composite cylinders kwaye kutheni beba lukhetho oluqhelekileyo kwizixhobo zokucima umlilo.
Amacandelo e-SCBA kunye neentlobo
Inkqubo ye-SCBA esetyenziswa ngabacimi-mlilo iqulathe amacandelo abalulekileyo:
- Isilinda somoya:Iisilinda somoyayinxalenye ye-SCBA egcina umoya ophefumulayo phantsi koxinzelelo oluphezulu, okuvumela abacimi bomlilo ukuba baphefumle kwiindawo ezinobungozi.
- Isilawuli soxinzelelo kunye neeHoses:Ezi zixhobo zinciphisa umoya woxinzelelo oluphezulu olugcinwe kwi-cylinder ukuya kwinqanaba eliphefumulayo, elithunyelwa kumcimi-mlilo ngemaski.
- Isigqubuthelo sobuso (Isigqubuthelo sobuso):Imaski yobuso sisigqubuthelo esitywiniweyo esikhusela ubuso bomcimi-mlilo ngelixa unikezela ngomoya. Yenzelwe ukubonelela ngetywina eliqinileyo ukuthintela umsi kunye neegesi eziyingozi ukuba zingangeni kwimaski.
- Ukubopha kunye ne-Backplate:Inkqubo ye-harness ikhusela i-SCBA kumzimba womcimi-mlilo, ukusabalalisa ubunzima be-cylinder kunye nokuvumela umsebenzisi ukuba ahambe ngokukhululekile.
- IiNkqubo zeAlam kunye nokuBeka iliso:Ii-SCBA zanamhlanje zihlala zibandakanya iinkqubo ze-alam ezidibeneyo ezilumkisa umcimi-mlilo ukuba umoya wabo uphantsi okanye ukuba inkqubo ifumana naluphi na ukungasebenzi kakuhle.
Iintlobo zeeCylinders zoMoya kwi-SCBA yokuCima uMlilo
I-cylinder yomoya ngokuqinisekileyo yeyona nto ibalulekileyo ye-SCBA, njengoko inikezela ngokuthe ngqo umoya ophefumulayo. Iisilinda zihlelwa ikakhulu ngezinto ezenziwe ngazo, ngentsimbi, ialuminiyam, kunyecarbon fiber composite cylinders ukuba yeyona ixhaphakileyo. Kwizicelo zokucima umlilo,carbon fiber composite cylinders zihlala zikhethwa ngenxa yeenzuzo zazo ezininzi.
Iisilinda zentsimbi
Iisilinda zentsimbi zikhethwa ngokwesiko kwii-SCBA kwaye ziyaziwa ngokuhlala kwazo kunye nokukwazi ukumelana noxinzelelo oluphezulu. Nangona kunjalo, iisilinda zentsimbi zinzima, nto leyo eyenza ukuba ingabikho kakuhle ekucimeni umlilo. Ubunzima be-cylinder yensimbi bunokwenza kube nzima kubacimi bomlilo ukuba bahambe ngokukhawuleza nangokufanelekileyo, ngakumbi kwiindawo ezixinzelelekileyo ezifana nezakhiwo ezivuthayo.
Iisilinda zeAluminiyam
Iisilinda ze-aluminiyam zikhaphukhaphu kunentsimbi kodwa zinzima kuneesilinda zekhabhoni zefiber composite. Banikezela ngebhalansi elungileyo phakathi kweendleko kunye nobunzima kodwa abanako ukubonelela ngenqanaba elifanayo lokuthuthuzela okanye ukukhululeka kokuhamba njenge-carbon fiber cylinders kwimisebenzi eyandisiweyo yokucima umlilo.
I-Carbon Fiber Composite Cylinders
Ikhabhon fiber composite cylinders ziye zavela njengokhetho olukhethwayo kwiinkqubo ze-SCBA zanamhlanje ezisetyenziswa ngabacimi bomlilo. Ezi cylinder zenziwe ngokusonga ilina yangaphakathi (eqhele ukwenziwa nge-aluminiyam okanye iplastiki) kunye neengqimba ze-carbon fiber, into ekhaphukhaphu kwaye eyomeleleyo ngokugqithisileyo. Isiphumo sisilinda esinokuthi sibambe umoya kuxinzelelo oluphezulu kakhulu ngelixa sikhaphukhaphu kakhulu kunezinye iintsimbi okanye i-aluminiyam.
Izinto ezilungileyo zeI-Carbon Fiber Composite Cylinders:
- Khaphukhaphu: Ikhabhon fiber composite cylinders zikhaphukhaphu kakhulu kunezo zombini iisilinda zentsimbi kunye ne-aluminiyam. Oku kuncitshiswa kobunzima kunokwenza umehluko omkhulu ngexesha lemisebenzi yokucima umlilo ixesha elide, apho ukukwazi ukuhamba ngokukhawuleza nangokuchanekileyo kubalulekile.
- Ukuqina:Nangona ilula,carbon fiber composite cylinderzomelele ngendlela emangalisayo kwaye zomelele. Bangakwazi ukumelana noxinzelelo oluphezulu kwaye baxhathise umonakalo ovela kwiimpembelelo, okwenza ukuba bafaneleke ngokufanelekileyo kwiimeko ezinzima abacimi-mlilo bahlala bejamelana nazo.
- Ukuxhathisa ukonakala:Ngokungafaniyo nentsimbi,carbon fiber cylinders musa ukugqwala, okwandisa ubomi babo obude kunye nokunciphisa imfuno ukugcinwa rhoqo.
- Ubomi Obude Benkonzo:Ngokuxhomekeke kuhlobo lwesilinda,carbon fiber composite cylinderbaphile ubomi benkonzo ukuya kuthi ga kwiminyaka eyi-15 (Uhlobo lwesi-3), ngelixa ezinye zintshaUhlobo lwe-4 iisilinda ezine-PET linerIsenokungabinamda wobomi benkonzo phantsi kweemeko ezithile. Oku kubenza babe kutyalo-mali olusebenzayo kwixesha elide.
- Umthamo woMoya oPhezulu:Ngenxa yokukwazi kwabo ukubamba umoya kuxinzelelo oluphezulu,carbon fiber composite cylinders ivumela abacimi bomlilo ukuba baphathe umoya ongakumbi kwiphakheji elula. Oku kuthetha ukuba banokuhlala kwiindawo ezinobungozi ixesha elide ngaphandle kokufuna ukutshintsha iisilinda.
NjaniI-Carbon Fiber Cylinders Benefit abacimi-mlilo
Abacimi-mlilo kufuneka bahambe ngokukhawuleza kwaye basebenze kwiimeko ezinzima, kwaye izixhobo abaziphetheyo akufunekanga zithothe isantya.Ikhabhon fiber composite cylinders zisisombululo kulo mngeni, inika iinzuzo ezibalulekileyo eziphucula ngokuthe ngqo ukusebenza kwabacimi-mlilo emsebenzini.
UkuHamba okuPhuculweyo
Ubunzima obulula becarbon fiber cylinders kuthetha ukuba abacimi-mlilo abakho mthwalo omncinci ngezixhobo zabo. Iisilinda zentsimbi zemveli zinobunzima obungaphezu kweekhilogram ezingama-25, ezongeza ubunzima kubacimi bomlilo esele benxibe iimpahla ezikhuselayo ezikhuselayo kwaye bephethe izixhobo ezongezelelweyo.Ikhabhoni fiber cylinders, ngokuchaseneyo, inobunzima obungaphantsi kwesiqingatha saloo mali. Oku kuncitshiswa kobunzima kunceda abacimi bomlilo bagcine i-agility kunye nesantya, eziyimfuneko xa uhamba ngezakhiwo ezizaliswe ngumsi okanye ukunyuka izitebhisi ngexesha likaxakeka.
Ukubonelelwa ngoMoya okwandisiweyo kuSebenzi olude
Enye inzuzo yecarbon fiber composite cylinders amandla abo okugcina umoya kwiingcinezelo eziphezulu-ngokuqhelekileyo i-4,500 psi (iipounds nge-intshi yesikwere) okanye ngaphezulu, xa kuthelekiswa noxinzelelo oluphantsi kwintsimbi okanye iisilinda ze-aluminium. Lo mthamo uphezulu uvumela abacimi bomlilo ukuba baphathe umoya ophefumulayo ngaphandle kokunyusa ubungakanani okanye ubunzima be-cylinder, okubenza bakwazi ukuhlala emsebenzini ixesha elide ngaphandle kokufuna ukuhlehla kwi-cylinder utshintsho.
Ukuhlala ixesha elide kwiNdawo eziBungqwabalala
Ukucima umlilo kufuna ngokwasemzimbeni kwaye kwenzeka kwiindawo ezinobungozi apho izixhobo zibonakaliswe kumaqondo obushushu aphezulu, inkunkuma ebukhali, kunye nokuphathwa kakubi.Ikhabhon fiber composite cylinders ziyilelwe ukumelana nale mingeni. I-carbon fiber wrap inika ukhuseleko olongezelelweyo kwiimpembelelo kunye neminye imikhosi yangaphandle, ukunciphisa amathuba okulimala kunye nokuphucula ukuthembeka okupheleleyo kwenkqubo ye-SCBA.
ULondolozo kunye noBomi beNkonzo
Ikhabhoni fiber cylinders, ngakumbiUhlobo lwe-3 cylinders ezineentsimbi ze-aluminiyam, zihlala zihlala iminyaka eyi-15. Ngeli xesha, kufuneka bahlolwe rhoqo kwaye bavavanywe ukuqinisekisa ukhuseleko kunye nokusebenza kwabo.Uhlobo lwe-4 cylinders, esebenzisa iplastiki (PET) liner, inokuba nobomi obungenamkhawulo ngokuxhomekeke ekusebenziseni kunye nenkathalo. Obu ubomi benkonzo eyandisiweyo yenye inzuzo eyenzacarbon fiber cylindersa ukhetho olusebenzayo kumasebe okucima umlilo.
Ukuqukumbela
