Isixhobo sokuphefumla esinezixhobo (i-SCBA) sisiqwenga esibalulekileyo sezixhobo zomntu ngamnye ekufuneka esebenza kwiindawo apho umoya awukhuselekanga khona ukuphefumla. Nokuba ngaba ngabacimi bomlilo balwa nolwakhiwo, abahlanguli abangena kwisakhiwo esiwileyo, okanye abasebenzi beshishini abaphatha iikhemikhali eziyingozi, iinkqubo ze-SBA zibonelela ngomoya ococekileyo ofunekayo ukuze uphile kule meko inobungozi. Kweli nqaku, siya kungena kwimisebenzi ye-SCA, kugxilwe ikakhulu kwindima yeI-carbon fiber ye-carbon sylinders, ebaluleke kakhulu kwintsebenzo kunye nokhuseleko lwezi nkqubo.
Yintoni i-SCBA?
I-SCBA imele izixhobo zokuziphethe kakuhle. Sisixhobo esinxitywa ngabantu ukuba banike umoya ophefumlayo kwiindawo apho umoya unokungcoliseka khona okanye ongonelanga ukuphefumla okuqhelekileyo. Iinkqubo ze-SCBA zihlala zisetyenziswa ngabacimi-mlilo, abasebenzi bezishishini, kunye nabaphenduli kaxakeka. Isixhobo sinezinto ezininzi eziphambili: Aisilinda esiphezulu esiphezulu, umlawuli woxinzelelo, imaski yobuso, kunye nenkqubo ye-hose yokudibanisa.
Umsebenzi we-SCBA
Umsebenzi ophambili we-sba kukubonelela ngomsebenzisi ngomoya ococekileyo, ophefumlayo kwiindawo apho umoya ojikelezileyo uyingozi okanye ungenakukrelekrele. Oku kubandakanya iindawo ezizaliswe ngumsi, igesi enetyhefu, okanye imeko enenqanaba le-oxygen esezantsi. Inkqubo ivumela umntu ongubani na ukuba asebenze ngokukhuselekileyo kangangexesha elithile, kuxhomekeke kubungakanani beisilinda somoyakunye nenqanaba lokusebenzisa.
Izinto ze-scba
1. Imaski yemaski: Imaski yobuso yenzelwe ukwenza itywina eliqinileyo elijikeleze ubuso bomsebenzisi, ukuqinisekisa ukuba akukho moya ungcolisekileyo unokungena. Ixhotywe nge-visor ecacileyo ukubonelela ngokubonakala ngelixa ndikhusela amehlo kumsi okanye kwimichiza.
2.Umlawuli: Esi sixhobo sinciphisa uxinzelelo oluphezulu lomoya kwisilinda ukuya kwinqanaba eliphefumlelweyo. Iqinisekisa ukuhamba komoya okhohlakeleyo kumsebenzisi, ngaphandle komoya osele kwi-cylinder.
Inkqubo yeNkqubo: I-Hose idibanisaisilinda somoyaKwimaski yobuso kunye noMlawuli, ukuvumela umoya ukuba uhambe kwi-cylinder kumsebenzisi.
4.Isilinda somoya: Iisilinda somoyaKulapho kugcinwa khona umoya ococekileyo, oxinzelelweyo. Kulapho itekhnoloji ye-carbon ye-fiber idlala indima ebalulekileyo.
Ukubaluleka kweI-carbon fiber ye-carbon sylinders
Iisilinda somoyayenye yezona zinto zibalulekileyo ze-sba. Igcina umoya oxinzelelweyo owuphefumlayo owuphefumlayo, kwaye umxholo wesilinda unokuyichaphazela kakhulu intsebenzo kunye nokhuseleko lwenkqubo ye-SBA.
Ngokwesiko,isilinda somoyazenziwe ngentsimbi okanye i-aluminium. Ngelixa ezi zixhobo zomelele, nazo zinzima. Esi sisindo sinokuba ngumthwalo obalulekileyo kubasebenzisi, ngakumbi kwiimeko ezifunwa ngokomzimba njengemisebenzi yokucima umlilo okanye yokuhlangula. Ukuthwala iisilinda ezinzima kunokunciphisa ukuhamba komsebenzi, ukwandisa ukudinwa, kwaye oku kunokuba lula ixesha lokuphendula kwiimeko ezinzima.
KulaphoI-carbon fiber ye-carbon sylinderSiza kudlala. I-carbon fiber yinto eyaziwa ngokuba yinxalenye yayo ephakamileyo. Xa isetyenziswe ngaphakathiI-SCBA CylinderS, izihlunu ze-carbon fiber zibonelela ngamandla afanelekileyo ukugcina umoya ogcina uxinzelelo oluphezulu ngelixa ulula kakhulu kunentsimbi okanye i-aluminium cylinds.
Izibonelelo zeI-carbon fiber ye-carbon sylinders
I-Baeredud ubunzima: I-carbon fiber cylinderzilula kakhulu kunentsimbi yentsimbi okanye i-aluminium. Olu kuncitshiswa kobunzima buguqulela ukusasazeka kunye nokuhamba kancinci komzimba kumsebenzisi. Umzekelo, ukubopha umlilo okunxibe i-sca kunyeI-carbon fiber cylinders unokuhamba ngokukhawuleza ngakumbi kwaye ungakhathali kangako, ebaluleke kakhulu kwiimeko zengcinezelo eziphezulu.
I-2.ighgh amandla kunye nokuqina: Ngaphandle kokuba lukhaphukhaphu,I-carbon fiber cylinderzomelele kakhulu. Banokumelana noxinzelelo oluphezulu olufunekayo ukugcina umoya oxinzelelweyo (uhlala kwi-4 500 psi okanye ngaphezulu) ngaphandle kokwenza ukhuseleko. Ezi zilinda ziyaqhubeka kwaye zixhathise ukonakala kwiimpembelelo okanye kwiimeko ezikhoyo zokusingqongileyo.
3.Ubomi benkonzo: I-carbon fiber ye-carbon sylinders ihlala inobomi benkonzo obude xa kuthelekiswa nezinto zesiko. Oku kubangela ukuba babe neendleko zokusebenza ngakumbi ekuhambeni kwexesha, njengoko akufuneki batshintshwe rhoqo. Uvavanyo rhoqo kunye novavanyo lwe-hydrostatic lunokunceda ukuba ezi zilinda zihlala zikhuselekile kwaye zisebenza ngokuhamba kwexesha.
4.UkuxhaphazaNgokungafaniyo neesilinda zentsimbi,I-carbon fiber ye-carbon sylinders akahambelani ekusuleni. Oku kubaluleke kakhulu kwiimeko apho i-SCBA ingavezwa khona ukufuma okanye ukuthoba izikhemikhali. Ukuxhathisa i-corrosion yefayibha yekharbhon kunceda ekuqinisekiseni ingqibelelo ye-cylinder kunye nokhuseleko ekuhambeni kwexesha.
Izicelo ze-SCBA ngeI-carbon fiber cylinders
Iinkqubo ze-SCBA kunyeI-carbon fiber ye-carbon sylinderIsetyenziswe kwiindawo ezahlukeneyo:
1.Firefight: Abacimi-mlilo bahlala besebenza kwindawo ezaliswe yintsimi apho umoya ungakhuselekanga ukuphefumla. Ubume bokukhanya kweI-carbon fiber cylinderSivumela abacimi-mlilo ukuba baphathe ngokulula izixhobo ngokulula, bebenza ukuba bahambe ngokukhawuleza nangokufanelekileyo kwiimeko ezisongela ubomi.
I-APETSUSIUSETS: Kumzi-mveliso apho abasebenzi banokuvezwa ziigesi ezinetyhefu okanye iindawo eziphantsi zeoksijini, iinkqubo ze-SBA zibalulekile ukuze zikhuseleke. Ubunzima obuncitshisiweyoI-carbon fiber cylindersukunceda abasebenzi bagcine amaqela ngexesha lemisebenzi eyandisiweyo.
Imisebenzi ye-3.rescue: Abaphenduli bakaxakeka kudla ngokufuna ukufaka izithuba ezivaliweyo okanye iindawo eziyingozi. Ukukhanya okukhanyayo kunye nokuhlala ixeshaI-carbon fiber cylinderUkongeza amandla abo okwenza ukuba ahlangulwe ngokukhawuleza nangokukhuselekileyo.
Ukuqukumbela
Iinkqubo ze-SCBA zizinto ezibalulekileyo zokuqinisekisa ukhuseleko kwiindawo ezinobungozi, kunye nendima yeI-carbon fiber ye-carbon sylinders kwezi nkqubo azinakuba ngaphezulu. Ngokunciphisa ubunzima bomzimba wezixhobo ngelixa ugcina amandla kunye nokuqina,I-carbon fiber cylinderUkomeleza ukusebenza kweenkqubo ze-SBA, kubenza basebenze ngakumbi kwaye bathembeke. Nokuba kukucima umlilo, umsebenzi wamashishini, okanye imisebenzi engxamisekileyo, iinkqubo ze-SCBA kunyeI-carbon fiber cylinderUkubonelela umsebenzi obalulekileyo wokuhambisa umoya okhuselekileyo, ophefumlayo xa kufuneka uninzi.
