I-Self-Contained Breathing Apparatus (SCBA) sisixhobo esibalulekileyo kuye nabani na ofuna ukusebenza kwindawo apho umoya ungakhuselekanga ukuphefumla. Ingaba ngabacimi bomlilo abalwa nomlilo, abasebenzi bokuhlangula abangena kwisakhiwo esidilikileyo, okanye abasebenzi bemizi-mveliso abaphethe imichiza eyingozi, iinkqubo ze-SCBA zibonelela ngomoya ococekileyo ofunekayo ukuze uphile kwezi meko ziyingozi. Kweli nqaku, siza kuntywila kwimisebenzi ye-SCBA, sigxile kakhulu kwindima yecarbon fiber composite cylinders, ezibalulekileyo ekusebenzeni nasekukhuselekeni kwezi nkqubo.
Yintoni iSCBA?
I-SCBA imele iSelf-Contained Breathing Apparatus. Sisixhobo esinxitywa ngabantu ngabanye ukunika umoya ophefumlayo kwindawo apho umoya unokuthi ungcoliseke okanye ungonelanga ukuphefumla okuqhelekileyo. Iinkqubo ze-SCBA ziqhele ukusetyenziswa ngabacimi bomlilo, abasebenzi bamashishini, kunye nabaphenduli bexakeka. Isixhobo sinezixhobo ezininzi eziphambili: aisilinda somoya woxinzelelo oluphezulu, isilawuli soxinzelelo, isigqubuthelo sobuso, kunye nenkqubo yepayipi yokuxhuma.
Umsebenzi weSCBA
Umsebenzi ophambili we-SCBA kukubonelela umsebenzisi ngomoya ococekileyo, ophefumlayo kwiindawo apho umoya ojikelezayo unobungozi okanye ungaphefumli. Oku kuquka iindawo ezizaliswe ngumsi, iigesi ezinetyhefu, okanye iindawo ezisingqongileyo ezinamaqondo aphantsi oksijini. Inkqubo ivumela umntu onxibileyo ukuba asebenze ngokukhuselekileyo ixesha elithile, kuxhomekeke kumthamo weisilinda somoyakunye nesantya sokusetyenziswa.
Amacandelo eSCBA
1.Imaski yobuso: Imaski yobuso yenzelwe ukwenza itywina eliqinileyo malunga nobuso bomsebenzisi, ukuqinisekisa ukuba akukho moya ongcolileyo unokungena. Ixhotywe nge-visor ecacileyo ukubonelela ngokubonakalayo ngelixa ukhusela amehlo kumsi okanye kwiikhemikhali.
2.I-Pressure Regulator: Esi sixhobo sinciphisa uxinzelelo oluphezulu lomoya kwi-cylinder ukuya kwinqanaba lokuphefumla. Iqinisekisa ukuhamba komoya okuzinzileyo kumsebenzisi, kungakhathaliseki ukuba umoya oseleyo kwi-cylinder.
3.Inkqubo yeHose: Umbhobho udibanisa iisilinda somoyakwimaski yobuso kunye nomlawuli, ukuvumela umoya ukuba uphume kwi-cylinder ukuya kumsebenzisi.
4.Isilinda somoya: Iisilinda somoyakulapho umoya ococekileyo nocinezelweyo ugcinwa khona. Kulapho iteknoloji ye-carbon fiber composite idlala indima ebalulekileyo.
Ukubaluleka kweI-Carbon Fiber Composite Cylinders
Iisilinda somoyalelinye lawona macandelo abalulekileyo e-SCBA. Igcina umoya oxinyiweyo ophefumlwa ngumsebenzisi, kwaye izinto ze-cylinder zinokuchaphazela kakhulu ukusebenza kunye nokhuseleko lwenkqubo ye-SCBA.
Ngokwemveli,isilinda somoyas zenziwe ngentsimbi okanye ialuminiyam. Nangona ezi zixhobo zomelele, zikwanzima. Lo bunzima bunokuba ngumthwalo obalulekileyo kubasebenzisi, ngakumbi kwiimeko ezifunwa ngumzimba ezifana nokucima umlilo okanye imisebenzi yokuhlangula. Ukuthwala iisilinda ezinzima kunokunciphisa ukuhamba komsebenzi, ukwandisa ukudinwa, kwaye kunokucothisa ixesha lokuphendula kwiimeko ezinzima.
Kulaphocarbon fiber composite cylinders ungene kumdlalo. Ifayibha yekhabhoni yimathiriyeli eyaziwa ngamandla ayo aphezulu ukuya kubunzima bomlinganiselo. Xa isetyenziswa kwiI-SCBA cylinders, i-carbon fiber composites inika amandla ayimfuneko ukugcina ngokukhuselekileyo umoya woxinzelelo oluphezulu ngelixa ilula kakhulu kunentsimbi okanye iisilinda ze-aluminium.
Iinzuzo zeI-Carbon Fiber Composite Cylinders
1.Ubunzima obuncitshisiweyo: Ikhabhoni fiber cylinders zikhaphukhaphu kakhulu kunentsimbi okanye i-aluminiyam. Oku kuncitshiswa kobunzima kuguqulela ukunyuka kokuhamba kunye nokunciphisa ubunzima bomzimba kumsebenzisi. Umzekelo, umcimi-mlilo onxibe i-SCBA ngecarbon fiber cylinders inokuhamba ngokukhawuleza ngakumbi kwaye kunye nokudinwa okuncinci, okubalulekileyo kwiimeko zoxinzelelo oluphezulu.
2.Amandla aphezulu kunye nokuqina: Nangona ukhaphukhaphu,carbon fiber cylinderzomelele ngendlela emangalisayo. Bangakwazi ukumelana noxinzelelo oluphezulu olufunekayo ukugcina umoya oxinyiweyo (ngokuqhelekileyo ukuya kwi-4,500 psi okanye ngaphezulu) ngaphandle kokunciphisa ukhuseleko. Ezi zisilinda zikwahlala ixesha elide kwaye zixhathisa umonakalo ovela kwiimpembelelo okanye iimeko ezinzima zokusingqongileyo.
3.Ubomi beNkonzo eyandisiweyo: Ikhabhon fiber composite cylinders badla ngokuba nobomi benkonzo obude xa kuthelekiswa nezinto zemveli. Oku kubenza bangabizi kakhulu ekuhambeni kwexesha, njengoko kungafuneki ukuba batshintshwe rhoqo. Ukugcinwa rhoqo kunye novavanyo lwe-hydrostatic lunokunceda ukuqinisekisa ukuba ezi silinda zihlala zikhuselekile kwaye zisebenza ngexesha.
4.UKunyangwa kokuMhlwa: Ngokungafaniyo neesilinda zentsimbi,carbon fiber composite cylinders azithandeki kumhlwa. Oku kubaluleke ngakumbi kwiindawo apho i-SCBA inokuthi ibe sesichengeni sokufuma okanye iikhemikhali ezonakalisayo. Ukunganyangeki kwe-corrosion ye-carbon fiber inceda ukuqinisekisa ingqibelelo ye-cylinder kunye nokhuseleko ekuhambeni kwexesha.
Usetyenziso lwe-SCBA ngeCarbon Fiber Cylinders
iinkqubo SCBA ngecarbon fiber composite cylinders zisetyenziswa kwiindawo ezahlukeneyo:
1.Ukucima umlilo: Abacimi-mlilo bahlala besebenza kwiindawo ezizele ngumsi apho umoya ungakhuselekanga ukuphefumla. Ubume obukhaphukhaphu becarbon fiber cylinders ivumela abacimi bomlilo ukuba baphathe izixhobo zabo ngokulula, okubenza bakwazi ukuhamba ngokukhawuleza nangokufanelekileyo kwiimeko ezisongela ubomi.
2.Iisetingi zeMveliso: Kumashishini apho abasebenzi banokuthi bavezwe kwiigesi ezinetyhefu okanye iindawo ezine-oksijini ephantsi, iinkqubo ze-SCBA ziyimfuneko kukhuseleko. Ubunzima obuncitshisiweyo becarbon fiber cylinders inceda abasebenzi bagcine amandla ngexesha elongeziweyo lokusetyenziswa.
3.Imisebenzi yokuHlangula: Abaphenduli bexesha likaxakeka bahlala befuna ukungena kwiindawo ezivaliweyo okanye iindawo ezinobungozi. Ubume obukhaphukhaphu kunye nokuqina kwecarbon fiber cylinders kwandisa amandla abo okwenza uhlangulo ngokukhawuleza nangokukhuselekileyo.
Ukuqukumbela
Iinkqubo ze-SCBA zizixhobo eziyimfuneko zokuqinisekisa ukhuseleko kwiindawo ezinobungozi, kunye nendima yecarbon fiber composite cylinders kwezi nkqubo ayinakuba ngaphezulu. Ngokunciphisa kakhulu ubunzima besixhobo ngelixa ugcina amandla kunye nokuqina,carbon fiber cylinders ukomeleza ukusebenza kweenkqubo zeSCBA, zizenza zisebenze ngakumbi kwaye zithembeke. Nokuba kukucima umlilo, umsebenzi wefektri, okanye uhlangulo olungxamisekileyo, iinkqubo zeSCBA ngecarbon fiber cylinderzibonelela ngomsebenzi obalulekileyo wokuhambisa umoya okhuselekileyo, ophefumlayo xa ufuneka kakhulu.
