I-Self-Contained Breathing Apparatus (SCBA) iwucezu lwesisetshenziswa olubalulekile kunoma ubani odinga ukusebenza ezindaweni lapho umoya ungaphephile khona ukuze uphefumule. Kungakhathaliseki ukuthi izicishamlilo ezilwa nomlilo, izisebenzi zokuhlenga ezingena esakhiweni esibhidlikile, noma izisebenzi zezimboni eziphethe amakhemikhali ayingozi, amasistimu e-SCBA ahlinzeka ngomoya ohlanzekile odingekayo ukuze uphile kulezi zimo eziyingozi. Kulesi sihloko, sizongena emisebenzini ye-SCBA, sigxile kakhulu endimeni yeisilinda esiyinhlanganisela ye-carbon fibres, ezibalulekile ekusebenzeni nokuphepha kwalezi zinhlelo.
Yini i-SCBA?
I-SCBA imele i-Self-Contained Breathing Apparatus. Kuyidivayisi egqokwa abantu ngabanye ukunikeza umoya ophefumulayo ezindaweni lapho umoya ungase ungcole noma unganele ukuphefumula okuvamile. Izinhlelo ze-SCBA zivame ukusetshenziswa izicishamlilo, abasebenzi bezimboni, nabaphenduli bezimo eziphuthumayo. Lolu cingo luqukethe izingxenye ezimbalwa ezibalulekile: ahigh-pressure air cylinder, isilawuli sokucindezela, isifihla-buso, nesistimu yepayipi lokuxhuma.
Umsebenzi we-SCBA
Umsebenzi oyinhloko we-SCBA ukunikeza umsebenzisi umoya ohlanzekile, ophefumulayo ezindaweni lapho umoya ozungezile uyingozi noma ungaphefumuleki. Lokhu kufaka phakathi izindawo ezigcwele intuthu, amagesi anobuthi, noma izindawo ezinamaleveli komoyampilo aphansi. Isistimu ivumela ogqokile ukuthi asebenze ngokuphepha isikhathi esithile, kuye ngomthamo we-isilinda somoyakanye nezinga lokusetshenziswa.
Izingxenye ze-SCBA
1.Imaski Yobuso: Imaski yobuso yakhelwe ukudala isivalo esiqinile ebusweni bomsebenzisi, iqinisekisa ukuthi akukho moya ongcolile ongangena. Ifakwe i-visor ecacile ukuze inikeze ukubonakala ngenkathi ivikela amehlo entuthuni noma kumakhemikhali.
2.I-Pressure Regulator: Lo mshini wehlisa umfutho ophezulu womoya kusilinda ube sezingeni eliphefumulayo. Iqinisekisa ukugeleza komoya okuzinzile kumsebenzisi, ngaphandle kokunaka umoya osele kusilinda.
3.Isistimu yeHose: Ipayipi lixhuma i-isilinda somoyakumaski obuso kanye nesilawuli, okuvumela umoya ukuthi ugeleze usuka kusilinda uye kumsebenzisi.
4.I-Air Cylinder: Iisilinda somoyakulapho umoya ohlanzekile nocindezelwe ugcinwa khona. Yilapho ubuchwepheshe be-carbon fiber composite budlala indima ebalulekile.
Ukubaluleka kweI-Carbon Fiber Composite Cylinders
Iisilinda somoyaingenye yezingxenye ezibaluleke kakhulu ze-SCBA. Igcina umoya ocindezelwe umsebenzisi awuphefumulayo, futhi impahla yesilinda ingathinta kakhulu ukusebenza nokuphepha kwesistimu ye-SCBA.
Ngokwesiko,isilinda somoyas zazenziwe ngensimbi noma nge-aluminium. Nakuba lezi zinto ziqinile, zibuye zisindwe. Lesi sisindo singaba umthwalo obalulekile kubasebenzisi, ikakhulukazi ezimeni ezinzima ngokomzimba ezifana nemisebenzi yokucisha umlilo noma yokuhlenga. Ukuphatha amasilinda asindayo kunganciphisa ukuhamba kwesisebenzi, kwandise ukukhathala, futhi kungase kubambezele isikhathi sokuphendula ezimweni ezibucayi.
Lapha kulaphoisilinda esiyinhlanganisela ye-carbon fibres uyadlala. I-Carbon fiber iyinto eyaziwa ngesilinganiso sayo esiphezulu samandla nesisindo. Lapho isetshenziswa kuI-SCBA cylinders, izinhlanganisela ze-carbon fibre zinikeza amandla adingekayo okugcina ngokuphephile umoya onomfutho ophezulu ngenkathi ulula kakhulu kunezisilinda zensimbi noma ze-aluminium.
Izinzuzo zeI-Carbon Fiber Composite Cylinders
1.Yehlisa Isisindo: I-carbon fibre cylinders alula kakhulu kunozakwabo bensimbi noma be-aluminium. Lokhu kwehliswa kwesisindo kuhumushela ekunyakazeni okukhuphukile kanye nobunzima obuncane bomzimba kumsebenzisi. Isibonelo, isicishamlilo esigqoke i-SCBA ngei-carbon fibre cylinders inganyakaza ngokushesha okukhulu nangokukhathala okuncane, okubalulekile ezimeni ezinengcindezi ephezulu.
2.Amandla aphezulu kanye Nokuqina: Naphezu kokuba nesisindo esincane,i-carbon fibre cylinders ziqine ngendlela emangalisayo. Bangakwazi ukumelana nezingcindezi eziphezulu ezidingekayo ukuze kugcinwe umoya ocindezelweyo (ngokuvamile kufika ku-4,500 psi noma ngaphezulu) ngaphandle kokubeka engcupheni ukuphepha. Lawa masilinda nawo ahlala isikhathi eside futhi amelana nokulimala okuvela emithelela noma izimo zemvelo ezinzima.
3.Impilo Yesevisi Eyengeziwe: Isilinda esiyinhlanganisela ye-carbon fibres bavame ukuba nempilo ende yesevisi uma kuqhathaniswa nezinto zendabuko. Lokhu kuzenza zingabizi kakhulu ngokuhamba kwesikhathi, njengoba zingadingi ukushintshwa njalo. Ukugcinwa okuvamile nokuhlolwa kwe-hydrostatic kungasiza ukuqinisekisa ukuthi la masilinda ahlala ephephile futhi esebenza ngokuhamba kwesikhathi.
4.Ukumelana Nokugqwala: Ngokungafani namasilinda ensimbi,isilinda esiyinhlanganisela ye-carbon fibres abajwayele ukugqwala. Lokhu kubaluleke kakhulu ezindaweni lapho i-SCBA ingase ichayeke khona kumswakama noma amakhemikhali abolayo. Ukumelana nokugqwala kwe-carbon fiber kusiza ukuqinisekisa ubuqotho nokuphepha kwesilinda ngokuhamba kwesikhathi.
Izicelo ze-SCBA ngeI-Carbon Fiber Cylinders
Amasistimu e-SCBA aneisilinda esiyinhlanganisela ye-carbon fibres zisetshenziswa ezindaweni ezahlukene:
1.Ukucima umlilo: Izicishamlilo zivame ukusebenza ezindaweni ezigcwele intuthu lapho umoya ungaphephile ukuwuphefumula. Imvelo engasindi yei-carbon fibre cylinders ivumela abacimi bomlilo ukuthi baphathe imishini yabo kalula, okubenza bakwazi ukuhamba ngokushesha nangempumelelo ezimweni ezisongela ukuphila.
2.Izilungiselelo Zemboni: Ezimbonini lapho abasebenzi bengase bachayeke kumagesi anobuthi noma izindawo ezinomoya-mpilo omncane, amasistimu e-SCBA abalulekile ukuze aphephe. Isisindo esincishisiwe sei-carbon fibre cylinders isiza abasebenzi ukuthi balondoloze amandla ngesikhathi eside besebenzisa.
3.Imisebenzi yokuhlenga: Abaphenduli besimo esiphuthumayo ngokuvamile badinga ukungena ezindaweni ezivaliwe noma izindawo eziyingozi. Imvelo engasindi futhi eqinile yei-carbon fibre cylinders ithuthukisa ikhono labo lokwenza ukuhlenga ngokushesha nangokuphepha.
Isiphetho
Amasistimu e-SCBA angamathuluzi abalulekile okuqinisekisa ukuphepha ezindaweni eziyingozi, kanye nendima yeisilinda esiyinhlanganisela ye-carbon fibres kulezi zinhlelo azikwazi ukweqisa. Ngokunciphisa kakhulu isisindo semishini ngenkathi kugcinwa amandla nokuqina,i-carbon fibre cylinders ukuthuthukisa ukusebenza kwezinhlelo ze-SCBA, zizenze zisebenze kahle futhi zithembeke. Noma ngabe kukucima umlilo, emsebenzini wezimboni, noma emisebenzini yokuhlenga izimo eziphuthumayo, izinhlelo ze-SCBA ngei-carbon fibre cylinderihlinzeka ngomsebenzi obalulekile wokuletha umoya ophephile, ophefumulayo lapho udingeka kakhulu.
