Izinhlelo ze-Self-Contained Breathing Apparatus (SCBA) zibalulekile kubantu abasebenza ezindaweni eziyingozi lapho izinga lomoya lisengozini, njengabacimi bomlilo, abasebenzi bezimboni, namaqembu abatakuli. Ingxenye ebalulekile yezinhlelo ze-SCBA isilinda somfutho ophezulu ogcina umoya ophefumulayo. Eminyakeni yakamuva,i-carbon fibre cylinders bathole ukuvelela ngenxa yezakhiwo zabo eziphakeme uma kuqhathaniswa namasilinda ensimbi yendabuko. Lesi sihloko sihlola indima yei-carbon fibre cylinders ezinhlelweni zesimanje ze-SCBA, izindinganiso zokuphepha ezilawula ukusetshenziswa kwazo, kanye nezinzuzo zazo ngaphezu kwamasilinda ensimbi.
Iqhaza likaI-Carbon Fiber Cylinders ku-Modern SCBA Systems
I-carbon fibre cylinders idlala indima ebalulekile ekuthuthukiseni ukusebenza kwezinhlelo ze-SCBA. Umsebenzi wabo oyinhloko uwukugcina umoya ocindezelwe ezingcindezini eziphezulu, ngokuvamile phakathi kuka-2,200 kuya ku-4,500 psi, okuvumela abasebenzisi ukuthi baphefumule endaweni enezinto eziyingozi noma umoya-mpilo onganele. Ukuthuthukiswa kobuchwepheshe be-carbon fibre kuguqule ukwakheka nokusebenza kwala masilinda, okuwenza abelula futhi aqine kakhudlwana.
Idizayini Engasindi Neqinile
Inzuzo eyinhloko yei-carbon fibre cylinders ilele ekwakhiweni kwabo okungasindi. I-Carbon fibre iyinhlanganisela yezinto ezakhiwe ama-athomu ekhabhoni ahlanganiswe ndawonye esakhiweni sekristalu, esinikeza amandla akhethekile kuyilapho ilula kakhulu kunezinto zendabuko. Le mvelo engasindi yehlisa isisindo sonke sesistimu ye-SCBA, ithuthukisa ukuhamba nokukhuthazela komsebenzisi. Ezimweni eziyingozi, njengokucisha umlilo, amandla okuhamba ngokushesha nangempumelelo kungaba umehluko phakathi kokuphila nokufa.
Ngaphezu kwalokho,i-carbon fibre cylinders zinikeza ukuqina okungenakuqhathaniswa. Impahla eyinhlanganisela imelana kakhulu nomthelela womzimba, ukugqwala, kanye nezingcindezi zemvelo, okuyenza ilungele ukusetshenziswa ezimeni ezimbi kakhulu. Lokhu kuqina kuqinisekisa ukuthi amasilinda agcina ubuqotho bawo besakhiwo ngokuhamba kwesikhathi, okunciphisa ingozi yokwehluleka ngesikhathi sokusebenza okubucayi.
Intuthuko kuCylinder Technology
Intuthuko yakamuva kui-carbon fibre cylinderubuchwepheshe buye bathuthukisa ukusebenza kwe-SCBA. Izinto ezintsha ezifana nezinhlelo ze-resin ezithuthukisiwe kanye nokuqondiswa kwe-fiber okwenziwe kahle kuthuthukise amandla nokumelana nokukhathala kwamasilinda. Lokhu kuthuthukiswa kuvumela izilinganiso zokucindezela okuphezulu kanye nempilo ende yesevisi, okuhlinzeka abasebenzisi ngokuhlinzekwa komoya okwengeziwe kanye nokunciphisa isidingo sokushintshwa kwamasilinda njalo.
Ukwengeza, abakhiqizi benze amasilinda e-carbon fiber ahlakaniphile afakwe izinzwa eziqapha umfutho womoya, izinga lokushisa, nedatha yokusetshenziswa. Lokhu kuhlanganiswa kobuchwepheshe kuvumela ukuqapha nezixwayiso ngesikhathi sangempela, okuvumela abasebenzisi ukuthi benze izinqumo ezinolwazi futhi kuthuthukiswe ukuphepha kukonke phakathi nokusebenza.
Amazinga Okuphepha kanye Nezinqubo Zokuhlola ZeI-Carbon Fiber SCBA Cylinders
Njengoba kunikezwe indima ebalulekilei-carbon fibre cylinders ezinhlelweni ze-SCBA, ukuqinisekisa ukuphepha nokuthembeka kwazo kubaluleke kakhulu. Amazinga ahlukahlukene wamazwe ngamazwe nawezwe alawula ukukhiqizwa, ukuhlolwa, kanye nezitifiketi zala masilinda ukuze kuqinisekiswe ukuthi ahlangabezana nezidingo eziqinile zokuphepha.
I-DOT, NFPA, kanye nezitifiketi ze-EN
E-United States, uMnyango Wezokuthutha (DOT) ulawula ukuthuthwa nokusetshenziswa kwamasilinda anengcindezi ephezulu, okuhlanganisa nalawo asetshenziswa ezinhlelweni ze-SCBA. Amazinga we-DOT, achazwe kwimithethonqubo efana ne-49 CFR 180.205, acacisa ukwakheka, ukwakhiwa, kanye nezidingo zokuhlolai-carbon fibre cylinders ukuqinisekisa ukuthi bangakwazi ukumelana nezimo zomfutho ophezulu ngokuphepha.
I-National Fire Protection Association (NFPA) nayo idlala indima ebalulekile ekusunguleni izindinganiso zokuphepha zezinhlelo ze-SCBA ezisetshenziswa izicishamlilo nabaphenduli bezimo eziphuthumayo. Izinga le-NFPA 1981 lichaza izidingo zokusebenza zemishini ye-SCBA, kuhlanganisai-carbon fibre cylinders, ukuqinisekisa ukuthi bahlinzeka ngokuvikeleka okwanele nokusebenza emisebenzini yokucisha umlilo.
E-Europe, i-European Committee for Standardization (CEN) isungula amazinga afana ne-EN 12245, elawula ukuhlolwa nokuhlolwa kwezikhathi ezithile.isilinda segesi esiyinhlanganiselas. La mazinga aqinisekisa lokhoi-carbon fibre cylinders ukuhlangabezana nezidingo ezidingekayo zokuphepha nokusebenza ukuze zisetshenziswe ezimbonini ezihlukahlukene kanye nezicelo eziphuthumayo.
Izinqubo Zokuhlola Eziqinile
Ukuthobela la mazinga,i-carbon fibre cylinders ibhekana nemithethonqubo yokuhlola eqinile. Okunye ukuhlola okuyinhloko ukuhlola i-hydrostatic, lapho isilinda sigcwaliswa ngamanzi futhi sicindezelwe ngaphezu kwengcindezi evamile yokusebenza ukuze kuhlolwe ukuvuza, ukuwohloka, noma ubuthakathaka besakhiwo. Lokhu kuhlola kuvamise ukwenziwa njalo eminyakeni emihlanu ukuze kuqinisekiswe ubuqotho besilinda esikhathini esiphila kuso.
Ukuhlola okubukwayo nakho kubalulekile ukuze kutholwe umonakalo wangaphandle nowangaphakathi, njengokuqhekeka, ukugqwala, noma imihuzuko, okungafaka engozini ukuphepha kwesilinda. Lokhu kuhlola kuvame ukubandakanya ukusetshenziswa kwama-borescopes namanye amathuluzi akhethekile okuhlola indawo engaphakathi yesilinda.
Ngokungeziwe kulezi zivivinyo ezijwayelekile, abakhiqizi bangase benze ukuhlola okwengeziwe, okufana nokuhlolwa kokwehla nokuhlola ukuchayeka kwemvelo, ukuze bahlole ukusebenza kwesilinda ngaphansi kwezimo ezihlukahlukene. Ngokulandela lezi zinqubo zokuhlola eziqinile,i-carbon fibre cylinders zigunyazwe ukusetshenziswa okuphephile kumasistimu e-SCBA.
Izinzuzo zeI-Carbon Fiber Cylinders phezu kwamasilinda ensimbi ku-SCBA Applications
Ngenkathi amasilinda ensimbi endabuko asetshenziswe kabanzi ezinhlelweni ze-SCBA amashumi eminyaka,i-carbon fibre cylinderzinikeza izinzuzo ezimbalwa ezihlukene eziholele ekwandeni kwazo kokutholwa kuzo zonke izimboni ezihlukahlukene.
Isisindo Esinciphile
Inzuzo ebaluleke kakhulu yei-carbon fibre cylinders phezu kwamasilinda ensimbi yisisindo sawo esincishisiwe.I-carbon fibre cylinders ingaba lula ngo-50% kunamasilinda ensimbi, kwehlise ngokuphawulekayo umthwalo ophelele kumsebenzisi. Lokhu kuncipha kwesisindo kunenzuzo ikakhulukazi kubacimi bomlilo nabaphenduli bezimo eziphuthumayo, abavame ukusebenza ezindaweni ezinokucindezeleka okukhulu lapho ukufaneleka nokukhuthazela kubalulekile.
Amandla Akhulisiwe Nokuqina
I-carbon fibre cylinders iqhosha ngamandla aphakeme nokuqina uma kuqhathaniswa namasilinda ensimbi. Amandla aqinile wezinto ezihlanganisiwe azivumela ukuthi imelane nezilinganiso zengcindezi ephezulu, inikeze abasebenzisi umthamo womoya owengeziwe kanye nezikhathi zokusetshenziswa ezinwetshiwe. Ukwengeza, ukumelana kwe-carbon fiber ekugqwaleni nasekucekeleni phansi kwemvelo kuqinisekisa ukuthi amasilinda agcina ukusebenza kwawo ezimeni ezinzima.
Ukumelana Okuthuthukisiwe Ekucindezelekeni Kwemvelo
Ngokungafani namasilinda ensimbi, ajwayele ukugqwala nokugqwala ngokuhamba kwesikhathi,i-carbon fibre cylinders amelana kakhulu nezingcindezi zemvelo ezinjengomswakama, amakhemikhali, nemisebe ye-UV. Lokhu kumelana okuthuthukisiwe akugcini nje ngokunweba impilo yesilinda kodwa futhi kunciphisa ingcuphe yokwehluleka ngesikhathi sokusebenza okubucayi, okuthuthukisa ukuphepha komsebenzisi.
Izindleko-Ngempumelelo
Ngenkathi izindleko zokuqala zei-carbon fibre cylinders ingase ibe phezulu kunaleyo yamasilinda ensimbi, impilo yabo yesevisi enwetshiwe kanye nezidingo zokunakekelwa ezincishisiwe ngokuvamile zibenza babe yisixazululo esingabizi kakhulu ngokuhamba kwesikhathi. Isidingo sokushintshwa nokulungisa okumbalwa singaholela ekongeni kwezindleko ezinkulu zezinhlangano ezisebenzisa amasistimu e-SCBA.
Isiphetho
I-carbon fibre cylinderSesiphenduke isisekelo sezinhlelo ze-SCBA zesimanje, ezinikeza izinzuzo eziningi ngaphezu kwamasilinda ensimbi endabuko. Imvelo yazo engasindi, iqinile, futhi imelana nokugqwala ithuthukisa ukuphepha nokuhamba kwabasebenzisi ezindaweni eziyingozi, kuyilapho intuthuko kwezobuchwepheshe iqhubeka nokuthuthukisa ukusebenza kwabo. Ngokulandela izindinganiso zokuphepha eziqinile kanye nezinqubo zokuhlola,i-carbon fibre cylinders ukuqinisekisa ukwethembeka nokuvikelwa ezimeni ezibucayi. Njengoba izimboni kanye nezinsizakalo eziphuthumayo ziqhubeka nokubeka phambili ukuphepha nokusebenza kahle, ukwamukelwa kwei-carbon fibre cylinders ezinhlelweni ze-SCBA zihlelelwe ukuthi zikhule, ziqinise indima yazo njengengxenye ebalulekile yezinto zokusebenza ezisindisa ukuphila.
