I-Self-Contained Breathing Apparatus (SCBA) iyithuluzi lokuphepha elibalulekile elisetshenziswa izicishamlilo, abasebenzi bezimboni, nabaphenduli bezimo eziphuthumayo ukuze bazivikele ezindaweni eziyingozi. Ingxenye eyinhloko yanoma iyiphi isistimu ye-SCBA ithangi lomoya, eligcina umoya ocindezelwe umsebenzisi awuphefumulayo. Ngokuhamba kweminyaka, ukuthuthuka kwezobuchwepheshe bezinto ezibonakalayo kuye kwaholela ekusetshenzisweni okubanzi kweIsilinda esiyinhlanganisela ye-carbon fibers kumasistimu e-SCBA. Lawa mathangi aziwa ngokuba angasindi, aqinile futhi aqinile. Nokho, njengazo zonke izinto zokusebenza, zinesikhathi sokuphila esilinganiselwe. Lesi sihloko sizohlola ukuthi isikhathi eside kangakananicarbon fibre SCBA tanks zilungele, zigxile ezinhlotsheni ezahlukene zei-carbon fiber cylinders, kanye nezici ezithinta ukuphila kwabo isikhathi eside.
UkuqondaI-Carbon Fiber SCBA Tanks
Ngaphambi kokutshuza esikhathini sokuphila kwala mathangi, kubalulekile ukuqonda ukuthi ayini nokuthi kungani i-carbon fiber isetshenziswa ekwakhiweni kwawo.Isilinda esiyinhlanganisela ye-carbon fibres enziwa ngokusonga i-carbon fiber impahla ezungeze umugqa, obamba umoya ocindezelwe. Ukusetshenziswa kwe-carbon fiber kunikeza lamathangi isilinganiso esiphezulu samandla nesisindo, okusho ukuthi alula kakhulu kunensimbi evamile noma amasilinda e-aluminium kodwa aqinile nje, uma engaqinile.
Kunezinhlobo ezimbili eziyinhloko zecarbon fibre SCBA tanks: Uhlobo 3futhiUhlobo 4. Uhlobo ngalunye lunezindlela ezahlukene zokwakha nezici ezithonya impilo yalo yesevisi.
Thayipha 3 Carbon Fiber SCBA Tanks: Iminyaka engu-15 yokuphila
Thayipha isilinda se-carbon fibre 3s banomugqa we-aluminium osongwe nge-carbon fiber. I-aluminium liner isebenza njengomgogodla obamba umoya ocindezelwe, kuyilapho ukugoqa kwe-carbon fiber kunikeza amandla engeziwe nokuqina.
Lawa amathangi asetshenziswa kakhulu ezinhlelweni ze-SCBA ngoba anikeza ibhalansi enhle phakathi kwesisindo, amandla, kanye nezindleko. Nokho, banayo isikhathi sokuphila esichaziwe. Ngokuvumelana nezindinganiso zezimboni,Thayipha ithangi le-3 carbon fibre SCBAs ngokuvamile zilinganiselwe iminyaka engu-15 yokuphila kwesevisi. Ngemuva kweminyaka engu-15, amathangi kufanele akhishwe emsebenzini, kungakhathaliseki ukuthi isimo sawo sinjani, ngoba izinto ezisetshenziswayo zingase ziwohloke ngokuhamba kwesikhathi, zenze zingavikeleki kakhulu ukuzisebenzisa.
Thayipha 4 I-Carbon Fiber SCBA Tanks: Akukho Ukuphila Okukhawulelwe (NLL)
Thayipha isilinda se-carbon fiber 4s zihluke kuUhlobo 3ngokuthi basebenzisa i-non-metallic liner, ngokuvamile eyenziwe ngezinto zepulasitiki ezifana ne-PET (Polyethylene Terephthalate). Le liner bese isongwe nge-carbon fiber, njengeThayipha ithangi elingu-3s. Inzuzo eyinhloko yeThayipha ithangi elingu-4s wukuthi alula ngisho nangaphezuThayipha ithangi elingu-3s, okwenza kube lula ukuthwala nokusebenzisa ezimeni ezinzima.
Omunye umehluko obaluleke kakhulu phakathiUhlobo 3futhiThayipha isilinda 4s yilokhoThayipha isilinda 4s kungenzeka ingabi nesikhathi sokuphila esinqunyelwe (NLL). Lokhu kusho ukuthi, ngokunakekelwa okufanele, ukulungiswa, nokuhlolwa okuvamile, lamathangi angasetshenziswa unomphela. Nokho, kubalulekile ukuqaphela lokho nakubaThayipha isilinda 4s zikalwe njenge-NLL, zisadinga ukuhlolwa njalo kanye nokuhlolwa kwe-hydrostatic ukuze kuqinisekiswe ukuthi zihlala ziphephile ukuthi zingasetshenziswa.
Izinto Ezithinta Isikhathi Sokuphila SeI-Carbon Fiber SCBA Tanks
Ngenkathi ubude bempilo obulinganiselwe bokuthiI-SCBA tanks inikeza umhlahlandlela omuhle wokuthi kufanele zishintshwe nini, izici ezimbalwa zingathinta ubude bempilo bangempela be-ai-carbon fiber cylinder:
- Ukusebenzisa Imvamisa: Amathangi asetshenziswa njalo azoguga kakhulu kunalawo asetshenziswa kancane. Lokhu kungathinta ubuqotho bethangi futhi kunciphise ukuphila kwalo.
- Izimo Zemvelo: Ukuchayeka emazingeni okushisa adlulele, umswakama, noma amakhemikhali abolayo angehlisa isithunziI-carbon fiber tankngokushesha okukhulu. Ukugcinwa nokuphatha ngendlela efanele kubalulekile ukuze kugcinwe isikhathi eside se-cylinder.
- Isondlo kanye Nokuhlolwa: Ukuhlolwa njalo nokunakekelwa kubalulekile ukuze kuqinisekiswe ukuphepha nokuphila isikhathi esideI-SCBA tanks. Ukuhlolwa kwe-Hydrostatic, okubandakanya ukucindezela ithangi ngamanzi ukuze kuhlolwe ukuvuza noma ubuthakathaka, kuyadingeka njalo eminyakeni emi-3 kuya kwemi-5, kuye ngemithethonqubo. Amathangi aphumelele lezi zivivinyo angaqhubeka nokusetshenziswa aze afinyelele ubude bawo bokuphila obulinganiselwe (iminyaka eyi-15Uhlobo 3noma i-NLL yeUhlobo 4).
- Ukulimala Emzimbeni: Noma imuphi umthelela noma umonakalo ethangini, njengokuliwisa noma ukulibeka ezintweni ezicijile, kungaphazamisa ubuqotho balo besakhiwo. Ngisho nokulimala okuncane kungaholela ezingozini ezinkulu zokuphepha, ngakho-ke kubalulekile ukuhlola amathangi njalo ukuze uthole noma yiziphi izimpawu zokulimala ngokomzimba.
Amathiphu Esondlo Okwandisa Ubude Besikhathi Sokuphila KweI-SCBA Tanks
Ukuze ukwandise ubude bempilo yakhoI-SCBA tanks, kubalulekile ukulandela izinqubo ezingcono kakhulu zokunakekela nokunakekela:
- Gcina Kahle: Gcina njaloI-SCBA tanks endaweni epholile, eyomile ekude nelanga eliqondile namakhemikhali anokhahlo. Gwema ukunqwabelanisa phezu kwamanye noma ukuwagcina ngendlela engaholela emazingeni noma omunye umonakalo.
- Phatha Ngokunakekela: Uma usebenzisaI-SCBA tanks, ziphathe ngokucophelela ukuze zigweme ukuwa noma imithelela. Sebenzisa impahla yokugxumeka efanele ezimotweni namaracks okugcina amathangi ephephile.
- Ukuhlola Okuvamile: Yenza ukuhlola okuvamile kwethangi ukuze uthole noma yiziphi izimpawu zokuguga, ukonakala, noma ukugqwala. Uma ubona noma yiziphi izinkinga, cela ithangi lihlolwe uchwepheshe ngaphambi kokulisebenzisa futhi.
- Ukuhlolwa kwe-Hydrostatic: Namathela kushejuli edingekayo yokuhlolwa kwe-hydrostatic. Lokhu kuhlola kubalulekile ukuze kuqinisekiswe ukuphepha kwethangi nokuhambisana nezindinganiso zomkhakha.
- Umhlalaphansi Wamathangi: NgobaThayipha isilinda 3s, qiniseka ukuhoxisa ithangi ngemva kweminyaka engu-15 yesevisi. NgobaThayipha isilinda 4s, nakuba zilinganiselwe njenge-NLL, kufanele uziyeke uma zibonisa izimpawu zokuguga noma zehluleka noma yikuphi ukuhlolwa kokuphepha.
Isiphetho
Ithangi le-Carbon fiber SCBAs ziyingxenye ebalulekile yempahla yokuphepha esetshenziswa ezindaweni eziyingozi. NgenkathiThayipha ithangi le-carbon fiber 3s abe nesikhathi esichaziwe seminyaka eyi-15,Thayipha ithangi elingu-4s ngaphandle komkhawulo wesikhathi sokuphila kungasetshenziswa unomphela ngokunakekela nokunakekelwa okufanele. Ukuhlolwa okuvamile, ukuphathwa ngendlela efanele, kanye nokuhambisana neshejuli yokuhlola kuyisihluthulelo sokuqinisekisa ukuphepha nokuphila isikhathi eside kwalawa mathangi. Ngokulandela izinqubo ezihamba phambili, abasebenzisi bangaqinisekisa ukuthi amasistimu abo e-SCBA ahlala ethembekile futhi esebenza kahle, ehlinzeka ngokuvikeleka okubalulekile ezindaweni lapho umoya ohlanzekile ubalulekile.
