Hlobo luni lwe-SCBA Abacimi bomlilo abalusebenzisayo?

Izicishamlilo zithembele ku-Self-Contained Breathing Apparatus (SCBA) ukuze zizivikele kumagesi ayingozi, intuthu, nezindawo ezingenawo umoya-mpilo phakathi nemisebenzi yokucisha umlilo. I-SCBA iwucezu olubalulekile lwemishini yokuzivikela yomuntu siqu, evumela izicishamlilo ukuthi ziphefumule ngokuphepha ngenkathi zibhekana nezimo eziyingozi. Ama-SCBA anamuhla asetshenziswa izicishamlilo athuthuke kakhulu, ahlanganisa izingxenye ezihlukahlukene ukuze kuqinisekiswe ukuphepha, induduzo, nokuqina. Enye yezinto ezibaluleke kakhulu zezinhlelo ze-SCBA zesimanje ukusetshenziswa kweIsilinda esiyinhlanganisela ye-carbon fibers, enikeza izinzuzo ezibalulekile ngokwesisindo, ukuqina, kanye nokusebenziseka kalula.

Lesi sihloko sidingida ezinhlotsheni zezicishamlilo ze-SCBAs ezisetshenziswayo, sigxile ikakhulukazi endimeni yeIsilinda esiyinhlanganisela ye-carbon fibers nokuthi kungani sebeba yisinqumo esijwayelekile egiyeni lokucisha umlilo.

Izingxenye ze-SCBA Nezinhlobo

Uhlelo lwe-SCBA olusetshenziswa izicishamlilo luqukethe izingxenye ezimbalwa ezibalulekile:

1. I-Air Cylinder:Iisilinda somoyaingxenye ye-SCBA egcina umoya ophefumulayo ngaphansi kwengcindezi ephezulu, okuvumela izicishamlilo ukuba ziphefumule ezindaweni eziyingozi.
2. Isilawuli Sokucindezela kanye namaHoses:Lezi zingxenye zinciphisa umoya onomfutho ophezulu ogcinwe kusilinda ube sezingeni eliphefumulayo, obese ulethwa kusicishamlilo ngemaski.
3. Imaski yobuso (i-Facepiece):Imaski yobuso iyisembozo esivaliwe esivikela ubuso besicishamlilo ngenkathi sinikeza umoya. Idizayinelwe ukuhlinzeka ngokuvalwa okuqinile ukuvimbela intuthu namagesi ayingozi ukuthi angangeni kumaski.
4. I-Harness ne-Backplate:Isistimu yamahhanisi ivikela i-SCBA emzimbeni wesicishamlilo, isabalalisa isisindo sesilinda futhi ivumela umsebenzisi ukuthi ahambe ngokukhululeka.
5. Ama-alamu namasistimu okuqapha:Ama-SCBA esimanje ngokuvamile ahlanganisa amasistimu e-alamu ahlanganisiwe axwayisa isicishamlilo uma umoya wabo uphansi noma uma uhlelo luhlangabezana nanoma yikuphi ukungasebenzi kahle.

Izinhlobo zamasilinda omoya ku-SCBA yokucisha umlilo

Isilinda somoya ngokungangabazeki siyingxenye ebaluleke kakhulu ye-SCBA, njengoba inikeza ngokuqondile umoya ophefumulayo. Amasilinda ahlukaniswa ikakhulukazi ngezinto ezenziwe ngazo, ngensimbi, i-aluminium, kanyeIsilinda esiyinhlanganisela ye-carbon fibers ukuba okuvame kakhulu. Ezicelweni zokucisha umlilo,Isilinda esiyinhlanganisela ye-carbon fibers zivame ukuthandwa ngenxa yezinzuzo zazo eziningi.

Amasilinda ensimbi

Amasilinda ensimbi ayinketho yendabuko yama-SCBA futhi aziwa ngokuqina kwawo nekhono lokumelana nezingcindezi eziphezulu. Kodwa-ke, amasilinda ensimbi asindayo, okwenza angalungeli kakhulu ekucimeni umlilo. Isisindo se-cylinder yensimbi singenza kube nzima ukuthi izicishamlilo zihambe ngokushesha nangempumelelo, ikakhulukazi ezindaweni ezinokucindezeleka okuphezulu njengezakhiwo ezivuthayo.

Aluminium Cylinders

Amasilinda e-aluminium alula kunensimbi kodwa asasinda kunamasilinda ayinhlanganisela ye-carbon fibre. Banikeza ibhalansi enhle phakathi kwezindleko nesisindo kodwa bangase banganikezi izinga elifanayo lokunethezeka noma ukuhamba kalula njengamasilinda e-carbon fiber emisebenzini enwetshiwe yokucisha umlilo.

I-Carbon Fiber Composite Cylinders

Isilinda esiyinhlanganisela ye-carbon fibres avele njengokukhetha okuthandwayo kwezinhlelo zesimanje ze-SCBA ezisetshenziswa izicishamlilo. Lawa masilinda enziwa ngokusonga ilineni elingaphakathi (ngokuvamile elenziwe nge-aluminiyamu noma ipulasitiki) elinezingqimba ze-carbon fiber, into engasindi futhi eqine ngokwedlulele. Umphumela uba isilinda esingabamba umoya lapho kunengcindezi ephezulu kakhulu kuyilapho ilula kakhulu kunezinye izinto zensimbi noma ze-aluminium.

Izinzuzo zeI-Carbon Fiber Composite Cylinders:

1. Okungasindi: Isilinda esiyinhlanganisela ye-carbon fibres alula kakhulu kunawo womabili amasilinda ensimbi ne-aluminium. Lokhu kuncipha kwesisindo kungenza umehluko omkhulu ngesikhathi sokusebenza isikhathi eside sokucima umlilo, lapho ikhono lokuhamba ngokushesha nangempumelelo libalulekile.
2. Ukuqina:Naphezu kokuba nesisindo esincane,Isilinda esiyinhlanganisela ye-carbon fibers ziqine ngendlela emangalisayo futhi zihlala isikhathi eside. Bangakwazi ukumelana nezingcindezi eziphakeme futhi bamelane nokulimala okuvela emithelela, okubenza bafaneleke kahle izimo ezinzima abacishimlilo abavame ukubhekana nazo.
3. Ukumelana Nokugqwala:Ngokungafani nensimbi,i-carbon fiber cylinders musa ukugqwala, okuthuthukisa ukuphila kwabo isikhathi eside futhi kunciphisa isidingo ukugcinwa njalo.
4. Impilo Yesevisi Ende:Ngokuya ngohlobo lwesilinda,Isilinda esiyinhlanganisela ye-carbon fiberbaphile impilo yesevisi efinyelela eminyakeni eyi-15 (Uhlobo 3), kuyilapho ezinye zintshaThayipha amasilinda angu-4 ane-PET liners ingase ingabi namkhawulo wempilo yesevisi ngaphansi kwezimo ezithile. Lokhu kubenza babe utshalomali olungabizi kakhulu esikhathini eside.
5. Umthamo Womoya Ophakeme:Ngenxa yekhono labo lokubamba umoya ezingcindezini eziphakeme,Isilinda esiyinhlanganisela ye-carbon fibers vumela abacimi bomlilo ukuthi baphathe umoya omningi ephaketheni elilula. Lokhu kusho ukuthi bangahlala ezindaweni eziyingozi isikhathi eside ngaphandle kokudinga ukushintsha amasilinda.

KanjaniI-Carbon Fiber Cylinders Zuza izicishamlilo

Izicishamlilo kudingeka zihambe ngokushesha futhi zisebenze ngaphansi kwezimo ezishubile, futhi izinto zokusebenza eziziphethe akufanele zibabambezele.Isilinda esiyinhlanganisela ye-carbon fibres ziyisixazululo sale nselele, enikeza izinzuzo ezibalulekile ezithuthukisa ngokuqondile ukusebenza kahle kwabacimi bomlilo emsebenzini.

Ukuhamba Okuthuthukisiwe

Isisindo esincane sei-carbon fiber cylinders kusho ukuthi abacimi bomlilo abathwele kanzima ngamagiya abo. Amasilinda ensimbi endabuko angaba nesisindo esingaphezu kwamakhilogremu angu-25, okwengeza ubunzima kubacishi bomlilo asebevele begqoke izingubo zokuzivikela ezisindayo futhi bephethe amathuluzi engeziwe.I-carbon fibre cylinders, ngokuphambene, ingaba nesisindo esingaphansi kwesigamu salelo nani. Lokhu kwehliswa kwesisindo kusiza abacimi bomlilo ukuba balondoloze ukushesha nesivinini, okubalulekile lapho bezulazula emabhilidini agcwele intuthu noma ukugibela izitebhisi ngesikhathi sesimo esiphuthumayo.

Ukunikezwa Komoya Okukhulisiwe Kokusebenza Okude

Enye inzuzo yeIsilinda esiyinhlanganisela ye-carbon fibers amandla abo okugcina umoya ezicindezelweni eziphakeme—imvamisa engu-4,500 psi (amaphawundi ngeyintshi yesikwele) noma ngaphezulu, uma kuqhathaniswa nezingcindezi eziphansi kumasilinda ensimbi noma e-aluminium. Lo mthamo ophakeme uvumela izicishamlilo ukuthi zithwale umoya omningi owuphefumulayo ngaphandle kokukhulisa usayizi noma isisindo sesilinda, okubenza bakwazi ukuhlala emsebenzini isikhathi eside ngaphandle kokudinga ukuhlehla ukuze bashintshe isilinda.

Ukuqina Ezimweni Eziqinile

Ukucisha umlilo kudingekile ngokomzimba futhi kwenzeka ezindaweni eziyingozi lapho okokusebenza kuchayeke kumazinga okushisa aphezulu, imfucumfucu ebukhali, nokuphathwa kabi.Isilinda esiyinhlanganisela ye-carbon fibres zenzelwe ukumelana nalezi zinselele. Ukugoqa kwe-carbon fibre kunikeza ukuvikeleka okwengeziwe emithelela kanye namanye amandla angaphandle, kunciphisa amathuba okulimala kanye nokwenza ngcono ukwethembeka okuphelele kohlelo lwe-SCBA.

Isondlo kanye Nempilo Yesevisi

I-carbon fibre cylinders, ikakhulukaziThayipha isilinda 3s enamalayini we-aluminium, ngokuvamile anempilo yesevisi yeminyaka eyi-15. Ngalesi sikhathi, kufanele zihlolwe njalo futhi zihlolwe ukuze kuqinisekiswe ukuphepha nokusebenza kwazo.Thayipha amasilinda angu-4, asebenzisa ulayini wepulasitiki (PET)., ingase ibe nokuphila okungenamkhawulo kuye ngokusetshenziswa nokunakekelwa. Le mpilo yesevisi eyandisiwe ingenye inzuzo eyenzai-carbon fiber cylindersa choice esiwusizo iminyango izicishamlilo.

Isiphetho

Abacimi bomlilo babhekana nezingozi ezisongela ukuphila phakathi nomsebenzi wabo, futhi bancike ezintweni zabo ukuze bazigcine bephephile. Amasistimu e-SCBA ayingxenye ebalulekile yegiya lawo lokuvikela, futhi isilinda somoya sidlala indima ebalulekile ekuqinisekiseni ukutholakala komoya okuzinzile ezindaweni eziyingozi.Isilinda esiyinhlanganisela ye-carbon fibres sebeyinketho ephezulu yezinhlelo ze-SCBA ekucimeni umlilo ngenxa yokwakheka kwazo okungasindi, okuhlala isikhathi eside, kanye nomthamo omkhulu. Lezi zisilinda zinikeza izinzuzo ezibalulekile ngaphezu kwezinketho zensimbi zendabuko ne-aluminium, zithuthukisa ukuhamba, ukunethezeka, nokusebenza kahle kwezicishamlilo. Njengoba ubuchwepheshe be-SCBA buqhubeka nokuvela,i-carbon fiber cylinders izohlala iyingxenye ebalulekile ekuthuthukiseni ukuphepha nokusebenza kwezicishamlilo.
