Izicishamlilo zibhekana nezimo eziyingozi ngendlela emangalisayo, futhi enye yezinto zokusebenza ezibucayi kakhulu eziziphetheyo i-Self-Contained Breathing Apparatus (SCBA), ehlanganisa ithangi lomoya. Lawa amathangi omoya ahlinzeka komoya ophefumulayo ezindaweni ezigcwele intuthu, intuthu enobuthi, noma amazinga omoya-mpilo aphansi. Ekucimeni umlilo kwesimanje,isilinda esiyinhlanganisela ye-carbon fibres zisetshenziswa kakhulu ezinhlelweni ze-SCBA ngoba zinikeza izinzuzo ezimbalwa kuzinto zendabuko. Esinye sezici ezibaluleke kakhulu uma kuziwa emathangeni omoya wezicishamlilo ukucindezela abangakubamba, njengoba lokhu kunquma ukuthi ukunikezwa komoya kuzohlala isikhathi esingakanani ezimeni eziyingozi.
Iyini Ingcindezi Yethangi Lomoya Lokucisha Umlilo?
Ingcindezi emathangini omoya wezicishamlilo ngokuvamile iphezulu kakhulu, isukela ku-2,216 psi (amaphawundi ngeyintshi yesikwele) ukuya ku-4,500 psi. Lawa mathangi aklanyelwe ukugcina umoya ocindezelweyo, hhayi umoya-mpilo ohlanzekile, ovumela izicishamlilo ukuba ziphefumule ngokujwayelekile ngisho nasezindaweni ezigcwele intuthu. Ukucindezela okuphezulu kuqinisekisa ukuthi umthamo omkhulu womoya ungagcinwa ku-cylinder encane futhi ephathekayo, ebalulekile ekuhambeni nokusebenza kahle okudingekayo ezimweni eziphuthumayo.
Amathangi omoya wezicishamlilo eza ngosayizi abahlukene, kodwa ngokuvamile, aklanyelwe ukuhlinzeka phakathi kwemizuzu engama-30 nengama-60 yomoya, kuye ngosayizi wesilinda kanye nezinga lokucindezela. Isilinda semizuzu engu-30, isibonelo, ngokuvamile sibamba umoya ku-4,500 psi.
Iqhaza likaI-Carbon Fiber Composite Cylinders ku-SCBA Systems
Ngokwesiko, amathangi omoya abacishi bomlilo ayenziwe ngensimbi noma nge-aluminium, kodwa lezi zinto zazinezinkinga ezinkulu, ikakhulukazi ngokwesisindo. Isilinda sensimbi singaba nzima kakhulu, okwenza kube nzima ukuthi izicishamlilo zihambe ngokushesha futhi ziqondise ezindaweni eziqinile noma eziyingozi. Amathangi e-Aluminium alula kunensimbi kodwa asasinda ngokuqhathaniswa nezidingo zokucisha umlilo.
Faka iisilinda esiyinhlanganisela ye-carbon fibre. Lawa masilinda manje aseyinketho ekhethwayo eminyangweni eminingi yezicishamlilo emhlabeni jikelele. Yenziwe ngokusonga i-polymer liner engasindi enezendlalelo ze-carbon fiber, lawa masilinda anikeza izinzuzo ezimbalwa ezibalulekile zezinhlelo ze-SCBA.
Izinzuzo Eziyinhloko zeI-Carbon Fiber Composite Cylinders
- Isisindo EsilulaEnye yezinzuzo ezibaluleke kakhulu zeisilinda esiyinhlanganisela ye-carbon fibres isisindo sabo esiphansi kakhulu. Izicishamlilo sezivele ziphethe inqwaba yezimpahla, okuhlanganisa izingubo zokuzivikela, izigqoko zokuzivikela, amathuluzi, nokunye. Ithangi lomoya lingenye yezinto ezisinda kakhulu kukhithi yabo, ngakho-ke noma yikuphi ukuncipha kwesisindo kubaluleke kakhulu.Isilinda esiyinhlanganisela ye-carbon fibreInesisindo esingaphansi kakhulu kunensimbi noma i-aluminium, okwenza kube lula ukuthi izicishamlilo zihambe ngokushesha nangempumelelo ezindaweni eziyingozi.
- High Pressure HandlingIsilinda esiyinhlanganisela ye-carbon fibres ziyakwazi ukumelana nezingcindezi eziphezulu kakhulu, okuyisici esibalulekile ezinhlelweni ze-SCBA. Njengoba kushiwo, amathangi amaningi omoya wokucima umlilo acindezelwa cishe ku-4,500 psi, futhii-carbon fibre cylinders zakhelwe ukuphatha ngokuphephile lezi zingcindezi. Lo mthamo wengcindezi ephezulu ubavumela ukuthi bagcine umoya omningi ngevolumu encane, okwandisa isikhathi lapho isicishamlilo singasebenza ngaphambi kokudinga ukushintsha amathangi noma ukushiya indawo eyingozi.
- UkuqinaNaphezu kokuba nesisindo esincane,isilinda esiyinhlanganisela ye-carbon fibres ziqine ngendlela emangalisayo. Zenzelwe ukubekezelela ukuphathwa kabi, umthelela omkhulu, nezimo ezinzima. Ukucima umlilo kuwumsebenzi onzima ngokomzimba, futhi amathangi omoya angachayeka ekushiseni okukhulu, imfucumfucu ewayo, nezinye izingozi. Ukuqina kwe-carbon fiber kuqinisekisa ukuthi isilinda sizohlala sinjalo futhi siphephile ngaphansi kwalezi zimo, okuhlinzeka umthombo onokwethenjelwa womoya wesicishi-mlilo.
- Ukumelana NokugqwalaAmasilinda ensimbi endabuko ajwayele ukugqwala, ikakhulukazi uma echayeke kumswakama noma amakhemikhali abacimi bomlilo abangase bahlangane nawo emsebenzini wabo.Isilinda esiyinhlanganisela ye-carbon fibres, ngakolunye uhlangothi, amelana kakhulu nokugqwala. Lokhu akugcini nje ngokunweba isikhathi sokuphila samasilinda kodwa futhi kuwenza aphephe ukusetshenziswa ezindaweni eziningi.
Ingcindezi Nobude Besikhathi: Ithangi Lomoya Lokucisha Umlilo Lihlala Isikhathi Engakanani?
Inani lesikhathi isicishamlilo esingasichitha sisebenzisa ithangi lomoya elilodwa sincike kukho kokubili ubukhulu besilinda kanye nokucindezela esikuphethe. Amasilinda amaningi e-SCBA afika ngokuhlukahluka kwemizuzu engama-30 noma engama-60. Nokho, lezi zikhathi ziyalinganiselwa futhi zisekelwe emazingeni amaphakathi okuphefumula.
Umcishi-mlilo osebenza kanzima endaweni enengcindezi enkulu, njengokucisha umlilo noma ukutakula othile, angase aphefumule kakhulu, okunganciphisa isikhathi sangempela esizohlala ithangi. Ukwengeza, isilinda esiyimizuzu engama-60 empeleni asihlinzeki ngemizuzu engu-60 yomoya uma umsebenzisi ephefumula ngokushesha ngenxa yokuzikhandla noma ingcindezi.
Ake sihlolisise ukuthi ukucindezela kusilinda kuhlobana kanjani nokunikezwa komoya. Isilinda se-SCBA esijwayelekile semizuzu engama-30 ngokuvamile sibamba amalitha omoya acishe abe ngu-1,200 uma ucindezelwa ukuya ku-4,500 psi. Ingcindezi iyona ecindezela lowo mthamo omkhulu womoya ube usilinda omncane ngokwanele ukuthi ungathwalwa emhlane wesicishamlilo.
I-Carbon Fiber Composite Cylinders kanye Nokuphepha
Ukuphepha kuhlala kuyinto ehamba phambili uma kuziwa ezintweni ezisetshenziswa izicishamlilo.Isilinda esiyinhlanganisela ye-carbon fibres bahlolwe kanzima ukuze kuqinisekiswe ukuthi bayakwazi ukumelana nezingcindezi eziphezulu kanye nezimo ezimbi kakhulu. Inqubo yokukhiqiza ibandakanya ubunjiniyela obunembayo ukuze bakhe isilinda esiqinile nesilula. Ukwengeza, la masilinda angaphansi kokuhlolwa kwe-hydrostatic, inqubo lapho isilinda sigcwaliswa ngamanzi futhi sicindezelwe ukuze kuqinisekiswe ukuthi singakwazi ukumelana nezingcindezi zokusebenza ezidingekayo ngaphandle kokuvuza noma ukwehluleka.
Izakhiwo ezivimbela amalangabi zeisilinda esiyinhlanganisela ye-carbon fibrefuthi engeza kuphrofayela yabo yokuphepha. Lapho kushisa umlilo, kubalulekile ukuthi ithangi lomoya lingabi yingozi ngokwalo. Lawa masilinda aklanyelwe ukumelana namazinga okushisa aphezulu futhi avikele ukutholakala komoya ngaphakathi.
Isiphetho
Amathangi omoya wezicishamlilo abalulekile ekuhlinzekeni umoya ophefumulayo ezimweni ezisongela ukuphila. Amandla okucindezela okukhulu kwalawa mathangi, ngokuvamile afinyelela ku-4,500 psi, aqinisekisa ukuthi izicishamlilo zifinyelela ekunikezeni umoya okwanele ngesikhathi sezimo eziphuthumayo. Ukwethulwa kweisilinda esiyinhlanganisela ye-carbon fibres iguqule indlela la mathangi asetshenziswa ngayo, enikeza izinzuzo ezibalulekile ngokwesisindo, ukuqina, nokuphepha.
Isilinda esiyinhlanganisela ye-carbon fibres ivumela izicishamlilo ukuthi zihambe ngokukhululeka futhi zihlale ezindaweni eziyingozi isikhathi eside ngaphandle kokudinga ukucisha amathangi njalo. Ikhono labo lokumelana nokucindezela okuphezulu kanye nezimo ezimbi kakhulu kubenza babe yisinqumo esifanele sokucisha umlilo kwanamuhla. Ngokuthuthuka okuqhubekayo kwesayensi yezinto zokwakha, singalindela ukuthuthuka okwengeziwe kubuchwepheshe be-SCBA esikhathini esizayo, sithuthukise ngokwengeziwe ukuphepha nokusebenza kahle kwemisebenzi yokucisha umlilo.
