IsiXhobo sokuPhuma ngokuNgxamisekileyo (EEBD) sisixhobo esibalulekileyo sokhuseleko esenzelwe ukusetyenziswa kwindawo apho i-atmosfera ibe yingozi, ibeka umngcipheko okhawulezileyo wobomi okanye impilo. Ezi zixhobo ziqhele ukusetyenziswa kwiimeko apho kukho ukukhutshwa ngokukhawuleza kweegesi ezinetyhefu, umsi, okanye ukusilela kweoksijini, ukunika umntu onxibileyo umoya owaneleyo wokuphefumla ukubaleka ngokukhuselekileyo kwindawo eyingozi.
Ii-EEBD zifumaneka kumashishini ahlukeneyo, kubandakanywa ukuthutha, imigodi, ukuvelisa, kunye neenkonzo eziphuthumayo, kwaye zenzelwe ukubonelela ngokhuseleko lwexesha elifutshane kubantu ababaleka kwindawo enobungozi kunokuba basebenzise ixesha elide. Nangona kungenzelwanga ukucinywa komlilo okanye imisebenzi yokuhlangula, ii-EEBD zisisixhobo esibalulekileyo sokhuseleko esinokuthintela ukufuthanisela okanye ukutyhefa xa isibini ngasinye sibala. Elona candelo lee-EEBDs zangoku licarbon fiber composite cylinder, edlala indima ebalulekileyo ekwenzeni izixhobo zibe khaphukhaphu, zomelele, kwaye zithembeke kwiimeko zonxunguphalo.
Isebenza njani iEEBD
I-EEBD ngokusisiseko sisixhobo sokuphefumla esibumbeneyo esibonelela umsebenzisi ngesibonelelo somoya ophefumlayo okanye ioksijini kangangexesha elithile, ngokuqhelekileyo phakathi kwemizuzu emi-5 ukuya kweli-15, ngokuxhomekeke kwimodeli. Isixhobo silula ukusebenza, naphantsi koxinzelelo, kwaye sihlala sisebenza ngokutsala ithebhu okanye ukuvula isitya. Nje ukuba isebenze, umoya okanye unikezelo lweoksijini luqala ukugeleza lusiya kumsebenzisi, nokuba kungemaski yobuso okanye isigqubuthelo somlomo kunye nenkqubo yekliphu yempumlo, ukwenza isitywina esibakhusela ekusezeleni iigesi eziyingozi okanye umoya ongenawo ioksijini.
Amacandelo e-EEBD
Amacandelo asisiseko eEEBD abandakanya:
- Isilinda sokuphefumla: Le cylinder igcina umoya oxinanisiweyo okanye ioksijini leyo umsebenzisi aya kuyiphefumla ngexesha lokubaleka. Ii-EEBDs zanamhlanje ziya zisanda kusebenzisa ciarbon fibre composite cylinders ngenxa yobunzima babo kunye namandla.
- Ulawulo loxinzelelo: Umlawuli ulawula ukuhamba komoya okanye i-oksijini ukusuka kwi-cylinder, ukuqinisekisa ukuba umsebenzisi ufumana unikezelo oluzinzileyo lomoya ophefumulayo.
- Imaski yobuso okanye ihood: Imaski okanye i-hood igubungela ubuso bomsebenzisi, inika isitywina esigcina iigesi ezinobungozi ngelixa livumela ukuba baphefumle emoyeni okanye i-oksijini enikezelwa yi-EEBD.
- Ukubopha okanye umtya: Oku kukhusela isixhobo kumsebenzisi, kubavumela ukuba bahambe ngokukhululekile ngelixa begqoke i-EEBD.
- Inkqubo yeAlam: Ezinye ii-EEBD zixhotyiswe nge-alamu ekhalayo xa ukunikezelwa komoya kuphantsi, kubangela ukuba umsebenzisi akhawuleze ukubaleka.
I-Carbon Fiber Composite Cylinders kwii-EEBDs
Enye yezona zinto zibalulekileyo ze-EEBD yi-cylinder yokuphefumula, kwaye izinto ezisetyenziselwa le cylinder zidlala indima enkulu ekusebenzeni ngokubanzi kwesixhobo. Kwii-EEBD ezininzi zanamhlanje,carbon fiber composite cylinders zisetyenziswa ngenxa yeepropati zabo eziphezulu xa kuthelekiswa nezinto zemveli njengentsimbi okanye i-aluminium.
Uyilo oluKhala
Enye yeenzuzo ezibalulekileyo zecarbon fiber composite cylinders luyilo lwabo olukhaphukhaphu. Kwiimeko ezingxamisekileyo, nganye yesibini ibala, kunye ne-EEBD elula ivumela umsebenzisi ukuba ahambe ngokukhawuleza kwaye akhululeke ngakumbi. Iicomposites zeCarbon fibre zikhaphukhaphu kakhulu kunentsimbi kunye ne-aluminiyam ngelixa zisenamandla ngokwaneleyo ukuba ziqulathe umoya oxinanisiweyo okanye ioksijini kuxinzelelo oluphezulu. Oku kunciphisa ubunzima kunceda umsebenzisi ukuba aphephe ukudinwa, okwenza kube lula ukuphatha isixhobo ngexesha lokubaleka.
Ukuzinza okuphezulu kunye namandla
Ikhabhon fiber composite cylinders azikhaphukhaphu kuphela kodwa zomelele ngokugqithisileyo kwaye zomelele. Ziyakwazi ukumelana noxinzelelo oluphezulu olufunekayo ukugcina umoya owaneleyo wokuphepha ngokukhuselekileyo, kwaye zixhathisa umonakalo ovela kwimpembelelo, i-corrosion, kunye nokugqoka. Oku komelela kubalulekile kwiimeko zonxunguphalo apho isixhobo sinokuphathwa rhabaxa, amaqondo obushushu aphezulu, okanye sichanabeke kwiikhemikhali eziyingozi. Amandla e-carbon fiber avumela i-cylinder ukuba ihlale ihambelana kwaye isebenze, iqinisekisa ukuba umsebenzisi unokubonelela ngomoya othembekileyo xa ewufuna kakhulu.
Ukwandiswa kweSakhono
Enye inzuzo yecarbon fiber composite cylinders kukukwazi kwabo ukubamba umoya omninzi okanye ioksijini kwiphakheji encinci, elula. Esi sikhundla sandisiweyo sivumela amaxesha ukubaleka amade, ukunika abasebenzisi imizuzu eyongezelelweyo yomoya ophefumlayo ukuba baphume ngokukhuselekileyo kwindawo eyingozi. Ngokomzekelo, acarbon fiber composite cylinderinokunikezela ngobonelelo lomoya olufanayo njengecylinder yentsimbi kodwa ngobuninzi obuncinci kunye nobunzima, iyenze isebenziseke ngakumbi ukuba isetyenziswe kwiindawo ezivaliweyo okanye kubasebenzisi abafuna ukuhamba ngokukhawuleza.
Ukusetyenziswa kwee-EEBDs
Ii-EEBDs ziqhele ukusetyenziswa kumashishini apho abasebenzi banokuthi babe sesichengeni somoya oyingozi. Ezi ziquka:
- Ishishini laseLwandle: Kwiinqanawa, i-EEBD isoloko ifunwa njengenxalenye yezixhobo zokhuseleko. Kwimeko yomlilo okanye igesi evuzayo, abasebenzi banokusebenzisa i-EEBD ukubaleka kumagumbi enjini okanye kwezinye iindawo ezivaliweyo apho umoya uba yingozi.
- Ukwembiwa kwemigodi: Imigodi idume kakubi ngeegesi ezinobungozi kunye neendawo eziphelelwa yioksijini. I-EEBD ibonelela abasebenzi basezimayini ngeendlela ezikhawulezayo neziphathwayo zokubaleka ukuba umoya uba ungakhuselekanga ukuphefumla.
- Izityalo zoShishino: Iifektri kunye nezityalo ezisebenza ngeekhemikhali ezinobungozi okanye iinkqubo zinokufuna ukuba abasebenzi basebenzise ii-EEBD ukuba kukho ukuvuza okanye ukuqhuma kwegesi, okukhokelela kumoya onetyhefu.
- Inqwelomoya: Ezinye iinqwelomoya zithwala ii-EEBDs ukukhusela amalungu abasebenzi kunye nabakhweli kwi-inhalation yomsi okanye ukungabikho kwe-oksijini kwimeko yongxamiseko ebhodini.
- Ishishini leoli negesi: Abasebenzi kwiindawo zokucoca i-oyile okanye amaqonga okomba angaphandle konxweme bahlala bexhomekeke kwii-EEBD njengenxalenye yezixhobo zabo zokuzikhusela ukuze babaleke ukuvuza kwerhasi okanye imililo.
EEBD vs. SCBA
Kubalulekile ukuqonda umahluko phakathi kwe-EEBD kunye ne-Self-Contained Breathing Apparatus (SCBA). Ngelixa zombini ezi zixhobo zibonelela ngomoya ophefumlayo kwiatmosphere eyingozi, ziyilelwe iinjongo ezahlukeneyo:
- EEBD: Umsebenzi ophambili we-EEBD kukubonelela ngobonelelo lomoya lwexesha elifutshane ngeenjongo zokubaleka. Ayenzelwanga ukusetyenziswa ixesha elide kwaye ngokuqhelekileyo isetyenziselwa ukukhutshwa ngokukhawuleza kwiindawo ezinetyhefu okanye ezingenayo i-oxygen. Ii-EEBDs zincinci, zikhaphukhaphu, kwaye zithe tye ngakumbi ukusebenza kune-SCBAs.
- SCBA: I-SCBA, ngakolunye uhlangothi, isetyenziselwa imisebenzi yexesha elide, njengokucima umlilo okanye ukuhlangula imisebenzi. Iisistim ze-SCBA zibonelela ngobonelelo lomoya olumandla ngakumbi, oluhlala ukuya kuthi ga kwiyure, kwaye ziyilelwe ukusetyenziswa kwiimeko ezinobungozi ezongeziweyo. Ii-SCBA ziqhelekile ukuba zininzi kwaye zintsonkothe ngakumbi kune-EEBDs kwaye zibandakanya iimpawu eziphambili ezifana neegeyiji zoxinzelelo, ii-alam, kunye nezilawuli ezinokuhlengahlengiswa.
Ukugcinwa kunye nokuHlolwa kwee-EEBDs
Ukuqinisekisa ukuba i-EEBD ikulungele ukusetyenziswa ngexesha likaxakeka, ukugcinwa rhoqo kunye nokuhlolwa kubalulekile. Eminye yemisebenzi ephambili yolondolozo ibandakanya:
- Ukuhlolwa rhoqo: Ii-EEBD kufuneka zihlolwe ngamaxesha athile ukujonga naziphi na iimpawu zokuguga okanye umonakalo, ngakumbi kwimaski yobuso, i-harness, kunye ne-cylinder.
- Uvavanyo lweHydrostatic: Ikhabhon fiber composite cylinders kufuneka bahlole i-hydrostatic ngamaxesha aqhelekileyo ukuqinisekisa ukuba basenakho ukumelana noxinzelelo oluphezulu olufunekayo ukugcina umoya okanye i-oxygen. Olu vavanyo lubandakanya ukuzalisa isilinda ngamanzi kwaye uyicinezele ukujonga ukuvuza okanye ubuthathaka.
- Ugcino olululo: Ii-EEBD kufuneka zigcinwe kwindawo ecocekileyo, eyomileyo kude nelanga elithe ngqo okanye amaqondo obushushu agqithisileyo. Ukugcinwa okungafanelekanga kunokunciphisa ixesha lokuphila kwesixhobo kunye nokunciphisa ukusebenza kwayo.
Ukuqukumbela
Isixhobo Sokuphefumla Emergency Escape (EEBD) sisixhobo esibalulekileyo sokhuseleko kumashishini apho umoya onobungozi unokuvela ngokungalindelekanga. Isixhobo sinika ukunikezelwa kwexesha elifutshane lomoya ophefumulayo, okuvumela abasebenzi ukuba babaleke kwiindawo ezinobungozi ngokukhawuleza nangokukhuselekileyo. Ngokudityaniswa kwecarbon fiber composite cylinders, ii-EEBD ziye zaba khaphukhaphu, zomelele ngakumbi, kwaye zithembeke ngakumbi, ziphucula ukusebenza kwazo kwiimeko ezingxamisekileyo. Ukugcinwa ngokufanelekileyo kunye nokuhlolwa rhoqo kuqinisekisa ukuba ezi zixhobo zihlala zilungele ukwenza umsebenzi wazo wokusindisa ubomi xa zifuneka.
