Okuthandwayo Okuguqukayo Kuzisetshenziswa ze-SCBA: Ukushintsha ukusuka ku-Type-3 ukuya ku-Type-4 Carbon Fiber Cylinders

Isingeniso

Eminyakeni yamuva nje, kube nokuguquguquka okuphawulekayo eminyangweni yezicishamlilo, abezimo eziphuthumayo, kanye nabasebenzisi be-SCBA (Self-Contained Breathing Apparatus) mayelana nokwamukelwaI-Type-4 carbon fibre cylinders, kancane kancane ishintshe eyangaphambiliIsilinda esiyinhlanganisela yohlobo-3s. Lolu shintsho aluzenzeki kodwa lubonisa ukuthambekela okubanzi okusekelwe ekwehliseni isisindo, ukusebenza kahle, kanye nokuphumelela kwezindleko zesikhathi eside.

Lesi sihloko sibheka okuningiliziwe nokusebenzayo ngezizathu ezibangela lokhu kunyakaza, sichaza umehluko phakathi kwezinhlobo ezimbili zamasilinda, izinzuzo ezinikezwaUhlobo-4ubuchwepheshe, kanye nezinto ezicatshangelwa yiminyango nabahlinzeki uma benza izinguquko.

UkuqondaUhlobo-3vs.I-Type-4 Carbon Fiber Cylinders

I-Type-3 Cylinders

• Isakhiwo: Uhlobo-3 isilindas zihlanganisa ii-aluminium alloy liner yangaphakathi(imvamisa i-AA6061) isongwe ngokugcwele ngezendlalelo zenhlanganisela ye-carbon fibre.

• Isisindo: Lezi zilula kakhulu kunamasilinda ensimbi kodwa zisenesisindo esibonakalayo ngenxa ye-aluminium liner.

• Ukuqina: I-aluminium liner inikeza isakhiwo esiqinile sangaphakathi, okwenzaUhlobo-3 isilindaIhlala isikhathi eside kakhulu ezindaweni ezinzima.

I-Type-4 Cylinders

• Isakhiwo: Uhlobo-4 isilindas isici aipulasitiki (i-polymer-based) liner, futhi esongwe ngokugcwele nge-carbon fiber noma inhlanganisela ye-carbon nengilazi imicu.

• Isisindo: ZiyalinganaukukhanyakunaUhlobo-3 isilindas, ngezinye izikhathi kuze kufike30% ngaphansi, okuyinzuzo eyinhloko.

• I-Gas Barrier: I-plastic liner idinga ukwelashwa okwengeziwe noma izendlalelo zokuvimbela ukuvimbela ngempumelelo ukungena kwegesi.

Kungani ama-Burefighting Bureaus kanye nabasebenzisi be-SCBA beshintshelaUhlobo-4

1. Ukunciphisa Isisindo Nokukhathala komsebenzisi

Izicishamlilo zisebenza ngaphansi kokucindezeleka okukhulu, izimo ezinzima ngokomzimba. Igremu ngalinye liyabala uma uphethe izinto zokusebenza.Uhlobo-4 isilindas, ekubeni elula phakathi kwezinketho,ukunciphisa ubunzima bomzimba, ikakhulukazi phakathi nemishini yesikhathi eside noma ezindaweni ezivalekile.

• Isisindo esincane silingana kangconoukuhamba.

• Ukukhathala okuphansi kunomthelelaukuphepha okuphezulu nokusebenza kahle.

• Iwusizo ikakhulukaziabasebenzi abancane noma abadala, noma labo abahilelekile emisebenzini yokutakula enwetshiwe.

2. Ivolumu Yegesi Enyusiwe Yesisindo Esifanayo Noma Esincane

Ngenxa yesisindo esiphansi seUhlobo-4 isilindas, kuyenzeka ukuthwalaumthamo wamanzi ophakeme (isb, 9.0L esikhundleni sika-6.8L)ngaphandle kokwandisa umthwalo. Lokhu kusho okwengeziweisikhathi sokuphefumulaezimeni ezibucayi.

• Kuwusizo ukungenaukuhlenga okujulile or izinga eliphezulu lokucisha umlilo.

• Ubude bomoya obunwetshiwe kunciphisa isidingo sokushintshwa kwamasilinda okuvamile.

3. I-Ergonomics engcono ne-SCBA Compatibility

Amasistimu esimanje e-SCBA ahlelwa kabusha ukuze alingane kalulaUhlobo-4 isilindas. Ingqikithiisikhungo amandla adonsela phansi kanye balancewegiya uyathuthuka uma usebenzisa amasilinda alula, okuholela ekumeni okungcono nokuncipha kobunzima bokubuyela emuva.

• Ithuthuka ngokupheleleukunethezeka komsebenzisikanye nokulawula.

• Ihambisana nezintshaModular SCBA izinhleloyamukelwa eNyakatho Melika, eYurophu nasezingxenyeni ezithile ze-Asia.

Izindleko, Ukuqina, Nokucatshangelwa

1. Izindleko Zokuqala vs. Ukonga Umjikelezo Wokuphila

• Uhlobo-4 isilindas ziningikuyabiza phambilikunaUhlobo-3, ikakhulukazi ngenxa yezinto eziphambili kanye nokukhiqiza okuyinkimbinkimbi.

• Nokho, ukonga esikhathini eside kuvela ku:

  • Izindleko zokuthutha eziphansi

  • Ukulimala komsebenzisi okuncane nokukhathala

  • Isikhathi sokusebenza esinwetshiwe ngethangi ngalinye

2. Impilo Yesevisi Nezikhawu Zokuhlola Kabusha

• Uhlobo-3ngokuvamile ine-aimpilo yesevisi yeminyaka eyi-15,kuye ngezindinganiso zendawo.Uhlobo-4 isilindaImpilo yesevisi ye-NLL (No-Limited-Lifespan).

• Izikhathi zokuhlola i-Hydrostatic (ngokuvamile njalo eminyakeni emi-5) ziyefana, kodwaUhlobo-4kungase kudingeukuhlola okubukwayo eduzeukuthola noma yiziphi izinkinga ezingase zibe khona ze-delamination noma ezihlobene nomugqa.

3. Izinkathazo Zokugeleza Kwegesi

• Uhlobo-4 isilindas ingase ibe kancaneamazinga aphezulu okungena kwegesingenxa yezinsimbi zabo zepulasitiki.

• Kodwa-ke, izembatho zesimanje zokuvimbela izivimbelo nezinto ze-liner zinciphise kakhulu lokhu, zizenzeiphephile ekuphefumuleni umoyaizicelo uma zakhiwe kumazinga afanaEN12245 or I-DOT-CFFC.

Amathrendi Wokutholwa Ngokwesifunda

• i-America esenyakatho: Iminyango yezicishamlilo e-US naseCanada ihlanganisa kancane kancaneUhlobo-4 isilindas, ikakhulukazi eminyangweni yasemadolobheni.

• EYurophu: Ukucindezela okuqinile ngenxa yokuthobela okujwayelekile kwe-EN nokugxila kwe-ergonomics emazweni asenyakatho nentshonalanga ye-Europe.

• E-Asia: I-Japan ne-South Korea zingabamukeli bokuqala bezinhlelo ze-SCBA ezingasindi. Imakethe yezokuphepha yezimboni ekhulayo yaseShayina nayo ikhombisa izimpawu zenguquko.

• Middle East & Gulf: Ngokugxila kumayunithi aphendula ngokushesha kanye nezindawo ezishisa kakhulu,Uhlobo-4 isilindaI-s'lightweight kanye nokumelana nokugqwala kuyathandeka.

• Isifunda se-CIS: NgokwesikoUhlobo-3ebusayo, kodwa ngezinhlelo zesimanje ezikhona,Uhlobo-4izivivinyo ziyaqhubeka.

Umehluko Wokulungisa Nokugcina

• Uhlobo-4 isilindas kufanele kubeivikelwe ekuvezweni kwe-UVuma ingasetshenziswa, njengoba ama-polymers ekwazi ukuwohloka ngokuhamba kwesikhathi ngokuchayeka elangeni isikhathi eside.

• Ukuhlola okuvamile kufanele kubandakanye ukuhlolaukugoqa kwangaphandle kanye nesihlalo se-valvengezimpawu zokuguga noma zokulimala.

• Imishini efanayo yokuhlola i-hydro kanye nezinqubo zivame ukusetshenziswa njengalaphoUhlobo-3, nakuba njalo ukulandelaukuhlolwa kanye nemihlahlandlela yokuhlola yomkhiqizi.

Imicabango yokugcina

Ukushintsha kusukaUhlobo-3 to Uhlobo-4amasilinda e-carbon fibre emkhakheni wokucisha umlilo kanye ne-SCBA yi-isinyathelo esinengqondo esiya phambilieqhutshwa ukukhathazeka kwesisindo, izinzuzo zokusebenza kahle, nokuthuthukiswa kwe-ergonomic. Nakuba izindleko zokutholwa zingaba isici, izinhlangano eziningi ziyaqaphela izinzuzo zesikhathi eside zokushintshela kubuchwepheshe obusha, obulula.

Ochwepheshe abaphambili ukuphepha nokubekezela kwabo kuncike ezintweni zabo zokusebenza, ukusebenza okuthuthukisiwe, ukukhathala okuncishisiwe, namandla okuhlanganiswa esimanjemanjeUhlobo-4 isilindaszibenze bathuthuke okubalulekile emisebenzini ebalulekile empilweni.
