Ungabala kanjani i-SCBA Cylinder Capacity: Ukuqonda Isikhathi Sokusebenza Se-Carbon Fiber Cylinders

Isilinda Se-Self-Contained Breathing Apparatus (SCBA).s zibalulekile ekuhlinzekeni umoya ophefumulayo kubacimi bomlilo, abasebenzi bokutakula, kanye nabanye abasebenzi abasebenza ezindaweni eziyingozi. Ukwazi ukuthi isikhathi esingakananiI-SCBA cylinderizohlala ngesikhathi sokusetshenziswa ibalulekile ekuhleleni imisebenzi kanye nokuqinisekisa ukuphepha. Ubude besikhathi sokusebenza kwesilinda sincike kumthamo wayo, ingcindezi, nezinga lokuphefumula lomsebenzisi. Lesi sihloko sizokuhamba ngendlela yokubala umthamo we-I-SCBA cylinder, usebenzisa ifomula elula, ngokunaka okukhethekileisilinda esiyinhlanganisela ye-carbon fibres, ezisetshenziswa kabanzi ngenxa yokukhanya kwazo namandla.

I-SCBA CylinderOkuyisisekelo: Ivolumu kanye Nokucindezela

I-SCBA cylinders isitolo somoya ocindezelwe ngokucindezelwa okuphezulu, ovame ukukalwa ngamabha noma amaphawundi ngeyintshi yesikwele (PSI). Umthamo womoya ngaphakathi kwesilinda ngokuvamile uvezwa ngamalitha. Izinto ezimbili eziyinhloko ezinquma ukuthi ungakanani umoya otholakalayo yilezi:

• Isilinda Volume: Lona usayizi wangaphakathi wesilinda, ovame ukuvezwa ngamalitha (isb, 6.8-litre noma 9-litre).
• I-Cylinder Pressure: Ingcindezi lapho kugcinwa khona umoya, ngokuvamile phakathi kwamabha angama-200 no-300I-SCBA cylinders.

Isilinda esiyinhlanganisela ye-carbon fibres zidumile ezinhlelweni ze-SCBA ngoba zinikeza amandla okucindezela aphezulu (afika ku-300 bar) kuyilapho ilula kakhulu kunensimbi yomdabu noma amasilinda e-aluminium. Lokhu kuzenza zilungele izimo lapho abasebenzisi badinga ukuhamba ngokushesha noma isikhathi eside.

The Ifomula yokubala Ubude besikhathi se-SCBA

Isikhathi sokusebenza se-I-SCBA cylinderingabalwa kusetshenziswa ifomula elandelayo:

• I-“40″ kufomula imelela isilinganiso sokuphefumula komuntu ongaphansi kwezimo zokusebenza ezimaphakathi. Lesi silinganiso singahluka kuye ngokuthi umsebenzisi usebenza kanzima kangakanani, kodwa amalitha angama-40 ngomzuzu (L/min) yisibalo esijwayelekile.
• I-“-10″ ekugcineni kwefomula iwumkhawulo wokuphepha, oqinisekisa ukuthi umsebenzisi unesikhathi sokuphuma endaweni eyingozi ngaphambi kokuthi umoya uphele ngokuphelele.

Isibonelo sokubala:

Ake sibale ubude besikhathi sokusebenza ku-6.8-litrecarbon fibre SCBA isilinda, ucindezelwe ku-300 bar.

Kulesi sibonelo, i-I-SCBA cylinderizohlinzeka cishe imizuzu engama-35 yomoya ophefumulayo ngaphambi kokudinga ukushintshwa noma ukugcwaliswa kabusha. Lesi sibalo sithatha umsebenzi womzimba omaphakathi, futhi isikhathi sangempela sokusebenzisa singahluka uma umsebenzisi ezikhandla kakhulu noma ngaphansi.

Izici AffectingI-SCBA CylinderUbude besikhathi

Nakuba ifomula inikeza isilinganiso esiyisisekelo, izici ezimbalwa zingathonya

isikhathi sangempela se-I-SCBA cylinderiyasetshenziswa. Ukuqonda lokhu okuguquguqukayo kuyisihluthulelo sokuqinisekisa ukusebenza okuphephile.

1. Izinga lokuphefumula

Ifomula ithatha ukuphefumula okumaphakathi

izinga lehing lika-40 L/min, elihambisana nomsebenzi omaphakathi. Eqinisweni, izinga lokuphefumula lingashintsha ngokuya ngomthwalo womsebenzi womsebenzisi:

• Umsebenzi Ophansi: Uma umsebenzisi ephumule noma enza umsebenzi olula, izinga lokuphefumula lingaba phansi, cishe ku-20-30 L/min, okunganweba ubude besilinda.
• Umsebenzi ophezulu: Phakathi nomsebenzi onzima womzimba, njengokucisha umlilo noma ukutakula abantu, izinga lokuphefumula lingakhuphuka libe ngu-50-60 L/min noma ngaphezulu, linciphise ubude besilinda.

2. I-Cylinder Pressure

Amasilinda okucindezela okuphezulu anikeza umoya owengeziwe wevolumu efanayo.I-carbon fibre cylinders ngokuvamile asebenza ngezingcindezi ezifika kumabha angu-300, uma kuqhathaniswa namasilinda ensimbi noma e-aluminium, angase akhawulelwe kumabha angu-200. Ukucindezela okuphezulu kuvumelai-carbon fibre cylinders ukubamba umoya omningi ephaketheni elincane, elilula, ukwelula ubude besikhathi sokusebenza.

3. Imajini yokuphepha

Imajini yokuphepha eyakhelwe kufomula (imizuzu eyi-10) iqinisekisa ukuthi

umsebenzisi akaphelelwa umoya ngenkathi esesendaweni eyingozi. Kubalulekile ukuhlonipha lesi sivimbeli lapho ubala isikhathi sokusebenza futhi uhlela ukusetshenziswa komoya, ikakhulukazi ezimeni lapho umzila ophumayo ungathatha amaminithi ambalwa ukunqamula.

yena Iqhaza likaI-Carbon Fiber Composite Cylinders

Isilinda esiyinhlanganisela ye-carbon fibres sebeyinketho ekhethwayo yezinhlelo ze-SCBA ngenxa yokwakheka kwazo okungasindi kanye nekhono lokubamba izingcindezi eziphezulu. Uma kuqhathaniswa namasilinda ensimbi ne-aluminium,i-carbon fibre cylindersinikeza izinzuzo ezimbalwa:

• Isisindo: I-carbon fibre cylinders alula kakhulu kunensimbi, okwenza kube lula ukuwaphatha futhi anciphise ukukhathala kumsebenzisi phakathi nokusebenza okunwetshiwe.
• Ingcindezi Ephakeme: Angagcwaliswa kukucindezela kufika kubha engu-300, anikeze umoya owengeziwe ngaphandle kokukhulisa usayizi wesilinda.
• Ukuqina: Izinhlanganisela ze-carbon fibre ziqine ngokwedlulele, zikwazi ukumelana nezingcindezi eziphezulu kuyilapho zikwazi ukumelana nomthelela kanye nezici zemvelo.

Idizayini engasindi ibaluleke kakhulu kubasebenzi bokutakula abadinga ukuhlala behamba ngenkathi bephethe ezinye izinto zokusebenza, njengamathuluzi okucisha umlilo noma igiya lezokwelapha. Naphezu kwezinzuzo zabo,i-carbon fibre cylinderiza nezinye izimfuneko zokulungisa ezengeziwe, njengokuhlola okuvamile kwe-hydrostatic ukuze kuqinisekiswe ukuthi zihlala ziphephile ngaphansi kwengcindezi.

Ukuhlolwa kwe-Hydrostatic kanyeI-SCBA CylinderIsondlo

Ukugcina ukwethembeka kweI-SCBA cylinders, okuhlanganisa amamodeli we-carbon fibre, ukugcinwa okuvamile kubalulekile. Lokhu kuhlanganisa:

• Ukuhlola Okubonakalayo: Hlola umonakalo, njengokuqhekeka noma ama-dent, ngaphambi kokusetshenziswa ngakunye.
• Ukuhlolwa kwe-Hydrostatic: I-carbon fiberI-SCBA cylinders ngokuvamile zidinga ukuhlolwa kwe-hydrostatic njalo eminyakeni emihlanu ukuze kuqinisekiswe ukuthi ziyakwazi ukubhekana nezingcindezi eziphezulu ezihilelekile. Lokhu kuhlola kuhlola noma yikuphi ukunwetshwa kusilinda okungase kubonise ukuba buthaka kwento.
• Ukumiselela: Ngisho nokunakekelwa okufanele,carbon fibre SCBA isilindas zinesikhathi esinqunyiwe sokuphila, ngokuvamile cishe iminyaka eyi-15, emva kwalokho kufanele zishintshwe.

Isiphetho

Ukwazi ukubala umthamo kanye nesikhathi sokusebenza seI-SCBA cylinders yiko

kubalulekile kunoma ubani othembele kulawa madivayisi ezindaweni eziyingozi. Ukusebenzisa ifomula(Umthamo × Ingcindezi) / 40 – 10,wenan ukulinganisa isikhathi esitholakalayo kunoma iyiphi isilinda, ukhumbula ukuthi amazinga okuphefumula, ingcindezi, nemingcele yokuphepha konke kunendima esikhathini sokugcina.

Isilinda esiyinhlanganisela ye-carbon fibres, ngomklamo wabo ongasindi kanye nekhono lokubamba izingcindezi eziphezulu, ukukhetha okudumile kumasistimu e-SCBA. Banikeza isikhathi eside sokusebenza kanye nokuhamba okuthuthukisiwe uma kuqhathaniswa namasilinda ensimbi noma e-aluminium. Kodwa-ke, ukunakekelwa okuvamile, okuhlanganisa ukuhlolwa okubonakalayo nokuhlolwa kwe-hydrostatic, kubalulekile ukuze kuqinisekiswe ukuthi la masilinda ahlala ephephile futhi esebenza kahle kukho konke ukuphila kwawo kwesevisi.

Ukuqonda lezi zici zeI-SCBA cylinderumthamo uzosiza ekuqinisekiseni ukusetshenziswa okuphephile nangempumelelo ezindaweni eziyinselele, lapho yonke iminithi yomoya ophefumulayo ingenza umehluko.
