Ungabala njani i-SCBA Cylinder Capacity: Ukuqonda ixesha lokuSebenza kweCarbon Fiber Cylinders

I-Self-Contained Breathing Apparatus (SCBA) cylinders zibalulekile ekuboneleleni umoya ophefumulayo kubacimi bomlilo, abasebenzi bokuhlangula, kunye nabanye abasebenzi abasebenza kwiindawo ezinobungozi. Ukwazi ukuba ixesha elingakananiSCBA isilindaiya kuhlala ngexesha lokusetyenziswa kubalulekile ekucwangciseni imisebenzi kunye nokuqinisekisa ukhuseleko. Ubude bexesha lokusebenza kwe-cylinder kuxhomekeke kumthamo wayo, uxinzelelo, kunye nesantya sokuphefumla komsebenzisi. Eli nqaku liza kukuhamba ngendlela yokubala umthamo weSCBA isilinda, usebenzisa i-formula elula, kunye nengqwalasela ekhethekileyocarbon fiber composite cylinders, ezisetyenziswa ngokubanzi ngenxa yobunzima bazo kunye namandla.

I-SCBA CylinderIzinto ezisisiseko: Umthamo kunye noxinzelelo

SCBA isilindas ukugcina umoya ocinezelweyo kuxinzelelo oluphezulu, ngokuqhelekileyo kulinganiswa imivalo okanye iiponti nganye square intshi (PSI). Umthamo womoya ngaphakathi kwi-cylinder udla ngokubonakaliswa ngeelitha. Izinto ezimbini eziphambili ezibonisa ukuba ungakanani umoya okhoyo zezi:

• Isilinda Volume: Lo bukhulu bangaphakathi be-cylinder, edlalwa rhoqo kwiilitha (umzekelo, i-6.8-litre okanye i-9-litre).
• Uxinzelelo lweSilinda: Uxinzelelo apho umoya ugcinwa khona, ngokuqhelekileyo phakathi kwe-200 kunye ne-300 bar yeSCBA isilindas.

Ikhabhon fibre composite cylinders zithandwa kwiinkqubo ze-SCBA kuba zinika amandla aphezulu oxinzelelo (ukuya kwi-bar ye-300) ngelixa zikhanya kakhulu kunentsimbi yendabuko okanye iisilinda ze-aluminium. Oku kubenza balungele iimeko apho abasebenzisi kufuneka bahambe ngokukhawuleza okanye ixesha elide.

The Ifomula yokubala uBude be-SCBA

Ubude bexesha lokusebenza kweSCBA isilindaingabalwa kusetyenziswa le fomula ilandelayo:

• I-"40" kwifomula imele umyinge wokuphefumla komntu ophantsi kweemeko zomsebenzi ophakathi. Eli xabiso lingahluka ngokuxhomekeka kwindlela umsebenzisi asebenza nzima ngayo, kodwa iilitha ezingama-40 ngomzuzu (L / min) ngumfanekiso oqhelekileyo.
• I-"-10" ekupheleni kwefomula ngumda wokhuseleko, ukuqinisekisa ukuba umsebenzisi unexesha lokuphuma kwindawo enobungozi phambi kokuba umoya uphele ngokupheleleyo.

Umzekelo wokubala:

Masibale ubude bexesha lokusebenza kwi-6.8-litrecarbon fiber SCBA cylinder, icinezelwe ukuya kwi-300 bar.

Kulo mzekelo, iSCBA isilindaingabonelela malunga nemizuzu engama-35 yomoya ophefumlayo phambi kokuba ufune ukutshintshwa okanye uzaliswe kwakhona. Olu balo luthatha umsebenzi womzimba ophakathi, kwaye ixesha lokusetyenziswa linokwahluka ukuba umsebenzisi uyazibhokoxa ngaphezulu okanye ngaphantsi.

Izinto AffeukubambaI-SCBA CylinderUbude bexesha

Ngelixa ifomula ibonelela ngoqikelelo olusisiseko, izinto ezininzi zinokuchaphazela

ixesha lokwenyani leSCBA isilindaesebenzayo. Ukuqonda ezi ziguquguqukayo ngundoqo ekuqinisekiseni imisebenzi ekhuselekileyo.

1. Izinga lokuphefumla

Ifomula ithatha ukuphefumla okuphakathi

izinga le-hing ye-40 L / min, ehambelana nomsebenzi ophakathi. Ngokwenyani, izinga lokuphefumla lingaguquguquka ngokuxhomekeke kumthwalo womsebenzi womsebenzisi:

• Umsebenzi ophantsi: Ukuba umsebenzisi uphumle okanye wenza umsebenzi wokukhanya, izinga lokuphefumula linokuba liphantsi, malunga ne-20-30 L / min, eya kwandisa ubude be-cylinder.
• Umsebenzi ophezulu: Ngethuba lomsebenzi onzima womzimba, njengokulwa nomlilo okanye ukuhlangula abantu, amazinga okuphefumula anganyuka ukuya kwi-50-60 L / min okanye ngaphezulu, ukunciphisa ubude be-cylinder.

2. Uxinzelelo lweSilinda

Iisilinda zoxinzelelo oluphezulu zibonelela ngomoya ongaphezulu kumthamo ofanayo.Ikhabhoni fiber cylinders ngokuqhelekileyo zisebenza kwiingcinezelo ukuya kwi-300 bar, xa kuthelekiswa nentsimbi okanye iisilinda ze-aluminium, ezinokulinganiselwa kwi-bar ye-200. Uxinzelelo oluphezulu luvumelacarbon fiber cylinders ukubamba umoya omninzi kwiphakheji encinci, elula, ukwandisa ubude bexesha lokusebenza.

3. Umda woKhuseleko

Umda wokhuseleko owakhelwe kwifomula (-10 imizuzu) uqinisekisa ukuba

umsebenzisi akaphelelwa ngumoya ngelixa ekwimekobume eyingozi. Kubalulekile ukuhlonipha esi sithinteli xa ubala ixesha lokusebenza kunye nokucwangcisa ukusetyenziswa komoya, ngakumbi kwiimeko apho indlela yokuphuma inokuthatha imizuzu emininzi ukunqumla.

T

yena Indima yeI-Carbon Fiber Composite Cylinders

Ikhabhon fibre composite cylinders ibe lukhetho olukhethwayo kwiinkqubo ze-SCBA ngenxa yoyilo lwazo olukhaphukhaphu kunye nokukwazi ukubamba uxinzelelo oluphezulu. Xa kuthelekiswa neesilinda zentsimbi kunye ne-aluminium,carbon fiber cylinders zibonelela ngeenzuzo ezininzi:

• Ubunzima: Ikhabhoni fiber cylinderI-s ilula kakhulu kunentsimbi, okwenza kube lula ukuyiphatha kunye nokunciphisa ukudinwa komsebenzisi ngexesha lemisebenzi eyandisiweyo.
• Uxinzelelo oluPhezulu: Zinokuzaliswa kwiingcinezelo ukuya kwi-bar ye-300, ukubonelela ngomoya ongaphezulu ngaphandle kokunyusa ubukhulu be-cylinder.
• Ukuqina: Iicomposites zeCarbon fibre zomelele kakhulu, ziyakwazi ukumelana noxinzelelo oluphezulu ngelixa zikwamelana neempembelelo kunye nezinto zokusingqongileyo.

Uyilo olulula lubaluleke kakhulu kubasebenzi bokuhlangula abafuna ukuhlala behamba ngelixa bephethe ezinye izixhobo, ezifana nezixhobo zokucima umlilo okanye izixhobo zonyango. Ngaphandle kweenzuzo zabo,carbon fiber cylinderziza nezinye iimfuno ezongezelelweyo zogcino, ezifana novavanyo rhoqo lwe-hydrostatic ukuqinisekisa ukuba zihlala zikhuselekile phantsi koxinzelelo.

Uvavanyo lweHydrostatic kunyeI-SCBA CylinderIsondlo

Ukugcina ukuthembeka kweSCBA isilindas, kubandakanywa iimodeli ze-carbon fiber, ukugcinwa rhoqo kubalulekile. Oku kuquka:

• Ukuhlola Okubonwayo: Jonga umonakalo, njengokuqhekeka okanye ukubola, phambi kokusetyenziswa ngakunye.
• Uvavanyo lweHydrostatic: Ifayibha yeCarbonSCBA isilindas zifuna uvavanyo lwe-hydrostatic rhoqo emva kweminyaka emihlanu ukuqinisekisa ukuba banokumelana noxinzelelo oluphezulu olubandakanyekayo. Olu vavanyo luhlola naluphi na ukwandiswa kwi-cylinder enokuthi ibonise ubuthathaka bezinto eziphathekayo.
• Ukutshintshwa: Nokuba ugcinwe kakuhle,carbon fiber SCBA cylinders zinobomi obunqamlekileyo, ngokuqhelekileyo malunga ne-15 leminyaka, emva koko kufuneka zitshintshwe.

Ukuqukumbela

Ukwazi ukubala umthamo kunye nobude bexesha lokusebenzaSCBA isilindas yi

kubalulekile kuye nabani na oxhomekeke kwezi zixhobo kwindawo enobungozi. Ukusebenzisa ifomula(Umthamo × Uxinzelelo) / 40 – 10,wenan ukuqikelela ixesha elikhoyo nakweyiphi na isilinda, ugcine engqondweni ukuba amazinga okuphefumla, uxinzelelo, kunye nemida yokhuseleko zonke zidlala indima kwixesha lokugqibela.

Ikhabhon fibre composite cylinders, kunye noyilo lwabo olukhaphukhaphu kunye nokukwazi ukubamba uxinzelelo oluphezulu, lukhetho oludumileyo kwiinkqubo ze-SCBA. Banikezela ixesha elide lokusebenza kunye nokuhamba okuphuculweyo xa kuthelekiswa nentsimbi okanye iisilinda ze-aluminium. Nangona kunjalo, ukugcinwa rhoqo, kubandakanywa ukuhlolwa okubonakalayo kunye nokuhlolwa kwe-hydrostatic, kubalulekile ukuqinisekisa ukuba ezi zilinda zihlala zikhuselekile kwaye zisebenza ubomi babo bonke benkonzo.

Ukuqonda le miba yeSCBA isilindaumthamo uya kunceda ukuqinisekisa ukusetyenziswa okukhuselekileyo kunye nokusebenzayo kwiindawo ezicela umngeni, apho yonke imzuzu yomoya ophefumulayo ingenza umehluko.
