Sida Loo Xisaabiyo Awoodda Dabaqadaha SCBA: Fahmidda Muddada Shaqeynta ee Xajiyeyaasha Kaarboon Fiber

Qalabka Neefsashada ee Is-Contained (SCBA) dhululubos ayaa muhiim u ah bixinta hawo neefta leh ee dab-demiska, shaqaalaha samatabbixinta, iyo shaqaalaha kale ee ka shaqeeya meelaha khatarta ah. Ogaanshaha inta uu le'eg yahaydhululubo SCBAsocon doona inta lagu jiro isticmaalka ayaa muhiim u ah qorsheynta hawlgallada iyo hubinta amniga. Muddada shaqaynaysa dhululubo waxay ku xidhan tahay mugga, cadaadiska, iyo heerka neefsiga isticmaaluhu. Maqaalkani wuxuu ku dhex socon doonaa sida loo xisaabiyo awoodda adhululubo SCBA, iyadoo la isticmaalayo qaacido fudud, oo fiiro gaar ah lehdhululubo ka kooban fiber carbons, kuwaas oo si weyn loo isticmaalo culeyskooda iyo xooggooda awgeed.

Silinder SCBAAasaaska: Mugga iyo Cadaadiska

dhululubo SCBAs bakhaarka hawada cadaadisku saaran yahay cadaadis sare, sida caadiga ah lagu qiyaaso baararka ama rodol halkii inji (PSI). Mugga hawada gudaha dhululubada waxaa badanaa lagu muujiyaa litir. Labada arrimood ee ugu waaweyn ee go'aamiya inta hawo la heli karo waa:

  • Mugga Silinder: Tani waa cabbirka gudaha ee dhululubada, oo inta badan lagu muujiyo litir (tusaale, 6.8-litir ama 9-litir).
  • Cadaadiska SilinderCadaadiska hawada lagu kaydiyo, caadi ahaan inta u dhaxaysa 200 iyo 300 bar eedhululubo SCBAs.

dhululubo ka samaysan fiber kaarboons waxay caan ku yihiin nidaamyada SCBA sababtoo ah waxay bixiyaan awood cadaadis sare leh (ilaa 300 bar) iyagoo aad uga fudud birta dhaqameed ama dhululubada aluminium. Tani waxay ka dhigaysaa inay ku habboon yihiin xaaladaha ay isticmaalayaashu u baahan yihiin inay si degdeg ah u guuraan ama muddo dheer.

The Formula Xisaabinta Muddada SCBA

Muddada shaqada ee adhululubo SCBAwaxaa lagu xisaabin karaa qaacidooyinka soo socda:

Muddada shaqada (daqiiqado gudaheed) = (Mugga Silinder (L) × Cadaadis (Bar)) / 40 - 10
  • "40" ee ku jirta qaaciidada waxay ka dhigan tahay celceliska heerka neefsiga ee qofka ku jira xaalad shaqo oo dhexdhexaad ah. Heerkani wuu kala duwanaan karaa iyadoo ku xidhan hadba inta adeegsaduhu u shaqeeyo, laakiin 40 litir daqiiqadii (L/min) waa jaantus caadi ah.
  • "-10" ee dhamaadka qaacidada waa xad badbaado, hubinta in isticmaaluhu uu haysto wakhti uu kaga baxo aagga khatarta ah ka hor inta aysan hawadu dhammaanin.

Xisaabinta Tusaalaha:

Aynu xisaabino muddada shaqada ee 6.8-litirfiber carbon SCBA dhululubo, lagu cadaadiyay ilaa 300 bar.

Muddada shaqada = (6.8 L × 300 bar) / 40 - 10 = 2040/40 - 10 = 51 - 10 = 35 daqiiqo

Tusaalahan, thedhululubo SCBAwaxay ku siin doontaa qiyaastii 35 daqiiqo hawo neefsan karta ka hor inta aan loo baahnayn in la beddelo ama la buuxiyo. Xisaabintani waxay u qaadanaysaa dhaqdhaqaaq jireed dhexdhexaad ah, wakhtiga isticmaalka dhabta ahi wuu kala duwanaan karaa haddii isticmaaluhu uu dadaalayo in ka badan ama ka yar.

Iyadoo qaacidadu ay bixiso qiyaas aasaasi ah, dhowr arrimood ayaa saameyn kara

muddada dhabta ah ee adhululubo SCBAla isticmaalo. Fahamka doorsoomayaashan ayaa fure u ah xaqiijinta hawlgallada nabdoon.

1. Heerka Neefsashada

Habkani waxa uu qaadanayaa naaso dhexdhexaad ah

heerka garaaca ee 40 L/min, taas oo u dhiganta dhaqdhaqaaqa dhexdhexaad ah. Xaqiiqda, heerka neefsashadu wuu is beddeli karaa iyadoo ku xiran culeyska shaqada ee isticmaalaha:

  • Dhaqdhaqaaq hooseeya: Haddii isticmaaluhu uu nasasho ku jiro ama uu qabanayo shaqo fudud, heerka neefsashadu wuu yaraan karaa, qiyaastii 20-30 L/daqiiqo, taas oo kordhin doonta muddada dhululubada.
  • Waxqabad SareInta lagu jiro dhaqdhaqaaq jireed oo culus, sida la dagaallanka dabka ama badbaadinta dadka, heerarka neefsashadu waxay kordhin karaan 50-60 L/daqiiqo ama ka badan, yaraynta muddada dhululubada.

2. Cadaadiska Silinder

Dhululubada cadaadiska sare waxay bixiyaan hawo badan oo isku mid ah.Silinda fiber kaarboons sida caadiga ah waxay ku shaqeeyaan cadaadis gaaraya 300 bar, marka la barbar dhigo birta ama dhululubada aluminium, kuwaas oo ku koobnaan kara 200 bar. Cadaadiska sare ayaa ogolaanayadhululubo fiber carbons in lagu hayo hawo badan xirmo ka yar, ka fudud, kordhinta muddada shaqada.

3. Margin Badbaadada

Xadka badbaadada ee lagu dhisay qaacidada (-10 daqiiqo) waxay hubisaa in

Isticmaaluhu ma dhammaan hawo inta uu weli ku jiro deegaan khatar ah. Waa muhiim in la ixtiraamo kaydkan marka la xisaabinayo wakhtiga shaqada oo la qorsheynayo isticmaalka hawada, gaar ahaan xaaladaha meesha laga baxo ay qaadan karto dhowr daqiiqo in la maro.

Isaga DoorkiiSilinder ka kooban Fiber Kaarboons

dhululubo ka samaysan fiber kaarboons waxay noqdeen doorashada la door bidayo ee nidaamyada SCBA sababtoo ah naqshadooda fudud iyo awooda ay ku xajin karaan cadaadisyo sare. Marka la barbardhigo birta iyo aluminium dhululubada,dhululubo fiber carbons waxay bixiyaan faa'iidooyin dhowr ah:

  • Miisaanka: Silinda fiber kaarboons aad bay uga fudud yihiin birta, taasoo ka dhigaysa inay u fududaato qaadista iyo yaraynta daalka isticmaalaha inta lagu jiro hawlgallada la dheereeyey.
  • Cadaadis sare: Waxaa lagu buuxin karaa cadaadis ilaa 300 bar, siinaya hawo badan iyada oo aan la kordhin xajmiga dhululubada.
  • Waarta: Isku-dhafka fiber-ka-carbon waa mid aad u xoog badan, awood u leh inuu u adkeysto cadaadiska sare isagoo sidoo kale u adkeysanaya saameynta iyo arrimaha deegaanka.

Naqshadaynta khafiifka ah ayaa si gaar ah muhiim ugu ah shaqaalaha samatabbixinta kuwaas oo u baahan in ay sii socdaan inta ay wataan qalab kale, sida qalabka dab-damiska ama qalabka caafimaadka. In kasta oo ay faa'iido u leeyihiin,dhululubo fiber carbons waxay la yimaadaan qaar ka mid ah shuruudaha dayactirka dheeraadka ah, sida baaritaanka joogtada ah ee hydrostatic si loo hubiyo inay ku badbaadaan cadaadiska.

Baaritaanka Hydrostatic iyoSilinder SCBADayactirka

Si loo ilaaliyo kalsoonidadhululubo SCBAs, oo ay ku jiraan moodooyinka fiber carbon, dayactirka joogtada ah waa lama huraan. Tan waxaa ka mid ah:

  • Kormeero MuuqaalIska hubi burburka, sida dildilaaca ama jeexjeexyada, ka hor isticmaalka kasta.
  • Baaritaanka Hydrostatic: fiber carbondhululubo SCBAs sida caadiga ah waxay u baahan yihiin baaritaanka hydrostatic shantii sanoba mar si loo hubiyo inay xamili karaan cadaadiska sare ee ku lug leh. Tijaabadani waxay hubinaysaa balaadhinta dhululubo ee laga yaabo inay muujiso daciifnimada walxaha.
  • Beddelka: Xataa iyada oo la dayactirayo,fiber carbon SCBA dhululubos waxay leeyihiin cimrigooda xaddidan, badanaa qiyaastii 15 sano, ka dib waa in la beddelaa.

Gabagabo

Ogaanshaha sida loo xisaabiyo awoodda iyo muddada shaqadadhululubo SCBAs waa

muhiim u ah qof kasta oo ku tiirsan qalabkan meelaha khatarta ah. Isticmaalka caanaha(Cadadka × Cadaadis) / 40 - 10, waxaad can qiyaas waqtiga laga heli karo dhululubo kasta, iyadoo maskaxda lagu hayo in heerarka neefsashada, cadaadiska, iyo xad dhaafka badbaadada ay dhamaantood door ka ciyaaraan muddada ugu dambeysa.

dhululubo ka samaysan fiber kaarboons, oo leh naqshadooda khafiifka ah iyo awoodda ay ku xajin karaan cadaadisyo sare, ayaa ah doorasho caan ah oo loogu talagalay nidaamyada SCBA. Waxay bixiyaan waqtiyo shaqo oo dheer iyo dhaqdhaqaaqa la hagaajiyay marka loo eego birta ama aluminium dhululubada. Si kastaba ha ahaatee, dayactirka joogtada ah, oo ay ku jiraan baaritaannada muuqaalka iyo baaritaanka biyaha-static, ayaa muhiim ah si loo hubiyo in dhululubadani ay badbaado iyo waxtar u noqdaan inta ay nool yihiin adeeggooda.

Fahamka dhinacyadandhululubo SCBAAwooddu waxay kaa caawin doontaa hubinta isticmaalka badbaadada iyo waxtarka leh ee jawiga adag, halkaas oo daqiiqad kasta oo hawo neefsasho ah ay isbeddel ku samayn karto.
