Self-Contained Breathing Apparatus (SCBA) tanks yog cov cuab yeej siv kev nyab xeeb tseem ceeb siv nyob rau hauv ntau yam kev lag luam, suav nrog kev tua hluav taws, kev ua haujlwm cawm, thiab kev tuav cov khoom phom sij. Cov tso tsheb hlau luam no muab cov cua ua pa rau cov neeg siv uas yuav tsum tau ua haujlwm hauv ib puag ncig uas huab cua tsis huv lossis cov pa oxygen txaus txaus ntshai. To taub dab tsiSCBA lub tanks tau ntim nrog thiab cov ntaub ntawv siv los tsim lawv yog qhov tseem ceeb rau kev txaus siab rau lawv txoj haujlwm thiab ua kom lawv siv tau zoo thaum muaj xwm txheej ceev.
Dab tsiSCBA Tanks Ntim
SCBA lub tanks, tseem hu ua lub tog raj kheej, yog tsim los khaws thiab muab cov cua compressed lossis oxygen rau tus neeg hnav. Nov yog cov ncauj lus kom ntxaws txog cov ntsiab lus thiab kev tsim kho ntawm cov tank no:
1. Compressed Cua
Feem ntauSCBA lub tanks yog ntim nrog compressed cua. Compressed cua yog huab cua uas tau raug pressurized mus rau theem siab tshaj atmospheric siab. Qhov kev ua haujlwm siab no tso cai rau huab cua ntau npaum li cas rau hauv lub tank me me, ua rau nws siv tau rau ntau lub sijhawm. Compressed cua hauvSCBA lub tanks feem ntau muaj xws li:
- Oxygen:Kwv yees li 21% ntawm huab cua yog oxygen, uas yog tib feem pua ntawm cov huab cua ntawm hiav txwv theem.
- Nitrogen thiab lwm yam Gases:Qhov seem 79% yog tsim los ntawm nitrogen thiab cov kab ntawm lwm cov pa roj uas muaj nyob hauv qhov chaw.
Lub compressed cua nyob rau hauvSCBA lub tanks yog purified kom tshem tawm impurities, kom ntseeg tau tias nws muaj kev nyab xeeb rau kev ua pa txawm nyob rau hauv ib puag ncig tsis huv.
2. Compressed Oxygen
Hauv qee qhov tshwj xeeb SCBA units, cov tso tsheb hlau luam tau ntim nrog cov pa ntshiab compressed tsis yog cua. Cov chav no yog siv rau hauv cov xwm txheej tshwj xeeb uas xav tau ntau dua cov pa oxygen lossis qhov chaw huab cua tsis zoo. Compressed oxygen feem ntau yog siv rau hauv:
- Kev kho mob xwm txheej ceev:Qhov twg cov pa ntshiab yuav xav tau rau cov neeg mob uas muaj teeb meem ua pa.
- Kev ua haujlwm siab siab:Qhov twg cov qib oxygen qis dua, thiab qhov siab dua ntawm cov pa oxygen yog qhov zoo.
Kev tsim kho ntawmSCBA Tanks
SCBA lub tanks yog tsim los tiv thaiv kev kub ntxhov thiab hnyav hnyav. Kev xaiv cov khoom siv hauv kev tsim kho ntawm cov tso tsheb hlau luam yog qhov tseem ceeb rau lawv cov kev ua tau zoo thiab kev nyab xeeb.Carbon fiber ntau lub tog raj kheejs yog qhov kev xaiv nrov vim lawv cov khoom zoo tshaj. Nov yog saib ze dua ntawm cov ntaub ntawv no:
1. Carbon Fiber Composite Lub tog raj kheejs
Carbon fiber ntau lub tog raj kheejs tau dav siv hauv SCBA systems vim lawv lub zog thiab lub teeb yuag. Cov khoom tseem ceeb ntawm cov cylinders muaj xws li:
- Sab hauv Liner:Sab hauv liner ntawm lub tog raj kheej, feem ntau yog ua los ntawm cov ntaub ntawv zoo li txhuas lossis yas, tuav cov cua compressed lossis oxygen.
- Carbon Fiber qhwv:Cov txheej txheej ntawm lub tog raj kheej yog tsim los ntawm cov khoom siv carbon fiber ntau. Cov pa roj carbon fiber ntau yog cov khoom siv muaj zog, sib zog ua kom muaj zog-rau-hnyav piv thiab tiv thaiv kev cuam tshuam thiab corrosion.
Qhov zoo ntawmCarbon Fiber Composite Lub tog raj kheejs:
- Lub teeb: Carbon fiber ntau lub tog raj kheejs yog ntau sib dua piv rau cov tsoos hlau lossis txhuas lub tog raj kheej. Qhov no ua rau lawv yooj yim nqa thiab tuav, uas yog qhov tseem ceeb tshwj xeeb tshaj yog nyob rau hauv cov xwm txheej hnyav xws li kev tua hluav taws lossis kev cawm dim.
- Siab zog:Txawm hais tias lub teeb yuag,carbon fiber composite lub tog raj kheejs muaj zog heev thiab muaj peev xwm tiv taus kev kub ntxhov. Qhov no ua kom ntseeg tau tias lub tog raj kheej tuaj yeem tuav cov cua compressed lossis oxygen yam tsis muaj kev pheej hmoo ntawm kev tawg.
- Durability:Carbon fiber ntau tiv taus corrosion thiab kev puas tsuaj los ntawm ib puag ncig yam. Qhov no ntxiv rau lub neej ntev ntawm lub tog raj kheej, ua rau lawv txhim khu kev qha txawm nyob rau hauv hnyav hnyav.
- Kev ua tau zoo:Tus tsim ntawmcarbon fiber lub tog raj kheejs tso cai rau lawv khaws huab cua ntau dua los yog oxygen hauv qhov chaw me me, muab cov neeg siv nrog lub tshuab ua pa ntau dua thiab ua tau zoo.
2. Lwm yam khoom siv
- Aluminium Liner:Ib txhiaSCBA lub tanks siv aluminium liner, uas yog sib dua li hlau thiab muab kev tiv thaiv zoo rau corrosion. Cov tso tsheb hlau luam no feem ntau qhwv nrog cov khoom sib xyaw, xws li fiberglass lossis carbon fiber, txhawm rau txhim kho lawv lub zog.
- Steel Tank:Cov tso tsheb hlau luam SCBA yog tsim los ntawm cov hlau, uas muaj zog tab sis hnyav dua li txhuas lossis cov khoom sib xyaw. Steel tanks tseem siv nyob rau hauv qee daim ntawv thov tab sis tau maj mam hloov los ntawm lwm txoj kev sib dua.
Kev tu thiab kev nyab xeeb
Ua kom covSCBA lub tanks tau sau kom raug thiab khaws cia kom raug yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm:
- Kev tshuaj xyuas tsis tu ncua: SCBA lub tanks yuav tsum tau tshuaj xyuas tsis tu ncua rau cov cim qhia ntawm kev hnav lossis kev puas tsuaj. Qhov no suav nrog kev tshuaj xyuas cov dents, tawg, lossis lwm yam teeb meem uas tuaj yeem cuam tshuam lub tank kev ncaj ncees.
- Kev Ntsuas Hydrostatic: SCBA lub tanks yuav tsum tau kuaj xyuas raws sij hawm hydrostatic kom ntseeg tau tias lawv tuaj yeem tiv taus qhov siab siab uas lawv tau tsim los rau. Qhov no suav nrog sau lub tank nrog dej thiab nias nws los xyuas seb puas los yog tsis muaj zog.
- Sau kom raug:Lub tank yuav tsum tau sau los ntawm cov kws tshaj lij los xyuas kom meej tias cov pa lossis oxygen compressed rau qhov raug siab thiab lub tank muaj kev nyab xeeb siv.

SCBA lub tankNws ua lub luag haujlwm tseem ceeb hauv kev muab cua ua pa lossis oxygen hauv qhov chaw muaj kev phom sij. Kev xaiv cov khoom siv rau cov tank no cuam tshuam rau lawv qhov kev ua tau zoo.Carbon fiber ntau lub tog raj kheejtau dhau los ua qhov kev xaiv nrov vim lawv lub teeb yuag, siab zog, thiab kav ntev. Lawv muab cov txiaj ntsig tseem ceeb tshaj li cov tsoos hlau lossis txhuas tso tsheb hlau luam, suav nrog kev tuav tau yooj yim dua thiab txhim kho kev nyab xeeb. Kev saib xyuas tsis tu ncua thiab tuav kom raug ntawm cov tso tsheb hlau luam no kom ntseeg tau tias lawv muaj kev ntseeg siab thiab ua haujlwm tau zoo, ua rau lawv tseem ceeb rau kev nyab xeeb hauv ntau yam kev siv xwm txheej ceev thiab kev lag luam.
