Dab tsi yog Pressurized Water Based Fire Extinguisher haum rau tuav?
Raws li peb txhua tus paub, kev sib tsoo hluav taws tuaj yeem ua rau muaj kev puas tsuaj loj rau cov cuab yeej thiab ua rau lub cev raug mob hnyav lossis txawm tias muaj neeg tuag. Yog li ntawd, nws yog ib qho tseem ceeb kom muaj kev tiv thaiv hluav taws nyob rau hauv qhov chaw. Ib qho ntawm cov cuab yeej tseem ceeb rau kev tiv thaiv hluav taws yog lub tshuab tua hluav taws. Muaj ntau ntau hom kev tua hluav taws hauv kev ua lag luam, thiab txhua tus muaj nws qhov tshwj xeeb thiab tsim nyog.
Nyob rau hauv tsab xov xwm no, peb yuav tsom mus rau cov dej siab raws li kev tua hluav taws - nws muaj pes tsawg leeg, qhov zoo, kev txwv, thiab kev tsim nyog rau kev tuav ntau hom hluav taws.
Kev sib xyaw
Raws li lub npe qhia, cov tshuaj tua hluav taws uas muaj cov tshuaj tua hluav taws muaj cov dej ua tus thawj tua hluav taws. Cov dej hauv lub tshuab tua hluav taws tuaj yeem yog cov ntshiab los yog tov nrog ntau yam tshuaj ntxiv los txhim kho nws cov txiaj ntsig. Piv txwv li, dej sib xyaw nrog AFFF (Aqueous Film Forming Foam) yog qhov tsim nyog rau kev tua hluav taws los ntawm cov kua hluav taws xob xws li roj av, roj av, thiab cov kuab tshuaj.
Sib nrug los ntawm cov dej thiab cov khoom siv ntxiv, cov dej siab raws li hluav taws xob tua hluav taws kuj tseem muaj cov pa roj nitrogen ua lub zog. Cov roj nitrogen yog khaws cia rau hauv ib qho chaw sib cais thiab yog siv los tshem tawm cov dej los ntawm lub nozzle thaum siv.
Qhov zoo
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv hluav taws xob los ntawm cov hluav taws kub yog nws cov txiaj ntsig zoo. Piv nrog rau lwm hom hluav taws tua hluav taws, xws li CO2 thiab halon extinguishers, cov dej tua hluav taws kuj tseem pheej yig los yuav thiab tswj.
Lwm qhov kom zoo dua ntawm cov dej siab raws li hluav taws xob tua hluav taws yog nws qhov ua tau zoo hauv kev tuav cov hluav taws hauv chav kawm A. Cov hluav taws kub hauv chav kawm A suav nrog cov hluav taws kub uas tshwm sim los ntawm cov khoom siv hluav taws xob xws li ntoo, ntawv, thiab textiles. Dej yog ib qho zoo kawg nkaus extinguishing tus neeg sawv cev rau chav kawm A hluav taws kub thaum nws txias qhov hluav taws kub qhov chaw roj mus rau hauv qab nws ignition point.
Tsis tas li ntawd, cov dej tua hluav taws yog ib puag ncig zoo. Tsis zoo li lwm cov tshuaj tua hluav taws uas muaj cov tshuaj phem xws li halon, cov tshuaj tua hluav taws kub uas muaj dej kub tsis ua rau muaj kev puas tsuaj rau ib puag ncig.
Kev txwv
Txawm hais tias nws qhov txiaj ntsig zoo, cov hluav taws kub hnyiab uas siv hluav taws kub muaj qee qhov kev txwv. Ib qho ntawm cov kev txwv tseem ceeb yog nws tsis tsim nyog rau kev tuav cov hluav taws kub los ntawm cov kua hluav taws xob thiab hluav taws xob hluav taws xob.
Dej yog cov khoom siv hluav taws xob, txhais tau tias nws tuaj yeem ua rau hluav taws xob poob lossis hluav taws xob yog siv hluav taws xob hluav taws xob. Yog li ntawd, nws yog ib qho tseem ceeb los xyuas kom meej tias cov hluav taws xob tua hluav taws siv hluav taws xob tsis yog hluav taws xob.
Lwm qhov kev txwv ntawm cov hluav taws kub hauv cov dej kub yog lawv qhov hnyav. Dej yog ib yam khoom hnyav, thiab cov tshuaj tua hluav taws uas muaj zog tuaj yeem ua rau muaj kev nyuaj siab, tshwj xeeb tshaj yog rau cov neeg laus lossis cov neeg tsis taus.
Haum rau kev tuav ntau hom hluav taws kub
Cov tshuaj tua hluav taws uas muaj cov dej kub uas yog siv rau kev siv hluav taws kub hauv chav kawm A, raws li tau hais ua ntej. Cov hluav taws kub hauv chav A feem ntau suav nrog cov khoom siv hluav taws xob, xws li ntoo, ntawv, thiab textiles.
Sib nrug los ntawm cov hluav taws kub hauv chav A, cov hluav taws kub kub uas siv hluav taws xob siv hluav taws xob kuj tseem tsim nyog rau kev siv hluav taws kub hauv Class F. Cov hluav taws kub hauv chav F suav nrog cov roj ua noj thiab roj thiab feem ntau tshwm sim hauv chav ua noj thiab tsev noj mov. Cov dej sib xyaw nrog AFFF muaj txiaj ntsig zoo hauv kev tua hluav taws hauv chav F.
Txawm li cas los xij, cov tshuaj tua hluav taws kub uas muaj cov dej kub tsis haum rau kev tua hluav taws hauv chav B thiab Class C. Cov hluav taws kub hauv chav kawm B suav nrog cov kua hluav taws xob xws li roj av, diesel, thiab cov kuab tshuaj. Cov dej tua hluav taws tsis haum rau cov hluav taws kub hauv chav B vim tias cov dej tuaj yeem kis tau hluav taws, ua rau qhov xwm txheej tsis zoo.
Cov hluav taws kub hauv chav kawm C suav nrog cov khoom siv hluav taws xob. Raws li tau hais ua ntej, cov dej tua hluav taws tsis haum rau hluav taws xob hluav taws xob.
Xaus
Cov tshuaj tua hluav taws kub uas muaj dej siab yog cov cuab yeej tiv thaiv hluav taws uas muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo thaum siv kom tsim nyog. Nws qhov kev tsim nyog nyob ntawm seb hom hluav taws kub raug tuav. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum xaiv cov khoom tua hluav taws zoo raws li qhov muaj feem cuam tshuam txog hluav taws.
Thaum kawg, kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas lub tshuab tua hluav taws yog qhov tseem ceeb los xyuas kom meej tias nws ua haujlwm zoo thaum twg xav tau.
