Hluav Taws Kub Ntaus: yooj yim txoj kev thiab txhais tau tias

Hluav Taws Kub sib ntaus sib tua yog ib tug txheej ntawm kev ntsuas tsom ntawm qhov hluav taws kub. Cov teeb no muaj xws li ib tug plurality ntawm txoj kev.

Lub ntsiab txoj kev hluav taws kub extinguishing - yuam tshem tawm ntawm lub ignition qhov twg los, lub txias nruab nrab thiab lub combustion ntawm ib tug roj thiab cov havzoov ntawm oxygen nyob rau hauv cov huab cua. Tag nrho cov uas yog tsim nyog los txo cov sab sauv txheej ntawm ib tug combustible cov ntaub ntawv uas ntsuas kub ntawm qhov tshem qhov tseem ceeb ntawm lub tshav kub. Txo cov feem pua ntawm cov pa yog ua los ntawm plaug mixtures ntawm inert gases los yog vapors ntawm tej yam tshuaj, thiab hluav taws extinguishing nyob rau hauv xws li ib tug cov ntaub ntawv yog nqa tawm los ntawm tseg cia cov oxidation cov tshuaj tiv thaiv ntawm combustible lub cev.

Nyob rau hauv tas li ntawd, lub thoob plaws rho tawm txoj kev combustible yeeb tshuaj, uas yog los mus tiv thaiv cov pa nkag mus rau lub oxidation tsam. Rau qhov no nws yog tsim nyog los npog lub cheeb tsam ntawm combustion extinguishing neeg sawv cev, piv txwv li, cov tshuaj lom ua npuas ncauj los yog hmoov.

Basic txoj kev extinguishing hluav taws kub kuj muaj xws li tshuaj thiab txhua yam txoj kev mus tshem tawm qhov hluav taws kub, los ntawm cov uas yog meant inhibition ntawm cov complex redox tshua thiab tam sim ntawd tshem tawm los ntawm txoj kev dav hlau ntawm dej los yog roj nyob rau hauv siab.

Hluav Taws hluav tiav thaum hluav taws kub extinguishing tshuaj (dej thiab dej vapor, xuab zeb, ua npuas ncauj, hluav taws kub extinguishing compositions thiab kuj resistant mus rau zoo xws los ntawm cov ntaub so ntswg) thiab kev lug (cranes, hydrants, hoses, twj, thiab hais txog. D.).

Xaiv ntawm daim ntawv thov ntawm cov hluav taws extinguishing tshuaj tshwm sim mloog qhov xwm thiab tsis muaj qhov hluav taws kub, lub xeev ntawm ib puag ncig thiab lub aggregation thaj chaw ntawm cov ntaub ntawv, ua hauj lwm zoo thiab cov hauj lwm zoo ntawm cov hluav taws hluav systems.

Kev chaw uas ua hluav taws sib ntaus sib tua, xws li hydrants. Qhov no ntaus ntawv rau cov dej kom tsawg los ntawm cov dej system. Hluav Taws hydrants - tag ntaus ntawv, muaj raws ntawm ib tug yeeb nkab, ib tug valve tes tsho thiab chim. Rau cia ntawm hluav taws-extinguishing neeg sawv cev yog hais txheej uas yuav tsum tau tsim kom muaj nws ua tau zoo.

Ntaus ntawm medium-qhov loj qhov hluav taws kub muaj peev xwm yuav tsim siv cov txoj kev uas extinguishing hluav taws kub, cov uas ib txwm muaj lub tua hluav taws sib txawv ntawm cov designs, raws li zoo li hluav taws cuab yeej thiab khoom. Ib suam ntawm lub tua hluav taws yog nqa tawm raws li cov hom ntawm extinguishing neeg sawv cev. Paub qhov txawv roj, ua npuas ncauj los yog hmoov.

Extinguishing lub tua hluav taws nrog roj yog nqa tawm los ntawm txoj kev cov pa roj carbon dioxide muaj pes tsawg leeg uas yog yuav tsum tau mus tua cov khib nyiab thiab cov kua. Nyob rau hauv lem, ua npuas ncauj tua hluav taws yog siv los mus tshem tawm cov combustion ntawm cov kua thiab khib nyiab. Lub disadvantage ntawm cov hluav taws xob yog hais tias lawv yuav tsis pub ua ntaub ntawv thov rau extinguishing cov ntaub ntawv, kev sis raug zoo nrog cov uas muaj peev xwm mus ua ib tug tawg. Piv txwv li, lawv yuav tsis tshem tawm qhov hluav taws kub rau hluav taws xob khoom uas yog nyob. Tua hluav taws muaj tau muab siv rau txhua lub xeev ntawm aggregation agents. Yuav ua li cas yog ib qho tseem ceeb, lawv yuav siv tau rau extinguishing hluav taws xob sib mus txog 1000 V, uas yog nyob.
