Koj thaj chaw ntau npaum li cas tuaj yeem ntes tau?
Ntev npaum li cas koj lub tshuab ntes roj tuaj yeem ntes tau txoj cai?
Teb: Feem ntau cov neeg siv yuav nug cov lus nug no, ua yuam kev xav tias cov khoom siv roj tuaj yeem ntes tau ntev. Qhov tseeb, muaj kev nkag siab yuam kev ntawm no. Gas detectors, tshwj xeeb tshaj yog taag gas detectors, feem ntau yog diffused, hais tias cov roj yuav tsum tau diffuse mus rau lub sensor taub hau ntawm cov pa nrhiav kom tau cov concentration. Txwv tsis pub, txawm tias cov pa phem nyob ze, nws yuav tsis raug kuaj pom. Txhawm rau muab piv txwv yooj yim: tib neeg kev hnov tsw tsw ntxhiab yog ib qho khoom siv rhiab heev, uas tuaj yeem ntes cov pa roj carbon monoxide hauv huab cua mus rau qib siab tshaj ppb, yog li qee zaum peb yuav tsum tau ze rau nug, thiab qee zaum peb tuaj yeem hnov lawv nyob deb. deb Nws pom tau tias qhov no yog vim qhov kev taw qhia ntawm huab cua ntws thiab qhov piv ntawm cov concentrations. Cov roj yog yaj nyob rau hauv cov huab cua atmospheric. Vim tias cov cua nkag mus, nws yuav tsis raug ntes los ntawm cov khoom siv roj av ze ze. Raws li cov roj ntws mus deb ntawm cov pa xau taw tes, cov pa roj concentration yuav qis dua, yog li cov roj concentration tuaj yeem kuaj pom nyob deb. Kev nyab xeeb tsis txhais tau tias txhua qhov chaw muaj kev nyab xeeb, qhov concentration tsawg heev. Tsis muaj tus qauv nruj npaum li cas rau nruab ib qho. Tsuas yog ua ke nrog qhov xwm txheej ntawm qhov chaw tuaj yeem muab qhov chaw muaj kev phom sij raug faib kom tsim nyog. Nws raug nquahu kom nruab ib lub cuab yeej hauv thaj tsam loj ntawm 20m2, lossis nruab ib lub cuab yeej hauv thaj tsam ntawm 10-20 meters.
Dab tsi yog cov xwm txheej ib puag ncig rau kev txhim kho lub tshuab ntsuas roj?
Teb: Gas detectors txhua tus muaj lawv tus kheej ua haujlwm. Lawv tsuas yog yuav tsum tau them sai sai rau cov xwm txheej yooj yim xws li av noo, kub thiab siab. Feem ntau, nws yog qhov tsim nyog rau kev teeb tsa hauv peb lub tsev tsim khoom ib puag ncig. Yeej, lawv tuaj yeem raug ntsia ncaj qha thiab kho tau, tab sis peb Thaum txhim kho hauv qhov chaw kaw, xws li cov kav dej, lub raj xa dej, cov chaw tshwj xeeb no, peb yuav tsum tau xyuam xim kom nkag siab txog kev ua haujlwm, feem ntau ntawm peb cov khoom siv roj av, tsis hais hom twg, lawv tuaj yeem hloov kho rau cov xwm txheej, qhov kub thiab txias; -20 mus rau 50 degrees, av noo hauv qab 90 feem pua tsis muaj condensation, siab nyob rau hauv thaj tsam ntawm 100kp. Thaum tsis suav nrog cov xwm txheej ib puag ncig, nws yuav cuam tshuam qhov tseeb ntawm kev ntsuas thiab kev pabcuam lub neej ntawm lub ntsuas. Lub sijhawm no, peb yuav tsum xav txog kev ntxiv cov khoom siv roj ua ntej. Txhawm rau ua cov pa roj kom cov roj uas ua tau raws li cov xwm txheej nkag mus rau hauv lub taub hau ntawm cov roj sensor.
Puas muaj kev cuam tshuam ntawm cov plua plav ntau dhau hauv qhov chaw teeb tsa?
Teb: Cov plua plav hauv cov pa roj yog loj heev, uas yuav yooj yim ua rau cov pa hluav taws xob ntawm cov pa sensor nqus thiab ua rau txhaws, thiab qhov kev kuaj pom tseeb yuav txo qis. Yog li ntawd, ib zaug nws yog siv nyob rau hauv ib tug high-zoo plua plav puag ncig, cov plua plav yuav tsum tau lim, thiab cov plua plav yuav tsum tau ntxuav tsis tu ncua raws li cov hmoov av. Ua tib zoo tsis txhob ntxuav nws nrog dej, lossis so nrog cawv thiab lwm yam kev daws teeb meem. Ntxuav qhov chaw ntawm lub sensor tsuas yog nrog ib daim ntaub huv si.
