Ntev npaum li cas koj lub tshuab ntes roj tuaj yeem ntes tau?
Ntev npaum li cas koj lub tshuab ntes roj tuaj yeem ntes tau? Cov neeg siv feem ntau 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 diffuse, uas txhais tau hais tias cov pa Diffusion yuav tsum tau mus rau lub gas detection taub hau rau lawv mus ntes 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 yog ib qho rhiab heev hauv nruab nrog cev thiab tuaj yeem tshawb pom cov pa roj carbon monoxide hauv huab cua xws li cov lej ntawm cov lej mus rau qib ppb. Qee lub sij hawm peb yuav tsum tau nyob ze heev txhawm rau txheeb xyuas lawv, thiab qee zaum peb tuaj yeem hnov lawv nyob deb. Yog li, qhov no yog vim qhov kev taw qhia ntawm huab cua ntws thiab concentration ratio. Gases yaj nyob rau hauv atmospheric huab cua tej zaum yuav tsis raug ntes los ntawm cov khoom siv tshuaj ntsuam xyuas cov pa ze ze vim yog cua kev taw qhia. 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 raug kuaj pom ntawm qhov deb. Kev nyab xeeb tsis tau txhais hais tias txhua qhov chaw muaj kev nyab xeeb thiab cov concentration tsawg heev. Tsis muaj tus qauv nruj rau kev txhim kho ib qho ntawm qhov ze tshaj plaws. Tsuas yog qhov chaw ntawm qhov chaw muaj kev phom sij tuaj yeem raug faib raws li cov xwm txheej ntawm qhov chaw. Nws raug nquahu kom nruab ib qho hauv thaj tsam ntawm 20m2, lossis rau 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?
Gas detectors txhua tus muaj lawv tus kheej ua hauj lwm tej yam kev mob uas lawv hloov. Peb tsuas yog yuav tsum tau them sai sai rau qhov yooj yim ntawm cov av noo, kub thiab siab. Feem ntau, lawv tsim nyog rau kev teeb tsa hauv peb cov chaw ua haujlwm ib puag ncig. Yeej, lawv tuaj yeem ntsia tau thiab kho ncaj qha, tab sis peb nruab rau hauv qhov chaw kaw, xws li cov kav dej thiab cov hluav taws xob, hauv qhov 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 kom haum rau qhov kub thiab txias; -20 mus rau 50 degrees, av noo hauv qab 90% tsis muaj condensation, siab hauv 100kp. Thaum cov xwm txheej ib puag ncig tsis nyob ntawm no, nws yuav cuam tshuam rau 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 khoom siv roj, cia cov roj uas ua tau raws li cov xwm txheej nkag mus rau lub taub hau ntawm lub taub hau.
Puas yuav muaj kev cuam tshuam yog tias qhov chaw teeb tsa muaj plua plav dhau lawm?
Yog tias cov plua plav hauv cov pa loj dhau lawm, nws yuav yooj yim ua rau cov pa hluav taws xob ntawm cov pa sensor yuav adsorbed thiab thaiv, thiab qhov kev kuaj pom tseeb yuav txo qis. Yog li ntawd, ib zaug siv nyob rau hauv ib puag ncig cov plua plav siab, cov plua plav yuav tsum tau lim thiab cov plua plav yuav tsum tau ntxuav tsis tu ncua nyob ntawm cov hmoov av. Nco ntsoov tsis txhob ntxuav nws nrog dej lossis so nrog cawv lossis lwm yam tshuaj. Tsuas yog siv ib daim ntaub huv, mos los ntxuav lub sensor nto.
