1. Dab tsi gases suav nrog hauv tus qauv plaub-hauv-ib?
Qee tus neeg tsis paub meej txog tus qauv plaub-hauv-ib cov pa roj thiab cov roj nrhiav kom pom ntau ntawm cov roj uas feem ntau hais tias feem pua VOL, hydrogen sulfide 0-100PPM. Haum rau siv ntau qhov chaw. Thaum cov neeg ua haujlwm nkag mus rau qhov chaw kaw, xws li cov khoom siv tshuaj tiv thaiv, cov tso tsheb hlau luam lossis cov thawv ntim khoom, cov kav dej lossis lwm cov kav dej hauv av, cov tsheb ciav hlau thauj khoom, cov khoom thauj khoom thauj khoom, qhov av, thiab lwm yam. Kev sim sab nraum qhov chaw kaw. Lub sijhawm no, ntau yam khoom siv roj av nrog cov twj tso kua mis yuav tsum tau xaiv. Vim tias cov roj faib thiab hom roj hauv ntau qhov sib txawv (sab sauv, nruab nrab thiab qis) hauv qhov chaw kaw yog qhov sib txawv heev. Feem ntau, qhov tshwj xeeb lub ntiajteb txawj nqus ntawm cov nplaim hluav taws xob yog lub teeb, thiab feem ntau ntawm lawv tau faib rau sab saud ntawm qhov chaw kaw; qhov tshwj xeeb lub ntiajteb txawj nqus ntawm carbon monoxide thiab huab cua zoo sib xws, thiab feem ntau faib nyob rau hauv nruab nrab ntawm qhov chaw kaw; thiab cov pa hnyav dua xws li hydrogen sulfide muaj nyob hauv qhov chaw kaw. qis. Nyob rau tib lub sijhawm, cov pa oxygen concentration kuj yog ib yam uas yuav tsum tau kuaj pom.
Qhov thib ob, qhov sib txawv ntawm ntuj diffusion thiab twj tso kua mis
Gas detectors txhua tus paub tias muaj ob txoj kev tshawb pom ntau tshaj plaws, ib qho yog hom diffusion thiab lwm yam yog hom twj tso kua mis, tab sis kuv tsis paub qhov txawv ntawm ob yog dab tsi. Thaum hnov ntxhiab tsw, lub tshuab nqus tsev twj siv lub twj tso kua mis self-priming kom nqus tau nws tus kheej. Piv txwv li, tib neeg lub qhov ntswg teb sai dua, yog li thaum xaiv, koj yuav tsum tau saib txoj kev tshawb nrhiav kom pom cov roj zoo.
3. Kev siv cov pa oxygen los ntsuas nitrogen yog dab tsi?
Oxygen thiab nitrogen yog cov pa roj ntau dua. Cov khoom tseem ceeb hauv huab cua yog 30% oxygen thiab 70 feem pua nitrogen. Vim yog tus nqi siab ntawm nitrogen-tseem ceeb sensors, qee cov neeg xaiv siv cov pa oxygen sensor los ntsuas nitrogen. Qhov tseeb, nws tuaj yeem siv tam sim ntawd. 100 rho tawm cov ntsiab lus ntawm cov pa oxygen yog cov ntsiab lus oxygen.
4. Puas yog lub tshuab ntes roj foob tawg?
Lub tshuab ntsuas roj nyob ntawm seb nws puas tau mus txog qib tawg-pov thawj. Cov qhab-nees tawg-pov thawj dav dav ntawm lub tshuab ntes yog BT3, BT4, thiab CT3, yog li peb tuaj yeem saib cov qib tawg-pov thawj no thaum yuav khoom thiab kuaj.
