Gas Detector yog ib qho cuab yeej cuab tam rau kev kuaj pom cov pa pa tawm, feem ntau yog xa mus rau cov khoom siv hluav taws xob thiab cov khoom siv tes tuav. Cov roj sensor feem ntau yog siv los kuaj xyuas cov roj uas muaj nyob hauv ib puag ncig. Gas sensor yog ib tug sensor siv los xyuas qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov roj.
1. Dab tsi gases suav nrog hauv tus qauv plaub-hauv-ib?
Qee tus neeg tsis paub meej txog tus qauv plaub-hauv-ib qho roj thiab qee qhov kev kuaj pom uas feem ntau tau hais. Cias muab, tus qauv plaub-hauv-ib roj yog: flammable (methane) 0-100 feem pua LEL, carbon monoxide 0-1000PPM, oxygen 0-30 feem pua VOL, hydrogen sulfide 0-100 PPM.
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 nrhiav pom, 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. Ntuj diffusion hom yog ib qho qeeb induction yam tsis muaj kev quab yuam sab nraud. Thaum nws los txog rau roj, lub twj tso kua mis suction hom 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 seb txoj kev tshawb nrhiav twg tuaj yeem ntes tau cov roj.
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 oxygen sensors 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.
Lub tshuab ntsuas roj tuaj yeem kuaj xyuas hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone thiab combustible gases thiab lwm yam gases, dav siv hauv petrochemical, thee, metallurgy, chemical kev lag luam. , municipal gas, ib puag ncig saib xyuas thiab lwm qhov chaw ntawm qhov chaw kuaj. Nws tuaj yeem ua tau raws li qhov kev xav tau ntawm lub sijhawm tshwj xeeb; nws tuaj yeem kuaj xyuas cov roj concentration lossis xau kom pom hauv qhov av, cov kav dej, tso tsheb hlau luam, qhov chaw kaw, thiab lwm yam.
