Cov teeb meem xav tau kev saib xyuas thaum kuaj pom cov pa roj
Gas Detector yog ib qho cuab yeej cuab tam rau kev kuaj pom cov pa tawm, feem ntau yog xa mus rau cov khoom siv hluav taws xob thiab cov khoom siv tes tuav. Gas sensors feem ntau yog siv los xyuas cov hom roj av uas muaj nyob hauv ib puag ncig. Gas sensors yog cov sensors siv los ntsuas qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm gases.
1. Dab tsi gases muaj nyob rau hauv tus qauv plaub-hauv-ib
Qee tus neeg tsis paub meej txog tus qauv plaub-hauv-ib qho roj thiab qee qhov kev tshawb pom ntawm cov pa roj uas feem ntau hais. Cias muab, tus qauv plaub-hauv-ib roj: flammable (methane) 0-100 feem pua LEL, carbon monoxide 0-1000PPM, oxygen 0-30 feem pua VOL, hydrogen sulfide 0-100PPM .
2. Qhov sib txawv ntawm ntuj diffusion hom thiab twj tso kua mis hom
Gas detectors paub tias muaj ob txoj kev tshawb pom ntau tshaj plaws, ib qho yog hom diffusion ntuj thiab lwm yam yog hom twj tso kua mis, tab sis kuv tsis paub qhov txawv ntawm ob yog dab tsi. Lub ntuj diffusion hom yog qeeb yam tsis siv lwm lub zog. Gas yog hnov, thiab 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 saib txoj kev tshawb nrhiav kom pom cov pa zoo.
3. Dab tsi yog qhov rov qab ntsuas ntawm nitrogen nrog oxygen
Oxygen thiab nitrogen yog cov pa roj ntau. Cov khoom tseem ceeb hauv huab cua yog 30% oxygen thiab 70 feem pua nitrogen. Vim tias tus nqi ntawm nitrogen-specific sensors kuj yog siab, qee cov neeg yuav xaiv siv cov pa oxygen sensors los ntsuas nitrogen rov qab, uas yog qhov ua tau. 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 tsuas yog yuav tsum tau saib cov qib tawg-pov thawj no thaum peb yuav qhov kev xeem.
