Kev nkag siab zoo ntawm lub tshuab ntsuas roj hauv lub neej txhua hnub?
Gas Detector yog ib qho cuab yeej siv los ntsuas cov pa xau concentration. Feem ntau, muaj peb hom: handheld diffusion hom, twj tso kua mis hom thiab tsau hom on-line. Nws tsuas yog siv cov roj sensors los kuaj xyuas cov roj gas uas muaj nyob hauv ib puag ncig. Gas sensors yog siv los kuaj xyuas qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov cuab yeej ntsuas cov pa, tom qab ntawd qhov kev nkag siab zoo hauv lub neej niaj hnub ntawm lub ntsuas roj?
1. Cov pa roj dab tsi suav nrog hauv tus qauv 4-hauv-1?
Qee tus neeg tsis paub tias cov pa roj twg thiab qhov kev tshawb nrhiav ntau ntawm plaub-hauv-ib lub tshuab nqus roj feem ntau tau hais. Cias muab, plaub gases nyob rau hauv plaub-hauv-ib yog: flammable EX0-100 feem pua LEL, carbon monoxide 0-1000PPM, oxygen 0 -30 feem pua VOL, hydrogen sulfide 0-100 PPM.
Piv txwv li, Handa Electronics muaj ob lub tshuab hluav taws xob plaub-hauv-ib, uas yog hom twj tso kua mis thiab hom diffusion. Piv nrog rau ob lub detectors, lub twj tso kua mis suction plaub-nyob rau hauv-ib gas detection nyhuv yog sai dua thiab raug dua. Tus nqi twj tso kua mis sib txuas Nws kuj yog me ntsis siab dua li hom diffusion;
Qhov thib ob, qhov sib txawv ntawm diffusion thiab twj tso kua mis?
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. Cov roj tau hnov, thiab lub twj tso kua mis-suction hom siv lub twj tso kua mis tus kheej 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 roj zoo;
3. Kev ntsuas pa rov qab ntawm nitrogen Oxygen thiab nitrogen cov pa roj?
Cov khoom tseem ceeb hauv huab cua yog oxygen thiab nitrogen, cov ntsiab lus: cov ntsiab lus oxygen yog 20.95 feem pua, thiab cov ntsiab lus nitrogen yog 78.09 feem pua. Vim yog tus nqi siab ntawm cov khoom siv nitrogen tshwj xeeb, qee cov neeg yuav xaiv siv cov pa oxygen sensors los ntsuas nitrogen rov qab, uas yog qhov ua tau, uas yog, siv 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 qib tawg-pov thawj dav dav ntawm lub tshuab ntes yog BT3, BT4, CT3, CT6, thiab lwm yam, yog li thaum peb yuav lub tshuab ntes, peb tsuas yog yuav tsum saib cov qib tawg-pov thawj no.
Gas detector tuaj yeem ntes 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 nyob rau hauv petrochemical, thee nrhiav pom nyob rau hauv lub site. Ntau qhov chaw xws li metallurgy, tshuaj lom neeg kev lag luam, roj hauv nroog, thiab kev saib xyuas ib puag ncig tuaj yeem ua tau raws li qhov xav tau ntawm kev ntsuas tshwj xeeb; nws tuaj yeem kuaj xyuas cov roj concentration lossis xau kom pom hauv qhov av, kav dej, tso tsheb hlau luam, thiab qhov chaw kaw.
