Ib hom kev ntsuas iav siv los nrhiav kom pom cov pa tawm ntawm cov pa tawm yog lub ntsuas roj. Feem ntau muaj peb hom: hom twj tso kua mis hauv online, hom twj tso kua mis, thiab hom khoom siv tes tuav. Txhawm rau txheeb xyuas hom roj uas muaj nyob hauv ib puag ncig, nws feem ntau siv lub ntsuas pa roj. Ib qho cuab yeej ntsuas siv los txiav txim seb qhov muaj pes tsawg leeg thiab cov ntsiab lus ntawm cov pa roj yog cov roj sensor.
Dab tsi gases muaj nyob rau hauv cov pa plaub-hauv-ib? Qee tus neeg tsis paub meej txog ntau yam kev tshawb nrhiav thiab cov pa roj uas lub tshuab hluav taws xob plaub-hauv-ib tuaj yeem ntes tau. Combustible EX0-100 feem pua LEL, carbon monoxide 0-1000PPM, oxygen 0 -30 feem pua VOL, thiab hydrogen sulfide 0-100PPM yog plaub gases uas ua rau plaub-hauv-ib . Piv txwv li, lub twj tso kua mis-suction hom thiab diffusion hom ntawm plaub-hauv-ib lub roj ntes ob leeg muaj los ntawm Handa Electronics. Plaub-hauv-ib lub twj tso kua mis-suction hom kev soj ntsuam cov nyhuv yog nrawm dua thiab meej dua li ob lub ntsuas ntsuas ua ke. Qhov sib npaug twj tso kua mis-suction nqi Tsis tas li ntawd, nws yog me ntsis siab dua lub diffuser.
2. Qhov sib txawv ntawm hom twj tso kua mis thiab hom diffusion Lub diffusion hom siv cov pa roj qeeb qeeb yam tsis tas siv lub zog sab nraud. Lub twj tso kua mis yog lub twj tso kua mis self-priming uas tuaj yeem nqus tau ntawm nws tus kheej. Piv txwv li, tib neeg lub qhov ntswg reacts sai dua. Yog li ntawd, thaum xaiv cov txheej txheem tshawb nrhiav, koj tuaj yeem ntes nws kom raug. gas.
3. Cov pa oxygen siv los ntsuas nitrogen li cas? Cov pa roj uas nrov tshaj yog oxygen thiab nitrogen. Oxygen thiab nitrogen yog ob lub ntsiab tseem ceeb hauv huab cua. Cov ntsiab lus nitrogen yog 78.09 feem pua, hos cov ntsiab lus oxygen yog 20.95 feem pua. Qee cov neeg siv yuav ua yam tsis muaj nitrogen tshwj xeeb sensors vim lawv cov nqi sib piv. Nws tuaj yeem xaiv los ntsuas nitrogen siv lub ntsuas pa oxygen, qhov twg koj yuav txiav tawm cov ntsiab lus oxygen los ntawm 100, uas yog cov ntsiab lus oxygen.
4. Puas yog lub tshuab ntes roj tiv thaiv kev tawg? Txawm hais tias nws tau ua tiav qhov kev ntsuas tawg-pov thawj yuav txiav txim siab lub ntsuas roj. Peb xav txog cov kev ntsuam xyuas tawg-pov thawj no thaum yuav lub tshuab kuaj xyuas vim tias lawv yog cov qib kev tawg-pov thawj: BT3, BT4, CT3, CT6, thiab lwm yam. Gas detector feem ntau yog siv rau hauv petrochemical, thee, metallurgy, tshuaj lom neeg kev lag luam, roj hauv nroog, kev saib xyuas ib puag ncig, thiab lwm qhov chaw ntawm qhov chaw kuaj. Nws tuaj yeem kuaj xyuas hydrogen sulfide, carbon monoxide, oxygen, sulfur dioxide, phosphine, ammonia, nitrogen dioxide, hydrogen cyanide, chlorine, chlorine dioxide, ozone, thiab cov roj hluav taws xob ntawm lwm cov roj. Nws tuaj yeem kuaj xyuas cov pa roj los yog kev kuaj pom hauv qhov tunnels, pipelines, tso tsheb hlau luam, thiab lwm qhov chaw kaw, nrog rau kev ntsuas qhov xav tau ntawm lub sijhawm tshwj xeeb.
