Basic Knowledge Analysis of Combustible Gas Detectors
Daim ntawv thov tam sim no ntawm kev tshawb nrhiav roj siv thev naus laus zis tau dhau los ua qhov dav, tsis yog tsuas yog xav kom nws dhau ntawm lwm cov khoom tshawb nrhiav hauv cov ntsiab lus ntawm kev siv thev naus laus zis, tab sis kuj maj mam ua qhov hnyav hauv kev siv thiab ua haujlwm. Gas detectors loj heev thiab tsis yooj yim rau siv. Txhawm rau kom yooj yim txav tau thiab siv tau, cov khoom siv hluav taws xob portable tau ua ntau dua thiab zoo meej. Portable gas detectors tam sim no tau muab faib ua ob hom: twj tso kua mis thiab diffusion.
Lub twj tso kua mis hom roj ntes tau nruab nrog lub twj tso kua mis me me, uas ua haujlwm los ntawm kev tsav lub hwj chim coj mus kuaj cov roj hauv cheeb tsam yuav tsum tau kuaj, thiab tom qab ntawd xa cov qauv roj mus rau qhov ntsuas ntsuas. Tus yam ntxwv ntawm lub twj tso kua mis nqus roj ntes yog nws qhov kev tshawb nrhiav ceev ceev, uas tso cai rau kev ntsuas thaj tsam ntawm thaj chaw txaus ntshai, tswj cov neeg ua haujlwm nyab xeeb, thiab zoo ib yam li diffusion hom gas detector.
Lub diffusive gas detector yog siv los kuaj xyuas cov pa dawb ntws hauv qhov chaw kuaj pom thiab qeeb ntawm cov qauv roj mus rau hauv qhov ntsuas. Txoj kev no yog cuam tshuam los ntawm kev tshawb nrhiav ib puag ncig, xws li ambient kub, airflow, thiab lwm yam. Cov yam ntxwv ntawm diffusion hom gas detector yog nws cov nqi qis.
Lub hauv paus ntsiab lus ntawm kev ua hauj lwm ntawm lub twj tso kua mis suction hom thiab diffusion hom gas detectors yog yeej ib yam. Cov qauv roj raug kuaj pom los ntawm qhov ntsuas qhov ntsuas thiab tom qab ntawd nthuav dav thiab hloov mus rau cov lej sib raug zoo rau kev tso saib ntawm qhov screen. Lub portable gas detectors tsim los ntawm Huarui Group hauv Tebchaws Meskas muaj ntau hom, me me, kev ua haujlwm yooj yim, thiab siv tau yooj yim. Lawv muaj peb lub tswb ceeb toom: suab, lub teeb, thiab kev co, uas tuaj yeem ua tau raws li qhov xav tau ntawm ntau qhov chaw hauv kev lag luam.
Gas detectors muab kev yooj yim rau ntau yam kev lag luam xws li kev lag luam thiab mining, thiab tuaj yeem kuaj xyuas qhov kev nyab xeeb ntawm ib puag ncig kev tsim kho. Xyuas kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thaum tsim kho.
