Dab tsi ntawm cov roj ntes tau siv rau hauv cov ntawv thov
Raws li peb txhua tus paub, kev tshawb nrhiav roj rau kev tiv thaiv kev nyab xeeb, yog qhov tsim nyog heev rau kev ua haujlwm, lub tshuab ntsuas roj nws tuaj yeem ua tau zoo kom paub tseeb tias qhov chaw txwv tsis pub siv roj pom, kom muaj kev nyab xeeb ntawm qhov chaw. Txawm li cas los xij, vim muaj qhov sib txawv ntawm daim ntawv thov, cov khoom siv hluav taws xob tam sim no kuj muaj ntau dua, nws tuaj yeem raug faib raws li cov kev faib tawm sib txawv ntawm ntau lub tshuab ntsuas roj. Yog li koj puas paub dab tsi yog cov kev faib ua feem ntawm cov roj ntes?
Gas Detector Common Classification:
1, raws li kev faib ua haujlwm:
Muaj ib lub tshuab ntes ib leeg thiab ntau lub tshuab ua haujlwm: ib lub tshuab hluav taws xob nkaus xwb rau kev tshawb nrhiav cov roj hauv qhov chaw tshawb nrhiav, kev siv ntau heev. Multi-function gas detector muaj 6-hauv-ib gas detector, tsib-hauv-ib gas detector, plaub-hauv-ib gas detector, thiab lwm yam.
2, raws li kev txheeb xyuas ntawm kev faib roj:
Muaj cov khoom siv hluav taws xob hluav taws xob, lub tshuab hluav taws xob muaj kuab paug, cov khoom siv roj hluav taws xob, cov khoom siv hluav taws xob tshwj xeeb; uas feem ntau combustible thiab toxic gas detection instrument nqi feem ntau yog li ntawm ob peb puas mus rau ob peb txhiab, thaum lub sij hawm tus nqi ntawm cov khoom siv tshwj xeeb uas muaj roj nrhiav kom tau yog nyob rau hauv lub phav phav ntawm kaum tawm txhiab qhov sib txawv. Qhov zoo ntawm cov khoom siv tshuaj tua hluav taws thiab tshuaj lom neeg muaj txiaj ntsig zoo yog cov txiaj ntsig zoo, kev ua haujlwm zoo, thaum cov roj tshwj xeeb kom ua tau raws li qhov xav tau tshwj xeeb tshuaj xyuas thiab qhov raug siab, tab sis kim.
3, raws li kev siv qhov chaw faib khoom:
Hom pa thiab tawg-pov thawj: hom pa yog ua raws li lub teb chaws cov qauv tsim los ua kom tau raws li qhov xav tau ntawm txhua qhov kev siv ib puag ncig, tus nqi ntawm ntau pua mus rau txhiab tus, tus cwj pwm los ntawm kev ua haujlwm zoo heev. Hom tawg-pov thawj kom tau raws li qhov xav tau ntawm cov chaw tshwj xeeb yuav tsum tau kuaj, tus nqi yog me ntsis kim dua.
4, raws li kev siv ntawm pawg neeg pawg:
Hauv tsev thiab kev lag luam: cov khoom siv hluav taws xob hauv tsev cov nqi hauv kaum mus rau pua pua ntawm yuan, tus nqi tsim nyog thiab siv tau yooj yim, tsuas yog yuav tsum tau tswj qhov kev tso kawm nyob rau hauv qhov chaw xaiv los ntxig rau cov khoom siv hluav taws xob tuaj yeem ua haujlwm, thiab tuaj yeem txuas rau kev txiav tawm. gas valve kom ua tiav automated ua, yuav muab zais los ntawm qhov chaw ntawm kev txiav tawm. Cov ntsuas hluav taws xob muaj hluav taws xob muaj siab heev, yuav tsum ua kom tau raws li lub teb chaws cov qauv thiab cov qauv thiab lwm qhov chaw siv ntau hom kev nyab xeeb thiab cov qauv, cov nqi ntawm ob peb puas mus rau ob peb txhiab.
5, raws li kev siv kev faib tawm:
Muaj cov khoom siv nqa tau (lub tes tuav) thiab ruaj khov (mounted, phab ntsa-mounted): portable kom tau raws li qhov chaw tus neeg teb xov tooj lub chaw ua haujlwm ua ntej kev nyab xeeb nrhiav pom cov twj paj nruag, feem ntau cuam tshuam nrog kev siv ntawm qhov chaw. Cov hom ruaj khov yog tsuas yog ua kom tiav lub sijhawm ntev tsis muaj kev cuam tshuam kev tshawb nrhiav, txhawm rau tiv thaiv kev nyab xeeb ntawm thaj chaw, tsis tas yuav tsum muaj kev tswj hwm ntawm cov neeg ua haujlwm hauv tsev, thiab tuaj yeem tsim kev sib txuas ntse.
6, raws li cov qauv kev faib tawm:
Muaj diffusion thiab twj tso kua mis: diffusion gas detector siv ntau heev, tus nqi kuj qis los ntawm ob peb puas mus rau ob peb txhiab daus las. Lub twj tso kua mis nqus roj ntes tus nqi yog tus nqi siab, feem ntau yog ntau tshaj li ob peb txhiab, feem ntau ua tau raws li cov kev xav tau tshwj xeeb ntawm cov chaw tshwj xeeb.
7, raws li kev txheeb xyuas txoj cai kev faib tawm:
Combustible gas detection catalytic combustion type, semiconductor type, thermal conductivity thiab infrared absorption type, thiab lwm yam; toxic gas detection electrochemical yam, semiconductor type.
