Dab tsi yog Daim Ntawv Thov Tseem Ceeb ntawm Gas Detectors?
1. Classified los ntawm kev ua haujlwm:
Muaj cov khoom siv roj ib leeg thiab cov khoom siv ntau yam: cov khoom siv roj ib leeg yog siv los tshawb xyuas qee cov roj hauv qhov chaw tshawb nrhiav, thiab kev siv loj heev. Lub multifunctional gas detector muaj xws li rau hauv ib tug gas detector, tsib nyob rau hauv ib tug gas detector, plaub nyob rau hauv ib tug gas detector, thiab Couric gas detector, uas ua tau raws li cov kev xav tau ntawm txawv roj nrhiav kom muaj nuj nqis.
2. Muab cais los ntawm kev kuaj pom roj:
Muaj cov khoom siv roj hluav taws xob, cov khoom siv tshuaj lom neeg, cov khoom siv roj ntsha, thiab cov khoom siv roj tshwj xeeb; Tus nqi ntawm cov khoom siv tshuaj tua hluav taws thiab tshuaj lom tshuaj lom neeg feem ntau yog los ntawm ob peb puas mus rau ob peb txhiab, thaum cov nqi ntawm cov cuab yeej tshwj xeeb nrhiav kom pom cov pa roj ntau ntawm ntau txhiab mus txog kaum txhiab. Qhov zoo ntawm cov khoom siv tshuaj tua hluav taws thiab tshuaj lom tshuaj lom neeg yog cov nqi siab -kev ua tau zoo thiab kev ua haujlwm zoo, thaum cov pa roj tshwj xeeb ua tau raws li qhov xav tau tshwj xeeb tshuaj xyuas thiab muaj qhov raug siab, tab sis kim heev.
3. Muab faib raws qhov chaw siv:
Muaj cov pa thiab tawg- cov ntaub ntawv pov thawj: hom pa yog tsim raws li lub teb chaws tus qauv kom tau raws li tag nrho cov kev xav tau ntawm ib puag ncig, nrog rau cov nqi ntawm ob peb puas mus rau ob peb txhiab, thiab tus yam ntxwv yog tus nqi zoo heev -effectiveness. Cov ntaub ntawv pov thawj tawg ua tau raws li qhov kev xav tau ntawm cov chaw tshwj xeeb thiab yog me ntsis kim dua.
4. Muab faib los ntawm pawg neeg siv:
Rau kev siv hauv tsev thiab kev lag luam: Tus nqi ntawm cov khoom siv hluav taws xob hauv tsev yog li ntawm kaum rau ntau pua yuan, nrog rau tus nqi zoo heev -kev ua tau zoo thiab siv tau yooj yim. Lawv tsuas yog yuav tsum tau muab tso rau hauv qhov chaw xaiv thiab ntsaws rau hauv lub zog hluav taws xob los ua haujlwm, thiab tuaj yeem txuas nrog lub tshuab hluav taws xob txiav tawm -off valve kom ua tiav kev ua haujlwm tsis siv neeg thiab txiav cov kev phom sij zais ntawm qhov chaw. Cov khoom siv roj av muaj cov kev xav tau siab heev rau ntau yam ntsuas thiab yuav tsum ua kom tau raws li cov qauv kev nyab xeeb xws li cov qauv kev lag luam hauv teb chaws thiab kev lag luam rau ntau qhov chaw. Tus nqi ntawm ntau pua mus rau ntau txhiab yuan.
5. Muab faib los ntawm kev siv:
Muaj cov cuab yeej nqa tau (lub tes tuav) thiab ruaj khov (nruab, phab ntsa mounted) cov cuab yeej: cov cuab yeej nqa tau yooj yim uas ua tau raws li kev nyab xeeb ntawm - cov neeg ua haujlwm rau kev kuaj xyuas cov pa roj ua ntej ua haujlwm, feem ntau nyob ntawm qhov kev siv scenario. Hom kev ruaj khov feem ntau ua tiav ntev - lub sij hawm tsis cuam tshuam kev tshawb nrhiav kom ntseeg tau tias muaj kev nyab xeeb ntawm lub xaib, tsis tas yuav tsum muaj rau ntawm - cov neeg ua haujlwm tswj hwm qhov chaw, thiab tuaj yeem txuas tau ntse.
6. Muab faib los ntawm txoj kev sampling:
Muaj hom diffusion thiab twj tso kua mis hom roj ntes: diffusion hom roj ntes tau siv dav thiab muaj tus nqi qis txij li ob peb puas yuan mus rau ntau txhiab yuan. Tus nqi ntawm lub twj tso kua mis nqus roj ntes yog tus nqi siab, feem ntau yog li ntawm ob peb txhiab yuan lossis ntau dua, feem ntau ua kom tau raws li qhov xav tau tshwj xeeb ntawm qhov chaw tshwj xeeb.
7. Muab faib los ntawm kev tshawb nrhiav txoj cai:
Kev kuaj pom cov roj hluav taws xob muaj xws li catalytic combustion hom, semiconductor hom, thermal conductivity hom, thiab infrared absorption hom; Kev kuaj pom cov pa phem muaj xws li electrochemical thiab semiconductor hom.
