Dab tsi yog hom roj ntes siv hauv kev siv
1. Classified los ntawm kev ua haujlwm:
Muaj ib lub tshuab ntes thiab ntau lub tshuab ntes: Ib qho roj av ntes tau tsuas yog siv los ntes qee cov roj hauv qhov chaw tshawb nrhiav, thiab nws tau siv dav heev. Thiab multifunctional gas detectors suav nrog 6-hauv-1 gas detectors, 5-hauv-1 gas detectors, 4-hauv-1 gas detectors, thiab lwm yam., kom ua tau raws li qhov xav tau ntawm qhov sib txawv ntawm qhov ntsuas roj.
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 nyob ntawm ob peb puas mus rau ob peb txhiab, thaum tus nqi ntawm cov cuab yeej tshawb nrhiav roj tshwj xeeb yog nyob ntawm ntau txhiab mus rau kaum txhiab. Qhov zoo ntawm cov khoom siv tshuaj tua hluav taws thiab tshuaj lom tshuaj lom neeg yog cov nqi-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 lawv kim heev.
3. Muab faib los ntawm qhov chaw siv:
Muaj cov pa thiab tawg-pov thawj hom: cov pa hom yog tsim raws li lub teb chaws tus qauv thiab muaj peev xwm ua tau raws li tag nrho cov kev xav tau ntawm ib puag ncig, nrog rau cov nqi xws li ib tug ob peb puas mus rau ob peb txhiab, tus yam ntxwv ntawm zoo heev nqi-zoo. Hom tawg-pov thawj ua tau raws li txhua qhov kev xav tau ntawm cov chaw tshwj xeeb thiab yog kim me ntsis.
4. Muab faib los ntawm pawg neeg siv:
Muaj cov ntawv thov hauv tsev thiab kev lag luam: Cov cuab yeej siv hluav taws xob hauv tsev raug nqi ntawm kaum rau ntau pua yuan, nrog rau cov nqi zoo thiab siv tau yooj yim. Lawv tsuas yog yuav tsum tau muab tso rau hauv cov haujlwm uas tau teev tseg thiab ntsaws rau hauv cov khoom siv hluav taws xob kom ua haujlwm tau zoo. Lawv kuj tseem tuaj yeem txuas nrog cov roj hluav taws xob kaw kom ua tiav qhov kev ua haujlwm tsis siv neeg thiab txiav cov kev phom sij zais ntawm qhov chaw. Cov kev cai rau ntau yam kev ntsuas ntawm kev lag luam roj av detectors yog siab heev, thiab lawv yuav tsum ua kom tau raws li cov cai kev nyab xeeb thiab cov qauv siv nyob rau hauv ntau qhov chaw xws li cov qauv hauv teb chaws thiab cov qauv kev lag luam, nrog rau cov nqi ntawm ob peb puas mus rau ntau txhiab yuan.
5. Muab faib los ntawm kev siv:
Muaj cov khoom siv nqa tau (lub tes tuav) thiab ruaj khov (nruab, phab ntsa mounted): cov cuab yeej nqa tau yooj yim uas ua tau raws li kev nyab xeeb ntawm cov neeg ua haujlwm hauv chaw rau kev tshawb nrhiav roj ua ntej ua haujlwm, feem ntau cuam tshuam nrog kev siv scenario. Cov hom ruaj khov feem ntau ua tiav qhov kev tshawb nrhiav tsis muaj kev cuam tshuam ntev los xyuas kom muaj kev nyab xeeb ntawm lub xaib, tsis tas yuav tsum muaj kev tswj hwm ntawm cov neeg ua haujlwm hauv tsev, thiab tuaj yeem txuas tau ntse.
6. Kev faib tawm los ntawm kev ua piv txwv:
Muaj hom diffusion thiab twj tso kua mis hom: diffusion hom gas detectors muaj ib tug heev siv tus nqi thiab kuj tsis tshua muaj nqi, xws li los ntawm ob peb puas mus rau ob peb 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 tshwj xeeb xav tau ntawm cov chaw zoo tib yam.
7. Muab faib los ntawm cov qauv kev tshawb nrhiav:
Kev tshawb pom cov roj hluav taws xob muaj xws li catalytic combustion hom, semi conductive type, thermal conductivity type, thiab infrared absorption type, thiab lwm yam; Kev kuaj pom muaj pa phem tuaj yeem yog electrochemical, semiconductor, thiab lwm yam.
