Cov kev xaiv uas thaiv yog qhov tseem ceeb thaum nws los txog kom ntseeg tau qhov kev nyab xeeb ntawm cov chaw muaj kev nyab xeeb, tshwj xeeb ntau yam kev puas tsuaj. Cov chaw muaj kev phom sij yog tsim los los tiv thaiv cov khoom siv hluav taws xob los ntawm cov roj hluav taws xob uas tawg tau, hmoov av thiab lwm qhov chaw ib puag ncig. Cov lus qhia no yuav pab koj mus nrhiav cov nyom ntawm kev xaiv aThaj tsam muaj kev phom sijQhov ntawd yog rau koj cov kev xav tau tshwj xeeb.
Nkag siab txog thaj chaw txaus
Ua ntej ntsag rau hauv cov txheej txheem xaiv, nws yog qhov tsim nyog kom nkag siab txog dab tsi yog thaj chaw muaj kev phom sij. Cov chaw no tau faib ua ke raws li muaj cov pa roj av uas muaj cov pa hluav taws, vapors lossis hmoov av. Cov khoos kas cov tshuab feem ntau suav nrog:
- Thaj Chaw 0: Ib qho chaw uas ib puag ncig hluav taws xob uas tawg tsis tu ncua lossis ntev ntev.
- Tsam 1: Thaj chaw uas cov huab cua tawg yuav tshwm sim thaum lub sijhawm ua haujlwm ib txwm muaj.
- Zone 2: Lub chaw ua pa roj tawg tsis zoo li yuav tshwm sim thaum lub sijhawm ua haujlwm ib txwm muaj, thiab yog tias nws ua, nws yuav tsuas muaj rau lub sijhawm luv luv.
Txhua Cheeb Tsam yuav tsum muaj hom kev sib txuas tshwj xeeb kom muaj kev nyab xeeb thiab ua raws li cov kev cai.
Cov kev txiav txim siab tseem ceeb hauv kev xaiv thaj chaw muaj kev phom sij
1. Cov khoom siv xaiv
Cov khoom ntawm rooj plaub yog qhov tseem ceeb rau kev ua kom ntev thiab kev nyab xeeb. Cov Khoom Siv Uas Muaj:
- Stainless hlau: Muab cov tshuaj tiv thaiv corrosion zoo heev, zoo tagnrho rau kev hnyav ib puag ncig.
- Tooj dawb: Lub teeb yuag thiab corrosion-resistant, tab sis yuav tsis haum rau txhua thaj chaw muaj kev phom sij.
- Polycarbonate: Muab kev cuam tshuam zoo tsis kam thiab feem ntau siv nyob rau hauv ib puag ncig hnyav.
Xaiv cov khoom yog yuav nyob ntawm cov phom sij tshwj xeeb hauv koj ib puag ncig.
2. Ingress tiv thaiv (IP) qib
Tus IP kev ntaus nqi qhia tau tias qhov ntim tau muaj peev xwm tiv taus plua plav thiab dej intrusion. Rau thaj chaw muaj kev phom sij, qhov kev ntsuam xyuas tus IP siab dua IP feem ntau yog xav tau. Saib rau qhov chaw ntim nrog tus IP kev ntsuam xyuas tsawg kawg iP65 txhawm rau tiv thaiv plua plav thiab cov dej kub uas tsis muaj siab.
3. Kev tawg-cov qauv pov thawj
Muaj kev tiv thaiv tawg ntau yam muaj, suav nrog:
- Tawg tawg (ex D): Tsim kom tiv thaiv cov zaub mov tawg hauv qhov thaiv thiab tiv thaiv nplaim taws los ntawm kev khiav dim.
- Txhim kho kev nyab xeeb (ex e): Kom ntseeg tau cov cuab yeej tsim los txo qis kev pheej hmoo ntawm hluav taws.
- Intrinsic kev nyab xeeb (ex i): Txwv lub zog muaj rau ignition, ua kom haum rau thaj chaw 0 thiab thaj tsam 1 daim ntawv thov.
Nkag siab txog cov hau kev no yuav pab koj xaiv cov kab ke uas ua tau raws li cov kev xav tau ntawm thaj chaw muaj kev phom sij.
4. Qhov loj me thiab kev teeb tsa
Lub ntim yuav tsum tau me me kom haum rau cov khoom siv thaum tso cai rau qhov cua thiab cua sov dissipation. Xav txog qhov kev teeb tsa ntawm koj kev teeb tsa thiab ua kom pom tseeb tias qhov ntim tau yooj yim rau kev saib xyuas thiab tshuaj xyuas.
5. Ntawv Pov Thawj thiab Ua Raws
Nco ntsoov tias cov phiaj xwm ua tau raws li cov qauv thiab ntawv pov thawj, xws li ATEX (rau Tebchaws Europe) lossis NEC (rau Tebchaws Meskas). Cov ntawv pov thawj no qhia tau tias lub rooj zaum tau raug sim thiab ua tau raws li kev nyab xeeb kev nyab xeeb cov chaw muaj kev phom sij.
6. Ib puag ncig ib puag ncig
Xav txog cov xwm txheej ib puag ncig uas lub txee yuav ntsia tau. Yam khoom xws li huab cua sov heev, av noo, thiab kis tau cov tshuaj chilations tuaj yeem cuam tshuam qhov kev xaiv ntawm cov ntaub ntawv uas siv thiab tsim qauv.
Hauv kev xaus
Xaiv qhov tseebThaj tsam muaj kev phom sijyog qhov kev txiav txim siab tseem ceeb cuam tshuam rau kev nyab xeeb thiab ua raws li cov chaw muaj ib puag ncig. Los ntawm kev xav txog yam xws li cov khoom xaiv, IP kev xaiv, loj, cov teeb meem thiab kev xaiv ib puag ncig kom cov neeg thiab khoom siv kom nyab xeeb. Nco ntsoov nrog tus kws tshaj lij thiab ua raws cov cai hauv zos kom ntseeg tau tias koj cov chaw ua kom muaj kev phom sij ua tau raws li txhua tus qauv kev nyab xeeb.
