Phau ntawv qhia txog kev xaiv qhov chaw muaj kev phom sij zoo

Kev xaiv qhov chaw kaw yog qhov tseem ceeb heev thaum nws los txog rau kev ua kom muaj kev nyab xeeb ntawm cov chaw ua haujlwm, tshwj xeeb tshaj yog cov chaw txaus ntshai. Cov chaw kaw hauv thaj chaw txaus ntshai yog tsim los tiv thaiv cov khoom siv hluav taws xob ntawm cov pa roj tawg, hmoov av thiab lwm yam teeb meem ib puag ncig. Phau ntawv qhia no yuav pab koj taug kev ntawm qhov nyuaj ntawm kev xaiv ib qhothaj chaw muaj kev phom sijqhov ntawd yog rau koj cov kev xav tau tshwj xeeb.

To taub qhov chaw txaus ntshai

Ua ntej yuav pib xaiv cov chaw, yuav tsum nkag siab tias thaj chaw twg yog thaj chaw txaus ntshai. Cov chaw no raug faib ua pawg raws li qhov muaj cov pa roj, cov pa dej lossis cov hmoov av uas yooj yim hlawv. Feem ntau cov txheej txheem faib ua pawg muaj xws li:

• Cheeb Tsam 0Ib qho chaw uas muaj cov pa roj tawg tas mus li lossis ntev heev.
• Cheeb Tsam 1Ib cheeb tsam uas muaj huab cua roj tawg thaum lub sijhawm ua haujlwm ib txwm.
• Cheeb Tsam 2: Tej pa roj tawg yuav tsis tshwm sim thaum lub sijhawm ua haujlwm ib txwm, thiab yog tias nws tshwm sim, nws tsuas yog muaj nyob rau lub sijhawm luv luv xwb.

Txhua thaj chaw xav tau ib hom kev kaw tshwj xeeb kom ntseeg tau tias muaj kev nyab xeeb thiab ua raws li cov cai.

Cov Kev Xav Tseem Ceeb hauv Kev Xaiv Cov Chaw Muaj Kev Phom Sij

1. Kev Xaiv Khoom Siv

Cov khoom siv ntawm lub thawv yog qhov tseem ceeb rau kev ruaj khov thiab kev nyab xeeb. Cov khoom siv feem ntau suav nrog:

• Cov hlau tsis xeb: Muaj kev tiv thaiv corrosion zoo heev, zoo tagnrho rau cov chaw ib puag ncig hnyav.
• Aluminium: Sib dua thiab tiv taus xeb, tab sis tej zaum yuav tsis haum rau txhua qhov chaw txaus ntshai.
• Polycarbonate: Muab kev tiv thaiv zoo rau kev cuam tshuam thiab feem ntau yog siv rau hauv qhov chaw tsis hnyav.

Kev xaiv cov khoom siv zoo yuav nyob ntawm seb muaj kev phom sij tshwj xeeb li cas hauv koj ib puag ncig.

2. Kev Tiv Thaiv Kev Nkag (IP) Qib

Qhov ntsuas IP qhia txog lub peev xwm ntawm lub thawv tiv taus plua plav thiab dej nkag. Rau thaj chaw muaj kev phom sij, feem ntau yuav tsum muaj qhov ntsuas IP siab dua. Nrhiav lub thawv uas muaj qhov ntsuas IP tsawg kawg yog IP65 kom ntseeg tau tias tiv taus plua plav thiab dej ntws qis.

3. Cov txheej txheem tiv thaiv kev tawg

Muaj ntau txoj kev tiv thaiv kev tawg sib txawv, suav nrog:

• Tiv thaiv kev tawg (Ex d)Tsim los kom tiv taus kev tawg hauv qhov chaw kaw thiab tiv thaiv cov nplaim taws kom tsis txhob khiav tawm.
• Kev Nyab Xeeb Zoo Dua (Ex e)Xyuas kom tseeb tias cov khoom siv tau tsim los kom txo qhov kev pheej hmoo ntawm hluav taws.
• Kev Nyab Xeeb Sab Hauv (Ex i)Txwv lub zog muaj rau kev hlawv, ua rau nws tsim nyog rau thaj tsam 0 thiab thaj tsam 1 daim ntawv thov.

Kev nkag siab txog cov hau kev no yuav pab koj xaiv ib qho chaw kaw uas ua tau raws li cov kev cai tshwj xeeb ntawm cov chaw muaj kev phom sij.

4. Qhov Loj thiab Kev Teeb Tsa

Lub thawv yuav tsum loj txaus kom haum rau cov khoom siv thaum tseem tso cai rau cua nkag thiab cua sov kom zoo. Xav txog qhov layout ntawm koj qhov kev teeb tsa thiab xyuas kom meej tias lub thawv yooj yim nkag mus rau kev saib xyuas thiab kev tshuaj xyuas.

5. Daim Ntawv Pov Thawj thiab Kev Ua Raws Cai

Xyuas kom tseeb tias lub thawv kaw ua tau raws li cov qauv thiab daim ntawv pov thawj, xws li ATEX (rau Tebchaws Europe) lossis NEC (rau Tebchaws Meskas). Cov ntawv pov thawj no qhia tias lub thawv kaw tau raug sim thiab ua tau raws li cov cai kev nyab xeeb rau thaj chaw muaj kev phom sij.

6. Tej yam kev mob ib puag ncig

Xav txog tej yam ib puag ncig uas yuav muab lub txee tso rau hauv. Tej yam xws li qhov kub thiab txias heev, av noo, thiab kev raug tshuaj lom neeg tuaj yeem cuam tshuam rau kev xaiv cov ntaub ntawv thiab kev tsim qauv ntawm lub txee.

xaus lus

Xaiv qhov yogthaj chaw muaj kev phom sijyog qhov kev txiav txim siab tseem ceeb uas cuam tshuam rau kev nyab xeeb thiab kev ua raws li txoj cai hauv cov chaw ua haujlwm. Los ntawm kev xav txog cov yam xws li kev xaiv cov khoom siv, qib IP, txoj kev tiv thaiv kev tawg, qhov loj me, daim ntawv pov thawj thiab cov xwm txheej ib puag ncig, koj tuaj yeem ua qhov kev xaiv paub kom cov neeg thiab cov khoom siv muaj kev nyab xeeb. Nco ntsoov sab laj nrog tus kws tshaj lij thiab ua raws li cov cai hauv zos kom ntseeg tau tias koj qhov chaw muaj kev phom sij ua tau raws li txhua tus qauv kev nyab xeeb tsim nyog.
