Kev xaiv enclosure yog ib qho tseem ceeb thaum nws los ua kom muaj kev nyab xeeb ntawm kev lag luam ib puag ncig, tshwj xeeb tshaj yog cov chaw muaj kev phom sij. Cov chaw muaj kev puas tsuaj yog tsim los tiv thaiv cov khoom siv hluav taws xob los ntawm cov pa tawg, plua plav thiab lwm yam ib puag ncig. Phau ntawv qhia no yuav pab koj nrhiav qhov nyuaj ntawm kev xaiv ibthaj chaw muaj kev phom sijuas yog rau koj cov kev xav tau tshwj xeeb.
Nkag siab thaj tsam txaus ntshai
Ua ntej dhia mus rau hauv txoj kev xaiv, nws yog ib qho tsim nyog yuav tsum nkag siab tias qhov twg yog qhov chaw muaj kev phom sij. Cov cheeb tsam no raug cais raws li qhov muaj cov pa taws, vapors lossis hmoov av. Classification systems feem ntau muaj xws li:
- Zone 0: Ib qho chaw uas muaj cov pa roj tawg tsis tu ncua los yog ntev.
- Zone 1: Ib cheeb tsam uas muaj cua daj cua dub tshwm sim thaum lub sijhawm ua haujlwm ib txwm muaj.
- Zone 2: Cov pa cua tawg tsis zoo li tshwm sim thaum lub sijhawm ua haujlwm ib txwm muaj, thiab yog tias nws ua, nws tsuas yog muaj nyob rau lub sijhawm luv luv xwb.
Txhua cheeb tsam yuav tsum muaj ib hom kev thaiv tshwj xeeb kom muaj kev nyab xeeb thiab ua raws li cov cai.
Cov kev txiav txim siab tseem ceeb hauv Kev Xaiv Cov Chaw Tiv Thaiv Kev Nyab Xeeb
1. Kev xaiv khoom
Cov khoom ntawm rooj plaub yog qhov tseem ceeb rau kev ua haujlwm ntev thiab kev nyab xeeb. Cov ntaub ntawv uas muaj xws li:
- Stainless hlau: Muaj kev tiv thaiv corrosion zoo heev, zoo tagnrho rau qhov chaw hnyav.
- Aluminium: Lub teeb yuag thiab corrosion-resistant, tab sis tej zaum yuav tsis haum rau txhua qhov chaw txaus ntshai.
- Polycarbonate: Muab kev cuam tshuam zoo thiab feem ntau yog siv nyob rau hauv qhov chaw hnyav dua.
Xaiv cov khoom tsim nyog yuav nyob ntawm seb muaj xwm txheej tshwj xeeb uas muaj nyob hauv koj ib puag ncig.
2. Ingress Protection (IP) Qib
Qhov ntsuas IP qhia tau hais tias lub kaw lus muaj peev xwm tiv thaiv plua plav thiab dej nkag. Rau thaj chaw muaj kev phom sij, feem ntau yuav tsum muaj qhov ntsuas IP siab dua. Nrhiav ib lub qhov rooj nrog tus IP ntsuam xyuas tsawg kawg yog IP65 kom muaj kev tiv thaiv cov plua plav thiab cov dav hlau tsis tshua muaj dej.
3. Cov txheej txheem tawg-pov thawj
Muaj ntau txoj hauv kev tiv thaiv tawg, suav nrog:
- Explosionproof (Ex d): Tsim los tiv thaiv kev tawg hauv lub qhov rooj thiab tiv thaiv cov nplaim taws los ntawm kev khiav tawm.
- Txhim kho kev nyab xeeb (Ex e): Xyuas kom cov cuab yeej tsim los txo qhov kev pheej hmoo ntawm hluav taws.
- Intrinsic Safety (Ex kuv): Txwv tsis pub muaj hluav taws xob hluav taws xob, ua rau nws haum rau Zone 0 thiab Zone 1 daim ntawv thov.
Kev nkag siab txog cov txheej txheem no yuav pab koj xaiv ib lub thawv uas ua tau raws li cov cai tshwj xeeb ntawm cov chaw muaj kev phom sij.
4. Loj thiab Configuration
Lub enclosure yuav tsum tau qhov loj me kom haum rau cov khoom siv thaum tso cai rau qhov cua kom zoo thiab cua sov dissipation. Xav txog qhov kev teeb tsa ntawm koj qhov kev teeb tsa thiab xyuas kom tseeb tias lub qhov rooj nkag tau yooj yim rau kev saib xyuas thiab tshuaj xyuas.
5. Ntawv pov thawj thiab ua raws
Nco ntsoov tias lub kaw lus ua tau raws li cov qauv thiab cov ntawv pov thawj, xws li ATEX (rau Europe) lossis NEC (rau Tebchaws Meskas). Cov ntawv pov thawj no qhia tau hais tias lub kaw lus tau raug sim thiab ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb rau thaj chaw muaj kev phom sij.
6. Ib puag ncig tej yam kev mob
Xav txog tej yam kev mob nyob rau hauv uas lub txee yuav raug ntsia. Cov yam ntxwv xws li qhov kub thiab txias, av noo, thiab raug tshuaj lom neeg tuaj yeem cuam tshuam rau kev xaiv ntawm cov ntaub ntawv kaw thiab tsim.
nyob rau hauv xaus
Xaiv qhov raugthaj chaw muaj kev phom sijyog qhov kev txiav txim siab tseem ceeb uas cuam tshuam txog kev nyab xeeb thiab kev ua raws cai hauv thaj chaw muaj kev lag luam. Los ntawm kev txiav txim siab txog yam xws li kev xaiv cov khoom siv, kev ntsuam xyuas IP, txoj kev tiv thaiv tawg, qhov loj me, ntawv pov thawj thiab ib puag ncig, koj tuaj yeem ua qhov kev xaiv kom paub meej kom tib neeg thiab khoom siv nyab xeeb. Nco ntsoov sab laj nrog tus kws tshaj lij thiab ua raws li cov cai hauv cheeb tsam kom ntseeg tau tias koj qhov chaw muaj phom sij ua tau raws li cov qauv kev nyab xeeb tsim nyog.
