Cov neeg tsim khoom tsim tau feem ntau muaj cov ntaub ntawv pov thawj ntawm kev tsim cov khoom pov thawj uas ua tau raws li cov qauv kev lag luam. Lawv kuj muab kev pab cuam tom qab muag zoo, nrog rau kev saib xyuas thiab kev txhawb nqa rov qab. Ua haujlwm nrog cov tuam txhab ntseeg siab txo qis kev pheej hmoo thiab ua kom cov cuab yeej ua tau raws li qhov xav tau hauv qhov chaw muaj kev phom sij.

Cov lus nug nug manufacturers txog cov ntawv pov thawj

Cov neeg yuav khoom yuav tsum nug cov tuam txhab cov lus nug tshwj xeeb txog cov ntawv pov thawj kom ntseeg tau tias ua raws. Cov lus nug tseem ceeb muaj xws li:

• Cov ntawv pov thawj twg cov khoom tuav (xws li UL, ATEX, IECEx)?
• Cov chaw tsim khoom puas tuaj yeem muab cov ntaub ntawv pov thawj cov ntawv pov thawj no?
• Cov khoom puas raug kuaj rau thaj tsam tshwj xeeb, xws li Zone 1 lossis Zone 2?
• Yuav tsum muaj cov txheej txheem tu lossis rov ua dua tshiab li cas?

Cov lus nug no pab cov neeg yuav khoom txiav txim siab paub thiab xaiv cov khoom uas ua tau raws li lawv cov kev xav tau ua haujlwm.

Cov ntaub ntawv pov thawj ua haujlwm tawg tawg, xws li UL, ATEX, thiab IECEx, ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua raws li qhov chaw muaj kev phom sij. Cov ntawv pov thawj no tsis tsuas yog tiv thaiv cov neeg ua haujlwm tab sis kuj txhim kho kev ua haujlwm zoo. Piv txwv li, daim ntawv pov thawj IECEx ua raws li cov qauv kev nyab xeeb thoob ntiaj teb, txo cov nqi thiab sijhawm rau cov tuam txhab thaum tswj kev nyab xeeb. Ib yam li ntawd, kev ua raws li NEC thiab ATEX cov qauv yog qhov tseem ceeb rau kev lag luam xws li roj thiab roj, qhov chaw tawg-pov thawj teeb pom kev zoo txo ​​qis kev pheej hmoo thiab txhim kho kev ntseeg tau.

Kev nqis peev hauv cov teeb pom kev zoo uas tau lees paub muaj txiaj ntsig ntev. LED tawg-pov thawj tshuab, piv txwv li, tuaj yeem txo kev siv hluav taws xob ntau txog 90% thiab kav ntev txog 100,000 teev, txo qis kev xav tau kev saib xyuas. Cov neeg yuav khoom yuav tsum tau txheeb xyuas cov ntawv pov thawj thiab xaiv cov khoom lag luam los ntawm cov tuam txhab ntseeg siab kom ntseeg tau tias muaj kev nyab xeeb, ua raws, thiab kav ntev.

FAQ

1. Qhov "explosion-proof" txhais li cas rau lub teeb ua haujlwm?

Lub teeb ua haujlwm tawg yog tsim los tiv thaiv cov hluav taws xob sab hauv lossis cua sov los ntawm cov hluav taws kub nyhiab, vapors, lossis plua plav hauv qhov chaw muaj kev phom sij. Cov teeb no ua tau raws li cov qauv kev nyab xeeb nruj kom ntseeg tau tias muaj kev nyab xeeb ua haujlwm hauv cov huab cua uas tuaj yeem tawg.

2. Cov neeg yuav khoom tuaj yeem txheeb xyuas cov khoom pov thawj li cas?

Cov neeg yuav khoom tuaj yeem txheeb xyuas cov ntawv pov thawj los ntawm kev txheeb xyuas cov ntaub ntawv pov thawj los ntawm cov ntawv pov thawj xws li UL, ATEX, lossis IECEx. Cov ntawv teev npe no lees paub cov khoom ua raws li qhov tseeb thiab qhov tseeb, ua kom nws ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb rau qhov chaw muaj kev phom sij.

3. Puas yog daim ntawv pov thawj zoo li UL thiab ATEX hloov pauv tau?

Tsis yog, cov ntawv pov thawj zoo li UL thiab ATEX yog cov cheeb tsam tshwj xeeb. UL siv rau North America, thaum ATEX yog qhov yuav tsum tau ua hauv European Union. Cov lag luam ua haujlwm thoob ntiaj teb yuav tsum xav txog daim ntawv pov thawj IECEx rau kev ua raws li dav.

4. Vim li cas daim ntawv lo tsim nyog tseem ceeb rau lub teeb tawg?

Kev sau npe kom raug muab cov ntaub ntawv tseem ceeb, xws li kev faib chaw txaus ntshai thiab cov qauv ua raws. Nws ua kom cov neeg siv tuaj yeem txheeb xyuas cov khoom tsim nyog rau ib puag ncig tshwj xeeb thiab zam kev ua txhaum cai.

5. Muaj pes tsawg lub teeb hluav taws xob yuav tsum rov ua dua tshiab?

Daim ntawv pov thawj rov qab sib txawv ntawm lub cev ntawv pov thawj thiab hom khoom. Kev tshuaj xyuas thiab kev saib xyuas tsis tu ncua ua kom muaj kev ua raws li cov qauv kev nyab xeeb, tiv thaiv cov neeg ua haujlwm thiab cov khoom siv thaum lub sijhawm.
