Hauv ntau yam xws li roj, tshuaj nroj tsuag, mining, hluav taws kub ceev kev nyab xeeb, tshuaj, thiab ua zaub mov, ib puag ncig muaj kev cuam tshuam rau kev tawg yog tshwm sim thaum tsim khoom, ua, khaws cia, thiab logistics. Txhawm rau ua kom tus kheej thiab tsim kev nyab xeeb, cov khoom siv hluav taws xob siv nyob rau hauv cov cheeb tsam no yuav tsum muaj ntawv pov thawj tawg.
Txhais
Dab tsi yog daim ntawv pov thawj rau cov khoom tawg-pov thawj hluav taws xob? Nws hais txog kev lees paub ntawm cov khoom siv hluav taws xob siv hauv kev lag luam xws li roj, tshuaj nroj tsuag, thee mining, light textiles, thiab kev ua qoob loo, qhov twg tawg cov pa, hmoov av, los yog fibers yuav tsub kom.
Txhua cheeb tsam thoob ntiaj teb muaj cov qauv sib txawv thiab cov tshuab rau kev lees paub cov khoom siv hluav taws xob tawg. Cia peb tshawb xyuas qee qhov kev lees paub thoob ntiaj teb no.
IECEx
IECEx system, tawm suab los ntawm International Electrotechnical Commission (IEC), aims kom tshem tawm qhov sib txawv ntawm cov tshuab thiab cov kev pab cuam uas siv nyob rau hauv explosive puag ncig lub ntiaj teb no, txhawb kev lag luam thoob ntiaj teb thaum ua kom muaj kev nyab xeeb. Tus qauv tam sim no yog IEC 60079.
Daim ntawv pov thawj IECEx tau dhau los ua txoj hauv kev zoo tshaj plaws rau kev lees paub kev nyab xeeb thoob ntiaj teb rau cov khoom lag luam hauv thaj chaw muaj kev phom sij thiab tau lees paub hauv ntau lub tebchaws, suav nrog Australia, New Zealand, Brazil, Canada, Tuam Tshoj, Nyiv, Kaus lim qab teb, Malaysia, Singapore, South Africa, thiab lub tebchaws United States.
Cov ntawv pov thawj uas tau muab los ntawm IECEx tau tso rau hauv lawv lub vev xaib, qhov twg manufacturers thiab cov neeg siv kawg tuaj yeem nrhiav cov ntaub ntawv cuam tshuam.
ATEX
ATEX system, tau txais los ntawm European Commission, aims los tsim kom muaj kev sib koom ua lag luam nyob hauv Europe, tshem tawm kev teeb meem kev lag luam thiab ua kom muaj kev ywj pheej ntawm cov tshuab rau qhov muaj peev xwm tawg tau ntawm cov tswv cuab hauv lub xeev. Cov lus qhia no suav nrog cov khoom siv mining thiab cov khoom tsis yog mining, txuas ntxiv cov ntsiab lus ntawm qhov chaw muaj peev xwm tawg tau kom muaj plua plav, nplaim taws cov pa, vapors, thiab huab cua hauv huab cua, thiab teev cov txheej txheem kev noj qab haus huv thiab kev nyab xeeb thiab cov txheej txheem ntsuas kev ua raws li cov txheej txheem rau cov tshuab uas npaj rau ib puag ncig zoo li no. Cov lus qhia tam sim no yog ATEX 100A.
CNEX
Tuam Tshoj CNEX daim ntawv pov thawj system, saib xyuas los ntawm National Supervision and Inspection Center for Explosion Protection and Safety of Instrumentation (CQST), yog raws li lub teb chaws tus qauv zoo li lub GB3836 series. Nws suav nrog kev tshuaj xyuas thiab tshuaj xyuas kev ua haujlwm tawg-pov thawj rau ntau yam khoom, suav nrog cov motors, khoom siv hluav taws xob, teeb pom kev zoo, cuab yeej, cov khoom siv sib txuas lus, tsheb, thiab cov cuab yeej siv tshuab xws li elevators thiab cranes, muab pov thawj tawg pov thawj raws li.
North America
Hauv North America, txoj kev nyab xeeb tshaj plaws yog raws li National Electrical Code (NEC), nrog UL913 thiab TIA4950 ua tus thawj explosion-proof standard.
Canada
Canada lub system, saib xyuas los ntawm Canadian Standards Association (CSA), lub teb chaws cov ntaub ntawv pov thawj kev nyab xeeb loj tshaj plaws thiab lub tuam txhab ua qauv tsim thiab cov ntawv pov thawj zoo, tam sim no adopts cov CSA 60079 txheem rau explosion-proof ntawv pov thawj.
