1, Core Framework of ATEX Certification: Explosion proof System los ntawm Cov Lus Qhia rau Standard
ATEX daim ntawv pov thawj yog los ntawm EU Cov Lus Qhia rau Cov Khoom Siv thiab Cov Txheej Txheem Tiv Thaiv rau Cov Txheej Txheem Tshaj Lij Ib puag ncig (2014/34/EU), uas hloov 1994 Cov Lus Qhia 94/9/EC thiab tsim kom muaj kev tawg- cov ntaub ntawv pov thawj kev cai npog ob qho tib si kuv thiab cov khoom tsis yog mine. Cov ntsiab lus tseem ceeb yog los sib sau ua ke cov kev xav tau kev nyab xeeb ntawm kev tawg- cov khoom pov thawj hauv European lag luam los ntawm ob lub tswv yim ntawm "kev cai lij choj + cov qauv sib koom tes":
Nyob rau theem ntawm cov kev cai lij choj: Cov lus qhia qhia meej tias cov cuab yeej yuav tsum tau ua raws li Cov Cai Tswj Xyuas Kev Noj Qab Haus Huv thiab Kev Nyab Xeeb (EHSR), suav nrog kev tiv thaiv cov khoom siv hluav taws xob, txwv tsis pub sib kis ntawm lub zog tawg, thiab yuam kom cov cuab yeej yuav tsum tau ua tus cim CE ua ntej nkag mus rau EU kev ua lag luam.
Nyob rau theem ntawm cov qauv kev sib koom ua ke: Lub Koom Haum European rau Standardization (CEN / CENELEC) tsim cov qauv xws li EN 60079 series (cov khoom siv hluav taws xob) thiab EN 13463 series (tsis yog cov khoom siv hluav taws xob), ua kom zoo dua cov ntsiab lus xws li tawg- qauv tsim thiab kev sim. Piv txwv li, EN 60079-0 qhia tias cov cuab yeej yuav tsum raug kuaj xyuas kom muaj kev ua haujlwm tawg los ntawm kev ntsuas hluav taws xob, ntsuas kub, thiab lwm yam.
ATEX certification categorizes cov cuab yeej ua ob hom loj:
Pawg I: Cov cuab yeej siv mining, ntxiv muab faib ua M1 (siab tiv thaiv qib) thiab M2 (siab tiv thaiv qib);
Pawg II: Cov khoom siv tsis yog mining, muab faib rau hauv Qeb 1 (theem tiv thaiv siab heev), Qeb 2 (siab tiv thaiv qib), thiab Qib 3 (qib tiv thaiv ib txwm) raws li qhov zaus thiab lub sijhawm ntawm qhov chaw tawg.
2, Cov ntaub ntawv pov thawj tawg rau M12 cable adapters: kev hloov kho kom zoo ntawm cov qauv mus rau cov khoom siv
Hauv qhov chaw tawg, qhov tawg- pov thawj tsim ntawm M12 adapters yuav tsum tau daws ob qhov teeb meem tseem ceeb:
Tiv thaiv kom tsis txhob muaj hluav taws xob sab hauv qhov hluav taws xob: Cov hlau sib txuas hauv lub adapter tuaj yeem tsim hluav taws xob hluav taws xob thaum ntsaws lossis siv hluav taws xob, thiab qhov hluav taws xob hluav taws xob yuav tsum raug cais tawm los ntawm kev tawg- cov ntaub ntawv pov thawj, kev tsim kev nyab xeeb ntxiv, lossis kev nyab xeeb hauv vaj huam sib luag (xws li kev txwv tam sim no / voltage).
Kev txwv qhov kub thiab txias ntawm lub casing: Lub tshav kub tsim thaum lub sij hawm ua hauj lwm cov cuab yeej yuav ignite ib puag ncig combustibles, thiab xaiv cov khoom (xws li stainless hlau casing) thiab cua sov dissipation tsim yuav tsum tau siv los xyuas kom meej tias qhov kub ntawm qhov kub ntawm combustibles (xws li T4 pab pawg neeg yuav tsum tau tsawg tshaj li los yog sib npaug rau 135 degree).
Noj M12 tawg- cov ntaub ntawv pov thawj adapter ntawm qee lub npe ua piv txwv, nws tus qauv tsim yuav tsum ua kom tau raws li cov cai hauv qab no ATEX:
Kev tiv thaiv tus qauv: Txais IP67 qib tiv thaiv kom tsis txhob muaj plua plav nkag mus rau sab hauv; Plhaub thickness Ntau dua los yog sib npaug li 2 hli, muaj peev xwm tiv taus qhov tawg siab tsis muaj qhov tawg;
Kev xaiv cov khoom siv: Cov khoom sib tiv tauj yog ua los ntawm kub-plated tooj liab alloy kom txo tau kev sib cuag thiab kub tsim; Lub plhaub yog ua los ntawm 316L stainless hlau, uas yog corrosion-resistant thiab muaj thermal conductivity zoo heev;
Kev tswj qhov kub thiab txias: Ua kom zoo dua cov cua kub dissipation qauv los ntawm thermal simulation los xyuas kom meej tias qhov kub ntawm qhov saum npoo yog tsawg dua los yog sib npaug rau 120℃hauv qab 16A tam sim no (raws li T4 pawg);
Daim ntawv pov thawj: Lub plhaub yog engraved nrog "Ex d IIC T4 Gb" cim, qhia tias nws yog haum rau Class IIC gas ib puag ncig (xws li hydrogen), T4 kub pab pawg neeg, thiab yog ib tug flameproof hom (d) khoom.
3, ATEX daim ntawv pov thawj txheej txheem: nruj tswj los ntawm kev tsim mus rau ntau lawm
M12 adapter yuav tsum mus dhau cov kauj ruam tseem ceeb hauv qab no kom tau txais ntawv pov thawj ATEX:
Kev soj ntsuam kev pheej hmoo: Txiav txim siab qib kev tiv thaiv raws li cov cuab yeej siv scenario (xws li Zone 0, Zone 1 lossis Zone 20, Zone 21), thiab xaiv qhov kev tawg uas siv tau- hom pov thawj (xws li nplaim hluav taws, muaj kev nyab xeeb ntxiv, kev nyab xeeb sab hauv).
Tsim kev pov thawj: Ua hom kev xeem raws li EN 60079 series qauv, suav nrog:
Kev ntsuas hluav taws xob: Simulate qhov phem tshaj - cov xwm txheej (xws li luv luv Circuit Court, overload) los xyuas seb lub txim hluav taws xob puas tuaj yeem cuam tshuam cov qauv sib xyaw roj;
Kev ntsuas kub: Ua haujlwm tsis tu ncua ntawm qhov ntsuas tam sim no thiab ntsuas seb qhov kub ntawm lub plhaub puas qis dua qhov ntsuas kub;
Kev ntsuam xyuas lub zog siv tshuab: Siv cov kev cuam tshuam thiab kev co rau qhov tawg - pov thawj lub plhaub los xyuas nws qhov tseeb.
Kev tswj hwm ntau lawm: Tsim kom muaj kev tswj xyuas zoo (xws li ISO 9001) kom ntseeg tau tias txhua pawg ntawm cov khoom lag luam zoo ib yam nrog cov qauv xa tawm. Piv txwv li, ib lub Hoobkas tswj cov tuab ntawm cov txheej kub plating (± 0.5 μ m) los ntawm kev siv cov kab ntau lawm kom tsis txhob muaj kev tiv thaiv ntau dhau.
Kev tshaj tawm lub cev tshuaj xyuas: EU tso cai cov koom haum (xws li T Ü V, SGS) tshuaj xyuas cov ntaub ntawv kev tshaj lij, cov ntawv tshaj tawm, thiab cov txheej txheem tsim khoom, thiab muab ATEX daim ntawv pov thawj tom qab dhau qhov kev tshuaj xyuas.
4, Tus nqi ntawm ATEX Certification nyob rau hauv M12 Adapter Market: Dual Enhancement of Safety thiab Competitiveness
Kev nkag mus rau kev ua lag luam: EU kev lag luam yuav kwv yees li 3 billion euros ntawm kev tawg- cov khoom pov thawj txhua xyoo, thiab ATEX ntawv pov thawj yog qhov yuav tsum tau nkag mus rau hauv lub khw no. Piv txwv li, Suav chaw tsim khoom lag luam M12 adapter tsis dhau ATEX daim ntawv pov thawj, ua rau nws tsis muaj peev xwm koom nrog European petrochemical qhov kev sib tw.
Kev lees paub txog kev nyab xeeb: Nyob rau hauv kev sib tsoo tawg ntawm cov nroj tsuag tshuaj hauv lub tebchaws Yelemes, qhov tsis muaj ntawv pov thawj M12 adapter ua rau hluav taws xob cuam tshuam vim kev sib cuag tsis zoo, igniting leaked ethylene gas thiab ua rau poob loj; Cov kab ntau lawm siv ATEX certified adapters tsis tau cuam tshuam, qhia txog kev nyab xeeb ntawm cov ntawv pov thawj rau cov neeg ua haujlwm thiab cov khoom siv.
Kev hloov kho thev naus laus zis: ATEX daim ntawv pov thawj tsav kev txhim kho ntawm M12 adapters rau kev ua haujlwm siab. Piv txwv li, ib lub hom phiaj tau tshaj tawm X-code tawg- pov thawj adapter uas txhawb nqa 10Gbps kis tau tus mob. Tom qab dhau ATEX daim ntawv pov thawj, nws tau ua tiav rau siab - cov ntaub ntawv tau txais ceev hauv European cua ua liaj ua teb.
