90% ntawm kev sib tsoo tawg yog tshwm sim los ntawm kev xaiv cov khoom siv tsis raug!

Kev tawg ntawm kev lag luam yog kev puas tsuaj loj-tab sis feem ntau yog tiv thaiv tsis tau. Yog tias koj ua haujlwm hauv roj & roj, kev ua tshuaj lom neeg, lossis kev lag luam muaj kev phom sij, phau ntawv qhia no yog rau koj. Kawm yuav ua li cas xaiv cov khoom tawg-pov thawj txoj cai uas ua tau raws li cov qauv thoob ntiaj teb thiab tiv thaivob kojneeg thiab khoom muaj nqis.

1. Kev nkag siab tusExplosion-Proof Markings

Txhuatau ntawv pov thawjntaus ntawv nqa cov cim tseem ceeb, xws li:
Roj:Ex db ⅡC T6 Gb / Plua plav:Ex tb ⅢC T85 ℃ Db

Cov cai notxhais tau tiass:

Ex db= Flameproof tiv thaiv (rau roj ib puag ncig)

ⅡC= Siab tshajkev pheej hmoo gas pab pawg(Hydrogen, acetylene)

T6= Qhov kub siab tshaj plaws saum npoo ≤ 85 ° C (kev ntsuam xyuas nyab xeeb)

ⅢC= Siab tshajphom plua plav pawg(conductive hlau zoo li aluminium / magnesium)

Pebtawg-pov thawj damper actuatorsUa raws li cov qauv no, ua kom muaj kev nyab xeeb siab tshaj plaws.

2. Hom Kev Tiv Thaiv Pov Hwm Pov Hwm (Koj Puas Xav Tau?)

※ Peb cov khoom siv Flameproof (Ex db), zoo tagnrho rau high-power industrial applications hauv Zone 1/2.

3. Paub Koj Ib puag ncig: Gas & Dust Hazards

Gas Explosive Environments (Class II)

ⅡA(Kev pheej hmoo tsawg) - Propane, butane

ⅡB(Kev pheej hmoo nruab nrab) - Ethylene, kev lag luam roj

ⅡC(Qhov kev pheej hmoo siab tshaj) - Hydrogen, acetylene

Plua plav Environments (Class III)

ⅢA- Flammable fibers (paj rwb, ntoo)

ⅢB- Cov hmoov av uas tsis yog-conductive (cov hmoov nplej, thee)

ⅢC- Cov hmoov av conductive ( txhuas, magnesium)

※ Peb cov cuab yeej siv npog ⅡB, ⅡC (gas) thiab ⅢC (plua plav)—cov xwm txheej muaj kev phom sij tshaj plaws.

4. Qhov ntsuas kub ntsuas qhov ntsuas-T6 yog qhov nyab xeeb tshaj plaws

※ Pebtawg-pov thawj dampersyog T6-rated-qhov siab tshaj plawskev nyab xeeb ntsuas rau qhov kub thiab txias.

5. Cov cheeb tsam txaus ntshai Zoning:Xaiv cov cuab yeej zoo rau qhov chaw

RojThaj chaw

Zone 0– Tsis tu ncuamuaj roj(piv txwv li, hauv cov roj tank)

Zone 1-Nquag muaj roj(eg, tshuaj reactor, uathaj chaw)

Zone 2-Qee zauspheej hmoo (piv txwv li, sab nraum zoov loadingcheeb tsams, chaw kho mob)

Plua plavZones

Zone 20- Cov huab cua tsis tu ncua (piv txwv li, hauv silos)

Zone 21-Tsis tshua muaj plua plav(piv txwv li, conveyor siv)

Zone 22- Tsis tshua muaj plua plav tawm (piv txwv li, lim dej)

※ Peb cov khoom muaj ntawv pov thawj rau Zone 1/2 (gas) thiab Zone 21/22 (dust).

Xaus: Xaiv Txoj Cai, Nyob Zoo

Kev tiv thaiv tawg tsis yog hais txog kev ua raws cai nkaus xwb - nws yog hais txog lub luag haujlwm. Nrog:

●Flameproof Ex dbtsim,

●Daim ntawv pov thawj rauIIC/IIIC ib puag ncig,

●T6-rated thermal kev nyab xeeb, thiab

●Ua raws liATEX & IECEx

Peb cov khoom pov thawj tawg tau tso siab rau hauv cov xwm txheej hnyav tshaj plaws thoob ntiaj teb.

Tsis txhob cuam tshuam. Hloov kho kom tau ntawv pov thawj kev nyab xeeb hnub no.
