90% ntawm qhov xwm txheej tawg yog tshwm sim los ntawm kev xaiv cov khoom siv tsis raug!
Txhuatau ntawv pov thawjlub cuab yeej muaj cov cim tseem ceeb, xws li:
Roj: Ex db ⅡC T6 Gb / Pluav: Ex tb ⅢC T85 ℃ Db
Cov lej nonruab nrabs:
Ex db= Kev tiv thaiv hluav taws (rau cov chaw muaj roj)
ⅡC= Siab tshaj plawspawg roj uas muaj kev pheej hmoo(hydrogen, acetylene)
T6= Qhov kub siab tshaj plaws ntawm qhov chaw ≤ 85°C (qhov ntsuas kev nyab xeeb tshaj plaws)
IIIC= Siab tshaj plawspawg neeg muaj kev pheej hmoo plua plav(cov hlau uas ua hluav taws xob zoo li txhuas/magnesium)
Peb licov actuators uas tiv thaiv tau tawgua raws li cov qauv no, kom ntseeg tau tias muaj kev nyab xeeb tshaj plaws.
| Hom | Daim Ntawv Thov | Kev Siv Ib Txwm Muaj |
|---|---|---|
| Tiv taus hluav taws (Ex db) | Cheeb Tsam 1/2 (muaj zog heev) | Cov cav, cov actuators, cov khoom siv hnyav |
| Muaj Kev Nyab Xeeb Sab Hauv (Ex i) | Cheeb Tsam 0 (hluav taws xob tsawg xwb) | Cov chaw tswj hwm, cov sensors |
| Kev Nyab Xeeb-Ua Rau Kom Muaj Kev Nyab Xeeb Ntau Ntxiv (Ex e) | Tsis muaj hluav taws, lub zog nruab nrab | Cov sensors passive, cov thawv sib txuas |
※ Peb cov khoom siv Flameproof (Ex db), zoo tagnrho rau cov ntawv thov kev lag luam muaj zog siabnyob rau hauv Cheeb Tsam 1/2.
ⅡA(Kev pheej hmoo tsawg) - Propane, butane
ⅡB(Kev pheej hmoo nruab nrab) - Ethylene, cov pa roj hauv kev lag luam
ⅡC(Kev pheej hmoo siab tshaj plaws) - Hydrogen, acetylene
IIIA- Cov xov hluav taws kub (paj rwb, ntoo)
IIIB- Cov hmoov av uas tsis ua rau muaj hluav taws xob (hmoov, thee)
IIIC- Cov hmoov av uas ua rau muaj hluav taws xob (aluminium, magnesium)
※ Peb cov khoom siv npog ⅡB, ⅡC (roj) thiab ⅢC (hmoov av) - cov xwm txheej txaus ntshai tshaj plaws.
| Chav Kawm | Qhov Kub Nto Siab Tshaj Plaws. | Cov Xwm Txheej Muaj Kev Pheej Hmoo Siab |
|---|---|---|
| T3 | 200°C | Cov nroj tsuag tshuaj lom neeg uas muaj hydrogen ntau |
| T4 | 135°C | Cov chaw khaws roj, cov chaw cia ether |
| T5 | 100°C | Cov chaw muaj hmoov av uas tsis kub hnyiab |
| T6 | 85°C | Cov chaw kuaj mob, cov khoom sib xyaw hydrogen-cua |
※ Peb cov dampers uas tsis tawg yog T6-rated—qhov siab tshaj plawskev ntsuas kev nyab xeeb rau qhov kub ntawm qhov chaw.
Cheeb Tsam 0- Tsis tu ncuamuaj roj(piv txwv li, sab hauv cov thoob roj)
Cheeb Tsam 1–Ntau zaus muaj roj(piv txwv li, tshuaj reactor, kev ua tiavthaj chaw)
Cheeb Tsam 2–Qee zaumkev pheej hmoo (piv txwv li, kev thauj khoom sab nraum zoovthaj chaws, qhov chaw txij nkawm)
Cheeb Tsam 20- Cov huab cua plua plav tas li (piv txwv li, sab hauv silos)
Cheeb Tsam 21–Kev raug plua plav ntau zaus(piv txwv li, siv txoj siv conveyor)
Cheeb Tsam 22- Kev raug hmoov av tsawg tsawg (piv txwv li, lim dej xau)
※ Peb cov khoom tau ntawv pov thawj rau Cheeb Tsam 1/2 (roj) thiab Cheeb Tsam 21/22 (hmoov av).
Kev tiv thaiv kev tawg tsis yog hais txog kev ua raws li txoj cai xwb - nws yog hais txog lub luag haujlwm. Nrog rau:
• Tiv taus hluav taws Ex dbtsim,
• Cov ntawv pov thawj rauIb puag ncig IIC / IIIC,
• Kev nyab xeeb thermal T6-rated, thiab
• Ua raws liATEX & IECEx
Peb cov actuators uas tsis tawg tau ntseeg siab rau hauv cov xwm txheej hnyav tshaj plaws thoob ntiaj teb.
Tsis txhob ua kom muaj kev cuam tshuam. Hloov kho mus rau qhov kev nyab xeeb uas tau ntawv pov thawj hnub no.
