Shenhai Explosion-Proof
Cov ntaub ntawv pov thawj tawg tau muab faib ua IIA, IIB, thiab IIC, nrog IIC yog qib siab tshaj plaws, ua raws li IIB thiab IIA.
| Hom mob | Gas Classification | Cov pa hluav taws xob | Yam tsawg kawg nkaus Ignition Spark Zog |
|---|---|---|---|
| Sub Kuv | Kuv | Methane | 0.280mJ |
| Factories sab nraum lub Mine | IIA | Propane | 0.180mJ |
| IIB | Ethylene | 0.060mJ | |
| IIC | Hydrogen | 0.019mJ |
Tsis ntev los no, tus neeg siv khoom nug txog peb lub tuam txhab cov khoom tawg-pov thawj. Kuv paub tseeb tias nws yog IIC. Thaum nws nug seb nws puas ua tau raws li IIB cov cai uas nws xav tau, Kuv tau lees paub nws tias IIC yog tus qauv siab tshaj plaws ntawm kev faib cov pov thawj tawg thiab ua tiav cov kev xav tau. Ntxiv nrog rau kev siv mining, Cov ntaub ntawv pov thawj tawg muaj xws li IIA, IIB, thiab IIC, nrog IIC yog cov khoom lag luam zoo tshaj plaws.
Cov neeg tsim khoom ntawm kev tawg-pov thawj teeb pom kev zoo feem ntau xaiv cov qib siab tshaj plaws (yuav tsum tau ntawv pov thawj), zoo ib yam li lub teeb 300W tuaj yeem hloov tau cov wattage qis dua. Kev kawm tsav tsheb txhais tau tias koj tuaj yeem ua haujlwm ob qho tib si phau ntawv thiab tsis siv neeg tsheb. Cov uas kawm tsis siv neeg raug txwv rau cov tsheb tsis siv neeg, qeb qis tshaj. Qhov kev sib piv no yuav tsum nkag siab rau txhua tus.
Ntau tus neeg siv thiab cov neeg siv khoom xav tias tsuas yog cov khoom lag luam nrog cov kev ntsuas tawg-pov thawj yog siv tau. Qee tus pom lawv tau yuav cov khoom IIC es tsis yog IIB, uas yuav tsum tsis txhob txhawj, raws li IIC yog superior rau IIB thiab tuaj yeem siv nrog kev ntseeg siab.
Txawm li cas los, rov qab tsis muaj tseeb. Piv txwv li, IIB-rated LED tawg-pov thawj teeb nyob rau hauv cov roj depot tsis txaus; tsuas yog IIC-rated teeb txaus.
