Qhov txawv ntawm Explosion-Proof theem IIC thiab IIB

Explosion-proof classifications faib ua IIA, IIB, thiab IIC, Nrog IIC yog qib siab, raws li IIB thiab IIA.

Qeb	Roj Classification	Cov neeg sawv cev gases	Yam tsawg kawg yog Ignition spark zog
Nyob rau hauv lub mine	Kuv	methane	0.280mJ
Factories sab nraum lub Mine	IIA	Propane	0.180mJ
	IIB	Ethylene	0.060mJ
	IIC	hydrogen	0.019mJ

Ntua, Ib tug neeg nug txog peb lub tuam txhab tawg-proof classifications. Kuv paub tseeb hais tias nws yog IIC. Thaum nws nug txog yog hais tias nws tau ntsib tus IIB yuav tsum tau nws xav tau, Kuv assured nws tias IIC yog tus txheem ntau tshaj ntawm explosion-proof classification thiab siab txaus siab rau qhov yuav tsum tau. Aside ntawm tsuas siv ntaub ntawv, tawg-prof classifications muaj xws li IIA, IIB, thiab IIC, Nrog IIC nyob saum-nyob saum-nyob khoom.

Manufacturers ntawm explosion-proof teeb feem ntau xaiv qib siab (yuav tsum muaj daim ntawv pov thawj zov me nyuam), akin to ib 300W lamp tau hloov tej wattage tsawg dua wattage. Kev kawm tsav manual txhais tau tias koj yuav khiav lag luam ob yam manual thiab tsheb khiav tsheb. Cov neeg uas kawm tau txwv tsis pub muaj tsheb, qeb qeb. No analogy yuav tsum to taub rau tag nrho.

Muaj coob tus neeg thiab cov neeg muas zaub xav tias tsuas khoom uas matching explosion-proof ntsuam xyuas yog siv. Ib txhia nrhiav tau lawv muaj muas ib qho khoom IIC tsis txhob SIV IIB, uas yuav tsum tsis muaj kev txhawj xeeb, Raws li IIC yog superior rau IIB thiab yuav siv tau cov qoob loo.

tiam sis, nraud tsis muaj tseeb. Piv txwv, IIB-nyob LED tawg-pov thawj teeb nyob rau hauv ib cov roj depot yog insufficient; Tsuas yog IIC-rated teeb yog tsim nyog.
