Dab tsi yog Pawg Kub Kub ntawm Cov Khoom Siv Hluav Taws Xob Hluav Taws Xob Hluav Taws Xob

Kev faib tawm qhov kub thiab txias yog qhov tseem ceeb rau kev ntsuas kev nyab xeeb rau kev ntsuas lub peev xwm ntawm qhov hluav taws kub ntawm cov pa taws thiab cov khoom siv hluav taws xob tawg.. Flammable gases tau muab faib ua rau hauv chav kawm raws li lawv qhov kub thiab txias, thaum cov khoom siv hluav taws xob tau muab faib ua rau 6 pawg raws li lawv qhov kub siab tshaj plaws saum npoo av, npe T1, T2, T3, T4, T5, thiab T6. Txawm li cas los, cov txheej txheem rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob yog qhov sib txawv.

Kub Group	Ignition Kub ntawm Combustible Gas / ℃	Cov cuab yeej siv siab qhov kub thiab txias T / ℃
T1	t ≥450	450≥ 300
T2	450≥300	300≥ t 200
T3	300≥ 200	200≥ 135
T4	200≥135	135≥ t 100
T5	135≥ 100	100≥ 85
T6	100t 85	85≥ t

Lub hauv paus ntsiab lus ntawm cov khoom siv hluav taws xob kub Kev faib tawm yog tias qhov kub siab tshaj plaws ntawm qhov chaw tsim los ntawm cov cuab yeej yuav tsum tsis txhob cuam tshuam cov nplaim hluav taws kub. Hauv lwm lo lus, cov khoom siv qhov siab tshaj plaws saum npoo yuav tsum tsis pub tshaj qhov kub ntawm qhov hluav taws kub nplaim taws cov pa.

Nws yog ib qho tseem ceeb kom nco ntsoov tias qhov siab tshaj plaws saum npoo ntawm Cov khoom siv hluav taws xob tawg hais txog qhov kub siab tshaj plaws uas tuaj yeem ncav cuag ntawm nws qhov chaw lossis qhov chaw nyob rau hauv ib txwm ua haujlwm thiab nyob rau hauv cov xwm txheej tsis zoo tshaj plaws tau pom zoo. Qhov kub no yuav tsum muaj peev xwm igniting ib puag ncig tawg gas-air sib tov.

Vim muaj kev sib txawv tawg-pov thawj tsim, qhov siab tshaj plaws saum npoo tuaj yeem xa mus rau qhov sib txawv ntawm cov khoom siv. Tej zaum nws yuav yog qhov kub ntawm qhov chaw sab nrauv ntawm lub qhov rooj, xws li cov khoom siv hluav taws xob flameproof, los yog nws tuaj yeem yog qhov kub ntawm qhov chaw sab nraud ntawm cov cuab yeej siv los yog qee yam khoom siv sab hauv, zoo li hauv nce kev nyab xeeb los yog cov khoom siv hluav taws xob siab.
