Shenhai Explosion-Proof
Scope ntawm daim ntawv thov:
Tsuas tso, “tawg-pov thawj” teeb pom kev zoo yog ib hom khoom siv hluav taws xob tawg uas siv rau hauv thaj chaw uas muaj kev phom sij tawg. Cov cheeb tsam zoo li no yog tus cwj pwm los ntawm qhov muaj cov pa taws kub hnyiab, vapors, los yog plua plav hauv huab cua. Cov khoom siv hluav taws xob tau teeb tsa thiab siv nyob rau hauv cov cheeb tsam no yuav tsum ua kom tau raws li qhov yuav tsum tau ua ntawm cov “Code rau kev tsim hluav taws xob kev teeb tsa nyob rau hauv Explosive and Fire Hazardous Environments” (GB50058).
Yog vim li cas thiaj tsim nyog:
Ntau qhov chaw tsim khoom tsim cov khoom siv hluav taws xob. Kwv yees li ob feem peb ntawm thaj chaw hauv cov mines thee yog qhov ua rau tawg; hauv kev lag luam chemical, dhau 80% ntawm cov chaw tsim khoom yog tawg. Oxygen yog omnipresent nyob rau hauv cov huab cua. Ignition qhov chaw los ntawm kev siv ntau yam khoom siv hluav taws xob, txhuam txhuam, mechanical hnav sparks, static sparks, thiab kub kub yog inevitable, tshwj xeeb tshaj yog thaum cov twj paj nruag thiab hluav taws xob ua haujlwm tsis zoo.
Lub hom phiaj, ntau qhov chaw ua lag luam ua tau raws li cov xwm txheej rau kev tawg. Thaum lub concentration ntawm cov khoom tawg nyob rau hauv cov huab cua mus txog qhov kev txwv explosive thiab muaj ib tug ignition qhov chaw., Kev tawg tuaj yeem tshwm sim. Li no, qhov tsim nyog rau kev ntsuas tawg-pov thawj yuav tshwm sim.
Nqi-zoo:
Ib qho laj thawj tseem ceeb uas tib neeg tsis kam siv cov teeb pom kev tawg yog lawv cov nqi. Txawm li cas los, cov ncauj lus kom ntxaws tus nqi-cov txiaj ntsig kev tsom xam piv cov teeb pom kev zoo tib yam nrog cov teeb pom kev tawg qhia tias tom kawg muaj lub neej ntev dua.. Thaum lub teeb incandescent tej zaum yuav pheej yig dua pib, lawv lub neej luv luv thiab kev hloov pauv tsis tu ncua yuav raug nqi kho ntau dua. Yog li ntawd, tag nrho cov nqi-zoo ntawm tawg-pov thawj teeb yog ntau dua li cov teeb incandescent.
