Shenhai Explosion-Proof
Hom tawg-pov thawj:
Txoj kev tawg-pov thawj ntawm kev nyab xeeb ntxiv (Ex thiab) thiab flameproof (Ex d) enclosures txawv heev.
Hom Flameproof:
Txoj kev flameproof suav nrog cov khoom siv uas yuav tsim cov arcs lossis sparks thaum lub sijhawm ua haujlwm ib txwm nyob hauv ib lub thawv uas muaj zog. Qhov no enclosure tiv thaiv tawg siab tsis muaj kev puas tsuaj, xyuas kom meej tias cov nplaim taws thiab qhov kub siab txaus ntshai uas tsim los ntawm kev tawg hauv sab hauv tsis hloov mus rau sab nraud. Nws xyuas kom meej tias cov no yog extinguished thiab txias thaum dhau los ntawm kev sib koom ua ke flameproof, tiv thaiv ignition ntawm tawg gases sab nraum lub enclosure.
Ntau hom kev nyab xeeb:
Hauv nce kev nyab xeeb (Ex thiab) cov ntaub thaiv npog, tsis muaj kev tsim tawm ntawm qhov hluav taws xob lossis kub kub txaus ntshai thaum lub sijhawm ua haujlwm ib txwm muaj. Kev ntsuas ntxiv raug coj los txhim kho kev nyab xeeb thiab kev ntseeg tau.
Ntsia hlau:
Yog vim li cas thiaj muaj ntau screws nyob rau hauv flameproof cov ntaub thaiv npog, tab sis tsis nyob hauv ntau hom kev nyab xeeb?
Flameproof enclosures yuav tsum muaj qib siab ntawm qhov tseeb hauv lawv qhov sib txawv kom tiv thaiv kev tawg sab hauv los ntawm igniting sab nraud explosive gases. Ntau cov ntsia hlau ua kom cov seams nruj dua thiab muaj kev nyab xeeb dua. Qhov no yog vim li cas flameproof enclosures muaj ntau yam screws.
Ntxiv kev nyab xeeb tsom rau qib tiv thaiv. Kev sib khi zoo nrog tsuas yog plaub lub screws txaus.
Cheebtsam:
Flameproof enclosures tsis txwv rau cov khoom siv sab hauv vim lawv tuaj yeem tiv taus ib qho arcs lossis sparks hauv. Ntev npaum li lub plhaub sab nraud tuaj yeem tiv taus qhov tawg siab yam tsis muaj kev puas tsuaj, Nws xyuas kom meej tias cov nplaim hluav taws kub thiab qhov kub thiab txias tsim tawm sab hauv raug tua thiab txias thaum dhau los ntawm qhov sib koom ua ke flameproof, tiv thaiv sab nraud ignition.
Ua kom muaj kev ruaj ntseg enclosures yuav tsum xub xyuas kom meej tias cov khoom siv sab hauv tsis tsim cov txim taws, txaus ntshai kub, lub arcs. Cov kev tiv thaiv ntxiv yog tom qab ntawd los txhim kho kev nyab xeeb thiab kev ntseeg tau.
Kev sib haum xeeb:
Piv txwv li, lub Circuit Court breaker tsim los rau cov ntaub thaiv npog tsis tuaj yeem siv rau hauv qhov chaw ruaj ntseg ntxiv. Txawm li cas los, converting ib qho kev ruaj ntseg enclosure rau ib tug flameproof yog tso cai.
Yog li ntawd, hom kev tawg-pov thawj tsim nyog yuav tsum raug xaiv raws li qhov xav tau tiag tiag, thiab kev hloov pauv yuav tsum tsis txhob ua tsis tu ncua.
