Cov kws tsim txuj ci kev nyab xeeb hauv kev ua tshuaj lom neeg, kev tsim tshuaj, thiab kev tsim roj thiab roj yuav tsum xyuas kom meej tias cov tshuab cua sov tsis dhau los ua cov khoom siv hluav taws xob hauv cov huab cua uas muaj peev xwm tawg tau. Cov cuab yeej siv hluav taws xob tsim hluav taws xob, muaj kev nyab xeeb txaus rau ib puag ncig ib puag ncig, tuaj yeem ua rau muaj kev pheej hmoo tsis txaus ntseeg thaum raug hluav taws xob vapors, combustible dusts, lossis hybrid mixs. Raws li cov ntaub ntawv pov thawj thaj chaw muaj kev phom sij thoob plaws ntau qhov kev lag luam thiab cov txheej txheem tswj hwm thoob ntiaj teb, cov khoom siv hluav taws xob cov khoom siv hluav taws xob nrog tawg -cov khoom siv tiv thaiv thiab cov ntawv pov thawj kev nyab xeeb ua kom cua sov hauv cov cheeb tsam uas cov khoom lag luam tsis tuaj yeem raug cai lossis nyab xeeb nkag.
Cov kev faib thaj chaw muaj kev phom sij, suav nrog European ATEX cov lus qhia thiab North American NEC / CEC cov qauv, txhais cov cheeb tsam raws li qhov tshwm sim thiab lub sijhawm ntawm huab cua tawg. Cheeb tsam 0 lossis Division 1 qhov chaw, qhov chaw muaj kev phom sij muaj nyob tsis tu ncua lossis tsis tu ncua, thov kom muaj kev tiv thaiv siab tshaj plaws nrog rau kev nyab xeeb ntawm sab hauv lossis kev tawg. Cov cua sov kev cai rau cov cheeb tsam no siv hermetically kaw kev tsim kho nrog cov ntaub ntawv pov thawj kev nyab xeeb uas txwv tsis pub muaj hluav taws xob mus rau theem tsis muaj peev xwm ntawm qhov hluav taws xob cov roj sib xyaw. Square- lub taub hau davhlau ya nyob twg configurations pab kom lub kaw enclosures thiab certified terminal blocks tsim nyog rau cov tswv yim tiv thaiv.
Kev tiv thaiv kev tawg, qhov twg lub tshuab cua sov muaj qhov tawg hauv qhov tsis muaj hluav taws xob xa mus rau qhov chaw sab nraud, yuav tsum muaj kev tsim kho kom zoo siv tau los ntawm kev sim hom. Lub zog ntawm lub qhov rooj yuav tsum tiv taus qhov tawg hauv qhov siab yam tsis muaj kev hloov pauv mus tas li, nrog cov nplaim taws ntawm qhov ntev thiab kev tshem tawm uas txias evaporing gases hauv qab qhov kub thiab txias. Kev cai cartridge tso cua sov nrog tuab -cov ntaub thaiv phab ntsa, qhov tseeb- cov khoom sib txuas ua haujlwm, thiab cov ntawv pov thawj cov ntaub ntawv pov thawj tau ua tiav qhov tawg- pov thawj qhov tsim nyog rau thaj tsam 1 daim ntawv thov. Lub ntsiab lus geometric ntawm square- lub taub hau teeb tsa ua kom yooj yim rau kev ua haujlwm zoo thiab sib dhos uas tawg- pov thawj kev tsim kho xav tau.
Intrinsic kev nyab xeeb kev tiv thaiv, nyiam rau Zone 0 daim ntawv thov qhov chaw tawg yog impractical, txwv hluav taws xob lub zog mus rau theem tsis muaj peev xwm ua rau ignition txawm nyob rau hauv qhov teeb meem txhaum cai. Cov cua sov kev cai tsim los rau kev nyab xeeb hauv nruab nrab suav nrog cov khoom siv hluav taws xob tsawg thiab inductance, nrog rau kev tiv thaiv thiab kev ntsuas hluav taws xob xaiv kom muaj kev nyab xeeb zog. Cov cuab yeej sib txuas nrog rau cov teeb meem kev nyab xeeb lossis cov khoom sib cais galvanic, muaj ntawv pov thawj raws li cov tshuab nrog cov cua sov, xyuas kom meej tias cov xwm txheej txhaum cai tsis tuaj yeem xa hluav taws xob txaus ntshai. Cov kev ntsuas hluav taws xob qis feem ntau ntawm kev nyab xeeb, feem ntau qis dua 100 watts, yuav tsum tau ua tib zoo tsim thermal tsim kom ua tiav cov cua sov uas yuav tsum tau muaj nyob rau hauv kev txwv hluav taws xob nyab xeeb.
Plua plav ignition tiv thaiv nyob rau hauv combustible particulate txaus ntshai nyob rau hauv cov khoom noj, kev tsim tshuaj, thiab kev tuav ntaub ntawv. Cov cua sov saum npoo ntawm qhov kub yuav tsum nyob qis dua qhov kub ntawm qhov hluav taws kub ntawm ib puag ncig cov plua plav lossis huab cua, nrog rau kev tiv thaiv ntxiv rau cov plua plav ingress uas tuaj yeem tsim cov smoldering deposits. Cov qauv tsim kev cai suav nrog qhov ntsuas kub ntawm cov cuab yeej txwv tsis pub muaj kev tswj hwm, nrog rau thaj tsam ntawm thaj chaw thiab wattage faib uas tswj qhov kub thiab txias txawm tias muaj kev tswj tsis tau. Enclosure designs nrog IP6X plua plav nruj tiv thaiv plua plav ingress uas tuaj yeem cuam tshuam kev nyab xeeb lub sijhawm.
Cov txheej txheem muab ntawv pov thawj rau cov cua sov hauv cheeb tsam uas muaj kev phom sij yuav tsum tau thib peb -kev sim thiab kev soj ntsuam zoo uas cov khoom lag luam tsis raug. Cov qauv kev sim suav nrog kev tiv thaiv kev tawg, qhov ntsuas kub ntawm qhov chaw, thiab qhov kev ntsuas qhov ua txhaum validates tsim kev nyab xeeb. Kev tsim cov tshuab ua haujlwm zoo nrog kev soj ntsuam txuas ntxiv kom ntseeg tau tias kev tsim khoom muaj ntawv pov thawj tswj kev tsim qauv. Kev tsim kho lub tshuab cua sov rau cov chaw muaj kev phom sij suav nrog cov ntawv pov thawj no ua ib qho tseem ceeb ntawm txoj haujlwm, nrog rau cov ntaub ntawv cov ntaub ntawv uas txhawb nqa cov neeg siv khoom xa tuaj.
Kev teeb tsa thiab kev saib xyuas cov txheej txheem rau cov cua sov hauv cheeb tsam uas muaj kev phom sij yuav tsum muaj kev cob qhia tshwj xeeb thiab cov ntaub ntawv tshaj li kev coj ua lag luam. Kev sib dhos kom raug, kev sib txuas hauv av, thiab kev pov thawj qhov kev thaiv qhov kev xav tau kev txawj ntse uas cov neeg ua haujlwm saib xyuas yuav tsis muaj. Cov chaw tsim khoom siv hluav taws xob muab cov ntawv qhia kev teeb tsa, kev cob qhia, thiab kev saib xyuas cov txheej txheem tshwj xeeb rau cov ntawv pov thawj. Kev tswj cov khoom seem yuav tsum tswj xyuas cov ntawv pov thawj kev ncaj ncees, nrog cov khoom hloov pauv tuaj yeem raug pom zoo tsim.
Daim ntawv thov engineering rau thaj chaw muaj kev puas tsuaj cua sov yuav tsum muaj kev tshuaj xyuas dav dav ntawm cov pa roj lossis plua plav, kev faib cov cheeb tsam, thiab cov txheej txheem cov txheej txheem uas xaiv cov catalog tsis tuaj yeem hais txog. Cov khoom siv hluav taws xob tshwj xeeb ntawm cov txheej txheem cov ntaub ntawv, suav nrog nws pib- qhov kub thiab txias, qhov hluav taws xob tsawg kawg nkaus, thiab qhov kev sim siab tshaj plaws ntawm kev nyab xeeb, qhia txog lub tshuab cua sov. Kev koom ua ke nrog kev ntsuas kev nyab xeeb tag nrho, suav nrog kev ntsuas roj thiab kev kaw thaum muaj xwm txheej ceev, ua kom lub tshuab cua sov ua rau tsis muaj kev cuam tshuam rau qhov chaw nyab xeeb. Kev sib koom ua haujlwm ntawm thaj chaw muaj kev puas tsuaj engineering muab cov kev daws teeb meem cua sov uas ua kom txaus siab rau ob qho tib si thermal kev ua tau zoo thiab kev ua raws li kev nyab xeeb.
Kev ntsuam xyuas kev lag luam ntawm cov khoom siv hluav taws xob tsim hluav taws xob hauv cheeb tsam yuav tsum suav nrog tag nrho cov nqi ntawm kev ua raws cai es tsis yog kev sib piv cov nqi kho vajtse. Cov nqi ntawv pov thawj, kev teeb tsa tshwj xeeb, kev tshuaj xyuas tsis tu ncua, thiab kev lav phib xaub los ntawm qhov xwm txheej kev nyab xeeb tag nrho ua rau kev lag luam hauv lub neej. Cov qauv tsim kev cai uas ua tiav qhov kev nyab xeeb uas yuav tsum tau muaj kev nyab xeeb nrog tsawg kawg ntawm kev ua haujlwm thermal, lossis ua kom yooj yim rau kev teeb tsa thiab kev saib xyuas los ntawm kev txhim kho lub davhlau ya nyob twg, nquag xa cov nqi tag nrho txawm tias tus nqi pib dua.
