Los ntawm qhov kub thiab txias mus rau qhov chaw tawg thiab tawg, cov khoom siv hluav taws xob sib txuas siv hauv cov roj thiab roj siv tau ntsib ntau yam teeb meem. Yog li, dab tsi yuav tsum xav txog thaum xaiv cov khoom sib txuas uas tuaj yeem kov yeej cov teeb meem no thiab ua kom cov ntawv thov no khiav ntawm qhov ua tau zoo tshaj plaws?
Qhov xwm txheej puag ncig
Thaum xaiv ib lub connector, thawj qhov yuav tsum tau xav txog yog qhov sib txawv ntawm cov khoom sib txuas yuav raug siv.
In the Dangerous Substances and Explosive Atmospheres Regulations 2002 (DSEAR), Zone 0 is defined as a persistently explosive atmosphere, Zone 1 means a frequently present explosive atmosphere, and Zone 2 means a rarely explosive atmosphere. The UK Health and Safety Executive (HSE) explained that "the main purpose of zoning is to facilitate the correct selection and installation of equipment for safe use in that environment, taking into account the properties of the flammable materials that will be present."
Qhov phem tshaj plaws, yog tias qhov tam sim no los ntawm cov khoom sib txuas los ntawm kev sib cuag nrog cov kua dej thiab cov pa hluav taws xob hauv ib puag ncig, nws tuaj yeem dhau los ua qhov hluav taws kub. Yog li ntawd, tag nrho cov connectors siv nyob rau hauv cov huab cua tawg yuav tsum ua raws li IECEx thoob ntiaj teb tus qauv, uas tswj cov installation thiab siv cov khoom siv hluav taws xob nyob rau hauv cov cheeb tsam no.
Connector Nta
Tom ntej no, xav txog tej yam ntxiv uas tuaj yeem txhim kho kev ua tau zoo. Piv txwv li, kev tso hluav taws xob rau lub kaw lus kom tsis txhob cuam tshuam cov cuab yeej (tej zaum nyob rau hauv ib puag ncig txaus ntshai) tuaj yeem yog lub sijhawm- siv thiab cuam tshuam tsis zoo rau kev tsim khoom. Qhov no tuaj yeem kov yeej los ntawm kev txhim kho cov khoom sib txuas nrog lub peev xwm thermal disconnect, tso cai rau cov neeg siv khoom sib txuas thiab rov txuas cov khoom siv yam tsis tau kaw tag nrho.
Lwm txoj hauv kev los ua kom muaj txiaj ntsig zoo tshaj plaws yog xav txog qhov yooj yim thiab ceev ntawm kev sib txuas ntawm cov khoom sib txuas. PEI-Chivkeeb muaj cov khoom sib txuas uas tuaj yeem tiv taus cov kev cov nyom ntawm kev lag luam roj thiab roj, xws li Trolex Falcon 25 series, uas paub txog nws ceev - mating thiab locking mechanisms uas siv sijhawm ob peb feeb xwb ua ke. Lub tuam txhab tseem yog ATEX certified assembler rau Amphenol Star-Line EX thiab Amphe-Ex, uas yog ib qho ntawm cov khoom siv roj thiab roj uas nyiam tshaj plaws vim lawv cov qauv tsim rugged thiab plethora ntawm configuration xaiv.
