Xa kuziwa kwiimeko ezineegesi eziguqukayo kunye nezinto ezinokutsha, ukhuseleko alukhethi-lubalulekile. Izityalo zePetrochemical zisebenza kwezinye iimeko eziyingozi kakhulu, apho i-spark enye ingakhokelela kwimiphumo eyingozi. Yiyo loo nto kanye ukukhetha indawo ebiyelweyo ye-EJB yezityalo zepetrochemical kubalulekile kwimisebenzi ekhuselekileyo nesebenzayo.
Iindawo ezivaliweyo ze-EJB ezinobungqina bokudubula zibonelela ngomqobo othembekileyo ngokuchasene nemithombo enokuba khona yokutshisa, inceda ukukhusela abasebenzi kunye nezixhobo. Kodwa yintoni eyenza ezi zivalo zisebenze ngolu hlobo—kwaye yintoni ofanele uyijonge xa ukhetha enye?
Yintoni eyenza iEJB ebiyelweyoIlungele iZibonelelo zePetrochemical?
Ayizizo zonke iindawo ezivaliweyo zombane ezifanelekileyo kwindawo ezinobungozi. Indawo ebiyelweyo ye-EJB yezityalo zepetrochemical yenzelwe ngokukodwa ukuqulatha uqhushumbo lwangaphakathi kunye nokuthintela iintlantsi ekuvutheni iigesi ezingqongileyo. Ezi zivalo ziqhele ukwakhiwa ukusuka kwizinto ezinokuqina okuphezulu njenge-aluminium alloy okanye insimbi engenasici kwaye zivavanywa ngokungqongqo ukuhlangabezana nemigangatho yokhuseleko yamazwe ngamazwe efana ne-ATEX, IECEx, okanye i-NEC.
Uyilo luqinisekisa ukuba naluphi na ugqabhuko-dubulo olwenzeka ngaphakathi kwendawo ebiyelweyo luqulethwe, ngelixa lukhusela izinto eziyingozi zangaphandle ukuba zingangeni. Olu khuselo lunemigangatho emibini lubalulekile ekugcineni ukuthotyelwa kunye nokhuseleko kwiindawo ezinoqhushumbo.
Iimpawu eziphambili omawuzijonge kwindawo ebiyelweyo ye-EJB ekwiMgangatho oPhezulu
Ukukhetha indawo ebiyelweyo ye-EJB ifuna okungaphezulu kunokuphawula nje ibhokisi yesiqinisekiso sokhuseleko. Kuya kufuneka uvavanye iimpawu ezithile ezichaphazela ngokuthe ngqo ukusebenza kwiisetingi zepetrochemical:
Uyilo lwe-flameproof: Iqinisekisa ii-arcs zangaphakathi okanye uqhushumbo aluyi kutshisa umoya ongqongileyo.
I-Corrosion Resistance: Ibalulekile kufakelo lwangaphandle okanye lwaselwandle oluvezwe kwiikhemikhali okanye ukufuma.
I-Flexible Component Mounting: Ivumela ukudityaniswa kokutshintsha, iitheminali, okanye ii-breaker circuit.
Ukulula kokuLondolozwa: Uyilo olulungele intsimi lunciphisa ixesha lokuphumla kwaye lwenza lula uhlolo.
Ukwenziwa ngokwezifiso: Ezinye iindawo ezivaliweyo zibonelela ngemodyuli ukuhlangabezana neemfuno ezithile zeepaneli zolawulo okanye iibhokisi zokuhlangana.
Ngalunye lwezi mpawu lunegalelo ekwenzeni indawo ebiyelweyo ye-EJB yezityalo zepetrochemical ezingakhuselekanga kuphela, kodwa zikwathembekile kwaye zihlala ixesha elide.
Usetyenziso oluqhelekileyo kwiiNdawo zePetrochemical
Ukusuka kwizixhobo zombane ezingaselunxwemeni ukuya kwiiyunithi zokusetyenzwa kwerhasi, iindawo ezivalelekileyo ze-EJB zihlala zisetyenziselwa ukubeka izinto ezibalulekileyo zombane kwiindawo ezithanda ukudubula. Zikhusela amacandelo anjengokutshintsha kolawulo, iireyiyi, kunye neebhloko zetheminali, zenza ukuba abaqhubi balawule kwaye babeke iliso kwimisebenzi ebalulekileyo ngaphandle kokubeka esichengeni ukhuseleko.
Nokuba zixhonywe ezindongeni okanye kwiiyunithi zokutyibiliza, ezi zivalo zidlala indima ebalulekileyo ekunciphiseni umngcipheko womlilo nokuqinisekisa ukuqhubeka kwiimeko ezinzima zoshishino.
IiNdlela eziGqwesileyo zokuFakelo kunye noLondolozo
Nezona zixhobo zibalaseleyo aziyi kusebenza kakuhle ukuba azifakwanga okanye azigcinwanga kakuhle. Nanga amanye amacebiso abalulekileyo:
Yenza ulwahlulo olululo lwendawo phambi kofakelo ukuze utshatise indawo ebiyelweyo kunye nomlinganiselo wendawo.
Landela imilinganiselo yetorque yazo zonke iziqhoboshi ukuze ugcine ingqibelelo engatshiyo.
Vala onke amangeno entambo kunye namadlala avunyiweyo ukuthintela ukungena kweegesi okanye ukufuma.
Hlola rhoqo iimpawu zokubola, ukuguga, okanye ukonakaliswa kwetywina kunye nezixhobo.
Gcina amaxwebhu ehlaziywa ngokuthotyelwa kwemigaqo kunye nophicotho lwexesha elizayo.
Ngokulandela olu qheliselo, uqinisekisa umsebenzi opheleleyo okhuselayo wendawo ebiyelweyo ye-EJB yezityalo zepetrochemical uhlala unjalo ekuhambeni kwexesha.
Khetha uKhuseleko, Khetha ukuthembeka
Kumashishini ayingozi, onke amacandelo abalulekile-kunye nokukhetha indawo ebiyelweyo ye-EJB inokuthetha umahluko phakathi kwemisebenzi yesiqhelo kunye nesehlo sokhuseleko. Kwiimeko zepetrochemical apho ingozi ihlala ikhona, i-enclosure eyenziwe kakuhle ngumgcini othuleyo oqinisekisa ukusebenza kakuhle, okungaphazamisekiyo.
Ngaba ufuna uncedo lokukhetha isisombululo esifanelekileyo sokudubula kwindawo yakho?
Sunleemilapha ukuxhasa iinjongo zakho zokhuseleko kunye nezivalo ezithembekileyo, ezivavanyiweyo, nezithobelayo ezenzelwe usetyenziso lwepetrochemical. Qhagamshelana nathi namhlanje ukuze ufumane iingcebiso zengcali kwiprojekthi yakho elandelayo.
