Iimveliso
Ibhokisi evalekileyo yentsimbi ye-ATEX enobungqina bokudubula
Ingcaciso yeMveliso
Ubungqina bokudubula (nabo bubungqina bokudubula) yenziwe ngokuqinileyo kwiibhokisi zesiphambuka ukuze zisetyenziswe kwiindawo eziyingozi.Bagcina amacandelo ombane awahlukeneyo afana nala: iibhloko zetheminali, iiswitshi, iziguquli, iireyilayi kunye nezinye izixhobo ze-arching & sparking.Ezi bhokisi zenziwe ngobunjineli ukuba ziqulathe ugqabhuko-dubulo lwangaphakathi olusuka kwiigesi, umphunga, uthuli kunye neentsinga ukuze kugcinwe umoya ongqongileyo okhuselekileyo.Ziyakwazi ukumelana ne-corrosion kwaye zigcina ukunyamezela okuphezulu kumaqondo obushushu agqithisileyo.Ezi zivalo zingatshiyo zisisombululo esifanelekileyo kwiindawo ezinobungozi.Ukuba bubungqina bokuqhuma, baya kuqulatha naluphi na ukuqhuma kwangaphakathi ukusuka ekusasazeni kwindawo yangaphandle, ngaloo ndlela kuthintele ukulimala kunye nokulimala kwepropati.
Iindawo eziyingozi ezikhusela ugqabhuko-dubulo kunye nezivalo ezingatshiyo zihlelwa ngokwemilinganiselo eyahlukeneyo yokhuseleko, ngokuxhomekeke kwindawo kunye nenqanaba lokhuseleko ezinikezelayo.Olu vavanyo lusekwe kwimigangatho yoMbutho weSizwe waBavelisi boMbane (NEMA), kunye nomgangatho wamazwe ngamazwe we-EN 60529 woKhuseleko lokuNgena (IP) olubonisa umgangatho wokhuseleko kwiingozi zombane ezinjengomhlwa, uthuli, imvula, ukutshiza kunye namanzi aqondiswe ngombhobho. kunye nokwakheka komkhenkce.
Iindawo ezivalekileyo ezikhusela uqhushumbo ziyilwe zinemisonto eyandisiweyo enemisonto aphole kwaye iqulathe ugqabhuko-dubulo ngaphakathi kwendawo ebiyelweyo.Ngoko ke, nayiphi na i-arc yombane enokuthi yenzeke ayiyi kusasazwa kwi-atmosphere yangaphandle eqhumayo.
● Ikhuselekile kwaye ithembekile kwiatmosfera eqhumayo.
● Indawo ebiyelweyo engenakudubula inceda bonke abantu abasebenza kwindawo eyingozi ukuba bahlale bekhuselekile xa kuvele ingozi.Kwakhona kunciphisa umonakalo onokwenzeka.
● Izinto ezisetyenziswa kwindawo ebiyelweyo yomelela.Inokumelana nempembelelo ephezulu.
● Ihambisana neyona migangatho iphezulu yokhuseleko.
● Inomgangatho ophezulu wokukhusela.
