Shenhai Explosion-Ubungqina
I “Eks” ekuqaleni kokumakishwa kobungqina bokudubula ngokupheleleyo kubonisa ukuba yeyohlobo oluthile lwesixhobo sokuthintela uqhushumbo., ukanti ayinikeli zinkcukacha ngeempawu zayo ezithile ezinobungqina bokudubula.
Iimpawu ze-Explosion-Proof Electrical Equipment
| Uhlobo | Uhlobo lobungqina bokudubula | Uhlobo loKhuseleko olongezelelweyo | Uhlobo loKhuseleko lwangaphakathi | Uhlobo loxinzelelo olulungileyo | I-Oli ezaliswe Uhlobo | Ukungunda okugcwele isanti | Uhlobo lwasimahla lwentlantsi | Exm | Uhlobo olungangeni |
|---|---|---|---|---|---|---|---|---|---|
| Sayina | d | e | ia kunye ib | p | o | q | n | m | h |
Olu phawu lubonisa ngenkqubo uhlobo lobungqina bokudubula, inqanaba, kunye nodidi. Njengokuba:
Ex d ii ibhekisa kwiKlasi II, Inqanaba B, Iqela le-T3 isixhobo sombane esingatshiyo;
Ex ia II AT5 ibonisa iClass II, Inqanaba A, Iqela le-T5 inqanaba lesixhobo sombane esikhuselekileyo;
Ex ep II BT4 imisela uhlobo lokhuseleko olongezelelweyo isixhobo sombane esinamalungu acinezelekileyo ukuze kukhuselwe ugqabhuko-dubulo;
Exd II (NH3) okanye Ex d II ammonia ichonga a ingatshi isixhobo sombane esilungiselelwe iindawo zegesi ye-helium;
Ex d Imele isixhobo sombane esingangenwa lidangatye esixelwe kuKlasi I;
I-Ex d/II BT4 ibonisa isixhobo sombane esingatshiyo esisebenza kuzo zombini iClass I kunye neClass II, Inqanaba B, Iqela T4.
Izixhobo zombane ezikwaziyo ukumelana nothuli ziphawulwe nge-DIP (Ubungqina bokuvutha kothuli) uphawu. Imizekelo ibandakanya:
I-DIP A20 kunye ne-DIP A21, kudidi A lwezixhobo ezikhusela uthuli kwiiZowuni 20 kwaye 21, ngokulandelelanayo;
I-DIP A22 yoHlobo A lwesixhobo sokuthintela ukuqhuma uthuli kwiZowuni 22;
I-DIP B22 yoHlobo lwe-B isixhobo sokuthintela ukuqhuma kothuli kwiZowuni 22, phakathi kwabanye.
