Ukukhetha indawo ebiyelweyo ibalulekile xa kufikwa ekuqinisekiseni ukhuseleko lweemeko zoshishino, ingakumbi iindawo ezinobungozi. Iindawo ezivaliweyo eziyingozi ziyilelwe ukukhusela izixhobo zombane kwiigesi eziqhumayo, uthuli kunye nezinye izinto zokusingqongileyo. Esi sikhokelo siya kukunceda ukhangele ubunzima bokukhetha iindawo ebiyelweyo eyingozioko kulungile kwiimfuno zakho ezithile.
Qonda indawo eyingozi
Ngaphambi kokungena kwinkqubo yokhetho, kuyimfuneko ukuqonda ukuba yintoni na indawo enobungozi. Ezi ndawo zihlelwa ngokobukho beegesi ezinokutsha, umphunga okanye uthuli. Iinkqubo zokuhlela ngokuqhelekileyo ziquka:
- Zowuni 0: Indawo apho irhasi eqhumayo ikhona ngokuqhubekayo okanye ixesha elide.
- Indawo yoku-1: Indawo apho umoya werhasi eqhumayo inokuthi yenzeke ngexesha lomsebenzi wesiqhelo.
- Indawo yesi-2: I-atmosphere yerhasi eqhumayo ayinakwenzeka ukuba yenzeke ngexesha lokusebenza okuqhelekileyo, kwaye ukuba iyenzeka, iya kubakho kuphela ixesha elifutshane.
Indawo nganye ifuna uhlobo oluthile lwesivalo ukuze kuqinisekiswe ukhuseleko nokuthobela imigaqo.
Iingqwalasela eziPhambili ekuKhetheni iiNdawo ezibiyelweyo zoMmandla
1. Ukukhethwa kwezinto
Izinto eziphathekayo zetyala zibalulekile ekomelezeni nasekukhuseleni. Izinto eziqhelekileyo ziquka:
- Yenziwe ngentsimbi eshayinayo: Inika ukuxhathisa okugqwesileyo kwe-corrosion, ilungele indawo ezingqongileyo.
- Aluminiyam: Ikhaphukhaphu kunye ne-corrosion-resistant, kodwa ayinakulungela zonke iindawo ezinobungozi.
- Polycarbonate: Inika ukuchasana kwempembelelo elungileyo kwaye iqhele ukusetyenziswa kwiindawo ezinobunzima obuncinci.
Ukukhetha izinto ezifanelekileyo kuya kuxhomekeka kwiingozi ezithile ezikhoyo kwindawo yakho.
2. Inqanaba loKhuseleko lwe-Ingress (IP).
Ukalo lwe-IP lubonisa ukukwazi kwendawo ebiyelweyo ukuxhathisa uthuli kunye nokungena kwamanzi. Kwiindawo ezinobungozi, umgangatho ophezulu we-IP uyafuneka. Jonga indawo ebiyelweyo enomlinganiselo we-IP ubuncinci be-IP65 ukuqinisekisa ukhuseleko eluthulini kunye neejethi zamanzi ezinoxinzelelo oluphantsi.
3. Iindlela zobungqina bokudubula
Kukho iindlela ezahlukeneyo zokukhusela ugqabhuko-dubulo ezikhoyo, kuquka:
- Ingaqhubi (Ex d): Yenzelwe ukumelana nokudubula ngaphakathi kwendawo ebiyelweyo kwaye ithintele amadangatye ukuba angaphumi.
- Ukhuseleko oluphuculweyo (Eks e): Qinisekisa ukuba izixhobo ziyilelwe ukunciphisa umngcipheko womlilo.
- Ukhuseleko lwangaphakathi (Eks i): Inciphisa amandla akhoyo okulayita, iwenza afaneleke usetyenziso lweZone 0 kunye neZone 1.
Ukuqonda ezi ndlela kuya kukunceda ukhethe indawo ebiyelweyo ehlangabezana neemfuno ezithile zeendawo ezinobungozi.
4. Ubungakanani kunye noqwalaselo
Indawo ebiyelweyo kufuneka ilinganiswe ukulungiselela isixhobo ngelixa ivumela ukungena komoya okufanelekileyo kunye nokutshatyalaliswa kobushushu. Qwalasela uyilo lofakelo lwakho kwaye uqinisekise ukuba indawo ebiyelweyo ifikeleleka ngokulula ukulungiselela ukugcinwa nokuhlolwa.
5. Izatifikethi kunye nokuThobela
Qinisekisa ukuba i-enclosure ihlangabezana nemigangatho efanelekileyo kunye neziqinisekiso, ezifana ne-ATEX (yeYurophu) okanye i-NEC (ye-United States). Ezi ziqinisekiso zibonisa ukuba indawo ebiyelweyo ivavanyiwe kwaye iyahlangabezana neemfuno zokhuseleko kwiindawo eziyingozi.
6. Iimeko zokusingqongileyo
Cinga ngeemeko zokusingqongileyo apho ikhabhinethi iya kufakwa. Izinto ezinje ngamaqondo obushushu agqithisileyo, ukufuma, kunye nokuvezwa kwemichiza kunokuphembelela ukukhethwa kwezinto ezivalelekileyo kunye noyilo.
ukuququmbela
Ukukhetha okulungileyoindawo ebiyelweyo eyingozisisigqibo esibalulekileyo esichaphazela ukhuseleko kunye nokuthotyelwa kweemeko zoshishino. Ngokuqwalasela izinto ezifana nokukhethwa kwezinto, ukukala kwe-IP, indlela yokukhusela ukuqhuma, ubungakanani, izatifikethi kunye neemeko zokusingqongileyo, unokwenza ukhetho olunolwazi lokugcina abantu kunye nezixhobo zikhuselekile. Qinisekisa ukuba udibana nengcali kwaye ulandele imimiselo yendawo ukuqinisekisa ukuba indawo yakho enobungozi ihlangabezana nayo yonke imigangatho yokhuseleko oluyimfuneko.
