Ukukhetha indawo ebiyelweyo kubalulekile xa kufikwa ekuqinisekiseni ukhuseleko lweendawo zoshishino, ingakumbi iindawo ezinobungozi. Iindawo ezibiyelweyo ezinobungozi zenzelwe ukukhusela izixhobo zombane kwiigesi eziqhumayo, uthuli kunye nezinye izinto ezingqongileyo. Esi sikhokelo siya kukunceda ukwazi ukuhamba kwiingxaki zokukhetha indawo ebiyelweyo.indawo enobungozi evalekileyooko kulungile kwiimfuno zakho ezithile.
Qonda indawo eyingozi
Ngaphambi kokuba ungene kwinkqubo yokukhetha, kubalulekile ukuqonda ukuba yintoni eyenza indawo enobungozi. Ezi ndawo zahlulwe ngokweegesi ezivuthayo, umphunga okanye uthuli. Iinkqubo zokwahlulahlula zihlala ziquka:
- Indawo 0Indawo apho kukho igesi eqhumayo rhoqo okanye ixesha elide.
- Indawo 1: Indawo apho umoya wegesi oqhumayo unokwenzeka khona ngexesha lokusebenza okuqhelekileyo.
- Indawo yesi-2: Akunakwenzeka ukuba kubekho umoya wegesi oqhumayo ngexesha lokusebenza okuqhelekileyo, kwaye ukuba uyenzeka, uya kubakho ixesha elifutshane kuphela.
Indawo nganye ifuna uhlobo oluthile lwendawo ebiyelweyo ukuqinisekisa ukhuseleko kunye nokuthobela imigaqo.
Izinto Ezibalulekileyo Eziqwalaselweyo Ekukhetheni Iindawo Ezinobungozi
1. Ukukhetha Izinto
Izinto ezikwibhokisi zibalulekile ukuze ihlale ixesha elide kwaye ikhuseleke. Izinto eziqhelekileyo ziquka:
- Yenziwe ngentsimbi eshayinayo: Inika ukumelana nokugqwala okugqwesileyo, ifanelekile kwiindawo ezinobungozi.
- I-aluminiyam: Ilula kwaye ayimelani nokugqwala, kodwa isenokungafaneleki kuzo zonke iindawo ezinobungozi.
- I-Polycarbonate: Inika ukumelana okuhle nokuchaphazeleka kwaye idla ngokusetyenziswa kwiindawo ezingabalulekanga kangako.
Ukukhetha izinto ezifanelekileyo kuya kuxhomekeka kwiingozi ezithile ezikhoyo kwindawo okuyo.
2. Inqanaba loKhuseleko lokungena (IP)
Uvavanyo lwe-IP lubonisa amandla e-enclosure okumelana nothuli kunye nokungena kwamanzi. Kwiindawo ezinobungozi, kufuneka uvavanyo lwe-IP oluphezulu. Khangela i-enclosure enovavanyo lwe-IP lwe-IP65 ubuncinane ukuqinisekisa ukhuseleko kuthuli kunye neejethi zamanzi ezinoxinzelelo oluphantsi.
3. Iindlela ezithintela ukuqhuma
Kukho iindlela ezahlukeneyo zokukhusela ukuqhuma ezikhoyo, kuquka:
- Ayinakuqhuma (Ex d): Yenzelwe ukumelana nokuqhuma ngaphakathi kwindawo ebiyelweyo nokuthintela amalangatye ukuba angaphumi.
- Ukhuseleko oluPhuculweyo (Ex e): Qinisekisa ukuba izixhobo zenzelwe ukunciphisa umngcipheko womlilo.
- Ukhuseleko lwangaphakathi (Umzekelo i): Inciphisa amandla afumanekayo okutsha, nto leyo eyenza ukuba ifaneleke ukusetyenziswa kweZone 0 kunye neZone 1.
Ukuqonda ezi ndlela kuya kukunceda ukhethe indawo evalekileyo ehlangabezana neemfuno ezithile zeendawo ezinobungozi.
4. Ubungakanani kunye noBume
Indawo ebiyelweyo mayibe nobukhulu obufanelekileyo ukuze ikwazi ukuthwala izixhobo ngelixa ivumela umoya ococekileyo kunye nobushushu obucocekileyo. Cinga ngolwakhiwo lofakelo lwakho kwaye uqinisekise ukuba indawo ebiyelweyo ifikeleleka lula ukuze ilungiswe kwaye ihlolwe.
5. Isiqinisekiso kunye nokuthobela imithetho
Qinisekisa ukuba indawo ebiyelweyo iyahlangabezana nemigangatho efanelekileyo kunye neziqinisekiso, ezifana ne-ATEX (yaseYurophu) okanye i-NEC (yaseMelika). Ezi ziqinisekiso zibonisa ukuba indawo ebiyelweyo ivavanyiwe kwaye iyahlangabezana neemfuno zokhuseleko kwiindawo ezinobungozi.
6. Iimeko zokusingqongileyo
Cinga ngeemeko zokusingqongileyo apho ikhabhinethi iza kufakwa khona. Izinto ezifana namaqondo obushushu aphezulu, ukufuma, kunye nokuvezwa kwiikhemikhali zinokuchaphazela ukukhethwa kwezinto ezivalekileyo kunye noyilo.
ukuququmbela
Ukukhetha okuchanekileyoindawo enobungozi evalekileyosisigqibo esibalulekileyo esichaphazela ukhuseleko kunye nokuthobela imithetho kwiindawo zoshishino. Ngokuqwalasela izinto ezinje ngokukhethwa kwezinto, umlinganiselo we-IP, indlela yokukhusela ukuqhuma, ubungakanani, iziqinisekiso kunye neemeko zokusingqongileyo, ungenza ukhetho olunolwazi lokugcina abantu kunye nezixhobo zikhuselekile. Qiniseka ukuba ubonisana nengcali kwaye ulandele imigaqo yendawo ukuqinisekisa ukuba indawo yakho enobungozi iyahlangabezana nayo yonke imigangatho yokhuseleko efunekayo.
