- Ukuthobela: Baqinisekisa ukuba imveliso ihlangabezana neemfuno zolawulo lwemimandla ethile okanye amashishini.
- Ubuchule: Ngokuqonda le miqondiso, abathengi banokukhawuleza ukuchonga iimveliso ezihambelana neemfuno zabo zokusebenza, ukuphepha iimpazamo ezibizayo.
IiMpawu zoKhanya eziQhelekileyo eziBonekayo zichaziwe
Ulwahlulo lweNdawo (iZowuni okanye udidi/iCandelo)
Iindawo ezinobungozi zihlelwa ngokusekwe kumathuba kunye nokuphindaphindeka kwemimoya eqhumayo:
- Inkqubo yendawo (iMigangatho yamazwe ngamazwe njenge-IECEx, i-ATEX):
- Ummandla 0: Irhasi eqhumayo ikhona rhoqo (umzekelo, ngaphakathi kwiitanki zokugcina itanki yeoli).
- Ummandla 1: Irhasi eqhumayo inokwenzeka ngexesha lomsebenzi wesiqhelo (umzekelo, kufutshane nezikhululo zamafutha).
- Ummandla 2: Irhasi eqhumayo yenzeke kuphela phantsi kweemeko ezingaqhelekanga (umz., amagumbi enjini angenawo umoya kakuhle).
- Udidi/iNkqubo yoLwahlulo (iMigangatho yaseMntla Melika njenge-NEC):
- Udidi I, iCandelo 1: Iigesi ezinokutsha okanye umphunga zihlala zikhona.
- Udidi II, iCandelo 2: Uthuli oluvuthayo lubakho ngamaxesha athile.
Icebiso Pro: Xa ukhetha izibane zommandla waselwandle, qwalasela iindawo ezithile kwinqanawa yakho. Umzekelo, iitanki zeoyile zihlala zifuna izibane ezikayithwe nguZone 0 kwiindawo zokugcina ngenxa yokuvezwa rhoqo kwiigesi eziqhumayo.
Iqondo lobushushu (T-Class)
Iqondo lobushushu libonisa obona bushushu bomphezulu bomphezulu bendawo yokukhanya xa kuthelekiswa nobushushu bokutshisa bezinto ezingqongileyo:
- T1 (450°C okanye ngaphezulu): Ilungele izinto ezinobushushu obuphezulu bokutshisa.
- I-T6 (85°C okanye ngaphantsi): Ilungele iindawo ezinobushushu obuphantsi bokutshisa.
Umzekelo: Kwigumbi leenjini yenqanawa, apho iigesi ezinokutsha zinokuba neendawo ezisezantsi zokutshisa, izibane ezinomlinganiselo we-T6 zibalulekile ukunqanda ukuvutha ngempazamo.
Umlinganiselo we-IP (uKhuseleko lokuNgena)
Ukulinganiswa kwe-IP chaza ukuxhathisa kwemveliso kumasuntswana aqinileyo kunye nolwelo:
- IP66: Iqinile uthuli ngokupheleleyo kwaye iyaxhathisa kwiijethi zamanzi ezinamandla.
- IP67: Ayinathuli kwaye iyakwazi ukuntywiliselwa okwexeshana emanzini.
Isizathu sokuba Kubalulekile: Imo engqongileyo yaselwandle ibeka izibane kwisitshizi setyuwa, ukufuma, kunye nokuchaphaza ngamaxesha athile. IP66 okanye IP67 ratings iqinisekisa ukuqina kunye nokuthembeka phantsi kwezi meko.
Amanqaku eSiqinisekiso
Amanqaku esiqinisekiso aqinisekisa ukuthotyelwa kwemveliso nemigangatho yokhuseleko:
- IECEx: Yaziwa kwihlabathi jikelele ngeendawo ezinobungozi.
- ATEX: Ifuneka kwiimarike zaseYurophu.
- UL: Isetyenziswa ngokuqhelekileyo eMntla Melika.
Ingcebiso kubathengi: Ngalo lonke ixesha jonga amanqaku esiqinisekiso phambi kokuthenga izibane ezingagqabhukiyo ukuze uqinisekise ukuba ziyahlangabezana neemfuno zommandla wakho.
IiMfuno eziKhethekileyo zeZibane zoKuqhushumba eLwandle-Ubungqina
Imekobume yaselwandle inyanzelisa iimfuno ezizodwa kwizibane ezikhusela uqhushumbo ngenxa yeemeko zazo ezinzima:
- Ukuxhathisa ukonakala:
Isitshizi setyuwa kunye nokufuma kunokonakalisa imathiriyeli eqhelekileyo ngokukhawuleza. Khetha izixhobo ezenziwe ngentsimbi engatyiwa okanye ialluminiyam ukuqinisekisa ubomi obude. - Ukuxhathisa kukothuka:
Iinqanawa zifumana ukungcangcazela rhoqo ngexesha lokusebenza. Izibane ezingenakuqhambuka ziyilwe kunye nezakhiwo ezichasayo ukugcina uzinzo kunye nokukhusela umonakalo. - Ukusebenza kwamandla:
Itekhnoloji ye-LED iya ithandwa kakhulu kwizicelo zaselwandle ngenxa yokusebenza kwayo okuphezulu, ixesha elide lokuphila, kunye neendleko zokuyilungisa ezicuthiweyo.
Into yokuphonononga: Umkhumbi wokuloba osebenza kumanzi afumileyo etropikhi ufumanise ukuba ukutshintshela kwizibane ezinogqabhuko-zibane ezisekelwe kwi-LED ezinemilinganiselo ye-IP67 zicuthe ukusetyenziswa kwamandla nge-30% ngelixa ziphucula ukuthembeka kwiimeko ezinzima.
