I-ATEX vs. Ex d: Izikhokelo zoLawulo zithelekiseka

I-ATEX kunye ne-Ex d zimele imiba eyahlukeneyo yokukhusela ugqabhuko-dubulo, kunye ne-ATEX iyisakhelo solawulo kunye ne-Ex d luhlobo oluthile lobuchule bokukhusela. Makhe sihlolisise nganye ngokweenkcukacha:

Ukuqonda i-ATEX

I-ATEX, ephuma kwisiFrentshi "i-ATmosphères EXplosibles," yiseti yemiyalelo ye-European Union elawula izixhobo kunye neenkqubo zokukhusela ezenzelwe ukusetyenziswa kwiindawo ezinokuqhuma. Umyalelo we-ATEX unamacandelo amabini aphambili:

• I-ATEX 2014/34/EU (eyayifudula iyi-94/9/EC): Lo myalelo usebenza kubavelisi kwaye uchaza iimfuno zezixhobo kunye neenkqubo zokukhusela ezijoliswe ekusetyenzisweni kwiindawo ezinokubakho iziqhushumbisi.
• I-ATEX 1999/92/EC: Lo myalelo ujolise kubaqeshi kwaye uchaza ezona mfuno zisezantsi zokuphucula ukhuseleko kunye nokukhuselwa kwezempilo kwabasebenzi abanokuba semngciphekweni woqhushumbo.

Isatifikethi se-ATEX siqinisekisa ukuba iimveliso ziyahlangabezana neemfuno ezibalulekileyo zempilo nokhuseleko kwaye zinokusetyenziswa ngokukhuselekileyo kwiindawo ezinoqhushumbo kwiManyano yaseYurophu.

Ukuguqula ikhowudi Eks d

I-Ex d, kwelinye icala, ibhekisa kuhlobo oluthile lobuchule bokukhusela izixhobo zombane ezisetyenziswa kwiatmosphere eziqhumayo. U-"Ex" uthetha ukhuseleko logqabhuko-dubulo, ngelixa u-"d" umele "indawo ebiyelweyo engatshiyo." Le ndlela yokukhusela ichazwe kuluhlu lwemigangatho ye-IEC 60079, ezizikhokelo ezivunyiweyo kumazwe ngamazwe kwizixhobo zombane kwiindawo eziqhumayo.

Indawo ebiyelweyo ye-Ex d yenzelwe ukuqulatha ugqabhuko-dubulo lwangaphakathi kwaye ithintele ukuvutha komoya ongqongileyo oqhumayo. Indawo ebiyelweyo, njengaleyo isetyenziswa kwi- i-exd motor, kufuneka yomelele ngokwaneleyo ukuze imelane noxinzelelo logqabhuko-dubulo lwangaphakathi kwaye ipholise naziphi na iigesi ezishushu ezibalekayo ukuya kwiqondo lobushushu elingaphantsi kwendawo yokutshisa kwiatmosfera engqongileyo.

Iindidi zezixhobo: i-ATEX kunye ne-Ex d Classifications

Ngelixa i-ATEX kunye ne-Ex d zisebenza ngeenjongo ezahlukeneyo, zombini zibandakanya ukuhlelwa okunceda ukufumanisa ukufaneleka kwezixhobo kwiindawo ezithile ezinobungozi.

I-ATEX Equipment Categories

I-ATEX yahlula izixhobo zibe ngamacandelo amathathu ngokusekwe kwinqanaba lokhuseleko olufunekayo:

• Udidi 1: Inqanaba eliphezulu kakhulu lokhuseleko, lilungele ukusetyenziswa kwiZone 0 (igesi) okanye uMmandla wama-20 (uthuli)
• Udidi 2: Inqanaba eliphezulu lokhuseleko, lilungele ukusetyenziswa kwiZowuni 1 (igesi) okanye uMmandla wama-21 (uthuli)
• Udidi 3: Inqanaba eliqhelekileyo lokhuseleko, elilungele ukusetyenziswa kwiZone 2 (igesi) okanye uMmandla wama-22 (uthuli)

Ezi ndidi zihambelana nemimandla ethile apho imimoya eqhumayo inokubakho rhoqo, ngamaxesha athile, okanye ngokunqabileyo nangethuba elifutshane.

Ex d Classification

Ex d yenye yeentlobo ezininzi zeendlela zokukhusela ezichazwe kwimigangatho ye-IEC 60079. Ezinye iintlobo zokhuseleko ziquka:

• Ex e: Ukhuseleko olongezelelekileyo
• Ex i: Ukhuseleko lwangaphakathi
• Ex p: Indawo ebiyelwe ngoxinzelelo
• Ex q: Ukuzaliswa komgubo
• Ex o: Ukuntywiliselwa kweoli

Nganye kwezi ntlobo zokhuseleko zifanelekile kwizicelo ezahlukeneyo kunye nokuhlelwa kwendawo enobungozi. Exd iimoto, umzekelo, ziqhele ukusetyenziswa kwiindawo apho kukho umngcipheko werhasi okanye ugqabhuko lomphunga.

Ukukhetha phakathi kwe-ATEX kunye ne-Ex d Protection

Xa ukhetha izixhobo eziza kusetyenziswa kwiatmosphere ezinokuba neziqhushumbisi, kubalulekile ukuqonda ukuba i-ATEX kunye ne-Ex d azidibananga. Enyanisweni, bahlala besebenza ngokubambisana ukuqinisekisa ukhuseleko olubanzi.

Ukuqwalaselwa koKhetho lweZixhobo

Izinto ezininzi kufuneka zithathelwe ingqalelo xa ukhetha phakathi kwezixhobo eziqinisekisiweyo ze-ATEX kunye nokhuseleko lwe-Ex d:

1. Indawo: Qwalasela ukuba ngaba izixhobo ziya kusetyenziswa kwi-European Union, apho ukuthotyelwa kwe-ATEX kunyanzelekile.
2. Iingozi ezithile: Chonga iintlobo zemimoya eqhumayo ekhoyo kwindawo yakho (igesi, umphunga, inkungu, okanye uthuli).
3. Ukuphindaphindwa kokwenzeka kweengozi: Qinisekisa ukuba loluphi ulwahlulo lwezowuni olusebenzayo kwindawo yakho yokusebenza.
4. Ukusebenza kwezixhobo: Qwalasela iimfuno zokusebenza kwesixhobo kunye nendlela iindlela ezahlukeneyo zokukhusela ezinokuchaphazela ngayo ukusebenza.
5. Uluhlu lwamandla ombane: Kwizixhobo zombane, qwalasela iimfuno zombane. Ezinye iinjini ze-Ex d, umzekelo, zinokusebenza kumbane we-380V, 660V, okanye nokuba ngu-660/1140V.

Ukudibanisa i-ATEX kunye ne-Ex d

Kwiimeko ezininzi, izixhobo zinokuqinisekiswa yi-ATEX kwaye zisebenzise ukhuseleko lwe-Ex d. Ngokomzekelo, i Exd motor eyenzelwe ukusetyenziswa kwiplanti yekhemikhali yaseYurophu kuya kufuneka ukuba ihlangabezane neemfuno ze-ATEX kwaye ibandakanye ukhuseleko kwindawo ebiyelweyo engatshiyo.

Le ndibaniselwano iqinisekisa ukuba izixhobo:

• Ithobelana nemigaqo ye-EU ukuze isetyenziswe kwindawo eneziqhushumbisi
• Idibanisa iimpawu zoyilo ezithile ukuqulatha ugqabhuko-dubulo olunokubakho
• Ilungele indawo ethile enobungozi apho iya kusetyenziswa khona

Kufanelekile ukuqaphela ukuba ngelixa i-ATEX ikhethekileyo kwiManyano yaseYurophu, i-Ex d kunye neminye imigangatho ye-IEC yamkelwa kwihlabathi jikelele. Oku kuthetha ukuba izixhobo ze-Ex d zihlala zisetyenziswa kumazwe angengawo e-EU, ngaphandle kokuba ziyahlangabezana neemfuno zolawulo lwasekhaya.

Isicelo kwimizi-mveliso eyahlukeneyo

Ukhetho phakathi kwe-ATEX kunye ne-Ex d (okanye indibaniselwano yazo zombini) ibalulekile kuwo onke amashishini amaninzi apho imimoya eqhumayo inokubakho:

• I-oyile kunye neGesi: Amaqonga e-Offshore kunye nezinto zokucokisa zihlala zifuna izixhobo eziqinisekisiweyo ze-ATEX kunye nokhuseleko lwe-Ex d lweemoto, iimpompo kunye neenkqubo zokulawula.
• Ukusetyenzwa kweMichiza: Izibonelelo zokuvelisa eziphethe izinto ezinokutsha zixhomekeke kwi-ATEX kunye ne-Ex d ukuqinisekisa ukusebenza ngokukhuselekileyo.
• Ukumbiwa kwemigodi: Imigodi yamalahle ephantsi komhlaba, apho irhasi yemethane isoloko ixhalabile, ihlala iqesha iimotor ze-Exd ezinesiqinisekiso se-ATEX.
• I-Pharmaceutical: Iindawo zokuvelisa apho i-powders ecocekileyo okanye i-solvents ikhona ingafuna izixhobo ezihambelana ne-ATEX kunye neendlela ezahlukeneyo zokukhusela, kuquka i-Ex d.
• Ukutya kunye nesiselo: Amaziko alungisa ukutya okuziinkozo okanye olunye uthuli olunokutsha luhlala lufuna oomatshini abaqinisekisiweyo be-ATEX, abanye babo banokubandakanya ukhuseleko lwe-Ex d.

Kwishishini ngalinye kula, iimfuno ezithile ziya kuxhomekeka kubume beengozi ezikhoyo kunye nemeko yolawulo apho isibonelelo sisebenza khona.

isiphelo

Ukuqonda umahluko phakathi kwe-ATEX kunye ne-Ex d kubalulekile kuye nabani na obandakanyekayo ekukhetheni, ekufakeni, okanye ekulondolozeni izixhobo kwindawo enokuthi ibe neziqhushumbisi. Ngelixa i-ATEX ibonelela ngesakhelo solawulo sokuqinisekisa ukhuseleko lwezixhobo kwi-EU, i-Ex d ibonelela ngobuchule obukhethekileyo bokukhusela obunokusetyenziswa kwihlabathi jikelele.
