Chingwe chilichonse cholowera m'malo osayaka moto ndi njira yoyaka moto. IEC 60079-1 imatchula kulolerana kwapang'onopang'ono kwa tizingwe tating'onoting'ono ndi zolumikizira zolumikizira. Kugwiritsa ntchito zingwe zopangira zingwe zamafakitale popanda chiphaso cha Ex d ndikulephera kuyesa kokha. Tchulani ma gland ovomerezeka kuyambira pachiyambi ndikutsimikizira kuti miyeso ya ulusi wa gland ikugwirizana ndi kukula kwa abwana. Thread mismatch ndi cholakwika chodziwika bwino chophatikizika chomwe chimangowoneka panthawi yowunikira ziphaso.
Ngati gulu lanu la mainjiniya likuwunika ngati batire ya paketi ikukwaniritsa zofunikira za batire yowona zone 1 kapena kuphulika kokulirapo-zofunika zotsimikizira za misika inayake ya migodi, gulu lathu latsogolera 40+ mapulojekiti panjira zonse za IECEx, ATEX, MA, ndi MSHA. Kuti mudziwe matimu ogula zinthu amene akuwunika -ma batire ovoteledwa pazida za migodi, onani wathumigodi locomotive ndi migodi magalimoto batire njirakwa ma specifications ndi certification coverage.
FAQ
Q: Kodi pali kusiyana kotani pakati pa ATEX ndi IECEx satifiketi yamabatire amigodi?
A: ATEX ndiyovomerezeka kumsika wa EU pansi pa Directive 2014/34/EU ndipo imafuna kuwunika kwa Body Notified. IECEx imapereka kuzindikirika kwapadziko lonse lapansi kumayiko onse 30+ koma sikuvomerezedwa ku United States (MSHA ikufunika) kapena China (ikufunika MA). Onse amatchulanso miyezo yaukadaulo ya IEC 60079, chifukwa chake zoyeserera zimasamutsidwa pakati pa njira.
Q: Kodi chizindikiro cha Ex pa batire ya migodi chimatanthauza chiyani?
A: Chizindikiro cha Ex chimabisa mtundu wa chitetezo, gulu la gasi, kalasi ya kutentha, ndi chitetezo cha zida. Pogwiritsa ntchito migodi ya Gulu I, zolembera zimasiyana ndi zida zamakampani za Gulu II, kutsimikizira kutsata kwa methane ndi fumbi la malasha m'malo motengera gasi wamba.
Q: Chifukwa chiyani mabatire osaphulika{{0}angagwiritsidwe ntchito m'migodi ya pansi pa nthaka?
Yankho: Migodi ya pansi pa nthaka imatchedwa Gulu I, yomwe imafunika kutetezedwa nthawi imodzi ku mpweya wa methane ndi fumbi la malasha. Kuphulika kwa mafakitale{1}}mabatire odziŵika kuti azitha kuphulika mu Gulu II adilesi imodzi-pamalo a mpweya wokhawokha ndipo alibe chitetezo chapawiri-chotetezedwa chomwe malamulo oteteza migodi amalamula.
Q: Kodi -chitsimikizo cha certification certification chimawononga ndalama zingati pamabatire akumigodi?
A: Mitengo imachokera pa $30,000–$100,000 pa chiphaso chimodzi-cha ATEX chamsika kufika pa $150,000–$500,000 pamapulogalamu-ofanana amsika. Kusintha kwakukulu kwamitengo ndikuti ngati chotengera chothawa moto chidapangidwa kukhala batire kuyambira koyambira kapena kusinthidwanso panthawi yoyeserera.
Q: Kodi chiwopsezo chachikulu cha kulephera kwa certification kwa opanga mabatire a migodi ndi chiyani?
A: Kupanga paketi ya batri popanda kuphatikizira kuphulika-zofunika zotsimikizira kuyambira pagawo loyambirira la uinjiniya. Kubwezeretsanso kutha kwa kutentha, kuchepetsa kupanikizika, ndi vuto la BMS-zomwe zimayankhidwa panthawi ya certification nthawi zambiri zimabweretsa kuchulukira kwa bajeti kwa 4× ndi kuchedwa kwa miyezi 12-18.
Lumikizanani ndi gulu lathu la engineering kuti mukambirane zanumigodi batire zofunika satifiketi.
