Kusankha choyenera ATEX centrifugal fan sikuti ndikuyang'ana bokosi-komanso kupewa kuyatsa m'mafakitale odzaza fumbi, kupeŵa kulephera kowopsa m'malo opangira utoto wosungunulira, kapena kuwonetsetsa kuti mpweya ukuyenda mosalekeza pomwe kuchuluka kwa methane kumayandikira malire a kuphulika. Tawonapo mafani akuwonetsa mafani a "ATEX-voted" kuti angozindikira-panthawi yotumiza - kuti malo otchingidwa ndi ma mota sanatsimikizidwe ndi magulu amafuta a Zone 1, kapena kuti choyikapocho sichingathe kupirira utsi wodzaza ndi silika. Ichi ndichifukwa chake kusankha sikuyamba ndi manambala amndandanda, koma ndi mafunso atatu osayankhidwa: Kodi magawo omwe ali owopsa ndi ati? Kodi kutentha kwakukulu kwa ntchito ya airstream ndi kotani? Ndipo ndi zovuta zotani zomwe zimakupiza faniziyo zingapirire— dzimbiri, kuvulala, kukwera njinga yamoto, kapena zonsezi?
Chifukwa Chake Chitsimikizo cha ATEX Imafunikira Zambiri Kuposa Label
An ATEX centrifugal fan ziyenera kukwaniritsa zofunikira ziwiri zofananira: mulingo wachitetezo cha zida (EPL) wofananira ndi zone (mwachitsanzo, Ga kwa Zone 0, Gb ya Zone 1), komanso kuyanjana kwa gulu la gasi (IIC ya hydrogen/acetylene, IIB ya ethylene, IIA ya propane). Koma chizindikiritso chokha sichimatsimikizira kugwira ntchito m'munda. Mu projekiti ina yoyenga, zimakupiza zidadutsa kuyesa kwa ATEX pa 25 ° C mozungulira - koma zidalephera pakuyambika kwa chilimwe pomwe kutentha kwapamadzi kudapitilira T4 (135 ° C) chifukwa chosakwanira kutulutsa kutentha. Kutsatiridwa kwenikweni kumatanthauza kutsimikizira kalasi yotentha * pansi pa ntchito yeniyeni *, osati labu chabe. Zimatanthawuzanso kutsimikizira chigawo chilichonse - chokhala ndi zisindikizo, manja a shaft, ngakhale zomangira - zalembedwa pa satifiketi. Timayang'ana pafupipafupi masatifiketi a mayeso amtundu wa EC motsutsana ndi mayunitsi amthupi tisanatumizidwe. Palibe zongoganizira. Palibe kuchotserapo.
Zosankha Zopanga Zomwe Zimalepheretsa Kulephera - Osati Kungokwaniritsa Miyezo
Fani yotsimikizika imalephera ngati kapangidwe kake kakusemphana ndi chilengedwe chake. Ganizirani zisudzo zotsimikiziridwa m'munda:
- Zinthu zopangira ma impeller ndizofunika kwambiri kuposa kusinthasintha kwamphamvu. Zotulutsa za aluminiyamu zimayaka m'malo afumbi lakuda - ngakhale atavomerezedwa ndi ATEX. Titaniyamu kapena zitsulo zosapanga dzimbiri zimachotsa chiwopsezochi, koma zimafuna kusanja kosunthika kuti mupewe kuvala kokhala ndi kugwedezeka komwe kumachititsa kuti mugwire ntchito 24/7 mosalekeza.
- Kuphatikiza kwa injini si pulagi-ndi-sewero. Galimoto yotsimikizika ya ATEX yoyikidwa panyumba yopanda satifiketi imalepheretsa kutsata kwa msonkhano wonse. Chigawo chonse - kuphatikiza ma drive coupling, alonda, ndi maziko - ayenera kuyesedwa ngati dongosolo limodzi.
- Njira yosindikizira imatanthawuza moyo wautali. Milomo yosindikizira imatulutsa fumbi m'mabere mkati mwa miyezi mu utsi wa simenti. Makina otsuka bwino omwe ali ndi jakisoni wa gasi wolowera amakulitsa moyo wautumiki ndi 3–5× m'malo okhala ndi zinthu zambiri.
Tasinthanso mafani opitilira 120 m'malo opangira magetsi oyaka ndi malasha pomwe mpweya wa desulfurization flue udawononga mwachangu ma casings wamba wazitsulo za carbon. Kusintha kwa mafani apakati-inlet centrifugal okhala ndi ma epoxy-coated casings ndi ma impeller a Hastelloy-C276 adadula nthawi yosakonzekera ndi 78% -popanda kusokoneza kukhulupirika kwa ATEX.
Kusintha Mwamakonda Sizinthu Zapamwamba-Ndi Njira Yokha Yofananira Zowona
Otsatira a ATEX a pashelufu amasamalira zolemba zamabuku. Masamba enieni samatsatira mabuku. Chipinda choyeretsera mankhwala chimafunikira mpweya wosaphulika wokhala ndi phokoso la ≤25 dB(A)—losatheka ndi zonyamulira nsonga zozungulira. Yankho: chotengera chakumbuyo chokhotakhota cha titaniyamu, chiwongolero chomangika chophatikizidwa mu volute, ndikuyendetsa molunjika IE4 mota yochotsa chiwopsezo choyambitsa lamba. Nthawi yobereka: masabata a 11. Wogula wina pamzere wopangira sulfuric acid amafunikira kukana H₂SO₄ nkhungu pa 80 ° C ndikusunga chiphaso cha Zone 1 IIB. Zovala zamtundu wa epoxy zimachotsedwa. Tidagwiritsa ntchito zitsulo zokhala ndi mizere ya fluoropolymer zokhala ndi ma shaft okutidwa ndi ceramic-ndikutsimikizira ma coefficients owonjezera amafuta pamtunda wonsewo.
Mwambo sikutanthauza kuchedwa. Makina athu amkati, kupanga zitsulo zamapepala, ndi mizere yoyendera bwino titha kusintha ma geometry a casing, kusintha ma inlet/outlet flanges, kuphatikizira masensa a kutentha, kapena kuwonjezera madoko a purge — zonse popanda kuchedwa kutsimikiziranso, chifukwa timagwira ntchito m'malire apangidwe omwe adavomerezedwa kale.
Chimene Chimabwera Pambuyo pa Invoice Yatsimikizira Chitetezo—Osati Kungotsatira
Zolemba ndiye njira yanu yoyamba yodzitchinjirizira pakufufuza kapena kufufuza zochitika. Aliyense ATEX centrifugal fan kuchokera ku Zibo Hongcheng Fan Co., Ltd. zimatumiza ndi fayilo yaukadaulo yathunthu: satifiketi yoyeserera yamtundu wa EC, malipoti oyesa (kugwedezeka, phokoso, kukwera kwa kutentha), zitsimikiziro zazinthu, ndi ma torque enieni oyika—osati zolemba zamawu. Timaphatikizanso zilembo za QR zolumikizidwa ndi zojambula zowunikidwanso komanso mindandanda yazigawo zotsalira. Malo a petrochemical ku Oman atafunika kusinthidwa mwachangu chowuzira chowotchera chomwe chalephera, gulu lathu la mainjiniya lidawunikiranso mabawuti awo omwe analipo kale, kupirira kwa ma ductwork, ndi ma voliyumu am'deralo - kenaka adatumiza cholowa m'malo ndi ma VFD omwe adakhazikitsidwa kale komanso kutsimikizira kozungulira. Palibe zongoyerekeza. Palibe kukonzanso m'munda.
Chitetezo sichimakwaniritsidwa pakutumiza. Zimathandizidwa ndi kukonza zodziwikiratu, zida zotsatiridwa, ndi mainjiniya omwe adayimilira mchipinda chanu chowongolera poyambitsa. Ichi ndichifukwa chake chithandizo chathu chimaphatikizanso maphunziro okhudzana ndi kugwiritsa ntchito - osati "momwe mungayatse," koma "momwe mungawonere kuwonongeka koyambilira m'malo okhala ndi chinyezi chambiri ku Zone 2."
