Malo owopsa a mafakitale samakhululukira zigawo zofooka. M'mafakitale opangira mankhwala, ma unit flue gas desulfurization, kapena refineries za m'mphepete mwa nyanja, mafani azitsulo za carbon-steel amalephera m'miyezi ingapo-kuboola, kusweka, kugwidwa ndi mpweya wodzaza ndi chloride kapena mpweya wa acidic. Funso lenileni siliri ngati dzimbiri zidzagunda-ndizo pamene, ndi kuchuluka kwa nthawi yocheperako, mtengo wokonzanso, ndi chiwopsezo chachitetezo zomwe zingabweretse. Ichi ndichifukwa chake mainjiniya a Zibo Hongcheng Fan Co., Ltd. Anamanga zitsulo zosapanga dzimbiri zotsutsana ndi dzimbiri zomwe zinapangidwira kuti zigwirizane ndi zero: 316L nyumba zazitsulo zosapanga dzimbiri, ma shaft, ma impellers, ndi zomangira; seams zonse welded; passivated pamwamba; ndi dynamic balancing certification to ISO 1940 G2.5. Osati ngati chosankha-koma ngati maziko.
Chifukwa Chake Chitsulo Chopanda Stainless Sili "Chabwinoko" - Sichikanjanitsika Pamapulogalamu Ovuta
Tawonapo njira zitatu zolephera zomwe zimachitika nthawi zambiri: choyamba, galvanic corrosion pomwe mafelemu a carbon-steel amalumikizana ndi zotulutsa zosapanga dzimbiri - kupanga ma currents ang'onoang'ono omwe amadya ma weld joints. Chachiwiri, mng'alu dzimbiri mkati mwa flanges zopindidwa ndi condensate ndi sulfure dioxide. Chachitatu, kupsinjika-kudzimbirira kung'ambika muzitsulo za fan pansi pa cyclic matenthedwe katundu ndi kuwonekera kwa H₂S. Mafani opangidwa ndi epoxy-coated amaphimba izi-mpaka atayala tchipisi panthawi yokonza kapena kupalasa njinga, kuyika zitsulo zosaphika pansi. Chotenthetsera chachitsulo chosapanga dzimbiri chimachotsa chomwe chimayambitsa: palibe zokutira kuti ziwonongeke, palibe zitsulo zofananira, palibe misampha yobisika. Ku Zibo Hongcheng, zokonda zilizonse za FBD-Ⅱ zomwe zimaperekedwa kuti azithandizira gasi wa malasha zimagwiritsa ntchito ma 316L ducting ndi ma peller osachepera 2.5 mm makulidwe a khoma - osati kungolimbana ndi nkhungu ya asidi, koma kuti athe kupirira tinthu ting'onoting'ono popanda kupatulira kutsika kwapangidwe.
Zochitika Zenizeni Zapadziko Lonse Zimafuna Kupanga Chisankho Chilichonse Chopanga
Ena anganene kuti chitsulo chosapanga dzimbiri ndi chochuluka chifukwa cha chinyezi chochepa. Koma deta yam'munda imanena nkhani ina. Pafakitale yamankhwala ya Shandong yomwe imagwira ntchito mosalekeza 24/7, chotenthetsera cha centrifugal chokutidwa chinatenga miyezi 14 kusanachitike kugwidwa koopsa kwa chloride kupita kumafuta. M'malo mwake zitsulo zosapanga dzimbiri zothana ndi dzimbiri - mpweya womwewo (28,000 m³ / h), kuthamanga komweko (3,200 Pa), ma mota omwewo (55 kW) - agwira ntchito kwa miyezi 47 ndikuzimitsa kosakonzekera. Chifukwa chiyani? Chifukwa Zibo Hongcheng samangosintha zinthu. Amakonzansonso: kukulitsa nyumba zokhala ndi zosindikizira za milomo iwiri zovotera IP68; osalumikizana ndi labyrinth zisindikizo pazowonjezera shaft; ndi mbiri ya tsamba la impeller zokongoletsedwa ndi liwiro lotsika-kuchepetsa kukokoloka ndikusunga bwino. Chowuzira chosapanga dzimbiri cha 9-19, chomwe chimagwiritsidwa ntchito kwambiri ngati mafani a boilers oyambira muzomera zowotchedwa, chimapereka mphamvu 84.3% pachimake pa 1,450 rpm - osati ngakhale kukana dzimbiri, koma chifukwa cha kuphatikizika kwamatenthedwe ndi kapangidwe ka makina.
Kusintha Mwamakonda Amene Amagwira Ntchito—Osati Kungofuna Kutsatsa
"Kusintha mwamakonda" kumatanthauza pang'ono pokhapokha ngati itatumizidwa pa nthawi yake, ikukumana ndi zofunikira, ndikupulumuka kutumidwa. Ku Zibo Hongcheng, kusintha makonda kumayamba ndi uinjiniya wa ntchito - osati masamba ogulitsa. Pamene malo osungunula titaniyamu amafunikira mafani oletsa kuphulika osamva mpweya wamchere wosungunuka pa 450 ° C, gulu lawo silinasinthidwe ndi zomwe zidapangidwa. Adawunikanso malipoti enieni opangidwa ndi gasi, adajambula mapu otenthetsera m'nyumba zonse za fan, adasankha Inconel 625 kuti alowemo, adawonjezera zitsulo zokhala ndi jekete lamadzi, ndikutsimikizira momwe amagwirira ntchito m'nyumba yawo ya 1,200 kW - kuyeza kugwedezeka, kukwera kwa kutentha, ndi kuwola kwamphamvu kwa maola 72 pansi pa katundu woyerekeza. Palibe nambala yamakatalogu yapashelufu. Palibe "kutengera kuwunika kwaukadaulo." Zongolembedwa, zobwerezabwereza, zotsimikiziridwa ndimunda. Chitsulo chawo chosapanga dzimbiri chotsutsana ndi dzimbiri chimaphatikizapo mitundu 17 yokhala ndi ziphaso za ATEX, IECEx, kapena CCC-Mine - ndipo gawo lililonse limatumiza ndi malipoti oyeserera azinthu (MTRs), ziphaso zoyendera bwino, komanso ma curve odzaza ndi katundu wolembedwa ndi mainjiniya olembetsedwa.
Kudalirika Mungathe Kutsimikizira-Musanayike
Chikhulupiriro chimabwera chifukwa chochita zinthu poyera, osati m'mabuku. Chitsulo chilichonse chosapanga dzimbiri chotsutsana ndi dzimbiri kuchokera ku Zibo Hongcheng chimadutsa malo anayi ovomerezeka: kutsimikizira zakuthupi kudzera pamanja XRF spectrometer (kutsimikizira Mo ≥ 2.5%, Cr ≥ 16.5%, Ni ≥ 10.5%); kuyang'ana mozama pogwiritsa ntchito zida zovomerezeka za CMM; kuyezetsa kogwira ntchito pa 110% kuvotera liwiro kwa mphindi 30 ndi kuyang'anira nthawi yeniyeni kugwedezeka (<0.71 mm / s RMS pa liwiro la ntchito); ndikuwunika komaliza kutayikira ndi helium mass spectrometry pamakona onse owotcherera. Palibe chomwe chimatumiza popanda cholembera cha digito chokhala ndi QR cholumikizira makanema oyesera, masikanidwe a MTR, ndi zipika zamasankho. Umu ndi momwe mumapewa kulakwitsa kwa $ 120,000: kuyika zokonda "zopanda banga" kuti mupeze 304-osati 316L - ndipo zimalephera m'miyezi isanu ndi umodzi pafupi ndi scrubber ya chlorine.
Kuyenda kwa mpweya m'mafakitale sikukhudza kusuntha mpweya-komanso kupititsa patsogolo ntchito, kuteteza ogwira ntchito, komanso kupewa kulephera kwamphamvu. Chitsulo chosapanga dzimbiri chotsutsana ndi dzimbiri sichinthu chamtengo wapatali. Ndilo mzere woyamba wa chitetezo ku chiopsezo cha systemic. Zibo Hongcheng Fan Co., Ltd. amawamanga kuti asakwaniritse miyezo yocheperako - koma kuti azikhala ndi moyo kuposa zida zomwe amagwiritsa ntchito. Chifukwa m'malo ovuta, kukhazikika sikusankha. Ndizomwe zimafunikira.
