Anthu ambiri akamva mawu akuti 'pampu yachitsulo chosapanga dzimbiri' amayerekezera chinthu chonyezimira komanso chosawonongeka. Ndilo lingaliro lolakwika loyamba. Zoona zake n'zakuti, kalasi ndi yofunika kwambiri kuposa chizindikiro. 304 ikhoza kukhala yabwino potumiza madzi, koma ikani m'njira yocheperako yamankhwala kapena, choyipa, malo amchere, ndipo mudzawona kulephera mwachangu kuposa momwe mungaganizire. Ndawonapo ma projekiti ambiri oti 'zopanda banga' ngati zophatikizika, kungothana ndi dzimbiri msanga komanso zokwera mtengo. Sizinthu zokhazo; ndi za zinthu zoyenera pa ntchitoyo, ndi momwe zimapangidwira.
Maziko Oyikira: Kumene Kudalirika Kumapangidwa
Apa ndi pamene nkhani yeniyeni imayambira. Kukhalitsa kwa mpope sikungopangidwa; zaponyedwa. Nyumba, choyambitsa, volute - zigawo zofunika izi zimayambira moyo wawo mu nkhungu. Pazaka makumi atatu pankhaniyi, ndaphunzira kuti njira yoyambira ndi ngwazi yosadziwika. Gawo losasunthika bwino, ngakhale mu 316L, lidzakhala ndi ma inclusions, malo ofooka, kapena micro-porosity yomwe imakhala malo olephera pansi pa kukakamizidwa kapena kuwononga. Simungathe kupanga makina abwino kukhala oponya moyipa.
Ichi ndichifukwa chake kufufuza ndi pompa zitsulo zosapanga dzimbiri chigawo chopanga zinthu ndizofunikira. Ndagwira ntchito ndi ogulitsa omwe amadula njira zosungunula kapena kutentha kwapambuyo, ndipo zotsatira zake zimakhala zofanana nthawi zonse: kusagwirizana kwa ntchito komanso moyo wosayembekezereka. Kampani ngati Malingaliro a kampani Qingdao Qiangsenyuan Technology Co., Ltd., ndi cholinga chawo kwa nthawi yaitali chipolopolo nkhungu kuponyera ndi kuponya ndalama, amamvetsa izi. Ulamuliro wawo wa zaka 30 si chiwerengero chabe; imalankhula ndi kuwongolera koyengedwa pazitsulo ndi kupanga nkhungu zomwe zimatanthawuza mwachindunji kukhulupirika kwadongosolo mu gawo lomaliza la mpope. Kupanga zipolopolo, mwachitsanzo, kumapereka kutsirizika kwabwinoko komanso kulondola kwambiri kuposa kuponyera mchenga kwachikhalidwe, zomwe zikutanthauza kuti kupsinjika kochepa komanso mawonekedwe oyenda bwino mkati mwa chipinda chopopera.
Ndikukumbukira pulojekiti yomwe tinali kukonzanso mapampu kuti tigwiritse ntchito madzi ozizira a m'mphepete mwa nyanja. Zomanga zachitsulo zoyambirira zinali kugwa. Tinasinthira ku a chitsulo chosapanga dzimbiri mpope, koma gulu loyamba loponyedwa kuchokera kwa wogulitsa watsopano linalephera mowoneka bwino-kufufuza kwa ma deoxidizer osayenera. Tinayenera kuchotsa gawo lonse. Linali phunziro pakuwunika osati satifiketi yazinthu zokha, komanso protocol yamtundu wonse wa foundry. Kusasinthika kochokera kuzinthu zakale sikungakambirane.
Kulondola kwa Machining: Zokwanira Zomwe Zimatanthawuza Kuchita
Ngakhale kuponyedwa kwangwiro kumangokhala chosema chaukali. Kulondola kumachokera ku makina. Kulekerera kwa mawondo a shaft ya pampu, kumapeto kwa chipinda chosindikizira, mphamvu ya mphamvu ya choyikapo nyali - izi ndi zomwe zimalekanitsa kavalo wabata, wogwira ntchitoyo ndi mphamvu yonjenjemera, yomwe ikutha. CNC makina ndi muyezo pazifukwa, koma si onse CNC masitolo ali ofanana pampu zigawo.
Vuto ndi chitsulo chosapanga dzimbiri ndi chizoloŵezi chake chogwira ntchito. Ngati makina anu akuzimitsidwa - kuchuluka kwa chakudya, kuthamanga, kuziziritsa, mutha kuwononga zinthu zomwe zili pamwamba, kupanga ma fractures kapena khungu lolimba lomwe limakonda kusweka. Ndakhala ndi ma impellers abwera kuchokera ku makina omwe amawoneka angwiro koma olephera kuyesa bwino chifukwa njira ya chida idapangitsa kupsinjika kotsalira. Ndi chinthu chobisika chomwe chimangowonekera pogwira ntchito.
Apa ndipamene luso lophatikizika limafunikira. Wothandizirana yemwe amayang'anira zonse zoponya ndi CNC makina m'nyumba, monga momwe QSY imatchulira muzochita zawo, ili ndi mwayi waukulu. Okonza makinawo amamvetsetsa kapangidwe kambewu ndi kachitidwe kawo omwe akugwira nawo ntchito. Iwo akhoza kusintha ndondomeko kutengera kutentha kwambiri zambiri chitsulo chosapanga dzimbiri kapena aloyi wapadera. Kupitilira uku kumachepetsa zosinthika ndipo, mwachidziwitso changa, kumabweretsa gawo lodalirika lomaliza la pompa zitsulo zosapanga dzimbiri wosonkhanitsa.
Zinthu Zakuthupi: Sizingokhala Zopanda banga
Tiyeni tinene mwachindunji. 304, 316, 316L, Duplex, Super Duplex, ngakhale ma aloyi opangidwa ndi nickel ngati Alloy 20 kapena Hastelloy C - onse amagwera pansi pa ambulera ya 'stainless' ya mapampu. Kusankha ndi chilichonse. 316L, yokhala ndi molybdenum, ndiyomwe imakhala yosasinthika pazamankhwala ambiri, koma kufooka kwake ndi ma chloride. Ndipamene zitsulo za Duplex, zosakanikirana ndi austenitic-ferritic, zimabwera ndi kukana kwabwinoko kwa kupsinjika kwa dzimbiri.
Ndidagwira ntchito yopanga biodiesel pomwe mtsinjewu unali ndi mafuta acids ndi methanol. Poyamba tinkaganiza za 316L. Zinatenga chaka chimodzi, kenako tidayamba kuwona nkhope za gasket. Zachidziwikire, kutsata ma chloride kuchokera ku kuipitsidwa kwa feedstock ndiye adayambitsa. Tinayenera kukweza mbali zonyowa kuti zikhale a wapamwamba duplex chitsulo chosapanga dzimbiri. Zinali ndalama zobweza ndalama zomwe zikanapewedwa ndi kusanthula koyambirira kwamadzimadzi komanso kusankha zinthu. Pampu ndi maziko ake amatha kukhala 304, koma gawo lililonse lonyowa limafunikira kukweza.
Ichi ndichifukwa chake mndandanda wazinthu za ogulitsa ukunena. Pamene kampani imatchula zochitika ndi ma aloyi apadera monga ma aloyi opangidwa ndi cobalt kapena faifi tambala, zimasonyeza kuti ali ndi zida zogwirira ntchito zovuta, kutentha kwambiri, kuwononga kwambiri, kapena kupukuta matope. Awa si mayankho apashelufu; amafunikira chidziwitso chapadera pakupanga ndi kupanga makina, zomwe zimapangitsa kuti zikhale zolimba pompa zitsulo zosapanga dzimbiri chifukwa cha utumiki kwambiri.
Assembly & Real-World Ghosts
Mutha kukhala ndi zida zoponyedwa bwino komanso zopangidwa ndi makina, ndikusonkhanitsanso pampu yoyipa. Kulumikizana pakati pa tsinde ndi manja, kulumikiza nkhope za makina osindikizira, kugwedezeka koyenera kwa zomangira—apa ndipamene nthawi zambiri kulephera kwa ntchito kumayambira. Ndawonapo chopondera chokongola kwambiri chawonongeka chifukwa ogwira ntchito pamsonkhanowo adagwiritsa ntchito nyundo kuti akhazikitse patsinde, zomwe zidadabwitsa kuyambira tsiku loyamba.
Mzukwa wina ndi cavitation. Anthu amadzudzula mpope, koma nthawi zambiri ndi vuto la dongosolo. Komabe, zinthu ndi kapangidwe ka mpope zingakhudze kuwonongeka. A cavitating mpope adzadya mwa zinthu zilizonse, koma otsika kalasi chitsulo chosapanga dzimbiri kapena amene ali ndi zolakwika zoponya adzakokoloka ndi kugwa mofulumira kwambiri. Kuponyedwa kwapamwamba kwambiri ndi kalasi yoyenera kungakugulireni nthawi yoti mufufuze ndi kukonza vuto la dongosolo musanayambe kulephera kwathunthu.
Ndizovuta izi zapakati - zomwe zili pakati pa chigawocho ndi kuyika komaliza - zomwe zimalamulira moyo wa akatswiri opopera. Ubwino wa zigawo zoyambira kuchokera ku foundry ndi shopu yamakina zimayika denga pazomwe zingatheke m'munda. Ngati mbalizo zili bwino, mukulimbana ndi vuto la dongosolo, osati zolakwika za zida.
Kuyang'ana Mmbuyo Kuti Tipite Patsogolo
Ndiye, chotengera ndi chiyani? Kufotokozera a pompa zitsulo zosapanga dzimbiri si ntchito ya bokosi. Ndilo zisankho zambiri: aloyi yolondola yamadzimadzi ndi chilengedwe, njira yoponyera yomwe imatha kutulutsa phokoso, mawonekedwe osakanikirana, makina olondola omwe amalemekeza katundu wa zinthuzo, ndipo potsiriza, kusonkhana koyenera ndi kuphatikiza dongosolo.
Ndikawunika ogulitsa, tsopano ndimayang'ana kupyola kabuku ka mpope kupita kumagulu awo opanga. Mbiri ngati Zithunzi za QSY-Zaka 30 popanga ndi kupanga makina osiyanasiyana kuchokera kuchitsulo kupita ma aloyi apadera-zimasonyeza kuzama kwazitsulo ndi chidziwitso cha ndondomeko zomwe zimasefera kudalirika kwa chinthu chomaliza. Iwo sali chabe ogulitsa; iwo ndi gwero la zomangira zofunika kwambiri.
Nthawi ina mukadzagwira nawo ntchito yopopa, fufuzani zomwe zidachokera. Funsani za njira kuponyera, kutentha mankhwala, Machining gwero. Ndiko komwe nkhondo yeniyeni ya moyo wautali imapambana kapena kutayika, kale mpope isanawone dontho lake loyamba lamadzimadzi. Malo owala ndi mathero a nkhani yayitali kwambiri, yatsatanetsatane.
