Anthu ambiri akamva mawu akuti 'valavu yachitsulo chosapanga dzimbiri' amajambula chinthu chonyezimira komanso chosawonongeka. Ndilo lingaliro lolakwika loyamba. Chowonadi ndi chovuta kwambiri komanso chosangalatsa kwambiri. Sizinthu zokhazo; ndi za kamangidwe ka tirigu kuchokera kuponyera, ndi kulolerana Machining, yeniyeni kalasi kukana kapena malo enaake a mankhwala, ndi kusalephereka malonda-offs. Ndawonapo mapulojekiti ochuluka kwambiri a 304 kapena 316 valve pachilichonse, kungoyang'anizana ndi kulephera msanga m'munda. Pulichi ndi facade chabe. Nkhani yeniyeni ili muzitsulo ndi ntchito yopanga kumbuyo kwake.
Maziko: Zimayamba ndi Kuponya
Simungathe kupanga valavu yodalirika kuchokera ku kuponyera koyipa. Apa ndipamene zaka zambiri, monga zomwe mumapeza pakugwira ntchito kwanthawi yayitali, ndizofunikira. Ndikukumbukira ndikuwunika gulu la valavu yachitsulo chosapanga dzimbiri matupi a mzere wa chakudya chamankhwala. Papepala, anali 316L. Zowoneka, zinali zabwino. Koma pakuyesedwa kolowera kwa utoto, netiweki ya micro-shrinkage porosity idawonekera, mugawo lofunikira lakhoma. Gululo lidapangidwira malo okhala ndi chloride. Kukanakhala kutayikira kudikirira kuchitika. Kuwongolera kwamachitidwe a foundry-momwe amawongolera kutentha, nkhungu, ndi kuzizira - ndizo zonse. Kampani yomwe yakhala ikusewera kwazaka zopitilira 30, monga Qingdao Qiangsenyuan Technology (QSY), ikadathetsa izi pobwereza kubwerezabwereza. Kuyang'ana kwawo pa nkhungu ya zipolopolo ndi kuponyera ndalama ndizofunikira kwa ma valve; njira zimenezi kupereka bwino dimensional kulondola ndi pamwamba mapeto kwa ndime zovuta zamkati poyerekeza ndi ena njira mchenga kuponyera, kutanthauza zochepa kukonza Machining ndi zogwirizana kwambiri chomaliza mankhwala.
Kusankha kwazinthu pagawo loponyera ndi chisankho china chosasinthika. Chitsulo chosapanga dzimbiri ndi gulu lalikulu. Pa mzere wamadzi wokhazikika, CF8 (yofanana ndi 304) ikhoza kukhala yokwanira. Koma pakugwiritsa ntchito m'mphepete mwa nyanja ndi kupopera mchere nthawi zonse, mukuyang'ana giredi yapamwamba kwambiri, ngati F55. Vuto loponya limalumpha mokulira. Kuphatikizika kwa alloy kuyenera kusungidwa mkati mwa zenera lolimba kwambiri, ndipo kutenthetsa pambuyo poponya kuti mukwaniritse bwino ferrite-austenite ndikofunikira. Ndawonapo ma valve akusweka panthawi ya makina chifukwa kutentha kwa kutentha kunazimitsidwa ndi madigiri angapo. Ndi chikumbutso kuti ntchito ya valve imatsekedwa nthawi yayitali isanafike pa benchi ya msonkhano.
Apa ndipamene ukadaulo wa ma aloyi apadera, monga opangidwa ndi nickel, umakhala wofunikira. Tinali ndi pulojekiti yokhudzana ndi nthunzi yotentha ya asidi. Standard 316L ikanatafunidwa. Yankho lake linali valavu yopangidwa kuchokera ku Aloyi 20Cb3. The foundry mphamvu yosamalira exotics wotere si sidebar; ndi luso lofunikira pothana ndi ntchito zowononga. Sikuti kukhala ndi aloyi pa mndandanda; ndikudziwa kuponya popanda kutulutsa misozi yotentha kapena tsankho.
Machining: Kumene Kulondola Kumakumana Ndi Zothandiza
Kujambula ndi chosema chaukali. Makinawa amabweretsa moyo. Ndipo ichi ndi chowonadi chothandiza: njira yopangira makina a valavu yachitsulo chosapanga dzimbiri thupi ndi losiyana ndi la chipika chachitsulo chofewa. Zosapanga dzimbiri-zolimba. Ngati chida chanu sichili chakuthwa, kuthamanga kwanu ndi zakudya sizili bwino, mumawotcha pamwamba m'malo mozidula, ndikupanga chosanjikiza cholimba chomwe chingayambitse ming'alu pansi pa kukakamizidwa kwa cyclic. Ndinaphunzira izi movutirapo kale, ndikupanga ma wedges a zipata omwe amawombera ndikugwira pamayesero oyambirira. Kumaliza kwake kunali kokongola, koma kopanda ntchito.
Malo opangira makina a CNC amapereka kubwereza, koma chidziwitso cha wopanga mapulogalamu ndi chomwe chimapangitsa kukhala chodalirika. Kayendedwe kachitidwe kachitidwe kakufunika. Kodi mumabowola thumba la mpando musanabowole kapena mutatha kubowola tsinde? Kodi mumakonza bwanji thupi lowoneka modabwitsa kuti mumalize kumaliza kumaso kwa flange popanda kupangitsa kupsinjika? Kwa mavavu ovuta a madoko angapo, ichi chimakhala chithunzi cha 3D. Sitolo yokhala ndi chidziwitso chakuya cha CNC, chomwe mutha kuwunika kuchokera pamagawo awo patsamba ngati https://www.tsingtaocnc.com, imakhala ndi machitidwe awa okhazikika. Iwo sali chabe kudula zitsulo; amayang'anira kupsinjika kotsalira ndikusunga zolozera za data pamaseti angapo.
Ndiye pali mapeto. A 32 Ra microfinish pampando wa valavu ya mpira akhoza kutchulidwa. Kukwaniritsa izi pamtunda wosapanga dzimbiri, mosasinthasintha, kudutsa mazana a mayunitsi, ndi luso. Nthawi zambiri imaphatikizapo kuphatikiza kwa CNC kutembenuka ndiyeno odzipereka lapping kapena akupera ntchito. Ndayendera zokambirana komwe gawo lomalizali likuchitidwabe ndi akatswiri odziwa ntchito omwe 'amamva' kumaliza. Ndi kuphatikiza kwamakono kwa CNC ndi luso lamakono lomwe nthawi zambiri limapereka malo osindikizira odalirika kwambiri.
The Assembly & Testing Pitfalls
Apa ndi pamene zigawo zabwino zimatha kukhala valavu yoyipa. Msonkhano umawoneka wowongoka: ikani thupi, chepetsa (tsinde, mpira, mpando), ndikusindikiza pamodzi. Koma mdierekezi ali mwatsatanetsatane. Cholakwika chofala ndikugwedeza kwambiri wotsatira wa gland pa valve yokwera. Izi zimasokoneza kulongedza, kumapangitsa kukangana kwakukulu pa tsinde, ndipo kumayambitsa kuvala msanga komanso valavu yovuta kugwira ntchito. Zolemba za torque zilipo pazifukwa, komabe nthawi zambiri amanyalanyazidwa pamalo ogulitsira mwachangu kuti amalize kuyitanitsa.
Kuyesa ndi gawo lina lomwe lili ndi kusiyana kwakukulu. Kuyesa kwa chipolopolo cha hydrostatic ndikokhazikika, zedi. Koma kodi mayeserowa akuphatikizapo kuyesa kwapampando wa sitiroko kwa ma valve otseka? Kwa utumiki wovuta, uyenera. Ndikukumbukira nkhani yomwe gulu la chitsulo chosapanga dzimbiri ma valve a globe adapambana mayeso a chipolopolo koma adawukhira momvetsa chisoni pakuyesa mpando. Choyambitsa chake chinayambika ku kusokoneza pang'ono panthawi yomaliza ya diski ndi mpando-vuto lomwe kuyesa kwa mpando kokha kungasonyeze. Wopanga mwamphamvu adzakhala ndi njira yoyesera yokhazikika, osati kukakamiza kumodzi kokha.
Ndipo tiyeni tikambirane za ukhondo. Pantchito ya okosijeni kapena kugwiritsa ntchito mankhwala, izi ndizofunikira kwambiri. Mafuta, fumbi, kapena zitsulo zilizonse zomwe zimasiyidwa ndi makina zitha kukhala zoopsa pamoto kapena gwero loipitsidwa. Malo ochitira msonkhanowo ayenera kuyendetsedwa bwino, ndipo njira zoyeretsera ndi kunyamula zikwama ziyenera kukhala zokhwima. Ndi mtengo womwe nthawi zambiri umanyalanyazidwa womwe umalekanitsa valavu yazinthu kuchokera ku yodalirika kwambiri.
Zolephera Zenizeni Zapadziko Lonse ndi Maphunziro
Palibe chomwe chimaphunzitsa ngati kulephera. Nthawi ina tinaikapo ma valve 304 a mpira wosapanga dzimbiri pamzere wa madzi ozizira a chomera cha m'mphepete mwa nyanja (madzi a brackish). M'miyezi 18, tinali kuthana ndi kutayikira kozungulira tsinde ndi zisindikizo za thupi. Chomwe chinachititsa kuti pakhale dzimbiri la ming'alu. Ngakhale kuti 304 imakhala ndi kukana kwa dzimbiri, malo osasunthika apakati pa tsinde ndi kulongedza, ndipo pansi pa ma gaskets, adapanga ma cell a oxygen. Ma chloride adakhazikika, ndipo kuphulika kunayamba. Tidasinthira ku mavavu 316 okhala ndi kapangidwe kabwino ka gasket ndikulongosola kayendetsedwe kake pafupipafupi. Phunziro: Kusankhidwa kwa zinthu kuyenera kuwerengera malo omwe ali, kuphatikizapo malo omwe ali osasunthika ndi ming'alu.
Phunziro lina linabwera pa njinga yamoto yotentha. Mavavu a 316L oponyedwa pamzere wobwerera wa nthunzi adayamba kusweka pa kulumikizana ndi boneti ya thupi patatha chaka chantchito. Kafukufukuyu anasonyeza kutopa kwa kutentha. Kuponyera, ngakhale kumveka, kunali ndi mpweya wochuluka wa kalasi (pa malire apamwamba). Izi, kuphatikiza ndi kutentha kobwerezabwereza ndi kuzizira, zimalimbikitsa mpweya wa carbide pamalire a tirigu, kuchepetsa ductility. Kukonzekera kunali kutulutsa ma valve okhala ndi satifiketi ya L-grade (low carbon) komanso mbiri yakale yosamalira kutentha. Idatsindika kuti satifiketi ya mphero ndi poyambira, osati chitsimikizo.
Kupeza ndi Kufunika kwa Wothandizira Wapadera
Izi zimandibweretsa ku sourcing. Kupeza wogulitsa yemwe amawongolera njira kuchokera kusungunuka kupita ku makina ogulitsa ndi mwayi waukulu. Pakabuka vuto, simunatsekerezedwe pakati pa maziko ndi malo ogulitsira makinawo akudzudzulana. Wopanga wophatikizika, kapena yemwe ali ndi zigwirizano zozikika mozama ngati kampani yomwe yasintha zaka 30 kuchokera pakupanga makina olondola, atha kutsata zomwe zidayambitsa. Kodi chinali kuphatikizidwa kwa slag mu kuponya? Kugwedezeka kwa zida panthawi yachisanu ya makina opangira? Iwo akhoza kuzipeza.
Kuyang'ana kuthekera kwa ogulitsa, monga zomwe zalongosoledwa ku Qingdao Qiangsenyuan Technology Co., Ltd., ikutiuza nkhani. Pazaka makumi atatu akuponya ndi kupanga, akugwira ntchito ndi sipekitiramu kuchokera ku chitsulo chonyezimira kupita ku nickel alloys — mbiri ikuwonetsa kuti adakumanapo ndikuthetsa ma gremlin ambiri enieni. Webusaiti yawo, https://www.tsingtaocnc.com, ikuwonetsa kuyang'ana kwambiri pakupanga ma valve. Pamene mukufufuza a valavu yachitsulo chosapanga dzimbiri pakugwiritsa ntchito movutikira, cholowacho ndi chofunikira monga chojambula chomaliza. Ndiko kusiyana pakati pa kugula gawo ndi kugula gawo ndi kuya kwa chidziwitso chopangidwa kumbuyo kwake.
Pamapeto pake, valavu yodalirika yachitsulo chosapanga dzimbiri ndikugwirizanitsa kwazitsulo zolondola, kuponyedwa kolondola, kukonza makina, ndi kusonkhanitsa mosamala. Nthawi zambiri si njira yotsika mtengo, chifukwa masitepe onsewa amawononga ndalama zambiri. Koma m'mafakitale, mtengo wolephera-nthawi yocheperako, kumasulidwa kwa chilengedwe, zoopsa zachitetezo-zimakhala zochepa kusiyana kwamitengo. Cholinga sikugula vavu; ndikugula chipangizo chosindikizidwa, chodutsa malire kuti chizigwira ntchito modziwikiratu pa moyo wake wonse. Ndipo izi zimafuna kuyang'ana kupyola malo opukutidwa.
