Zvikamu zvesimbi zvakakandwa zvinogadzirisa matambudziko epasirese-anodonhedza hydraulic manifolds, yakatsemuka pombi dzimba pasi pe300-bar pressure, mawinch shafts anotadza mushure memwedzi gumi nemisere munzvimbo dzekupfapfaidza munyu. Uku hakusi kukundikana kwedzidziso. Isu takayera ma microcracks muAMS 5387 cobalt alloy nozzles akadzoka kubva kumahombekombe ekuchera. Isu takagadzirisa kutenderera kwekupisa mushure mekuona dimensional kudonha muT800-based piston pombi silinda dzimba panguva yekupisa bhasikoro bvunzo. Zvikamu zvesimbi zvinobudirira chete kana simbi, geometry, uye kushushikana kwekushandisa kunoenderana-kwete kana zvirevo zvichitaridzika zvakanaka pabepa.
Sei "Kungokanda" kusina kukwana kune Mishoni-Yakakosha masisitimu
Mainjiniya mazhinji anoziva kukanda jecha kunobata zvimiro zvakakura. Investment casting inopa kushivirira kwakanyanya. Asi vashoma vanoziva kuti 0.05 mm mold misalignment zviri nyore sei kana 2°C kutsauka mukudurura tembiricha kunokonzeresa porosity mumiviri yevharuvhu inomanikidza. Isu takaona matatu akafanana simbi anokandwa-patani imwe chete, imwechete yevatani batch-yakundikana kuyedza kuvuza nekuti imwe yakatonhodzwa maminetsi gumi nemaviri nekukurumidza pane shakeout pasi. Ndicho chikonzero kunyatsojeka kusiri kwezviyero zvekupedzisira chete. Iri pamusoro pekudzora kusimba magradients, chimiro chezviyo kufanana, uye kusara kwekushushikana kwekugovera * pamberi * machining atanga.
Kudzora ikoko kunotanga nekutarisisa kwezvinhu. Yese cobalt-nickel alloy ingot yatinogadzira inotakura mishumo yeguyo yakazara: kusimba kwesimba pa650 ° C, kureba mushure mekutyoka, intergranular corrosion resistance paASTM G28A. Hapana batch rinopinda mukukandira pasina kuonesa kabhoni yemukati inogara mukati me ± 0.02% yeAMS 5387 spec. Sei? Nekuti 0.03% yakawandisa kabhoni inoshandura cobalt alloy 6 kuita brittle, crack-prone matrix pasi pe cyclic kurodha.
Yedu ISO-inoenderana nzvimbo inomhanya yakafanana kukanda uye CNC mitsetse-kwete semadhipatimendi akaparadzana, asi sematanho akawiriraniswa. Kukandwa kwesimbi kunosvika kuchisero chekugadzira chine hutsinye hwayo hwekukandwa hwakamepurwa nelaser profilometry. Iyo CNC chirongwa chinogadzirisa mareti ekudya otomatiki munzvimbo umo micro-shrinkage yakagadzira yakaomeswa spikes. Kubatanidzwa uku kunodzivirira kutaurirana kwezvishandiso izvo zvingakanganisa iyo 3.2 µm Ra kupera kunodiwa pakumanikidza vharafu yekuvharisa nzvimbo.
Iko Kukasira kwakajairwa kunokundikana — uye kuti Kurongeka kunochinja sei mhedzisiro
Vamwe vangapokana: "Kana inokodzera uye isingabvi, nei inopfuura-injiniya?" Nekuti kukundikana modes kuvanda mukushanda chaiko. Iyo yakajairwa-giredhi ductile iron pombi hwaro inogona kubata torque panguva yekuyedzwa kwefekitori-asi inodedera pa1,750 rpm mubasa remumunda, ichimhanyisa kubereka kupfeka ne40%. Yedu iron castings inoshandisa nodular graphite morphology inodzorwa kune Type VI paASTM A247, ichidzikisa vibration kutapurirana ne62% mune yechitatu-bato modal analysis.
Saizvozvo, "stainless steel casting" zvinoreva zvishoma pasina kutsanangura maitiro egiredhi. 316 isina tsvina inotadza nekukurumidza mumafuta emumunda ane chloride. Masimbi edu esimbi asina tsvina anoshandisa yakagadziridzwa 2507 super duplex-25% chromium, 7% nickel, 4% molybdenum-ine ferrite-austenite phase balance inobatwa kusvika 45-55% kuburikidza chaiyo-nguva arc monitoring panguva yekunyunguduka. Mhedzisiro: zero pitting mushure memaawa e2,000 mukufananidzirwa kuratidzwa kwegasi rakavava.
Isu hatingosangana nezviyero - isu tinomepu kuita kuti tishande. AMS 5387 cobalt alloy 6 pombi zvikamu zvinopinda mhinduro annealing pa1,175°C ±5°C, zvino kukurumidza kudzimwa kuvhara mugamma-phase kugadzikana. Post-machining, chikamu chega chega chinowana fluorescent penetrant inspection kuti ione subsurface discontinuities idiki pane 0.1 mm-nekuti kamwe kadiki-chikanganiso muhuro yehuro inogona kunyura 3 × nekukurumidza pasi peabrasive slurry flow.
Zvina Zvisina Kukurukurirana Paunenge Uchitsvaga Cast Metal Zvikamu
Kusarudza vatengesi kunoda zvinopfuura kungotora nguva dzekutungamira. Kubva pamakore gumi nemaviri anotsigira hydraulic OEMs uye vanovaka midziyo yepasi, aya mana ekutarisa anoparadzanisa vanovimbika vanobatana kubva kune vekutengesa vatengesi:
- Material certification haigone kutaurirana-kwete chete "inoenderana neASTM A48," asi mabhawa akatemerwa akaedzwa pajeti, nekuomarara kunoenderana kwakasimbiswa muzvikamu zvekukanda.
- Dimensional control inosanganisira as-cast state-CMM mishumo inofanirwa kuratidza shrinkage mvumo inoshandiswa kune dzakakomba zviboro uye zviso zvekuisa chisimbiso, kwete kungopedzwa zviyero.
- Surface kutendeseka zvinyorwa zvakakosha kupfuura nhamba dzeRa-tinoda mifananidzo yeSEM yenzvimbo dzakagadzirwa nemuchina dzinoratidza kusavapo kweakadzokorodza maseru kana diki-kubvaruka pane yakakwirira-kupfeka nzvimbo senge winch centre shaft rollers.
- Traceability inosvika pakupisa kurapwa kutenderera-machati etembiricha akaiswa pachiyero chimwe nechimwe chevira, kwete chete "kupisa kunogadziriswa maererano."
Kana mugadziri wemotokari dzeinjiniya wekuEurope achinja kune yedu cobalt alloy plugs, yavo onboard winch system MTBF yakasvetuka kubva pa4,200 kusvika 11,800 maawa ekushanda. Kwete nekuti plug "yakasimba" -asi nekuti maitiro edu ekukanda akabvisa microporosity panzvimbo yeplug-to-housing, kudzivirira kukoromoka kwemagetsi munzvimbo dzinopisa.
Zvikamu Zvesimbi Ndivo Nheyo—Kwete Kufunga Kwapera
Yepamusoro-inoshanda masisitimu inotadza pakusangana: uko imba yekukandwa inosangana nemichina shaft, uko alloy inosangana nechisimbiso, uko kuwedzera kwemafuta kunosangana nebolt preload. Cast metal parts anchor iwo mainterfaces. Kubudirira kwavo kunoenderana nesarudzo dzakaitwa pamberi pekudururwa kwekutanga-kusarudzwa kwezvinhu zvakagadziriswa kumakemikari emvura, gating dhizaini inofananidzwa nekuchinja kwemadziro, machining mvumo yakavakirwa pakusimbisa simulation-kwete post-cast kururamisa.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. inovaka zvikamu zvesimbi zvakakandwa zvekushandisa uko kutsiva kunoreva kuderera kunodhura $27,000/awa. Izvo zvinomanikidza chirango: hapana mapfupi mukusimbisa simbi, hapana fungidziro nezve "yakajairwa" kupisa kupisa, hapana kushivirira stacking pasina GD&T-inofambiswa nehurongwa hwekuronga. Zvakaguma nei? Mavharuvhu ekudzvanya anopona 50,000 cycles pa 350 bar, silinda housings inochengetedza concentricity mushure memakore gumi nemashanu ekuenderera mberi kwekushanda, mawinch shafts anounza torque isingachinji mu -40 ° C Arctic mamiriro.
Ramangwana nderezvikamu zvesimbi zvakagadzirwa—kwete kungogadzirwa—zvine chinangwa chekushanda chakabikwa mumuganhu wezviyo zvose. Izvo zvinotanga nekubvunza kwete "Inogona kukandwa here?" asi “Kunofanira kuita sei—uye ikoko kunodei kubva mukunyunguduka, kuforoma, uye muchina?”
