Xa iinjineli zichaza a imveliso yokuphosa imveliso, abagcini nje ngokuyalela iinxalenye zetsimbi-babheja ngokuzinza kwe-dimensional phantsi kwe-350 yoxinzelelo lwe-bar, ukunyaniseka kwe-microstructure emva kokuhamba ngebhayisikili yokushisa, kunye nokunyamezela kwe-zero kwi-porosity kwi-cobalt-alloy pump housing. Sibone iiprojekthi ezininzi zilibazisekile ngabaseki abaphatha ukuphosa njengenkqubo yorhwebo-kungekhona uqeqesho lwesinyithi. Yiyo loo nto amacandelo achanekileyo-abalulekileyo kwiinkqubo ze-hydraulic, izixhobo ze-oyile engaselunxwemeni, kunye ne-winch-duty-duty drives zifuna ngaphezulu kokubumba kwesanti kunye ne-CNC mill. Bafuna ukudityaniswa: kwenzululwazi yezinto eziphathekayo, ulawulo lwenkqubo, kunye nokuqinisekiswa kokusebenza.
Kutheni ukuphosa kungekuko nje ukugalela isinyithi-kumalunga nokusebenza okuqikelelweyo
Uninzi lwabathengi bacinga ukuba "ukwenza isiko" kuthetha ukulungisa umzobo kunye nokulinda iiveki ezintandathu. Enyanisweni, inqaku lokuqala lokungaphumeleli akusiyo into yokuthululela-kukukhethwa kwezinto eziphathekayo. Indlu yesilinda yepompo yepiston eyenziwe kwi-ASTM A48 Udidi lwe-35 yentsimbi engwevu ayisayi kusinda kumothuko we-thermal kuvavanyo lomjikelo ophezulu wehydraulic. Ngokunjalo nomzimba wevalvu yentsimbi egqwesileyo engama-316 awusayi kuxhathisa ukhukuliseko olusuka kuludaka oluludaka kwi-120°C. Siye saqinisekisa oku kuwo wonke ama-217 kwi-deployments field: amabanga angahambelaniyo e-alloy abangela i-68% yokungaphumeleli kokunxiba kwangaphambili-kungekhona impazamo yomatshini okanye isiphene soyilo.
Isisombululo siqala ngaphambi kokuba iphethini isikwe. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke isicatshulwa sokuphosa sibandakanya ukuhlaziywa kwe-metallurgical: iithagethi zobungakanani beenkozo, imida yokwahlula phakathi kwe-interdendritic, kunye nemodeli yokuqinisa kumacandelo abalulekileyo. Kwi-AMS 5387 i-cobalt alloy components, sifaneleka kwangaphambili iibhilithi eziluhlaza kunye nohlalutyo lwe-spectrographic kunye novavanyo lwe-ultrasonic-kuba i-batch-to-batch consistency kwi-cobalt-nickel alloys ichaphazela ngqo ubomi bokukhathala kwiindawo ezijikelezayo zempompo. Akukho ndlela zimfutshane. Akukho kutshintshwa “kwibakala elisemgangathweni”.
Iindidi ezine zeMveliso-Nganye Yakhelwe kwiiNdlela zokuSebenza zokuSebenza
Unikezelo lwethu oluphambili ayilohlelo olungenasizathu. Benza imephu ngokuthe ngqo kwiimeko zoxinzelelo zehlabathi lokwenyani:
- CNC oomatshini iindawo: Apho ukuphosa kukodwa kungenakubamba ± 0.015 mm GD&T callouts kwindawo yokutywina-ingakumbi emva kokugqwethwa konyango lobushushu
- Amacandelo e-cobalt-nickel alloy: Ngokukodwa imilomo ye-T800-grade kunye neeplagi ezixhathisa i-galling kwi-650 ° C kwizixhobo zokubuyisela ioli ezincediswa ngumphunga
- Ukuphoswa kwentsimbi: Ubunjineli obungwevu kunye nentsimbi ye-ductile ene-nodularity elawulwayo yeziseko zempompo ezingcangcazelisayo
- Intsimbi kunye neesanti zentsimbi: ASTM A216 WCB kunye ne-A351 CF8M izindlu ezifanelekileyo kwi-NACE MR0175 ngenkonzo emuncu
Qaphela ipateni? Onke amacandelo aphendula umbuzo: "Yintoni eyoyisakala kuqala-kwaye siyimisa njani?" I-winch center shaft roller ayikho nje ingqukuva-kufuneka igcine ubulukhuni ngemijikelo ye-10,000 yomthwalo ngelixa ixhathisa i-ground pitting. Oko kufuna i-graphite morphology elawulwayo kwi-casting * kunye * ne-post-machining shot peening-hayi nje ukunyamezela "okulungileyo ngokwaneleyo".
Ukuthotyelwa kwe-ISO kuthetha ukuba akukho nto ngaphandle kokulandeleka onokuthi uyiqinisekise
“Iziko le-ISO-certified” livela kwisiqingatha sewebhusayithi yomboneleli we-casting esiphicothayo. Kodwa isatifikethi asiqinisekisi ukuba inombolo yobushushu yeplagi ye-AMS 5387 yakho ihambelana nengxelo yayo yokuqina-okanye ukuba idatha ye-CMM yokuskena yedayamitha yesihlalo sevalve yabanjwa *phambi kokusila kokugqibela. Sifakela umkhondo wokulandelelana komsebenzi: ukuphosa ngakunye kuphethe i-ID efakwe kwi-laser edibanisa nelogi yayo enyibilikayo, indawo yokugcina ifilimu yeradiographic, kunye nengxelo yokugqibela yokuhlola. Abathengi bafikelela kumaxwebhu apheleleyo nge-portal ekhuselekileyo-hayi iiPDF ezithunyelwe nge-imeyile xa zithunyelwa.
Sikwala uluhlu lokukhangela lwe-QC oluthi "ubukhulu obunye". Umbhobho we-cobalt-alloy ungena kwi-liquid penetrant + microhardness mapping kwiindawo ezintathu zeradial. Isiseko sempompo yentsimbi sifumana uhlalutyo lokungcangcazela ngexesha lomatshini orhabaxa ukukhangela i-voids yangaphakathi ephoswe yiX-reyi. Oku ayisiyiyo i-overkill-yindlela esiyigcina ngayo zero imbuyekezo yommandla ku-mission-critical components hydraulic kwiinyanga ezingama-42 ezidlulileyo.
Ukusuka kuMzobo woPhononongo ukuya kuHambiso-Akukho bhokisi zimnyama, akukho nto imangalisayo
Iinjineli azifuni omnye umthengisi othi "ewe" emva koko athethathethane ngokunyamezelana phakathi kwenkqubo. Uphononongo lwethu lobunjineli lubonisa imingcipheko yokwenza *phambi* kokucaphula: uguquko lobungakanani bodonga olumema ukukrazuka okushushu, ii-engile eziyidrafti ezingahambelani namandla otyalo-mali, i-GD&T callouts ezingqubana nokulahla izibonelelo zokucutheka. Sibuyisela imizobo ecacileyo-kunye nezinye, kungekhona nje imigca ebomvu.
Ukuqhuba kweprototype, ixesha lokukhokela ziintsuku ezingama-22-28-hayi "iiveki ezi-4-6." Kwii-odolo zomthamo ophakathi (ii-50–500 iipcs), sitshixa umthamo sisebenzisa isicwangciso sexesha letakt esibhityileyo, hayi ukucwangciswa okunethemba. Kwaye ewe-sithumela imithwalo encinci ukuba umthengi ufuna iyunithi yovavanyo olusebenzayo ngaphambi kwemveliso epheleleyo. Ngenxa yokuba ukuthembeka akukhona nje inxalenye. Imalunga nentsebenziswano.
Ukuba iprojekthi yakho elandelayo ibandakanya iivalvu zoxinzelelo oluphezulu, i-cobalt-alloy pump yangaphakathi, okanye ulwakhiwo olufuna ukunyamezelwa kwe-ISO 2768-mK, qala ngokuziphatha okubonakalayo-hayi ubuncinci bomthamo womyalelo. Yinyani imveliso yokuphosa imveliso ayilindi iinkcukacha. Ilindele iindlela zokungaphumeleli, iqinisekisa i-metallurgy, kunye neenqanawa ezinokulandeleka onokuthi uziphicothe-hayi ukuthembela nje.
