Xa iinjineli zicacisa iinxalenye zetsimbi ezinokunyamezela okuphezulu kwiivalvu zehydraulic, izindlu zempompo, okanye i-oyile engaselunxwemeni kunye nenkqubo yegesi, ayifuni nje Umzi-mveliso wabaxhasi ochanekileyo wotyalo-mali—badinga enye *exela kwangaphambili iindlela zokungaphumeleli phambi kokuba kuqale ukuphosa*. Siye sabona iiprojekthi ezininzi zilibazisekile ngokuqhutywa yidimensional drift in cobalt alloy nozzles or microstructural inconsistencies in AMS 5387 pump components. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yonke inxalenye iqala ngenjongo ye-metallurgical-hayi nje ukunyamezela idimensional.
Kutheni “Ukuchaneka” Kuqala Kwakudala Ngaphambi Kokugalelwa Umngundo
Ukuchaneka okuyinyani kotyalo-mali akukho malunga nokubetha ± 0.05 mm kwingxelo yeCMM. Kumalunga nokulawula izinto eziguquguqukayo uninzi lwababoneleli abaluphatha njengengxolo yangasemva: i-thermal gradient ngexesha lokuqiniswa kwepatheni yewax, i-ceramic shell permeability kwi-1,150 ° C, kunye nokusabalalisa uxinzelelo olushiyekileyo emva kokunyangwa kobushushu be-T800 cobalt-based castings. Sihlala sidibana nabathengi abafumene iindawo "eziqinisekisiweyo" ze-AMS 5387-kuphela ukufumana ulwahlulo lomda we-carbide ngexesha loxinzelelo lokuhamba ngebhayisikile. Yiyo loo nto inkqubo yethu ibethelela ukulandeleka kwezinto *phambi* kokunyibilika: indawo nganye yobushushu iphethe idatha yespectrographic epheleleyo, iigophe eziqinileyo, kunye nezigodo zovavanyo lwe-intergranular corrosion-hayi nje isatifikethi sokusila.
Siqinisekisa oku yonke imihla. Kwinyanga ephelileyo, i-OEM yaseYurophu isithumelele iibhetshi ezintathu ezikhatyiweyo zepiston pump cylinder housings-ezimbini kwiifektri ezikhuphisanayo, enye kuthi. Zonke zidibene ne-GD&T ngomzobo ngamnye. Kodwa kuphela eyethu iphumelele uvavanyo lonyamezelo olusebenzayo kwibha ye-420 kwimijikelezo ye-12,000. Ngoba? Ngenxa yokuba silawula amazinga erempu yokungunda ngaphakathi kwe-± 3 ° C / min kwaye sibambe ukufuma okomisa iqokobhe ngaphantsi kwe-35% ye-RH-iparamitha azifane zibhalwe kwenye indawo kodwa zibaluleke kakhulu ekunciphiseni i-microporosity kwiindawo ezityebileyo zentsimbi engenasici.
Udibaniso oluthe nkqo olunikezela ngozinzo
Uninzi "lwenkonzo epheleleyo" yamaziko avelisa oomatshini okanye ukugqiba. Oko kudala izithuba ze-handoff-dimensional handoff-ingakumbi yingozi xa uguqula i-320HB yezindlu ezingenasici zibe yi-45HRC elukhuni kunye ne-± 0.015 mm cylindricity. Iziko lethu le-ISO elithobelayo linezindlu ze-CNC lathes, amaziko okusila akwi-axis amahlanu, kunye neziko lokucoca ubushushu phantsi kophahla olunye. Akukho mthengisi wangaphandle utshintsha imbali ye-thermal yeplagi yakho ye-cobalt-nickel phakathi kokuphosa kunye nokugaya okokugqibela.
- Amaziko omatshini e-CNC alungelelaniswa yonke imihla ngokuchasene ne-NIST-traceable masters
- Ukuhlolwa kwenkqubo kwiinqanaba ezi-3 ezibalulekileyo: i-post-rough, i-post-heat-treat, i-post-finish
- Umlinganiselo wokujonga iicontours ezintsonkothileyo (umzekelo, iirola zeshaft ezingeyosetyhula)
- Ukuqinisekiswa kwengqibelelo yomphezulu nge-interferometry yokukhanya okumhlophe-hayi nje amaxabiso eRa
Oku kudityaniswa kuphelisa "i-stack-stack-up" ebulala ukuthembeka kwinqwelo yobunjineli kwi-winches. Xa umthengi ecela i-roller yesiko kunye ne-asymmetric ethwele umthwalo wejometri, siye saqhuba ukulinganisa, senze umatshini wokuqala we-prototype endlini, kunye nokuqinisekiswa kokuthwala ubomi kwi-hydraulic fatigue rig yethu-konke ngeentsuku ze-11 zokusebenza. Akukho kulibaziseka kwekhuriya. Akukho datham ezingalungelelanisiweyo.
Apho ubuNgcali boMathiriyeli budibana neeNdlela zoKusilela zokwenyani zeHlabathi
Abanye ababoneleli baphatha i-cobalt alloys "njengenye i-superalloy." Sibaphatha njengeenkqubo ezinemisayino yokusilela echaziweyo. Imilomo yengxubevange ye-Cobalt ayiphumeleli ekuqhekekeni okugqithisileyo-kodwa ukusuka kukhukuliseko lwasekhaya kwi-engile yempembelelo ye-12-15 ° kwinkonzo ye-abrasive slurry. Ke sihlengahlengisa ukuqina komkhombandlela ukulungelelanisa iingalo ze-dendrite perpendicular to flow paths. Iiplagi ze-AMS 5387 zithobisa kungekhona ekulahlekeni kwamandla esivuno-kodwa ukusuka kwi-sigma isigaba semvula kwi-650-850 ° C ngexesha lokulungiswa kwe-welding. Ke ngoko sifanelekela ngaphambili zonke iintambo zokugcwalisa ngeetshathi zexesha lobushushu-utshintsho (TTT).
Kungenxa yoko le nto i-iron castings yethu yesiseko sempompo ibandakanya iingxelo ze-graphite morphology-kwaye kutheni i-stainless steel castings yethu ihambisa iimephu ezinenombolo ye-ferrite (FN), kungekhona nje uhlalutyo lweekhemikhali. Asicingi; silinganisa. Kwaye sabelana ngaloo milinganiselo.
Eyona nto uyifumanayo-hayi nje le nto uyithembisileyo
A ethembekileyo Umzi-mveliso wabaxhasi ochanekileyo wotyalo-mali inikezela ngaphezu kwamalungu. Inika ukucaca kwesigqibo. Xa usithumelela umzobo we-GD&T, uyabuya:
- Uvavanyo lomngcipheko oluphezulu luqaqambisa iimpawu ezibuthathaka kakhulu ekushwabaneni okanye ukugqwetheka kokungunda
- Iinketho zokutshintshwa kwezinto eziphathekayo kunye norhwebo oluqinisekisiweyo lwentsebenzo (umzekelo, i-F316L vs. F347H yokulayisha ngokushushu okujikelezayo)
- Ixesha elikhokelayo elubala: iprototype (iintsuku ezingama-22), umthamo ophakathi (iiveki ezi-6-8), kunye ne-buffer eyakhelwe ukulibaziseka kwesiqinisekiso sezinto ezikrwada.
- Ukulandelwa kwebhetshi epheleleyo: ilog enyibilikayo, iqashiso lokuphosa, itshati yomjikelo wokuphatha ubushushu, ingxelo yeCMM, ukuqinisekiswa kokugqiba komphezulu
Akukho nto imangalisayo. Hayi "siya kujonga ngemveliso." Izigqibo zobunjineli nje ezisekelwe kwindlela yokuziphatha—kungekhona kwiincwadana ezinemifanekiso.
Ukujonga Phambili: Ukuchaneka Okuguquguqukayo, Hayi Ukuphindaphinda nje
Umda olandelayo awunyamezeli kakhulu-kukuchaneka okuguquguqukayo. Sandisa i-R&D kwiinkqubo ze-hybrid casting-machining apho utyalo-mali olusondele kwimilo yotyalo-mali lufumana ukunyibilika kwe-laser kwimigangatho yokunxiba yendawo. Siphinde siqinisekise kwi-API 6A PR2 kunye ne-ISO 15156 Annex A kwizicelo zenkonzo emuncu-kuba ukuthembeka kuthetha ukuhlangabezana nomgangatho *ngaphambi kokuba* kufike uphicotho.
Ukuba isicelo sakho sifuna iivalvu zoxinzelelo ezitywina kwi-700 bar, i-cobalt alloy components esinda kwiiyure ze-10,000 kwi-corrosive brine, okanye i-winch shafts ephethe imithwalo ye-asymmetric shock ngaphandle kokusasazwa kwe-microcrack-udinga iqabane elichaza "ukuchaneka" kubandakanya indlela inxalenye eziphatha ngayo * emva kokuba ishiya i-factory. Lowo ngumgangatho esiyakhela kuwo. Yonke imihla.
