Ukukhetha a ukuphosa umzi-mveliso wensimbi engenasici ayithethi ngokufumana eyona quote isezantsi. Kumalunga nokuchonga iqabane eliqondayo ukuba ukunyamezela kwe-0.02 mm kwisitulo se-valve kuguqulela kwiinyanga ze-18 zokusebenza okungaphazanyiswa kwi-offshore hydraulic system. Siye sabona iiprojekthi ezininzi kakhulu zivaliwe-kungekhona kwiziphene zoyilo, kodwa ukusuka ekukhupheni ukungahambelani okwenzeka kuphela emva konyango lobushushu okanye ngexesha lovavanyo loxinzelelo.
Kutheni le nto ukulahlwa kwentsimbi engenastainless kufuna ngaphezu kweFoundry nje
Insimbi engenasici ayigalelwa njengentsimbi engwevu. I-chromium yayo ephezulu kunye nomxholo we-nickel yandisa i-viscosity enyibilikayo, ikhuthaza ukubunjwa kwe-oxide, kwaye iyancipha ngokuhlukileyo ngexesha lokuqina. Isiseko sokwenziwa kwamayeza enziwe afana nalawo aveliswe ngumenzi sinokubetha imichiza ecacileyo-kodwa iphose ukufana kwe-microstructural, okukhokelela ekudinweni kwangaphambi kwexesha lokuqhekeka kwizindlu zempompo ezijikelezayo okanye imingxuma yendawo kwindawo etyebileyo ngechloride. Kwiziko lethu eliseQingdao, yonke intsimbi engenasici iqala nge-AMS 5387-ehambelana ne-T800 yealloy billets-eqinisekisiweyo, iyalandeleka, kwaye iqinisekiswe kwangaphambili ubungakanani bengqolowa kunye nomxholo wokubandakanywa ngaphambi kokunyibilika kuqale.
Asikuthathi ukuphosa njengenyathelo elizimeleyo. Sisigaba sokuqala senkqubo edityaniswe ngokuqinileyo: utyalo-mali → ukuphelisa uxinzelelo → ukuchaneka kwe-CNC machining → ukuqinisekiswa kokugqibela komgangatho kwi-Zeiss Contura G2 CMM. Xa umthengi ethumela umzobo wendlu yesilinda yempompo yepiston, iinjineli zethu zijonga ngokukhawuleza ubungakanani bodonga lobungakanani ngokuchasene nedatha yokulinganisa ukuqina-kunye namacandelo eflegi apho ijometri yesanti iya kubambisa i-porosity. Ayiyothiyori leyo. Kwiprojekthi ye-oyile yaseMntla Melika, sibambe i-radius ye-fillet yangaphakathi eyi-4.2 mm eyayiza kudala indawo eshushu ngexesha lokuphosa i-centrifugal. Ukuyilwa ngokutsha ukuya kwi-6.5 mm kuphelise amazinga okwaliwa emva komatshini ngama-92%.
Ukudityaniswa okuthe nkqo kuSombulula iiNdawo zeNzululwazi zoMveliso wangempela
Uninzi lwabathengi bavelisa ukuphosa ngokwahlukileyo kumatshini- emva koko bajijisana needatum ezingalungelelanisiweyo, ukugqwetheka kwe-thermal phakathi kweenkqubo, okanye ukugqitywa komphezulu okungahambelaniyo. Silawula ikhonkco elipheleleyo. Iworkshop yethu ye-ISO 9001-certified workshop izindlu zombini ii-furnaces ze-cobalt-nickel alloys * kunye ne-5-axis DMG MORI oomatshini abakwazi ukugqiba umgangatho owenziwe ngaphakathi kwe-± 0.015 mm ngaphandle kokulungiswa kwakhona.
Olu hlanganiso luzisa iingenelo ezintathu ezinokulinganiswa:
- Uzinzo lweDimensional: I-Castings iphantsi kokupholisa okulawulwayo kwi-molds e-insulated, emva koko i-stress-relide kwi-1050 ° C ngaphambi komatshini onzima-ukunciphisa uxinzelelo olushiyekileyo ngaphezu kwe-70% ngokubhekiselele kwisiqhelo sokupholisa umoya.
- Umphezulu imfezeko: Akukho ukuqhushumba okwesibini okanye ukucholwa kweasidi efunekayo ngaphambi kokuphela kokugqibela. Iindawo zethu zesanti-cast stainless zifezekisa i-Ra ≤ 3.2 µm njenge-cast; i-investment castings ifikelela kwi-Ra ≤ 1.6 µm-ilungele i-passivation okanye i-electropolishing.
- Ukulungela ukusebenza: Iivalve zoxinzelelo zithunyelwa ngeengxelo zovavanyo lwe-hydrostatic, iilogi zokuvavanya ukuvuza, kunye ne-GD & T-ethobelayo yokuhlola iidossiers-kungekhona nje uluhlu lokutshekisha i-dimensional.
Xa Izinto “Eziqhelekileyo” Zisilela Ngokufutshane—Kwaye Umele Kwenze Ntoni Endaweni yoko
Ezinye iinjineli azigqibekanga ukuya kuma-316 angenasici kuyo yonke into. Kodwa kwizinto ezinxitywayo eziphezulu-ezifana ne-winch center shaft rollers kwiimoto zemigodi-i-316 ayinabo ubulukhuni kunye nokumelana ne-galling. Sitshintsha rhoqo nge-custom-forged 17-4PH H900 okanye i-AMS 5387 cobalt alloy, ngokuxhomekeke kwimijikelo yomthwalo kunye nokuvezwa kobushushu.
Ipompo ye-OEM yaseYurophu yakha yagxininisa kwi-304 kumzimba wevalve opholiswe ngamanzi olwandle. Iiprototypes zabo aziphumelelanga kuvavanyo lwesitshizi setyuwa emva kweeyure ezingama-320. Sicebise ukutshintshela kwi-F51 duplex i-stainless-indlela efanayo yokuphosa, isikhunta esifanayo, kodwa i-22% ephezulu ye-PREN (i-Pitting Resistance Equivalent Number). Inxalenye ehlaziyiweyo iphumelele uvavanyo lweeyure ezingama-2,000 nge-zero pitting. Iindleko zinyuke nge-14%. Ubomi bandiswe 4.7 ×. Olo rhwebo-off? Kubhalwe kwiilogbooks zabo zolondolozo.
Ukuhanjiswa okuthembekileyo kujongeka njani
“Ukuhanjiswa kwangexesha” kuthetha izinto ezahlukeneyo. Kubaphathi beentengo, ngumhla wekhalenda. Kumaqela enkonzo yasentsimini, iba neyona ndawo ingena endaweni yayo—efakwe kubushushu, ihloliwe, yaza yaphawulwa—xa isixhobo sokuvala ucingo sivaliwe. Sitshixa iifestile zokuhanjiswa ngexesha lophononongo lobunjineli, hayi emva kokuqinisekiswa kweodolo. Ukuhamba kwethu okubhityileyo kubandakanya ixesha le-buffer lokuqinisekiswa kwesinyithi, hayi ukucwangciswa koomatshini kuphela.
Ngee-odolo zeprototype, ixesha lokukhokela liqala *emva* kokuqinisekiswa kwe-GD&T—kungekhona emva kokufunyanwa kwe-PO. Kwimibaleko yomthamo ophakathi (ama-50–500 iipcs), sigcina isitokhwe semathiriyeli ekrwada kumabakala aqhelekileyo (316L, F22, 17-4PH) kwaye sibambe iipateni eziphambili zejiyometri ezili-12 ezicelwe kakhulu-kubandakanya imizimba yevalvu yoxinzelelo, iziseko zempompo, kunye nezindlu zecylinder. Oko kunciphisa amaxesha okuphinda-odolwa ngama-35% ngokomndilili.
Ukuba ufuna i ukuphosa umzi-mveliso wensimbi engenasici ephatha icandelo lakho njengenkqubo ye-mission-critical-not a commodity part-start with material traceability, funa ulawulo lwenkqubo edityanisiweyo, kwaye uqinisekise ukuba bawusingatha njani umsantsa phakathi kokucaciswa kunye nokusebenza kwehlabathi lokwenyani. Iqabane elifanelekileyo aliyi kugalela nje isinyithi. Baza kulindela ukuba uyilo lwakho ludibana phi nefiziksi-kwaye bakuncede ukuba ubhulorho.
