Lapho onjiniyela becacisa a imboni yokukhiqiza isihlabathi, abagcini nje ngoku-oda izingxenye zensimbi—babheja ukuzinza kwe-dimensional ngaphansi kwengcindezi ye-hydraulic yamabha angu-300, ubuqotho be-microstructure ngemva kokuhamba ngamabhayisikili okushisa, kanye nokungabekezeleli i-porosity endaweni yepompo ehamba 24/7 offshore. Lelo iqiniso esilibona nsuku zonke esitezi sesisekelo sethu e-Qingdao: indikimba yevalvu ye-cobalt-nickel yenqatshiwe—hhayi ukuze iqedwe phezulu—kodwa ngenxa yokuthi idatha ye-CMM ibonise ukuphambuka okungu-0.012 mm endaweni ebucayi yokuvala. Leyo ngxenye yabuyela ekwakhiweni kwesikhunta. Akuzona zonke izitolo ezenza lokho.
Ukulingisa Kwesanti Okusinda Ekucindezelekeni Kwangempela Komhlaba—Hhayi nje Izicaciso Zelebhu
Ukulingwa kwesihlabathi kubhalwe ngokungeyikho ngokuthi "ukunemba okuphansi" ngabantu abangakaze babambe i-AMS 5387 cobalt alloy pump casing fresh from shakeout. Siyawaphonsa. Futhi yebo—sibamba u-±0.15 mm kumadayamitha angu-300-mm, ngokuhlola okugcwele kwe-radiographic kuyo yonke imingcele yengcindezi Yesigaba II. Kanjani? Ngokulawula lokho abanye abakweqayo: umswakama wesihlabathi esiluhlaza ku-3.2–3.6%, isilinganiso sesibopho sobumba silinganiswa ngeqeqebana ngalinye, nezinga lokushisa lebhokisi eliwumgogodla lizinze phakathi kuka-±2°C phakathi nokudubula okuyinhloko. Asigcini nje ngokuthela insimbi encibilikisiwe. Siphatha ama-thermal gradients kuwo wonke umgodi wokukhunta ukuze ukuncipha kudonseleka ngokufanayo ezindaweni eziphakemeyo—hhayi ezindaweni zokusebenza.
Lokhu kubaluleke kakhulu ezingxenyeni ezifana nezindlu zesilinda sephampu ye-piston noma amarola we-winch centre shaft yemoto yobunjiniyela. Lezi akuzona izingxenye ezimile. Zizungeza ngaphansi komthwalo we-torsional ngenkathi zithwala i-axial thrust evela kuketshezi olunomfutho ophezulu. Ukufakwa okungu-0.05 mm eduze kwe-fillet radius kuba isayithi lokuqalisa ukukhathala emahoreni okusebenza angu-1,200. Inqubo yethu yokukhipha isihlabathi ihlanganisa ukuqapha okungaphakathi kwesikhunta se-thermocouple kukho konke ukuthululwa okubucayi, futhi konke ukubunjwa kuhlolwa nge-ultrasonic ngaphambi komshini—ngisho nasezingxenyeni ezingenawo ingcindezi. Ngoba ukwehluleka akuyona kanambambili. Kuyaqoqwa.
Lapho Ukugaywa Kwesihlabathi Kuhlangana Nemishini Enembayo—Akukho Ukunikezwa Kwesandla, Azikho Izikhala
Amanye amafekthri enza imishini yangaphandle. Asazi. Kungani? Ngoba i-sand-cast steel flange ene-1.2 mm machining allowance ayisebenzi ngendlela efanayo neno-0.8 mm—ikakhulukazi uma uhlanganisa i-M42×3.5 ku-baseplate yensimbi engagqwali ukuze kusebenze i-valve engaphansi kolwandle. Amaseli ethu e-CNC ahlala amamitha ayi-15 ukusuka esiteshini se-shakeout. Ama-castings ahamba aqonde ngqo ezigayweni eziyisicefe ezivundlile ezisetshenziswa bukhoma, hhayi endaweni yokugcina impahla ukuze kuhlelwe kabusha.
Sisebenza ngomshini esikuphonsayo—futhi siphonsa esikwaziyo ukuthi kwenziwa kanjani ngomshini. Lokho kuhlanganiswa okuqondile kusho ukuthi azikho izimanga esigabeni sokubuyekeza i-GD&T. Uma ikhasimende lithumela umdwebo ofuna ukubekezelela indawo engu-Ø0.05 mm ezimbobeni zamabhawodi ayisithupha ngokuhlobene nendawo yedatha ye-sand-cast, asiceli ireferensi yomshini. Sakha iphethini ngesinxephezelo esisalungiswa, silawula amandla okubumbana kwesikhunta abe ngu-±3%, futhi siqinisekisa ukuvuleka okusakazwayo ngaphambi kokubamba. Bese sisebenza ngomshini—sisebenzisa ama-probe afakwe kwi-fixture ukuze sinxephezele ngokuzenzekelayo ukushintshashintsha kokusakaza okuncane. Umphumela? Ukuthobela i-athikili yokuqala ku-92% wama-oda wevolumu emaphakathi. Akukho ukuzama kwesibili. Akukho ukuyekwa kobunjiniyela.
Izinto Ongazethemba—Hhayi Izitifiketi Kuphela Ongazifayela
Impahla eluhlaza eqinisekisiwe iyisiteki setafula. Okuhlukanisa abahlinzeki abathembekile ukulandeleka *ngaphansi* kwesitifiketi. Kumabhomu engxubevange e-T800 esekelwe ku-cobalt, silandelela inombolo ngayinye yokushisa kusukela ekuhlaziyweni kweladle yomhlinzeki ngokuqinisekiswa kwethu kwe-spectrographic, bese sikumephu ekulingiseni ngakunye sisebenzisa amakhodi elotho afakwe nge-laser. Uma umlomo wombhobho wehluleka ukuhlola inkambu, sidonsa wonke umlando wayo oshisayo—hhayi nje umbiko wayo oqinile.
Sithola amabhilidi e-AMS 5387 kuphela ezigayweni ezinezitifiketi zokugaya ze-EN 10204 3.2—futhi sihlole okuqukethwe kwekhabhoni, i-chromium, nokuqukethwe kwe-tungsten nge-OES ngaphambi kokuthela. Kungani? Ngoba u-0.03% wekhabhoni eyeqile ku-cobalt alloy wehlisa ubulukhuni bokushisa ngo-18% ngaphezu kuka-600°C. Lowo umehluko phakathi kombhobho osinda emijikelezweni engu-14,000 empompini yomjovo wamakhemikhali wezinga eliphezulu… noma yehluleka ku-8,200. Siyahlola. Siyaqopha. Sithatha isinyathelo.
Ilogi yethu yezinto ezibonakalayo ihlanganisa:
- Inombolo yokushisa yomhlinzeki kanye nedethi yokuncibilika
- Ukuqinisekiswa kwethu kwe-OES okungenayo (okunokuphrinta okuyisisekelo okugcwele)
- Isabelo somgodi wesikhunta futhi uthele i-ID yokulandelana
- Imephu yobulukhuni be-post-heat-treat kuzo zonke izigaba ezintathu
- Iskena sokugcina se-CMM esinembondela yokuchezuka kombala iqhathaniswa ne-CAD
Azikho izikhala. Akukho ukucabanga.
Kungani Onjiniyela Bomhlaba Wonke Bakhetha Le Factory Yokukhiqiza Isihlabathi
Ama-OEM asendaweni kawoyela aseNyakatho Melika a-oda kithi ngoba siletha i-prototype iron casting ezinsukwini eziyi-18—hhayi amaviki ayi-6—ngamadokhumenti agcwele e-ASME Isigaba VIII Ingxenye UHA. Izihlanganisi zesistimu ye-hydraulic yase-Europe zisebenzisa ukusakaza kwethu kwensimbi ngoba siqinisekisa i-weld prep geometry *ngaphambi* kokuthela, siqeda ukugaya kwangemuva kokushisela ekushiseleleni komngcele wengcindezi. Izihlanganisi zephampu zaseNingizimu-mpumalanga ye-Asia zithembele kithi ukuze zithole amapulaki e-cobalt alloy ngoba sibambe i-Ra ≤0.4 µm ebusweni obuvaliwe—ngaphandle kokuxhuma kwesibili—ngokuthuthukisa isiphetho sesikhunta kanye nedizayini yesango.
Ukwethembeka lapha akulona ulimi lokumaketha. Izinga le-scrap elingu-0.00% ku-420+ AMS 5387 wezindlu zamaphampu ezithunyelwe ngekota yokugcina. Kungu-100% ukulethwa ngesikhathi kwezinyanga ezingama-27 zilandelana. Iqiniso lokuthi uma ikhasimende libuza, “Ingabe ungabamba isikhundla sangempela kulezi zimbobo ezinentambo engu-12 ngemva kokusakaza nokushisa?”—siphendula ngemephu yenqubo, hhayi ithemba.
Uma uhlelo lwakho lokusebenza ludinga okungaphezu nje kokuthi “insimbi esesimweni”—uma idinga i-metallurgy ebikezelwayo, i-geometry eqinisekisiwe, nokuziphendulela kwe-zero-compromise—khona-ke ilungelo imboni yokukhiqiza isihlabathi akuyona eshibhe kakhulu. Yiyona ephatha ingxenye yakho njengehadiwe elibalulekile kumishini kusukela ngosuku lokuqala. Yilokho esikwenzayo. Njalo thela. Yonke ingxenye. Zikhathi zonke.
