Lapho indlu yephampu ye-hydraulic ihluleka ngaphansi kwengcindezi yamabha angama-350, akuvamile ukuthi idizayini ibe nephutha. Imvamisa, ukungqubuzana kwe-microstructural ekubunjweni—noma ukukhukhuleka kwe-dimensional okungu-0.015 mm ngemva kokwelashwa kokushisa. Kungakho onjiniyela abathola izingxenye zensimbi ezibekezelela kakhulu bengabheki nje a ukunemba kwemboni yokutshala imali. Babheka eyodwa ephatha i-metallurgy njengekhodi: lonke ibanga le-alloy, zonke izinga lokupholisa, indawo ngayinye yokuhlola ilawulwa ngenguqulo, iyalandeleka, futhi iqinisekiswa ngokumelene nomthwalo osebenzayo-hhayi nje ukubekezelela ukudweba.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela—hhayi njengesitolo semisebenzi, kodwa njengesandiso sethimba lonjiniyela lekhasimende. Sibone amakhasimende ebuya nama-callouts e-GD&T abecabanga ukuthi i-isotropic shrinkage kuwo wonke ama-cobalt-nickel alloys. Eqinisweni, inkontileka yokulingisa ye-AMS 5387 engu-0.12% nge-axially kodwa ingu-0.07% kuphela ngesikhathi sokuqina. Lokho kungafani kwephula ukuxhumana okulingana nokucindezela ezindlini zesilinda sephampu ye-piston uma ukufakwa kwesikhunta kunganxephezeli. Ithimba lethu labasunguli lilungisa i-gating geometry nogqinsi lwegobolondo ngokusekelwe ekulingiseni okushisayo—hhayi ukuqagela—futhi likuqinisekisa ngamaqoqo esikhathi sangempela se-thermocouple ashumekwe kumagobolondo okukhiqiza.
Amakhono amathathu ahlukanisa u-caster onekhono nozakwethu obalulekile kunhlosongqangi. Okokuqala: isiyalo ngezinto ezibonakalayo. Sithola ama-alloy billets asuselwa ku-T800 cobalt kuphela ezigayweni ezigunyazwe ku-ASTM B577 kanye ne-AMS 2269, ezinamaphepha agcwele wenqwaba yokushisa. Akukho ukushintshwa "okulingana". Lapho iklayenti licela imibhobho ye-cobalt alloy yesevisi ye-abrasive slurry, sinqabe ukunikezwa kwe-“T800-grade” yomhlinzeki ngenxa yokuthi okuqukethwe kwayo kwekhabhoni kukhukhulekile ngo-0.03% ngaphezu kwe-spec—okwanele ukuze kuqalise ukugqama kwesigaba se-sigma ngemva kwamahora angu-400 ku-550°C. Okwesibili: ukulawulwa kwenqubo ye-hybrid. Ukutshala imali kukodwa akukwazi ukubamba u-±0.025 mm ku-flange yesisekelo sephampu engu-220-mm-diameter. Kodwa yihlanganise nemishini ye-CNC ye-axis emihlanu yezindawo ezibucayi zokuvala-kanye nokukhulula ukucindezeleka okuvumelanisa isikhathi phakathi kokusakazwa nomshini onzima-futhi uvala ukuqina. Okwesithathu: ukuqina kokuhlolwa. Konke ukukhishwa kwensimbi kuhlolwa nge-ultrasonic nge-ASTM E186 ngayinye; wonke umzimba wevalvu yensimbi engagqwali uthola ukuqinisekiswa kwe-CMM ezicini eziyi-12 ezibhekiselwe ku-datum ngaphambi kokuqedwa kwendawo. Sigcina izitifiketi zempahla eluhlaza, amalogi okuphatha ukushisa, futhi sixhumanisa imibiko yokulinganisa iminyaka engu-10—hhayi ngoba izindinganiso zidinga lokho, kodwa ngenxa yokuthi ukwehluleka kwenkambu kufuna ukucaciseleka ngokomthetho.
Abanye bangase baphikise ngokuthi ukwenza isihlabathi kunikeza ukulawulwa okungcono kwezindleko zezingxenye ezinkulu zesakhiwo. Lokho kuyiqiniso—ezicini lapho ukubekezelela okungu-0.3 mm kanye no-6.3 µm Ra kwamukelekayo. Kodwa uma i-winch center shaft roller yakho kufanele idlulise i-torque engu-120 kN kuyilapho izungeza ku-180 rpm ngaphakathi kwemoto yobunjiniyela echayeke emanzini anosawoti, ubuqotho bangaphandle abubuhle. Kuyimpilo yokukhathala. Ulayini wethu wokutshala imali uletha izindawo ezisakazwayo ezinesilinganiso esingu-3.2 µm Ra ezindaweni ezibucayi—akukho ukugaya kwesibili okudingekayo. Futhi ngenxa yokuthi isistimu yethu yegobolondo isebenzisa izibophezelo ze-zirconia ezizinzile ze-yttria (hhayi i-silica), siqeda ukuqhekeka okushisayo okubangelwa i-sodium ezinsimbi ze-chromium ephezulu. Lokho akulona ulimi lokumaketha. Kungakho izingxenye zethu zephampu ze-AMS 5387 zithola isivuno sokudlula sokuqala esingu-92% ekuthotshelweni kobukhulu—uma kuqhathaniswa nezilinganiso zomkhakha eziseduze nama-74%.
Asizakhi "izingxenye." Sakha ukuqhubeka kokusebenza. Ipulaki ye-cobalt alloy ayiyona nje into eyisilinda—yisithiyo sokugcina esimelene nokudlula uketshezi kuvalvu yokulawula i-downhole. Ukuminyana kwayo kufanele kudlule u-8.35 g/cm³; ubulukhuni bayo kufanele buhlale phakathi kuka-42–46 HRC ngemva kokuguga; usayizi wayo wokusanhlamvu kufanele uhlale u-ASTM 5 noma ucolekile kuso sonke isigaba esiphambene. Lokho kudinga ukulawulwa kwe-loop evaliwe kusukela kumjovo wephethini ye-wax ngokukhipha iwaxing, ukudubula, ukuthela, ukunyakazisa, kanye nokuhlanganiswa kwe-HIP. Kwa-QINGDAO QIANGSENYUAN, isinyathelo ngasinye sinemibandela echaziwe, ukuphuma ngemvume komsebenzisi, nokuloga kwedatha okuzenzakalelayo. Uma izinga lokushisa le-dewax legobolondo lichezuka ngo-±2°C, isistimu ihlaba umkhosi inkatho ngaphambi kokuthulula—ngisho noma ukuchezuka kuwela ngaphakathi “kwebanga elamukelekayo” ngokwe-ISO 9001 ngayinye. Ngoba kuyamukeleka ≠ ukulingana-nenjongo.
Uma ubheka phambili, ukucindezela akukhona nje ekubekezeleni okuqinile—kumlando wokusebenza oqinisekiswayo. Inhlanganisela yephampu yesizukulwane esilandelayo idinga ukuqondana kwamawele edijithali: ukusakaza idatha yesakhiwo esincane esivunyelaniswe namamodeli e-FEA, amaphrofayli esikhathi sangempela esishisayo afakwe kumephu ekufanisweni kwengcindezi eyinsalela, kanye nokukhukhuleka okunohlangothi okulandelelwa emijikelezweni yokukhiqiza engu-10,000+. Sishumeka izinzwa ze-IoT emabhokisini ayinhloko futhi sihlanganisa idatha ye-metrology ngokuqondile ezinhlelweni zamakhasimende ze-PLM—hhayi njengesici, kodwa njengengqalasizinda eyisisekelo. Konjiniyela abadinga okungaphezu kokucaphuna, abadinga ukubikezelwa kubhakwa kuwo wonke amagremu ensimbi: ukusesha kweqiniso ukunemba kwemboni yokutshala imali iphetha lapho izidingo zokusebenza zihlangabezana nokubulawa okubhaliwe, okuphindaphindekayo, okusekelwe ngensimbi.
