Xa indlu yempompo ye-hydraulic ingaphumeleli phantsi koxinzelelo lwe-bar ye-350, kunqabile ukuba uyilo olunephutha. Amaxesha amaninzi, kukungahambelani kwe-microstructural kwi-casting-okanye i-0.015 mm dimensional drift emva konyango lobushushu. Yiyo loo nto iinjineli ezifumana iinxalenye zetsimbi ezinokunyamezelana zingakhangeli nje a umzi-mveliso wokugalela imali ochanekileyo. Bajonge enye ephethe i-metallurgy njengekhowudi: ibakala ngalinye le-alloy, isantya ngasinye sokupholisa, yonke indawo yokuhlola ilawulwa yinguqulelo, iyalandeleka, kwaye iqinisekisiwe ngokuchasene nomthwalo osebenzayo-kungekhona nje ukunyamezela ukunyamezela.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela-hayi njengevenkile yomsebenzi, kodwa njengokwandiswa kweqela lobunjineli bomthengi. Sibone abathengi bebuya neefowuni ze-GD&T ezicingela ukushwabana kwe-isotropic kuzo zonke iialloyi ze-cobalt-nickel. Enyanisweni, i-AMS 5387 castings contract 0.12% axially kodwa kuphela i-0.07% ye-radially ngexesha lokuqina. Oku kungafaniyo kophula unxibelelwano olulungelelanisiweyo kwizindlu zempompo yepiston ukuba isixhobo sokungunda asibuyiseli. Iqela lethu le-Foundry lihlengahlengisa i-geometry ye-gating kunye nobukhulu beqokobhe ngokusekwe kukulinganisa kwe-thermal-hayi uqikelelo-kwaye iyayiqinisekisa nge-real-time thermocouple arrays efakwe kumaqokobhe emveliso.
Izakhono ezithathu zahlula umntu okwaziyo ukudlala kwi-caster kwi-mission-critical partner. Okokuqala: uqeqesho lwezinto eziphathekayo. Sifumana i-T800 cobalt-based alloy billets kuphela kwii-mills eziqinisekisiweyo ukuya kwi-ASTM B577 kunye ne-AMS 2269, kunye namaxwebhu agcweleyo obushushu. Akukho "elingana" substitution. Xa umxhasi ecela imilomo yengxubevange ye-cobalt yenkonzo eludaka oluludaka, siye sakhaba umboneleli we-"T800-grade" yomboneleli ngenxa yokuba umxholo wekhabhoni ukhukuliseke nge-0.03% ngaphezulu kwe-spec-eyoneleyo ukuvusa i-sigma-phase embrittlement emva kweeyure ezingama-400 kwi-550 °C. Okwesibini: ulawulo lwenkqubo ye-hybrid. Utyalo-mali lulodwa alukwazi ukubamba i-±0.025 mm kwi-220-mm-diameter ye-flange yesiseko sempompo. Kodwa yidibanise ne-five-axis CNC machining yeendawo ezibaluleke kakhulu zokutywina-kunye nexesha-synchronized stress-relief phakathi kokuphosa kunye nomatshini orhabaxa-kwaye utshixa uzinzo. Okwesithathu: ukunyanzeliswa kokuhlolwa. Yonke intsimbi yokuphosa ivavanywa nge-ultrasonic nge-ASTM E186; wonke umzimba wevalve yentsimbi engenastainless ufumana ukuqinisekiswa kweCMM kwiimpawu ezili-12 ezibhekiselele kwidatum ngaphambi kokugqitywa komphezulu. Sigcina ii-certs zemathiriyeli ekrwada, iilog zokuphatha ubushushu, kwaye silungelelanisa iingxelo zokulinganisa iminyaka eyi-10-hayi ngenxa yokuba imigangatho ifuna oko, kodwa ngenxa yokuba ukusilela kwebala kufuna ukucaciswa kwenkundla.
Abanye banokuxoxa ukuba ukuphosa kwesanti kunika ulawulo olungcono lweendleko kwiindawo ezinkulu zesakhiwo. Yinyani leyo-kumacandelo apho ukunyamezela kwe-0.3 mm kunye ne-6.3 µm Ra umphezulu wokugqiba kwamkelekile. Kodwa xa i-winch centre shaft roller yakho kufuneka isasaze i-torque ye-120 kN ngelixa ijikeleza nge-180 rpm ngaphakathi kwemoto yobunjineli evezwe kumanzi etyuwa, ingqibelelo yomphezulu ayisiyonto yokuthambisa. Bubomi bokudinwa. Umgca wethu wotyalo-mali unikezela ngemigangatho engumndilili we-3.2 µm Ra kwiindawo zokunxiba ezibalulekileyo-akukho kugaya okwesibini kuyadingeka. Kwaye ngenxa yokuba inkqubo yethu yeqokobhe isebenzisa i-yttria-stabilized zirconia binders (hayi i-silica), siyayiphelisa i-sodium-induced hot cracking kwi-high-chromium steels. Ayilolwimi lokuthengisa olo. Yiyo loo nto iipompo zethu ze-AMS 5387 zifikelela kwi-92% yesivuno sokuqala ekuthotyelweni komgangatho-ngokuchasene nemiyinge yoshishino kufutshane ne-74%.
Asazi "iinxalenye." Sakha ukuqhubeka komsebenzi. Iplagi ye-cobalt alloy ayiyona nje i-cylindrical efakwe-yinto yokugqibela yokuthintela ukukhutshwa kwamanzi kwi-valve yokulawula i-downhole. Ubuninzi bayo kufuneka budlule kwi-8.35 g/cm³; ubulukhuni bayo kufuneka buhlale phakathi kwe-42-46 HRC emva kokuguga; ubungakanani bayo obuziinkozo kufuneka buhlale be-ASTM 5 okanye bucoleke kulo lonke icandelo elinqamlezileyo. Oko kufuna ulawulo lwe-loop evaliweyo ukusuka kwisitofu sepateni ye-wax ngokusebenzisa i-wax, ukudubula, ukugalela, i-shakeout, kunye nokuhlanganiswa kwe-HIP. Kwi-QINGDAO QIANGSENYUAN, inyathelo ngalinye lichaze iiparameters, ukusayinwa komsebenzisi, kunye nokuloga kwedatha ngokuzenzekelayo. Ukuba iqokobhe iqondo lobushushu be-dewax liyaphambuka ngo ±2°C, inkqubo iflegi iqashiso phambi kokugalela-nokuba ukutenxa kuwela ngaphakathi “kuluhlu olwamkelekileyo” ngokwe-ISO 9001.
Ukujonga phambili, uxinzelelo alukho kunyamezelo olungqongqo- lukwimbali yokusebenza eqinisekisiweyo. Iindibano zempompo zesizukulwana esilandelayo zifuna ulungelelwaniso lwamawele edijithali: ukuphoswa kwedatha ye-microstructure engqanyaniswe neemodeli ze-FEA, iiprofayili zexesha lokwenyani ezifakwe kwimaphu zokulinganisa uxinzelelo, kunye ne-dimensional drift elandelwayo kwi-10,000+ yomjikelezo wemveliso. Sifakela izinzwa ze-IoT kwiibhokisi ezingundoqo kunye nokudibanisa idatha ye-metrology ngokuthe ngqo kwiinkqubo ze-PLM zabathengi-kungekhona njengento, kodwa njengesiseko sesiseko. Iinjineli ezifuna ngaphezulu kwesicatshulwa, ezidinga uqikelelo olubhakiweyo kuyo yonke igram yentsimbi: uphendlo lwenyani umzi-mveliso wokugalela imali ochanekileyo iphela apho iimfuno zokusebenza zidibana khona nokubhalwa, okuphindaphindwayo, okusekelwe kwisinyithi.
