Lapho onjiniyela becacisa izingxenye zensimbi ezisansimbi zamavalvu adonsa amanzi, amaphampu, noma ama-winch shaft—izingxenye okumelwe ziphile emijikelezweni yokucindezela enamabha angu-300 noma ukugeleza kukawoyela ogcwele isihlabathi—abadingi nje umphakeli. Badinga uzakwethu obone i-crack efanayo isakazwa ku-AMS 5387 cobalt alloy nozzle ku-450°C. Ubani olinganise ukukhukhuleka kwe-microstructural ekushiseni okuhlanu kwezinto ezisekelwe ku-T800. Ubani owazi kahle ukuthi i-porosity yokuphonsa isihlabathi ifihla kuphi—nokuthi i-CNC finish machining ingakudalula kanjani ngaphambi kokuhlolwa kokugcina.
Kungakho ama-OEM omhlaba eNyakatho Melika naseYurophu ehlala ebuyela ku-a imboni yezingxenye zensimbi ayigxilile ngevolumu, kodwa ekuqinisekisweni: QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. Ikomkhulu layo lihlala e-Qingdao, lena akuyona isisekelo senhloso ejwayelekile. Kuyisikhungo sokukhiqiza esinembayo esakhelwe ezintweni ezintathu okungaxoxiswana ngazo—ukuphindaphindeka kobukhulu phakathi kuka-±0.015 mm kumabhores abalulekile, ukungaguquguquki kwensimbi kuwo wonke amaqoqo, kanye nokulandeleka okugcwele kusukela kusitifiketi se-billet eluhlaza kuya embikweni wokugcina we-CMM.
Amandla abo aqala ngesiyalo sezinto ezibonakalayo. Ama-alloys e-cobalt-nickel afana ne-AMS 5387 awenziwanga ngomshini—ayakhohliswa. Ukungezwani kokwanda okushisayo phakathi kwethuluzi nocezu lokusebenza, amazinga okuqinisa umsebenzi angaphezu kuka-300%, nokuhlukaniswa kwe-carbide konke kufuna ukulungiswa kwesikhathi sangempela. I-QINGDAO QIANGSENYUAN ayinikezi ukwelashwa kokushisa ngaphandle noma ithembele kumashidi wedatha yabahlinzeki abajwayelekile. Esikhundleni salokho, bahlanganisa imijikelezo yokushisa nabathengisi bezinto eziqinisekisiwe, baqinisekise inkatho ngayinye engenayo ngokumelene nosayizi wokusanhlamvu we-ASTM E112 kanye namazinga we-ASTM E381 macrostructure, futhi bagcine ukulandeleka okugcwele kweleveli ye-batch-okuhlanganisa inombolo yokuncibilika, idethi yokuthulula, nezingodo zomkhathi womlilo. Uma ikhasimende licela "i-T800-equivalent," impendulo aliyona idatha yedatha—iwukuqhathanisa okubhaliwe kwamaphrofayili okuqina, ukumelana nokugqwala kwe-intergranular nge-ASTM G28 ngayinye, nempilo yokuqhuma engu-650°C.
Lokhu kuqina kudlulela ekuhlanganisweni kwenqubo. Abahlinzeki abaningi bahlukanisa ukulingisa kanye nomshini. I-QINGDAO QIANGSENYUAN iwahlanganisa ngamabomu. Izindlu zensimbi ezisakazwa ngesihlabathi zinciphisa ingcindezi *ngaphambi* kokugaya kwe-CNC okungalungile—hhayi ngemva—ngoba izingcindezi eziyinsalela zihlanekezela i-bore geometry ngesikhathi sokuphenduka kokugcina. Imibhobho ye-cobalt esakazwa yi-investimenti ithola ukusakazwa komumo oseduze nenetha ngesibonelelo sesitoko esingu-0.3 mm, bese ithuthela ngqo kumshini we-5-axis onama-spindles apholile kanye nokuhlola okusaqhubekayo. Awekho ama-handoffs. Akukho ukukhukhuleka okulinganayo phakathi kokusebenza. Awekho amalophu okusebenza kabusha. Indawo yabo ethobela i-ISO iphatha ukuncipha kokuphonswa, ukuchezuka kwemishini, kanye nokukhula okushisayo njengokuguquguqukayo okuxhumene—hhayi izinyathelo ezingazodwa. Kungaleyo ndlela ababamba ngayo isikhundla sangempela kuma-callout e-GD&T afana nokubekezelela okuhlanganisiwe kwe-Ø0.05 mm ku-MMC kuzo zonke izici ze-datum eziyi-12 kusilinda sephampu yepiston eyodwa.
Ukwethembeka okungokoqobo kubonakala ekulethweni—hhayi nje imininingwane. Amakhasimende abika izikhathi zokuhola ezingaguquguquki kuma-oda evolumu emaphakathi (ama-pcs angu-50–500) ngenxa yokuthi ukuhlelwa kokukhiqiza kusebenzisa imephu yokugeleza komsebenzi engaqinile, hhayi izilinganiso zekhalenda. Lapho umkhiqizi wephampu waseYurophu edinga izihlalo zamavalvu zangokwezifiso ezingama-AMS 5387 ezinamajiyometri ahlukile ayi-17, ithimba lasebenzisa ubunjiniyela ngesikhathi esisodwa: ukuqinisekisa ukuhunyushwa kwe-GD&T emahoreni angama-48, lihlaba umkhosi ingxenye enezindonga ezincane ethambekele ekuhlanekezeleni ngesikhathi sokukhishwa kwesixazululo, futhi liphakamisa idizayini yokugezela eguquliwe enqamula ukulahlwa kokusakaza ngo-62%. Akukho ukubambezeleka "kokumisa idizayini". Awekho ama-oda okushintsha ngomzuzu wokugcina. Izingxenye ezisebenzayo nje, ngesikhathi, ezinamarekhodi okuhlola agcwele—okuhlanganisa nokuskena kwekhonta yokubona okumbozwe ku-CAD yegama ukuze kubonwe ukuchezuka kwemephu.
Uma ubheka phambili, ukugxila kuyalola—hhayi banzi. Batshala i-R&D ekugelezeni kokusebenza kwe-hybrid casting-machining yezingxenye zengxubevange ephezulu lapho izindlela zendabuko zifinyelela imikhawulo: cabanga ngemikhono engenasici emaphakathi eneziteshi zokupholisa zangaphakathi ezihlanganisiwe, eziqedelwe ekusetheni okukodwa kusetshenziswa izikhungo zokujika isigayo. Ukunwetshwa kwesitifiketi kuqondise izidingo eziqondene nomkhakha—i-ASME B16.34 yemizimba yamavalvu, i-API 6A yemishini ye-wellhead, EN 15085 yezicelo zesitimela—hhayi nje i-ISO 9001. Kodwa umongo uhlala ungashintshiwe: a imboni yezingxenye zensimbi lokho kukala impumelelo hhayi ngamathani athululiwe, kodwa ku-zero field ukwehluleka kumaassemblies abaluleke kakhulu. Ngoba ezinhlelweni zama-hydraulic kanye namaphampu e-oilfield, ukwethembeka akusona isici. Iwukuphela kokucaciswa okubalulekile.
