Lapho onjiniyela becacisa a imboni ekhethekile yensimbi engagqwali, abafuni nje omunye umphakeli wensimbi. Basesha umaqondana oqondayo ukuthi kungani i-AMS 5387 cobalt alloy pump housings crack ngaphansi kokuhamba ngebhayisikili eshisayo—noma ukuthi imibhobho esekelwe ku-T800 igcina kanjani ubulukhuni ku-800°C kuyilapho imelana ne-sulfid endaweni yegesi emuncu. Lelo zinga lokuqonda aliveli kumakhathalogi noma izinjini zokucaphuna ezizenzakalelayo. Iphuma kumavavu okucindezela omshini abona amabha angu-420 nsuku zonke, asakaza izindlu zamasilinda epompo ye-piston ezinogqinsi olungaphansi kuka-4.2 mm, futhi aqinisekise ama-callout e-GD&T kumarola we-winch center shaft lapho ukuphuma kwe-±0.015 mm kuthinta ngokuqondile ukuphila kokubola kwekhebula.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngale ndlela—hhayi njengesitolo semisebenzi, kodwa njengesandiso sethimba lonjiniyela. Isekelwe e-Qingdao, e-China, inkampani yazakhela igama layo ekuxazululeni izinkinga abanye abazigwemayo: izingxenye ezenziwe ngama-superalloy agaya inyongo kumathuluzi ajwayelekile e-carbide, amajiyometri adinga kanyekanye i-5-axis contouring kanye ne-microstructure elawulwa ngokushisa, kanye nemihlangano lapho ukumelana nokugqwala kufanele kuhambisane namandla okukhathala ngemva kuka-50,00000. Indawo yayo ethobela i-ISO ayilungiselelwanga umthamo—ilungiselelwe ukuphindaphindwa kwezinhlelo zokusebenza eziphakeme kakhulu: izindawo eziningi zokulawula indawo kawoyela, amawintshi asolwandle asebenzisa amanzi amaningi, kanye nezinhlelo zamaphampu ezibuyisela ingcindezi eNyakatho Melika, eYurophu, naseNingizimu-mpumalanga ye-Asia.
Amakhono amathathu ahlukanisa lokhu imboni ekhethekile yensimbi engagqwali kusuka kubakhiqizi benhloso ejwayelekile. Okokuqala, ubuciko bezinto ezibonakalayo ngaphezu kwemininingwane yedatha. Onjiniyela abagcini ngokukhetha “insimbi engagqwali”—bakhetha phakathi kwe-F51 duplex yokumelana ne-chloride pitting, 17-4PH yokuqina kwe-shaft eqinile, noma i-cobalt-nickel ye-T800 encibilikisiwe ngokwezifiso yokumelana nokuguguleka kumaphampu ancibilikayo anodaka. Imithombo ye-QIANGSENYUAN ithola ama-ingots aqinisekisiwe, iqinisekisa ikhemistri nge-ASTM E1479 ngayinye, futhi isebenzisana ngokuqondile nama-metallurgists ukulungisa usayizi wokusanhlamvu nokuqukethwe kwe-delta ferrite—ngoba ukuhluka okungu-0.3% ku-nitrogen kungashintsha amandla okukhiqiza ngo-110 MPa ekubunjweni kwe-duplex.
Okwesibili, ukuhlanganisa okuqondile okususa amaphutha we-handoff. Abahlinzeki abaningi bakhipha izinsiza, ukwenza imishini, nokuqeda. Lapha, ama-plugs e-cobalt alloy afaka utshalomali asuka ngqo esithandweni segobolondo aye kumaseli e-CNC afakwe amathuluzi enzwa ngamandla—akukho kulungiswa kabusha, akukho kushintsha kwe-datum. Izisekelo zephampu ezisakazwa ngesihlabathi zikhulula ingcindezi ngaphambi komshini onzima, bese ukugaya okokugcina emishinini kulinganiswa nsuku zonke ngama-laser interferometer. Ukuqedwa okungaphezulu akukona okucatshangelwayo: I-Ra 0.4 µm ijwayelekile ezindaweni zokuvala amavalvu; i-electropolished 316L iyazuza <0.2 µm yamaphampu e-diaphragm ekhemisi. Zonke izinyathelo zibuyela emuva ekusebenzeni kokusebenza-hhayi nje ukuthobelana.
Okwesithathu, ukulawulwa kwekhwalithi okwakhelwe ekuhambeni komsebenzi—okungaboshiwe ekugcineni. Okubalulekile okungenayo kuthola ukuqinisekiswa kwe-spectrographic ngaphambi kokulayishwa. Ukuhlola okungaphakathi kwenqubo kusebenzisa imishini yokulinganisa ehlanganisiwe ehlelwe ngamamodeli e-CAD yekhasimende—hhayi izifanekiso ezijwayelekile. Ukuhlola kokugcina kuhlanganisa ukuhlola okusebenzayo: izindlu zokuhlola ingcindezi ziye ku-1.5× wengcindezi yokusebenza, ukuqinisekiswa kwetorque kumapulagi anentambo, nokuhlola okungena udayi kuwo wonke amajoyinti e-weld abalulekile. Ukulandeleka akuyona inketho—kushumekiwe. Iqoqo ngalinye liphethe umaka onekhodi ye-QR oxhumanisa izitifiketi zezinto ezingavuthiwe, amalogi okuphatha ukushisa, imibiko ye-CMM, nokuphuma ngemvume komsebenzisi. Lapho i-OEM yase-Europe ifuna ukulandeleka okugcwele kwe-ASME BPVC Isigaba VIII ngomjovo wamanzi olwandle, amadokhumenti ayeselungile ngaphambi kokuthululwa kokuqala.
Imikhawulo yomhlaba wangempela ibumba zonke izinqumo. Iklayenti laseNyakatho Melika lalidinga izingxenye zepompo ezingu-120 AMS 5387 emasontweni ayisishiyagalombili—kodwa umklamo wazo wangempela wawudinga ukusetha okuhlanu namahora angu-14 ucezu ngalunye. Ithimba lonjiniyela lika-QIANGSENYUAN liphakamise indawo yesango lokuphonsa elibuyekeziwe futhi lengeza ama-engeli asalungiswa anciphisa ukusetha kube kabili futhi isikhathi somjikelezo sibe amahora angu-6.2—ngaphandle kokudela ingcindezi yokuqhuma. I-winch roller yelinye ikhasimende ihlulekile ngemva kwezinyanga ezingu-18 kunkungu kasawoti ogwini. Ukuhlaziywa kubonise ukuhlasela kwe-intergranular ezindaweni ezithinteke ukushisa kusukela ekushiseni okungafanele kwangemva kokushisela. Isixazululo kwakungezona izindonga eziwugqinsi—besishintshela ku-centrifugally cast F22 chrome-moly enamazinga okupholisa alawulwayo kanye nokuqinisekisa ukumelana nokuzwela ngokuhlolwa kwe-ASTM A262 Practice E.
Lena indlela a imboni ekhethekile yensimbi engagqwali uthola ukwethenjwa: ngokukhuluma ulimi lwezindlela zokwehluleka, hhayi nje ukubekezelelana. Ngokuphatha i-GD&T hhayi njengomhlobiso kodwa njengemephu esebenzayo. Ngokwazi ukuthi kufanele uhlehlise nini umdwebo—nokuthi uzithathe nini izindleko ukuze uhlangabezane newindi lokudiliva eligcina isikhonkwane sisebenza. I-QINGDAO QIANGSENYUAN TECHNOLOGY ayenzi izingxenye. Iletha ukuqiniseka kobukhulu, ukungaguquguquki kwe-metallurgical, nokuthembeka kokusebenza—kushejuli, ngokucaciswa, futhi okulandelekayo kuze kufike eqoqweni elincibilikayo. Konjiniyela ababone "i-stainless" corrode, "nemba" ukukhukhuleka, noma "inkambiso" kuba yigama elifanayo lokuthi ukubambezeleka—lokho kushintsha yonke into.
