Lapho ipompo ye-hydraulic yehluleka ngaphansi kwengcindezi yamabha angu-350—noma umbhobho we-cobalt alloy uguguleka ngemva kwamahora angu-42 kuphela enkonzweni yegesi emuncu—umsuka awuvamile ukuklama. Ubuqotho bezinto ezibonakalayo. Ukuzinza kwe-microstructure. Iwuchungechunge olunganqamuki olusuka kusitoko esingavuthiwe esiqinisekisiwe ukuya ekuhlolweni kokugcina okuthobela i-GD&T. Lolo chungechunge luqala ku- imboni ekhethekile ye-alloy insert.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza enye yezindawo zokukhiqiza zase-China ezilawulwa ngokuqinile kakhulu zokufakwa kwe-alloy okusebenza kahle kakhulu—hhayi njengendawo yokusungula ejwayelekile, kodwa njengozakwethu wengxenye esebenzayo. Sibone amakhasimende enqaba amaqoqo amathathu alandelanayo ezindlu zamaphampu ze-AMS 5387 ngenxa yokuthi ukuhlukaniswa kwe-carbide yomngcele wokusanhlamvu akuzange kubonwe ngesikhathi sokwelashwa kokushisa. Sibuke onjiniyela belungisa kabusha amarola e-T800 esikhungweni se-shaft kabili—okokuqala ngenxa yokuqina kobuso obungaphandle kwe-spec, kwase kuba i-porosity engaphansi komhlaba ephuthelwe ekuhlolweni kwe-ultrasonic. Lezi akuzona izingozi zethiyori. Ziyizindlela zokwehluleka eziphindaphindwayo—futhi ziyanyamalala kuphela lapho kukhiqizwa, kwenziwa imishini, nokuqinisekiswa kwensimbi kuhlala ngaphansi kophahla olulodwa.
Abahlinzeki abaningi baphatha ama-alloys e-cobalt-nickel njengezinkinga “ezinzima emshinini”. I-QINGDAO QIANGSENYUAN iwaphatha njengezinhlelo. Yonke ingxenye ye-AMS 5387 noma i-T800 iqala ngento eluhlaza eqinisekiswe kabili—okulandeleka enombolweni yokushisa yesigayo, kuqinisekiswe ibhalansi ye-Co/Ni/Cr/Mo *ngaphambi* kokuncibilika. Alikho iqoqo elingena esithandweni ngaphandle kokuhlaziywa kwe-spectral okuqinisekisa ukubekezelela okungu-±0.15% ezintweni ezibalulekile. Esikhungweni sethu esithobela i-ISO, ukutshala imali akulandelwa umshini we-CNC—kuhlanganisiwe: isikhunta samagobolondo esiklanyelwe isabelo esincane sesitoko, izinto zokulungisa imishini ezakhiwe kusuka endaweni ephonsiwe yedatha, imijikelezo yokwelashwa kokushisa ekhiyelwe kumazinga athile okupholisa *ngemuva* kokufakwa kokugcina. Sibamba kanjalo ±0.015 mm kumasilinda wephampu yepiston engu-320-mm-diameter—ngisho nogqinsi lwezindonga oluwu-6.2 mm namashaneli okupholisa angaphakathi.
Ukuhlanganiswa okuqondile kuletha okungaphezu kokulawula kobukhulu. Ivimbela ukuyekethisa okufihliwe okubulala ukusebenza. Isibonelo: izisekelo ze-sand-cast iron ngokuvamile zidinga ukukhululeka kokucindezeleka kwangemva kokwelashwa-kodwa uma umshini ngaphambi kokukhulula, izingcindezi ezisele zisonta i-flange ekhuphukayo. Sikwenza ngokulandelana: phonsa → ukudambisa ingcindezi → umshini omangelengele → ubudala → umshini wokuqeda → qinisekisa i-CMM. Umqondo ofanayo uyasebenza kumabhobho e-cobalt alloy. Asilokothi sisebenzise ukunamathela kwe-HVOF ngaphambi kokugaya i-ID yokugcina; ukungezwani kokunwebeka okushisayo kudala imifantu emincane engabonakali ukudaya okungena ngaphakathi kodwa kube yinhlekelele ngaphansi kokushaqeka okushisayo okujikelezayo. Ishidi lethu lenqubo lamapulaki e-AMS 5387 lihlanganisa amaphuzu ayisikhombisa ayisibopho—ngalinye lidinga ukusayinwa yi-metallurgist, hhayi nje umhloli we-QC.
Ukwethembeka komhlaba wangempela kuvela ekuqondisweni okubhaliwe—hhayi ezimangalweni zokumaketha. Wonke amavalvu okucindezela ahamba ngokulandeleka okugcwele: izitifiketi zezinto ezibonakalayo, amalogi okwelapha ukushisa, imibiko ye-CMM ebonisa amaphuzu okulinganisa angu-127 ingxenye ngayinye, nokuqinisekiswa kokuqedwa kwendawo kusetshenziswa kokubili i-profilometry ne-optical interferometry. Asigcini nje ngokuhlangabezana nokubekezelelwa kwe-ISO 2768-mK—sibhala *indlela* ukubekezelela ngakunye kwafinyelelwa: kungakhathaliseki ukuthi nge-5-axis ngesikhathi esisodwa sokugaya, ukupholisha nge-electrochemical, noma ukuqedwa komgqomo we-centrifugal. Lapho i-OEM yaseYurophu ifuna ubufakazi bokufana kwe-microstructure kuwo wonke umgodi wewintshi wewintshi wamamitha angu-1.2 ubude, silethe izithombe ze-SEM ezinezigaba—hhayi nje isitembu “esivumelana ne-ASTM E112”. Lowo umehluko phakathi kokuphasa ukuhlola nokuzuza ukwethenjwa konjiniyela.
Uma ubheka phambili, isidingo sokufakwa kwe-alloy okubalulekile ngeke sehle—sizolola. Imithetho eqinile yokukhipha umoya iphusha amaphampu kawoyela negesi kungcindezi ephezulu. Izimoto zokwakha ezisebenza ngogesi zidinga izingxenye zewintshi ezilula neziqinile. Ama-turbines omoya angasogwini adinga imizimba yama-valve amelana nokubola ephila iminyaka engu-25 ngaphandle kokushintshwa. Ukufeza lezo zidingo kusho ukujula ezinqubweni eziyingxubevange: ukuhlanganisa ukufakwa kwe-investimenti eseduze ne-net-shape nokunemba kwe-EDM yezimbobo zokupholisa ezincane kuno-0.3 mm, noma ukuhlanganisa i-laser cladding ngqo ekusebenzeni kwe-CNC kokumelana nokuguga kwendawo. Ukuvela okulandelayo kwe- imboni ekhethekile ye-alloy insert ayiyona imishini emikhulu—kunezimpendulo eziqinile phakathi kwedatha yokuhluleka kwenkundla, ukumodela kwensimbi, kanye nokulungiswa kwenqubo yesikhathi sangempela. I-QINGDAO QIANGSENYUAN yakha leyo loop manje—ingxenye eyodwa ye-AMS 5387, ijometri eyodwa ye-T800, imakron eyodwa eqinisekisiwe ngesikhathi.
