Lapho onjiniyela becacisa izingxenye zensimbi ezibekezelela kakhulu amaphampu asebenza ngogesi, amavalvu asendaweni kawoyela, noma amasistimu amawintshi, abadingi nje “ukuphonswa kwensimbi.” Badinga ukuzinza kwe-dimensional ngaphansi kwengcindezi engu-120 MPa. Ubuqotho be-Microstructure ngemva kokwelashwa kokushisa. Ukuqedwa komphezulu okumelana nokuguguleka kwe-cavitation ku-3,600 RPM. Kungakho ama-OEMs omhlaba kanye nabahlinzeki be-Tier-1 bebuyela njalo ku-a Ukunemba kwefekthri yokukhiqiza yokutshala imali akhenge azungeze umthamo-kodwa azungeze ukuziphendulela kwe-metallurgical.
Sibone amaphrojekthi amaningi kakhulu abonakele ngenxa yokulindela okungafani: umdwebo ogxivizwe "±0.05 mm" othunyelwe endaweni esunguliwe ngaphandle kokuqinisekiswa kwe-CMM esizeni; i-cobalt-nickel alloy castings ilethwe ngaphandle kwezitifiketi ze-AMS 5387 zenqwaba; noma izindawo “ezinjengo-cast” ezidinga ukusetshenzwa kabusha ngoba ukubekezelela isikhunta segobolondo bekungaqondani nezindawo zokuvala ezisebenzayo. Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., lawo akuwona amacala—ayisiqalo saso sonke isisho.
Indawo yabo ethobela i-ISO e-Qingdao ayikuphathi ukufakwa kwezimali njengenqubo ezimele. Iyinodi eyodwa kuchungechunge oluhlanganiswe ngokuqinile: isitifiketi sempahla → ukunemba kwephethini ye-wax (±0.15 mm) → isilawuli sokudubula igobolondo le-ceramic (±5°C emijikelezweni engu-1,150°C) → ukuthulula okusizwa ngevacuum → ukukhululeka kwengcindezi yangemva kokusakazwa → ukwenziwa kwe-CNC kwezimbobo ezibucayi nezimbobo ngaphakathi kwe-G0. Awekho ama-handoffs. Ayikho inkontileka engaphansi yenkampani yangaphandle yokwelapha ukushisa noma ukuqedwa kwendawo. Uma indlu yesilinda yephampu ye-piston idinga kokubili u-Rz 0.8 μm wokuqeda ngaphakathi *kanye* kanye* ne-AMS 2700 Yekilasi 1, ithimba elifanayo liyilawula kusukela kumjovo we-wax kuya embikweni wokugcina wokuhlola.
Lokhu kuhlanganiswa okuqondile kuletha izinzuzo ezintathu zekhonkrithi kunezitolo ezivamile zokulingisa:
- Ukubikezela kobukhulu: Izinhlamvu zesihlabathi ziyasuswa eziphasejini zangaphakathi—kuthatha isikhundla sokuhlukahluka okungu-±0.3 mm nokuphindaphindeka okungu-±0.08 mm kuma-valve obubanzi obungu-12-mm
- Ukwethembeka kwe-alloy: Izinto zokusetshenziswa zitholwa kuphela kubahlinzeki abanezitifiketi ze-EN 10204 3.1; ukuncibilika ngakunye kulandeleka ekuhlaziyweni kwe-ladle, imigoqo yokuhlola eqinile, kanye nemephu yokuqina okuncane—hhayi nje “ukuhambisana nezitembu”
- Ukulungela ukusebenza: Umbhobho wengxubevange ye-cobalt awuthunyelwa ngemva kokuhlolwa okubukwayo—uhlolwa i-hydrostatic ngokucindezela kokusebenza okungu-1.5×, ukuhlolwa kokungena kodayi nge-ASTM E165 ngayinye, nokulinganisa ukugeleza ngokumelene namayunithi ayinhloko alinganiswe ku-ISO 5167
Abanye bangase baphikise ngokuthi ukwenza isihlabathi kunikeza izindleko eziphansi zezingxenye ezinkulu. Iqiniso—ezingxenyeni lapho ukubekezelela okungu-±0.5 mm kwamukelekayo futhi ukugoba phezulu ngeke kusheshise ukwehluleka kokukhathala. Kodwa lapho sibuyekeza ukwehluleka kwezinkambu ezingu-47 kuwo wonke ama-valve asebenza ngogesi ngonyaka odlule, u-82% ulandelelwe emuva ekuqineni eduze kwendawo yokuvala noma i-dimensional drift ngemva kokuhamba ngebhayisikili elishisayo—kokubili okugwenywe ngohlaka lokusanhlamvu olucolisekileyo lokutshala imali kanye nokubekezelelana okuqinile njengokusakazwa. Kuma-alloys asekelwe ku-T800 cobalt noma izindlu zokupompa ze-AMS 5387, umbuzo awubizi ngekhilogremu ngayinye. Kubiza ngesigidi samahora okusebenza.
Yini ebeka lokhu Ukunemba kwefekthri yokukhiqiza yokutshala imali ukuhlukana akulona nje ikhono—indlela abashumeka ngayo isahlulelo sobunjiniyela ekucaphuneni. Ngaphambi kokusika i-wax, ithimba labo lihlaba umkhosi izingxabano ze-GD&T: ukubekezelelana kwesikhundla kubize i-flange enezindonga ezincane ezohlanekezela ngesikhathi sokushiswa kwamagobolondo; imfuneko yokuphela kwendawo engahambelani nobulukhuni be-alloy as-cast; noma umjikelezo wokwelashwa kokushisa obeka engcupheni i-sigma phase embrittlement ekuhlanganisweni kwe-cobalt-nickel. Abasho ukuthi "ngeke sikwenze." Abonisa *ukuthi* ungawufeza kanjani umsebenzi—ngezindonga ezincanyana, enye isango, noma izinyathelo zomshini ezixubile ezigcina izici zokuwalungisa ngenkathi ihlangabezana nemininingwane yokuvala.
Kubaphathi bokuthenga abahlola abahlinzeki, nakhu okufanele uqinisekise ngale kwezitifiketi:
- Cela isampula yemibiko ye-CMM—hhayi nje ukuphasisa/izitembu zokwehluleka, kodwa amamephu agcwele okuchezuka e-XYZ abonisa isinxephezelo sokukhula okushisayo sifakiwe
- Idinga imibiko yokuhlolwa kwempahla enamandla angempela esivuno esiqinile—hhayi ubuncane—kanye namaphrofayela obunzima kuzo zonke izingxenye zesigaba
- Qinisekisa ukuvama kokuhlolwa okusekucubunguleni: Ingabe bayakala ubukhulu obubalulekile ngemva kokukhipha i-wax? Ngemva kokudubula igobolondo? Ngemva kokulingisa? Isinyathelo ngasinye sethula ukushintsha okulinganisekayo
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ithumela ama-valve okucindezela imikhumbi ezinkampanini zesevisi yamandla eNyakatho Melika, izisekelo zephampu yensimbi engagqwali kuma-OEM aseJalimane, kanye namarola we-winch center shaft angajwayelekile kuya kubahlanganisi bemishini yasolwandle yaseNingizimu-mpumalanga ye-Asia—bonke banokulandeleka okugcwele kwenkatho, izimiso zokuhlola ezibhaliwe, kanye nezinkumbulo eziyiziro eziboshelwe kumaphutha ahlobene nokusakazwa kusukela ngo-2021. lapho ukwehluleka kungeyona inketho.
Uma iphrojekthi yakho elandelayo idinga okungaphezu kokuthi "insimbi ecijile" -uma idinga i-microstructure engabikezelwa, ukuziphatha okulinganayo okuqinisekisiwe, nokuqhubeka kwe-metallurgical kusuka ku-billet eluhlaza kuya engxenyeni eqediwe-awufuni umthengisi. Ufuna i Ukunemba kwefekthri yokukhiqiza yokutshala imali ephatha konke ukuthululwa njengokuhlola okulawulwayo. Futhi lokho kuqala ngokubuza ukuthi "Ungaphumelela?" kodwa “Nizofakazela kanjani ukuthi iyasebenza—ngaphambi kokuthi iphume esakhiweni?”
