Lapho onjiniyela becacisa a imboni yokukhipha insimbi eyinkimbinkimbi, abaceli nje enye isisekelo. Bafuna umlingani oqondayo ukuthi ukubekezelela okungu-0.02 mm ku-AMS 5387 cobalt alloy pump housing akusona isicelo—kuyisimo esingaxoxiswana sokuphila kwesistimu ngaphansi kwengcindezi ye-hydraulic yamabha angu-400.
Kwa-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., siye sasakaza futhi sasebenza ngomshini amajiyometri ahlukile angaphezu kuka-12,000 amavalvu asebenza ngogesi, izindlu zamasilinda epompo ye-piston, namarola we-winch center shaft—izingxenye lapho ukuhlukaniswa kwesakhiwo esincane noma ukucindezelwa kwensalela kungabangela ukwehluleka kwamahora okusebenza phakathi no-300. Sibone amakhasimende eshintsha abahlinzeki ngemva kokuthi amaqoqo amathathu alandelanayo ehlulekile ukuqinisekiswa kwe-CMM kusixhumi esibonakalayo se-flange. Siphinde sababona benweba izinkontileka ngeminyaka emibili ngemuva kokuthi umlomo wabo wokuqala osuselwa ku-T800 we-cobalt uphumelele ukuhlolwa kokuguguleka kwemijikelezo eyi-15,000 ngaphandle kokukhukhuleka.
Kungani “Inkimbinkimbi” Ingekho Nje Mayelana Nejometri—Imayelana Nokulawulwa Kwensimbi
Ubunkimbinkimbi beqiniso buqala ngaphambi kokuba isikhunta sithelwe. Isisekelo sepompo yensimbi esakhiwe ngesihlabathi singase sibukeke silula—kodwa uma sigxilisa iphampu kawoyela yasogwini engu-2,000 HP, isibalo samanodule e-graphite kufanele sihlale phakathi kuka-120–160/mm², okuqukethwe kwe-pearlite ≥92%, kanye nokwehluka kokuqina kwayo ku-1.2 m baseplate okugcinwe ku-±3 HBW. Lelo zinga lokungaguquguquki lidinga ukuqapha ngesikhathi sangempela sokushisa ngesikhathi sokuqina—hhayi nje ukuhlolwa kwangemva kwenqubo.
Sishumeka ama-thermocouples ngqo emigodini yesikhunta ngokusakazwa okubucayi. Onjiniyela bethu bezinqubo balungisa izinga lokushisa elithelayo, idizayini yokufaka isango, nezinga lokupholisa ngokusekelwe kumaphrofayela okushisa abukhoma—hhayi amashadi amile. Kuma-alloys e-cobalt-nickel afana ne-AMS 5387, sishisisa isikhunta sibe ngu-850°C futhi siyibambe imizuzu engu-90. Ukweqa lesi sinyathelo kubangela i-micro-porosity emingceleni yokusanhlamvu, okuthi kamuva ibe amaphuzu okuqalisa ukuqhekeka ngaphansi kokulayisha okujikelezayo.
Lesi sihloko sichaza ukuthi kungani ukubunjwa kwensimbi yethu kuphumelela ukuphindaphinda okungu-±0.015 mm kumabhoreni abalulekile—hhayi nje ukunemba—nokuthi kungani ukulingwa kwethu kwensimbi engagqwali kugcina i-Ra ≤0.8 µm njenge-cast endaweni yokuvala, esusa ukugaya kwesibili ngama-oda angu-68%.
Ukuhlanganisa Okuqondile Okuletha Ukuzinza Kwe-Dimensional
Izitolo eziningi "zokuma okukodwa" zikhipha ukwelashwa kokushisa noma ukuqeda. Lokho kudala izikhala ze-handoff: i-casting iphola ngokulinganayo ngemva kokucisha, bese i-warps ngesikhathi sokulungiswa kwe-CNC. Silawula zonke izigaba—kusuka erisidi yempahla engavuthiwe ukuya ekuhlolweni kokugcina kokusebenza—endaweni eyodwa enesitifiketi se-ISO.
- Iyasakaza: Ukutshala imali kumabhomu e-cobalt anezindonga ezincane; ukukhishwa kwesihlabathi esiboshwe nge-resin kwezisekelo ezinkulu zephampu yensimbi ezifika ku-1,800 kg
- Ukwenza imishini: I-5-axis CNC enenqubo yokuhlola ukuqondanisa kwezindawo eziningi (isb., ukufanisa i-axis ye-bore nobuso obukhuphukayo phakathi kokufunda okuphelele okungu-0.008 mm)
- Ukwelashwa kokushisa: I-vacuum annealing ye-T800 alloys; ukuqina komkhathi olawulwayo kokulingisa okungenasici kwe-martensitic
- Ukuqeda: Electropolishing for corrosion resistance; udubule ukuchama ukuze uthole isandiso sempilo yokukhathala kuma-winch shafts
Lapho ikhasimende laseYurophu lidinga indlu yesilinda yephampu ye-piston engajwayelekile enamashaneli okupholisa angaphakathi namazinyo egiye langaphandle, saqalisa ukulingisa, sabe sesiqinisekiswa ukusatshalaliswa kokuqina kodonga ngokuskena kwe-CT—hhayi nje ukuhlola nge-ultrasonic. Kungaleso sikhathi kuphela lapho saqinisa khona ingxenye yomshini. Umphumela? Ukwamukelwa kwesihloko sokuqala ekucwaningweni kwe-OEM kwe-Tier-1. Akukho ukusebenza kabusha. Akukho ukubambezeleka.
Ikhwalithi Eyakhelwe Ngaphakathi-Ayihloliwe
Asilindi ukuhlolwa kokugcina ukuze sibambe izinkinga. Iqoqo ngalinye liphethe ukulandeleka okugcwele: inombolo yokushisa, umbiko wokuhlaziywa kwencibilika, i-ID yenkatho yokusakaza, inguqulo yohlelo lwe-CNC, i-ID yomsebenzisi, namalogi okuhlola e-CMM—konke kuxhunywe ngedijithali. Uma i-valve yokucindezela ihluleka ukuhlolwa kwe-hydrostatic, sidonsa ukushisa okufanayo okufanayo kwento esetshenziswa ekubumbeni, siphinde siqalise ukuhlola okuqinile, futhi siqhathanise izithombe ze-microstructure side-by-side nenkatho eyamukelwe ngaphambilini.
Ukuhlola kwethu okungenayo akusona isheke lebhokisi. Kuma-alloys e-cobalt, siqinisekisa ukuthobela kwe-AMS 5387 sisebenzisa i-OES spectroscopy—hhayi nje izitifiketi zokugaya. Sihlola usayizi wokusanhlamvu nge-ASTM E112 ngayinye kukho konke ukusakaza kwesithathu. Senza ukuhlola kokungena kodayi kuzo zonke izindawo zokuvala ezingomshini—ngisho nalapho kungashiwongo—ngoba ulwazi lubonisa u-22% wamaphutha agqagqene avela kuphela ngemva kokukhululeka kokugcina komshini.
Lokhu kuqina kuletha imiphumela elinganisekayo: 99.4% isivuno sokuqala sokudlula ezingxenyeni ze-cobalt alloy; I-zero field returns ngokungahambisani ne-dimensional ngo-2023; kanye nesikhathi sokuhola esimaphakathi sezinsuku eziyi-18 sokulingisa i-prototype—sehle sisuka ezinsukwini ezingama-32 umkhakha wonke.
Ukubambisana Kwangempela Kuqala Ngaphambi Kokuba Umdwebo Uphothulwe
“Ungakwenza lokhu?” umbuzo wokuqala ongalungile. Okulungile uthi: “Kwenzekani uma sehlisa lolu gqinsi lombambo ngo-1.2 mm?” Senza izibuyekezo zokwenziwa—hhayi njengabalindisango, kodwa njengabahlanganyeli. Sihlaba umkhosi ukungqubuzana kwe-GD&T kusenesikhathi: ukubekezelela isikhundla esibiza u-±0.01 mm endaweni engu-200 mm ububanzi, kuyilapho ukubekezelela kokusakaza kwesisekelo kungu-±0.3 mm. Siphakamisa enye indlela yokwenza idatha noma ama-engeli asalungiswa abuyekeziwe alondoloza umsebenzi kodwa anciphise izindleko ngo-27%.
Sisekela amakhasimende aseNyakatho Melika, aseYurophu, naseNingizimu-mpumalanga Asia ngengxoxo eqondile yobunjiniyela—hhayi ngezingqimba zokuhumusha. Lapho umkhiqizi wephampu waseJalimane edizayina kabusha i-valve yawo ukuze kwehliswe isisindo, siphakamise ukushintsha kusuka kokungu-316 kokusakaza okungenasici kuya ku-duplex 2205—isilinganiso sokugqwala esifanayo, amandla okukhiqiza aphezulu angu-22%, futhi asikho isidingo sokwelashwa kokushisa kwangemva kokushisela. Bakwamukela. I-oda labo elilandelayo laphindeka kabili.
Uma isicelo sakho sidinga imboni yokukhipha insimbi eyinkimbinkimbi amandla—hhayi nje umthamo—udinga isiyalo se-metallurgical, ukulawulwa kwenqubo edidiyelwe, kanye nokungabekezeleli lutho kokuqagela. Udinga ozakwethu abaphatha konke ukulingisa njengokuthi kubambe amabha angu-400 wamandla asebenza ngogesi—noma abagcina uketshezi lokumba ogwini oluqukethwe ekujuleni kwamamitha angu-3,000. Lokho izinga esakhela kulo. Nsuku zonke.
