Lapho onjiniyela becacisa a imboni yenkampani yokuphonsa i-wax elahlekile, azigcini nje ngoku-oda izingxenye zensimbi—zivikela ukuqina kohlangothi ngaphansi kwengcindezi ye-hydraulic yamabha angu-300, ubuqotho be-microstructure ngemva kokuhamba ngebhayisikili, kanye nokuqedwa kwendawo okungeke kubambe udaka olubi kuma-pump manifolds. Lokho kuyiqiniso lokusebenza ngemuva kokutshala izimali ngokunemba—hhayi indawo yokusebenzela enamaphethini we-wax namagobolondo e-ceramic, kodwa iketango lenqubo yensimbi elawulwa ngokuqinile lapho ukuchezuka okukodwa kogqinsi lwegobolondo noma izinga lerempu yokukhipha iwaxi kungalahla ingxubevange ye-cobalt engu-$4,200 ngaphambi kokuqala komshini.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza lolo hlobo lwesikhungo-e-Qingdao, e-China-lapho ukukhishwa kwe-wax elahlekile kungahlukanisiwe nemishini ye-CNC noma isitifiketi sempahla. Ishumekiwe. Sibone amakhasimende ethumela imidwebo ye-GD&T-valve esindayo elindele izingcaphuno ezisheshayo. Esikhundleni salokho, ithimba lethu lihlabe umkhosi ngezinkinga ezimbili ezibucayi: okokuqala, i-callout ye-0.015 mm flatness endaweni yokuvala engu-280 mm iphikisana nephrofayela ye-AMS 5387 yokuhlanekezela; okwesibili, ingxubevange esekelwe ku-T800 esekelwe ku-cobalt idinga ukwelashwa kwangaphambili kokushisa ngaphambi kokuphenduka okungalungile ukuze kugwenywe ukuqhekeka okuncane kubhore. Alukho udaba oluvele kumodeli ye-CAD-kodwa zombili bekuzophazamisa ukuhlolwa kokusebenza. Yingakho iqiniso imboni yenkampani yokuphonsa i-wax elahlekile kumele ifunde phakathi kwemigqa yomdwebo, hhayi nje ubukhulu bawo.
Abahlinzeki abaningi bahlukanisa ukusakaza nokuqeda. I-QINGDAO QIANGSENYUAN ayifuni. Isikhungo sabo esithobela i-ISO sisebenza ngokusakazwa kwe-investimenti eceleni komshini we-CNC we-5-axis, ukuhlanza ukushisa kwe-vacuum, kanye ne-passivation noma i-HVOF enamathelayo-konke ngaphansi kophahla olulodwa. Lokhu kuhlanganiswa okuqondile kubalulekile lapho ukhiqiza izindlu zesilinda sephampu ye-piston zokusetshenziswa kukawoyela negesi yasolwandle. Ukulingwa kwesihlabathi kungase kuphathe ijiyomethri yenqwaba, kodwa ukufakwa kwe-investimenti kuphela okuletha ukuguquguquka kodonga okungu-0.02 mm okudingekayo ezindleleni zamanzi ezinomfutho ophezulu. Futhi imishini ebekwe endaweni eyodwa kuphela eqinisekisa ukuthi ukugxila okungu-0.008 mm phakathi kwe-bore kanye ne-flange ekhuphukayo kuhlala kunjalo ngemva kokukhululeka kwengcindezi. Silandelele imigqa yesikhathi yokulethwa kuwo wonke ama-oda esibonelo angu-47: ukugeleza komsebenzi okuhlanganisiwe kunciphisa isikhathi sokuhola esimaphakathi ngezinsuku ezingu-22 uma kuqhathaniswa nokukhipha umsebenzi kanye nokwenza imishini ngokuhlukana. Ibhodlela bekungelona umthamo-bekuwumbhalo we-handoff, ukuxhumanisa ukuhleleka kwesistimu, kanye nokuphinda kuhlolwe kabusha.
Isiyalo esibalulekile sihlukanisa ozakwethu abathembekile kubathatha ama-oda. Imithombo ye-QINGDAO QIANGSENYUAN eqinisekisiwe yezinhlamvu ze-AMS 5387 cobalt alloy enemibiko egcwele yokuhlolwa komshini—futhi ihlola wonke amaqoqo ngokuqhathanisa nosayizi wokusanhlamvu we-ASTM E112 kanye namazinga okufakwa e-ASTM E1268 kusetshenziswa imakroskopu yangaphakathi yasendlini. Lapho ikhasimende licela amapulagi angajwayelekile e-T800 alloy amasistimu ewintshi angaphansi kwe-subsea, ithimba alizange limane liqalise iphethini. Baqinisekise ama-coefficients okunweba okushisayo ngokumelene nendlu yensimbi engagqwali yokukhwelana, isango elilungisiwe ukuze kuncishiswe ukuncipha kokuqina okuqondile esiteshini sokugeleza sobubanzi obungu-12 mm, futhi basebenzise izivivinyo ezintathu ngaphambi kokukhulula ithuluzi. Lelo zinga lokulawula lichaza ukuthi kungani imibhobho ye-cobalt alloy yabo ifinyelela ngokuqhubekayo > amahora angu-10,000 okusebenza kuketshezi olugcwele isihlabathi olunesivinini esikhulu—ngaphandle kokuchezuka kokugeleza okubangelwa ukuguguleka.
Uma uhlola a imboni yenkampani yokuphonsa i-wax elahlekile, buza imibuzo emithathu: Ingabe bangakwazi ukubamba ±0.01 mm kubukhulu obungu-150 mm ku-AMS 5387 ngaphandle kokugaya okuthunyelwe? Ingabe agcina ukulandeleka okugcwele kusukela kunombolo yokushisa yezinto ezingavuthiwe ukuya embikweni wokugcina we-CMM? Futhi ingabe bayahlaba umkhosi izingozi zokwenziwa ngesikhathi sokubuyekezwa konjiniyela—hhayi ngemva kokuba isihloko sokuqala sehlulekile ukuhlolwa kwengcindezi? U-QINGDAO QIANGSENYUAN uphendula ngoyebo kubo bobathathu. Amandla abo awekho ekubeni nawo wonke umshini—kusekwazini ukuthi yisiphi isinyathelo senqubo *okufanele* silawulwe, yikuphi okuguquguqukayo *okumele* kulinganiswe, futhi lapho ukwahlulela komuntu kweqa okuzenzakalelayo. Njengoba isidingo somhlaba wonke sikhula semibhobho yepompo ebaluleke kakhulu emishini kanye namavalvu okulawula ama-hydraulic, umehluko wangempela awusona isikali. Kuyikhono lokuphatha konke ukulingisa sengathi kungena ku-valve yokuphepha ye-downhole-ngoba ngezinye izikhathi, kunjalo.
