Xa iinjineli zichaza a umzi-mveliso wamalungu okujula kwi-mission-critical valves hydraulic valves okanye i-high-wear-winch shafts, abathengi nje isinyithi-bathenga ukuzinza kwe-dimensional phantsi kwe-350-bar yoxinzelelo, ukunyaniseka kwe-microstructure emva konyango lobushushu, kunye nokulandelwa kwebhetshi epheleleyo ukuya kwinani elinyibilikayo. Yiyo loo nto amaqela oyilo kuMntla Merika naseYurophu esiya ngokuya ehambisa izinto ezintsonkothileyo zempompo ye-cobalt-alloy ukuya eQingdao-kungekhona ngexabiso eliphantsi, kodwa ngokuziphatha okuqikelelweyo kwesinyithi kunye nokuhanjiswa okumangalisayo.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza apho unyamezelo lokuphosa ludibana nokusebenza okusebenzayo: ±0.05 mm kwizindlu zempompo zepiston, ukuthotyelwa kwe-AMS 5387 kuqinisekisiwe ngohlalutyo lobungakanani beenkozo ze-ASTM E112, kunye nokugqitywa komphezulu okubanjwe ku-Ra 0.8 µm kubuso bokutywinwa kwe-cobalt-nozzle. Siye sabona abathengi betshintsha ababoneleli emva kweebhetshi ezintathu ezingaphumeleliyo zeeplagi ze-T800 ze-alloy-ixesha ngalinye, ingcambu ibangela ukulandelwa kwe-carbide engahambelaniyo ngexesha lokuqina. I-Qiangsenyuan iyakunqanda oku ngokulawula zombini ukungeneka kokungunda kwesanti *kunye* kunye* nesisombululo sasemva kokuphoswa kwereyiphu yeendlela zokuvala ngaphakathi endlwini. Akukho handoff. Akukho ngqikelelo.
Ukudityaniswa kwabo ngokuthe nkqo akulolwimi lokuthengisa-yinkqubo eyimfuneko. Thatha i-winch yemoto ye-winch i-shaft roller: i-cast in ductile iron (ASTM A), i-rough-machined kwi-5-axis DMG Mori, iphathwa ngobushushu ukuya kwi-28-32 HRC, emva koko igqibe umhlaba kunye ne-in-process ye-CMM impendulo. Inyathelo ngalinye lihlala phantsi kophahla olunye. Oko kuphelisa idimensional drift eqhelekileyo xa iivenkile zithumela izithuba ezingenanto kwiivenkile zoomatshini zangaphandle-ingakumbi ibaluleke kakhulu xa ithwele iijenali ifuna ukuphuma ngaphantsi kwe-0.015 mm. Abathengi banika ingxelo nge-40% embalwa yokukhatywa kwenqaku lokuqala xa kuthelekiswa neemodeli zangaphambili zokufumana amanqaku amaninzi.
Ingqeqesho yezinto eziphathekayo ayixoxisi apha. I-cobalt-nickel ingots eluhlaza ifika kunye neengxelo zokuvavanya i-mill ebonisa i-carbon ≤0.12%, i-chromium 27-31%, kunye ne-cobalt ≥60%-iqinisekisiwe ngaphambi kokunyibilika. Xa impompo ye-OEM yaseYurophu ifuna ulawulo olungqongqo kumxholo we-delta ferrite kwi-castings yensimbi engenasici, i-Qiangsenyuan ayizange ilungelelanise i-chemistry; bafakela i-spectrometer ye-PMI ephathwayo kwisikhululo sokugalela kwaye bafaka yonke into eyenziweyo ngokuchasene neegophe zokupholisa. Loo nqanaba lolawulo lwegranular lichaza ukuba kutheni i-AMS yabo ye-5387 components idlula ngokuqhubekayo i-NDT Level III yokuhlolwa kwe-ultrasonic-akukho kuphinda kusebenze, akukho nkunkuma.
Ukuhanjiswa kwehlabathi lokwenyani kuxhomekeke kulungelelwaniso lobunjineli-kungekhona nje umthamo wemveliso. Ngethuba lokuphononongwa kwe-GD & T yomzobo wezindlu zevalve yoxinzelelo, iqela labo libonise ukunyamezela kweprofayili ye-0.02 mm kwi-flange engasebenziyo. "Singayibamba," batsho, "kodwa yongeza i-17% yexesha lomatshini kunye nenzuzo yokusebenza." Bacebise ukuyiphumza ibe yi-0.1 mm, iqinisekise utshintsho kunye neemephu zokusasazwa koxinzelelo lwe-FEA, kunye nokwabelana ngokulinganisa ukwanda kwe-thermal ebonisa ukuba akukho mpembelelo kwintembeko yetywina. Olo hlobo lwentsebenziswano yokusombulula iingxaki-esekelwe kwi-physics, kungekhona izithembiso zokuthengisa-yinto eguqula i-odolo enye ibe yintsebenziswano yeminyaka emininzi. Kumaqela adinga izisombululo ezichanekileyo zokuphosa isinyithi eziziphatha njengoko kuqikelelwe, kungekhona njengoko kuthenjiweyo, umendo uqala ngokuphononongwa kobugcisa-kungekhona isicelo sokucaphula.
