Xa impompo ye-hydraulic isilela phantsi koxinzelelo lwe-350-bar, okanye i-cobalt-alloy nozzle iqhekeka emva kweeyure ezingama-800 zenkonzo yerhasi emuncu, iinjineli azibuzi ukuba "Ngubani owenze le nto?" Bayabuza: "Ngubani onokuyilungisa-kwaye aqinisekise ukuba ayisayi kuphinda yenzeke?" Lo mbuzo wohlula ababoneleli ngempahla kumaqabane okwenene. Embindini walo mahluko kukho isakhono esinye: ukuchaneka okungaguquguqukiyo, okuphindaphindwayo kwimisebenzi yefektri yealloyi ekhethekileyo-apho i-metallurgy, ijometri, kunye nomsebenzi obalulekileyo wobuthunywa zidibana.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. iphatha ezo ntsilelo—kungekhona njengeziphene eziza kulungiswa, kodwa njengeengongoma zedatha yokucokisa ulawulo lwenkqubo. Siye sabona i-AMS 5387 i-cobalt alloy pump housings i-warp ngexesha lonyango lokushisa xa amazinga okupholisa adlula i-12 ° C / min. Silinganise i-T800-based based shaft rollers ilahlekelwa yi-0.018 mm ukujikeleza emva kwemijikelo ye-torque eyi-15,000-kuphela ngenxa yokuba i-original casting grain flow ayizange ihambelane nevector yomthwalo. Le ayiyomida yethiyori. Ziyimibundu ejongwayo ebaleni ebumba lonke uphononongo lomzobo, isicwangciso ngasinye sendlela yesixhobo, yonke indawo yokuhlola.
Izakhono ezine ziqinisekisa ukuthembeka kwazo-hayi njengamabango okuthengisa, kodwa njengeziphumo ezinokulinganiswa:
- Ubuchule beCobalt-nickel ngaphaya kweedatadata. I-AMS 5387 ayisiyiyo nje “i-resistant-resistant.” Ukusasazwa kwayo kwe-carbide utshintsho kunye nembali ye-thermal. I-Foundry yabo ilawula izinga lokuqiniswa ngaphakathi kwe-± 0.8 ° C / isekhondi; iiseli zabo ze-CNC zisebenzisa izixhobo ezipholileyo ze-cryo ukubamba ingqibelelo yomphezulu ngaphantsi kwe-Ra 0.4 µm kwiibhore ezigqityiweyo. Yiyo indlela abahambisa ngayo iiplagi ze-cobalt alloy ezitywinwa kwi-420 ° C ngaphandle kwe-galling-kwaye kutheni abathengi baseNorth Sea oilfields bazicacisela iziqu zevalve ye-subsea.
- Udibaniso oluthe nkqo oluthintela ukukhukuliseka kwe-dimensional. Uninzi lwababoneleli abakhuphela ngaphandle, ukwenza oomatshini, kunye nokugqiba kubathengisi abathathu abahlukeneyo. Isandla ngasinye songeza ukunyamezelana. I-QINGDAO QIANGSENYUAN yenza ukugalela isanti, i-5-axis milling, unyango lobushushu oludambisa uxinzelelo, kunye ne-electropolishing kwenye indawo eqinisekisiweyo ye-ISO. Indlu yesilinda yempompo yepiston isuka kwintsimbi ekrwada ukuya kungqinisiso lokugqibela lwe-CMM kwiiyure ezingama-72-akukho mpahla yangaphandle, akukho mahluko wezinto ze-batch-to-batch. Ukulandeleka akulogwanga; Ifakwe i-laser kuyo yonke indawo.
- Ukuqinisekiswa koyilo olusebenzayo-hayi nje ukuthotyelwa kwe-GD&T. Abathengi bathumela imizobo. Iinjineli ziphendula ngolu hlobo: “Le chamfer eyi-0.05 mm ibamba inkunkuma kwiindledlana zolwelo ezinokukhanya okuphezulu—itshintshe nge-0.2 mm radius.” Okanye: "Ubukhulu bodonga lwangoku budala ukugqithelana kwe-resonant frequency kwi-1,850 rpm. Yongeza i-ribbing apha." Oku akugxeki. I-co-engineering esekwe kwiminyaka eli-12 yohlalutyo lokungaphumeleli kuyo yonke i-hydraulic, impompo, kunye neenkqubo ze-winch.
Abanye baphikisa ngelithi umsebenzi okhethekileyo wealloy ufuna ukusondela kwengingqi-“Ufuna iinjineli kwindawo ukuze uhlengahlengise ukutya ngexesha lokwenyani.” Kodwa uhlengahlengiso lwexesha lokwenyani lwenzeka ngaphambi kokuba kuqale ukusika. Iimodeli zabo zangaphambi kokwenziwa kweemodeli zesoftware yokwenziwa kwetshiphu kwingxubevange ye-T800 kwii-engile zeerake ezahlukeneyo, ukuqikelela ukunxitywa kwesixhobo ngaphakathi kwe-3% yobomi bokwenyani. Xa umthengi waseYurophu efuna i-220 non-standard pressure valves kwiiveki ze-11, i-bottleneck yayingekho umthamo-yayiqinisekisa i-microstructure homogeneity kwii-castings ezili-16. Isicombululo sabo? Ilebhu ye-metallografi kwisiza + imephu ye-EDS ezenzekelayo. Iqashiso ngalinye lipasile i-ASTM E112 yokuqinisekisa ubungakanani beenkozo ngaphambi kokuba kuqale ukusebenza ngoomatshini.
Olu qeqesho lulinganisa—kodwa kuphela apho izinto ezibalulekileyo zihlala zilungisiwe. Abaleqi umthamo. Balungiselela ukuphinda-phinda: umqhubi ofanayo, umatshini ofanayo, ugxininiso olufanayo lokupholisa, umjikelo ofanayo wokucoca emva kwenkqubo. Kungenxa yoko le nto imveliso yabo yentsimbi iphumelela iyahambelana amandla okuqina e-780 MPa ± 12 MPa—hayi “ukuya kuthi ga kwi-780 MPa.” Kutheni iziseko zabo zempompo zensimbi engenasici zibambe ukuthambeka ngaphakathi kwe-0.03 mm ngaphezulu kwe-600 mm-iqinisekiswe yi-laser tracker, hayi nje i-CMM. Kutheni imilomo yabo ye-cobalt alloy iphila kwimijikelo ye-14,000 ye-thermal kwi-injini yokubuyisela ubushushu ngaphandle kwe-microcracking.
Umzi-mveliso okhethekileyo wamacandelo engxubevange ufumana ukuthenjwa kungekhona ngokuthembisa ukugqibelela—kodwa ngokubhala kanye apho ukungafezeki kuhleli khona, emva koko ubunjineli obukungqongileyo. I-QINGDAO QIANGSENYUAN TECHNOLOGY ayifihli ukuguquguquka. Bayenza imephu: i-thermal gradients ekubunjweni kokubumba, izixhobo zokuphambuka kwi-deflection vectors kwi-deep-pocket milling, amazinga e-hydrogen pickup ngexesha le-electropolishing. Iingxelo zabo ezisemgangathweni azibhalisi ukudlula / ukungaphumeleli. Babonisa amaxabiso edelta xa kuthelekiswa neegophe ezisisiseko-ukuze abathengi babone kungekuphela nje *ukuba* inxalenye iyadibana, kodwa *ungakanani umda oseleyo* phambi komda wokusebenza.
Ikamva alikho malunga noomatshini abakhulu okanye ii-spindles ezikhawulezayo. Imalunga neelophu zempendulo ezingqongqo phakathi kokusebenza kwentsimi kunye neeparamitha zenkqubo. Ngoku, iqela labo le-R&D linxibelelanisa utyikityo lokungcangcazela olusuka kwiziko elisetyenzisiweyo leshaft rollers ezineemephu zoxinzelelo olushiyekileyo olusuka kwizikena zabo ze-XRD. Kunyaka olandelayo, loo datha iya kuqhuba imveliso yendlela yesixhobo elungelelanisiweyo-ukusebenza hayi kwimilinganiselo yegama, kodwa kuqikelelo lweeprofayili zokuguqulwa komthwalo wenkonzo. Kulapho ukuthembeka kuyeka ukuba yinto ekujoliswe kuyo-kwaye ibe yimveliso enokulinganiswa.
