Xa iinkqubo ze-hydraulic zingaphumeleli phantsi koxinzelelo lwe-350-bar, xa izindlu zempompo ziqhekeka emva kweeyure ze-12,000 zokusebenza, okanye xa i-cobalt-nickel nozzles ikhupha ngokukhawuleza kunokuba kulindelwe-iinjineli azigxeki ukuyila. Bayilandelela emva kwisigqibo esinye: imfezeko yezinto eziphathekayo ezidityaniswe nokunyaniseka komgangatho kwi nickel-based alloy mechanical parts.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. uye wachitha ngaphezu kweshumi leminyaka ecombulula kanye loo ngxaki—kungekhona kwingcamango, kodwa kumgangatho weevenkile. Siye sabona i-AMS 5387 iphosa i-warp ngexesha lonyango lobushushu ngenxa yesakhiwo esingahambelaniyo senkozo. Siye saphinda saphinda sasebenza iirola ze-T800 ze-alloy centre shaft izihlandlo ezithathu ngenxa yeentanda ezincinci ezifihlwe ngaphantsi komphezulu. Ezi ayizontelekelelo. Zizifundo zentsimi eziye zayila indlela esisebenza ngayo, ukuphosa, kunye nokuqinisekisa yonke indawo.
Kutheni i-alloys esekwe kwi-nickel ifuna ngaphezulu kwesakhono se-CNC
I-alloys esekelwe kwi-nickel efana ne-Inconel 718, i-Hastelloy C-276, kunye ne-AMS 5387 ixhathisa ukubola kwaye igcina amandla angaphezu kwe-650 ° C-kodwa iphinda isebenze ngokukhawuleza, iqhuba ukushisa kakubi, kwaye inxiba izixhobo zokusika ngokukhawuleza. Ivenkile esemgangathweni ye-CNC ayinakubamba ukunyamezela kwe-± 0.01 mm kwi-420-mm-diameter piston pump cylinder yezindlu ezenziwe kwi-T800 alloy ngaphandle kwezicwangciso ezizinikezelweyo ze-toolpath, imijikelezo yokuqina kwe-thermal, kunye ne-process metrology.
Yiyo loo nto ukudibanisa ngokuthe nkqo kubalulekile. Kwiziko lethu le-Qingdao, ukuphosa akukhutshelwa ngaphandle. Ukugalelwa kwesanti kunye notyalo-mali lwenzeka phantsi kophahla olunye-kufutshane namaziko omatshini amaninzi alungelelaniswa yonke imihla. Silawula ubushushu be-mold preheat, isantya sokuqina, kunye noxinzelelo lwasemva kokuphosa ngaphambi kokusikwa kokuqala. Akukho handoffs. Akukho mahluko kwibhetshi ukuya kwibhetshi kwisithuba sedendritic. I-microstructure nje ephindaphindwayo-kwaye kulapho uzinzo lwe-dimensional luqala khona.
Sivavanya oku mihla le: umthengi ucele iiplagi ze-cobalt ezifanayo ezili-18 zoxinzelelo oluphezulu lwe-fuel manifolds. I-Batch 1 iphumelele ukuhlolwa kwe-CMM kodwa yasilela uvavanyo lokuqhuma kwi-412 bar. I-Micro-CT ibonakalise i-porosity efihlakeleyo kufuphi negxalaba lokutywina-ingabonakali ngokugawula umphezulu. Sihlengahlengise uyilo lokungena, sathoba iqondo lobushushu nge-23 ° C, kwaye songeza ukungcangcazela kwe-ultrasonic ngexesha lokuqina. Iqela lesi-2 libambe 487 ibha. Elo nqanaba lolawulo libakho kuphela xa iinjineli ezisakhayo kunye noomatshini zihlala kunye ngexesha lophononongo lwe-DFMA.
"Ukuchaneka" kuthetha ntoni ngenene kwizinto ezibaluleke kakhulu kubuthunywa
Ukuchaneka akukona nje ukunyamezelana okuqinileyo. Kukulungelelaniswa okusebenzayo phakathi kwejometri, isinyithi, kunye nemeko yenkonzo. Umzimba wevalve yoxinzelelo kufuneka utywine-kodwa kufuneka uphile kwibhayisekile eshushu ngaphandle kokuqhekeka kwi-weld interface. I-winch center shaft roller kufuneka ijikelezise kakuhle-kodwa ukuqina kwayo komphezulu kufuneka kudlule kwi-HRC 52 *kwaye* igcine ukuqina komphantsi ukuxhathisa ukuchaphazeka.
Yiyo loo nto iprothokholi yethu yomgangatho ibethelela isiqinisekiso kwiindawo ezine ezingaxoxisiyo:
- Ukuqinisekiswa kwezinto ezikrwada: Yonke i-coil okanye i-ingot ithwala ii-MTR ezipheleleyo, kubandakanywa uhlalutyo lwe-spectrographic kunye neengxelo zobungakanani beenkozo-hayi nje isiqinisekiso sebakala
- In-nkqubo iitshekhi CMM: Emva kokurhabaxa, ukugqityezelwa kwesiqingatha sokugqibela, kunye nokugqiba—kumatshini ofanayo olinganisiweyo, kusetyenziswa isikimu esifanayo sedatum.
- Uvavanyo olusebenzayo: Iivalve zoxinzelelo ezivavanywe kwi-1.5 × uxinzelelo olulinganisiweyo; impompo yezindlu spin-balanced kwaye ukuvuza-tshekishwe nge helium mass spectrometry
- Ukulandeleka ngokupheleleyo: Indawo nganye iqhagamshela kwinombolo yayo yobushushu, inguqulelo yeprogram yomatshini, i-ID yomsebenzisi, kunye nesitampu sexesha lokuhlola
Oku asikobunjineli obugqithisileyo. Kunqanda i-280,000 yexabiso lexesha lokuphumla xa isilinda esinye esiqhekekileyo simisa impompo yodaka ye-oyile ye-offshore iiyure ezingama-72.
Apho ukwenza ngokwezifiso kuyeka ukuba yingozi-kwaye kuqala ukuhambisa i-ROI
Abanye ababoneleli baphatha iinxalenye ezingekho mgangathweni njengezohlukileyo. Sibaphatha njengamathuba okuphelisa iindlela zokusilela. Kunyaka ophelileyo, i-OEM yaseYurophu isizisele umzobo we-AMS 5387 nozzle yesiko kunye neendlela zokupholisa ze-asymmetric. Umthengisi wabo wangaphambili ucaphule iiveki ezili-14 kwaye wala uxanduva lokutenxa kokuhamba ngaphaya kwe-±8%. Siqhube ukulinganisa kwe-thermal, sayila ngokutsha ii-baffles zangaphakathi ukuze siphucule ukufana kwesantya, kwaye sihanjiswe kwiiveki ze-9-kunye nokuphambuka kokuhamba okulinganiselwe kwi-± 2.3% kuzo zonke iiyunithi ze-12.
Njani? Ngokuphatha i-GD&T hayi njengephepha, kodwa njengolwimi olusebenzayo. Xa umzobo uchaza unyamezelo lwendawo ye-Ø0.05 mm ngokunxulumene ne-datum axis, siyaqinisekisa ukuba i-axis *phambi* komatshini—kungekhona emva. Xa ukugqiba komphezulu kufuna iRa 0.4 µm kubuso obutywiniweyo, sisebenzisa idayimani ukujika-hayi ukucola-kuba ukucola kubangela umonakalo ongaphantsi komhlaba oqalisa iintanda zokudinwa phantsi kokulayisha umjikelo.
Olo qeqesho luyakala. Nokuba ufuna iivalvu zoxinzelelo zeprototype ezintlanu okanye iziseko zempompo ezingama-300 ngekota nganye, ukuhamba kwethu okuthambileyo kutshixa ngexesha lomjikelo, isivuno sezinto eziphathekayo, kunye nesivuno sokuqala-ngaphandle kokuncama ulawulo lwesinyithi.
Ukukhetha iqabane-hayi nje umthengisi-kwi-nickel-based alloy mechanical parts
Ilungelo nickel-based alloy mechanical parts ayidibanisi nje nespekthi. Iqikelela apho i-specs isilela khona. Iyazi ukuba amandla e-AMS 5387 ehla nge-12% ukuba isisombululo se-annealing sidlula i-1180 ° C-nokuba i-MTR ithi "ngaphakathi koluhlu." Iyaqonda ukuba i-sand-cast i-T800 idinga iiparameters ezahlukeneyo zokudubula kuneenguqulelo ezifakwe kwi-investment-cast-kuba ukusabalalisa uxinzelelo olushiyekileyo kuyahluka.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza kwezo ndawo zihlanganayo zenzululwazi yemathiriyeli kunye nokwenziwa ngokuchanekileyo. Asigcini izithuba ezingenanto eziqhelekileyo. Siqhuba ulandelelwano lobunjineli malunga nomsebenzi wecandelo lakho-hayi umthamo wethu womatshini. Indawo yethu ehambelana ne-ISO e-Qingdao ihambisa amacandelo e-cobalt-nickel aqinisekisiweyo kuMntla Melika, eYurophu, nakumazantsi-mpuma e-Asia-kungekhona njengezinto zekhathalogu, kodwa njengezisombululo eziqinisekisiweyo.
Ukuba iprojekthi yakho elandelayo ibandakanya uxinzelelo oluphezulu, ubushushu obuphezulu, okanye indawo enxitywayo ephezulu-kwaye ufuna iinxalenye ezisebenza njengoko ziyilelwe, ukutshintsha emva kokutshintsha, unyaka nonyaka-qala ngokulandelelwa kwezinto, ukuqina komgangatho, kunye nokuqinisekiswa kwehlabathi lokwenyani. Hayi iincwadana. Hayi izithembiso. Ukuphunyezwa okungqiniweyo.
