Xa iinjineli kuMntla Melika okanye eYurophu kufuneka a China metal casting umenzi ekwaziyo ukuhambisa iivalvu zoxinzelelo ezibambe ukunyamezelana okuqinileyo kwi-350 bar-okanye i-cobalt alloy nozzles ezisinda kwi-650 ° C kwiindibano zempompo ye-oilfield-ayikhangeli nje "isiseko sexabiso eliphantsi." Bakhangela ulawulo lwe-metallurgical olungqiniweyo, uqeqesho lwe-dimensional, kunye nokunyamezela i-zero yokungahambelani kwe-microstructural. Kulapho ukuchaneka kubaluleke ngaphezu kwexabiso-kwaye apho QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ufumana iiodolo eziphinda-phindayo kwii-OEM ze-hydraulic system kunye nezihlanganisi zezixhobo zaselunxwemeni.
Ayizizo zonke iiCastings ezidalwe ngokulinganayo-Ingakumbi phantsi komthwalo
Sibone iiprojekthi ezininzi zilibazisekile-hayi ngeziphene zoyilo, kodwa ngezinto ezimangalisayo. Indlu yesilinda yempompo yepiston eyenziwe ngoomatshini bentsimbi esantiweyo iyasilela kuvavanyo lokungcangcazela ngenxa yokuba ubalo lwamaqhuqhuva egraphite luwe ngaphandle kwenkcazelo ye-ASTM A278 yoKlasi lwama-30. Iplagi ye-cobalt-nickel iyaqhekeka ngexesha lokuhamba ngebhayisekile eshushu ngenxa yokuba isithuba sengalo ye-dendrite se-as-cast sasohlukana ngaphaya kwe-±12 µm kubushushu. Ezi ayingomngcipheko wethiyori. Ziindlela zokungaphumeleli eziqinisekisiweyo kwintsimi esincede abathengi ukuba baziphephe ukusukela ngo-2014.
I-QINGDAO QIANGSENYUAN ayikuphathi ukuphosa njengenkqubo ezimele. Iyithatha njengenyathelo lokuqala elibalulekileyo kwikhonkco elidityaniswe ngokuqinileyo: ukuphosa → isiqabu soxinzelelo → Umatshini we-CNC → unyango lobushushu → ukuqinisekiswa komphezulu wemfezeko. Indawo yabo ehambelana ne-ISO iqhuba ukufakwa kotyalo-mali kumacandelo amancinci e-AMS 5387 kunye nokuphosa kwesanti eluhlaza kwizindlu zentsimbi ezinobunzima-nganye ineeprofayili ezinikezelweyo zesithando somlilo, iilogi zokupholisa, kunye nokuqinisekiswa kwebhetshi ye-spectrographic. Yonke inyibiliko ithwala ukulandeleka okugcweleyo: inani leqashiso, ubushushu obuthululwayo, ixesha lokuqiniswa, kunye neengxelo eziqinisekisiweyo zovavanyo lokusila ezivela kubaboneleli abaphicothiweyo.
Oku akubhekiseli "kwintlanganiso yentlanganiso." Kumalunga nokulawula izinto eziguquguqukayo apho amaphepha anqabileyo angakhankanyi-njengokusasazwa koxinzelelo olushiyekileyo emva kokushukuma, okanye indlela ukuqhelaniswa neenkozo kubuchaphazela ngayo ubomi bokudinwa kwi-winch centre shaft roller ejikelezayo phantsi kwe-cyclic torsion. Yiyo loo nto iinjineli zabo zihlala zijonga ii-callouts ze-GD&T ngokuchasene nokuphosa iimephu ezinciphayo-hayi nje iiplani.
Kutheni le nto iCobalt Alloys ifuna ngaphezulu kuneLayisensi yokufumana nje
Abanye abavelisi badwelisa "i-cobalt alloy capability" kwiwebhusayithi yabo. Abambalwa banokuqhubeka bephosa iindawo ezisekelwe kwi-T800 kunye ne-≤0.8% ye-porosity kwiindawo ezibalulekileyo zokuhamba kwendlela-okanye ubambe i-± 0.015 mm ukunyamezela kwendawo kwiibhore ezintathu ze-coaxial kwi-AMS 5387 yepompo yezindlu emva kokusila kokugqibela. Umahluko ulele kubunini benkqubo.
QINGDAO QIANGSENYUAN ungumnini lonke ixabiso stream: ukuthenga izinto ekrwada (kunye nezivumelwano ngqo Haynes 25 kunye Stellite 6 elingana), vacuum induction ukunyibilika, iqokobhe leceramic investment cast, ezintandathu-axis CNC machining nge-in-probing probing, kunye HIP (hot isostatic pressing) for nozzles-nozzles. Akukho ikontraki engaphantsi. Akukho handoffs. Xa umthengi ethumela umzobo weplagi ye-cobalt ye-alloy engekho-standard kunye neziteshi zokupholisa zangaphakathi, iqela elifanayo liphatha ukuhlaziywa kwe-metallurgical, ukubunjwa kwe-mold flow simulation, i-machining strategy, kunye nokuvavanya ukuvuza-konke phantsi kophahla olulodwa.
Bayayazi nento *abangafanele bayenze. Umzekelo: isanti ephosa i-cobalt alloys imema ulwahlulo lwe-carbide. Ngoko basebenzisa utyalo-mali-nangona yongeza i-18% ukukhokela ixesha-kuba ihambisa ubunzima obufanayo (i-HRC 42-46 kulo lonke icandelo) kwaye ikhuphe imfuno yeendleko ze-post-machining rework ngenxa yokuhlanganiswa kwesigaba esinzima.
Ukusuka kuMzobo ukuya kuHambiso: Apho iNkxaso yobuNjineli ngenene yongeza ixabiso
"Ungayenza lonto?" ngumbuzo wokuqala ongalunganga. Efanelekileyo ithi: "Yintoni eya kusilela kuqala-kwaye siyinqanda njani?" Yilensi QINGDAO QIANGSENYUAN esebenzayo ngexesha lophononongo lobunjineli.
- Iqela labo lifakela ii-engile zokuyila ezingahambelaniyo nokususwa kweqokobhe le-ceramic-ngaphambi kokuba kuqale izixhobo
- Bacebisa uhlengahlengiso oluncinci lwe-GD&T (umzekelo, ukuguquka ukusuka kunyamezelo lwendawo ukuya kulawulo lokubaleka kwi-shaft ejikelezayo) ukuphucula isivuno sokuqala.
- Baqinisekisa imijikelo yonyango lobushushu ngokuchasene nobunzima benxalenye yokwenyani-hayi iitshathi eziqhelekileyo-ukunqanda ukugqwetheka kwiziseko zempompo yentsimbi.
Le asiyothiyetha yengcebiso. Yingxelo ebhaliweyo, ebuyiselwe kwiiyure ezingama-72, kunye nemizobo echazwe kunye neengcebiso ezizezinye zezinto (umzekelo, ukutshintshela kwi-CF8M ukuya kwi-UNS S32750 duplex yokuxhathisa i-chloride kwizicelo zaselwandle). Ukuqhuba kweprototype, bathumela iingxelo zokuhlola ezinobungakanani kunye ne-CMM yokwaleka kwamafu ngokuchasene nejometri yegama-ukuze abathengi baqinisekise ukuba bafanelekile ngaphambi kokuba bazibophelele kwimveliso.
Ukukhetha uMvelisi weNsimbi yaseTshayina ayiyoJografi- imalunga nokugcinwa kweSango
Ukufunwa kwehlabathi akukho malunga nokufumana esona sicatshulwa sisezantsi. Kumalunga nokuchonga ukuba ngubani olawula amasango: isango elimisa iingots eziphantsi, isango elilahla ukuphosa okungahambi kakuhle ngaphambi komatshini, isango elimisa ukuthunyelwa kude kube uvavanyo olusebenzayo luqinisekisa ukuqhuma kwengcinezelo kwi-1.5 × umthwalo olinganisiweyo.
Amandla e-QINGDAO QIANGSENYUAN ayilinganisi-kukukhetha. Zizodwa kwiindidi ezine zokunyaniseka okuphezulu: iinxalenye zomatshini we-CNC, i-cobalt-nickel alloy components, i-iron castings, kunye ne-steel / steel stainless castings. Ayikho enye. Olo gxininiso lwenza ulwazi lwenkqubo enzulu, ukusombulula ingxaki ngokukhawuleza, kunye neziphumo ezingaguqukiyo kuzo zonke iihydraulic, ioyile kunye negesi, kunye nokusetyenziswa kwemoto enzima.
Ukuba iprojekthi yakho elandelayo ibandakanya iivalvu zoxinzelelo oluphezulu, izindlu zempompo, okanye i-shafts ebaluleke kakhulu-kwaye ufuna China metal casting umenzi ephatha i-metallurgy njengobunjineli, hayi ukuvelisa-ukuqala ngokulandelelwa kwezinto, ukuqeqeshwa komgangatho, kunye nokuthintela ukusilela kwehlabathi lokwenyani. Hayi izilogeni zokuthengisa.
