Xa iinjineli zidinga iindawo zentsimbi ezichanekileyo ezisindayo kuxinzelelo oluphezulu, ukunxiba okugqithisileyo, okanye imeko-bume eyonakalisayo-ingakumbi kwiinkqubo ze-hydraulic, izixhobo ze-oyile kunye negesi, okanye i-heavy-duty-duty pump assemblies-ayikhangeli nje * nayiphi na i-Foundry. Bakhangela a ilahleke umzi-mveliso wokugalela isanti ngolawulo oluqinisekisiweyo kwi-metallurgy, ijometri, kunye ne-microstructure-kungekhona enye ephatha utyalo-mali kunye nokuphosa isanti njengokhetho olunokutshintshwa.
Sibone iiprojekthi ezininzi zilibazisekile ngenxa yokuba umthengisi uthembise “ukwenziwa ngokuchanekileyo” kodwa wahambisa iinxalenye ezinokwakheka okuziinkozo okungangqinelaniyo, ukukhukuliseka okunecala emva konyango lobushushu, okanye iziphene ezingaphezulu ezinyanzelise ukuba ziphinde zisebenze kwakhona. Oyena nobangela? Isibonelelo esiqhuba ukuphosa njengenkqubo ezimeleyo-eyahlukileyo kumatshini, isayensi yezinto eziphathekayo, kunye nokuqinisekiswa okusebenzayo. Kwi-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha i-wax elahlekileyo (utyalo-mali) kunye nokuphosa isanti kungekhona njengezinye iindlela-kodwa njengezixhobo ezincedisayo kwi-workflow eyodwa, edibeneyo ngokuthe nkqo. Yiloo ndlela esibamba ngayo ukunyamezela kwe-± 0.05 mm kwimibhobho ye-cobalt alloy kunye nokugcina ubunzima obufanayo kuzo zonke izindlu zepompo ze-AMS 5387-nokuba ku-200 mm ubukhulu bodonga.
Kutheni “iFactory yokuphosa isanti yeWax elahlekileyo” iligama elilahlekisayo-kwaye eyona nto uyidingayo
Ibinzana elithi “ifektri yokuphosa isanti elahlekileyo” libhidanisa iinkqubo ezimbini ezahlukileyo: utyalo-mali (usebenzisa imixokelelwane ye-ceramic yamaqokobhe enziwe malunga neepateni zewax) kunye nokugalelwa kwesanti (kusetyenziswa ukubumba kwesanti edityanisiweyo). Akukho nanye ithatha indawo yenye—kwaye akukho nto inika ukuchaneka iyodwa. Ukuchaneka kokwenyani kuvela kuphela xa zombini zixhaswa bubuchule obuthathu obungenakuxoxisana:
- Ukusetyenzwa kwe-alloy eqinisekisiweyo ngezinto-ngokukodwa kwi-cobalt-nickel superalloys efana ne-T800 kunye ne-AMS 5387, apho ukuphambuka okuncinci kwikhabhoni okanye umxholo we-chromium kubangela ukuqhekeka kwangaphambi kwexesha phantsi kokulayisha i-cyclic;
- Ukuqhubekeka komdaniso kulo lonke utshintsho lokusahlela ukuya kumatshini-iiakhawunti zoyilo lokungunda oluthetha ukushwabana, ukulungiswa komatshini kuhambelana nemiphezulu yedatha, kunye nokuhlolwa kweCMM kuqinisekisa ukuphosa okukrwada kunye neenxalenye ezigqityiweyo ngokuchasene nesakhelo se-GD&T esifanayo;
- Ukulandeleka okusebenzayo-hayi nje amanani ebhetshi, kodwa iirekhodi ezigcweleyo ezinxibelelanisa indawo nganye kwilogi yayo yokunyibilika, ijiko lonyango lobushushu, imephu yobunzima, kunye nesiphumo sovavanyo lokugqibela loxinzelelo.
Leyo yinyani emva kwendawo yethu ethobela i-ISO eQingdao. Asikhupheli ngaphandle uhlalutyo lwesinyithi. Asiyamkeli "i-near-net-shape" njengesizathu sokutsiba uphononongo lomgangatho wenqaku lokuqala. Xa umthengi ethumela umzobo wendlu yesilinda yempompo yepiston, iinjineli zethu ziphendula kwiiyure ezingama-48-hayi ngekowuti, kodwa ngempendulo echaziweyo: "Le fillet radius iya kubambisa i-porosity ngaphandle kokuba siguqule isango; nantsi indlela yokufanisa." Ngamava lawo-hayi ukuthengisa.
Apho uninzi lwaBaboneleli Besilela khona—kwaye Siwuvala Njani uMsantsa
Abanye baxoxa ukuba ukuchithwa kwesanti akukwazi ukuhambelana nokuchithwa kotyalo-mali ngeenkcukacha. Abanye bathi i-cobalt alloys "inzima kakhulu ukuphosa ngokuthembekileyo." Zombini ezi nkcazo ziyinyani-ukuba usebenza nesiseko senjongo ngokubanzi. Kodwa ekusebenzeni, amanqaku angaphumeleli phantse ahlala eyinkqubo, kungekhona ezobugcisa.
Silandelele iindawo eziyi-127 ezikhatywayo kwiiprojekthi zabathengi abali-19 kulo nyaka uphelileyo. Kuphela yi-3% eyasilelayo ngenxa yeziphene eziphathekayo. Ngaphezulu kwe-68% ilandelelwe emva kolindelo olungahambelaniyo: imizobo ebhalwe “njengokuphoswa kwesiphelo” kodwa ifuna umphezulu wokutywina osebenzayo; ikhwelo lonyamezelo lisetyenziswa kwiimpawu ezingenakwenzeka ukuba zihlolwe ngaphandle kokwahlulwa okutshabalalisayo; okanye iinkcukacha zonyango lobushushu ezibhalelwe isitokhwe esisetyenzisiweyo-hayi ukuphoswa kwe-microstructures.
Impendulo yethu ayikokubuyela umva-kukungena ngaphambili. Iprojekthi nganye iqala ngokuphononongwa ngokudibeneyo komzobo. Sifaka iflegi kwiingxabano ze-GD&T ngaphambi kokuba kuqale isixhobo. Siqinisekisa ushicilelo oluphambili lwemfezeko ye-shakeout-hayi nje ukuchaneka komda. Kwaye siqhuba uvavanyo oluthululwa ngeendlela ezichazwe ngabathengi be-NDT (RT, UT, okanye ukungena) kwiiyunithi ezintlanu zokuqala-hayi eyokuqala engamashumi amahlanu. Yiyo loo nto i-92% yee-odolo zethu zomthamo ophakathi zithunyelwa ngeshedyuli, ngaphandle kokubaleka okulinganayo kuhlolo lokugqibela.
Ukuchaneka kwehlabathi lokwenyani: Ukusuka kuKhetho lwe-alloy ukuya kwiNdawo egqityiweyo
Thatha iplagi ye-cobalt alloy esetyenziswa kwiimpompo zenaliti engaphantsi kwamanzi. Kufuneka itywine kwi-15,000 psi ngelixa ixhathisa i-sulfide stress cracking. Ukugalelwa kwesanti okusemgangathweni kuya kuswela ukutya okuziinkozo okufunekayo ukuxhathisa ukudinwa. Utyalo-mali oluqhelekileyo lunokwazisa ukushwabana kancinci kwisiseko seflange. Isisombululo sethu? Ukusetyenzwa kweHybrid: utyalo-mali-luphose ummandla wokutywina obalulekileyo usebenzisa i-ceramic cores yeecontours zangaphakathi eziqinileyo, emva koko utshintshela kwisanti elawulwayo yokubumba i-flange ekhuphukayo-eyenziwe kwiseto enye usebenzisa izixhobo zokufunxa zesiko ezigcina uzinzo lwe-thermal.
Imathiriyeli ekrwada iza yaqinisekiswa kwangaphambili kwi-AMS 5719, inamaxwebhu apheleleyo embali yobushushu. I-Post-casting, iqashiso ngalinye lifumana i-spectrometry yokufunda ngokuthe ngqo kunye novavanyo lwe-tensile nge-ASTM E8. Amacandelo okugqibela adlula uvavanyo lwe-helium yokuvuza kwi-1 × uxinzelelo lokusebenza-kwaye sigcina yonke idatha ye-10 iminyaka.
Oku akuyothiyori. Yindlela esiye sahambisa ngayo i-4,200 AMS 5387 iinqununu zepompo kumenzi we-Tier-1 hydraulic systems eYurophu-kunye nokusilela kwintsimi kwiinyanga ze-36 zokusebenza kwiirigi zokuqhuba i-offshore.
Ukukhetha iqabane lakho akukho malunga namagama eNkqubo-Kumalunga nokuziphatha okumiliselweyo
A ilahleke umzi-mveliso wokugalela isanti ileyibhile ayikuxeleli nto malunga nokuba loo mzi-mveliso uyayiqonda indlela i-cobalt's solidification uluhlu oluchaphazela ngayo ukutya kwe-interdendritic-okanye kutheni i-angle eyi-0.3 mm yedrafti ibaluleke kakhulu kwi-T800 casting kune-stainless steel 316.
Okubalulekileyo kukuba umthengisi wakho ungumnini wetsheyini epheleleyo: ukuthengwa kwemathiriyeli kunye nezixhobo eziphicothiweyo zomthengisi, i-spectroscopy yangaphakathi, i-CNC yomatshini ilungelelaniswe ukuba ibe needatum, kunye nokuhlolwa kokugqibela okubotshelelwe ngokuthe ngqo ekusebenzeni okusebenzayo-hayi nje ukuthobela iibhokisi zokukhangela.
QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. ayithengisi iinkonzo zokuphosa. Sihambisa i-mission-critical components zetsimbi-ezobunjineli, zaqinisekiswa, kwaye ziyalandeleka ukusuka kwi-alloy etyhidiweyo ukuya kwindawo efakiweyo. Ukuba iprojekthi yakho elandelayo ifuna ingqibelelo ephantsi komthwalo, ukuhambelana kwe-microstructural kwiibhetshi, okanye udibaniso olungenamthungo phakathi kokuphosa kunye nomatshini ochanekileyo-udinga ngaphezulu kwesiseko. Udinga iqabane eliphatha onke amacandelo njengokungathi ukungaphumeleli kwalo kuya kumisa impompo, ukumisa i-winch, okanye ukuvala i-wellhead.
