Xa iinjineli zichaza amacandelo ensimbi engenasici kwiivalvu ze-hydraulic, izindlu zempompo, okanye i-winch shafts elwandle, azifuni nje isinyithi-zifuna uzinzo lwe-dimensional phantsi kwe-300 bar, ukumelana nokubola kwiindawo ezigcwele i-chloride, kunye nokunyaniseka kwe-microstructural emva konyango lobushushu. Yiyo loo nto i utyalo-mali lokugalela umzi-mveliso wensimbi engenasici ayingomthengisi-kukongezwa kobugcisa beqela loyilo.
Sibone iiprojekthi ezininzi kakhulu zimile kwinqanaba leprototype ngenxa yokuba isiseko siphatha intsimbi engenasici njengentsimbi yekhabhoni: isango elifanayo lokungena, izinga lokupholisa elifanayo, inkqubo yokuhlola efanayo. Kodwa i-316 engenastainless iyancipha i-12% ngaphezu kwentsimbi etyhidiweyo ngexesha lokuqina. I-thermal conductivity yayo sisiqingatha se-aluminium. Kwaye i-surface oxide layer-ibaluleke kakhulu kwi-passivation-ifom kuphela xa ukupholisa kulandela i-5-10 ° C / min echanekileyo ye-window post-casting. E-QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Siphatha yonke insimbi engenasici yotyalo-mali njengesiganeko sesinyithi-kungekhona inkqubo yokwenza imilo.
Ukuchaneka Kuqala Phambi kokuba uMngundo ugalelwe
Uninzi lwabathengi bacinga ukuba utyalo-mali oluchanekileyo luvela kulawulo lweqokobhe leceramic. Akunjalo. Iqala nge-wax iphethini yejometri-kunye nendlela ijometri edibana ngayo ne-alloy shrinkage. Umzekelo: indlu yepiston pump cylinder eyenziwe nge-ASTM A473 Grade 316 kufuneka ibambe ±0.05 mm kwi-Bore ID kwi-280 mm ubude. Oku sikufezekisa ngokulinganisa ukwandiswa kwewax ngokuchasene nokucutha kwealloyi yokugqibela sisebenzisa ukulinganisa kwe-thermal yangaphakathi-kungekhona iitshati zegeneric. Iqela lethu lezixhobo zokusebenza lihlengahlengisa ii-engile eziyidrafti nge-0.15 ° increments ngokusekwe kubungqingqwa bodonga, hayi itemplates eziqhelekileyo. Siye saqinisekisa le ndlela kuyo yonke imveliso ye-172 yemizimba yevalvu yoxinzelelo; I-99.4% iphumelele inqaku lokuqala le-CMM yokuqinisekisa ngaphandle kokuphinda kusebenze.
Eli nqanaba lolawulo lifuna ukuhlanganiswa ngokuthe nkqo. Asikhupheli ngaphandle isakhiwo seqokobhe, ukuthotywa, okanye ulawulo lwesithando somlilo. Indawo yethu ehambelana ne-ISO iphatha zonke ezintathu-kwaye idibanisa kwi-real-time data thermocouple kwi-crucible nganye. Xa unyibilika i-316 ingenasici, sijonga umxholo weoksijini onyibilikileyo ngokuqhubekayo. Igqithise 25 ppm? Ibhetshi ibangela ukuphambuka okuzenzekelayo kwizicelo ezingabalulekanga. Akukho ngaphandle.
Apho iCobalt Alloys kunye neStainless Steel zidibana khona
Nantsi into ephoswa ngamaqela amaninzi okuthenga: utyalo-mali lwentsimbi engenastainless aluhlukaniswanga kumsebenzi we-superalloy. Kwiziko lethu, iziko elifanayo litshisa i-AMS 5387 cobalt alloy kunye ne-CF8M engenasici. Ngoba? Ngenxa yokuba zombini zifuna ulawulo olufanayo lweatmospheric (ivacuum + iargon backfill), iindlela ezifanayo zokungunda zokufudumeza (120°C/h ukuya kuthi ga kwi-1,100°C), kunye neefestile zexesha zokushukuma ezifanayo (±90 imizuzwana). Olu qeqesho lwenkqubo enqamlezileyo luthetha ukuba ulwakhiwo lwethu olungenaziphene lufumana ilifa lemigaqo yolawulo olungqiniweyo lwe-thermal-alukho uvavanyo kunye neempazamo zokufunda ezigoso.
Thatha iindawo zempompo ezisekelwe kwi-T800. Ukuqina kwabo (42-48 HRC) kufuna isisombululo se-annealing kwi-1,120 ° C elandelwa kukucima kwamanzi kwimizuzwana engama-45. Sakhe loo ntambo yokucima kumgca wokuphosa-kungekhona njengengcamango yamva. Isiphumo: I-zero distortion kwi-142 mm-diameter impeller hubs apho abathengisi bangaphambili babike i-0.18 mm runout.
- Iivalve zoxinzelelo: ASME B16.34 Iklasi 600, eqinisekisiweyo kwi-NACE MR0175 / ISO 15156
- Izindlu zesilinda impompo yepiston: I-GD&T-ihambelana ne-ASME Y14.5-2018, kubandakanya iprofayili yolawulo lomphezulu lweeflange zokukhwelana
- Iirola zeshaft yemoto yobunjineli: Ukuqina kungqinisisiwe ngokwe-ASTM E10, ukugqiba komphezulu Ra ≤0.8 µm as-cast
- Imilomo yengxubevange yeCobalt: Uzinzo lweDimensional luqinisekisiwe emva kwemijikelo ye-thermal engama-500 phakathi -40°C kunye +220°C
Kutheni “iMathiriyeli eQinisekisiweyo eKrwada” AyiyoNtengiso nje
"Sisebenzisa i-certified stainless steel" ibonakala kwi-83% yeewebhusayithi zababoneleli. Kodwa ukuqinisekiswa akuthethi nto ukuba ukulandeleka kuyeka kwithegi yekhoyili. Kwindawo yethu, inani lobushushu ngalinye liqukuqela ngokuthe ngqo kwinkqubo yethu ye-ERP-kunye neemephu eziya kwi-castings ethile ngekhowudi ye-laser-etched lot kuyo yonke indawo. Xa umthengi ecela umnombo wezinto ezipheleleyo zomyalelo wevalve ye-subsea, sazisa iingxelo zovavanyo lokusila, iilog zohlalutyo lwe-spectrographic, kunye neerekhodi zexesha le-furnace-zonke zibotshelelwe kumanani okuphoswa komntu ngamnye. Elo nqanaba lokubonisa izinto elubala akukhethi. Iyafuneka ukuze i-API 6A ithotyelwe-kwaye ibhakiwe kuhambo lwethu lomsebenzi, ayibotshwanga kuphicotho.
Sifumana i-316, 304L, kunye ne-duplex 2205 ngokukodwa kwii-mills ezine-EN 10204 3.1 isatifikethi-kwaye siqinisekise i-chemistry xa siyifumana sisebenzisa i-LIBS spectrometry ephathwayo. Ukuba i-chromium iwela ngaphantsi kwe-16.5% kwisampulu ye-304L, yonke ikhoyili ivalelwa yodwa ngaphambi kokuba yothulwe. Akukho ngaphandle. Hayi “oku kube kanye kuphela.”
Ukuhanjiswa Kwenyani Kuthetha Ukuqikelelwa Kwenyani
Buza ababoneleli abahlanu ngexesha lokukhokela kwintsimbi yotyalo-mali, kwaye uya kufumana iimpendulo ezintlanu-kunye noluhlu oluthatha iiveki ezisi-8 ukuya kwezi-22. Olwethu lulungisiwe: iiveki ze-14 kwinqaku lokuqala, iiveki ze-10 zokuphindaphinda ii-odolo-eziqinisekisiweyo. Njani? Ngokutshixa umthamo kwangethuba: i-30% yezikhululo zethu zokwakha amaqokobhe zigcinelwe iipateni ezikhethekileyo, kwaye iziko lethu le-vacuum induction ishedyuli yokutshisa i-stainless kwiibhloko ezinikezelweyo zeveki. Akukho kutshintshiswa kwealloyi phakathi ebaleni. Akukho mngcipheko wosulelo. Akukho kulibaziseka okumangalisayo okuvela kwizibonelelo ekwabelwana ngazo.
Siqinisekisa esi sithembiso yonke imihla. Kwikota yokugqibela, i-97.2% yee-odolo zensimbi ezingenasici zithunyelwa ngomhla okanye ngaphambi komhla wokuzibophelela. Umahluko we-2.8%? Zonke zilandelelwa kwiinguqu ezicelwe ngumthengi emva kokuvunywa kwesixhobo-hayi ukusilela kwenkqubo yangaphakathi.
Ukuba iprojekthi yakho elandelayo idinga iqabane eliphatha utyalo-mali lwensimbi engenasici njengesinyithi, hayi ukuvelisa-udinga utyalo-mali lokugalela umzi-mveliso wensimbi engenasici yakhelwe ukuchaneka, hayi umthamo. QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD. isebenza ngaloo ndlela-kungekhona ngenxa yokuba ilungile, kodwa ngenxa yokuba uxinzelelo oluphezulu, ukubola okuphezulu, ukuthembeka okuphezulu kwezicelo akushiyi indawo yokulala. Ukuchaneka akulosebe apha. Yinkqubo yokusebenza.
