Li-cast steel castings li fana ka matla a ke keng a lekanngoa, ho tiea, le botsitso ba mocheso moo ho hloleha e seng khetho - li-hydraulic manifolds tlas'a 350 bar, offshore pump housings tse pepesehileng metsi a leoatle le lehlabathe, kapa li-winch center shaft rollers holim'a baepolli ba merafo ba jereng meroalo ea lithane tse ngata. Tsena ha se likarolo tsa tšepe feela. Ke liqeto tse jereng meroalo tse entsoeng lehlabatheng la motheo mme li netefalitsoe li-lab tsa metrology.
Re bone merero e mengata e ema ha lienjineri li hlakisa "tšepe" ntle le ho hlakisa boemo, boemo ba kalafo ea mocheso, kapa litlhoko tsa bohlokoa tsa libaka. Sehlopha sa ASTM A216 WCB valve se ka 'na sa feta hydrotest-empa se phatloha nakong ea ho palama baesekele e futhumetseng haeba se tloaelehile ho e-na le ho tima le ho halefa. Ntlo ea pompo ea pompo ea piston e entsoeng ka bareng e entsoeng e boloka nako empa e tela ho hanyetsa mokhathala oa isotropic ha e bapisoa le tšepe ea tšepe e nang le heke e kentsoeng hantle le ka mor'a tjheseletsa. Ke ka hona li-castings tsa tšepe li lula li sa nkeloe sebaka ke litsamaiso tsa bohlokoa tsa indasteri: li kopanya tsoelo-pele ea sebopeho le tokoloho ea moralo ha ho boqapi kapa boqapi bo ka bapisoang.
Lintlha tse tharo tsa tekheniki li arola tšepe e sebetsang hantle haholo ho tsoa ho thepa:
- Taolo ea metallurgic e qala pele e tšela. Taelo ea thepa e tala ha se lipampiri-ke litlaleho tsa tlhahlobo ea leloala tse ikhethileng bakeng sa khabone, chromium, molybdenum, le likarolo tse setseng joalo ka koporo le thini. Re kile ra hana mocheso o felletseng oa ASTM A352 LCB hobane karohano ea sebabole e feta 0.025% sebakeng sa riser-e sa bonahaleng ka tlhahlobo ea pono empa ho netefalitsoe hore e bolaea ka sekhahla sa mocheso o tlase oa mocheso.
- Botšepehi ba dimensional bo itšetlehile ka kopanyo ea ts'ebetso - eseng feela ho lahlela. Motheo oa pompo ea 420 mm OD o tlameha ho ts'oara ± 0.15 mm chitja ha o lutse litulo * kamora* ho theola khatello ea maikutlo, ho sebetsa ka mochini, le tlhahlobo ea ho qetela. Seo se hloka mohlala o hokahaneng oa litumello tsa shrink, gating e tiileng ea tataiso, le ts'ebetso ea CNC e bonts'ang li-datum - eseng feela tse felileng.
- Boleng ba bokaholimo bo hlalosa ts'ebetso-eseng qetellong. Nozzle ea AMS 5387 cobalt alloy ha e benngoe bakeng sa ponahalo. Sebaka sa eona sa ka hare sa 0.8 µm Ra se fokotsa khoholeho ea cavitation e bakoang ke moferefere. Li-fillets tsa eona tsa ka ntle li qoba khatello ea maikutlo tlas'a li-spikes tsa khatello ea cyclic. Bokaholimo ha bo botle. Ke ts'ebetso e lekantsoeng.
Ba bang ba pheha khang ea hore ho etsa matsete ho fana ka sephetho se betere ho feta sa lehlabathe - joale ke hobane'ng ha u sebelisa lehlabathe ho hang? Hobane lehlabathe le sebetsana le boima, jiometry, le ho rarahana ha motsoako o qhibilihisang mefuta ea matsete. A 220 kg koloi ea boenjiniere winch center shaft rolara e nang le likanale tse pholileng tsa ka hare le li-flange tsa asymmetric? Ho lahla lehlabathe ho laola likhahla tsa mocheso likarolong tse teteaneng; mekhoa ea lichelete e ne e tla khopamisa kapa ea chesa. Thekiso ea 'nete ha e fele ha e bapisoa le ho nepahala - ke litšenyehelo tse felletseng tsa ho ba le beng ba hau khahlano le boiketlo ba ts'ebetso e le 'ngoe. Ka linako tsohle re li kopanya ka bobeli: lihlopha tsa meralo ea lehlabathe le lisebelisoa tse kenyang chelete bakeng sa libaka tse senyehang-ebe re li kenya mochine e le karolo e le 'ngoe ea ts'ebetso.
Taeo ena e nyalisitsoeng e hloka bokhoni bo otlolohileng. U ke ke ua fana ka kalafo ea mocheso ka ntle 'me u lebelletse matla a phetoang a phetoang ho pholletsa le likarolo tsa lebota la 120 mm. U ke ke ua itšetleha ka NDT ea motho oa boraro ha tlhahlobo ea ultrasonic e tlameha ho etsa 'mapa oa porosity ka har'a 3 mm ea sebaka se tiisitsoeng sa mochini. Ho QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., mong le e mong ho akhela tšepe e feta ka liheke tse 'nè tse ke keng tsa buisanoa: netefatso ea thepa e tala e netefalitsoeng (e nang le CoA cross-referenced to heat number), in-process CMM scanning at green and post-heat-treat treatment, 100% MPI / UT libakeng tse mahlonoko ka ASTM E165 / E1444, le ts'ebetso ea ho qetela ea ts'ebetso-joaloka khatello ea khatello ea ho hlahloba hydraulium leak × 5. 1×10⁻⁶ mbar·L/s kutlo.
Phello e bile efe? Likarolo tse phelang moo ba bang ba khathalang teng. Li-valve tsa khatello tse sebetsang ka ho tsoelang pele ho 200 ° C meleng ea mouoane oa mocheso oa mocheso oa mocheso. Matlo a li-cylinder a mamella lipotoloho tsa khatello tse limilione tse 15 ho li-hydraulic actuators tse ka tlas'a leoatle. Metheo ea pompo e monyang ho sisinyeha ha torsional ha e ntse e boloka tekano ka har'a 0.03 mm ho feta 3-meter spans. Tsena ha se lintlha tsa theory. Ke liphetho tse netefalitsoeng tšimong - tse tlalehiloeng litlalehong tsa lits'ebeletso tse tsoang lipulong tsa North Sea, libaka tsa lehlabathe la oli la Alberta, le likepe tsa likepe tsa Asia Boroa-bochabela.
Ha u sheba pele, moeli ha se li-alloys tse matla feela-ke ho kopanya ka bohlale. Re ntse re holisa R&D ka har'a mekhoa e nyalisitsoeng ea "casting-machining": ho kenya litekanyo tsa khatello ka kotloloho ka har'a hlobo ea lehlabathe ho lekola khatello ea maikutlo ka nako ea nnete; ho sebelisa litšoantšo tsa mocheso tse tsamaisoang ke AI ho bolela esale pele ho fokotseha ha micro pele machining a qala; tse tšoanelehang tse ncha tsa T800-based cobalt-steel composite bakeng sa li-impellers tsa pompo tse phahameng haholo. Empa ha ho le e 'ngoe ea sena ea bohlokoa haeba 'nete e sa bonahaleng e lahleha lipakeng tsa ho taka le ho fana. Ke ka lebaka leo boitlamo ba rona bo matla bo lulang bo sa fetohe: e mong le e mong ho akhela tšepe likepe tse nang le traceability e felletseng ea lintho tse bonahalang, litlaleho tsa tlhahlobo tse lumellanang le GD&T, le ntlha e le 'ngoe ea boikarabello ba tekheniki - ho tloha tlhahlobong ea pele ea sekeche ho isa tlhahlobong ea ho hloleha ha masimo.
