Titanium impeller yog ib qho kev sib hloov ua los ntawm titanium los yog titanium alloy, dav siv hauv cov twj centrifugal, compressors, turbomachinery thiab lwm yam khoom siv, nrog lub zog siab, corrosion kuj, lub teeb yuag thiab zoo heev - kub ua haujlwm.
Cov yam ntxwv tseem ceeb ntawm titanium impellers: lub zog tshwj xeeb → lub zog rau qhov hnyav piv ntawm titanium alloy yog qhov siab heev, lub zog tensile ntawm titanium alloy tuaj yeem ncav cuag ntau dua 800MPa, uas ua tau raws li qhov xav tau ntawm kev kub siab piv thiab kev kub ceev ua haujlwm, thiab tsim nyog rau cov ntawv thov uas yuav tsum tau txo qhov hnyav thaum tuav lub zog (xws li aero xyaw); Corrosion resistance → Titanium qhia tau hais tias zoo heev corrosion kuj nyob rau hauv huab cua ntub dej, dej hiav txwv, chloride ib puag ncig thiab ntau yam acids thiab alkalis, thiab qhia tau hais tias zoo heev tiv thaiv corrosive xov xwm xws li seawater, muaj zog acid, thiab muaj zog alkali, thiab yog haum rau chemical kev lag luam, seawater desalination thiab lwm yam teb. Kev kub siab ua haujlwm → qee cov titanium alloys tuaj yeem ua haujlwm ntev ntawm 500 degree, haum rau siab - qhov kub thiab txias xws li tshuab aero; Kev ua haujlwm qaug zog yog qhov zoo → titanium impeller muaj lub neej qaug zog ntev hauv kev hloov pauv. Qhov ceev ntawm qhov qis- ntom → yog li 4.5 g / cm³, uas yog li 60% sib dua li cov hlau, tab sis lub zog yog ze rau lossis txawm tshaj li ntawm qee qhov siab - lub zog steels.
Daim ntawv thov:
Aerospace: Aero engine compressor hniav, kiv cua rotors (xws li, F-22 fighter dav hlau, Boeing 787 cav)
Marine kev lag luam: marine thrusters, seawater twj impellers (seawater corrosion resistance)
Cov cuab yeej siv tshuaj: Centrifugal compressor impellers rau thauj cov roj corrosive lossis kua
Cov khoom siv kho mob: cov khoom siv cog tau zoo xws li cov twj siv lub plawv (zoo biocompatibility)
Kev lag luam hluav taws xob: geothermal zog tsim chav turbines, hydrogen roj cell cua compressors
Kev tsim cov txheej txheem ntawm titanium impellers yuav tsum tau muab cov yam ntxwv ntawm cov khoom siv nrog cov txheej txheem nyuaj, thiab cov txheej txheem tseem ceeb suav nrog: Kev nqis peev casting → Txheej txheem: siv graphite lossis ceramic pwm core, casting thiab molding los ntawm lub tshuab nqus tsev melting, haum rau txoj kev nkhaus hniav (xws li aviation impellers). Cov yam ntxwv tseem ceeb: pwm kub yuav tsum tswj ntawm 110-130 degree, thiab nws yuav tsum tau tiv thaiv los ntawm argon roj thaum lub sij hawm nchuav los tiv thaiv oxidation. Tom qab{12}}kev kho mob: Nqus annealing (750{13}}800 degree) thiab kub isostatic nias (103MPa, 920 degree) yuav tsum tau tshem tawm qhov tsis xws luag. Forging txheej txheem → xaiv cov khoom siv: Kev xaiv zoo tshaj plaws ntawm forged titanium alloy Gr.5 txo qhov porosity, shrinkage thiab lwm yam tsis xws luag piv nrog casting Gr.5, thiab nce yield los ntawm 50%. Tus qauv tsim: Rov qab-bending hniav thiab seem sib npaug zog yog siv los ua kom zoo dua hydrodynamic kev ua tau zoo. Additive manufacturing thiab CNC machining → 3D printing: Resin qauv yog tsim los ntawm lub teeb curing molding technology, ua ke nrog ceramic slurry grouting los tsim lub plhaub molded, haum rau me me batch customization. Kev Txiav Txim: Siv AlTiN-coated carbide cov cuab yeej los ua kom zoo rau kev txiav thiab txo cov cuab yeej hnav.
Nyuaj hauv kev siv thev naus laus zis: txheej txheem fwj, tsis zoo thermal conductivity ntawm titanium alloy, yooj yim los tsim thermal stress thaum lub sij hawm ua, thiab yuav tsum tau tsim tshiab tshuab cua txias. Complex nkhaus nto casting xav tau los tswj cov peev txheej sealing kom tsis txhob muaj qhov tsis xws luag. Composite manufacturing: Sib txuas ntxiv kev tsim khoom nrog precision casting kom ua tiav ntau- cov khoom sib xyaw impellers. Kev kho saum npoo: Txhim kho qhov tawv tawv los ntawm micro-arc oxidation lossis laser cladding kom ntev kev pab cuam lub neej. Kev txawj ntse ntau lawm: AI algorithms tau qhia los ua kom zoo tshaj qhov kev txiav thiab txo kev siv hluav taws xob los ntawm 15% -20%.
