Laser claddingyog ib qho tseem ceeb ntawm kev siv laser ua tshuab. Thaum lub sij hawm cladding txheej txheem, nyias txheej ntawm matrix khoom yog irradiated los ntawm ib tug high-zog ceev ceev (feem ntau 10.2 ~10 4 W/mm2 ) laser beam kom yaj, sib tov nrog tib lub melted muab tub lim cov ntaub ntawv, thiab tsim kom muaj ib tug tshav kub-tshem tawm tsam ntawm ib tug tej thickness, tsim ib tug metallurgically bonded cladding txheej nyob rau saum npoo ntawm lub substrate kom ua tiav nto kev hloov kho thiab additive manufacturing. Cov duab hauv qab no qhia txog lub hauv paus ntsiab lus ntawm laser cladding.
Nyob rau hauv xyoo tas los no, laser remanufacturing kho tshuab tau sim tshem tawm rotor ncej hnav. Lub rotor yog lub tshuab hluav taws xob lub tshuab ua haujlwm tseem ceeb thiab yuav tsum tiv taus kev ua haujlwm hnyav xws li qhov kub thiab txias, kev kub siab, kev kub ceev, thiab kev ntxhov siab. Txawm li cas los xij, vim yog cov roj lubricating zoo, impurities, thiab lwm yam kev ua haujlwm tsis zoo, rotor phau ntawv journal yog qee zaum hnav, cuam tshuam rau chav turbine kom muaj kev nyab xeeb thiab ruaj khov.
Piv nrog cov tsoos electroplating, tshuaj hla kev, thermal spraying, arc vuam, thiab lwm yam txheej txheem ib txwm siv, laser cladding tshuab muaj qhov zoo ntawm kev sib koom ua ke muaj zog, me me tshav kub cuam tshuam cheeb tsam, tsawg dilution tus nqi, me me deformation, me me tom qab ua nyiaj pub dawb, muaj zog cheeb tsam. xaiv, thiab siab automation.
Tom qab 8 xyoo ntawm kev ua haujlwm ntawm chav turbine hauv kev pabcuam hauv cov chaw tsim hluav taws xob, phau ntawv xov xwm ntawm lub tshuab hluav taws xob qis tau raug kev puas tsuaj ntau yam, uas cuam tshuam rau kev nyab xeeb ntawm chav tsev. Raws li ib tug remanufacturing txoj kev uas tsis muaj tshav kub input, laser cladding tau qhia nws adaptability rau lub additive kho ntawm tsawg-siab rotors nrog siab qhov tseeb qhov yuav tsum tau thiab nyuaj welding ntawm lub cev cov ntaub ntawv. Vim lub zog ceev ntawm laser cladding, nws muaj peev xwm ua kom tiav kev kho ntawm rotor phau ntawv journal nrog tsawg welding thaum tshav kub kub.
Cov khoom siv ua haujlwm kho yog lub chaw ua haujlwm laser cladding txav tau yooj yim, uas tuaj yeem thauj tau yooj yim mus rau ib qho chaw nres tsheb hauv lub chaw tsim hluav taws xob lossis lub Hoobkas rau kev ua haujlwm laser cladding, thiab tsim nyog rau kev kho ntau yam. Lub chaw ua haujlwm feem ntau suav nrog lub tshuab hluav taws xob siab, lub tshuab rau 6-axis, lub tshuab nqus plua plav, coaxial hmoov pub lub taub hau, thiab cov cuab yeej pabcuam xws li cov khoom siv hluav taws xob thiab cua txias uas txhawb nqa lub zog ua haujlwm.
Lub xeev ntawm rotor phau ntawv journal ua ntej kho: qhov chaw hnav ntawm lub rotor raug ntsuas ua ntej kho. Cov phau ntawv journal ntawm bearing Bush tau hnav nyob rau hauv ntau qhov chaw, thiab qhov loj tshaj plaws tau hnav tawm ib tug zawj nrog ib tug tob ntawm 1.3 hli. Qhov saum npoo ntawm lub rotor tsis tuaj yeem ua tau raws li kev ua haujlwm nyab xeeb ntawm chav tsev.
Tom qab kho nrog cov hmoov cladding tshwj xeeb, siv Leeb hardness tester los random sim lub hardness ntawm phau ntawv journal, thiab lub hardness ntawm tag nrho cov cheeb tsam yuav clad yog raws li nyob rau hauv lub rotor puag. Cov txiaj ntsig kev ntsuam xyuas pom tau hais tias qhov kev puas tsuaj ntawm phau ntawv xov xwm tau raug tshem tawm tag nrho, thiab qhov ntev ntawm qhov siab thiab qhov roughness ntawm cov ntawv xov xwm tom qab kho tau tag nrho rov qab los rau qhov kev tsim qauv qub, uas tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm cov kabmob bush thiab phau ntawv journal. . Kev ntsuam xyuas Penetrant tau ua tiav ntawm cov ntawv xov xwm ncej raws li lub Hoobkas qauv ntawm cov khoom siv rotor tshiab. Cov txiaj ntsig ntawm kev ntsuam xyuas pom tau tias cov txheej txheej cladding tsis muaj qhov tsis xws luag xws li slag inclusions, incomplete penetration, cracks, thiab pores, thiab qhov zoo ntawm cladding txheej tau raws li tus txheej txheem. Kev kho cov ntawv xov xwm ntawm lub rotor tau ua tiav ib feem ntawm kev kho thiab tsis muaj kev cuam tshuam rau lwm qhov ntawm lub rotor. Raws li kev tawm tswv yim los ntawm lub tshuab hluav taws xob, lub tshuab hluav taws xob qis qis tau kho thiab muab tso rau hauv kev ua haujlwm. Lub lubricating roj kub, bearing bush kub, thiab ncej vibration ntawm lub chav tsev tag nrho ua tau raws li qhov yuav tsum tau, thiab lub lag luam yog nyob rau hauv zoo.
cov kev xav tau ntawm cov bearing bush thiab phau ntawv journal. Kev ntsuam xyuas Penetrant tau ua tiav ntawm cov ntawv xov xwm ncej raws li lub Hoobkas qauv ntawm cov khoom siv rotor tshiab.
