Kev siv tshuab laser cladding yog qhov siv tau zoo heev hauv kev saib xyuas lub cev muaj zog

Thaum lub sijhawm saib xyuas thiab kho cov cav, cov khoom feem ntau tsis tsim nyog vim yog kev ua haujlwm ntev, hnav, lossis sib dhos tsis raug. Piv txwv li, lub rooj zaum ntawm lub cev muaj zog me dua vim yog hnav, thiab lub chamber bearing loj dua vim yog xoob. Rau cov chaw saib xyuas thiab kho cov kws tshaj lij, cov txheej txheem kho hauv zos yog qhov tseem ceeb tshwj xeeb vim tias lawv tsis muaj peev xwm ua tiav thiab hloov cov khoom. Cov txheej txheem kho ib txwm muaj xws li txhuam plating, surfacing, thiab txias vuam tau siv dav, tab sis txhua tus muaj nws cov kev txwv. Nyob rau hauv xyoo tas los no, laser cladding technology tau siv ntau dua hauv kev kho cov khoom siv cav vim nws qhov kev ua tau zoo heev thiab kev hloov pauv tau. Tsab xov xwm no yuav qhia txog cov ntsiab cai, cov yam ntxwv ntawm cov txheej txheem, qhov zoo, thiab kev siv cov txheej txheem ntawm laser cladding technology hauv kev saib xyuas lub cev muaj zog.

1. Cov yam ntxwv ntawm cov txheej txheem ntawm laser cladding

Cov thev naus laus zis laser cladding muaj peev xwm muab faib ua ob hom: synchronous hmoov pub cladding thiab pre-set hmoov cladding, nyob ntawm txoj kev ua. Nyob rau hauv xyoo tas los no, qhov tshwm sim ntawm ultra-high-speed laser cladding (EHLA) thev naus laus zis tau txhim kho qhov ua tau zoo thiab zoo ntawm cov txheej txheem no.

Kev Siv Laser Cladding Ib Txwm Muaj Piv Rau Kev Siv Laser Cladding Uas Muaj Kev Kub Ceev Heev

Cov txheej txheem laser ceev ceev heev tuaj yeem tsim cov txheej txheej sib xws dua vim nws lub pas dej molten tsis tob thiab qhov txias sai heev, thiab muaj kev ntxhov siab tsawg dua ntawm cov substrate, uas tuaj yeem tiv thaiv kev hloov pauv ntawm cov khoom ua haujlwm. Nws yog qhov tshwj xeeb tshaj yog rau kev kho cov chaw sib phim meej xws li cov kabmob lub cev muaj zog thiab cov ntawv xov xwm.

2. Cov Kev Siv Laser Cladding Hauv Kev Kho Lub Cev Muaj Zog

Hauv kev kho lub cev muaj zog, cov thev naus laus zis laser cladding feem ntau yog siv rau hauv cov xwm txheej hauv qab no:

1) Kho cov bearings ntawm lub cev muaj zog

Tom qab ua haujlwm ntev, cov kabmob ntawm lub cev muaj zog feem ntau txo qhov loj vim yog hnav. Cov txheej txheem ib txwm muaj xws li txhuam plating lossis thermal spraying muaj lub zog sib txuas qis, thaum cladding yooj yim ua rau deformation. Laser cladding tuaj yeem clad raug cov khoom siv alloy siab-hardness (xws li nickel-based lossis cobalt-based alloys) rau ntawm cov khoom hnav, rov qab kho qhov loj me thiab txhim kho kev tiv thaiv hnav.

2) Kho qhov hnav ntawm lub chamber bearing

Lub chamber bearing loj dua vim yog lub bearing khiav tawm lossis sib dhos tsis raug. Cov txheej txheem ib txwm muaj xws li ntxig cov tes tsho lossis cladding muaj lub voj voog kho ntev thiab kim heev. Laser cladding tuaj yeem ncaj qha cladding ib txheej hlau rau ntawm qhov chaw hnav, thiab tom qab ntawd rov qab kho qhov loj me qub los ntawm kev ua haujlwm zoo, ua rau lub voj voog txij nkawm luv dua.

3) Kho qhov puas tsuaj hauv zos rau phau ntawv xov xwm, qhov tseem ceeb, thiab lwm yam.

Lub tshuab hluav taws xob, qhov tseem ceeb, thiab lwm yam yuav raug kev puas tsuaj hauv zos vim muaj kev cuam tshuam lossis qaug zog. Laser cladding tuaj yeem kho lawv kom raug, zam qhov xav tau hloov tag nrho cov khoom ntawm lub ncej thiab txo cov nqi.

3. Cov txiaj ntsig ntawm laser cladding dua li cov txheej txheem kho ib txwm muaj

Piv rau cov txheej txheem kho ib txwm muaj (xws li kev vuam overlay, txhuam plating, thiab vuam txias), laser cladding muaj cov txiaj ntsig tseem ceeb hauv qab no:

Lub zog sib txuas siab: Kev sib txuas ua ke ntawm cov hlau ua kom muaj kev sib txuas zoo ntawm cov txheej cladding thiab cov substrate, tiv thaiv nws kom tsis txhob tev tawm.

Kev Cuam Tshuam Kub Tsawg: Cov cua sov tsawg txo qhov kev hloov pauv ntawm cov khoom siv, ua rau nws tsim nyog rau kev kho cov khoom ua haujlwm raug.

Kev Sib Tw Dav Dav ntawm Cov Khoom Siv: Nws tuaj yeem npog ntau yam khoom siv, suav nrog cov hlau tsis xeb, cov hlau nickel-based, thiab tungsten carbide, kom tau raws li ntau yam kev ua haujlwm.

Kev Kho Kom Zoo: Kev tswj hwm theem micron tau ua tiav, txo cov kev siv zog ua haujlwm tom qab.

Ib puag ncig zoo thiab ua haujlwm tau zoo: Tsis muaj kuab paug electroplating, siv cov hmoov ntau, thiab ua raws li cov qauv tsim khoom ntsuab.

4. Kev Txwv thiab Kev Txhim Kho Yav Tom Ntej ntawm Laser Cladding

Txawm hais tias muaj qhov zoo ntawm kev siv tshuab laser cladding, nws tseem muaj qee qhov kev txwv:

Tus nqi khoom siv siab: Cov txheej txheem laser cladding kim heev, ua rau muaj kev xav tau siab rau kev lag luam ntawm cov chav kho.

Cov Kev Cai Tswjfwm Nruj: Cov txheej txheem Laser yuav tsum tau tswj hwm kom meej, txwv tsis pub cov qhov tsis zoo xws li porosity thiab tawg yuav tshwm sim.

Cov Kev Txwv Loj Siv Tau: Kev kho cov khoom loj heev (xws li cov rotors ntawm lub cev muaj zog hnyav) tseem vam khom cov txheej txheem ib txwm muaj.

Yav tom ntej, nrog kev siv dav dav ntawm cov khoom siv laser cladding ntse thiab nws txoj kev koom ua ke nrog 3D luam ntawv kho tshuab, laser cladding yuav siv dav dua hauv kev kho lub cev muaj zog thiab tej zaum yuav dhau los ua cov thev naus laus zis tseem ceeb rau kev tsim kho lub cev muaj zog dua.

5. Xaus Lus

Kev siv tshuab laser cladding, nrog nws qhov kev ua haujlwm siab, kev cuam tshuam thermal qis, thiab cov khoom sib txuas zoo heev, qhia tau tias muaj peev xwm kho cov khoom siv lub cev muaj zog. Piv rau kev vuam overlay thiab txhuam plating ib txwm muaj, nws ua kom rov qab zoo dua qub thiab txhim kho kev hnav thiab kev tiv thaiv corrosion ntawm cov khoom. Txawm hais tias tam sim no tus nqi khoom siv siab thiab cov txheej txheem teeb meem, nrog rau kev nce qib ntawm thev naus laus zis, laser cladding yuav tsum dhau los ua kev daws teeb meem kho hauv kev lag luam txij nkawm lub cev muaj zog, muab kev ntseeg siab rau kev ua haujlwm ntev thiab ruaj khov ntawm cov cev muaj zog.
