Kev Sib Tw Ua Haujlwm Zoo Tshaj Plaws: Cov Tswv Yim Tseem Ceeb thiab Phau Ntawv Qhia Txog Kev Xaiv Cov Bearing Sliding

 

Hauv cov tshuab kis tau tus mob, radial slidingcov kabmobyog cov khoom tseem ceeb uas txhawb nqa cov ncej tig. Qhov kev xaiv ntawm lawv qhov kev xav tau ncaj qha cuam tshuam rau qhov ruaj khov thiab lub neej ntev ntawm cov khoom siv. Ntsib nrog ntau yam kev ua haujlwm sib txawv, peb yuav ua li cas txiav txim siab kom tsis txhob ua haujlwm ntau dhau lossis ua haujlwm ntau dhau?

 

Tsab xov xwm no muab ib txoj hauv kev xaiv raws li peb yam: hom qauv, kev sib phim ntawm cov txheej txheem ua haujlwm, thiab cov khoom siv.

 

1. Kev faib tawm los ntawm cov qauv kom phim cov kev cai teeb tsa thiab kev saib xyuas

 

Kev swbcov kabmobfeem ntau yog muab faib ua peb pawg:

 

Kev Sib Koom Ua Ke: Me me thiab pheej yig, tsim nyog rau cov khoom thauj me me, qhov ceev qis, thiab cov ntawv thov uas xav tau kev sib dhos thiab rhuav tshem tsawg zaus, xws li cov cav me me thiab cov khoom siv hauv tsev.

 

Faib: Yooj yim rau nruab thiab tswj hwm axial positioning, siv dav hauv cov khoom siv nruab nrab mus rau loj, xws li gearboxes thiab compressors, xav tau kev saib xyuas tsis tu ncua.

 

Kev sib dhos tus kheej: Nruab nrog lub luag haujlwm sib dhos tus kheej, nws them rau qhov kev hloov pauv ntawm tus ncej lossis kev teeb tsa sib txawv. Nws yog qhov tsim nyog rau cov ncej ntev lossis cov qauv yooj yim deformed thiab feem ntau pom muaj nyob rau hauv cov tshuab hnyav thiab cov tshuab tsav nkoj hauv hiav txwv.

 

2. Siv cov kab nkhaus tshwj xeeb los txheeb xyuas sai saikev coj uahom

 

Hauv kev xyaum ua engineering, feem ntau siv cov kab nkhaus xaiv cov kabmob rau kev tshuaj xyuas ua ntej. Daim ntawv qhia no siv qhov ceev ntawm phau ntawv xov xwm ua kab rov tav thiab qhov hnyav ib chav tsev thaj tsam ua kab ntsug los faib cov kab sib txawv ntawm cov kabmob sib txawv. Piv txwv li, rau qhov ceev qis thiab hnyav, cov kabmob uas muaj kua nplaum yog qhov zoo dua; rau qhov ceev nruab nrab thiab qhov hnyav nruab nrab, cov kabmob sib cais nrog cov kua nplaum ib nrab yog qhov kev xaiv ntau; rau qhov ceev siab thiab lub teeb, cov kabmob uas muaj tus kheej nplaum lossis cov kabmob yas tuaj yeem siv los txo qhov sib txhuam thiab qhov kub nce. Los ntawm kev sab laj nrog lub rooj (xws li cov ntawv qhia xaiv hauv cov qauv kev lag luam), cov neeg tsim qauv tuaj yeem tshem tawm cov hom tsis tsim nyog sai sai, txhim kho kev xaiv zoo.

 

3. Kev sib piv ntawm cov khoom siv ua haujlwm txiav txim siab qhov kev ntseeg tau ntawm kev ua haujlwm

 

Txawvkev coj uaCov ntaub ntawv siv tau rau ntau qhov chaw ua haujlwm sib txawv: Cov kabmob hmoov metallurgy: Lawv yog cov roj uas nws tus kheej lubricating thiab tsim nyog rau cov chaw tsis muaj roj lossis cov roj tsawg, tab sis lawv muaj kev tiv thaiv tsis muaj zog thiab feem ntau siv rau hauv cov khoom siv thauj khoom me me, tsis tu ncua. Cov kabmob yas (xws li POM thiab PTFE-based bearings): Lawv yog cov tiv taus corrosion, suab nrov tsawg, thiab tsis tas yuav tsum tau lubrication, tab sis muaj kev ruaj khov thermal tsis zoo thiab tsim nyog rau cov chaw noo noo, huv si, lossis kev ua zaub mov. Cov kabmob Babbitt-lined: Lawv muaj peev xwm thauj khoom muaj zog thiab ua raws li qhov zoo heev, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv thauj khoom hnyav, cov khoom siv ceev qis. Txawm li cas los xij, lawv kim dua thiab xav tau lub tshuab lubrication.

 

Kev swbkev coj uaKev xaiv tsis yog txiav txim siab los ntawm ib qho parameter xwb; nws yog kev sib pauv dav dav ntawm hom qauv, cov xwm txheej ua haujlwm, thiab cov khoom siv. Cov neeg tsim qauv raug qhia kom siv cov ntawv xaiv los ua qhov kev tshuaj xyuas ua ntej raws li qhov ceev, cov khoom thauj, qhov chaw txwv, thiab cov voj voog txij nkawm. Tom qab ntawd, lawv yuav tsum sib piv cov khoom siv kom thaum kawg txiav txim siab qhov kev daws teeb meem zoo tshaj plaws. Rau cov pib tshiab, kev paub txog cov txheej txheem no tuaj yeem txhim kho kev tsim qauv zoo thiab kev ntseeg siab.
