Hav nyob ntawd! Kuv yog tus xa khoom ntawm Graphite Degassing Rotors, thiab hnub no kuv xav tham txog cov yam ntxwv ntawm kev vibration ntawm cov rotors thaum ua haujlwm.
Ua ntej tshaj, cia peb nkag siab tias Graphite Degassing Rotor yog dab tsi. Nws yog ib qho tseem ceeb ntawm cov hlau - smelting txheej txheem, tshwj xeeb tshaj yog thaum nws los txog rau tshem hydrogen thiab lwm yam impurities los ntawm molten hlau. Koj tuaj yeem tshawb xyuas ntau ntxiv txog nws ntawm no: Graphite Degassing Rotor.
Tam sim no, thaum nws los txog rau kev vibration ntawm cov rotors, nws yog ib lub ntsiab lus nyuaj. Muaj ntau ntau yam uas tuaj yeem cuam tshuam cov yam ntxwv ntawm kev co.
1. Kev sib hloov ceev
Ib qho ntawm qhov pom tseeb tshaj plaws yog qhov kev sib hloov ceev ntawm lub rotor. Raws li lub rotor tig nrawm dua, lub zog centrifugal ua rau nws nce. Ntawm qhov ceev ceev, qhov kev vibration yuav ruaj khov. Tab sis thaum peb crank nce ceev, lub rotor tuaj yeem pib muaj ntau hom kev vibrations. Piv txwv li, ntawm qee qhov ceev ceev, lub rotor tuaj yeem mus rau hauv resonance. Resonance yog qhov xwm txheej uas qhov zaus ntawm lub zog sab nraud (qhov no, qhov kev sib hloov) yog qhov sib txawv ntawm lub rotor. Thaum qhov no tshwm sim, qhov kev vibration amplitude tuaj yeem nce ntxiv. Qhov no tsis zoo rau lub rotor lub neej thiab tuaj yeem cuam tshuam rau kev ua haujlwm degassing.
2. Kev tsis sib haum xeeb
Kev tsis sib haum xeeb yog lwm qhov ua rau muaj kev vibration. Txawm tias me me ntawm qhov tsis sib xws hauv lub rotor tuaj yeem ua rau pom kev vibrations thaum ua haujlwm. Qhov kev tsis sib haum no tuaj yeem tshwm sim los ntawm kev tsim khoom tsis xws luag, hnav tsis sib xws, lossis cov khoom khib nyiab ntawm lub rotor. Thaum lub rotor tsis sib npaug, qhov nruab nrab ntawm qhov loj tsis sib haum nrog lub axis ntawm kev sib hloov. Yog li ntawd, muaj kev sib faib tsis sib luag ntawm cov quab yuam, uas ua rau lub rotor vibrate. Txhawm rau txo qhov kev vibration no, kev saib xyuas tsis tu ncua thiab ntsuas qhov tseem ceeb.
3. Cov kua dej - Cov qauv kev sib tshuam
Lub rotor ua haujlwm nyob rau hauv ib puag ncig molten hlau. Kev sib cuam tshuam ntawm rotor thiab cov hlau molten tuaj yeem ua rau muaj kev vibrations. Qhov ntws ntawm cov hlau molten nyob ib ncig ntawm lub rotor tsim hydrodynamic rog. Cov rog no tuaj yeem tsis ruaj khov, tshwj xeeb tshaj yog tias muaj kev hloov pauv ntawm cov hlau viscosity, kub, lossis ntws tus nqi. Piv txwv li, yog tias cov hlau molten muaj viscosity siab, nws tuaj yeem ua rau rub ntau dua ntawm lub rotor, ua rau muaj kev vibrations. Ntawm qhov tod tes, kev hloov pauv tam sim ntawd hauv tus nqi ntws tuaj yeem ua rau poob siab - zoo li lub zog ntawm lub rotor, uas ua rau muaj kev vibrations.
4. Cov Kabmob kabmob
Cov kabmob uas txhawb nqa lub rotor ua lub luag haujlwm tseem ceeb hauv nws cov yam ntxwv kev co. Hnav - tawm los yog cov kabmob puas tuaj yeem qhia txog kev co ntxiv. Yog tias cov bearings muaj kev tshem tawm ntau dhau lossis yog tias tsis muaj lubrication zoo, lub rotor tuaj yeem muaj kev ua si ntau dua thiab kev txav tsis tu ncua. Qhov no tuaj yeem ua rau muaj kev vibration ntau ntxiv. Kev tshuaj xyuas tsis tu ncua thiab hloov cov bearings yog tsim nyog los khaws cov kev vibration hauv kev kuaj xyuas.
Ntsuas thiab saib xyuas kev vibration
Txhawm rau nkag siab thiab tswj kev vibration ntawm Graphite Degassing Rotors, ntsuas thiab saib xyuas yog qhov tseem ceeb. Muaj ntau yam sensors muaj uas tuaj yeem siv los ntsuas kev vibration. Accelerometers feem ntau yog siv los ntsuas qhov acceleration ntawm rotor lub vibrations. Los ntawm kev txheeb xyuas cov ntaub ntawv acceleration, peb tuaj yeem txiav txim siab qhov zaus thiab amplitude ntawm kev vibrations. Cov ntaub ntawv no tuaj yeem pab peb txheeb xyuas cov teeb meem tshwm sim thaum ntxov. Piv txwv li, yog tias peb pom qhov nce ntawm qhov kev vibration amplitude ntawm ib qho zaus, nws tuaj yeem qhia txog qhov teeb meem loj, xws li cov kabmob tsis ua haujlwm lossis qhov tsis sib xws.
Kev cuam tshuam rau Degassing Efficiency
Lub vibration ntawm lub rotor tuaj yeem cuam tshuam ncaj qha rau kev ua haujlwm degassing. Kev vibrations ntau dhau tuaj yeem cuam tshuam kev tsim thiab faib cov npuas hauv cov hlau molten. Lub hom phiaj ntawm degassing rotor yog tsim cov npuas me me uas tuaj yeem nqus tau cov hydrogen thiab lwm yam impurities hauv cov hlau. Thaum lub rotor vibrates ntau dhau lawm, cov npuas yuav tsis tsim kom zoo lossis tsis tuaj yeem muab faib sib npaug thoob plaws hauv cov hlau molten. Qhov no tuaj yeem ua rau tsis tiav degassing thiab qis dua - cov khoom hlau zoo.
Kev sib piv nrog lwm cov khoom siv graphite
Nws yog qhov nthuav kom sib piv cov yam ntxwv ntawm kev co ntawm Graphite Degassing Rotors nrog rau lwm cov khoom siv graphite siv hauv cov hlau smelting, xws li Graphite npib Casting Pwm thiab Graphite Tube. Graphite npib casting pwm thiab cov raj feem ntau muaj kev ua haujlwm zoo li qub hauv cov hlau - txheej txheem smelting. Lawv feem ntau yog siv los ntim lossis coj cov hlau molten. Yog li, lawv cov teeb meem kev vibration tsis zoo li cov degassing rotors. Txawm li cas los xij, lawv tseem tuaj yeem ntsib qee qhov kev vibrations vim yog nchuav ntawm cov hlau molten lossis cov khoom siv sab nraud.
