1.4 Rotational yooj thiab vibration suab nrov ntawm cov khoom tiav cov kabmob
Txij li thaum cov kabmob yog raug rau siab thiab kev ntxhov siab thaum lub sijhawm ua haujlwm, yog li muaj cov yam ntxwv siab thiab txawm hardness, siab elastic txwv thiab kuj siab compressive zog yuav tsum tau rau cov khoom tiav bearing.Yog li ntawd, thaum lub sij hawm tig, ib tug benign bearing yuav tsum ua hauj lwm briskly yam tsis muaj blockage.Txhawm rau kom muaj txiaj ntsig zoo ntawm kev co suab nrov ntawm cov kabmob, cov kev ntsuas sib xws yuav tsum tau ua rau kev co suab nrov ntawm cov kabmob uas tsim los ntawm kev teeb tsa tsis raug.
1.5 Residual sib nqus siv ntawm cov khoom tiav cov kabmob
Residual magnetic intensity yog ib qho ntawm cov khoom soj ntsuam ntawm cov khoom tiav cov kabmob vim tias yuav muaj cov hlau nplaum seem thaum lub sijhawm ua haujlwm.Qhov no yog vim hais tias ob lub electromagnetic cores yuav tsum tsis muaj kev sib raug zoo, yog li lawv yuav tsum ua haujlwm ntawm nws tus kheej.Nyob rau hauv lub meantime, cov tub ntxhais ntawm electromagnetic kauj yog kho raws li ib tug neeg kho tshuab tivthaiv, whereas lub kauj yog tsis.
1.6 Nto zoo ntawm cov khoom lag luam tiav
Nto zoo kuj yog ib qho ntawm cov khoom soj ntsuam ntawm cov khoom lag luam tiav, yog li ntawd, kev soj ntsuam zoo yuav tsum tau ua raws li qhov roughness, ntau yam tawg, ntau yam kev raug mob thiab zoo, thiab lwm yam. Rau cov bearings uas tsis yog-conforming, lawv siv tsis tau, tab sis yuav tsum xa rov qab mus rau cov chaw tsim khoom rau kev rov ua haujlwm dua.Thaum siv, lawv yuav ua rau muaj ntau yam kev raug mob rau cov khoom siv.
1.7 Hardness ntawm cov khoom tiav cov kabmob
Hardness ntawm bearing yog lub ntsiab zoo qhia.Txij li thaum lub pob steel rotates nyob rau hauv spherical channel, nws kuj muaj ib tug tej yam centering nyhuv nyob rau tib lub sij hawm, yog li ntawd, cov bearings uas tsis yog-conforming hardness yuav tsum tsis txhob muab tso rau hauv kev siv.
2.1 Txoj kev cai
Kev tshuaj xyuas cov txheej txheem ntawm cov khoom lag luam tiav yog cov txheej txheem kev tshuaj xyuas phau ntawv, qhov twg, kev ua haujlwm ntawm cov kabmob hauv cov cuab yeej siv tshuab yuav raug txiav txim siab los ntawm qee tus neeg ua haujlwm paub txog kov tes lossis mloog pob ntseg.Txawm li cas los xij, nrog txoj kev loj hlob sai ntawm kev lag luam kev lag luam niaj hnub no, muaj ntau yam tsis zoo ntawm kev siv cov txheej txheem ib txwm muaj, thiab lub sijhawm no, cov kev ua yuam kev tsis tuaj yeem raug cais tawm raws sijhawm raws li phau ntawv qhia.Yog li ntawd, txoj kev lig kev cai tsis tshua muaj siv niaj hnub no.
2.2 Cov txheej txheem ntsuas kub
Kev ntsuas kub ntawm cov bearings yog ib txoj hauv kev siv cov khoom siv kub-rhiab los ua qhov tseeb ntawm kev pabcuam lub neej ntawm cov kabmob thiab txiav txim siab qhov tsis raug.Kev ntsuas kub ntawm cov bearings yog rhiab heev rau cov kev hloov hauv load, ceev thiab lubrication, thiab lwm yam ntawm bearings, thiab feem ntau yog siv nyob rau hauv kev sib hloov ib feem ntawm machinery khoom, ua si lub luag hauj lwm tseem ceeb ntawm bearing, fixation thiab lubrication.Yog li ntawd, txoj kev kuaj ntsuas kub yog ib txoj hauv kev.
2.3 Acoustic emission tshuaj xyuas txoj kev
Cov bearings yuav muaj kev qaug zog thiab tsis ua haujlwm tom qab lub sijhawm ua haujlwm ntev, uas yog tshwm sim los ntawm qhov pits ntawm cov kabmob sib cuag.Acoustic emission tshuaj xyuas txoj kev yog los txiav txim qhov xwm txheej ntawm cov khoom tiav los ntawm kev sau cov cim no.Cov qauv no tau nruab nrog ntau qhov zoo xws li lub sijhawm luv luv rau lub suab nrov emission teeb liab, kev cuam tshuam sai ntawm kev ua tsis tiav, lub sijhawm ua haujlwm tiag tiag thiab qhov chaw ntawm cov ntsiab lus txhaum, thiab lwm yam, yog li ntawd, acoustic emission technology tau dav siv hauv kev tshuaj xyuas cov kabmob.
2.4 Txoj kev tshuaj xyuas lub zog yoj
Kev soj ntsuam yoj yoj txoj kev yog ib txoj hauv kev tseem ceeb rau kev ua txhaum thaum ntxov ntawm cov khoom lag luam tiav.Thaum lub sijhawm ua haujlwm, txij li lub pob khiav, lub tawb thiab lwm qhov ntawm cov kabmob muaj kev puas tsuaj tas li, yog li ntawd, nws tau dhau los ua ib txoj hauv kev tshuaj xyuas cov kabmob los ntawm kev tau txais lub cim hloov pauv los txheeb xyuas thiab txiav txim cov ntaub ntawv no.
2.5 Vibration Diagnosis Technology
Thaum lub sij hawm ua hauj lwm, lub sij hawm mem tes teeb liab yog tus yuam sij rau kev soj ntsuam cov bearings los ntawm kev vibration diagnostic technology.Kev tawg ntawm cov kabmob feem ntau yog vim muaj kev phom sij zais los ntawm kev ua haujlwm tsis zoo, qhov twg, thaum siv cov khoom siv siab, cov chaw puas yuav muaj cov kab nrib pleb thiab tawg, yog li ua rau tawg ntawm bearings.Kev ua txhaum ntawm cov khoom tiav bearing yog txiav txim los ntawm kev txais thiab kev tsom xam ntawm cov teeb liab.Nws yog qhov yooj yim heev los siv txoj kev no los tshuaj xyuas cov cuab yeej siv thiab kev ua haujlwm, yog li ntawd, qhov no kuj yog ib qho ntawm cov qauv kev tshuaj xyuas cov khoom tiav cov kabmob.
3.1 Cov khoom soj ntsuam zoo
Txij li cov bearings muaj ntau ntau yam thiab ntau yam sib txawv lub hom phiaj, thiab txhua tus yam ntxwv zoo kuj tseem muaj qhov sib txawv ntawm cov bearings, yog li ntawd, nws yog ib qho tseem ceeb tshwj xeeb los ua kom zoo tshaj plaws ntawm kev ua haujlwm ntawm cov khoom kuaj xyuas cov khoom tiav.Raws li peb txhua tus paub, kev ntsuas kev ua haujlwm nws tus kheej yog qhov kev sim ua kom puas tsuaj, yog li ntawd, yuav muaj qee yam kev puas tsuaj rau cov kabmob thaum ua cov khoom tuaj xyuas, kev tshuaj xyuas cov txheej txheem thiab kev tshuaj xyuas cov khoom tiav.Thaum ua cov txheej txheem tshawb fawb thiab kev soj ntsuam zoo, ua cov yam ntxwv zoo rau ib yam khoom tshwj xeeb, thiab teeb tsa qhov ntsuas qhov tseeb, qhov yuav tsum tau ua kom raug thiab ntsuas tus nqi ntawm cov khoom kuaj xyuas yuav tsum tau muab rau hauv kev txiav txim siab.Nws tuaj yeem paub los ntawm cov kev xav tau yooj yim rau kev tsom xam cov teeb liab uas, lub teeb liab vibration yuav tsum suav nrog lub sij hawm sau qhov taw qhia thiab qhov ntsuas qhov zaus, thiab cov kev cuam tshuam ntawm kev ua cov txheej txheem thiab ntau yam txheej txheem ntawm ntau yam zoo ntawm cov khoom yuav tsum to taub.
3.2 Kev soj ntsuam zoo
Hais txog txoj kev loj hlob thiab cov kev cai ntawm kev lag luam bearing nyob rau hauv Suav teb tam sim no, ib tug series ntawm kev soj ntsuam cov txheej txheem yuav tsum tau nyob rau hauv thiaj li yuav xaiv qhov zoo tshaj plaws tswvyim los ntawm ntau yam tsim nyog schemes.Nyob rau hauv daim ntawv no, cov khoom soj ntsuam zoo ntawm cov khoom tiav cov kabmob muaj cov ntsiab lus piav qhia, suav nrog cov qauv tshuaj xyuas zoo, cov khoom tshuaj xyuas zoo thiab cov txheej txheem tshuaj xyuas zoo.Cov kev xav tau ntawm kev tsim cov kabmob kev lag luam hauv Suav teb tuaj yeem ua tau tsuas yog los ntawm kev ua kom muaj txiaj ntsig thiab hloov kho tas li.
Nrog rau kev loj hlob sai ntawm kev tshawb fawb thiab thev naus laus zis nrog rau kev txhim kho tib neeg txoj kev ua neej nyob hauv Suav teb, ntau hom tshuab muaj nyob nrog tib neeg lub neej, ntawm cov kabmob ua lub luag haujlwm tseem ceeb.Kev ua tau zoo ntawm cov kabmob tuaj yeem lav tau yog tias ntim cov khoom qub ntawm cov kabmob tsis zoo.Txij li cov kabmob feem ntau yog siv los ua lub tshuab ua haujlwm rau kev txhawb nqa kev sib hloov axis, yog li ntawd, thaum lub sijhawm ua haujlwm, nws yuav dais radial thiab axial loads los ntawm axis, thiab tig nrog axis ntawm kev kub ceev.Tam sim no, feem ntau yog ob txoj kev tshuaj xyuas ntawm cov khoom lag luam tiav: ib puas feem pua kev tshuaj xyuas thiab kev soj ntsuam kuaj.Cov txheej txheem kev txiav txim siab sib txawv raws li kev ua tau zoo ntawm cov tshuab, qhov tseem ceeb thiab lub sijhawm tshuaj xyuas, thiab lwm yam. Cov khoom kuaj xyuas cov khoom zoo yog txiav txim siab raws li cov yam ntxwv zoo, tab sis txhua yam khoom yog nruab nrog cov yam ntxwv zoo hauv ntau yam.Txhawm rau muab kev ua si siab tshaj plaws rau kev ua haujlwm ntawm cov kabmob, cov kabmob yuav tsum tau tshuaj xyuas tsis tu ncua raws li kev tiv thaiv kev tiv thaiv.
