Bearings yog qhov tseem ceeb tshaj plaws txhawb nqa ntawm cov motors.Nyob rau hauv ib txwm muaj xwm txheej, thaum kub ntawm lub cev muaj zog bearings tshaj 95 ° C thiab qhov kub ntawm cov zawv zawg bearings tshaj 80 ° C, cov bearings yog overheated.
Cov kabmob overheating thaum lub cev muaj zog khiav yog qhov ua txhaum ntau, thiab nws qhov ua rau muaj ntau yam, thiab qee zaum nws nyuaj rau kev kuaj mob kom raug, yog li muaj ntau qhov kev kho mob tsis raws sijhawm, qhov tshwm sim feem ntau yog kev puas tsuaj rau lub cev muaj zog, ua lub cev muaj zog Lub neej luv luv, uas cuam tshuam rau kev ua haujlwm thiab kev tsim khoom.Sau cov xwm txheej tshwj xeeb, yog vim li cas thiab txoj kev kho mob ntawm lub cev muaj zog bearing overheating.
1. Vim li cas thiab txoj kev kho mob rau overheating ntawm lub cev muaj zog bearings:
1. Lub dov bearing yog ntsia tsis raug, qhov haum haum yog nruj dhau los yog xoob dhau.
Kev daws teeb meem: Kev ua haujlwm ntawm dov bearings nyob ntawm tsis yog tsuas yog nyob rau ntawm qhov raug ntawm cov kabmob nws tus kheej xwb, tab sis kuj yog nyob ntawm qhov raug qhov tseeb, qhov kev kam rau siab thiab nto roughness ntawm lub ncej thiab lub qhov uas phim nws, xaiv haum thiab seb lub installation puas yog. los tsis.
Nyob rau hauv dav dav kab rov tav motors, zoo-assembled dov bearings tsuas yog dais radial kev nyuaj siab, tab sis yog hais tias qhov haum ntawm lub puab nplhaib ntawm cov kabmob thiab cov ncej yog nruj heev, los yog qhov haum ntawm lub nplhaib sab nrauv ntawm cov kabmob thiab lub hau kawg yog nruj heev. , uas yog, thaum lub siab ntev dhau lawm, ces tom qab sib dhos Lub bearing clearance yuav dhau los ua me me, qee zaum txawm nyob ze rau xoom.Kev sib hloov tsis hloov pauv li qhov no, thiab nws yuav tsim kom muaj cua sov thaum ua haujlwm.
Yog tias qhov haum ntawm cov kabmob puab lub nplhaib thiab cov ncej yog xoob dhau, lossis cov kabmob sab nraud thiab lub hau kawg yog xoob dhau, ces cov kabmob puab lub nplhaib thiab cov ncej, lossis cov kabmob sab nraud thiab lub hau kawg, yuav tig cov txheeb ze. rau ib leeg, ua rau muaj kev sib txhuam thiab kub, ua rau cov kabmob tsis ua haujlwm.overheat.Feem ntau, qhov kam rau ua ntawm lub puab txoj kab uas hla ntawm bearing puab nplhaib raws li ib tug siv ib feem yog tsiv nyob rau hauv lub zero kab nyob rau hauv tus txheej txheem, thiab ib tug kam rau ua ntawm tib ncej thiab lub puab nplhaib ntawm cov bearings tsim ib tug haum uas yog ntau nruj dua. tshaj qhov uas tsim nrog lub dav siv qhov.
2. Kev xaiv tsis tsim nyog ntawm cov roj lubricating lossis kev siv tsis raug thiab kev saib xyuas, cov roj lubricating tsis zoo, los yog sib xyaw nrog cov plua plav thiab impurities tuaj yeem ua rau cov kabmob kub.
Kev daws: Ntxiv roj ntau dhau los yog tsawg dhau kuj yuav ua rau cov kabmob kom sov, vim tias thaum muaj roj ntau dhau, yuav muaj kev sib txhuam ntawm qhov sib hloov ntawm cov kabmob thiab cov roj, thiab thaum muaj roj ntxiv. tsawg dhau, dryness yuav tshwm sim Kev sib txhuam thiab cua sov.Yog li, cov roj yuav tsum tau hloov kho kom nws yog li 1/2-2/3 ntawm qhov chaw ntim ntawm cov kabmob chamber.Cov roj lubricating tsis zoo lossis tsis zoo yuav tsum tau muab ntxuav thiab hloov nrog cov roj lubricating uas tsim nyog.
3. Qhov sib txawv ntawm axial ntawm cov kabmob sab nrauv ntawm lub cev muaj zog thiab lub voj voog sab nraud ntawm cov kabmob dov yog me dhau.
Kev daws: Cov motors loj thiab nruab nrab feem ntau siv cov pob bearings ntawm qhov kawg uas tsis yog ncej.Cov menyuam bearings yog siv thaum kawg ntawm lub ncej txuas ntxiv, yog li ntawd thaum lub rotor yog rhuab thiab nthuav, nws muaj peev xwm elongate dawb do.Txij li thaum ob qho tag nrho ntawm lub tshuab me me siv cov pob bearings, yuav tsum muaj qhov sib txawv ntawm cov kabmob sab nrauv thiab lub nplhaib sab nraud ntawm cov kabmob, txwv tsis pub, cov kabmob tuaj yeem ua kom sov vim yog thermal elongation ntau dhau ntawm cov kev taw qhia axial.Thaum qhov tshwm sim no tshwm sim, sab pem hauv ntej lossis sab nraub qaum yuav tsum tau muab tshem tawm me ntsis, lossis ib daim ntawv nyias nyias yuav tsum muab tso rau ntawm lub hau npog thiab lub hau kawg, kom muaj qhov chaw txaus tsim ntawm cov kabmob sab nraud ntawm ib qho kawg. thiab lub nplhaib sab nraud ntawm cov kabmob.Clearance.
4. Qhov kawg npog los yog lub hau npog ntawm ob sab ntawm lub cev muaj zog tsis tau teeb tsa kom zoo.
Kev daws: Yog tias qhov kawg npog lossis cov kabmob npog ntawm ob sab ntawm lub cev muaj zog tsis tau nruab rau hauv qhov sib npaug lossis cov seams tsis nruj, cov khoom yuav sib txawv ntawm txoj kev khiav thiab tig los ua kom muaj cua sov.Lub kaus mom kawg lossis cov kabmob ntawm ob sab yuav tsum tau muab rov qab tiaj tus, thiab sib npaug sib npaug thiab kho nrog bolts.
5. Cov npas, cov menyuam, cov nplhaib sab hauv thiab sab nraud, thiab cov pob tawb raug hnyav hnyav los yog hlau tev tawm.
Kev daws: Cov kabmob yuav tsum tau hloov lub sijhawm no.
6. Kev sib txuas tsis zoo rau kev thauj khoom siv tshuab.
Cov laj thawj tseem ceeb yog: kev sib dhos tsis zoo ntawm kev sib txuas, kev rub ntau dhau ntawm txoj siv, tsis sib haum nrog lub axis ntawm lub tshuab thauj khoom, txoj kab uas hla me me ntawm lub rubey, deb dhau ntawm cov kabmob ntawm lub pulley, ntau axial lossis radial load, thiab lwm yam. .
Kev daws: Kho qhov kev sib txuas tsis raug kom tsis txhob muaj qhov txawv txav ntawm cov kabmob.
7. Cov ncej yog khoov.
Kev daws: Lub sijhawm no, lub zog ntawm cov kabmob tsis yog lub zog radial ntshiab, uas ua rau cov kabmob kub.Sim ua kom ncaj cov ncej khoov lossis hloov nrog cov kabmob tshiab
2. Yuav ua li cas tiv thaiv lub cev muaj zog los ntawm overheating?
Nws tuaj yeem txiav txim siab faus qhov ntsuas qhov ntsuas kub nyob ze ntawm cov kabmob, thiab tom qab ntawd tiv thaiv cov kabmob los ntawm kev tswj xyuas Circuit Court.Download Feem ntau, lub cev muaj zog ntsuas qhov ntsuas kub (xws li lub thermistor) nyob rau hauv lub cev muaj zog, thiab tom qab ntawd 2 cov xov hlau tawm los ntawm sab hauv los txuas rau tus tiv thaiv tshwj xeeb, thiab tus tiv thaiv xa cov hluav taws xob tas li 24V, thaum lub cev muaj zog thaum lub overheating ntau tshaj li tus nqi ntawm tus tiv thaiv, nws yuav mus thiab ua si lub luag hauj lwm tiv thaiv.Tam sim no, feem ntau cov tuam txhab tsav tsheb hauv lub tebchaws siv txoj kev tiv thaiv no.
