Lub nplhaib dynamic ntawm thee zeb yog ib qho tseem ceeb, siv rau qhov sib npaug ntawm lub zog centrifugal thiab axial stability ntawm lub rotor. Nyob rau hauv lub niaj hnub pulverized thee ua cov kab ntau lawm, lub luag hauj lwm ntawm dynamic nplhaib ntawm thee zeb yog ntau thiab ntau tseem ceeb. Yog li ntawd, kev tsim khoom zoo thiab siv cov txiaj ntsig ntawm lub nplhaib zeb zeb yog ncaj qha ntsig txog kev ruaj ntseg thiab kev nyab xeeb ntawm pulverized thee ua kab. Hauv Suav teb, kev tsim thiab siv cov thee zeb zoo li qub rings tau suav nrog hauv lub teb chaws tus qauv.
1. Cov kev cai hauv teb chaws
Hais txog cov khoom siv, cov txheej txheem tsim khoom thiab kev ua tau zoo ntawm lub nplhaib zoo li qub ntawm cov thee zeb, Suav teb chaws tus qauv GB / T2933-2017 "Technical Requirements for the Production of movering and static ring for mechanical sealing" tau ua cov ncauj lus kom ntxaws . Ntawm lawv, cov kev cai ntawm cov thee zeb dynamic nplhaib feem ntau suav nrog cov hauv qab no:
1. Cov khoom siv: yuav tsum siv cov khoom siv muaj zog thiab siab hnav, xws li cov hlau tawv tawv, steel-based ceramics, tungsten carbide, thiab lwm yam.
2. Cov txheej txheem ntau lawm: Kev tsim cov nplhaib zoo li qub thiab zoo li qub yuav tsum muaj kev paub txog kev ua haujlwm siab, vuam, kev kho cua sov thiab lwm yam thev naus laus zis los xyuas kom meej cov khoom zoo.
3. Kev ntsuas kev ua tau zoo: feem ntau suav nrog kev ua haujlwm zoo li qub, kev ua haujlwm thermal deformation thiab thermal stability zog, hnav tsis kam ua haujlwm, axial positioning raug thiab lwm yam ntsuas.
2. Cov teeb meem tshwm sim tau ntsib hauv kev siv thiab kev tawm tsam
Nyob rau hauv cov txheej txheem tsim khoom tiag tiag, tej zaum yuav muaj qee qhov teeb meem, xws li lub nplhaib dynamic qhov sib txuam tsis nyob ze, lub nplhaib dynamic kub nce siab dhau lawm, qhov dej ntws zoo li qub yog qhov loj heev. Cov teeb meem no yuav tsis tsuas yog cuam tshuam rau kev ruaj ntseg thiab kev ua tau zoo ntawm cov thee zeb, tab sis kuj tuaj yeem ua rau cov khoom siv tsis ua haujlwm thiab kev nyab xeeb kev nyab xeeb. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau ua raws li cov kev ntsuas kom tsis txhob muaj cov teeb meem no, xws li:
1. Txhim kho qhov kev tshuaj xyuas kom paub tseeb tias qhov tseeb ntawm qhov loj me, cov duab thiab qhov sib npaug ntawm lub nplhaib zoo li qub thiab zoo li qub raws li cov qauv.
2. Ua kom zoo rau cov txheej txheem ntau lawm, txais yuav cov txheej txheem vuam, kev ua thiab kev kho cua sov, kom ntseeg tau tias qhov zoo thiab kev ua haujlwm ntawm cov nplhaib zoo li qub thiab zoo li qub tau lav tag nrho.
3. Txhim kho lubrication thiab txij nkawm, txo qhov hnav thiab thermal deformation ntawm static thiab zoo li qub rings, thiab txhim kho cov kev pab cuam efficiency thiab lub neej ntawm cov khoom.
3. xaus
Lub nplhaib dynamic ntawm thee zeb yog ib feem tseem ceeb ntawm kev ruaj khov ntawm cov thee zeb, thiab nws muaj cov qauv nruj hauv teb chaws rau nws cov khoom tsim thiab siv zoo. Kev saib xyuas yuav tsum tau them nyiaj rau kev tshuaj xyuas, cov txheej txheem tsim khoom thiab kev saib xyuas txhua hnub ntawm cov nplhaib zoo li qub thiab zoo li qub, txhawm rau txo qhov hnav thiab tsis ua haujlwm ntawm cov nplhaib zoo li qub thiab zoo li qub, thiab kom ntseeg tau tias kev ua haujlwm zoo thiab ruaj khov ntawm cov thee zeb.
