Txoj Kev Npaj Thiab Kev Tsim Cov Khoom Siv Hluav Taws Xob

Lub oscillations ntawm turbo-generator teeb yog ncaj qha ntsig txog kev nyab xeeb ntawm turbo-generator teeb, thiab kev nyab xeeb yog qhov txiaj ntsig zoo rau kev lag luam hluav taws xob.Muaj ntau qhov laj thawj rau kev oscillation ntau dhau ntawm chav tsev, nrog rau kev npaj thiab kev tsim khoom, kev ua haujlwm, kev teeb tsa thiab kev saib xyuas.Cov xwm txheej hauv qab no yog qhia raws li.

Turbogenerator rotor yog lub tshuab ua haujlwm siab ceev, yog tias lub rotor centroid thiab qhov chaw rotating tsis sib haum nrog qhov tsis sib xws ntawm lub rotor yuav tsim lub zog centrifugal, lub zog centrifugal ntawm cov kabmob ua rau lub zog zoo siab ua rau lub zog oscillation, Lub zog centrifugal loj heev, lub zog oscillation yuav txawv txav.Yog li ntawd, lub tshuab hluav taws xob turbine rotor nyob rau hauv kev teeb tsa ntawm txhua lub cuab yeej yuav tsum yog theem ntawm cov hniav mus rau qhov kev ntsuas qhov ntsuas, tag nrho cov khoom siv rotor ua tiav ua ntej tawm hauv lub Hoobkas yuav tsum yog tag nrho cov rotor qis thiab kev kub ceev dynamic tshuav, kom xyuas kom meej tias qhov tsis sib npaug ntawm rotor nyob rau hauv ib qho kev tsim nyog.

Hauv cov chaw tsim khoom, lub rotor tsis sib npaug feem ntau yog tshwm sim los ntawm kev siv tshuab ua kom raug tsis txaus thiab tsis zoo ntawm lub cuab yeej, yog li nws yog qhov tsim nyog los txhim kho qhov kev ua haujlwm raug, ua ke los xyuas kom meej qhov zoo ntawm cov cuab yeej, thiab tom qab ntawd kom ntseeg tau tias cov khoom qub. unbalance ntawm rotor tsis loj heev.Tsis tas li ntawd, yog tias kev npaj ntawm chav tsev tsis tsim nyog, nws tseem yuav ua rau lub oscillation ntawm chav tsev.Piv txwv li, nyob rau hauv lub npaj theem, kev xaiv ntawm bearings yog ib qho tseem ceeb heev.Yog tias cov bearings tsis raug xaiv kom raug, qhov me me tsis sib npaug ntawm lub rotor kuj tseem tuaj yeem ua rau loj oscillation ntawm chav tsev vim qhov tsis zoo ntawm cov kabmob tsis zoo.Tej zaum cov roj zaj duab xis muaj pes tsawg leeg tsis zoo thiab nws yooj yim rau induce roj zaj duab xis oscillation.

Kev txhim kho thiab tu

Ntaus thiab kev saib xyuas ntawm chav tsev oscillation yog qhov loj heev, raws li kev paub ntawm on-site unit oscillation, on-site oscillation ntawm ntau chav nyob feem ntau yog tshwm sim los ntawm kev siv tsis raug thiab kev saib xyuas, tej zaum chav tsev oscillation tuaj yeem daws tau los ntawm cov cuab yeej lossis kev saib xyuas hauv ntau li cas.Raws li qhov xwm txheej ntawm thaj chaw, cov ntsiab lus hauv qab no tau qhia txog ntau yam uas muaj kev cuam tshuam loj rau chav nyob oscillations.

1. Bearing elevation

Ob qhov kawg ntawm lub turbine los yog lub tshuab hluav taws xob rotor tau txais kev txhawb nqa los ntawm cov kabmob.Yog tias qhov siab ntawm ob qhov kawg tsis nyob hauv qhov tsim nyog, qhov kev faib tawm ntawm cov kabmob ntawm ob qho kawg yog qhov tsis tsim nyog.Yog li ntawd, thaum lub sij hawm overhaul los yog installation ntawm lub tsev, lub bearing elevation ntawm lub tsev yuav tsum tau ua tib zoo kho raws li cov lus pom zoo ntawm cov chaw tsim tshuaj paus thiab ua ke nrog rau qhov tseeb qhov teeb meem ntawm txhua lub Hoobkas.Vim tias cov ntaub ntawv muab los ntawm cov chaw tsim khoom yog ua raws li lub xeev txias ntawm chav tsev thiab tom qab ntawd suav nrog chav tsev dav dav tom qab cua sov swell, vim tias qhov tseeb ntawm txhua chav tsev tsis zoo ib yam, yog li qhov o tom qab cua sov tsis zoo ib yam. , yog li nws yog ib qho tsim nyog los muab cov xwm txheej tiag tiag ntawm txhua tsob nroj los kho cov kabmob nce siab ntawm chav tsev.

2. Chav tsev Center

Chav tsev yuav tsum suav nrog concentricity ntawm rotor thiab lub tog raj kheej lossis stator, qhov siab ntawm cov kabmob txhawb nqa rotor, concentricity thiab straightness ntawm shafting kev twb kev txuas.Yog hais tias lub concentricity sib txawv ntawm rotor thiab lub tog raj kheej los yog stator loj heev, nws yuav ua rau lub zog ntws excitation, electromagnetic excitation thiab dynamic kev sib tsoo.Yog hais tias qhov kev sib tsoo tshwm sim ntawm lub rotor ncej, lub rotor yuav tsum thermally khoov thiab tsis ruaj tsis khov kev yuam oscillations yuav tshwm sim.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim tshuaj paus ntawm diesel generator nyob rau hauv Suav teb, uas integrates tsim, muab, commissioning thiab txij nkawm ntawm diesel generator teeb.Cov khoom npog Cummins, Perkins , Volvo, Yuchai, Shangchai, Deutz, Ricardo, MTU, Weichai thiab lwm yam nrog lub hwj chim ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab lub chaw thev naus laus zis.
