Hydro generator yog lub plawv ntawm chaw nres tsheb hydropower.Dej turbine generator chav tsev yog qhov tseem ceeb tshaj plaws cov cuab yeej tseem ceeb ntawm hydropower cog.Nws txoj haujlwm nyab xeeb yog qhov tseem ceeb lav rau hydropower cog kom muaj kev nyab xeeb, muaj txiaj ntsig zoo thiab kev lag luam hluav taws xob tsim hluav taws xob thiab cov khoom siv, uas yog ncaj qha cuam tshuam rau kev nyab xeeb thiab ruaj khov ua haujlwm ntawm daim phiaj hluav taws xob.Kev ua haujlwm ib puag ncig ntawm chav dej turbine generator muaj feem cuam tshuam rau kev noj qab haus huv thiab kev pabcuam lub neej ntawm lub tshuab hluav taws xob.Ntawm no yog cov kev ntsuas coj los txhim kho lub tshuab hluav taws xob ua haujlwm ib puag ncig raws li Xiaowan Hydropower Station.
Roj rejection kho ntawm thrust roj tank
Cov roj rejection ntawm thrust bearing yuav pollute lub hydrogenerator thiab nws cov khoom pab.Xiaowan chav kuj tseem tau plagued los ntawm kev tsis lees txais roj vim nws qhov kev kub ceev.Cov roj tsis kam ntawm Xiaowan thrust bearing yog tshwm sim los ntawm peb lub laj thawj: cov roj creeping ntawm cov ntsia hlau txuas ntawm lub taub hau lub taub hau thiab lub rotor nruab nrab lub cev, cov roj creeping ntawm lub sealing sab sauv ntawm lub thrust roj phiab, thiab dislocation ntawm " t" foob ntawm qhov sib koom ua ke foob ntawm lub thrust roj phiab thiab lub qis annular foob.
Lub tshuab fais fab tau ua tiav sealing grooves ntawm qhov sib koom ua ke ntawm lub taub hau thrust thiab lub rotor centre lub cev, ntsia 8 roj resistant roj hmab strips, thaiv tus pin qhov nyob rau hauv lub rotor center lub cev, hloov tus thawj sab sauv phaj ntawm lub thrust roj phiab nrog. ib tug hu rau roj zawj npog phaj nrog ib tug rov qab sealing sawb, thiab thov sealant rau tag nrho cov kev sib cuag nto ntawm lub split sib koom tes ntawm thrust roj phiab.Tam sim no, cov roj pov phenomenon ntawm thrust roj zawj tau raug daws tau zoo.
Dehumidification transformation ntawm generator cua qhov
Dew condensation nyob rau hauv lub tshuab hluav taws xob cua qhov ntawm underground powerhouse nyob rau hauv South Tuam Tshoj yog ib qho teeb meem tshwm sim thiab nyuaj los daws, uas muaj kev cuam tshuam ncaj qha rau cov rwb thaiv tsev ntawm lub tshuab hluav taws xob stator, rotor thiab nws cov cuab yeej pabcuam.Xiaowan yuav tsum ntsuas kom ntseeg tau tias kev sib khi ruaj khov ntawm lub tshuab hluav taws xob cua qhov thiab sab nraud, thiab ntxiv cov txheej txheem dej rau txhua qhov kav dej hauv lub tshuab hluav taws xob cua qhov.
Tus thawj low-power dehumidifier yog hloov mus rau hauv high-power tag nrho dehumidifier.Tom qab kaw, cov av noo hauv lub tshuab hluav taws xob cua qhov av tuaj yeem tswj tau zoo hauv qab 60%.Tsis muaj condensation nyob rau hauv lub generator cua txias thiab dej system pipelines nyob rau hauv lub cua qhov, uas zoo tiv thaiv corrosion ntawm lub tshuab hluav taws xob stator core thiab cov dej noo ntawm cov khoom siv hluav taws xob thiab cov khoom siv, thiab ua kom lub tshuab hluav taws xob ua haujlwm zoo.
Kev hloov kho ntawm brake ram
Cov plua plav tsim los ntawm tus ram thaum lub tshuab hluav taws xob nres yog qhov muaj kuab paug loj ua rau stator thiab rotor muaj kuab paug.Xiaowan Hydropower chaw nres tsheb hloov tus thawj nres ram nrog non-metallic asbestos dawb plua plav-dawb ram.Tam sim no, tsis muaj plua plav pom tseeb thaum lub tshuab hluav taws xob kaw nres, thiab qhov kev txhim kho tau pom tseeb.
Cov no yog cov kev ntsuas los ntawm Xiaowan Hydropower Station los txhim kho thiab txhim kho lub tshuab hluav taws xob ua haujlwm ib puag ncig.Nyob rau hauv lub xyoo pua kev txhim kho thiab txhim kho kev lag luam ib puag ncig ntawm chaw nres tsheb hydropower, peb yuav tsum tau tshawb fawb thiab tsim nyog tsim cov txheej txheem txhim kho raws li qhov xwm txheej tshwj xeeb, uas tsis tuaj yeem hais dav dav.
