Lub tshuab hluav taws xob teeb yog cov cuab yeej tseem ceeb ntawm Hydropower chaw nres tsheb

Lub zog yog lub hauv paus ntawm kev txhim kho kev sib raug zoo thiab kev txhawb nqa thiab lub zog ntawm kev loj hlob ntawm kev lag luam hauv tebchaws.Lub zog tsis yog tsuas yog cuam tshuam nrog tib neeg txoj kev loj hlob, tab sis kuj plays lub luag hauj lwm irreplaceable nyob rau hauv kev sib raug zoo thiab kev lag luam kev loj hlob.Nyob rau niaj hnub no lub zog noj qauv nyob rau hauv Tuam Tshoj, fossil zog tseem tseem ceeb, thiab qhov kev tsis sib haum xeeb ntawm lub zog txwv thiab kev xav tau yog nce zuj zus, uas tau dhau los ua ib qho kev txwv tsis pub muaj kev sib raug zoo thiab kev lag luam.Hauv qhov xwm txheej no, raws li hom hluav taws xob tauj dua tshiab, hydropower nkag mus rau theem keeb kwm thiab nyob hauv txoj haujlwm tseem ceeb.Kev siv hluav taws xob thoob ntiaj teb xav tias yuav nce 1.5 npaug ntawm 1174.3 billion tons hauv 2010 txog 175.17 billion tons hauv 2035. Fossil roj noj tam sim no suav txog 90 feem pua.Kev hloov pauv hauv cov peev txheej ntuj thiab lub zog huv yuav tsum tau tshawb nrhiav ntxiv vim tias cov roj fossil tsis tuaj yeem txuas ntxiv thiab lawv cov kev cuam tshuam ib puag ncig thiab kev noj qab haus huv.Hydropower suav txog 15% ntawm lub ntiaj teb cov khoom siv hluav taws xob thiab yog lub hauv paus tseem ceeb ntawm kev siv hluav taws xob txuas ntxiv thiab muaj zog.

Lub turbine yog lub plawv ntawm txhua qhov chaw nres tsheb hydropower, hloov lub peev xwm ntawm dej mus rau hauv lub zog txhua yam.Lub tshuab hluav taws xob hydro-generator yog cov cuab yeej tseem ceeb ntawm chaw nres tsheb hydropower, thiab nws txoj haujlwm nyab xeeb yog qhov tseem ceeb lav kom ntseeg tau tias muaj kev nyab xeeb, muaj txiaj ntsig zoo thiab kev lag luam hluav taws xob thiab hluav taws xob ntawm qhov chaw nres tsheb hydropower.Nws yog ncaj qha ntsig txog kev nyab xeeb thiab ruaj khov kev ua haujlwm ntawm daim phiaj hluav taws xob, thiab txiav txim siab txog kev lag luam thiab kev sib raug zoo ntawm qhov chaw nres tsheb hydropower.Cov txiaj ntsig tau pom tias hydraulic stability tshwm sim los ntawm turbulent pulsation ntawm turbine yog ib qho tseem ceeb rau kev txiav txim siab lub lag luam stability ntawm turbine.Nyob rau hauv qhov tseeb, nyob rau hauv lub lag luam txheej txheem ntawm hydropower units, kev co yog feem ntau tshwm sim los ntawm mechanical thiab hluav taws xob vim li cas ntxiv rau lub vibration los ntawm hydraulic instability.Raws li kev txheeb cais, kwv yees li 80% ntawm kev ua tsis tiav lossis kev sib tsoo ntawm cov chav dej hydropower tau cuam tshuam hauv cov cim kev vibration.Yog li ntawd, nws yog ib qho tseem ceeb heev los kawm txog qhov kev kuaj xyuas qhov txhaum ntawm chav dej hydropower thiab ua qhov kev kuaj xyuas ntse ntawm kev co txhaum ntawm hydropower unit rau kev txhim kho qhov kev kuaj xyuas qhov txhaum ntawm hydropower unit hauv Suav teb thiab txo qhov sib txawv nrog cov cuab yeej zoo sib xws nyob txawv teb chaws.

Nrog rau kev nce ntawm lub peev xwm thiab cov qauv ntsuas ntawm chav tsev hydro-generator, kev ruaj ntseg ntawm chav ua haujlwm tau dhau los ua qhov teeb meem kev tshawb fawb thiab kev tsim vaj tsev sai sai.Kev tsom xam qhov tob ntawm kev vibration mechanism ntawm chav tsev hydro-generator tuaj yeem ua kom zoo dua rau nws txoj kev ntseeg siab ntawm kev ua haujlwm thiab kev zam lossis txo qhov kev puas tsuaj tshwm sim los ntawm kev co tsis ua haujlwm rau chav tsev.Nws yog ib qho tseem ceeb rau kev nkag siab txog kev vibration ntawm hydraulic turbine.

Cov laj thawj tseem ceeb ntawm mechanical vibration yog:

Kev sib raug zoo ntawm cov ncej loj ntawm lub flange, loosening ntawm kev sib txuas los yog loosening ntawm qhov kho qhov chaw ua rau kev co ntawm cov ncej loj tawg kab;

Kev vibration ntawm lub rotating ib feem ntawm chav tsev vim huab hwm coj imbalance, khoov los yog ntog ntawm qhov chaw;

Kev vibration tshwm sim los ntawm kev sib txhuam ntawm qhov rotating ib feem thiab qhov chaw ruaj khov ntawm chav tsev, qhov sib txawv loj ntawm cov kev taw qhia bearing hav txwv yeem, tsis sib xws thrust bearing bush, xoob lub taub hau thiab lwm yam.

Cov kev vibration tshwm sim los ntawm kev siv tshuab lossis kev ua txhaum muaj cov yam ntxwv zoo sib xws.Lub vibration zaus yog zaus hloov dua siab tshiab los yog ntau zaus hloov dua siab tshiab, thiab lub zog tsis sib npaug yog radial lossis kab rov tav.

Electromagnetic vibration tuaj yeem muab faib ua ob hom: rotational zaus vibration thiab polar zaus vibration.Lub tshuab hluav taws xob ua rau cov zaus hloov pauv kev vibration yog feem ntau luv luv ntawm rotor winding, tsis sib xws ntawm huab cua sib txawv ntawm lub rotor ruaj khov, kev ua haujlwm tsis zoo thiab kev txiav txim ntawm cov hlau nplaum tsis raug, ua rau cov hlau nplaum sib nqus asymmetry, sib nqus nro tsis txaus thiab kev co.Stator core loosening ua rau 100Hz huab zaus kev co.

Guangxi Dingbo Power Equipment Manufacturing Co., Ltd. tsim nyob rau hauv 2006, yog ib lub chaw tsim khoom 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 zog ntau 20kw-3000kw, thiab dhau los ua lawv lub Hoobkas OEM thiab cov chaw siv tshuab.
