Kev Paub Txog Hydropower

Pumped cia hydropower chaw nres tsheb yog qhov siv dav tshaj plaws thiab cov cuab yeej paub tab hauv cov khoom siv hluav taws xob loj, thiab lub peev xwm ntawm qhov chaw nres tsheb fais fab tuaj yeem ncav cuag gigawatt. Tam sim no, lub twj tso kua mis cia chaw nres tsheb nrog kev loj hlob loj tshaj plaws hauv ntiaj teb. Pumped khaws cia ...Nyeem ntxiv»

Muaj ntau ntau hom hydro generators. Niaj hnub no, cia peb qhia txog axial-flow hydrogenerator kom ntxaws. Daim ntawv thov ntawm axial-flow hydro generator nyob rau hauv xyoo tas los no tsuas yog kev loj hlob ntawm lub taub hau dej siab thiab loj loj. Txoj kev loj hlob ntawm domestic axial-flow turbines kuj ceev....Nyeem ntxiv»

Qhov ceev ntawm cov dej turbines yog qhov tsawg, tshwj xeeb tshaj yog cov dej ntsug turbine. Txhawm rau tsim kom muaj 50Hz AC, lub tshuab hluav taws xob dej turbine tau txais ntau khub sib nqus ncej qauv. Rau cov dej turbine generator nrog 120 revolutions ib feeb, 25 khub ntawm cov hlau nplaum yuav tsum. Beca...Nyeem ntxiv»

Nws tau 111 xyoo txij li thaum Tuam Tshoj pib tsim shilongba hydropower chaw nres tsheb, thawj qhov chaw nres tsheb hydropower nyob rau hauv 1910. Nyob rau hauv no ntau tshaj 100 xyoo, los ntawm cov ntsia muaj peev xwm ntawm shilongba hydropower chaw nres tsheb ntawm tsuas yog 480 kW mus rau 370 lab KW tam sim no qeb duas nyob rau hauv lub ntiaj teb no, Tuam Tshoj ...Nyeem ntxiv»

Dej turbine yog ib yam ntawm cov tshuab turbine hauv cov tshuab ua kua. Thaum ntxov li 100 BC, tus qauv ntawm cov dej turbine - dej turbine tau yug los. Thaum lub sijhawm ntawd, lub luag haujlwm tseem ceeb yog tsav cov tshuab rau kev ua qoob loo thiab ua dej. Dej turbine, raws li ib tug mechanical ntaus ntawv powered ...Nyeem ntxiv»

Pelton turbine (tseem txhais: Pelton waterwheel lossis Bourdain turbine, Lus Askiv: Pelton log lossis Pelton Turbine) yog ib hom kev cuam tshuam turbine, uas yog tsim los ntawm American inventor Lester W. Tsim los ntawm Alan Pelton. Pelton turbines siv dej ntws thiab ntaus lub log dej kom tau lub zog, ...Nyeem ntxiv»

Kev sib hloov ceev ntawm hydraulic turbines yog qhov tsawg, tshwj xeeb tshaj yog rau ntsug hydraulic turbines. Txhawm rau tsim 50Hz alternating tam sim no, hydraulic turbine generator txais cov qauv ntawm ntau khub ntawm cov hlau nplaum. Rau hydraulic turbine generator nrog 120 revolutions p ...Nyeem ntxiv»

Cov dej turbine yog ib qho turbomachinery hauv cov tshuab ua kua. Thaum ntxov li ntawm 100 BC, tus qauv ntawm cov dej turbine, lub log dej, tau yug los. Thaum lub sijhawm ntawd, lub luag haujlwm tseem ceeb yog tsav cov tshuab rau kev ua qoob loo thiab ua dej. Lub log dej, raws li cov cuab yeej siv tshuab uas siv wat...Nyeem ntxiv»

Hydro generator yog tsim los ntawm rotor, stator, ncej, thrust bearing, coj bearing, txias, nres thiab lwm yam tseem ceeb Cheebtsam (saib daim duab). Lub stator feem ntau yog tsim los ntawm thav duab, hlau core, winding thiab lwm yam khoom. Lub stator core yog ua los ntawm txias dov silicon steel los xij, uas tuaj yeem ua ...Nyeem ntxiv»

1. Kev ntsuam xyuas cov load shedding thiab load shedding ntawm hydro generator units yuav tsum ua alternately. Tom qab chav tsev tau pib thauj khoom, kev ua haujlwm ntawm chav tsev thiab cov khoom siv hluav taws xob cuam tshuam yuav tsum raug kuaj xyuas. Yog tias tsis muaj qhov txawv txav, qhov kev xeem tsis lees paub tuaj yeem nqa tawm acc ...Nyeem ntxiv»

1. Ua rau cavitation nyob rau hauv turbines Yog vim li cas rau lub cavitation ntawm lub turbine complex. Lub siab faib nyob rau hauv lub turbine khiav yog tsis sib xws. Piv txwv li, yog tias tus neeg khiav dej num tau teeb tsa siab dhau los ntawm cov dej ntws qis, thaum cov dej kub ceev ntws los ntawm cov xovxwm qis ...Nyeem ntxiv»

Pumped cia yog qhov siv dav tshaj plaws thiab paub tab technology nyob rau hauv loj-scale zog cia, thiab lub peev xwm ntawm cov chaw nres tsheb fais fab tuaj yeem ncav cuag gigawatts. Tam sim no, qhov loj tshaj plaws thiab loj tshaj plaws ntsia lub zog cia nyob rau hauv lub ntiaj teb no yog pumped hydro. Pumped cia technology yog mature thiab sta ...Nyeem ntxiv»
