Cov yam ntxwv ntawm Francis Turbine
Lub tshuab nqus cua Francis muaj kev cog lus thiab txuag, thiab tuaj yeem hloov mus rau ntau cov dej taub hau. Nws yog ib qho ntawm feem ntau siv txoj kev turbine hom nyob hauv lub ntiaj teb. Thaum cov dej ntws los ntawm qhov zoo li qhov kev sib tw ntawm lub log, nws nkag mus rau hauv qhov kev taw qhia radial thiab ntws tawm axially, yog li nws tseem hu ua kev ntsuas radial axial flow turbine.
Nws yog qhov tsim rau cov taub hau dej txog li 20 meters txog 700 meters. Nws yog yooj yim hauv cov qauv, ruaj khov hauv kev ua haujlwm thiab siab hauv kev ua tau zoo, tab sis feem ntau nws siv nyob hauv nruab nrab lub taub hau (50 meters txog 400 meters). Ib lub tshuab tawm ntawm kaum tawm kilowatts mus txog ntau pua txhiab kilowatts. Tam sim no, qhov ntau tshaj plaws ntawm cov kev txhim kho lub zog no ntau dua 700,000 kilowatts. Nws yog ib qho ntawm feem ntau siv cov turbines. Tuam Tshoj 700 MW chav nrog ib-chav muaj peev xwm tau muab tso rau hauv kev ua haujlwm ntawm Peb Gorges, thiab 800 MW chav tsev sib xyaw tau siv nyob hauv Xiangjiaba.
