Tanena kale kuti turbine ya hydraulic imagawidwa kukhala turbine yamphamvu ndi turbine yamphamvu. Magulu ndi kutalika kwamutu koyenera kwa ma turbines okhudzidwa adayambitsidwanso kale. Ma turbine amphamvu amatha kugawidwa mu: ma turbines a ndowa, ma oblique impact turbines ndi ma turbine odina kawiri, omwe azidziwitsidwa pansipa.
Wothamanga wa turbine ya impingement nthawi zonse amakhala m'mlengalenga, ndipo madzi othamanga kwambiri amachokera ku penstock asinthidwa kukhala ndege yaulere yothamanga kwambiri asanalowe mu turbine. kusintha, kotero kuti mphamvu zake zambiri za kinetic zimasamutsidwa ku vanes, zomwe zimayendetsa wothamanga kuti azizungulira. Pa nthawi yonse ya jeti ikukankhira pa chopondera, kukakamiza kwa jet kumakhalabe kosasinthika, komwe kumakhala kupanikizika kwa mumlengalenga.
Chidebe cha turbine: chomwe chimadziwikanso kuti chometa ubweya wa thonje, monga momwe tawonetsera pachithunzichi. Jeti yaulere yothamanga kwambiri kuchokera pamphuno imagunda ma vanes molunjika motsatira njira ya tangential ya circumference yothamanga. Mtundu uwu wa turbine ndi woyenera kwa malo opangira magetsi opangira magetsi okhala ndi mutu wapamwamba komanso otaya pang'ono, makamaka pamene mutu ukuposa 400m, chifukwa cha kuchepa kwa mphamvu zamapangidwe ndi cavitation, turbine ya Francis si yoyenera, ndipo turbine yamtundu wa ndowa imagwiritsidwa ntchito nthawi zambiri. Mutu wamadzi wogwiritsidwa ntchito wa turbine ya chidebe chachikulu ndi pafupifupi 300-1700m, ndipo mutu wamadzi wogwiritsidwa ntchito wa turbine yaing'ono ya chidebe ndi pafupifupi 40-250m. Pakalipano, mutu wapamwamba wa turbine ya ndowa wagwiritsidwa ntchito pa 1767m (Austria Lesek Power Station), ndipo mutu wa mapangidwe a turbine ya chidebe cha Tianhu Hydropower Station m'dziko langa ndi 1022.4m.
Mtundu wa turbine wokhazikika
Jeti yaulere yochokera kumphuno imalowa muzitsulo kuchokera kumbali imodzi ya wothamanga ndikutuluka kuchokera kumbali ina kupita kumtunda wopita ku ndege yozungulira wothamanga. Poyerekeza ndi mtundu wa ndowa, kusefukira kwake kumakhala kokulirapo, koma mphamvu yake ndi yotsika, kotero mtundu uwu wa turbine umagwiritsidwa ntchito m'malo ang'onoang'ono ndi apakatikati amagetsi amagetsi, ndipo mutu womwe umagwira nthawi zambiri ndi 20-300m.
dinani kawiri turbine
Jeti yochokera kumphuno imasokoneza masamba othamanga kawiri motsatizana. Mtundu woterewu wa turbine ndi wosavuta kupanga komanso wosavuta kupanga, koma umakhala ndi mphamvu zochepa komanso mphamvu zothamanga. Ndiwoyenera kumagawo ang'onoang'ono opangira magetsi opangira mphamvu yamadzi omwe amatulutsa mphamvu imodzi yokha yosapitilira 1000kW, ndipo mutu wake wamadzi womwe umagwiritsidwa ntchito nthawi zambiri ndi 5-100m.
Awa ndi magulu a ma turbines okhudzidwa. Poyerekeza ndi ma turbines okhudzidwa, pali magawo ochepa a ma turbine amphamvu. Komabe, m'madera omwe ali ndi kusiyana kwakukulu kwa madzi, makina opangira magetsi amagwira ntchito bwino, monga mtsinje wa Yarlung Zangbo m'dziko langa, kumene dontho limafika mamita oposa 2,000, ndipo sizingatheke kumanga madamu nthawi imodzi. Chifukwa chake, turbine yamphamvu yakhala chisankho chabwino kwambiri.
