Jenereithara ea Motlakase oa Metsi ea 500KW Francis Hydro Turbine Generator ho la Uzbekistan
Tlhaloso ea turbine ea Francis ke motsoako oa turbine ea impulse le reaction, moo mahare a potolohang a sebelisa matla a reaction le impulse a metsi a phallang ka har'a 'ona a hlahisang motlakase ka katleho e kholoanyane. Turbine ea Francis e sebelisoa bakeng sa tlhahiso ea motlakase khafetsa liteisheneng tsa motlakase oa metsi tse mahareng kapa tse kholo.
Liturbine tsena li ka sebelisoa bakeng sa lihlooho tse tlase ho fihla ho limithara tse 2 le bophahamo ba limithara tse 300. Ho feta moo, liturbine tsena li na le molemo kaha li sebetsa hantle ka ho lekana ha li behiloe ka ho otloloha joalo ka ha li etsa ha li lebisitsoe holimo. Metsi a fetang ka har'a turbine ea Francis a lahleheloa ke khatello, empa a lula ka lebelo le tšoanang, kahoo a ka nkoa e le turbine ea karabelo.
Tlhaloso ea setšoantšo sa karolo e kholo ea turbine e 'ngoe le e 'ngoe ea Francis ke e latelang.
Sekoahelo sa Spiral
Sekoti se potolohang ke sebaka sa ho kenya metsi ho ya ho turbine. Metsi a phallang ho tloha letamong kapa letamong a etswa hore a fete ka hara phaephe ena ka kgatello e phahameng. Mahare a diturbine a bewa ka sedikadikwe, ho bolelang hore metsi a otlang mahare a turbine a lokela ho phalla ka hara mothapo o chitja bakeng sa ho otla ka katleho. Kahoo sekoti se potolohang se a sebediswa, empa ka lebaka la motsamao o chitja wa metsi, a lahlehelwa ke kgatello ya ona.
Ho boloka khatello e tšoanang, bophara ba sekoahelo bo fokotseha butle-butle, ka hona, lebelo kapa motsamao o ts'oanang o otla mahare a runner.
Lula Li-Vanes
Li-vane tsa ho ema le ho tataisa li tataisa metsi ho ea ho mahare a runner. Li-vane tsa ho ema li lula li eme sebakeng sa tsona 'me li fokotsa ho potoloha ha metsi ka lebaka la phallo ea mahlaseli, ha e kena ho mahare a runner, ka hona, e etsa hore turbine e sebetse hantle haholoanyane.
Li-Vane tsa Tataiso
Li-vane tsa tataiso ha li eme, li fetola sekhutlo sa tsona ho latela tlhoko ea ho laola sekhutlo sa ho otla ha metsi ho ea ho makhasi a turbine ho eketsa bokhoni. Li boetse li laola sekhahla sa phallo ea metsi ka har'a makhasi a runner kahoo li laola tlhahiso ea matla ea turbine ho latela mojaro o holim'a turbine.
Mahare a Runner
Mahare a runner ke pelo ea turbine efe kapa efe ea Francis. Tsena ke litsi moo mokelikeli o otlang teng 'me matla a tangential a tšusumetso a etsa hore shaft ea turbine e potolohe, e hlahise torque. Ho hlokahala tlhokomelo e haufi-ufi moralong oa likhutlo tsa lehare moo ho kenang le ho tsoa teng, kaha tsena ke liparamente tse kholo tse amang tlhahiso ea matla.
Mahare a matha a na le likarolo tse peli. Karolo e ka tlase e entsoe ka sebopeho sa bakete e nyane ho potoloha turbine ka ho sebelisa ketso ea metsi ea ho sisinyeha. Ha karolo e ka holimo ea mahare e sebelisa matla a karabelo a metsi a phallang ka har'a eona. Mahare a matha a potoloha ka har'a matla ana a mabeli.
Moqomo oa ho Sebetsa
Kgatelelo e tswang ho turbine ya karabelo hangata e ka tlase ho kgatelelo ya sepakapaka. Metsi a tswang, a ke ke a ntshwa ka ho toba ho ya tailrace. Phaephe kapa phaephe ya sebaka se ntseng se eketseha butle-butle e sebediswa bakeng sa ho ntsha metsi ho tloha ho turbine e tswang ho ya tailrace.
Phaephe ena ea sebaka se ntseng se eketseha e bitsoa Draft Tube. Qetello e 'ngoe ea phaephe e hokahane le phallo ea semathi. Leha ho le joalo, pheletso e 'ngoe e qoelitsoe ka tlase ho boemo ba metsi peisong ea mohatla.
Molao-motheo oa Francis Turbine o Sebetsang ka Setšoantšo
Li-turbine tsa Francis li sebelisoa khafetsa lifemeng tsa motlakase oa metsi. Li-femeng tsena tsa motlakase, metsi a nang le khatello e phahameng a kena ka har'a turbine ka sekoting sa khetla ea khofu (volute). Motsamao ona o fokotsa khatello ea metsi ha a ntse a kobeha ka har'a tube; leha ho le joalo, lebelo la metsi le lula le sa fetohe. Kamora ho feta ka har'a volute, metsi a phalla ka har'a li-vane tse tataisang 'me a lebisitsoe ho mahare a semathi ka likhutlo tse ntle. Kaha metsi a tšela mahare a kobehileng hantle a semathi, metsi a khelosoa hanyane ka lehlakoreng. Sena se etsa hore metsi a lahleheloe ke karolo e itseng ea motsamao oa 'ona oa "ho potoloha". Metsi a boetse a khelosoa ka lehlakoreng le otlolohileng ho tsoa ka har'a tube ea ho hula ho ea peisong ea mohatla.
Phaephe e boletsoeng e fokotsa lebelo la tlhahiso ea metsi ho fumana matla a mangata ho tsoa metsing a kenang. Ts'ebetso ea metsi a khelosoang ka har'a mahare a mathang e fella ka matla a sutumetsang mahare ho ea lehlakoreng le leng ha metsi a ntse a khelosoa. Matla ao a karabelo (joalokaha re tseba ho tsoa molaong oa boraro oa Newton) ke ona a etsang hore matla a nkuoe ho tloha metsing ho ea ho shaft ea turbine, ho potoloha ho tsoelang pele. Kaha turbine e tsamaea ka lebaka la matla ao a karabelo, li-turbine tsa Francis li khetholloa e le li-turbine tsa karabelo. Ts'ebetso ea ho fetola tataiso ea phallo ea metsi e boetse e fokotsa khatello ka har'a turbine ka boeona.
