Ho na le mefuta e mengata ea lijenereithara tsa hydro. Kajeno, a re ke re tsebiseng jenereithara ea axial-flow hydro ka botlalo. Tšebeliso ea jenereithara ea axial-flow hydro generator lilemong tsa morao tjena ke haholo-holo nts'etsopele ea hlooho ea metsi a phahameng le boholo bo boholo. Nts'etsopele ea li-axial-flow turbines tsa malapeng le tsona li potlakile. Ho na le mefuta e 'meli ea li-axial-flow paddle turbines tse kentsoeng seteisheneng sa motlakase sa metsi sa Gezhouba se hahiloeng, se seng sa tsona se nang le bophara ba 11.3m, e leng bophara ba li-turbine tse tšoanang lefatšeng. Mona ke melemo le mathata a mahareng a axial flow turbine.
Melemo ea axial flow turbine
Ha ho bapisoa le Francis turbine, axial-flow turbine e na le melemo e latelang:
1. Lebelo le khethehileng le phahameng le litšobotsi tse ntle tsa matla. Ka hona, lebelo la yuniti ea eona le phallo ea yuniti li phahame ho feta tsa Francis turbine. Tlas'a maemo a tšoanang a hlooho le lihlahisoa, e ka fokotsa haholo boholo ba hydraulic turbine jenereithara ea jenereithara, ea fokotsa boima ba yuniti le ho boloka tšebeliso ea thepa, kahoo e na le melemo e phahameng ea moruo.
2. Sebopeho sa bokaholimo le bokhabane ba holim'a li-blades tsa semathi sa axial-flow turbine li bonolo ho fihlela litlhoko tsa tlhahiso. Hobane mahare a turbine a axial flow propeller turbine a ka potoloha, karolelano ea katleho e phahame ho feta ea Francis turbine. Ha mojaro le hlooho li fetoha, katleho e fetoha hanyane.
3. Li-blades tsa semathi tsa axial flow paddle turbine li ka aroloa ho thusa ho etsa le ho tsamaisa.
Ka hona, turbine ea axial-flow e lula e tsitsitse sebakeng se seholo sa ts'ebetso, ha e na ho sisinyeha ho fokolang, 'me e na le ts'ebetso e phahameng le tlhahiso. Ka har'a metsi a tlase a hlooho, e batla e nkela sebaka sa turbine sa Francis. Lilemong tse mashome tsa morao tjena, e entse nts'etsopele e kholo le ts'ebeliso e pharaletseng mabapi le bokhoni ba yuniti e le 'ngoe le hlooho ea metsi.
3, Mefokolo ea axial flow turbine
Leha ho le joalo, turbine ea axial-flow le eona e na le mefokolo 'me e fokotsa boholo ba eona ba ts'ebeliso. Mefokolo ea eona e kholo ke:
1. Palo ea li-blades e nyenyane le cantilever, kahoo matla a fokola 'me a ke ke a sebelisoa ho liteishene tsa matla a metsi a mahareng le a phahameng.
2. Ka lebaka la phallo e kholo ea yuniti le lebelo le phahameng la yuniti, e na le bophahamo bo bonyenyane ba ho hula ho feta Francis turbine tlas'a hlooho e tšoanang ea metsi, e bakang botebo bo boholo ba ho cheka le matsete a batlang a phahame a motheo oa seteishene sa matla.
Ho ea ka mefokolo e ka holimo ea axial-flow turbine, hlooho ea kopo ea axial-flow turbine e tsoela pele ho ntlafatsoa ka ho amohela lisebelisoa tse ncha tse nang le matla a phahameng le khanyetso ea cavitation ha ho etsoa li-turbine le ho ntlafatsa boemo ba khatello ea li-blades ka moralo. Hona joale, lisebelisoa tsa hlooho ea kopo ea axial flow propeller turbine ke 3-90 m, e keneng sebakeng sa Francis turbine. Mohlala, tlhahiso ea * * * mochini o le mong oa turbine ea kantle ea axial flow propeller ke 181700 kW, * * * hlooho ke 88m, 'me bophara ba semathi ke 10.3M. Phallo e le 'ngoe ea turbine ea axial flow propeller e hlahisoang Chaena ke 175000 kW, * * * hlooho ke 78m, 'me bophara ba * * * semathi ke 11.3m. Axial flow fixed propeller turbine e na le mahare a tsitsitseng le sebopeho se bonolo, empa ha e khone ho ikamahanya le liteishene tsa motlakase oa metsi ka liphetoho tse kholo hloohong ea metsi le mojaro. Bakeng sa liteishene tse kholo tse fehlang matla a metsi tse nang le hlooho e tsitsitseng ea metsi 'me li sebetsa e le thepa ea motheo kapa li-unit tse ngata, e ka boela ea nkoa ka mor'a papiso ea moruo ha matla a motlakase a linako tsa selemo a le mangata. Sebaka sa eona sa metsi se sebetsang ke 3-50m. Axial flow propeller turbine ka kakaretso e amohela sesebelisoa se emeng, mme ts'ebetso ea eona ea ts'ebetso e ts'oana le ea Francis turbine, Phapang ke hore ha mojaro o fetoha, ha o laole feela ho potoloha ha vane ea tataiso, empa hape o laola ho potoloha ha lehare la semathi ho boloka ts'ebetso e phahameng.
Re boetse re tsebisitse turbine ea Francis pele. Har'a lijenereithara tsa hydro, turbine ea Francis e fapane haholo le ea axial-flow turbine. Ka mohlala, mefuta ea meralo ea semathi sa bona e fapane. Maqhubu a turbine ea Francis a batla a bapile le moqomo o ka sehloohong, athe axial flow turbine a batla a le ka lehlakoreng le ka sehloohong.
