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-turbine tsa axial-flow tsa malapeng le tsona li potlakile.Ho na le mefuta e 'meli ea li-axial-flow paddle turbines tse kentsoeng setsing 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 ea mantlha:
1. Lebelo le khethehileng le phahameng le litšobotsi tse ntle tsa matla.Ka hona, lebelo la yuniti le phallo ea yuniti li phahame ho feta tsa Francis turbine.Tlas'a maemo a tšoanang a hlooho le tlhahiso, 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. Sebōpeho sa bokaholimo le bokhabane ba holim'a marang-rang a li-axial-flow turbine li bonolo ho finyella litlhoko tsa tlhahiso.Hobane mahare a turbine a axial flow propeller turbine a khona ho potoloha, katleho e tloaelehileng 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 katleho e phahameng le tlhahiso.Har'a mefuta e mengata ea hlooho ea metsi a tlaase, e batla e nkela sebaka sa turbine ea 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 monya 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 turbine 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 nahanoa ka mor'a papiso ea moruo ha matla a motlakase a selemo a le mangata.Sebaka sa eona sa metsi se sebetsang ke 3-50m.Axial flow propeller turbine ka kakaretso e nka sesebelisoa se emeng, mme ts'ebetso ea eona ea ts'ebetso e ts'oana hantle le ea Francis turbine, Phapang ke hore ha mojaro o fetoha, ha o laole feela ho potoloha ha vane ea tataiso, empa hape e laola ho potoloha ha mochini o tataisang. semathi lehare ho boloka bokgoni bo 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.
