Ho na le mefuta e mengata ea lijenereithara tsa motlakase oa metsi.Kajeno, ke tla hlahisa lijenereithara tsa axial flow hydroelectric ka botlalo.Tšebeliso ea lijenereithara tsa li-axial flow turbine lilemong tsa morao tjena ke haholo-holo nts'etsopele ea hlooho e phahameng le boholo bo boholo.Li-turbine tsa lapeng tsa axial-flow li ntse li tsoela pele ka potlako.Ho hahiloe li-turbine tse peli tsa mofuta oa axial-flow-paddle-type tse kentsoeng Seteisheneng sa Motlakase oa Motlakase oa Gezhouba.E 'ngoe ea tsona e bophara ba limithara tse 11,3, eo hajoale e leng eona e kholo ka ho fetisisa lefatšeng..Mona ke melemo le melemo ea li-axial flow turbines.
Melemo ea axial flow turbine
Ha ho bapisoa le li-turbine tsa Francis, li-axial flow turbine li 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 turbine ea Francis.Tlas'a maemo a tšoanang a hlooho le tlhahiso ea metsi, e ka fokotsa haholo boholo ba yuniti ea jenereithara ea turbine, ea fokotsa boima ba yuniti, 'me ea boloka tšebeliso ea thepa, kahoo e na le moruo.hodimo.
2. Sebōpeho sa holim'a metsi le holim'a metsi a marang-rang a lehare la semathi sa axial flow turbine se ka finyella litlhoko tsa tlhahiso habonolo.Hobane mahare a turbine ea axial-flow rotary-paddle turbine a khona ho potoloha, karolelano ea katleho e phahame ho feta ea turbine ea phallo e tsoakiloeng.Ha hlooho ea mojaro le metsi e fetoha, katleho ha e fetohe haholo.
3. Li-blades tsa semathi tsa turbine ea axial-flow paddle turbine li ka qhaqhoa, tse loketseng bakeng sa tlhahiso le lipalangoang.
Ka hona, turbine ea axial flow e ka boloka botsitso sebakeng se seholo sa ts'ebetso, ka ho sisinyeha ho fokolang, le katleho e phahameng le tlhahiso.Sebakeng se tlaase-hlooho, e se e batla e nkile sebaka sa turbine ea Francis.Lilemong tse mashome tsa morao tjena, ka bobeli ba matla a yuniti e le 'ngoe le tšebeliso ea hlooho ea metsi, ho bile le tsoelo-pele e kholo,' me ts'ebeliso ea eona e boetse e pharaletse haholo.
Mathata a axial flow turbine
Leha ho le joalo, turbine ea axial flow e boetse e na le mefokolo mme e fokotsa boholo ba eona ba ts'ebeliso.Mefokolo e kholo ke:
1. Palo ea li-blades e nyenyane, 'me ke cantilever, kahoo matla a fokola,' me a ke ke a sebelisoa liteisheneng tsa matla a metsi a mahareng le a phahameng.
2. Ka lebaka la tekanyo e kholo ea phallo ea yuniti le lebelo le phahameng la yuniti, e na le bophahamo bo fokolang ba ho hula ho feta turbine ea Francis tlas'a boemo bo tšoanang ba hlooho, e leng se etsang hore ho be le botebo bo boholo ba ho cheka bakeng sa motheo oa seteishene sa matla le letsete le batlang le le holimo.
Ho ea ka mefokolo e boletsoeng ka holimo ea li-axial flow turbines, lisebelisoa tse ncha tse matla tse khahlanong le cavitation li sebelisoa ha ho etsoa li-turbine 'me matla a li-blades a ntlafatsoa ka moralo, e le hore hlooho ea kopo ea li-axial flow turbines e tsoele pele ho ntlafatsoa.Hajoale, hlooho ea ts'ebeliso ea turbine ea axial-flow paddle ke 3 ho 90 m, mme e kene sebakeng sa turbine ea Francis.Mohlala, palo e phahameng ka ho fetesisa ea yuniti e le 'ngoe ea li-turbine tsa kantle tsa axial-flow paddle ke 181,700 kW, hlooho e phahameng ea metsi ke 88m, mme bophara ba semathi ke 10.3m.Phaello e phahameng ka ho fetesisa ea mochini o le mong oa turbine ea axial-flow paddle e hlahisoang naheng ea heso ke 175,000 kW, hlooho e phahameng ea metsi ke 78m, mme bophara bo boholo ba semathi ke 11.3m.Axial-flow fixed-propeller turbine e na le li-blades tse 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.E na le hlooho e tsitsitseng ea metsi 'me e sebetsa e le setsi sa motlakase kapa setsi sa motlakase se nang le mefuta e mengata.Ha matla a linako tsa selemo a le mangata, papiso ea moruo le eona e ka khoneha.E ka nahanoa.Sebaka sa eona sa hlooho se sebetsang ke 3-50m.Li-turbine tsa Axial-flow paddle hangata li sebelisa lisebelisoa tse emeng.Ts'ebetso ea eona ea ts'ebetso e ts'oana le ea li-turbine tsa Francis.Phapang ke hore ha mojaro o fetoha, ha o laole feela ho potoloha ha li-vanes tsa tataiso., Ha o ntse o lokisa ho potoloha ha li-blades tsa semathi ho boloka ts'ebetso e phahameng.
Pele, re boetse re tsebisitse li-turbine tsa Francis.Har'a lijenereithara tsa turbine, ho ntse ho na le phapang e kholo lipakeng tsa li-turbine tsa Francis le li-axial flow turbines.Ka mohlala, sebōpeho sa limathi tsa bona se fapane.Li-blades tsa Francis turbines li batla li bapile le moqomo o ka sehloohong, ha li-axial flow turbines li batla li le ka lehlakoreng le leng ho ea ho moqomo o ka sehloohong.
