Li-turbine tsa Francis ke karolo ea bohlokoa ea limela tse fehlang motlakase ka metsi, li bapala karolo ea bohlokoa tlhahisong ea matla a hloekileng le a ka nchafatsoang. Li-turbine tsena li reheletsoe ka moqapi oa tsona, James B. Francis, 'me li sebelisoa haholo lits'ebetsong tse fapaneng tsa ho fehla motlakase lefatšeng ka bophara. Sehloohong sena, re tla hlahloba lintlha tsa bohlokoa le bohlokoa ba limela tsa matla a turbine tsa Francis sebakeng sa tlhahiso ea matla e tsitsitseng.
Anatomy ea Francis Turbines
Francis turbines ke mofuta oa turbine ea metsi e etselitsoeng ho sebetsa hantle tlas'a maemo a phahameng a hydraulic hlooho, hangata ho tloha ho 20 ho isa ho 700 metres. Moralo oa bona o kenyelletsa likarolo tsa phallo ea radial le axial, e leng se etsang hore li feto-fetohe bakeng sa mefuta e mengata ea phallo ea metsi.
Sebopeho sa motheo sa turbine ea Francis se na le lintlha tse 'maloa tsa bohlokoa:
Semathi: Ena ke pelo ea turbine, moo metsi a kenang le ho kopana le mahare ho hlahisa matla a mochine. Semathi se na le letoto la li-blades tse kobehileng tse etselitsoeng ho sebelisa matla a kinetic a phallo ea metsi.
Spiral Casing: The spiral casing e lebisa metsi ho semathi se nang le tahlehelo e fokolang ea matla. E thusa ho boloka phallo e tsitsitseng le khatello ha metsi a kena ka har'a turbine.
Draft Tube: Kamora ho feta semathing, metsi a tsoa ka har'a pompo ea metsi, e thusang ho fokotsa lebelo la ho tsoa le khatello, ho eketsa ho ntšoa ha matla.
Ts'ebetso ea Francis Turbines
Ts'ebetso ea li-turbine tsa Francis e ipapisitse le molao-motheo oa ho fetola matla a ka bang teng a metsi a oelang hore e be matla a mochini, ebe a fetoloa matla a motlakase. Mona ke kakaretso e nolofalitsoeng ea kamoo li sebetsang kateng:
Metsi a Kena: Metsi a khatello e phahameng a lebisitsoe ka har'a casing ea spiral, moo e kenang semathi.
Phetoho ea Matla: Ha metsi a phalla ka har'a semathi, a otla mahare a kobehileng, a etsa hore semathi se pote. Motsamao ona oa ho potoloha o fetola matla a kinetic a metsi hore e be matla a mochini.
Motlakase ho ea ho Matla a Motlakase: Semathi se potolohang se hokahane le jenereithara, e fetolang matla a mochini hore e be matla a motlakase ka melao-motheo ea induction ea motlakase.
Pheliso ea Motlakase: Matla a motlakase a fehloang ebe a kenngoa ka har'a marang-rang a motlakase bakeng sa ho abeloa malapeng le liindasteri.
Melemo ea Francis Turbine Power Plants
Litsi tsa motlakase tsa turbine tsa Francis li fana ka melemo e mengata:
Sebetsa: Li na le ts'ebetso e phahameng ho pholletsa le maemo a fapaneng a ts'ebetso, e leng se etsang hore li tšoanelehe bakeng sa merero e fapaneng ea motlakase oa metsi.
Ho feto-fetoha ha maemo: Li-turbine tsa Francis li ka ikamahanya le maemo a fetohang a phallo ea metsi 'me li khona ho sebetsana le lits'ebetso tse tlase le tse phahameng.
Matla a Hloekileng: Motlakase oa metsi o ka nchafatsoa 'me o hlahisa likhase tse fokolang tsa mocheso, e leng se tlatsetsang bokamosong bo tsitsitseng ba matla.
Ho tšepahala: Li-turbine tsena li tsebahala ka ho tšoarella ha tsona le bophelo bo bolelele ba tšebeletso, hangata ho feta lilemo tse mashome a 'maloa.
Qetello
Litsi tsa motlakase tsa turbine tsa Francis li eme e le bopaki ba boqapi ba batho ho sebelisa matla a metsi a phallang ho hlahisa motlakase o hloekileng. Li bapala karolo ea bohlokoa phetohong e lebisang mehloling ea matla a moshoelella, ho fana ka tharollo e tšepahalang le e bonolo ea tikoloho bakeng sa ho fihlela litlhoko tsa lefats'e tse ntseng li hola tsa eneji. Ha re ntse re tsoela pele ho hlahloba mekhoa e hloekileng le e sebetsang hantle ea ho hlahisa motlakase, li-turbine tsa Francis e ntse e le lejoe la motheo la ho fehla motlakase ka metsi.
