Kukho iintlobo ezininzi zeejenereyitha ze-hydro.Namhlanje, makhe sazise nge-axial-flow hydro generator ngokweenkcukacha.Ukusetyenziswa kwe-axial-flow hydro generator kwiminyaka yakutshanje kuphuhliso lwentloko yamanzi kunye nobukhulu obukhulu.Uphuhliso lwee-axial-flow turbines zasekhaya nalo luyakhawuleza.Kukho iindidi ezimbini zeeinjini zokubheqa ezihamba ngeaxial ezifakwe kwisikhululo sombane esakhiweyo saseGezhouba, esinye sazo esinobubanzi bembaleki obuyi-11.3m, nto leyo engumda wembaleki wee turbines ezifanayo ehlabathini.Nazi izinto eziluncedo kunye nezingeloncedo kwi-intermediate axial flow turbine.
Izinto ezilungileyo ze-axial flow turbine
Xa kuthelekiswa ne-Francis turbine, i-axial-flow turbine inezi nzuzo ziphambili zilandelayo:
1. Isantya esiphezulu esithile kunye neempawu ezintle zamandla.Ke ngoko, isantya seyunithi kunye nokuhamba kweyunithi kuphezulu kunelo kaFrancis turbine.Ngaphantsi kwentloko efanayo kunye neemeko eziphumayo, inokunciphisa kakhulu ubungakanani beyunithi ye-hydraulic turbine generator unit, ukunciphisa ubunzima beyunithi kunye nokugcina ukusetyenziswa kwezinto eziphathekayo, ngoko kunenzuzo ephezulu yezoqoqosho.
2. Ubume bomphezulu kunye noburhabaxa bomphezulu weebhlewudi zembaleki ze-axial-flow turbine zilula ukuhlangabezana neemfuno zokwenziwa.Ngenxa yokuba iincakuba ze-axial flow propeller turbine zinokujikeleza, umndilili osebenzayo uphezulu kunolo we-Francis turbine.Xa umthwalo kunye nentloko zitshintsha, ukusebenza kakuhle kutshintsha kancinci.
3. Iiblawudi zembaleki ze-axial flow paddle turbine zinokuchithwa ukuze kube lula ukwenziwa nothutho.
Ke ngoko, i-axial-flow turbine ihlala izinzile kuluhlu olukhulu lokusebenza, inongcangcazelo oluncinci, kwaye inokusebenza okuphezulu kunye nesiphumo.Kuluhlu lwentloko yamanzi aphantsi, iphantse ithathe indawo ye-Francis turbine.Kumashumi eminyaka akutshanje, yenze uphuhliso olukhulu kunye nesicelo esibanzi malunga nomthamo weyunithi enye kunye nentloko yamanzi.
3, Ukungalungi kwe-axial flow turbine
Nangona kunjalo, i-axial-flow turbine nayo inezinto ezingeloncedo kwaye iyanciphisa umda wosetyenziso.Iintsilelo zayo eziphambili zezi:
1. Inani lee-blades lincinci kunye ne-cantilever, ngoko ke amandla ahluphekile kwaye awakwazi ukusetyenziswa kwizikhululo zamanzi aphakathi kunye nentloko ephezulu.
2. Ngenxa yokuhamba kweyunithi enkulu kunye nesantya esiphezulu seyunithi, inobude obuncinci bokufunxa kune-Francis turbine phantsi kwentloko yamanzi enye, okukhokelela kubunzulu obukhulu bokumbiwa kunye notyalo-mali oluphezulu lwesiseko sesikhululo samandla.
Ngokwale ntsilelo ingentla ye-axial-flow turbine, intloko yesicelo se-axial-flow turbine iphuculwa ngokuqhubekayo ngokwamkela izinto ezintsha ezinamandla kunye nokuchasana kwe-cavitation kwimveliso ye-turbine kunye nokuphucula imeko yoxinzelelo lwee-blades kuyilo.Okwangoku, uluhlu lwentloko yesicelo se-axial flow propeller turbine yi-3-90 m, engene kwindawo ye-Francis turbine.Umzekelo, imveliso ye-* * * yomatshini omnye we-axial flow propeller turbine yangaphandle yi-181700 kW, * * * intloko yi-88m, kunye nedayamitha yembaleki yi-10.3M.Isiphumo esisodwa se-axial flow propeller turbine eveliswe eTshayina yi-175000 kW, * * * intloko yi-78m, kwaye ububanzi be-* * * imbaleki yi-11.3m.I-Axial flow fixed propeller turbine ine-blades esisigxina kunye nesakhiwo esilula, kodwa ayikwazi ukuziqhelanisa nezikhululo zombane wamanzi kunye notshintsho olukhulu kwintloko yamanzi kunye nomthwalo.Kwizikhululo zombane omkhulu wamanzi ezinentloko yamanzi ezinzileyo kwaye zisebenza njengomthwalo osisiseko okanye iiyunithi ezininzi, zinokuqwalaselwa emva kokuthelekiswa koqoqosho xa amandla ombane exesha lonyaka emaninzi.Uluhlu lwentloko yamanzi esebenzayo luyi-3-50m.I-Axial flow propeller turbine ngokubanzi ithatha isixhobo esithe nkqo, kwaye inkqubo yayo yokusebenza iyafana naleyo ye-Francis turbine, Umahluko kukuba xa umthwalo utshintsha, ayilawuli nje ukujikeleza kwe-vane yesikhokelo, kodwa ikwalawula ukujikeleza kwe iblade yembaleki ukugcina ukusebenza kakuhle.
Sazisa kwakhona iFrancis turbine ngaphambili.Phakathi kweejenereyitha ze-hydro, i-injini ye-Francis yahluke kakhulu kwi-axial-flow turbine.Umzekelo, iifom zesakhiwo sembaleki yazo zahlukile.Iincakuba ze-Francis turbine ziphantse zangqamana neshaft engundoqo, ngelixa ezo ze-axial flow turbine ziphantse zangqamana neshaft engundoqo.
