1, Kev faib ntawm lub peev xwm thiab qib ntawm hydro generator
Tam sim no, tsis muaj tus qauv sib koom ua ke rau kev faib tawm ntawm lub peev xwm thiab qhov ceev ntawm lub tshuab hluav taws xob hauv ntiaj teb. Raws li qhov xwm txheej hauv Suav teb, nws lub peev xwm thiab qhov ceev tuaj yeem faib ua pawg raws li cov lus hauv qab no:
Kev faib tawm ntsuas zog PN (kw) ntsuas ceev NN (R / min);
Qis qis, nruab nrab thiab siab ceev;
Lub tshuab hluav taws xob me me < 100 750-1500;
Lub tshuab hluav taws xob me me 100-500 < 375-600 750-1500;
Lub tshuab hluav taws xob loj nruab nrab 500-10000 < 375-600 750-1500; Lub tshuab hluav taws xob loj > 10000 < 100-375 > 375;
2, Hom kev teeb tsa ntawm lub tshuab hluav taws xob hydro
Cov qauv teeb tsa ntawm lub tshuab hluav taws xob hydro feem ntau yog txiav txim siab los ntawm hom hydraulic turbine. Muaj cov hom hauv qab no:
1) Cov qauv kab rov tav
Cov tshuab hluav taws xob hydro uas muaj cov qauv kab rov tav feem ntau yog tsav los ntawm cov turbines impulse. Cov chav dej turbine kab rov tav feem ntau siv ob lossis peb lub bearings. Cov qauv ntawm ob lub bearings muaj qhov zoo ntawm qhov ntev axial luv, cov qauv compact thiab yooj yim rau kev teeb tsa thiab kho. Txawm li cas los xij, thaum qhov ceev tseem ceeb ntawm lub shafting tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua lossis lub nra hnyav loj, cov qauv peb lub bearings yuav tsum tau txais yuav. Feem ntau cov chav hydraulic turbine generator hauv tsev yog cov chav me thiab nruab nrab. Cov chav loj kab rov tav nrog lub peev xwm ntawm 12.5mw kuj tsim tawm. Cov chav dej turbine generator kab rov tav tsim tawm txawv teb chaws tsis tshua muaj nrog lub peev xwm ntawm 60-70mw, thaum cov chav dej turbine generator kab rov tav nrog cov chaw nres tsheb cia khoom tuaj yeem muaj ib chav muaj peev xwm ntawm 300MW.
2) Cov qauv ntsug
Cov qauv ntsug yog siv dav hauv cov tshuab hluav taws xob turbine dej hauv tsev. Cov tshuab hluav taws xob turbine dej ntsug feem ntau yog tsav los ntawm Francis lossis axial-flow turbines. Cov qauv ntsug tuaj yeem muab faib ua hom ncua thiab hom kaus. Lub thrust bearing ntawm lub tshuab hluav taws xob nyob rau sab saud ntawm lub rotor yog hu ua hom ncua, thiab lub thrust bearing nyob rau sab qis ntawm lub rotor yog hu ua hom kaus.
3) Cov qauv tubular
Lub tshuab hluav taws xob tubular turbine generator unit yog tsav los ntawm lub tubular turbine. Tubular turbine yog ib hom turbine axial-flow tshwj xeeb nrog cov hniav khiav ruaj khov lossis kho tau. Nws lub ntsiab feature yog tias lub runner axis yog teeb tsa kab rov tav lossis obliquely, thiab qhov kev taw qhia ntws yog sib xws nrog cov yeeb nkab nkag thiab qhov tawm ntawm lub turbine. Tubular Hydrogenerator muaj qhov zoo ntawm cov qauv me me thiab lub teeb yuag. Nws yog dav siv hauv cov chaw tsim hluav taws xob nrog lub taub hau dej tsawg.
3, Cov khoom siv ntawm lub tshuab hluav taws xob hydro
Lub tshuab hluav taws xob ntsug feem ntau suav nrog stator, rotor, thav duab sab saud, thav duab qis, lub zog thawb, kev coj ua, cua txias thiab lub zog turbine tas mus li.
