1, Kev faib cov peev txheej thiab qib ntawm hydrogenerator
Tam sim no, tsis muaj ib qho kev sib koom ua ke rau kev faib cov peev txheej thiab kev ceev ntawm lub tshuab hluav taws xob hauv ntiaj teb. Raws li qhov xwm txheej hauv Suav teb, nws lub peev xwm thiab kev nrawm tuaj yeem sib cais raws li cov lus hauv qab no:
Kev faib hluav taws xob ntsuas hluav taws xob PN (kw) ntsuas ceev NN (R / min);
Tsawg ceev, nruab nrab ceev thiab siab ceev;
Micro hydrogenerator <100 750-1500;
Lub tshuab hluav taws xob me me 100-500 < 375-600 750-1500;
Nruab nrab loj hydro generator 500-10000 < 375-600 750-1500; Lub tshuab hluav taws xob loj loj> 10000 < 100-375> 375;
2 、 Kev teeb tsa qauv hom hydro generator
Lub installation qauv ntawm hydro generator feem ntau yog txiav txim los ntawm hom hydraulic turbine. Muaj ntau hom hauv qab no:
1) Kab rov tav qauv
Hydro generators nrog kab rov tav qauv feem ntau yog tsav los ntawm impulse turbines. Kab rov tav dej turbine units feem ntau yog siv ob lossis peb cov kabmob. Cov qauv ntawm ob bearings muaj qhov zoo ntawm luv axial ntev, compact qauv thiab yooj yim installation thiab hloov. Txawm li cas los xij, thaum qhov ceev ceev ntawm lub shafting tsis tuaj yeem ua tau raws li qhov yuav tsum tau ua lossis cov kabmob load loj, peb cov kabmob yuav tsum tau txais yuav. Feem ntau domestic hydraulic turbine generator units yog rau me me thiab nruab nrab-qhov loj me. Cov kab rov tav loj nrog lub peev xwm ntawm 12.5mw kuj tau tsim. Kab rov tav dej turbine generator units tsim tawm txawv teb chaws tsis tshua muaj peev xwm ntawm 60-70mw, thaum kab rov tav dej turbine generator units nrog cov twj tso kua mis cia fais fab tuaj yeem muaj peev xwm ntawm 300MW.
2) Vertical qauv
Vertical qauv yog dav siv nyob rau hauv domestic dej turbine generator units. Vertical water turbine generator units feem ntau yog tsav los ntawm Francis lossis axial-flow turbines. Cov qauv ntsug tuaj yeem muab faib ua hom ncua kev kawm thiab hom kaus. Lub thrust bearing ntawm lub tshuab hluav taws xob nyob rau sab sauv ntawm lub rotor yog sib sau ua ke hu ua hom raug tshem tawm, thiab cov kabmob thrust nyob rau hauv qis ntawm lub rotor yog sau ua ke hu ua kaus mom.
3) Tubular qauv
Tubular turbine generator chav tsev yog tsav los ntawm tubular turbine. Tubular turbine yog ib hom tshwj xeeb ntawm axial-flow turbine nrog kev ruaj khov lossis hloov tau khiav cov hniav. Nws lub ntsiab feature yog hais tias tus khiav axis yog teem horizontally los yog obliquely, thiab cov kev taw qhia ntws yog raws li nyob rau hauv cov yeeb nkab inlet thiab qhov hluav taws xob yeeb nkab ntawm lub turbine. Tubular Hydrogenerator muaj qhov zoo ntawm cov qauv compact thiab lub teeb yuag. Nws yog dav siv hauv cov chaw nres tsheb fais fab nrog lub taub dej qis.
3, Cov yam ntxwv ntawm cov tshuab hluav taws xob hydro
Vertical hydro generator feem ntau suav nrog stator, rotor, sab sauv ncej, qis ncej, thrust bearing, coj bearing, cua txias thiab cov hlau nplaum ruaj khov turbine.
