I-hydro-generator yakhiwe nge-rotor, i-stator, uhlaka, i-thrust bearing, i-guide bearing, i-cooler, i-brake nezinye izingxenye eziyinhloko (bheka isithombe). I-stator yakhiwe kakhulu ngesisekelo, i-iron core, kanye nama-windings. I-stator core yenziwe ngamashidi ensimbi e-silicon aqoqwe ngokubandayo, angenziwa abe yisakhiwo esihlanganisiwe nesihlukanisiwe ngokwezimo zokukhiqiza nezokuthutha. Indlela yokupholisa ye-water turbine generator ngokuvamile isebenzisa ukupholisa komoya ojikelezayo okuvaliwe. Amayunithi amakhulu avame ukusebenzisa amanzi njengendawo yokupholisa ukupholisa i-stator ngqo. Uma i-stator ne-rotor zipholiswa ngesikhathi esifanayo, iyisethi ye-water turbine generator epholiswe ngamanzi amabili ngaphakathi.
Ukuze kwandiswe umthamo weyunithi eyodwa ye-hydro-generator futhi ithuthuke ibe yiyunithi enkulu, ukuze kuthuthukiswe ukuthembeka kwayo nokuqina kwayo, kuye kwamukelwa ubuchwepheshe obusha obuningi esakhiweni. Isibonelo, ukuze kuxazululwe ukwanda kokushisa kwe-stator, kusetshenziswa isakhiwo esintantayo se-stator, ukwesekwa okugobile, njll., futhi i-rotor isebenzisa isakhiwo sediski. Ukuze kuxazululwe ukukhululeka kwama-coil e-stator, kusetshenziswa ama-wedge e-elastic ukuze kufakwe ngaphansi kwemigqa ukuze kuvinjelwe ukufudumala kwezinduku zensimbi ukuthi zingagugi. Thuthukisa isakhiwo sokungenisa umoya ukuze kuncishiswe ukulahleka komoya kanye nokulahlekelwa kokuphela komshini we-eddy ukuze kuthuthukiswe ukusebenza kahle kweyunithi.
Ngokuthuthuka kobuchwepheshe bokukhiqiza i-turbine yamaphampu amanzi, isivinini kanye nomthamo wama-motor e-generator nakho kuyakhula, kuthuthukela kumthamo omkhulu kanye nesivinini esikhulu. Emhlabeni, iziteshi zamandla zokugcina ezakhiwe ezihlonyiswe ngama-motor e-generator amakhulu, anesivinini esikhulu zifaka phakathi i-Dinovic Pumped Storage Power Station (330,000 kVA, 500r/min) e-United Kingdom njalo njalo.
Kusetshenziswa ama-motor e-generator okupholisa ngaphakathi kwamanzi amabili, i-stator coil, i-rotor coil kanye ne-stator core kupholiswa ngaphakathi ngqo ngamanzi ane-ionized, okungandisa umkhawulo wokukhiqiza we-generator motor. I-generator motor (425,000 kVA, 300r/min) ye-La Kongshan Pumped Storage Power Station e-United States nayo isebenzisa ukupholisa ngaphakathi kwamanzi amabili.
Ukusetshenziswa kwama-magnetic thrust bearings. Njengoba umthamo wenjini yejeneretha ukhula, isivinini siyanda, kanjalo nomthwalo we-thrust kanye ne-start torque yeyunithi. Ngemva kokusebenzisa i-magnetic thrust bearing, umthwalo we-thrust wengezwa ngokukhanga kwe-magnetic ngakolunye uhlangothi lokudonsa phansi, ngaleyo ndlela kunciphisa umthwalo we-thrust bearing, kunciphisa ukulahlekelwa kwe-axial resistance, kunciphisa izinga lokushisa le-bearing futhi kuthuthukiswe ukusebenza kahle kweyunithi, kanye nokumelana kokuqala. Umzuzu nawo uyancipha. Injini yejeneretha (335,000 kVA, 300r/min) yeSiteshi Sikagesi Esinomshini Wokugada I-Sanglangjing eSouth Korea isebenzisa ama-magnetic thrust bearings.
