I-hydro-generator yakhiwe nge-rotor, i-stator, ifreyimu, i-thrust bear, i-guide bear, i-cooler, i-brake nezinye izingxenye eziyinhloko (bheka isithombe).I-stator ikakhulukazi yakhiwe isisekelo, i-iron core, nama-windings.I-stator core yenziwe ngamashidi ensimbi ye-silicon egoqwe abandayo, angenziwa abe yisakhiwo esibalulekile nesihlukanisayo ngokuya ngezimo zokukhiqiza nezokuthutha.Indlela yokupholisa yejeneretha ye-turbine yamanzi ngokuvamile isebenzisa ukupholisa komoya okuvalekile.Amayunithi anomthamo omkhulu avame ukusebenzisa amanzi njengendawo yokupholisa ukuze apholise ngokuqondile i-stator.Uma i-stator ne-rotor zipholile ngesikhathi esifanayo, isethi yamanzi amabili apholile ngaphakathi ejeneretha yejeneretha yamanzi.
Ukuze kwandiswe umthamo weyunithi eyodwa ye-hydro-generator futhi ithuthuke ibe yiyunithi enkulu, ukuze kuthuthukiswe ukuthembeka nokuqina kwayo, ubuchwepheshe obuningi obusha semukelwe esakhiweni.Isibonelo, ukuze kuxazululwe ukunwetshwa kokushisa kwe-stator, isakhiwo esintantayo se-stator, ukusekelwa kwe-oblique, njll kuyasetshenziswa, futhi i-rotor ithatha isakhiwo se-disc.Ukuze kuxazululwe ukuxega kwamakhoyili e-stator, ama-elastic wedge asetshenziselwa ukumboza imichilo ukuze kuvinjelwe ukuguga kwezintambo zocingo.Thuthukisa isakhiwo sokungenisa umoya ukuze unciphise ukulahlekelwa komoya futhi uqede ukulahlekelwa kwamanje kwe-eddy ukuze uthuthukise ukusebenza kahle kweyunithi.
Ngokuthuthukiswa kobuchwepheshe bokukhiqiza i-turbine yephampu yamanzi, isivinini namandla ama-generator motors nawo ayanda, athuthukela kumthamo omkhulu kanye nesivinini esikhulu.Emhlabeni, iziteshi zamandla ezigciniwe ezakhiwe ezifakwe amandla amakhulu, ama-generator motors anesivinini esikhulu zihlanganisa i-Dinovic Pumped Storage Power Station (330,000 kVA, 500r / min) e-United Kingdom njalonjalo.
Ukusebenzisa ama-motor angaphakathi okupholisa angaphakathi okupholisa amanzi amabili, ikhoyili ye-stator, ikhoyili ye-rotor kanye ne-stator core zipholiswa ngokuqondile ngaphakathi ngamanzi ane-ionized, angandisa umkhawulo wokukhiqiza we-generator motor.Ijeneretha motor (425,000 kVA, 300r/min) yeSiteshi Samandla Sesitoreji SePumped La Kongshan e-United States futhi isebenzisa ukupholisa kwamanzi okukabili kwangaphakathi.
Ukusetshenziswa kwamagnetic thrust bearings.Njengoba umthamo we-generator motor ukhula, ijubane liyakhula, kanjalo nomthwalo we-thrust kanye ne-torque yokuqala yeyunithi.Ngemuva kokusebenzisa i-magnetic thrust bearing, umthwalo we-thrust wengezwa ngokukhanga kazibuthe ngakolunye uhlangothi lwe-gravity, ngaleyo ndlela kuncishiswe umthwalo othwala i-thrust, ukunciphisa ukulahlekelwa ukumelana ne-axial, ukunciphisa izinga lokushisa kanye nokwenza ngcono ukusebenza kahle kweyunithi, kanye ukuqala ukumelana Umzuzu nawo uyancipha.I-generator motor (335,000 kVA, 300r/min) ye-Sanglangjing Pumped Storage Power Station e-South Korea isebenzisa ama-thrust bearings kazibuthe.
