Uma kuqhathaniswa nejeneretha ye-steam turbine, i-hydro generator inezici ezilandelayo:
(1) Ijubane liphansi.Inqunyelwe ikhanda lamanzi, isivinini esijikelezayo ngokuvamile singaphansi kuka-750r / min, kanti ezinye zingama-revolutions amaningi ngomzuzu.
(2) Inani lezigxobo kazibuthe likhulu.Ngenxa yokuthi ijubane liphansi, ukuze ukhiqize amandla kagesi angu-50Hz, kuyadingeka ukwandisa inani lezigxobo kazibuthe, ukuze indawo kazibuthe yokusika i-stator winding isengakwazi ukushintsha izikhathi ezingu-50 ngomzuzwana.
(3) Isakhiwo sikhulu ngobukhulu nesisindo.Ngakolunye uhlangothi, ijubane liphansi;Ngakolunye uhlangothi, uma kwenzeka ukwenqatshwa komthwalo weyunithi, ukuze kugwenywe ukugqashuka kwepayipi lensimbi elibangelwa isando samanzi esinamandla, isikhathi sokuvala esiphuthumayo se-guide vane siyadingeka ukuba sibe side, kodwa lokhu kuzodala ukukhuphuka kwejubane iyunithi ukuthi ibe phezulu kakhulu.Ngakho-ke, i-rotor iyadingeka ukuba ibe nesisindo esikhulu kanye ne-inertia.
(4) I-eksisi eqondile ngokuvamile iyamukelwa.Ukuze kwehliswe izindleko zokuhlala nezindleko zezitshalo, amajeneretha amakhulu naphakathi nendawo ngokuvamile asebenzisa i-shaft eqondile.
Amajeneretha e-Hydro angahlukaniswa abe izinhlobo ezime mpo nezivundlile ngokuya ngohlelo oluhlukene lwamashafu awo azungezayo: amajeneretha e-hydro aqondile angahlukaniswa abe izinhlobo ezimisiwe kanye nezambulela ngokuya ngezindawo ezihlukene zama-thrust bearings.
(1) I-Hydrogenerator Emisiwe.I-thrust bear ifakwe phakathi nendawo noma engxenyeni engenhla yohlaka olungaphezulu lwe-rotor, elinokusebenza okuzinzile nokunakekelwa okufanele, kodwa ukuphakama kukhulu futhi ukutshalwa kwezimali kwesitshalo kukhulu.
(2) Umbrella hydro generator.I-thrust bear ifakwe emzimbeni ophakathi nendawo noma engxenyeni yawo engenhla yohlaka olungezansi lwe-rotor.Ngokuvamile, amajeneretha amakhulu e-hydro anesivinini esimaphakathi nesiphansi kufanele asebenzise uhlobo lwesambulela ngenxa yobukhulu bawo obukhulu besakhiwo, ukuze kuncishiswe ukuphakama kweyunithi, onge insimbi futhi kuncishiswe ukutshalwa kwezimali kwezitshalo.Eminyakeni yamuva nje, isakhiwo sokufaka i-thrust bear phezu kwekhava ephezulu ye-turbine yamanzi senziwe, futhi ukuphakama kweyunithi kungancishiswa.
2. Izingxenye eziyinhloko
Ijeneretha ye-Hydro ikakhulukazi yakhiwa i-stator, i-rotor, i-thrust bear, ama-guide bearings aphezulu naphansi, amafreyimu aphezulu naphansi, idivayisi yokukhipha umoya neyokupholisa, idivayisi yokubhuleka kanye nedivayisi evusa amadlingozi.
(1) I-Stator.Iyingxenye yokukhiqiza amandla kagesi, akhiwe ngokujikajika, umgogodla wensimbi kanye negobolondo.Ngenxa yokuthi ububanzi be-stator bamajeneretha e-hydro amakhulu naphakathi bukhulu kakhulu, ngokuvamile bakhiwa izingxenye zokuthutha.
(2) Irotha.Iyingxenye ejikelezayo ekhiqiza inkambu kazibuthe, eyakhiwe ukwesekwa, iringi yamasondo nesigxobo kazibuthe.Iringi yesondo iyisakhi esimise okwendandatho esakhiwe nge- iron plate emise okwefeni.Izigxobo kazibuthe zisakazwa ngaphandle kweringi yesondo, futhi indandatho yesondo isetshenziswa njengendlela yensimu kazibuthe.I-strand eyodwa ye-rotor enkulu nephakathi nendawo ihlanganiswe esizeni, bese ifudumala futhi ifakwe emikhono ku-shaft eyinhloko ye-generator.Eminyakeni yamuva nje, kuye kwathuthukiswa isakhiwo se-rotor shaftless, okungukuthi, ukusekelwa kwe-rotor kugxilwe ngokuqondile ekupheleni kwe-shaft eyinhloko ye-turbine.Inzuzo enkulu yalesi sakhiwo ukuthi ingakwazi ukuxazulula izinkinga zekhwalithi ze-castings ezinkulu kanye ne-forgings ebangelwa iyunithi enkulu;Ngaphezu kwalokho, kungase futhi kunciphise isisindo sokuphakamisa i-rotor nokuphakama kokuphakamisa, ukuze kuncishiswe ukuphakama kwesitshalo futhi kulethe umnotho othile ekwakhiweni kwesitshalo samandla.
(3) I-thrust bear.Iyingxenye ethwala isisindo esiphelele sengxenye ejikelezayo yeyunithi kanye ne-axial hydraulic thrust ye-turbine.
(4) Uhlelo lokupholisa.IHydrogenerator ivamise ukusebenzisa umoya njengendawo yokupholisa ukupholisa i-stator, i-rotor winding kanye ne-stator core.Amajeneretha amancane ka-hydro ngokuvamile asebenzisa umoya ovulekile noma wamapayipi, kuyilapho amajeneretha amakhulu naphakathi nendawo ngokuvamile asebenzisa umoya wokuzihambisa okuvaliwe.Ukuze kuthuthukiswe amandla okupholisa, amanye amawindi okuphehla amandla e-hydro enamandla athatha imodi yokupholisa yangaphakathi yekhondatha engenalutho edlula ngokuqondile endaweni yokupholisa, nendawo yokupholisa isebenzisa amanzi noma into entsha.I-stator ne-rotor windings ipholile ngaphakathi emanzini, kanti indawo yokupholisa amanzi noma i-medium entsha.I-stator kanye ne-rotor windings esebenzisa ukupholisa kwangaphakathi kwamanzi kubizwa ngokuthi ukupholisa kwangaphakathi kwamanzi okuphindwe kabili.I-stator kanye ne-rotor windings kanye ne-stator core ezithatha ukupholisa kwamanzi zibizwa ngokuthi ukupholisa okugcwele kwamanzi kwangaphakathi, kodwa ama-stator kanye nama-rotor windings amukela ukupholisa kwangaphakathi kwamanzi abizwa ngokuthi ukupholisa kwangaphakathi kwamanzi okuyingxenye.
Enye indlela yokupholisa ye-hydro generator ukupholisa okuhwamukayo, okuxhuma uketshezi oluphakathi nekhondatha ye-hydro generator ukuze kuphole ukuhwamuka.Ukupholisa okuhwamukayo kunezinzuzo zokuthi i-thermal conductivity yendawo yokupholisa inkulu kakhulu kunomoya namanzi, futhi inganciphisa isisindo nosayizi weyunithi.
(5) Ithuluzi elivusa amadlingozi nokuthuthukiswa kwalo ngokuyisisekelo kuyafana nalezo zamayunithi amandla ashisayo.
