Uma kuqhathaniswa ne-steam turbine generator, i-hydro generator inezici ezilandelayo:
(1) Ijubane liphansi. Inqunyelwe ikhanda lamanzi, isivinini esijikelezayo ngokuvamile singaphansi kuka-750r/min, kanti okunye kuwukuguquguquka okuningi ngomzuzu.
(2) Inani lezigxobo kazibuthe likhulu. Ngenxa yokuthi ijubane liphansi, ukuze kukhiqizwe 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 okubangelwa isando samanzi esinamandla, isikhathi sokuvala esiphuthumayo se-vane yomhlahlandlela sidingeka sibe side, kodwa lokhu kuzobangela ukukhuphuka kwesivinini kweyunithi ibe phezulu kakhulu. Ngakho-ke, i-rotor iyadingeka ukuba ibe nesisindo esikhulu kanye ne-inertia.
(4) I-eksisi eqondile ngokuvamile iyamukelwa. Ukuze kwehliswe izindleko zokuthatha umhlaba nezitshalo, amajeneretha amakhulu naphakathi nendawo ngokuvamile asebenzisa i-shaft eqondile.
Amajeneretha e-Hydro angahlukaniswa abe izinhlobo ezime mpo nezivundlile ngokuya ngohlelo oluhlukile 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, enokusebenza okuzinzile nokugcinwa okulula, kodwa ukuphakama kukhulu futhi ukutshalwa kwezimali kwesitshalo kukhulu.
(2) Umbrella hydro generator. I-thrust bear ifakwe emzimbeni ophakathi noma ingxenye yawo engenhla yohlaka olungezansi lwe-rotor. Ngokuvamile, amajeneretha amakhulu e-hydro anesivinini esimaphakathi nesiphansi kufanele asebenzise uhlobo lwesambulela ngenxa yobukhulu bawo 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 ngama-winging, i-iron core 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 nokuphakamisa ukuphakama, 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 kagesi avame ukusebenzisa umoya ovulekile noma wamapayipi, kuyilapho amajeneretha amakhulu naphakathi nendawo ngokuvamile asebenzisa umoya wokuzihambisa ovaliwe. Ukuze kuthuthukiswe amandla okupholisa, amanye amawindi okuphehla amandla e-hydro enamandla athatha imodi yokupholisa yangaphakathi yekhondatha engenalutho edlula ngokuqondile endaweni epholisayo, nendawo yokupholisa isebenzisa amanzi noma into entsha. I-stator ne-rotor windings ipholiswe ngaphakathi ngamanzi, kanti indawo yokupholisa amanzi noma i-medium entsha. I-stator ne-rotor windings esebenzisa ukupholisa kwangaphakathi kwamanzi kubizwa ngokuthi ukupholisa kwangaphakathi kwamanzi okuphindwe kabili. I-stator kanye ne-rotor windings kanye ne-stator core esebenzisa ukupholisa kwamanzi kubizwa 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 i-liquid medium ku-conductor 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.
