Uma kuqhathaniswa nejenereyitha ye-turbine yomusi, ijenereyitha ye-hydro inezici ezilandelayo:
(1) Ijubane liphansi. Linqunyelwe yikhanda lamanzi, ijubane lokujikeleza ngokuvamile lingaphansi kuka-750r / min, kanti amanye amashumi ambalwa kuphela ngomzuzu.
(2) Inani lezinsika zikagesi likhulu. Ngenxa yokuthi ijubane liphansi, ukuze kukhiqizwe amandla kagesi angu-50Hz, kuyadingeka ukwandisa inani lezinsika zikagesi, ukuze insimu kagesi yokusika i-stator winding isakwazi ukushintsha izikhathi ezingu-50 ngomzuzwana.
(3) Isakhiwo sikhulu ngobukhulu nangesisindo. Ngakolunye uhlangothi, isivinini siphansi; Ngakolunye uhlangothi, uma iyunithi yenqatshwa umthwalo, ukuze kugwenywe ukuqhekeka kwepayipi lensimbi okubangelwa isando samanzi esinamandla, isikhathi sokuvala esiphuthumayo se-guide vane siyadingeka sibe side, kodwa lokhu kuzokwenza ukuthi iyunithi ikhuphuke ngesivinini kakhulu. Ngakho-ke, i-rotor iyadingeka ukuthi ibe nesisindo esikhulu kanye ne-inertia.
(4) I-axis eqondile ivame ukusetshenziswa. Ukuze kuncishiswe ukuhlalwa komhlaba kanye nezindleko zezitshalo, abakhiqizi bamanzi abakhulu nabaphakathi ngokuvamile basebenzisa umgodi oqondile.
Amajeneretha e-hydro angahlukaniswa ngezinhlobo eziqondile nezivundlile ngokwendlela ehlukene yokuhlelwa kwemiphini yawo ejikelezayo: amajeneretha e-hydro avundlile angahlukaniswa ngezinhlobo ezilengayo kanye nezesambulela ngokwezindawo ezahlukene zama-thrust bearings awo.
(1) I-Hydrogenerator Esamisiwe. I-thrust bearing ifakwa maphakathi noma engxenyeni engenhla yohlaka olungaphezulu lwe-rotor, esebenza kahle futhi inakekelwa kalula, kodwa ukuphakama kukhulu futhi imali etshaliwe esitshalweni inkulu.
(2) Ijeneretha ye-Umbrella hydro. I-thrust bearing ifakwa emzimbeni ophakathi noma engxenyeni engenhla yohlaka olungezansi lwe-rotor. Ngokuvamile, amajeneretha amakhulu e-hydro anejubane eliphakathi neliphansi kufanele asebenzise uhlobo lwesambulela ngenxa yobukhulu bawo obukhulu besakhiwo, ukuze anciphise ukuphakama kweyunithi, onge insimbi futhi anciphise ukutshalwa kwezimali kwesitshalo. Eminyakeni yamuva nje, isakhiwo sokufaka i-thrust bearing esembozweni esiphezulu se-water turbine sithuthukisiwe, futhi ukuphakama kweyunithi kungancishiswa.
2. Izingxenye eziyinhloko
Ijeneretha ye-hydro yakhiwe kakhulu yi-stator, i-rotor, i-thrust bearing, ama-guide bearing aphezulu nangaphansi, ozimele abaphezulu nangaphansi, idivayisi yokungenisa umoya nokupholisa, idivayisi yokubhuleka kanye nedivayisi yokuvuselela.
(1) I-Stator. Iyingxenye yokukhiqiza amandla kagesi, akhiwa yi-winding, i-iron core kanye ne-shell. Ngenxa yokuthi ububanzi be-stator bama-hydro generator amakhulu naphakathi bukhulu kakhulu, ngokuvamile buhlanganiswa izingxenye zokuthutha.
(2) I-Rotor. Iyingxenye ejikelezayo ekhiqiza insimu kazibuthe, eyakhiwa ukwesekwa, indandatho yesondo kanye nenduku kazibuthe. Indandatho yesondo iyingxenye ebunjwe njengendandatho eyakhiwe ngepuleti yensimbi ebunjwe njengefeni. Izingongolo kazibuthe zisatshalaliswa ngaphandle kwendandatho yesondo, futhi indandatho yesondo isetshenziswa njengendlela yensimu kazibuthe. Umucu owodwa we-rotor enkulu nephakathi nendawo uhlanganiswa endaweni, bese ushiswa futhi uboshwe emgodleni omkhulu wejeneretha. Eminyakeni yamuva nje, isakhiwo esingenamgodla we-rotor sithuthukisiwe, okungukuthi, ukwesekwa kwe-rotor kuqiniswe ngqo ekugcineni okuphezulu komgodla omkhulu we-turbine. Inzuzo enkulu yalesi sakhiwo ukuthi singaxazulula izinkinga zekhwalithi zokuphonswa okukhulu kanye nokuphonswa okubangelwa yiyunithi enkulu; Ngaphezu kwalokho, kunganciphisa futhi isisindo sokuphakamisa i-rotor kanye nokuphakama kokuphakamisa, ukuze kuncishiswe ukuphakama kwesitshalo futhi kulethe ukonga okuthile ekwakhiweni kwesitshalo samandla.
(3) I-Thrust bearing. Yingxenye ethwala isisindo esiphelele sengxenye ejikelezayo yeyunithi kanye ne-axial hydraulic thrust ye-turbine.
(4) Uhlelo Lokupholisa. I-Hydrogenerator ivame ukusebenzisa umoya njengendawo yokupholisa ukupholisa i-stator, i-rotor winding kanye ne-stator core. Ama-hydro generator amancane avame ukusebenzisa umoya ovulekile noma ohamba ngamapayipi, kuyilapho ama-hydro generator amakhulu naphakathi avame ukusebenzisa umoya ovaliwe ozijikeleza wona. Ukuze kuthuthukiswe ukuqina kokupholisa, amanye ama-hydro generator ane-high power asebenzisa imodi yokupholisa yangaphakathi ye-hollow conductor edlula ngqo endaweni yokupholisa, kanti i-cooling medium isebenzisa amanzi noma i-medium entsha. Ama-stator nama-rotor windings apholiswa ngaphakathi ngamanzi, kanti i-cooling medium iyi-water noma i-medium entsha. Ama-stator nama-rotor windings asebenzisa ukupholisa kwangaphakathi kwamanzi abizwa ngokuthi ukupholisa kwangaphakathi kwamanzi kabili. Ama-stator nama-rotor windings kanye ne-stator core asebenzisa ukupholisa kwangaphakathi kwamanzi abizwa ngokuthi ukupholisa kwangaphakathi kwamanzi agcwele, kodwa ama-stator nama-rotor windings asebenzisa ukupholisa kwangaphakathi kwamanzi abizwa ngokuthi ukupholisa kwangaphakathi kwamanzi agcwele, kodwa ama-stator nama-rotor windings asebenzisa ukupholisa kwangaphakathi kwamanzi abizwa ngokuthi ukupholisa kwangaphakathi kwamanzi aphakathi.
Enye indlela yokupholisa ye-hydro generator ukupholisa ngokuhwamuka, okuxhumanisa i-liquid medium ku-conductor ye-hydro generator ukuze kuphole ngokuhwamuka. Ukupholisa ngokuhwamuka kunezinzuzo zokuthi ukufudumala kwe-thermal medium kukhulu kakhulu kunomoya namanzi, futhi kunganciphisa isisindo nosayizi weyunithi.
(5) Idivayisi yokuvuselela kanye nokuthuthukiswa kwayo kufana kakhulu naleyo yamayunithi wamandla okushisa.
