Xa kuthelekiswa nejenereyitha yeinjini yomphunga, i-hydro generator inezi mpawu zilandelayo:
(1) Isantya siphantsi.Ilinganiselwe yintloko yamanzi, isantya esijikelezayo sihlala singaphantsi kwe-750r / min, kwaye ezinye zimbalwa kuphela iinguqu ngomzuzu.
(2) Inani leepali zemagnethi likhulu.Ngenxa yokuba isantya siphantsi, ukuze kuveliswe amandla ombane angama-50Hz, kuyafuneka ukuba kwandiswe inani leepali zemagnethi, ukuze i-magnetic field of cutting stator winding isenokutshintsha amaxesha angama-50 ngomzuzwana.
(3) Isakhiwo sikhulu ngobukhulu kunye nobunzima.Kwelinye icala, isantya siphantsi;Ngakolunye uhlangothi, kwimeko yokwaliwa komthwalo weyunithi, ukwenzela ukuba kuthintelwe ukugqabhuka kombhobho wentsimbi okubangelwa isando samanzi esinamandla, ixesha lokuvala likaxakeka lesikhokelo se-vane kufuneka libe lide, kodwa oku kuya kubangela ukunyuka kwesantya. iyunithi ukuba phezulu kakhulu.Ngoko ke, i-rotor iyadingeka ukuba ibe nobunzima obukhulu kunye ne-inertia.
(4) I-axis ethe nkqo yamkelwa ngokubanzi.Ukuze kuncitshiswe ukusebenza komhlaba kunye neendleko zezityalo, iijenereyitha ezinkulu neziphakathi zamanzi zidla ngokuthatha ishaft ethe nkqo.
Iijenereyitha zeHydro zinokwahlulwa zibe ziindidi ezithe nkqo nezithe tyaba ngokolungiselelo olwahlukileyo lweeshafti zazo ezijikelezayo: iijenereyitha ze-hydro ezithe nkqo zinokwahlulwa zibe ziintlobo ezinqunyanyisiweyo kunye neeambrela ngokweendawo ezahlukeneyo zeebheringi zazo.
(1) I-Hydrogenerator emisiweyo.I-thrust bear ifakwe phakathi okanye inxalenye ephezulu yesakhelo esiphezulu se-rotor, enomsebenzi ozinzileyo kunye nokugcinwa okufanelekileyo, kodwa ukuphakama kukhulu kwaye utyalo-mali lwesityalo lukhulu.
(2) Umbrella hydro generator.I-thrust bear ifakwe kumzimba ophakathi okanye inxalenye yayo ephezulu yesakhelo esisezantsi se-rotor.Ngokuqhelekileyo, iijeneretha ezinkulu ze-hydro kunye nesantya esiphakathi kunye nesantya esiphantsi kufuneka zithathe uhlobo lwe-ambrela ngenxa yobukhulu besakhiwo, ukwenzela ukunciphisa ubude beyunithi, ukugcina intsimbi kunye nokunciphisa utyalo-mali lwezityalo.Kwiminyaka yakutshanje, isakhiwo sokufakela i-thrust bearing kwi-cover top of the turbine yamanzi iye yaphuhliswa, kwaye ukuphakama kweyunithi kungancitshiswa.
2. Amacandelo aphambili
Ijenereyitha yeHydro ikakhulu yenziwe ngestator, rotor, thrust bearing, iibheringi zesikhokelo eziphezulu nezisezantsi, iifreyimu eziphezulu nezisezantsi, umoya kunye nesixhobo sokupholisa, isixhobo sokuqhobosha kunye nesixhobo sokuvuselela.
(1) Stator.Lilungu lokuvelisa amandla ombane, elenziwe ngokujija, undoqo wentsimbi kunye neqokobhe.Ngenxa yokuba i-stator diameter yeejenereyitha ze-hydro ezinkulu neziphakathi zikhulu kakhulu, ngokuqhelekileyo zenziwe ngamacandelo othutho.
(2) Irotha.Yinxalenye ejikelezayo evelisa umhlaba wemagnethi, oquka inkxaso, ivili kunye nepoleni yemagnethi.Iringi yevili licandelo elimise okwesangqa elenziwe ngepleyiti yentsimbi emile okwefeni.Iipali zemagneti zisasazwa ngaphandle kweringi yevili, kwaye i-wheel ring isetyenziswa njengendlela yemagnethi.I-strand enye ye-rotor enkulu kunye ne-medium-size ihlanganiswe kwisayithi, kwaye emva koko ishushu kwaye ifakwe kwi-shaft ephambili ye-generator.Kwiminyaka yakutshanje, i-rotor shaftless structure iye yaphuhliswa, oko kukuthi, inkxaso ye-rotor igxininiswe ngokuthe ngqo kwinqanaba eliphezulu le-shaft ephambili ye-turbine.Inzuzo enkulu yolu lwakhiwo kukuba inokusombulula iingxaki zomgangatho we-castings enkulu kunye ne-forgings ebangelwa yiyunithi enkulu;Ukongeza, kunokunciphisa ubunzima bokuphakamisa i-rotor kunye nokuphakamisa ukuphakama, ukuze kuncitshiswe ukuphakama kwesityalo kunye nokuzisa uqoqosho oluthile kulwakhiwo lweplanti yamandla.
(3) Ukutyhalela phambili.Lilungu elithwala ubunzima bubonke benxalenye ejikelezayo yeyunithi kunye ne-axial hydraulic thrust ye-injini yomoya.
(4) Inkqubo yokupholisa.I-Hydrogenerator idla ngokusebenzisa umoya njengendlela yokupholisa ukupholisa i-stator, i-rotor winding kunye ne-stator core.Iijenereyitha ezinomthamo omncinci we-hydro zihlala zisebenzisa umoya ovulekileyo okanye wemibhobho, ngelixa iijenereyitha ezinkulu kunye neziphakathi zamanzi zihlala zisebenzisa umoya ozivalekileyo wokuzijikelezisa.Ukuze kuphuculwe amandla okupholisa, amajiko-jiko athile ejenereyitha ye-hydro yomthamo ophezulu amkela imowudi yangaphakathi yokupholisa ye-conductor engumngxuma edlula ngokuthe ngqo kwisiphakathi sokupholisa, kwaye isiphakathi sokupholisa samkela amanzi okanye isiphakathi esitsha.I-stator kunye ne-rotor windings zifakwe ngaphakathi zipholile ngamanzi, kwaye indawo yokupholisa ngamanzi okanye i-medium entsha.I-stator kunye ne-rotor windings eyamkela ukupholisa kwamanzi kwangaphakathi kuthiwa ukupholisa kwangaphakathi kwamanzi kabini.I-stator kunye ne-rotor windings kunye ne-stator core eyamkela ukupholisa kwamanzi kuthiwa yi-cooling yangaphakathi yamanzi epheleleyo, kodwa i-stator kunye ne-rotor windings eyamkela ukupholisa kwamanzi kwangaphakathi kuthiwa yi-semi-internal cooling.
Enye indlela yokupholisa ye-hydro generator kukupholisa okuphuma umphunga, okuqhagamshela indawo yolwelo kwi-conductor ye-hydro generator ukwenzela ukupholisa okuphuma umphunga.Ukupholisa kwe-Evaporative kunenzuzo yokuba i-thermal conductivity yendawo yokupholisa inkulu kakhulu kunomoya kunye namanzi, kwaye inokunciphisa ubunzima kunye nobukhulu beyunithi.
(5) Isixhobo sokuvuselela kunye nophuhliso lwaso ngokusisiseko ziyafana nezo zeyunithi zamandla obushushu.
