Indlela yokuphucula ukuthembeka kunye nokuqina kweejenereyitha ze-injini yamanzi

I-hydro-generator yenziwe nge-rotor, i-stator, isakhelo, i-thrust bear, i-guide bear, i-cooler, i-brake kunye nezinye izinto eziphambili (jonga umfanekiso).I-stator ubukhulu becala yenziwe ngesiseko, intsimbi engundoqo, kunye namajiko-jiko.I-stator core yenziwe ngamashidi ensimbi ye-silicon epholileyo, enokuthi yenziwe ibe yinto edibeneyo kunye neyokwahlula ngokwemiqathango yokuvelisa kunye nokuthutha.Indlela yokupholisa yejenereyitha yeijini yamanzi ngokuqhelekileyo isebenzisa ukupholisa komoya okuvalekileyo ojikelezayo.Iiyunithi zomthamo omkhulu zikholisa ukusebenzisa amanzi njengendawo yokupholisa ukupholisa ngokuthe ngqo i-stator.Ukuba i-stator kunye ne-rotor zipholile ngexesha elifanayo, ngamanzi amabini angaphakathi apholiselwe ngaphakathi kwiseti yejenereyitha ye-iturbine.

Ukuze kwandiswe umthamo weyunithi enye ye-hydro-generator kwaye uphuhlise ibe yiyunithi enkulu, ukwenzela ukuba kuphuculwe ukuthembeka kwayo kunye nokuqina kwayo, ezininzi iteknoloji entsha yamkelwe kwisakhiwo.Ngokomzekelo, ukwenzela ukusombulula ukwanda kwe-thermal ye-stator, isakhiwo esijikelezayo se-stator, inkxaso ye-oblique, njl., kwaye i-rotor ithatha isakhiwo se-disc.Ukuze ucombulule ukukhululeka kwee-coil ze-stator, i-elastic wedges isetyenziselwa ukubethelwa phantsi kweentambo zokuthintela ukugquma kweentambo zocingo ukuba ziguge.Ukuphucula ubume bokuphuma komoya ukunciphisa ilahleko yomoya kunye nokuphelisa ilahleko yangoku ye-eddy ukuphucula ngakumbi ukusebenza kakuhle kweyunithi.

Ngophuhliso lwetekhnoloji yokwenziwa kwempompo yeinjini yempompo yamanzi, isantya kunye nomthamo weenjini zejenereyitha nazo ziyanda, ziphuhlisa kumthamo omkhulu kunye nesantya esiphezulu.Ehlabathini, izikhululo zamandla ezakhiweyo ezixhotyiswe ngomthamo omkhulu, iinjini ze-generator ezikhawulezayo ziquka i-Dinovic Pumped Storage Power Station (330,000 kVA, 500r / min) e-United Kingdom njalo njalo.

Ukusebenzisa iinjini zokupholisa zangaphakathi zamanzi amabini angaphakathi, i-stator coil, i-rotor coil kunye ne-stator core zifakwe ngokuthe ngqo ngaphakathi ngaphakathi ngamanzi e-ionized, enokunyusa umda wokuvelisa i-motor generator.Injini yejeneretha (425,000 kVA, 300r/min) yeSikhululo saMandla sokuPhuma saMandla saseLa Kongshan e-United States sikwasebenzisa ukupholisa kwamanzi angaphakathi kabini.

Ukusetyenziswa kweebheringi zemagnethi.Njengoko umthamo wenjini yejeneretha usanda, isantya siyanda, ngokunjalo nomthwalo wokutyhala kunye nokuqalisa itorque yeyunithi.Emva kokusebenzisa i-magnetic thrust bearing, umthwalo wethrust wongezwa kunye nomtsalane wamagnetic kwicala elichasene nomxhuzulane, ngaloo ndlela unciphisa umthwalo othwele i-thrust, ukunciphisa ilahleko yokumelana ne-axial, ukunciphisa ubushushu bokuthwala kunye nokuphucula ukusebenza kakuhle kweyunithi, kunye ukuqala ukumelana Umzuzu nawo uyancipha.Injini yejenereyitha (335,000 kVA, 300r/min) yeSikhululo saMandla seSanglangjing Pumped Storage eMzansi Korea sisebenzisa iibheringi zemagnethi.
