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 iquka isiseko, i-iron core, kunye ne-windings. I-stator core yenziwe ngamashidi ensimbi ye-silicon epholileyo, enokuthi yenziwe ibe yinto edibeneyo kunye neyokwahlula ngokwemiqathango yokuvelisa kunye nokuthutha. Indlela yokupholisa yejenereyitha yeijinijeyitha yamanzi ngokuqhelekileyo yamkela ukupholisa komoya ojikelezayo ovaliweyo. Iiyunithi ezinomthamo 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 iitekhnoloji ezintsha zamkelwe 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 kweekhoyili ze-stator, i-elastic wedges isetyenziselwa ukubethelwa phantsi kwee-strips ukuthintela 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, i-high-speed generator motors ziquka i-Dinovic Pumped Storage Power Station (330,000 kVA, 500r / min) e-United Kingdom njalo njalo.

Ukusebenzisa ii-motor zangaphakathi zokupholisa zangaphakathi zamanzi amabini, 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 yejenereyitha (425,000 kVA, 300r/min) yeSikhululo saMandla seLa Kongshan Pumped Storage e-United States ikwasebenzisa ukupholisa kwamanzi okubini ngaphakathi.

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