Momwe Mungasinthire Kudalirika ndi Kukhazikika kwa Hydro Jenereta

Jenereta ya Hydro imapangidwa ndi rotor, stator, chimango, thrust bear, kalozera, ozizira, mabuleki ndi zigawo zina zazikulu (onani Chithunzi).The stator makamaka wapangidwa chimango, chitsulo pakati, mapiringidzo ndi zigawo zina.Pakatikati pa stator amapangidwa ndi zitsulo zachitsulo zoziziritsa kuzizira za silicon, zomwe zimatha kupangidwa kuti zikhale zophatikizika komanso zogawanika molingana ndi momwe zimapangidwira komanso zoyendera.Jenereta ya turbine yamadzi nthawi zambiri imakhazikika ndi mpweya wotsekedwa.Mayunitsi akulu akulu amakonda kugwiritsa ntchito madzi ngati sing'anga yozizira kuti aziziziritsa stator.Pamene stator ndi rotor ndi utakhazikika pa nthawi yomweyo, ndi awiri madzi mkati kuzirala gudumu jenereta seti.

Pofuna kupititsa patsogolo mphamvu ya unit imodzi ya hydro jenereta ndikukula kukhala chimphona chachikulu, matekinoloje ambiri atsopano amatengedwa kuti apititse patsogolo kudalirika kwake komanso kukhazikika.Mwachitsanzo, kuti athetse kufalikira kwa matenthedwe a stator, mawonekedwe oyandama a stator ndi chithandizo chokhazikika amagwiritsidwa ntchito, ndipo rotor imatengera kapangidwe ka disc.Pofuna kuthetsa kutayikira kwa koyilo ya stator, chingwe cha khushoni pansi pa mphero zotanuka chimagwiritsidwa ntchito poletsa kuvala kwa waya.Limbikitsani mpweya wabwino ndikuchepetsa kutayika kwa mphepo komanso kutayika kwa eddy pano kuti mupititse patsogolo magwiridwe antchito a unit.

Ndi chitukuko cha makina opangira makina opangira makina opangira makina, kuthamanga ndi mphamvu ya injini ya jenereta zikuchulukirachulukira, kukhala ndi mphamvu zambiri komanso kuthamanga kwambiri.Malo opangira magetsi osungiramo mphamvu okhala ndi mphamvu zazikulu komanso ma mota othamanga kwambiri padziko lonse lapansi akuphatikiza dinowick pumped storage power station (330000 KVA, 500r / min) ku UK.

Kugwiritsa ntchito injini yamagetsi yozizirira yamadzi iwiri yamkati, koyilo ya stator, coil ya rotor ndi stator core zimakhazikika mkati ndi madzi a ionic, omwe amatha kupititsa patsogolo malire opanga ma jenereta.Galimoto ya jenereta (425000 KVA, 300r / min) ya lalongshan pumped storage power station ku United States imatenganso kuziziritsa kwamadzi kawiri mkati.

Kugwiritsa ntchito maginito thrust bearing.Ndi kuchuluka kwa mphamvu zamagalimoto a jenereta komanso liwiro, kuthamangitsa komanso ma torque oyambira a unit akuchulukiranso.Pambuyo pogwiritsira ntchito maginito, mphamvu yowonjezera imawonjezera kukopa kwa maginito kumbali ina ya mphamvu yokoka, yomwe imachepetsa katundu wa gwero, imachepetsa kutayika kwa shaft pamwamba kukana, imachepetsa kutentha kwapakati ndikuwonjezera mphamvu ya unit, ndi kuyambira mphindi yotsutsa imachepetsedwanso.Magnetic thrust bearing amatengera injini ya jenereta (335000 KVA, 300r / min) ya sanglangjing pumped storage power station ku South Korea.
