Jenereta ya hydro imapangidwa ndi rotor, stator, chimango, thrust bearing, guide bearing, cooler, brake ndi zigawo zina zazikulu (onani Chithunzi). Stator imapangidwa makamaka ndi chimango, chitsulo, winding ndi zigawo zina. Stator core imapangidwa ndi mapepala achitsulo a silicon ozungulira ozizira, omwe amatha kupangidwa kukhala kapangidwe kogwirizana ndi kogawanika malinga ndi momwe zinthu zimachitikira komanso momwe zimayendera. Jenereta ya turbine yamadzi nthawi zambiri imazizira ndi mpweya wozungulira wotsekedwa. Mayunitsi akuluakulu okhala ndi mphamvu amagwiritsa ntchito madzi ngati malo ozizira kuti aziziritse stator mwachindunji. Ngati stator ndi rotor zitaziritsidwa nthawi imodzi, ndi seti ya jenereta ya mawilo ozizira amkati mwa madzi awiri.
Pofuna kukweza mphamvu ya unit imodzi ya hydro generator ndikupangitsa kuti ikhale unit yayikulu, ukadaulo watsopano wambiri umagwiritsidwa ntchito kuti ukhale wodalirika komanso wolimba. Mwachitsanzo, pofuna kuthetsa kufalikira kwa kutentha kwa stator, kapangidwe ka stator koyandama ndi chithandizo chopendekeka zimagwiritsidwa ntchito, ndipo rotor imagwiritsa ntchito kapangidwe ka disc. Pofuna kuthetsa kusasunthika kwa stator coil, cushion strip pansi pa elastic wedge imagwiritsidwa ntchito kuti ipewe kutayika kwa insulation kwa waya. Kuwongolera kapangidwe ka mpweya ndikuchepetsa kutayika kwa mphepo ndi kutayika kwa eddy current kuti ipititse patsogolo magwiridwe antchito a unit.
Ndi chitukuko cha ukadaulo wopanga ma turbine opompa, liwiro ndi mphamvu ya injini ya jenereta zikuwonjezekanso, zomwe zikukula kufika pamphamvu yayikulu komanso liwiro lalikulu. Malo osungira mphamvu omangidwa okhala ndi ma mota amphamvu komanso amphamvu kwambiri padziko lonse lapansi akuphatikizapo malo osungira magetsi opompa a dinowick (330000 KVA, 500r / min) ku UK.
Malire opangira injini ya jenereta akhoza kukonzedwa pogwiritsa ntchito injini ya jenereta yoziziritsira mkati mwa madzi awiri, ndipo coil ya stator, coil ya rotor ndi stator core zimaziritsidwa mkati mwachindunji ndi madzi a ionic. Mota ya jenereta (425000 KVA, 300r / min) ya malo osungira magetsi opompedwa a lakongshan ku United States imagwiritsanso ntchito kuziziritsa mkati mwa madzi awiri.
Kugwiritsa ntchito mphamvu ya magnetic thrust bearing. Pamene mphamvu ya injini ya jenereta ikuwonjezeka komanso liwiro lake, mphamvu ya thrust ndi starting torque ya unit zikuwonjezekanso. Pambuyo poti mphamvu ya magnetic thrust bearing yagwiritsidwa ntchito, chifukwa cha mphamvu ya maginito yotsutsana ndi mphamvu yokoka, mphamvu ya thrust imachepetsa mphamvu ya thrust bearing, imachepetsa kutayika kwa shaft surface resistance, imachepetsa kutentha kwa bearing, imapangitsa kuti unit igwire bwino ntchito, komanso imachepetsa nthawi yoyambira kukana.
