Kana tichienzanisa nejenareta yeturbine yemhepo ine simba, jenareta yemvura ine hunhu hunotevera:
(1) Kumhanya kwacho kwakaderera. Kunogumira pamvura, kumhanya kwekutenderera kunowanzova pasi pe750r / min, uye kumwe kunongova kutenderera kwakawanda paminiti.
(2) Huwandu hwemapore emagnetic hwakakura. Nekuti kumhanya kwacho kwakaderera, kuti pave nesimba remagetsi re50Hz, zvakakosha kuwedzera huwandu hwemapore emagnetic, kuitira kuti simba remagnetic rekucheka stator winding rigone kuchinja ka50 pasekondi.
(3) Chivako chacho chakakura muhukuru uye huremu. Kune rumwe rutivi, kumhanya kwakaderera; Kune rumwe rutivi, kana chikamu chikarambwa mutoro, kuitira kudzivirira kuputika kwepombi yesimbi kunokonzerwa nenyundo yemvura yakasimba, nguva yekuvharwa kwechimbichimbi yeguide vane inodiwa kuti ive yakareba, asi izvi zvichaita kuti kumhanya kwechikamu kuve kwakanyanya. Nokudaro, rotor inofanirwa kuva nehuremu hwakawanda uye inertia.
(4) Kushandiswa kwemagetsi akamira (vertical axis). Kuti kuderedza kugara kwevhu nemitengo yemiti, majenareta makuru nepakati anowanzo shandisa vertical shaft.
Majenareta emvura anogona kukamurwa kuita mhando dzakamira nedzakatambarara zvichienderana nekurongeka kwakasiyana kwemashafts avo anotenderera: majenareta emvura akamira anogona kukamurwa kuita mhando dzakasungirirwa nedzaamburera zvichienderana nenzvimbo dzakasiyana dzemabheya avo ekupinza.
(1) Hydrogenerator Yakasungirirwa. Chinopinza chinoiswa pakati kana pamusoro pefuremu yepamusoro yerotor, iyo inoshanda zvakatsiga uye inogadziriswa zviri nyore, asi kureba kwakakura uye mari inoshandiswa mufekitori yakakura.
(2) Jenareta yemvura yeAmburera. Bearing yesimbi inoiswa pakati pemuviri kana pamusoro pefuremu yepasi perotor. Kazhinji, majenareta makuru emvura ane kumhanya kwepakati nepasi anofanira kushandisa mhando yeamburera nekuda kwehukuru hwawo hwakakura, kuitira kuderedza kukwirira kweyuniti, kuchengetedza simbi uye kuderedza mari inoiswa mufekitori. Mumakore achangopfuura, chimiro chekuisa bearing yesimbi pamusoro pechifukidziro chemvura chakagadzirwa, uye kukwirira kweyuniti kunogona kuderedzwa.
2. Zvikamu zvikuru
Jenareta yemvura inonyanya kuumbwa ne stator, rotor, thrust bearing, mabheyaringi ekutungamira ekumusoro nepasi, mafuremu ekumusoro nepasi, mudziyo wekufema nekutonhodza, mudziyo wekubhureka uye mudziyo wekumutsa.
(1) Stator. Icho chinhu chinogadzira simba remagetsi, iro rinoumbwa nekumonereka, simbi negoko. Nekuti dhayamita yestator yemajenareta makuru nepakati yakakura kwazvo, inowanzo umbwa nezvikamu zvekutakura.
(2) Rotor. Ichikamu chinotenderera chinoburitsa simba remagineti, iro rinoumbwa nerutsigiro, mhete yevhiri nedanda remagineti. Mhete yevhiri idenderedzwa rakaita sedenderedzwa rakagadzirwa nesimbi yakaita sefeni. Matanda emagineti anoparadzirwa kunze kwemhete yevhiri, uye mhete yevhiri inoshandiswa senzira yesimba remagineti. Tambo imwe yerotor hombe nepakati inounganidzwa panzvimbo yacho, yozopiswa uye inoiswa maoko pashaft huru yejenareta. Mumakore achangopfuura, chimiro chisina shaft yerotor chakagadzirwa, kureva kuti, rutsigiro rwerotor rwakanamirwa zvakananga pamucheto wepamusoro weshaft huru yeturbine. Chinhu chikuru chechimiro ichi ndechekuti chinogona kugadzirisa matambudziko emhando yepamusoro emakasitoma makuru uye forgings anokonzerwa neyuniti hombe; Pamusoro pezvo, inogona zvakare kuderedza huremu hwekusimudza rotor uye kukwirira kwekusimudza, kuitira kuderedza kukwirira kwechirimwa uye kuunza hupfumi hwakati wandei pakuvaka kwechirimwa chemagetsi.
(3) Kubata kweThrust. Icho chikamu chinotakura huremu hwese hwechikamu chinotenderera cheyuniti uye kupinza kweaxial hydraulic kweturbine.
(4) Sisitimu yekutonhodza. Hydrogenerator inowanzo shandisa mhepo senzvimbo yekutonhodza kuti itonhodze stator, rotor winding uye stator core. Majenereta madiki ehydro anowanzo shandisa mhepo yakavhurika kana yepombi, nepo majenereta makuru neepakati anowanzo shandisa mhepo yakavharika yega. Kuti vawedzere kutonhora, mamwe ma hydro generator ane simba guru anoshandisa nzira yekutonhodza yemukati ye hollow conductor inopfuura zvakananga nepakati pemhepo inotonhodza, uye inotonhodza inoshandisa mvura kana nzira itsva. Ma stator ne rotor windings anotonhodzwa mukati nemvura, uye inotonhodza imvura kana nzira itsva. Ma stator ne rotor windings anotora mvura inotonhodza mukati anonzi double water internal cooling. Ma stator ne rotor windings uye stator core anotora mvura inotonhodza anonzi full water internal cooling, asi ma stator ne rotor windings anotora mvura inotonhodza mukati anonzi semi water internal cooling.
Imwe nzira yekutonhodza inoshandiswa ne hydro generator ndeye evaporative cooling, iyo inobatanidza liquid medium mu conductor ye hydro generator kuti itonhodze evaporative. Evaporative cooling ine zvakanakira zvekuti thermal conductivity ye thermal medium yakakura kupfuura yemhepo nemvura, uye inogona kuderedza huremu nehukuru hweyuniti.
(5) Mudziyo wekumutsa uye kugadzirwa kwawo zvakafanana nemidziyo yemagetsi ekupisa.
