Cov yam ntxwv ntawm Hydro Turbine Generator piv rau Steam Turbine Generator

Piv nrog lub tshuab hluav taws xob turbine, lub tshuab hluav taws xob hydro muaj cov yam ntxwv hauv qab no:
(1) Qhov ceev yog qis. Txwv los ntawm lub taub hau dej, qhov ceev tig feem ntau tsawg dua 750r / feeb, thiab qee qhov tsuas yog kaum ob ntawm kev hloov pauv ib feeb.
(2) Tus naj npawb ntawm cov ncej sib nqus loj heev. Vim tias qhov ceev qis, txhawm rau tsim kom muaj zog hluav taws xob 50Hz, nws yog qhov tsim nyog los nce tus naj npawb ntawm cov ncej sib nqus, yog li lub zog sib nqus ntawm kev txiav stator winding tseem tuaj yeem hloov pauv 50 zaug ib ob.
(3) Cov qauv loj thiab hnyav. Ntawm ib sab tes, qhov ceev qis; Ntawm qhov tod tes, yog tias lub tshuab tsis kam thauj khoom, kom tsis txhob muaj kev tawg ntawm cov yeeb nkab hlau los ntawm lub zog dej rauj, lub sijhawm kaw xwm txheej ceev ntawm lub vane qhia yuav tsum ntev, tab sis qhov no yuav ua rau qhov ceev ntawm lub tshuab nce siab dhau. Yog li ntawd, lub rotor yuav tsum muaj qhov hnyav loj thiab inertia.
(4) Feem ntau siv txoj kab ntsug. Yuav kom txo tau kev siv av thiab nqi cog qoob loo, cov tshuab hluav taws xob loj thiab nruab nrab feem ntau siv txoj kab ntsug.

Cov tshuab hluav taws xob hydro muaj peev xwm muab faib ua hom ntsug thiab kab rov tav raws li qhov sib txawv ntawm lawv cov ncej tig: cov tshuab hluav taws xob hydro ntsug muaj peev xwm muab faib ua hom dai thiab hom kaus raws li qhov sib txawv ntawm lawv cov bearings thrust.
(1) Lub tshuab Hydrogenerator uas raug tshem tawm. Lub thrust bearing tau teeb tsa rau hauv nruab nrab lossis sab saud ntawm lub thav duab sab saud ntawm lub rotor, uas muaj kev ua haujlwm ruaj khov thiab kev saib xyuas yooj yim, tab sis qhov siab loj thiab kev nqis peev ntawm cov nroj tsuag loj.
(2) Lub tshuab hluav taws xob Umbrella hydro generator. Lub thrust bearing tau teeb tsa rau hauv nruab nrab lub cev lossis nws sab saud ntawm lub thav duab qis ntawm lub rotor. Feem ntau, cov tshuab hluav taws xob hydro loj nrog qhov nruab nrab thiab qis ceev yuav tsum tau txais hom umbrella vim lawv qhov loj me, kom txo qhov siab ntawm lub tshuab, txuag hlau thiab txo cov peev txheej cog. Nyob rau hauv xyoo tas los no, cov qauv ntawm kev teeb tsa lub thrust bearing rau ntawm lub hau sab saum toj ntawm lub turbine dej tau tsim, thiab qhov siab ntawm lub tshuab tuaj yeem txo qis.

2. Cov Cheebtsam Tseem Ceeb
Hydro generator feem ntau yog tsim los ntawm stator, rotor, thrust bearing, upper thiab lower guide bearings, upper thiab lower frames, ventilation thiab cooling device, braking device thiab excitation device.
(1) Stator. Nws yog ib qho khoom siv rau kev tsim hluav taws xob, uas muaj cov xov hlau, hlau core thiab plhaub. Vim tias lub stator txoj kab uas hla ntawm cov tshuab hluav taws xob loj thiab nruab nrab loj heev, nws feem ntau yog tsim los ntawm cov ntu rau kev thauj mus los.
(2) Rotor. Nws yog ib feem uas tig los ua lub zog sib nqus, uas muaj cov khoom txhawb nqa, lub nplhaib log thiab lub ncej sib nqus. Lub nplhaib log yog ib qho khoom zoo li lub nplhaib uas muaj cov hlau zoo li lub kiv cua. Cov ncej sib nqus tau muab faib rau sab nraud lub nplhaib log, thiab lub nplhaib log siv ua txoj kev ntawm lub zog sib nqus. Ib txoj hlua ntawm lub rotor loj thiab nruab nrab tau sib sau ua ke ntawm qhov chaw, thiab tom qab ntawd cua sov thiab muab tso rau ntawm lub ncej tseem ceeb ntawm lub tshuab hluav taws xob. Nyob rau xyoo tas los no, cov qauv rotor tsis muaj ncej tau tsim, uas yog, kev txhawb nqa rotor tau ncaj qha rau ntawm qhov kawg ntawm lub ncej tseem ceeb ntawm lub turbine. Qhov zoo tshaj plaws ntawm cov qauv no yog tias nws tuaj yeem daws cov teeb meem zoo ntawm cov castings loj thiab forgings uas tshwm sim los ntawm lub tshuab loj; Tsis tas li ntawd, nws kuj tseem tuaj yeem txo qhov hnyav ntawm lub rotor thiab qhov siab ntawm kev nqa, yog li txo qhov siab ntawm lub tshuab thiab coj qee yam kev lag luam rau kev tsim kho lub zog fais fab.
(3) Lub zog thawb. Nws yog ib qho khoom uas dais tag nrho qhov hnyav ntawm qhov tig ntawm lub tshuab thiab lub zog hydraulic axial ntawm lub turbine.
(4) Lub tshuab cua txias. Hydrogenerator feem ntau siv cua ua cua txias kom txias lub stator, rotor winding thiab stator core. Cov tshuab hluav taws xob me me feem ntau siv qhov cua qhib lossis yeeb nkab, thaum cov tshuab hluav taws xob loj thiab nruab nrab feem ntau siv qhov cua kaw. Txhawm rau txhim kho qhov txias, qee lub tshuab hluav taws xob hydro generator muaj peev xwm siab siv hom cua txias sab hauv ntawm cov neeg hlau hollow ncaj qha hla dhau qhov cua txias, thiab qhov cua txias siv dej lossis tshiab. Cov stator thiab rotor windings raug txias sab hauv los ntawm dej, thiab qhov cua txias yog dej lossis tshiab. Cov stator thiab rotor windings uas siv dej txias sab hauv hu ua ob chav dej txias sab hauv. Cov stator thiab rotor windings thiab stator core uas siv dej txias hu ua dej puv sab hauv txias, tab sis cov stator thiab rotor windings uas siv dej txias sab hauv hu ua semi dej txias sab hauv.
Lwm txoj kev txias ntawm lub tshuab hluav taws xob hydro yog evaporative cooling, uas txuas cov kua nruab nrab rau hauv tus neeg xyuas pib ntawm lub tshuab hluav taws xob hydro rau kev txias evaporative. Evaporative cooling muaj qhov zoo uas qhov thermal conductivity ntawm qhov txias nruab nrab yog ntau dua li ntawm huab cua thiab dej, thiab tuaj yeem txo qhov hnyav thiab qhov loj ntawm lub tshuab.
(5) Lub cuab yeej txhawb nqa thiab nws txoj kev loj hlob zoo ib yam li cov ntawm cov chaw ua haujlwm thermal fais fab.
