Axial-flow hydropower nroj tsuag, feem ntau nruab nrog Kaplan turbines, yog qhov zoo tagnrho rau cov chaw uas muaj lub taub hau qis mus rau nruab nrab thiab cov dej ntws loj. Cov turbines no tau siv dav hauv kev khiav dej num thiab lub taub hau qis vim lawv cov kev ua haujlwm siab thiab kev hloov pauv. Kev vam meej ntawm cov kev tsim hluav taws xob zoo li no yog nyob ntawm kev tsim kom zoo thiab ua tib zoo ua haujlwm rau pej xeem, uas tsim lub hauv paus rau kev ua haujlwm ntawm lub tshuab hluav taws xob, kev ua haujlwm ruaj khov, thiab kev nyab xeeb.
1. Kev Npaj Qhov Chaw thiab Kev Hloov Dej
Ua ntej txhua qhov kev tsim kho loj pib, kev npaj qhov chaw yog qhov tseem ceeb. Qhov no suav nrog kev tshem thaj chaw tsim kho, teeb tsa txoj kev nkag mus, thiab tsim kom muaj kev hloov pauv dej ntws los hloov dej thiab tsim kom muaj chaw ua haujlwm qhuav. Cofferdams-cov ntaub thaiv ib ntus uas ua rau hauv lossis hla tus dej-feem ntau yog siv los cais qhov chaw tsim kho los ntawm dej.
2. Cov qauv nkag
Cov qauv kev noj haus tswj cov dej nkag mus rau hauv lub tshuab fais fab thiab xyuas kom tsis muaj khib nyiab, ruaj khov ntws mus rau lub turbine. Nws suav nrog cov khib nyiab khib nyiab, cov rooj vag, thiab qee zaum cov dej ntws tawm. Kev tsim hydraulic tsim nyog yog qhov tseem ceeb los tiv thaiv kev tsim vortex, txo qis taub hau poob, thiab tiv thaiv lub turbine los ntawm cov khib nyiab ntab.
3. Penstock lossis Qhib Channel
Nyob ntawm qhov kev teeb tsa, cov dej los ntawm qhov nqus tau xa mus rau lub turbine ntawm penstocks (kaw kav) los yog qhib raws. Nyob rau hauv ntau axial-flow designs - tshwj xeeb tshaj yog nyob rau hauv qis-head nroj tsuag - ib tug qhib kom tsawg txuas ncaj qha mus rau lub turbine yog siv. Cov qauv kev ruaj ntseg, ntws sib xws, thiab txo qis ntawm hydraulic poob yog qhov kev txhawj xeeb tseem ceeb nyob rau theem no.
4. Powerhouse Structure
Lub hwj chim tsev muaj lub tshuab hluav taws xob turbine, tswj cov tshuab, thiab cov cuab yeej pabcuam. Rau Kaplan turbines, uas feem ntau yog ntsia vertically, lub hwj chim yuav tsum tau tsim los txhawb nqa loj axial loads thiab dynamic rog. Vibrational stability, waterproofing, thiab yooj yim rau kev saib xyuas yog qhov tseem ceeb ntawm cov qauv tsim.
5. Draft Tube thiab Tailrace
Cov cua ntsawj ntshab ua lub luag haujlwm tseem ceeb hauv kev rov ua kom lub zog kinetic los ntawm cov dej tawm ntawm lub turbine. Ib tug zoo-tsim cua ntsawj ntshab tube nce efficiency tag nrho. Lub tailrace channel conveys dej nyab xeeb rov qab mus rau tus dej. Ob qho tib si cov qauv yuav tsum tau ua kom meej meej kom txo tau turbulence thiab backwater cuam tshuam.
6. Tswj Chav thiab Lub Tsev Pabcuam
Sib nrug los ntawm cov qauv tseem ceeb, kev ua haujlwm hauv pej xeem kuj suav nrog kev tsim cov chav tswj, cov neeg ua haujlwm hauv tsev, cov chaw ua haujlwm, thiab lwm lub tsev ua haujlwm. Cov chaw no ua kom ntseeg tau cov nroj tsuag kev ua haujlwm thiab kev saib xyuas mus ntev.
7. Kev xav txog ib puag ncig thiab Geotechnical
Kev tshawb nrhiav av, stabilization ntawm txoj kab nqes, tswj kev yaig, thiab kev tiv thaiv ib puag ncig yog qhov tseem ceeb ntawm kev npaj pej xeem. Cov kab dej kom zoo, cov kab ntses (qhov twg yuav tsum tau ua), thiab kev tsim kho kom zoo nkauj yuav pab txo qhov kev cuam tshuam ib puag ncig ntawm qhov project.
Lub hauv paus ntawm kev tsim vaj tsev engineering ntawm axial-flow hydropower cog yog qhov tseem ceeb rau nws qhov kev ua tau zoo thiab kev ua haujlwm ntev. Txhua tus qauv - los ntawm kev nkag mus rau lub tailrace - yuav tsum tau ua tib zoo tsim thiab tsim kom muaj zog tiv thaiv dej, geological tej yam kev mob, thiab kev xav tau kev ua haujlwm. Kev sib raug zoo ntawm cov engineers pej xeem, cov khoom siv hluav taws xob siv hluav taws xob, thiab cov kws paub txog ib puag ncig yog qhov tseem ceeb rau kev xa cov tshuaj muaj kev nyab xeeb, muaj txiaj ntsig, thiab muaj txiaj ntsig zoo.
