Tubular turbines: Tus yuam sij rau kev qhib lub neej yav tom ntej ntawm cov dej fais fab qis

Cov dej uas ib zaug tsis muaj zog ntws ntawm thaj av tiaj thiab hav dej tam sim no raug hloov mus ua hluav taws xob huv los ntawm cov turbines tubular.
Ntawm cov khoom siv hydropower, tubular turbines, ua lub hauv paus rau kev tsim cov peev txheej hydropower qis-head, tab tom qhia txog kev siv dav dua. kuv lub tebchaws muaj cov peev txheej hydropower qis-head loj heev uas tsim nyog rau kev tsim tubular turbine. Cov peev txheej nrog lub taub hau kwv yees li 10 meters kwv yees tias yuav tsim tau ntau dua 20 gigawatts. Ua ke nrog ntau dua 21 gigawatts ntawm lub zog tidal siv tau, qhov no muab kev lag luam loj rau tubular turbines.
01 Cov Kev Zoo ntawm Kev Siv Tshuab: Kev daws teeb meem zoo rau lub zog dej qis qis
Ua ib chav tsev uas teeb tsa kab rov tav nrog cov dej ntws sib luag rau lub axis tseem ceeb, cov turbines tubular ua rau pom kev ua tau zoo dua nyob rau hauv cov xwm txheej qis.
Piv rau cov chav ntsug, cov turbine tubular muaj kev hloov pauv hluav taws xob zoo dua. Hom turbine no tau teeb tsa kab rov tav, nrog rau qhov tob tob uas tsis tob, ua rau muaj tsawg dua kev ua haujlwm engineering thiab txo qis kev nqis peev hauv kev tsim kho vaj tse.
Tsis tas li ntawd xwb, lub turbine tubular yog ib lub tshuab uas tswj tau ob txoj kev. Nws lub zog tsim hluav taws xob raug tswj los ntawm cov vanes uas kho qhov nrawm ntawm dej ntws, thiab los ntawm cov hniav propeller, uas kho qhov ua haujlwm ntawm lub turbine, yog li ua kom ntseeg tau tias kev ua haujlwm nyob rau hauv qhov ua haujlwm tau zoo tshaj plaws.
Hauv qhov siab li ntawm 3-20 meters, cov turbines tubular ua haujlwm tau zoo heev, tsim cov peev txheej qis uas yav dhau los nyuaj rau siv. Tshwj xeeb, cov turbines tubular tau dhau los ua qhov kev xaiv zoo tshaj plaws rau kev tsim hydropower hauv qab 25 meters.
02 Lub Zeem Muag Daim Ntawv Thov: Los ntawm Cov Dej Mus Rau Dej Hiav Txwv
Raws li cov peev txheej hydropower nruab nrab thiab siab zuj zus ploj mus, kev txhim kho cov peev txheej qis dua kuj tseem ceeb zuj zus, thiab cov turbines tubular muaj peev xwm zoo heev hauv thaj chaw no.
kuv lub teb chaws muaj ntau yam khoom siv hluav taws xob tsawg, feem ntau nyob hauv thaj chaw uas muaj kev lag luam zoo thiab muaj neeg nyob coob lossis hav dej. Hauv cov cheeb tsam no, cov turbines tubular tuaj yeem ua tiav cov haujlwm siv dav dav xws li kev tsim hluav taws xob, kev tswj dej nyab, thiab kev xa khoom, thaum tseem pab txhawb kev tiv thaiv ib puag ncig thiab cov peev txheej av.
Qhov tseem ceeb, cov turbines tubular muaj kev siv dav hauv kev tsim hluav taws xob hauv dej hiav txwv. Cov twj tso kua mis tubular-turbines uas tsim nyog rau cov chaw tsim hluav taws xob hauv dej hiav txwv tsis yog tsuas yog xav tau los muab kev tsim hluav taws xob ib txoj kev thiab kev twj tso kua mis xwb, tab sis qee zaum kuj tseem muab kev tsim hluav taws xob ob txoj kev, twj tso kua mis, thiab tso tawm.
Nrog kev nce qib ntawm lub hom phiaj "ob chav carbon", tiam tshiab ntawm cov tubular turbines, los ntawm kev tsim kho tshiab xws li CFD optimization thiab kev tswj hwm ntse, xav tias yuav ua tiav kev txhim kho kev ua haujlwm ntau dua 2% thiab lub neej ntev dua 30%.
03 Kev Txhim Kho Kev Siv Tshuab: Los Ntawm Kev Ntxeev Siab Mus Rau Kev Ua Tus Thawj Coj
Kuv lub teb chaws tau ua tiav kev vam meej tseem ceeb hauv kev siv tshuab tubular turbine. Txhawm rau daws cov teeb meem tseem ceeb xws li kev ua haujlwm tsis zoo, kev puas tsuaj loj heev, thiab kev sib txuas loj, cov pab pawg tshawb fawb Suav, los ntawm yuav luag 30 xyoo ntawm kev tshawb fawb sib koom tes ntawm kev lag luam, kev kawm, thiab kev tshawb fawb, tau tsim kho tshiab txoj kev tsim qauv ntawm cov khoom siv turbine thiab tsim kom muaj lub kaw lus tiv thaiv kev puas tsuaj rau axial-flow thiab tubular turbines.
Cov kev tshawb pom tshiab tshwj xeeb suav nrog: kev tsim cov qauv tsim peb-seem uas muaj kev sib hloov tig, ua tiav kev tsim cov qauv tsim ntawm cov kav dej khiav thiab cov kav dej; kev tsim cov txheej txheem los txheeb xyuas qhov pib ntawm cavitation hauv cov turbines; thiab kev tsim cov txheej txheem thev naus laus zis rau kev tiv thaiv kev yaig ntawm cov turbines hom propeller.
Cov kev ua tiav ntawm thev naus laus zis no tau txo qhov kev hloov kho dua tshiab rau cov chaw tsim hluav taws xob uas muaj cov dej ntws ntau los ntawm 2-3 xyoos mus rau kwv yees li 5 xyoos, ua rau kev siv nyiaj txiag ntawm cov chaw ua haujlwm zoo dua.
Qhov ua tau zoo tshaj plaws ntawm ntau lub qauv hydraulic ntawm tubular turbines tsim nyob rau hauv kuv lub teb chaws tau tshaj 94%. Lub Taocha tubular turbine qauv ua tiav qhov ua tau zoo ntawm 94.25%, qhov siab tshaj plaws hauv ntiaj teb, ua tiav kev hloov pauv ntawm kev xa tawm thev naus laus zis mus rau kev xa tawm thev naus laus zis.
