Turbine yog hais txog lub tshuab hluav taws xob xa hluav taws xob uas hloov cov thermal nyhuv ntawm cov dej ntws mus rau hauv kev sib hloov txhua yam kinetic zog. Qhov tseem ceeb yog siv nyob rau hauv hydropower nroj tsuag los tsav cua turbines los tsim electromagnetic zog, uas yog ib qho tseem ceeb electromechanical khoom rau hydropower nroj tsuag. Raws li nws txoj cai, nws tuaj yeem muab faib ua ob hom: cuam tshuam turbine thiab cuam tshuam turbine. Cia peb saib seb dab tsi yog hydro turbine? Tus qauv ntawm hydro turbine yog dab tsi?
Dab tsi yog qhov dej turbine?
Lub turbine dej yog hloov zuj zus los ntawm lub log dej los yog lub tsheb smuggling nyob rau hauv ancient sij hawm. Nyob rau hauv 1827, Fabkis technical engineer B. Fourneron ua 6-horsepower impact turbine. Xyoo 1849, nws tau txhim kho los ntawm kev tsim qauv ntawm American technical engineer JB Francis los tsim ib lub caij nyoog Francis turbine, yog li nws hu ua Francis turbine. Qhov cuam tshuam turbine tshwm sim hauv 1850. Los ntawm 1880, American technical engineer LA Pelton tau txais txoj cai patent ntawm lub thoob-hom impingement turbine, uas yog hu ua Pelton turbine. Nrog rau kev nce qib ntawm kev txhim kho thiab tsim cov phiaj xwm hydropower, hom, yam ntxwv thiab cov qauv ntawm hydraulic turbines tau dhau los ua ntau thiab zoo meej. Xyoo 1912, Austrian technical engineer V. Kaplan tau tsim thawj lub kiv cua axial kiv cua turbine, thiaj li hu ua Kaplan turbine. Hauv xyoo 1940 thiab 1950s, axial-flow thiab oblique-flow turbines tshwm sim ib zaug. Nyob rau tib lub sijhawm, txoj kev loj hlob ntawm hydraulic turbines yog centrifugal twj turbines, uas tau siv nyob rau hauv cov twj tso kua mis-cia fais fab nroj tsuag. Cov hom turbines tuaj yeem ua ke rau hauv cov hom phiaj sib txawv thiab cov kev cai ntawm cov taub dej sib txawv hauv kev tsim kho thiab tsim cov phiaj xwm dej. Tom qab nrhiav tau ntawm cov neeg koom pheej ntawm Tuam Tshoj, kev lag luam ntawm Tuam Tshoj lub turbine ntau lawm thiab kev tsim khoom tau ua tiav sai. Muaj ntau tshaj li 20 lub tshuab tsim hluav taws xob, uas tau tsim ntau tshaj 20 lab kW ntawm turbine riam phom thiab khoom siv rau cov nroj tsuag dej thoob plaws lub tebchaws, thiab xa tawm mus rau txawv teb chaws.
Raws li cov yam ntxwv ntawm kev hloov pauv cua sov, hydro turbines tau muab faib ua ob pawg, uas yog hom kev tawm tsam thiab kev cuam tshuam. Thiab txhua hom turbine tau muab faib ua ntau hom ntawv raws li cov yam ntxwv ntawm cov dej ntws hauv thaj chaw tig ncej thiab cov qauv qauv ntawm lub rotating ncej.
Tus qauv ntawm lub turbine yog dab tsi?
Hydraulic turbine yog hydraulic turbine ntawm lub zog hluav taws xob tsim hluav taws xob tshuab hluav taws xob. Hydraulic turbine thiab cua turbine, ceev tswj lub cev muaj zog, excitation regulator system thiab lub hwj chim chaw nres tsheb tswj system yog siv nyob rau hauv cov kev txhawb pab, uas yog lub ntsiab lub cev ntawm lub chaw nres tsheb hydropower.
Cov dej turbine yog tsim thiab tsim raws li cov ntaub ntawv ntws thiab lub taub hau loj ntawm cov dej. Nws txoj haujlwm yog hloov dej mus rau hauv lub zog txhua yam thiab txhawb nqa lub zog tsim hluav taws xob ntawm cua turbines. Lub turbine nws tus kheej muaj cov turbine ncej, lub turbine lub nplhaib, lub turbine volute thiab turbine lub ntsiab ncej bearing. Tsis tas li ntawd, nyob ntawm qhov kev qhia tshwj xeeb, cov khoom siv ntxiv thiab cov khoom siv kuj tseem raug teeb tsa. Ntau hom turbines muaj cov qauv sib txawv thiab kev siv.
