South African Cov Neeg Siv Khoom Txhim Kho ntawm 200kW Kaplan Hydropower Plant Ua tiav Los ntawm Forster

Tsis ntev los no, Forster tau ua tiav tau pab South Africa cov neeg siv khoom txhim kho lub zog ntawm nws qhov chaw nres tsheb 100kW hydropower rau 200kW.Txoj kev hloov kho tshiab yog raws li hauv qab no
200KW kaplan turbine generator
Rated taub hau 8.15 m
Tsim kev khiav 3.6m3/s
Tshaj siab tshaj 8.0m3 / s
Yam tsawg kawg nkaus 3.0m3/s
Rated ntsia muaj peev xwm 200kW
Cov neeg siv khoom tau pib txhim kho qhov chaw nres tsheb dej hauv lub Kaum Ob Hlis xyoo tas los.Forster hloov lub turbine thiab lub tshuab hluav taws xob rau cov neeg siv khoom thiab txhim kho kev tswj hwm.Tom qab nce lub taub hau dej los ntawm 1m, lub zog hluav taws xob tau hloov kho los ntawm 100kW mus rau 200kW, thiab cov kab sib txuas txuas ntxiv tau ntxiv.Tam sim no, nws tau ua tiav kev sib txuas ntawm kab sib chaws rau kev tsim hluav taws xob, thiab cov neeg siv khoom zoo siab heev

Qhov zoo ntawm Forster axial turbine
1. High precision ceev thiab zoo zog yam ntxwv.Yog li ntawd, nws chav tsev ceev thiab chav dej ntws yog siab dua li ntawm Francis turbine.Nyob rau hauv tib lub taub hau thiab cov khoom tso tawm, nws tuaj yeem txo qhov loj ntawm hydraulic turbine generator unit, txo qhov hnyav ntawm chav tsev thiab txuag cov khoom siv, yog li nws muaj txiaj ntsig zoo rau kev lag luam.
2. Cov duab thiab qhov roughness ntawm cov hniav ntawm cov axial-flow turbine yog ib qho yooj yim kom ua tau raws li qhov yuav tsum tau ua hauv kev tsim khoom.Vim hais tias cov hniav ntawm axial flow propeller turbine tuaj yeem tig, qhov nruab nrab efficiency siab dua li ntawm Francis turbine.Thaum lub load thiab lub taub hau hloov, efficiency hloov me ntsis.
3. Cov hniav khiav ntawm axial flow paddle turbine tuaj yeem raug tshem tawm kom yooj yim rau kev tsim khoom thiab kev thauj mus los.
Yog li ntawd, axial-flow turbine ua kom ruaj khov nyob rau hauv kev ua haujlwm loj, muaj kev vibration tsawg, thiab muaj kev ua haujlwm siab thiab tso tawm.Nyob rau hauv qhov ntau ntawm cov dej qis taub hau, nws yuav luag hloov Francis turbine.Nyob rau hauv xyoo tsis ntev los no, nws tau ua rau kev loj hlob zoo thiab dav siv nyob rau hauv cov nqe lus ntawm ib chav tsev muaj peev xwm thiab lub taub hau dej.

Qhov tsis zoo ntawm Forster axial turbine
1. Tus naj npawb ntawm cov hniav yog me me thiab cantilever, yog li lub zog tsis zoo thiab tsis tuaj yeem siv rau nruab nrab thiab siab lub taub hau hydropower chaw nres tsheb.
2. Vim yog chav tsev loj ntws thiab siab ceev, nws muaj qhov nqus me me qhov siab tshaj Francis turbine nyob rau hauv tib lub taub hau dej, uas ua rau qhov loj excavation qhov tob thiab kuj siab peev ntawm lub hwj chim chaw nres tsheb foundation.

Raws li cov kev tsis txaus siab saum toj no ntawm axial-flow turbine, daim ntawv thov lub taub hau ntawm axial-flow turbine txuas ntxiv txhim kho los ntawm kev siv cov ntaub ntawv tshiab nrog lub zog siab thiab cavitation tsis kam nyob rau hauv turbine manufacturing thiab txhim kho cov kev ntxhov siab ntawm cov hniav hauv kev tsim.Tam sim no, daim ntawv thov lub taub hau ntau ntawm axial flow kiv cua turbine yog 3-90 m, uas tau nkag mus rau thaj tsam ntawm Francis turbine.
