Kukwezera Makasitomala ku South Africa kwa 200kW Kaplan Hydropower Plant Kumalizidwa Ndi Forster

Posachedwapa, Forster anathandiza bwino makasitomala a ku South Africa kukweza mphamvu ya 100kW hydropower yake kukhala 200kW.Ndondomeko yowonjezera ili motere
200KW kaplan turbine jenereta
Mutu woyezedwa 8.15 m
Kuthamanga kwapangidwe 3.6m3 / s
Kuthamanga kwakukulu 8.0m3 / s
Kuthamanga kochepa 3.0m3 / s
Adavoteledwa mphamvu 200kW
Makasitomala adayamba kukweza malo opangira magetsi amadzi mu Disembala chaka chatha.Forster adalowa m'malo mwa turbine ndi jenereta kwa kasitomala ndikukweza makina owongolera.Pambuyo powonjezera mutu wamadzi ndi 1m, mphamvu yoyikidwa idakwezedwa kuchokera ku 100kW kupita ku 200kW, ndipo njira yolumikizira gululi idawonjezedwa.Pakalipano, idalumikizidwa bwino ndi gridi yopangira magetsi, ndipo makasitomala ali okondwa kwambiri

Ubwino wa Forster axial turbine
1. Kuthamanga kwakukulu kwapadera ndi makhalidwe abwino a mphamvu.Chifukwa chake, liwiro lake lagawo ndikuyenda kwagawo ndizokwera kuposa za Francis turbine.Pansi pamutu womwewo ndi zinthu zomwe zimatulutsa, zimatha kuchepetsa kwambiri kukula kwa hydraulic turbine generator unit, kuchepetsa kulemera kwa unit ndikusunga zinthu zakuthupi, kotero zimakhala ndi phindu lalikulu lazachuma.
2. Mawonekedwe a pamwamba ndi roughness pamwamba pa masamba othamanga a axial-flow turbine ndizosavuta kukwaniritsa zofunikira pakupanga.Chifukwa ma turbine a axial flow propeller turbine amatha kusinthasintha, kuchuluka kwake kumakhala kokwanira kuposa kwa Francis turbine.Pamene katundu ndi mutu zikusintha, dzuwa limasintha pang'ono.
3. Masamba othamanga a axial flow paddle turbine amatha kupasuka kuti athandizire kupanga ndi kuyendetsa.
Chifukwa chake, turbine ya axial-flow turbine imakhala yokhazikika pamagawo akulu opangira, imakhala ndi kugwedezeka pang'ono, ndipo imakhala yogwira ntchito kwambiri komanso yotulutsa.Pakati pamutu wamadzi otsika, pafupifupi m'malo mwa turbine ya Francis.M'zaka makumi angapo zapitazi, yapanga chitukuko chachikulu komanso kugwiritsa ntchito kwambiri potengera mphamvu ya unit imodzi ndi mutu wamadzi.

Zoyipa za Forster axial turbine
1. Chiwerengero cha masamba ndi ang'onoang'ono ndi cantilever, kotero mphamvu ndi osauka ndipo sangathe kugwiritsidwa ntchito kwa sing'anga ndi mkulu mutu hydropower stations.
2. Chifukwa cha kuchuluka kwa ma unit ndi liwiro lalikulu la unit, ili ndi kutalika kocheperako kuposa turbine ya Francis pansi pamutu womwewo wamadzi, zomwe zimapangitsa kuzama kwakukulu kofukula komanso ndalama zambiri zamakina opangira magetsi.

Malinga ndi zolakwika zomwe zili pamwambapa za turbine ya axial-flow turbine, mutu wa turbine wa axial-flow turbine umasinthidwa mosalekeza potengera zida zatsopano zokhala ndi mphamvu zambiri komanso kukana kwa cavitation popanga ma turbine ndikuwongolera kupsinjika kwa masamba pamapangidwe.Pakalipano, mutu wa ntchito wamtundu wa axial flow propeller turbine ndi 3-90 m, womwe walowa m'dera la Francis turbine.
