Kukonzanso kwa Kasitomala wa Kaplan Hydropower wa 200kW ku South Africa Kwamalizidwa ndi Forster

Posachedwapa, Forster wathandiza makasitomala aku South Africa kukweza mphamvu ya siteshoni yake yamagetsi ya 100kW kufika pa 200kW. Ndondomeko yokweza ndi iyi:
Jenereta ya turbine ya kaplan ya 200KW
Mutu woyesedwa 8.15 m
Kapangidwe kake 3.6m3/s
Kuthamanga kwakukulu 8.0m3/s
Kuthamanga kochepa 3.0m3/s
Mphamvu yoyikidwa ndi 200kW
Kasitomala anayamba kukweza siteshoni yamagetsi yamadzi mu Disembala chaka chatha. Forster adasintha turbine ndi jenereta ya kasitomala ndikukweza makina owongolera. Atawonjezera mutu wamadzi ndi 1m, mphamvu yoyikidwayo idakwezedwa kuchokera pa 100kW kufika pa 200kW, ndipo makina olumikizira gridi adawonjezedwa. Pakadali pano, yalumikizidwa bwino ku gridi kuti ipange magetsi, ndipo makasitomala ali okondwa kwambiri.

Ubwino wa turbine ya axial ya Forster
1. Liwiro lapadera komanso mphamvu zabwino. Chifukwa chake, liwiro la unit yake ndi kuyenda kwa unit ndi zokwera kuposa za Francis turbine. Pansi pa mikhalidwe yomweyi ya mutu ndi kutulutsa, imatha kuchepetsa kwambiri kukula kwa unit ya hydraulic turbine, kuchepetsa kulemera kwa unit ndikusunga kugwiritsa ntchito zinthu, kotero imakhala ndi phindu lalikulu pazachuma.
2. Kapangidwe ka pamwamba ndi kuuma kwa pamwamba kwa masamba othamanga a turbine ya axial-flow n'kosavuta kukwaniritsa zofunikira popanga. Chifukwa masamba a turbine ya axial flow propeller amatha kuzungulira, magwiridwe antchito apakati amakhala apamwamba kuposa a turbine ya Francis. Pamene katundu ndi mutu zisintha, magwiridwe antchito sasintha kwenikweni.
3. Masamba othamanga a turbine ya axial flow paddle amatha kuchotsedwa kuti apange mosavuta komanso kuti azitha kunyamula.
Chifukwa chake, turbine ya axial-flow imakhala yokhazikika pamlingo waukulu wogwirira ntchito, imakhala ndi kugwedezeka kochepa, komanso imagwira ntchito bwino komanso kutulutsa mphamvu. Pamtundu wa mutu wamadzi wotsika, imalowa m'malo mwa turbine ya Francis. M'zaka zaposachedwa, yapanga chitukuko chachikulu komanso kugwiritsidwa ntchito kwambiri pankhani ya mphamvu ya unit imodzi komanso mutu wamadzi.

Zoyipa za Forster axial turbine
1. Chiwerengero cha masamba ndi chaching'ono komanso cholimba, kotero mphamvu yake ndi yochepa ndipo singagwiritsidwe ntchito pa malo opangira magetsi apakati ndi apamwamba.
2. Chifukwa cha kuyenda kwa unit yayikulu komanso liwiro lalikulu la unit, ili ndi kutalika kochepa koyamwa kuposa Francis turbine pansi pa mutu womwewo wa madzi, zomwe zimapangitsa kuti kufukula kukhale kwakukulu komanso kuyika ndalama zambiri pa maziko a siteshoni yamagetsi.

Malinga ndi zofooka zomwe zili pamwambapa za turbine ya axial-flow, mutu wogwiritsira ntchito wa turbine ya axial-flow umasinthidwa nthawi zonse mwa kugwiritsa ntchito zipangizo zatsopano zomwe zimakhala ndi mphamvu zambiri komanso kukana kutsekeka kwa cavitation popanga turbine ndikukweza mkhalidwe wa kupsinjika kwa masamba omwe akupangidwa. Pakadali pano, mutu wogwiritsira ntchito wa turbine ya axial flow propeller ndi 3-90 m, womwe walowa m'dera la turbine ya Francis.
