Muva nje, uForster usize amakhasimende aseNingizimu Afrika ngempumelelo ukuthuthukisa amandla afakiwe esiteshini sakhe sikagesi samanzi esingu-100kW abe ngu-200kW. Uhlelo lokuthuthukisa lumi kanje:
Ijeneretha ye-turbine ye-kaplan engu-200KW
Ikhanda elilinganiselwe 8.15 m
Ukugeleza komklamo 3.6m3/s
Ukugeleza okuphezulu kakhulu 8.0m3/s
Ukugeleza okuncane kakhulu 3.0m3/s
Umthamo ofakiwe ulinganiselwe ku-200kW
Ikhasimende laqala ukuthuthukisa isiteshi sikagesi samanzi ngoDisemba ngonyaka odlule. I-Forster yashintsha i-turbine kanye nejenereyitha yekhasimende futhi yathuthukisa uhlelo lokulawula. Ngemva kokwandisa ikhanda lamanzi ngo-1m, amandla afakiwe athuthukiswa kusuka ku-100kW kuya ku-200kW, futhi uhlelo lokuxhuma igridi lwengezwa. Njengamanje, luxhunywe ngempumelelo kugridi ukuze kukhiqizwe ugesi, futhi amakhasimende ajabule kakhulu.
Izinzuzo ze-Forster axial turbine
1. Isivinini esiphezulu kanye nezici ezinhle zamandla. Ngakho-ke, isivinini sayo seyunithi kanye nokugeleza kweyunithi kuphakeme kunese-Francis turbine. Ngaphansi kwezimo ezifanayo zekhanda kanye nokukhipha, inganciphisa kakhulu usayizi weyunithi yejeneretha ye-hydraulic turbine, inciphise isisindo seyunithi futhi yonge ukusetshenziswa kwezinto, ngakho-ke inezinzuzo eziphezulu zomnotho.
2. Ukuma kobuso kanye nobukhali bobuso bama-runner blades e-axial-flow turbine kulula ukuhlangabezana nezidingo ekukhiqizeni. Ngenxa yokuthi ama-blades e-axial flow propeller turbine angajikeleza, ukusebenza kahle okumaphakathi kuphakeme kunokwe-Francis turbine. Lapho umthwalo nekhanda kushintsha, ukusebenza kahle akushintshanga kangako.
3. Ama-runner blades e-axial flow paddle turbine angahlakazwa ukuze kube lula ukukhiqiza nokuthuthwa.
Ngakho-ke, i-axial-flow turbine ihlala izinzile ebangeni elikhulu lokusebenza, inokudlidliza okuncane, futhi isebenza kahle kakhulu futhi ikhipha kahle. Ebangeni lekhanda lamanzi aphansi, cishe ithatha indawo ye-Francis turbine. Emashumini eminyaka amuva nje, iye yaba nentuthuko enkulu kanye nokusetshenziswa okubanzi maqondana nomthamo weyunithi eyodwa kanye nekhanda lamanzi.
Izinkinga ze-Forster axial turbine
1. Inani lama-blade lincane futhi alinawo ugesi, ngakho-ke amandla aphansi futhi awakwazi ukusetshenziswa eziteshini zamandla kagesi ezisezingeni eliphakathi neliphezulu.
2. Ngenxa yokugeleza okukhulu kweyunithi kanye nesivinini esikhulu seyunithi, inokuphakama okuncane kokumunca kune-Francis turbine ngaphansi kwekhanda lamanzi elifanayo, okuholela ekujuleni okukhulu kokumba kanye nokutshalwa kwezimali okuphezulu kwesisekelo sesiteshi samandla.
Ngokusho kokushiyeka okungenhla kwe-axial-flow turbine, ikhanda lokusebenza le-axial-flow turbine lithuthukiswa njalo ngokusebenzisa izinto ezintsha ezinamandla aphezulu kanye nokumelana ne-cavitation ekukhiqizweni kwe-turbine kanye nokuthuthukisa isimo sokucindezeleka kwama-blades ekuklanyweni. Njengamanje, ububanzi bekhanda lokusebenza le-axial flow propeller turbine bungama-3-90 m, okungene endaweni ye-Francis turbine.
