Kune akawanda marudzi emagetsi emagetsi emagetsi.Nhasi, ini ndichasuma iyo axial inoyerera hydroelectric jenareta zvakadzama.Iko kushandiswa kweaxial kuyerera turbine jenareta mumakore achangopfuura ndiko kunonyanya kuvandudzwa kwemusoro wepamusoro uye hukuru hukuru.Domestic axial-flow turbines ari kukura nekukurumidza.Iwo maviri axial-flow paddle-type turbines akaiswa paGezhouba Hydropower Station akavakwa.Imwe yacho ine dhayamita 11.3 metres, inova ndiyo yakakura kwazvo yerudzi rwayo munyika..Heano mabhenefiti uye kuipa kweaxial flow turbines.
Zvakanakira axial kuyerera turbine
Kuenzaniswa neFrancis turbines, axial flow turbines ane zvinotevera zvakakosha zvakanaka:
1. High chaiyo kumhanya uye kunaka simba hunhu.Naizvozvo, kumhanya kwayo kweyuniti uye kuyerera kweyuniti kwakakwira kupfuura iyo yeFrancis turbine.Pasi pemusoro wakafanana wemvura uye mamiriro ekubuda, inogona kuderedza zvakanyanya saizi yeturbine jenareta unit, kuderedza huremu hweyuniti, uye kuchengetedza kushandiswa kwezvinhu, saka zvine hupfumi.high.
2. Chimiro chepamusoro uye hutsinye hwepamusoro hwemumhanyi blade yeaxial flow turbine inogona kusangana nyore nyore nezvinodiwa mukugadzira.Nekuda kwekuti mablades eiyo axial-flow rotary-paddle turbine anogona kutenderera, avhareji yekushanda yakakwira kupfuura yeiyo yakasanganiswa-inoyerera turbine.Kana mutoro uye musoro wemvura uchichinja, kushanda zvakanaka hakuchinji zvakanyanya.
3. Mashizha anomhanya e-axial-flow paddle turbine anogona kuparadzaniswa, izvo zviri nyore pakugadzira uye kutakura.
Naizvozvo, iyo axial inoyerera turbine inogona kuchengetedza kugadzikana mune yakakura yekushanda renji, ine kushoma vibration, uye yakanyanya kunaka uye kubuda.Muchikamu chepamusoro-soro, inenge yakatsiva Francis turbine.Mumakumi emakore achangopfuura, zvese maererano neiyo imwechete unit kugona uye kushandiswa kwemusoro wemvura, kwave nekukura kukuru, uye kushandiswa kwayo kwakakurawo zvakanyanya.
Kuipa kweaxial flow turbine
Nekudaro, iyo axial kuyerera turbine inewo zvikanganiso uye inomisa chiyero chekushandisa.Izvo zvakanyanya kukanganisa ndezvi:
1. Nhamba yemashizha iduku, uye ndeye cantilever, saka simba racho harina kunaka, uye harigoni kushandiswa mumagetsi emagetsi epakati uye epamusoro.
2. Pamusana pehuwandu hwehuwandu hwekuyerera uye hupamhi hwepamusoro, hune hurefu hudiki hwekusveta kupfuura turbine yeFrancis pasi pemamiriro akafanana emusoro, zvichiita kuti pave nekudzika kukuru kwekuchera kwenheyo yechiteshi chemagetsi uye mari yakawanda.
Maererano nezvikanganiso zvataurwa pamusoro apa zveaxial flow turbines, yakakwirira-yakasimba anti-cavitation zvinhu zvitsva zvinoshandiswa mukugadzira turbine uye simba remashizha rinovandudzwa mukugadzirwa, kuitira kuti musoro wekushandisa we axial flow turbines urambe uchivandudzwa.Parizvino, musoro wekushandisa weaxial-flow paddle turbine ndeye 3 kusvika 90 m, uye yapinda munzvimbo yeFrancis turbine.Semuenzaniso, iyo yakanyanya single-unit inobuda yekunze axial-flow paddle turbines i181,700 kW, iyo yakanyanya musoro wemvura i88m, uye dhayamita yemhanyi i10.3m.Iyo yakawanda-yemuchina-muchina inobuda yeaxial-kuyerera paddle turbine inogadzirwa munyika yangu i175,000 kW, iyo yakanyanya musoro wemvura ndeye 78m, uye yakakura mumhanyi dhayamita i11.3m.Iyo axial-inoyerera yakagadziriswa-propeller turbine ine yakagadziriswa blades uye yakapusa chimiro, asi haigone kuchinjika kune hydropower zviteshi zvine shanduko huru mumusoro wemvura uye mutoro.Iyo ine yakagadzikana musoro wemvura uye inoshanda sechigadziko mutoro kana akawanda-mayuniti makuru-akawanda magetsi chiteshi.Kana simba remwaka rakawanda, kuenzanisa kwehupfumi kunogonekawo.Inogona kufungwa.Musoro wayo unoshanda we 3-50m.Axial-flow paddle turbines anowanzo shandisa zvigadziriso zvakamira.Maitiro ayo ekushanda akafanana neaFrancis turbines.Musiyano ndewekuti kana mutoro uchichinja, haungodzoreri kutenderera kwevanotungamira vanes., Paunenge uchigadzirisa kutenderera kwemashizha emumhanyi kuti uchengetedze kushanda kwepamusoro.
Kare, takaunzawo Francis turbines.Pakati pemajenareta eturbine, pachine musiyano mukuru pakati peFrancis turbines uye axial flow turbines.Semuenzaniso, chimiro chevamhanyi vavo chakasiyana.Mablades eFrancis turbines akada kufanana neshaft hombe, ukuwo axial flow turbines anenge akatarisana kune main shaft.
