Kune akawanda marudzi ema hydro generator.Nhasi, ngatizivise iyo axial-flow hydro jenareta zvakadzama.Iko kushandiswa kweaxial-flow hydro jenareta mumakore achangopfuura ndiko kunonyanya kuvandudzwa kwemusoro wemvura yakakwirira uye saizi yakakura.Iko kuvandudza kwedzimba axial-flow turbines zvakare nekukurumidza.Kune marudzi maviri eaxial-flow paddle turbines akaiswa mune yakavakirwa Gezhouba hydropower station, imwe ine mumhanyi dhayamita ye11.3m, inova dhayamita yemhanyi yematurbine akafanana munyika.Hezvino zvakanakira uye zvakaipira zvepakati axial kuyerera turbine.
Zvakanakira axial kuyerera turbine
Kuenzaniswa naFrancis turbine, axial-flow turbine ine zvinotevera zvakakosha zvakanaka:
1. High chaiyo kumhanya uye kunaka simba hunhu.Naizvozvo, kumhanya kwayo kweyuniti uye kuyerera kweyuniti kwakakwira kupfuura iyo yaFrancis turbine.Pasi pemusoro mumwechete uye mamiriro ekubuda, inogona kuderedza zvakanyanya saizi ye hydraulic turbine generator unit, kuderedza uremu hweyuniti uye kuchengetedza kushandiswa kwezvinhu, saka ine hupfumi hwehupfumi.
2. Chimiro chepamusoro uye hutsinye hwepamusoro hwemumhanyi mablades e-axial-flow turbine zviri nyore kuzadzisa zvinodiwa mukugadzira.Nekuti mablades eaxial flow propeller turbine anogona kutenderera, avhareji yekushanda yakakwira kupfuura yeFrancis turbine.Apo mutoro uye musoro zvinoshanduka, kushanda kunochinja zvishoma.
3. Mashizha emumhanyi eaxial flow paddle turbine anogona kuparadzaniswa kuti afambise kugadzira uye kutakura.
Naizvozvo, iyo axial-flow turbine inoramba yakatsiga muhukuru hwekushanda, ine kushoma vibration, uye ine hunyanzvi hwepamusoro uye kubuda.Muchikamu chemusoro wemvura yakaderera, inenge ichitsiva Francis turbine.Mumakumi emakore achangopfuura, yakaita budiriro huru uye yakafara kushandiswa maererano neiyo imwechete unit huwandu uye musoro wemvura.
3, Kuipa kweaxial flow turbine
Nekudaro, iyo axial-flow turbine zvakare ine zvipingamupinyi uye inomisa chiyero chekushandisa.Zvakaipa zvayo zvikuru ndezvi:
1. Nhamba yemashizha iduku uye cantilever, saka simba racho rakashata uye harigoni kushandiswa kune mashizha emagetsi emagetsi epakati nepamusoro.
2. Nekuda kweiyo huru yeyuniti inoyerera uye yakakwirira yeyuniti kumhanya, ine diki yekukweva kureba kupfuura Francis turbine pasi pemusoro mumwe chete wemvura, zvichikonzera kudzika kwakakura kwekuchera uye mari yakakwira yenheyo yechiteshi chemagetsi.
Zvinoenderana nekukanganisa kuri pamusoro kweaxial-flow turbine, musoro wekushandisa weaxial-flow turbine unoramba uchivandudzwa nekutora zvinhu zvitsva zvine simba rakakura uye cavitation kuramba mukugadzira turbine nekuvandudza mamiriro ekushushikana kwemablades mukugadzira.Parizvino, iyo application head range yeaxial flow propeller turbine ndeye 3-90 m, iyo yakapinda munzvimbo yeFrancis turbine.Semuenzaniso, kubuda kwe * * * kamwe muchina wekunze axial flow propeller turbine i181700 kW, iyo * * * musoro i88m, uye dhayamita remumhanyi i10.3M.Iyo imwechete inobuda yeaxial flow propeller turbine inogadzirwa kuChina i175000 kW, iyo * * * musoro i78m, uye dhayamita ye * * * mumhanyi i11.3m.Axial inoyerera yakagadziriswa propeller turbine ine mashizha akagadzika uye chimiro chakareruka, asi haigone kuchinjika kune hydropower zviteshi zvine shanduko huru mumusoro wemvura uye mutoro.Kune zviteshi zvakakura zvemagetsi emvura ane musoro wakagadzikana wemvura uye uchishanda sechigadziko kana akawanda mayuniti, inogona zvakare kutariswa mushure mekuenzanisa kwehupfumi kana mwaka wemagetsi simba rakawanda.Musoro wayo wemvura unoshanda uri 3-50m.Axial flow propeller turbine inowanzo tora vertical mudziyo, uye kushanda kwayo kwakangofanana neiyo yaFrancis turbine, Musiyano ndewekuti kana mutoro uchichinja, haungodzore kutenderera kwegidhi vane, asi zvakare inodzora kutenderera kweiyo runner blade kuchengetedza kushanda kwepamusoro.
Takasumawo turbine yaFrancis kare.Pakati pema hydro generator, iyo Francis turbine yakasiyana zvakanyanya kubva kune axial-flow turbine.Semuenzaniso, maitiro emumhanyi wavo akasiyana.Mablades aFrancis turbine anenge akaenzana neaya main shaft, ukuwo ayo eaxial flow turbine anenge akatarisana kune main shaft.
