Kune mhando dzakawanda dzemajenareta emagetsi emvura. Nhasi, ndichazivisa zvakadzama nezvemajenareta emagetsi emvura ekufamba kweaxial. Kushandiswa kwemajenareta emagetsi ekufamba kweaxial mumakore achangopfuura kunonyanya kugadzirwa kwemusoro murefu nehukuru hwakakura. Maturbine emumba ekufamba kweaxial ari kukura nekukurumidza. Maturbine maviri emhando yeaxial-flow paddle akaiswa paGezhouba Hydropower Station akavakwa. Rimwe rawo rine dhayamita yemamita 11.3, iro parizvino ndiro rakakura kupfuura mamwe ose pasi rose. . Heano mabhenefiti nezvakaipa zvematurbine ekufamba kweaxial.
Mabhenefiti e axial flow turbine
Zvichienzaniswa neFrancis turbines, axial flow turbines dzine mabhenefiti makuru anotevera:
1. Kumhanya kwakanyanya uye hunhu hwakanaka hwesimba. Nokudaro, kumhanya kwayo uye kufamba kweyuniti kwakakwira kupfuura kweye Francis turbine. Pasi pemvura yakafanana nemamiriro ezvinhu akafanana, inogona kuderedza zvikuru saizi yeyuniti inogadzira turbine, kuderedza huremu hweyuniti, uye kuchengetedza kushandiswa kwezvinhu, saka inodhura zvishoma.
2. Chimiro chepamusoro uye kuomarara kweganda rerunner blade re axial flow turbine zvinogona kusangana zviri nyore nezvinodiwa mukugadzirwa. Nekuti mapanga e axial-flow rotary-paddle turbine anogona kutenderera, avhareji yekushanda kwepamusoro pane iyo ye mixed-flow turbine. Kana mutoro nemusoro wemvura zvikachinja, kushanda hakuchinji zvakanyanya.
3. Mabhandi emuchina we axial-flow paddle turbine anogona kugurwa, izvo zviri nyore kugadzira nekutakura.
Saka, axial flow turbine inogona kuchengetedza kugadzikana munzvimbo yakakura yekushanda, nekudengenyeka kushoma, uye kushanda zvakanaka uye kubuda kwepamusoro. Munzvimbo yakaderera, inenge yatsiva turbine yeFrancis. Mumakumi emakore achangopfuura, zvese maererano nekugona kweyuniti imwe chete uye kushandiswa kwemusoro wemvura, kwave nekuvandudzwa kukuru, uye kushandiswa kwayo kwakafarawo.
Zvakaipa zve axial flow turbine
Zvisinei, axial flow turbine inewo zvikanganiso uye inoderedza kushanda kwayo. Zvikanganiso zvikuru ndeizvi:
1. Huwandu hwemapanga esimbi hudiki, uye hahuna simba rakawanda, saka simba rayo harina kunaka, uye haigone kushandiswa munzvimbo dzemagetsi emvura dziri pakati nepakati nepamusoro.
2. Nekuda kwehuwandu hukuru hwekuyerera kwemagetsi uye kumhanya kwakanyanya kwemagetsi, ine hurefu hudiki hwekusveta kupfuura turbine yeFrancis iri pasi pemusoro mumwe chete, zvichikonzera kudzika kukuru kwekuchera hwaro hwechiteshi chemagetsi uye mari yakawanda.
Zvichienderana nezvikanganiso zvataurwa pamusoro apa zvematurbine ekufamba nemhepo axial, zvinhu zvitsva zvinorwisa cavitation zvine simba guru zvinoshandiswa mukugadzira maturbine uye simba remablades rinovandudzwa mukugadzira, kuitira kuti musoro wekushandisa wematurbine ekufamba nemhepo axial urambe uchivandudzwa. Parizvino, musoro wekushandisa weturbine yekufamba nemhepo axial-flow i3 kusvika 90 m, uye yapinda munzvimbo yeturbine yeFrancis. Semuenzaniso, huwandu hwepamusoro hwematurbine ekunze axial-flow paddle i181,700 kW, musoro wemvura wakanyanya i88m, uye dhayamita yerunner i10.3m. Hunhu hwepamusoro hwematurbine ekufamba nemhepo axial-flow paddle anogadzirwa munyika yangu i175,000 kW, musoro wemvura wakanyanya i78m, uye dhayamita yepamusoro yerunner i11.3m. Turbine ye axial-flow fixed-propeller ine mablades akagadzika uye chimiro chiri nyore, asi haigone kuchinjika kuma hydropower stations ane shanduko huru mumusoro wemvura nemutoro. Ine musoro wemvura wakasimba uye inoshanda senzvimbo yesimba kana nzvimbo yemagetsi ine mayuniti akawanda. Kana simba remwaka rakawanda, kuenzanisa kwehupfumi kunogonekawo. Inogona kufungwa nezvayo. Hurefu hwemusoro wayo hunoshanda i3-50m. Maturbine eAxial-flow paddle anowanzo shandisa zvishandiso zvakamira. Maitiro ayo ekushanda akafanana neematurbine eFrancis. Musiyano ndewekuti kana mutoro uchichinja, haungotungamiriri kutenderera kwemavane ekutungamira chete. , Ukuwo uchigadzirisa kutenderera kwemablades erunner kuti urambe uchishanda zvakanaka.
Kare, takatangawo kugadzira ma turbine eFrancis. Pakati pema turbine generators, kuchine musiyano mukuru pakati pema turbine eFrancis nema axial flow turbines. Semuenzaniso, chimiro chema runners avo chakasiyana. Ma blades ema turbine eFrancis anenge akafanana ne main shaft, nepo ma axial flow turbine anenge akatarisana ne main shaft.
