Alternative Energy Hydroelectric Generator 500KW Francis Hydro Turbine Generator in Uzbekistan
Tanthauzo la Francis turbine ndi kuphatikiza kwa turbine yamphamvu komanso momwe ma turbine amachitira, pomwe masamba amazungulira pogwiritsa ntchito momwe madzi amayendera komanso mphamvu yamadzi yomwe ikuyenda mkati mwake ndikupanga magetsi bwino. Francis turbine imagwiritsidwa ntchito popanga magetsi nthawi zambiri m'malo opangira magetsi apakatikati kapena akulu.
Ma turbines awa amatha kugwiritsidwa ntchito ngati mitu yotsika mpaka 2 metres komanso kutalika kwa 300 metres. Kuphatikiza apo, ma turbines awa ndi opindulitsa chifukwa amagwira ntchito mofanana akaikidwa mopingasa monga momwe amachitira akayang'ana molunjika. Madzi odutsa mu turbine ya Francis amataya mphamvu, koma amakhala pa liwiro lomwelo, ndiye kuti amatengedwa ngati turbine.
Kufotokozera kwa chithunzi chilichonse cha turbine ya Francis ndi motere.
Spiral Casing
The spiral casing ndiye njira yolowera madzi kupita ku turbine. Madzi otuluka kuchokera ku dziwe kapena damu amapangidwa kuti adutse paipi iyi ndi kuthamanga kwambiri. Masamba a ma turbines amayikidwa mozungulira, zomwe zikutanthauza kuti madzi omwe akumenya masamba a turbine ayenera kuyenda mozungulira mozungulira kuti amenye bwino. Chifukwa chake chotchinga chozungulira chimagwiritsidwa ntchito, koma chifukwa cha kayendedwe ka madzi ozungulira, amataya mphamvu yake.
Kusunga kupanikizika komweko m'mimba mwake ya casing imachepetsedwa pang'onopang'ono, motero, kuthamanga kofanana kapena kuthamanga kumagunda masamba othamanga.
Khalani Vanes
Khalani ndi kuwongolera mavane amawongolera madzi kupita ku masamba othamanga. Mavane okhazikika amakhalabe pamalo awo ndipo amachepetsa kuthamanga kwa madzi chifukwa cha kutuluka kwa ma radial, pamene amalowa muzitsulo zothamanga, motero, kupanga turbine yabwino kwambiri.
Guide Vanes
Mavane owongolera sayima, amasintha ngodya yawo molingana ndi kufunikira kowongolera momwe madzi akukantha kukhala ma turbine masamba kuti awonjezere mphamvu. Amayang'aniranso kuchuluka kwa madzi muzitsulo zothamanga motero amawongolera mphamvu ya turbine malinga ndi katundu wa turbine.
Runner Blades
Masamba othamanga ndi mtima wa turbine iliyonse ya Francis. Awa ndi malo omwe madzi amagunda komanso mphamvu yamphamvu yamphamvu yomwe imapangitsa kuti shaft ya turbine izungulire, kutulutsa torque. Ndikofunikira kuyang'anitsitsa kapangidwe ka ma angles a blade polowera ndi potuluka, chifukwa izi ndizinthu zazikulu zomwe zimakhudza kupanga magetsi.
Masamba othamanga ali ndi magawo awiri. Theka lapansi limapangidwa ngati chidebe chaching'ono kuti chizungulire turbine pogwiritsa ntchito mphamvu yamadzi. Pamene kumtunda kwa masamba ntchito anachita mphamvu ya madzi oyenda mwa izo. Wothamanga amazungulira kupyola mphamvu ziwirizi.
Draft Tube
Kupsyinjika pa kutuluka kwa wothamanga wa turbine ya reaction nthawi zambiri kumakhala kochepa poyerekeza ndi mpweya wa mumlengalenga. Madzi akutuluka, sangathe kutulutsidwa mwachindunji ku tailrace. Chubu kapena chitoliro cha malo omwe akuchulukira pang'onopang'ono amagwiritsidwa ntchito potulutsa madzi kuchokera ku turbine kupita ku tailrace.
Chubu ichi cha malo ochulukirapo chimatchedwa Draft Tube. Mbali imodzi ya chubu imalumikizidwa ndi kutuluka kwa wothamanga. Komabe, mapeto enawo amamizidwa pansi pa mlingo wa madzi mu mpikisano wa mchira.
Francis Turbine Mfundo Yogwira Ntchito Ndi Chithunzi
Francis turbines amagwiritsidwa ntchito pafupipafupi m'mafakitale opangira magetsi opangira magetsi. M'mafakitale amagetsi awa, madzi othamanga kwambiri amalowa mu turbine kudzera mu chipolopolo cha nkhono (volute). Kuyenda uku kumachepetsa kuthamanga kwa madzi pamene akupiringa kudzera mu chubu; komabe, liwiro la madzi silinasinthe. Pambuyo podutsa mu volute, madzi amayenda kudzera muzitsulo zowongolera ndipo amalunjika ku masamba a othamanga pamakona abwino kwambiri. Popeza kuti madzi amadutsa masamba opindika ndendende a wothamanga, madzi amapatutsidwa chammbali. Izi zimapangitsa madzi kutaya gawo lina la kayendedwe kake ka "kamvuluvulu". Madziwo amapatutsidwanso kupita ku axial kuti atuluke mu chubu chothamangira kupita ku mpikisano wamchira.
Chubu chotchulidwachi chimachepetsa kuthamanga kwa madzi kuti apeze mphamvu zambiri kuchokera m'madzi olowera. Njira yamadzi yomwe imapatutsidwa kudzera muzitsulo zothamanga imapangitsa kuti pakhale mphamvu yomwe imayendetsa masambawo kumbali ina pamene madzi akuphwanyidwa. Mphamvu yamachitidwe (monga tikudziwira kuchokera ku lamulo lachitatu la Newton) ndi yomwe imapangitsa mphamvu kunyamulidwa kuchokera kumadzi kupita ku tsinde la turbine, kupitiriza kuzungulira. Popeza turbine imayenda chifukwa cha mphamvuyi, ma turbines a Francis amadziwika ngati ma reaction turbines. Njira yosinthira momwe madzi amayendera imachepetsanso kuthamanga mkati mwa turbine yokha.
