Jenareta yemagetsi inogadzirwa ne ...
Tsanangudzo yeFrancis turbine musanganiswa weinjini ye "impulse" ne "reaction turbine", apo maburi anotenderera achishandisa simba re "reaction" ne "impulse" remvura inoyerera nepakati pawo zvichiburitsa magetsi zvinobudirira. Francis turbine inoshandiswa kugadzira magetsi kazhinji muzviteshi zvemagetsi zvepakati nepakati kana zvikuru.
Maturbine aya anogona kushandiswa pamisoro yakadzika semamita maviri uye yakakwirira semamita mazana matatu. Pamusoro pezvo, maturbine aya anobatsira sezvo anoshanda zvakanaka zvakaenzana kana akaiswa mudenga sezvaanoita kana akatarisa mudenga. Mvura inopinda nepaFrancis turbine inorasikirwa nekumanikidzwa, asi inoramba iri padanho rakafanana, saka inoonekwa se reaction turbine.
Tsananguro yedhayagiramu huru ye turbine yega yega yeFrancis ndeiyi inotevera.
Kesi Yekutenderera
Kaburi kemuchina we spiral ndiyo nzira yekupinda mvura mu turbine. Mvura inoyerera kubva mudura kana dhamu inopfuudzwa nepaipi iyi nekumanikidzwa kwakanyanya. Mapazi ema turbine akaiswa mudenderedzwa, zvinoreva kuti mvura inorova mapazi e turbine inofanira kuyerera mudenderedzwa kuti irove zvakanaka. Saka kaburi kemuchina we spiral kanoshandiswa, asi nekuda kwekufamba kwemvura, inorasikirwa nekumanikidzwa kwayo.
Kuti kuchengetedze kumanikidzwa kwakafanana, dhayamita yekesi inoderedzwa zvishoma nezvishoma, nokudaro, simba kana kumhanya kwakafanana kunorova maburi ekumhanya.
Gara Vanes
Mavane ekugara uye kutungamira anotungamira mvura kuenda kumablades ekumhanya. Mavane ekugara anoramba akamira panzvimbo yawo uye anoderedza kutenderera kwemvura nekuda kwekuyerera kweradial, sezvo ichipinda mumablades ekumhanya, nokudaro, zvichiita kuti turbine ishande zvakanaka.
Vane dzeGwara
Mavhiri ekufambisa haamire, anochinja kona yawo zvichienderana nezvinodiwa kuti adzore kona yekurova kwemvura kuenda kumashizha eturbine kuti awedzere kushanda zvakanaka. Anodzorawo mwero wekufamba kwemvura mumashizha ekumhanya nokudaro achidzora simba rinobuda muturbine zvichienderana nemutoro uri paturbine.
Mabhana ekumhanya
Mabhachi erunner ndiwo moyo wechero turbine yeFrancis. Aya ndiwo mapoinzi apo mvura inorova uye simba rekubata rinoita kuti shaft yeturbine itenderere, zvichiburitsa torque. Kunyatsotarisa magadzirirwo ema angle e blade pakupinza nekubuda kwemhepo kwakakosha, sezvo aya ari ma parameter makuru anokanganisa kugadzirwa kwesimba.
Mapadza emumhanyi ane zvikamu zviviri. Hafu yepasi yakagadzirwa muchimiro chebhaketi diki kuti itenderedze turbine nekushandisa simba remvura. Asi chikamu chepamusoro chemapadza chinoshandisa simba remvura rinoyerera nepakati paro. Mumhanyi anotenderera nepakati pemasimba aya maviri.
Chubhu yeDraw
Kumanikidzwa pakubuda kwemuchina wekuita turbine kunowanzova kushoma pane kumanikidzwa kwemhepo. Mvura pakubuda, haigone kuburitswa zvakananga kumutsara wemashure. Chubhu kana pombi yenzvimbo iri kuwedzera zvishoma nezvishoma inoshandiswa kuburitsa mvura kubva pakubuda kweturbine kuenda kumutsara wemashure.
Chubhu iyi iri munzvimbo iri kuwedzera inonzi Draft Tube. Mugumo mumwe wechubhu wakabatana nepanobuda mvura. Zvisinei, mumwe mugumo wakanyudzwa pasi pemvura iri mumutsara wekumashure.
Francis Turbine Kushanda Nehurongwa Hwayo Nedhizaini
Maturbine eFrancis anoshandiswa nguva dzose mumafekitori emagetsi emvura. Mumafekitori aya, mvura ine simba guru inopinda mufekitori kuburikidza nekaburi kehozhwa (volute). Kufamba uku kunoderedza simba remvura sezvainomonereka nepachubhu; zvisinei, kumhanya kwemvura kunoramba kusina kuchinja. Mushure mekupfuura nepachubhu, mvura inoyerera nepamaguide vanes uye inonangidzirwa kumapanga emumhanyi pamakona akakodzera. Sezvo mvura ichiyambuka mapanga akakombama emumhanyi, mvura inotsauswa zvishoma. Izvi zvinoita kuti mvura irasikirwe nechikamu chekufamba kwayo "kwekutenderera". Mvura inotsauswawo munzira ye axial kuti ibude muchubhu inodhonza kuenda kumusana.
Chubhu yataurwa inoderedza kumhanya kwemvura kuti iwane simba rakawanda kubva mumvura inopinzwa. Maitiro emvura achitsauswa kuburikidza nemabhurazi anomhanyisa anoguma nesimba rinosundira mabhurazi kune rimwe divi sezvo mvura ichitsauswa. Simba iroro rekuita (sezvatinoziva kubva mumutemo wechitatu waNewton) ndiro rinoita kuti simba ritakurwe kubva mumvura kuenda kumugodhi weturbine, zvichiramba zvichitenderera. Sezvo turbine ichifamba nekuda kwesimba iroro rekuita, maturbine eFrancis anozivikanwa sematurbine ekuita. Maitiro ekuchinja mafambiro emvura anoderedzawo kumanikidzwa mukati meturbine pachayo.
Zvakanakira Chigadzirwa
1. Kugona kugadzirisa zvinhu zvakakwana. Zvakadai se5M CNC VTL OPERATOR, 130 & 150 CNC floor boring machines, constant temperature annealing furnace, planer milling machine, CNC machining centre etc.
2.Hupenyu hwakagadzirwa hunopfuura makore makumi mana.
3. Forster inopa sevhisi yemahara kamwe chete, kana mutengi akatenga mayuniti matatu (kukwanisa ≥100kw) mukati megore rimwe chete, kana huwandu hwese huri pamusoro pemayuniti mashanu. Sevhisi yenzvimbo inosanganisira kuongororwa kwemidziyo, kuongororwa kwenzvimbo itsva, kudzidziswa kwekuisa nekugadzirisa nezvimwewo,.
4.OEM yakagamuchirwa.
5. Kugadzira CNC, kuyedzwa kwesimba uye kushandiswa kwe isothermal annealing, bvunzo yeNDT.
6. Kugona Kugadzira neR&D, mainjiniya vakuru gumi nematatu vane ruzivo mukugadzira nekutsvaga.
7. Nyanzvi yezvehunyanzvi kubva kuForster yakashanda pa hydro turbine yakanyoreswa kwemakore makumi mashanu uye yakapihwa Chinese State Council Special Allowance.
