Jenereta ya Mphamvu Yamagetsi Yowonjezera Mphamvu Yogwiritsa Ntchito Madzi ya 500KW Francis Hydro Turbine Generator ku Uzbekistan
Tanthauzo la turbine ya Francis ndi kuphatikiza kwa turbine ya impulse ndi reaction, komwe masamba amazungulira pogwiritsa ntchito mphamvu ya reaction ndi impulse ya madzi omwe akuyenda mkati mwake ndikupanga magetsi bwino kwambiri. Turbine ya Francis imagwiritsidwa ntchito popanga magetsi nthawi zambiri m'malo opangira magetsi apakati kapena akuluakulu.
Ma turbine awa angagwiritsidwe ntchito pa mitu yotsika mpaka mamita awiri ndi kutalika mpaka mamita 300. Kuphatikiza apo, ma turbine awa ndi othandiza chifukwa amagwira ntchito mofanana akayikidwa molunjika monga momwe amachitira akayang'aniridwa molunjika. Madzi omwe amadutsa mu turbine ya Francis amataya mphamvu, koma amakhalabe pa liwiro lomwelo, kotero amaonedwa ngati turbine yoyankhira.
Kufotokozera kwa chithunzi chachikulu cha turbine iliyonse ya Francis ndi motere.
Chophimba Chozungulira
Chivundikiro chozungulira ndi malo olowera madzi kupita ku turbine. Madzi otuluka kuchokera ku dziwe amapangidwa kuti adutse mu chitolirochi ndi mphamvu yayikulu. Masamba a ma turbine amayikidwa mozungulira, zomwe zikutanthauza kuti madzi omwe akukhudza masamba a turbine ayenera kuyenda mu mzere wozungulira kuti agwire bwino. Chifukwa chake chivundikiro chozungulira chimagwiritsidwa ntchito, koma chifukwa cha kuyenda kozungulira kwa madzi, chimataya mphamvu yake.
Kuti mphamvu ya chivundikirocho ikhale yofanana, kukula kwa chivundikirocho kumachepa pang'onopang'ono, motero, mphamvu kapena liwiro lofanana limagunda masamba othamanga.
Khalani ndi Ma Vane
Ma Vane Okhazikika ndi Otsogolera Amatsogolera Madzi Ku Masamba Othamanga. Ma Vane Okhazikika Amakhazikika pamalo awo ndipo amachepetsa kuzungulira kwa madzi chifukwa cha kuyenda kwa radial, pamene akulowa mu Masamba Othamanga, motero, zimapangitsa kuti turbine ikhale yogwira ntchito bwino.
Ma Vane Otsogolera
Ma vane otsogolera sakhazikika, amasintha ngodya yawo malinga ndi zofunikira kuti azitha kuwongolera ngodya yolumikizira madzi ndi masamba a turbine kuti awonjezere magwiridwe antchito. Amawongoleranso kuchuluka kwa madzi omwe amalowa m'mabawo othamanga motero amawongolera mphamvu ya turbine malinga ndi katundu womwe uli pa turbine.
Masamba Othamanga
Mabala othamanga ndi mtima wa turbine iliyonse ya Francis. Awa ndi malo omwe madzi amagunda ndipo mphamvu yozungulira ya turbine imapangitsa kuti shaft ya turbine izungulire, zomwe zimapangitsa kuti mphamvu ifike. Kuyang'anitsitsa kapangidwe ka ma angles a blade polowera ndi potulukira ndikofunikira, chifukwa awa ndi magawo akuluakulu omwe amakhudza kupanga mphamvu.
Masamba othamanga ali ndi magawo awiri. Gawo la pansi limapangidwa ngati chidebe chaching'ono kuti lizungulire turbine pogwiritsa ntchito mphamvu ya madzi. Pomwe gawo lapamwamba la masamba limagwiritsa ntchito mphamvu ya madzi yomwe ikuyenda mkati mwake. Wothamangayo amazungulira kudzera m'mphamvu ziwirizi.
Chubu Choyesera
Kupanikizika komwe kumatuluka kwa turbine yoyankhira nthawi zambiri kumakhala kochepa kuposa kupsinjika kwa mpweya. Madzi omwe amatuluka sangatulutsidwe mwachindunji kupita ku tailrace. Chubu kapena chitoliro cha malo omwe akuwonjezeka pang'onopang'ono chimagwiritsidwa ntchito kutulutsa madzi kuchokera kutuluka kwa turbine kupita ku tailrace.
Chitolirochi cha malo okulira chimatchedwa Draft Tube. Malekezero ena a chitolirochi amalumikizidwa ndi malo otulukira a wothamanga. Komabe, malekezero ena amamira pansi pa mulingo wa madzi mu mpikisano wa mchira.
Mfundo Yogwirira Ntchito ya Francis Turbine Yokhala ndi Chithunzi
Ma turbine a Francis amagwiritsidwa ntchito nthawi zonse m'mafakitale opanga magetsi amadzi. M'mafakitale amenewa, madzi amphamvu kwambiri amalowa mu turbine kudzera mu chipolopolo cha nkhono (volute). Kusunthaku kumachepetsa kuthamanga kwa madzi pamene akuzungulira mu chubu; komabe, liwiro la madzi silisintha. Pambuyo podutsa mu volute, madziwo amadutsa m'ma vane otsogolera ndipo amalunjika ku masamba a wothamanga pamakona abwino kwambiri. Popeza madziwo amadutsa masamba opindika bwino a wothamanga, madziwo amapatutsidwa pang'ono. Izi zimapangitsa madzi kutaya gawo lina la kayendedwe kake ka "kuzungulira". Madziwo amapatutsidwanso mbali ina kuti atuluke mu chubu chowongolera kupita ku mpikisano wa mchira.
Chubu chomwe chatchulidwachi chimachepetsa liwiro la madzi kuti apeze mphamvu zambiri kuchokera ku madzi olowera. Njira yopititsira madzi kudzera mu masamba othamanga imapangitsa mphamvu yomwe imayendetsa masambawo kumbali ina pamene madzi akupotozedwa. Mphamvu yochitira zimenezo (monga momwe tikudziwira kuchokera ku lamulo lachitatu la Newton) ndiyo imapangitsa mphamvu kunyamulidwa kuchokera m'madzi kupita ku shaft ya turbine, kupitiriza kuzungulira. Popeza turbine imayenda chifukwa cha mphamvu yochitira zimenezo, ma turbine a Francis amadziwika kuti ndi ma turbine ochitira. Njira yosinthira njira ya madzi imachepetsanso kuthamanga kwa turbine yokha.
Ubwino wa Zamalonda
1. Mphamvu yokonza zinthu zambiri. Monga makina obowola pansi a CNC a 5M, makina obowola pansi a CNC a 130 ndi 150, ng'anjo yotenthetsera kutentha kosasintha, makina opukusira a planer, malo opangira machining a CNC ndi zina zotero.
2. Moyo wokhazikika ndi zaka zoposa 40.
3. Forster imapereka chithandizo chaulere cha malo kamodzi kokha, ngati kasitomala agula mayunitsi atatu (mphamvu ≥100kw) mkati mwa chaka chimodzi, kapena ndalama zonse ndi zoposa mayunitsi 5. Chithandizo cha malo chimaphatikizapo kuyang'anira zida, kuyang'ana malo atsopano, kuyika ndi kuphunzitsa kukonza ndi zina zotero.
4.OEM yalandiridwa.
5.CNC machining, dynamic balance tested ndi isothermal annealing processed, NDT test.
6. Kapangidwe ndi Kufufuza ndi Kupititsa Patsogolo, mainjiniya akuluakulu 13 omwe ali ndi luso pakupanga ndi kufufuza.
7. Katswiri wa zaukadaulo wochokera ku Forster adagwira ntchito pa turbine yamadzi yomwe idaperekedwa kwa zaka 50 ndipo adapereka Chinese State Council Special Allowance.
