I-Alternative Energy Hydroelectric Generator 500KW Francis Hydro Turbine Generator in Uzbekistan
Incazelo ye-Francis turbine iyinhlanganisela yakho kokubili i-impulse kanye ne-reaction turbine, lapho ama-blades ezungeza kusetshenziswa kokubili ukusabela namandla okuguquguquka kwamanzi agelezayo kuwo akhiqiza ugesi ngokuphumelelayo. I-Francis turbine isetshenziselwa ukukhiqiza ugesi kaningi eziteshini eziphehla ugesi ezimaphakathi noma ezinkulu.
Lawa ma turbines angasetshenziselwa amakhanda aphansi njengamamitha ama-2 futhi ukuphakama kwawo kube ngamamitha angama-300. Ukwengeza, lawa ma turbines anenzuzo njengoba esebenza ngokulinganayo uma emiswe ngokuvundlile njengoba enza uma emiswe mpo. Amanzi ahamba ngenjini yomoya kaFrancis alahlekelwa ingcindezi, kodwa ahlala enesivinini esingaphezulu noma esingaphansi, ngakho-ke angathathwa njenge-reaction turbine.
Incazelo yomdwebo ngamunye wengxenye eyinhloko ye-Francis turbine imi kanje.
I-Spiral Casing
I-spiral casing iyindawo engenisa amanzi ku-turbine. Amanzi agelezayo esuka endaweni yokugcina amanzi noma edamini enziwa ukuthi adlule kuleli payipi ngomfutho omkhulu. Ama-blades ama-turbines abekwe ngokuyindilinga, okusho ukuthi amanzi ashaya izindwani ze-turbine kufanele ageleze e-eksisi eyindilinga ukuze ashaye kahle. Ngakho-ke i-spiral casing isetshenziswa, kodwa ngenxa yokunyakaza okuyisiyingi kwamanzi, ilahlekelwa ukucindezela kwayo.
Ukugcina ingcindezi efanayo ububanzi be-casing buyancipha kancane kancane, ngaleyo ndlela, umfutho ofanayo noma isivinini esishaya ama-runner blades.
Hlala Vanes
Hlala futhi uqondise ama-vanes aqondisa amanzi kuma-runner blades. Ama-vanes ahlala emile endaweni yawo futhi anciphisa ukushwibeka kwamanzi ngenxa yokugeleza kwe-radial, njengoba engena kuma-runner blades, ngaleyo ndlela, enze i-turbine isebenze kahle kakhulu.
Mqondise uVanes
Ama-vane omhlahlandlela awamile, ashintsha i-engeli yawo ngokwemfuneko yokulawula i-engeli yokushaywa kwamanzi abe ama-turbine blades ukuze kwandiswe ukusebenza kahle. Ziphinde zilawule izinga lokugeleza kwamanzi ku-runner blades ngaleyo ndlela zilawule ukuphuma kwamandla e-turbine ngokuya ngomthwalo ophuma ku-turbine.
Ama-Runner Blades
Ama-Runner blades ayinhliziyo yanoma iyiphi i-Francis turbine. Lezi yizikhungo lapho uketshezi lushaya khona namandla okuthinta okuthinta abangela ukuthi i-shaft ye-turbine ijikeleze, ikhiqize i-torque. Ukunaka kakhulu ukwakheka kwama-engeli e-blade ekungeneni nasekuphumeni kuyadingeka, njengoba lezi kuyimingcele emikhulu ethinta ukukhiqizwa kwamandla.
Ama-runner blades anezingxenye ezimbili. Ingxenye engezansi yenziwe ngendlela yebhakede elincane ukuzungezisa i-turbine ngokusebenzisa isenzo samanzi. Ngenkathi ingxenye engenhla yama-blades isebenzisa amandla okuphendula amanzi ageleza kuwo. Umgijimi uzungeza kulawa mandla amabili.
I-Draft Tube
Ingcindezi ekuphumeni komgijimi we-turbine yokusabela ngokuvamile ingaphansi komfutho womoya. Amanzi ekuphumeni, awakwazi ukukhishelwa ngqo ku-tailrace. Ishubhu noma ipayipi lendawo ekhula kancane kancane isetshenziselwa ukukhipha amanzi ekuphumeni kwe-turbine kuya ku-tailrace.
Leli shubhu lendawo ekhulayo libizwa ngokuthi i-Draft Tube. Umkhawulo owodwa weshubhu uxhunywe endaweni yokuphuma yomgijimi. Nokho, omunye umkhawulo ucwiliswe ngaphansi kwezinga lamanzi emjahweni womsila.
UFrancis Turbine Isimiso Sokusebenza Ngomdwebo
Ama-turbines kaFrancis asetshenziswa njalo ezimbonini zamandla kagesi ngamanzi. Kulezi zitshalo zamandla, amanzi anengcindezi ephezulu angena ku-turbine ngegobolondo lomnenke (i-volute). Lokhu kunyakaza kunciphisa umfutho wamanzi njengoba egoqa ngeshubhu; nokho, isivinini samanzi asishintshile. Ngemva kokudlula ivolothi, amanzi ageleza phakathi kwama-vane aqondisayo futhi aqondiswe kuma-blade omgijimi ngama-engeli angcono kakhulu. Njengoba amanzi ewela izindwani ezigobile ngokunembile zomgijimi, amanzi ayaphambukiswa kancane emaceleni. Lokhu kwenza amanzi alahlekelwe ingxenye ethile “yokuvunguza” kwawo. Amanzi aphinde aphambukiswe ku-axial ukuze aphume eshubhu elisalungiswa aye emjahweni womsila.
Ishubhu elishiwo linciphisa ijubane lokuphuma kwamanzi ukuze lithole inani eliphakeme lamandla emanzini afakwayo. Inqubo yokuphambukiswa kwamanzi ngokusebenzisa ama-runner blades kubangela amandla aqhubezela ama-blades ngakolunye uhlangothi njengoba amanzi ephambuka. Lawo mandla okusabela (njengoba sazi emthethweni wesithathu ka-Newton) yiwo enza amandla ukuthi athwalwe esuka emanzini aye kushafu we-turbine, aqhubeke nokuzungezisa. Njengoba i-turbine ihamba ngenxa yalawo mandla okusabela, izinjini zomoya ze-Francis zikhonjwa njengama-reaction turbines. Inqubo yokushintsha isiqondiso sokugeleza kwamanzi nayo yehlisa ingcindezi ngaphakathi kwe-turbine ngokwayo.
