Isakhiwo kanye nesakhiwo sokufakwa kwe-hydraulic turbine
Isethi yejeneretha ye-turbine yamanzi iyinhliziyo yohlelo lwamandla kagesi. Ukuzinza nokuvikeleka kwayo kuzothinta ukuzinza nokuvikeleka kwalo lonke uhlelo lwamandla kanye nokuzinza kokuphakelwa kukagesi. Ngakho-ke, sidinga ukuqonda ukwakheka kwesakhiwo kanye nesakhiwo sokufakwa kwe-turbine yamanzi, ukuze ibe usizo ekunakekeleni nasekulungiseni okuvamile. Nasi isingeniso esifushane sesakhiwo se-hydraulic turbine.
Isakhiwo se-hydraulic turbine
Ijeneretha ye-Hydro yakhiwa i-rotor, i-stator, ifreyimu, i-thrust bear, i-guide bear, i-cooler, i-brake nezinye izingxenye eziyinhloko; I-stator ngokuyinhloko yakhiwe ifreyimu, i-iron core, i-winding nezinye izingxenye; I-stator core yenziwe ngamashidi ensimbi e-silicone abandayo, angenziwa abe yisakhiwo esibalulekile nesihlukanisiwe ngokuvumelana nezimo zokukhiqiza nezokuthutha; Ijeneretha ye-turbine yamanzi ngokuvamile ipholiswa ngomoya ovaliwe ojikelezayo. Iyunithi yomthamo omkhulu kakhulu ivamise ukusebenzisa amanzi njengendawo yokupholisa ukuze ipholise ngokuqondile i-stator. Ngesikhathi esifanayo, i-stator ne-rotor amayunithi akhiqiza amanzi aphindwe kabili angaphakathi okupholisa i-turbine generator.
Isakhiwo sokufakwa kwe-hydraulic turbine
Isakhiwo sokufakwa kwe-hydro generator ngokuvamile sinqunywa uhlobo lwe-hydraulic turbine. Kukhona ikakhulukazi izinhlobo ezilandelayo:
1. Isakhiwo esivundlile
Ijeneretha ye-hydraulic turbine enesakhiwo esivundlile ngokuvamile iqhutshwa i-impulse turbine. Iyunithi ye-hydraulic turbine enezingqimba ngokuvamile ithatha ama-bearings amabili noma amathathu. Isakhiwo sama-bearings amabili sinobude obufushane be-axial, isakhiwo esihlangene kanye nokufakwa okulula nokulungiswa. Kodwa-ke, lapho isivinini esibucayi se-shafting singakwazi ukuhlangabezana nezidingo noma umthwalo othwalayo mkhulu, isakhiwo sokuthwala ezintathu sidinga ukwamukelwa, Amayunithi amaningi afuywayo we-hydraulic turbine generator amayunithi amancane naphakathi nendawo, kanye namayunithi amakhulu avundlile anamandla we-12.5mw nawo akhiqizwa. Amayunithi aphehla ugesi we-hydraulic turbine generator akhiqizwa phesheya anamandla angama-60-70mw awavamile, kuyilapho amayunithi ejeneretha ejeneretha ye-hydraulic turbine eneziteshi zamandla ezimpontshwayo anomthamo owodwa ongu-300MW;
2. Isakhiwo esiqondile
Amayunithi akhiqiza i-turbine yamanzi asekhaya asetshenziswa kabanzi esakhiweni esime mpo. Amayunithi ajeneretha enjini yamanzi aqondile ngokuvamile ashayelwa uFrancis noma ama-axial-flow turbines. Isakhiwo esime mpo singahlukaniswa ngohlobo olumisiwe kanye nohlobo lwesambulela. I-thrust bear ye-generator etholakala engxenyeni engenhla ye-rotor ngokuhlangene ibizwa ngokuthi uhlobo olumisiwe, futhi i-thrust bear etholakala engxenyeni engezansi ye-rotor ibizwa ngokuhlangene ngokuthi uhlobo lwesambulela;
3. Isakhiwo se-Tubular
Iyunithi ye-turbine generator ye-tubular iqhutshwa yi-tubular turbine. I-tubular turbine iwuhlobo olukhethekile lwe-axial-flow turbine enama-runner blades angaguquki noma alungisekayo. Isici sawo esiyinhloko ukuthi i-axis yomgijimi ihlelwe ngokuvundlile noma ngokugobile futhi ihambisana nokuqondisa kokugeleza kwamapayipi okungena kanye nokuphuma kwe-turbine. I-generator ye-turbine ye-tubular inezinzuzo zesakhiwo esihlangene nesisindo esincane, Isetshenziswa kakhulu eziteshini zamandla ezinekhanda lamanzi aphansi.
Lezi yisakhiwo sokufaka kanye nesakhiwo sokufakwa kwe-hydraulic turbine. Isethi yejeneretha ye-turbine yamanzi iyinhliziyo yamandla esiteshini samandla kagesi. Ukulungiswa nokugcinwa okujwayelekile kuzokwenziwa ngokuhambisana nemithetho nemithethonqubo. Esimeni sokusebenza okungavamile noma ukwehluleka, kufanele sihlaziye ngokwesayensi nangokunengqondo futhi siklame uhlelo lokulungisa ukuze sigweme ukulahlekelwa okukhulu.
