Ulwazi oluyisisekelo lwe-hydropower kanye ne-hydro generator

1. Ukuhlukaniswa kwamandla kanye nebanga le-hydro generator
Njengamanje, alikho izinga elihlanganisiwe lokuhlukaniswa kwamandla kanye nesivinini se-hydro generator emhlabeni.Ngokwesimo sase-China, amandla ayo kanye nesivinini kungahlukaniswa ngokulandela ithebula elilandelayo:
Amandla akalwe ngokwezigaba PN (kw) akalwe isivinini NN (R / min);
Isivinini esiphansi, isivinini esiphakathi kanye nesivinini esikhulu;
Ijeneretha ye-Micro hydro <100 750-1500;
I-generator encane ye-hydro 100-500 <375-600 750-1500;
I-generator ye-hydro enosayizi omaphakathi 500-10000 <375-600 750-1500;I-hydro generator enkulu > 10000 < 100-375 > 375;

2. Uhlobo lokufakwa kwesakhiwo se-hydro generator
Isakhiwo sokufakwa kwe-hydro generator ngokuvamile sinqunywa uhlobo lwe-hydraulic turbine.Kukhona ikakhulukazi izinhlobo ezilandelayo:

1) Isakhiwo esivundlile
Amajeneretha e-Hydro anesakhiwo esivundlile ngokuvamile aqhutshwa ama-turbines ashukumisayo.Amayunithi e-turbine yamanzi avundlile ngokuvamile asebenzisa ama-bearings amabili noma amathathu.Ukwakheka kwama-bearings amabili kunezinzuzo zobude obufushane be-axial, isakhiwo esihlangene nokufakwa okulula nokulungiswa.Kodwa-ke, lapho isivinini esibucayi se-shafting singakwazi ukuhlangabezana nezidingo noma umthwalo wokuthwala mkhulu, isakhiwo sokuthwala ezintathu sidinga ukwamukelwa.Amayunithi amaningi akhiqiza i-hydraulic turbine generator angaphansi kwamayunithi amancane naphakathi nendawo.Amayunithi amakhulu avundlile anomthamo we-12.5mw nawo akhiqizwa.Amayunithi aphehla ugesi wenjini yamanzi avundlile akhiqizwa phesheya ayivelakancane enamandla angu-60-70mw, kuyilapho amayunithi aphehla ugesi weturbine yamanzi avundlile aneziteshi zamandla ezimpontshwa zokugcina amandla angaba neyunithi eyodwa yomthamo wama-300MW.

2) Isakhiwo esiqondile
Isakhiwo esime mpo sisetshenziswa kakhulu kumayunithi akhiqiza i-turbine yamanzi asekhaya.Amayunithi ajeneretha enjini yamanzi aqondile ngokuvamile ashayelwa uFrancis noma ama-axial-flow turbines.Isakhiwo esime mpo singahlukaniswa ngohlobo lokumiswa kanye nohlobo lwesambulela.I-thrust bear yejeneretha 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-tubular turbine generator 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 isiqondiso sokugeleza sihambisana nepayipi lokungena kanye nepayipi lokuphuma le-turbine.I-Tubular Hydrogenerator inezinzuzo zesakhiwo esihlangene nesisindo esincane.Isetshenziswa kakhulu eziteshini zamandla ezinekhanda eliphansi lamanzi.

3. Izingxenye zesakhiwo se-hydro generator
Ijeneretha ye-hydro emile ikakhulukazi ihlanganisa i-stator, i-rotor, uhlaka olungaphezulu, uhlaka oluphansi, i-thrust bear, i-guide bear, i-air cooler kanye ne-turbine yamagnetic unomphela.
