1. Ukwahlukaniswa kwamandla kanye nezinga lejeneretha yamanzi
Njengamanje, ayikho indinganiso ehlanganisiwe yokuhlukaniswa kwamandla kanye nesivinini sejeneretha yamanzi emhlabeni. Ngokwesimo saseShayina, amandla ayo kanye nesivinini kungahlukaniswa cishe ngokwethebula elilandelayo:
Amandla alinganisiwe okuhlukaniswa kwe-PN (kw) isivinini esilinganisiwe se-NN (R / min);
Isivinini esiphansi, isivinini esiphakathi kanye nesivinini esiphezulu;
Ijeneretha yamanzi encane < 100 750-1500;
Ijeneretha encane yamanzi 100-500 < 375-600 750-1500;
Ijeneretha yamanzi ephakathi nendawo 500-10000 < 375-600 750-1500; Ijeneretha yamanzi enkulu > 10000 < 100-375 > 375;
2, Uhlobo lwesakhiwo sokufakwa kwejeneretha yamanzi
Isakhiwo sokufakwa kwejeneretha yamanzi sivame ukunqunywa uhlobo lwe-hydraulic turbine. Kunezinhlobo ezilandelayo ikakhulukazi:
1) Isakhiwo esivundlile
Amajeneretha e-hydro anesakhiwo esivundlile avame ukuqhutshwa ama-turbine e-impulse. Amayunithi e-turbine yamanzi avundlile avame ukusebenzisa ama-bearings amabili noma amathathu. Isakhiwo sama-bearings amabili sinezinzuzo zobude obufushane be-axial, isakhiwo esihlangene kanye nokufakwa nokulungiswa okulula. Kodwa-ke, lapho ijubane elibalulekile lokushafa lingakwazi ukuhlangabezana nezidingo noma umthwalo wokuthwala umkhulu, isakhiwo sama-bearings amathathu sidinga ukwamukelwa. Amayunithi amaningi ejeneretha e-hydraulic turbine yasekhaya angowamayunithi amancane naphakathi nendawo. Amayunithi amakhulu avundlile anomthamo ongu-12.5mw nawo akhiqizwa. Amayunithi ejeneretha e-turbine yamanzi avundlile akhiqizwa kwamanye amazwe awavamile anomthamo ongu-60-70mw, kuyilapho amayunithi ejeneretha e-turbine yamanzi avundlile aneziteshi zamandla zokugcina ezipompiwe angaba nomthamo weyunithi eyodwa ongu-300MW.
2) Isakhiwo esiqondile
Isakhiwo esiqondile sisetshenziswa kabanzi kumayunithi ejeneretha ye-turbine yamanzi yasekhaya. Amayunithi ejeneretha ye-turbine yamanzi aqondile avame ukuqhutshwa yi-Francis noma ama-turbine e-axial-flow. Isakhiwo esiqondile singahlukaniswa ngohlobo lokumiswa kanye nohlobo lwesambulela. I-thrust bearing yejeneretha etholakala engxenyeni engenhla ye-rotor ibizwa ngokuthi uhlobo olumisiwe, kanti i-thrust bearing etholakala engxenyeni engezansi ye-rotor ibizwa ngokuthi uhlobo lwesambulela.
3) Isakhiwo se-Tubular
Iyunithi yokukhiqiza i-turbine eshubhu iqhutshwa yi-turbine eshubhu. I-turbine eshubhu iwuhlobo olukhethekile lwe-turbine egeleza nge-axial enama-runner blades agxilile noma alungisekayo. Isici sayo esiyinhloko ukuthi i-runner axis ihlelwe ngokuvundlile noma ngokugobile, futhi isiqondiso sokugeleza sihambisana nesepayipi lokungena kanye nepayipi lokukhipha le-turbine. I-Tubular Hydrogenerator inezinzuzo zesakhiwo esiqinile kanye nesisindo esincane. Isetshenziswa kabanzi eziteshini zamandla ezinekhanda lamanzi eliphansi.
3, Izingxenye zesakhiwo sejeneretha yamanzi
Ijeneretha ye-hydro eqondile ihlanganisa kakhulu i-stator, i-rotor, uhlaka olungaphezulu, uhlaka oluphansi, i-thrust bearing, i-guide bearing, i-air cooler kanye ne-permanent magnet turbine.
