Ngaphezu kwemingcele yokusebenza, ukwakheka kanye nezinhlobo ze-hydraulic turbine ezethulwe ezihlokweni ezedlule, kulesi sihloko, sizokwethula izinkomba zokusebenza nezici ze-hydraulic turbine. Lapho ukhetha i-hydraulic turbine, kubalulekile ukuqonda ukusebenza kwe-hydraulic turbine. Okulandelayo, sizokwethula imingcele yenkomba yokusebenza ehambisanayo nezici ze-hydraulic turbine.
Inkomba yokusebenza ye-hydraulic turbine
1. Amandla alinganiselwe: asetshenziselwa ukuveza umthamo we-hydro generator, ku-kW. Amandla alinganiselwe ahlukaniswe ngokusebenza kahle akufanele abe makhulu kunokukhishwa kweshaft ye-hydro turbine;
2. I-voltage elinganiselwe: i-voltage elinganiselwe ye-hydro generator izonqunywa ngokuqhathanisa kobuchwepheshe nezomnotho ngokuhlanganyela nomkhiqizi. Njengamanje, amandla kagesi we-hydro generator asuka ku-6.3kV aye ku-18.0kv. Umthamo omkhulu, uyanda umthamo we-voltage olinganisiwe;
3. Isici samandla esilinganisiwe: isilinganiso samandla asebenzayo alinganisiwe we-generator kumandla abonakalayo alinganisiwe, ku-COS φ N kubonisa ukuthi iziteshi zikagesi ezikude nesikhungo somthwalo ngokuvamile zamukela isici samandla aphezulu, futhi izindleko zemoto zingancishiswa kancane lapho isici samandla sikhuphuka.
Izici ze-hydraulic turbine
1. Isiteshi samandla esigcina amandla sidlala indima enkulu yokulawula umthwalo ophezulu kanye nokugcwaliswa kwesigodi kugridi yamandla. Iyunithi iqala futhi ime njalo. Isakhiwo se-generator motor kufanele sicabange ngokugcwele amandla ayo aphindaphindiwe e-centrifugal, okubangela ukukhathala ezintweni zesakhiwo kanye noshintsho olushisayo nokwanda okushisayo ku-stator kanye ne-rotor windings. I-stator ivame ukusebenzisa ukufakwa kwe-thermoelastic;
2. Isiphephetha-moya esikurotha ye-hydro generator evamile ye-generator generator motor ayikwazi ukuhlangabezana nezidingo zokuchithwa kokushisa nokupholisa, futhi ifeni ye-peripheral ngokuvamile isetshenziselwa amayunithi anamandla amakhulu nesivinini esikhulu;
3. Ifilimu kawoyela ye-thrust bearing kanye ne-guide bear ngeke yonakale ngesikhathi sokuzungezisa okuhle nokubi;
4. Isakhiwo sihlobene eduze nemodi yokuqala. Uma i-motor yokuqala isetshenziswa, i-motor ifakwe ku-coaxial. Uma kudingekile ukuguqula isivinini se-generator motor, ngaphezu kokushintsha isigaba samandla, kuyadingeka futhi ukushintsha i-stator winding kanye nesigxobo se-rotor.
Lezi yizinkomba zokusebenza kanye nezici ze-turbine yamanzi. Ngaphezu kwemingcele yokusebenza eyinhloko, ukuhlukaniswa, ukwakheka kanye nesakhiwo sokufakwa kwe-hydraulic turbine eyethulwe ngaphambili, ukwethulwa kokuqala kwe-hydraulic turbine sekuphelile. Isethi yokuphehla ugesi wamanzi iyisisetshenziswa esibalulekile samandla kagesi kanye nengxenye ebalulekile embonini yokuphehla ugesi ngamanzi. Ngesikhathi esifanayo, futhi iyithuluzi elibalulekile lokusebenzisa ngokugcwele amandla ahlanzekile navuselelekayo ukuze kuzuzwe ukongiwa kwamandla kanye nokunciphisa ukungcola kanye nokunciphisa ukungcoliswa kwemvelo. Esikhathini sokwandisa ukunaka ekuvikelweni kwemvelo, kukholakala ukuthi amayunithi aphehla ugesi azoba namathemba amakhulu emakethe.
