20.500.12556/DKUM-89602 Izračun dvižnih sil in izdelava PZI tehnične dokumentacije za gradnjo pomožne zapornice turbinskih vtokov HE Formin magistrsko delo Calculation of lift forces and preparation of PFC technical documentation for construction of the auxiliary gate for the Turbine Inlets of HPP Formin V podjetju Dravske elektrarne Maribor d. o. o. se pri remontu posameznih turbinskih sklopov v hidroelektrarnah uporabljajo pomožne zapornice turbinskih vtokov. Magistrsko delo se osredotoča na zadnjo hidroelektrarno slovenskega ozemlja na reki Dravi, to je hidroelektrarna Formin. V preteklosti so se zapleti pojavljali pri dvigu pomožnih zapornic po remontu, pri čemer so se pojavile prevelike sile trenja. Treba je bilo rekonstruirati zapornice, zato je v magistrskem delu predstavljen preračun dvižnih sil, delujočih na pomožno zapornico tako pri maksimalnem pretoku kot tudi pri delnih pretokih. Glede na preračun dvižnih sil smo izbrali konceptno rešitev s kolesi. V kolesih lahko uporabimo različne ležaje, zato smo v magistrskem delu opravili tudi preračun sil trenja za izbrane vrste ležajev. Izbran je bil kotalni ležaj, ki zagotavlja najmanjše trenje. V magistrskem delu je bila pripravljena tudi celotna PZI dokumentacija nove konceptne rešitve pomožne zapornice turbinskih vtokov s kotalnimi kolesi za hidroelektrarno Formin. At the company Dravske Elektrarne Maribor d. o. o., auxiliary gates for turbine inlets are used during the overhaul of individual turbine assemblies in hydroelectric power plants. This master's thesis focuses on the last hydroelectric power plant on Slovenian territory along the Drava river, which is the Formin Hydroelectric Power Plant. In the past, complications arose during the lifting of auxiliary gates after an overhaul due to excessive friction forces. Reconstruction of the gates was necessary, and thus this thesis presents the calculation of lifting forces acting on the auxiliary gate at maximum and partial flow rates. Based on the calculation of lifting forces, a conceptual solution with wheels was selected. Different types of bearings can be used in wheels, so this thesis also includes a calculation of friction forces for the selected types of bearings. A rolling bearing, which ensures minimal friction, was chosen. Additionally, the complete PZI documentation for the new conceptual solution of the auxiliary gate for turbine inlets with rolling wheels for the Formin Hydroelectric Power Plant was prepared in the continuation of the master's thesis. hidroelektrarna Formin pomožna zapornica turbinski vtok dvižne sile tekalno kolo PZI dokumentacija Formin Hydroelectric Power Plant auxiliary gate turbine inlet lifting forces rolling wheel PFC documentation true true false [R.
