Ivanovski, Dejan (avtor), Senegačnik, Andrej (mentor), Novak, Lovrenc (komentor)

V zaključni nalogi obravnavamo možnosti snovanja in izdelave Bankijeve turbine z uporabo aditivnih tehnologij, natančneje 3D-tiska plastomerov. Poleg upoštevanja utemeljenih enačb in kriterijev dimenzioniranja so zajete tudi potrebne prilagoditve ter omejitve tehnologij, ki neposredno vplivajo na obratovalne karakteristike vodnega stroja. Ugotovljeno je bilo, da je povsem izvedljivo izdelati modularni model turbine, ki je nato integriran v obstoječi merilni postaji Bankijevih turbin. Temu sledi vrsta eksperimentov ter obravnava vpliva spremembe dejavnikov, kot so debelina in število lopatic gonilnika ter višina šobe, s katero določamo vstop curka na gonilnik. Z izvedenimi meritvami smo ugotovili, da je kljub nižjim izkoristkom v primerjavi s konvencionalnimi modeli možno eksperimentalno določiti optimalno rešitev s kombiniranjem naštetih parametrov.

Izvleček

In this thesis, we explore the possibilities of designing and manufacturing a Banki turbine using additive technologies, specifically 3D printing of plastomers. In addition to considering the established equations and dimensioning criteria, the necessary adjustments and limitations of the technologies that directly affect the operational characteristics of the water machine are also addressed. It was found that it is entirely feasible to produce a modular model of the turbine, which is then integrated into the existing measurement station for Banki turbines. This is followed by a series of experiments and an analysis of the impact of varying factors such as the thickness and number of driver blades and the height of the nozzle, which determines the entry of the jet onto the driver. The measurements conducted revealed that, despite lower efficiencies compared to conventional models, it is possible to experimentally determine the optimal solution by combining the mentioned parameters.
