Abstract:Cilj naloge je določiti najvišjo možno temperaturo reke Drave pri kateri je zaprt hladilni sistem še sposoben hladiti in držati agregat pod kritično temperaturo. Z izvedbo analitičnega preračuna smo preverili sposobnost hlajenja temperaturno najobčutljivejšega dela turbinskega sistema (nosilnega ležaja) in na podlagi dobljenih rezultatov predlagali možne izboljšave. Ugotovili smo, da je najvišja temperatura reke Drave, pri kateri je še mogoče nemoteno obratovanje brez kakršnihkoli sprememb hladilnega sistema 22,5 °C. V primeru, da bi povečali število plošč ploščnega toplotnega prenosnika nosilnega ležaja in pretok hladilne tekočine, bi lahko zagotovili ustrezno hlajenje agregata tudi pri temperaturi rečne vode 24 °C.
Keywords:Kaplanova turbina, zaprt hladilni sistem, ploščni toplotni prenosnik

Title:Calculation of the Kaplan turbine cooling system
Abstract:The objective was to determine the highest possible temperature of the Drava River at which the closed cooling system is still able to keep the aggregate below the critical temperature. By carrying out an analytical calculation, we checked the cooling ability of the most temperature-sensitive part of the turbine system (the carrier bearing) and proposed possible improvements based on the obtained results. The maximum temperature of the River Drava at which operating is still possible without any modification of the cooling system was found to be 22.5 °C. If the number of plates of the plate heat exchanger of the carrier bearing and the flow of the cooling liquid were increased, adequate cooling of the unit could be ensured even at a river water temperature of 24 °C.
Keywords:Kaplan turbine, closed cooling system, plate heat exchanger
