Sekundarni naslov: | Influence parameters analyse of hydrodynamical axial bearing of turbine runnershaft |
Sekundarni povzetek: | Hydrodynamic shaft seal is a mandatory part of every water turbine. It is meant to prevent breach of river water in between rotated and stationary turbine parts by means of creating sealing conditions by implementation of adequate mechanical parts construction and controlled cooling water quantity. Conditions of adequate lubrication of sliding surface are in correlation with hydrologic parameters of water turbine and sealing insert design. My graduation work concentrates on research of: - how the sealing insert shall be designed in order to fulfill the requirement of uniform pressure on the sliding surface, - how to reach uniform and continued inflow of adequate cooling water to sliding surface, - how the pressure conditions on the sliding surface are being changed during transitions in turbine operation (site measurements) The goal of this graduation work is to describe essential parameters of axial hydrodynamic seal during stationary and key transitional regimes of operation on the basis of the analysis of practical measurements results and theoretical calculations results, and to design adequate sealing insert form accordingly. |
