| Popis: | Vibrations of the basic assemblies of the hydrogen generator cause variable forces and loads that occurduring operation and depending on the operating mode. This paper presents some test results performed on a Kaplanvertical type turbine. Measurements were performed at 3 measuring points (N1, N2 and N3; Figure 1) using noncontactsensors, placed in pairs under 90 at each measuring point. Based on the measurements performed and theanalysis of the obtained results, the following can be concluded: hydraulic tests of the turbine were performed oninstruments that ensure high accuracy of these measurements. The tables show the absolute vibrations on thebearings of the hydro unit, as well as the vibrations of the turbine guide bearing |
