| Inhalt | Abstract Fluid driven valves are typically small and low priced components. Both, process stability and quality depend on their reliability. The main requirements of fluid driven valves are a high durability, a reproducible valve movement with leakage as small as possible when closed, and low pressure loss when opened. For a comprehensive examination of the mechanisms of the fluid driven valves motion and wear, extensive investigations of fluid driven pump valves were accomplished. Synchronously to data acquisition of system pressures, various high speed camera films were made, observing the valve motion through several optical accesses. In addition, fluid- and structural-dynamics were numerically simulated and verified by experimental data. Combining the results of measuring data, high-speed sequences and simulations, the phenomena during the opening of the valve and the mechanisms of wear due to cavitation in the valve gap have been confirmed and are now understood. |
