Recent developments in the design of high head pump/turbines
- Voith Hydro, Inc., York, PA (US)
The design of high head pump/turbines requires unique considerations because of severe operating conditions, such as turbine peaking, frequent starting and stopping turbining, pump starts, synchronous condensing, etc. The optimum pump/turbine design is a balance between performance, structural integrity, manufacturability, ease of installation, long term reliability and equipment cost. The optimization process is dependent upon design considerations such as allowable stress levels, deflections and vibration amplitude and frequency. The hydraulic and mechanical design optimization of such major components as the stay ring/spiral case, discharge ring, wicket gates, impeller, shaft and wearing ring/seals is discussed in this paper relative to recent design developments.
