Conclusions

  1. 1.

    One of the causes of periodically varying disturbing forces in the blading of a pump-turbine during its operation as a pump is the peripheral nonuniformity of the flow at the runner outlet due to hydrodynamic wakes from the blades.

     
  2. 2.

    The dynamic moments on the guide apparatus vanes of a reversible machine in the turbine regime are apparently the result of the opposite effect of the rotating blade system on the fixed cascade of the guide apparatus located at a distance of (0.05–0.16)t, where t is the cascade pitch from the edges of the runner blades.

     
  3. 3.

    Investigations showed the need to take into account the alternating dynamic moments acting on the vanes in the pump and turbine regimes when designing the guide apparatus of a reversible machine.

     
  4. 4.

    Pressure fluctuations in the pump regime have a tendency to increase slightly with decrease of the anticavitation margin, which is not observed in the turbine regime.
