Conclusions

  1. 1.

    The pressure in the space before the runner of turbines of bulb units is mainly a function of the reduced discharge and opening of the gate apparatus, and therefore the characteristics obtained for the PLK-548 and PLK-984 can be used when analyzing the operation of other turbines similar in specific speed.

     
  2. 2.

    The nonuniformity of the pressure distribution in the cross section before the runner of a bulb turbine is less than that of a vertical turbine of the same type for the same regimes with respect to QI′ and nI′.

     
  3. 3.

    If the high-vacuum zone during the transient process reaches a critical value, it can be avoided by assigning an appropriate regulating regime.
