Pressures in the runner zone of a hydroelectric station with bulb units
Conclusions 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.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 $ Q_{I} $′ and $ n_{I} $′.If the high-vacuum zone during the transient process reaches a critical value, it can be avoided by assigning an appropriate regulating regime.
