Abstract
PURPOSE: To enable speedy and safe stop of revolution of a pump water-wheel by maintaining the turn of guide vane of the water-wheel pump at a fixed value even after the release of a dynamo from the power system.
CONSTITUTION: The turn of a guide vane 9 is reduced gradually by operation stop instruction, and also the input of a dynamo is also reduced. When the turn of the guide vane 9 is reduced at a fixed value or the input of the dynamo is reduced at a fixed value, the dynamo is released from the power system. Accordingly, the revolution speed of a main machine such as pump water-wheel begins to decrease gradually. At this time, the turn of the guide vane is not brought to zero position irrespective of continuous reduction and maintained at a fixed reduced turning position. Then, the pressurized water which flows down from a water pressure iron pipe 6 acts in the direction of braking the main machine, and the speed of revolution is reduced sharply and becomes nearly zero. At this time, the turn of the guide vane is brought at perfect closure position, and braking action is performed onto a dynamo.
