ABSTRACT:
In a starting operation of a pump or a pump turbine with high head and large capacity, adjustable guide vanes are fully closed and compressed air is introduced within the runner casing to depress water around the runner. When the runner begins to rotate at a synchroous speed, the guide vanes are excessively opened to an over opening position where no reverse flow of the discharge flow occurs. After the stream of the discharge flow becomes steady, the guide vanes are moved conversely to a predetermined opening position where the maximum flow rate of the pump is obtained with low noise and low vibration.
The present invention relates to a starting operation for a pump or a pump turbine with adjustable guide vanes circumferencially arranged around the runner, and more particularly to a starting operation for a pump or a pump turbine which is operated by controlling the opening of the adjustable guide vanes.
