Abstract

PURPOSE: To prevent cavitation, by alternately replacing a half number of guide vanes by fixed members and rendering constant the angle of inflow to a runner by the fixed members.
CONSTITUTION: Each moving guide vane 3 is located between the fixed members 6 to perform opening and closing. When the moving guide vane is entirely closed, it comes into contact with the fixed members 6 as shown by the two-dot chain line. Because water flows along the fixed members 6 at any degree of opening of the moving guide vane 3, the angle of inflow to the runner is constant. This results in preventing cavitation when a small load is applied.
