摘要
Francis turbine wheel detour, which includes a short belt length and a short plate length, plus an oblique wing attack edge of a reverse curve, which is a combination of attack edge and bandwidth, and the combination of attack edge and crown in the rotation direction is expected,There is also a detour without bandwidth, including the shortened edge length and the shortened slope length, plus the attack edge of the reverse detour board. There is an attack edge angle at the outer edge of the detour line, and the front is the ground where the attack edge is connected with the crown in the direction of rotation. Another feature is that the back edge curve design reverses to the circular curve, thus shortening the length of the circular curve.
