[0019] For ease of understanding, combine here Figure 2-4 The specific structure and implementation effects of the present invention are further described as follows:
[0020] The specific structure of the present invention is as Figure 2-4 As shown, it is located in the annular space of the radial guide vane, at the position A of the tip of the positive guide vane 10, that is, at the transition section. An arc-shaped guide surface d is provided to make the fluid change smoothly. The arc on which the diversion surface d is located changes according to the law that the radius of curvature gradually decreases from the starting point to the ending point of the arc, and the arc can be simplified into two or more arcs. And as figure 2 and Figure 4 As shown, the anti-guide vane 20 adopts conformal transformation method and is designed according to the streamline. The radius of curvature of the blade bone line is gradually reduced from the beginning to the end of the arc, and the b...
