The object of the present invention is to provide a kind of multistage pump return guide vanes for increasing runner and runner to increase method, on solving
Problem of the existing technology is stated, the return guide vane runner after increasing can play the role of axial diversion, and having improves diversion effect,
Improve the effect of hydraulic performance.
To achieve the above object, the present invention provides following schemes: it is anti-that the present invention provides a kind of multistage pump for increasing runner
Guide vane, including increase cover board and blade, the blade are provided with multiple, and multiple blades are fixed on described increase on cover board；
Described increase is provided with multiple contour planes on cover board.
Preferably, the convex side of the blade of the blade, blade concave side and it is described increase cover board increase shape between cover board bottom surface
At runner is increased, for supplying water, stream passes through.
Preferably, the contour plane is provided with 10-15.
Preferably, the spacing distance of the adjacent contour plane is height/(number -1 of contour plane) always increased.
Preferably, the cover board bottom surface of increasing successively is increased along runner direction.
The runner that a kind of multistage pump return guide vane for increasing runner is also disclosed in the present invention increases method, including following step
It is rapid:
1), multiple contour planes are successively made to the right from increasing on the left of cover board；
2), successively on multiple contour planes, curved section is drawn；
3) it, is fitted to multiple curved sections and increases cover board bottom surface；
4), by the convex side of blade, blade concave side and increase cover board bottom surface and formed and increase runner.
Preferably, the contour plane is provided with 10, and the curved section drafting has 10 sections.
The present invention achieves following technical effect compared with the existing technology:
The present invention increases cover board bottom surface and successively increases along runner direction, plays the role of having to improve and leading along axial diversion
Effect is flowed, the effect of hydraulic performance is improved.
