Embodiment Construction
[0034] like figure 2 and image 3 As shown, the space curved guide vane of the water pump turbine mainly includes: an upper end surface (1), a lower end surface (2) and a ruled surface (3) composed of several straight lines between the upper and lower end surfaces. The connection point A between the guide vane water inlet (4) and the upper end surface (1) and the rotation center O of the guide vane on the upper end surface form a straight line OA, and the connection point A' between the guide vane water inlet edge (4) and the lower end surface (2) It is connected with the rotation center O' of the guide vane on the lower end surface to form a straight line O'A', and the straight line OA and the straight line O'A' are not parallel to each other and not in the same plane.
[0035] In the above implementation method, the water inlet side (4) of the guide vane is the high-pressure side of the guide vane, that is, the water flow inflow side of the turbine working condition.
