Split type impulse water turbine model runner measuring structure

The invention discloses a split type impulse water turbine model runner measuring structure which is composed of a support, a depth gauge, screws, a water bucket, bolts, nuts, cylindrical pins, a hub and gaskets. The water diversion blade of the water bucket abuts against the first prism plane of the support, a filler gauge is used for measuring the radial gap between the second prism plane of the support and the reference water bucket, a depth gauge is used for measuring the distance from the upper plane of the reference water bucket to the upper plane of the support, and the thickness of a gasket is adjusted to enable the measured value to meet design requirements. By adopting the measuring structure provided by the invention, the circumferential included angle, the radial size and the axial size between the water buckets can be accurately measured, the operation difficulty is reduced, the measuring precision is improved, the rotating wheel assembling precision is ensured, and the model test accuracy is imp
