Example Embodiment
[0032] Example 1: Such as figure 1 , 2 As shown, a Francis turbine runner dynamic balance test method, the method includes the following steps: 1) cleaning and adjusting the dynamic balancing machine 1; 2) hoisting the tooling mandrel 2 to the dynamic balancing machine 1; 3) pairing the tooling Perform a dynamic balance test on the mandrel 2; 4) hoist the runner 3 and install it on the tooling mandrel 2; 5) perform a dynamic balance test on the tooling mandrel 2 and the runner 3 as a whole; 6) correct the upper crown of the runner 3 to recess The plane and the bottom plane of the lower ring are qualified.
[0033] Wherein, in the step 2), it specifically includes the following steps:
[0034] (1) Put the hoisting ring into the two ends of the tooling mandrel 2 and tighten it, then hoist the tooling mandrel 2 to the supporting position 4 of the dynamic balancer 1; remove the hoisting ring, and install the positioning flange 5 on one end of the tooling mandrel 2. , Connect the unive...
