Embodiment Construction

[0011] The present invention will be further described below in conjunction with the embodiments: the manufacturing process of the runner body with the runner body core of a large-scale bulb tubular hydroelectric generator set in a power station, and the runner body is composed of the runner body body and the runner body core , the manufacturing process includes:

[0012] The processing steps of the runner body core: forging; rough turning; quality test; semi-finished turning; quality flaw detection; finish turning; marking; boring; drilling; Boring positioning pin holes; pliers, clamping pins; boring, boring blade shaft holes with the runner body; pliers. The core of the runner body is a special part on the new structure runner body. Its material is ZG20SiMn, and the requirements for quenching and tempering treatment after rough turning of the workpiece are added, which not only improves the mechanical properties of the material, but also ensures the product quality of the wo...
