Embodiment Construction
[0018] The present invention is described in more detail below in conjunction with accompanying drawing example:
[0019] combine Figure 1-2 , using multiple positions of the steam turbine rotor for on-site dynamic balance structure design, on-site dynamic balance structure settings on the steam turbine rotor thrust disc, coupling output flange, rotor first-stage disc and last-stage disc, fully combined The bearing box cover, coupling cover, cylinder manhole and other structures make the operation feasible and meet the on-site dynamic balance requirements when the dynamic balance is greatly damaged.
[0020] The new on-site dynamic balance structure is designed inside the factory dynamic balance groove of the last stage of the rotor, so that it can be as close as possible to the final blade in the radial direction without affecting the structural strength of the wheel and the function of the high-speed dynamic balance groove for factory use, while ensuring its Operability, a...
