ABSTRACT:
A method and apparatus for balancing a turbine rotor (10) is disclosed. The invention utilizes an existing equilibrium pipe (17) in the turbine, and changes the structure of the turbine in such a manner that the pipe (17) can be extended with a sleeve (17a), so that a linear passageway (21) is created from the turbine rotor (10), at a point where the rotor is to be balanced (11), to the exterior of the turbine (20). The sleeve (17a) is capped and plugged during operation of the rotor (10). To insert a balancing weight (25), the sleeve (17a) is uncapped and unplugged and the weight (25) is passed through the sleeve (17a) and positioned within the rotor (10).
