| 摘要 |
A method and system for balancing a rotating machinery operation at or near resonance, wherein the rotating machinery has an inner frame, an outer casing, and counterweights connected with a shaft of the rotating machinery, comprising: mounting a proximity probe (310) on the outer casing; mounting a first plurality of velocity transducers (320) on the inner frame; mounting a second plurality of velocity transducers (330) on the outer casing; connecting the proximity probe, the first and second plurality of velocity transducers to a data acquisition system (340); collecting vibration data provided by the proximity probe, and the first and second plurality of velocity transducers, using the data acquisition system (350); removing the outer casing to allow access to the counterweights (360); and adjusting the counterweights using a predetermined rotor influence coefficient (370) to reduce the vibration below an acceptable threshold level.
