Dynamic field balancing is performed to reduce the rotating force of a rotor on-site. A balance issue is one of the most common sources of vibration issues that occur at a facility. Field balancing is an economical approach to reducing the vibration and extending the life of the equipment. This approach to balancing also takes in consideration the operating parameters, which may affect the balance of the rotor. Thermal and process variables can cause vibration issues that must be considered to increase the reliability of the equipment and operate at peak efficiency.
