Practical Balancing of a MS3002 Twin-rotor Gas Turbine Based on Vibration Analysis

The impact of vibration phenomena on gas turbine operation and production quality can significantly reduce their service life. Balancing the rotating elements of these machines is a valuable method for reducing production losses and avoiding the need for total machine dismantling. In this study, a gas turbine type MS3002 with two rotors was examined on-site to minimize the phenomenon of unbalance and provide correction angles at the rotor level. This balancing process enabled the control and improvement of the mass distribution of the rotor to maintain efforts and vibrations caused by unbalance within acceptable limits while ensuring the optimal operation of the turbine. The results demonstrate the importance of balancing techniques in extending the service life of gas turbines and maintaining optimal performance.
