摘　　要：研究在烟气轮机转子上装一套主动平衡装置在线解决其振动过大的问题。为了将主动平衡技术运用于生产实际,以某炼油厂双级悬臂式烟气轮机为例进行有限元分析计算,通过比较4种单平面和3种双平面平衡的效果,确定了主动平衡装置的轴向安装位置及其所需的最大平衡能力。数值仿真验证表明利用该主动平衡装置,能有效地降低烟气轮机转子在工作转速下的振动。研究结果为烟气轮机转子上主动平衡装置的安装和试验提供了参考和依据,可用于指导解决工程实际中烟气轮机由于不平衡而引起的振动问题,提高烟气轮机转子的运行稳定性。A set of active balancing device is installed in flue gas expander rotor to solve the problem of excessive vibration. In order to apply the active balancing technology to practice, finite element analysis and calculation is carried out on the basis of a two-stage cantilever flue gas expander. Axial installation position and the required maximum balancing capacity of the active balancing device is determined through comparing the effects of four single plane and three double plane balances. Numerical simulation result shows that the vibration of flue gas expander rotor under operation rotating speed is effectively decreased with the active balancing device. The described method can be used to solve the vibration in flue gas expander caused by unbalance, and to increase the operation stability of flue gas expander rotor.
