摘要

针对两跨四支撑汽轮机组、压缩机组等轴系中各跨转子动平衡合格,但安装试车后仍发生轴系不平衡振动故障的问题,研究各跨转子残余不平衡量耦联效应对轴系转子振动特性的影响。搭建了两跨四支撑(2N支撑)轴系实验台,模拟开机启动过程,实验对比了针对轴系转子系统的两种低速动平衡方式。实验结果表明,对两跨四支撑转子整体进行组合的低速动平衡效果优于对转子1、2单独进行低速动平衡。
        For a two-span four-supported steam turbine unit, compressor unit and other shafting systems, the dynamic balance of each rotor is qualified, but unbalanced vibration faults of the shafting still occur after the test run. The coupling effect of the residual unbalanced coupling of each trans-rotor on the vibration characteristics of the shafting rotor has been studied in this work. A two-span four-support(2 N support) shafting test rig was built to simulate the start-up process. Two low-speed dynamic balancing methods for the shafting rotor system were compared. The experimental results show that the combined low-speed dynamic balancing effect of the two-span four-support rotor is better than that of the rotors 1 or 2 alone.
