摘要
QD128燃气轮机某台动力涡轮工厂试车时前支点振动值超过设计要求,影响机组安全运行。本文对机组试车过程监测数据和频谱进行了分析,在总结其振动特性的基础上,通过对燃气轮机转、静子结构的分析和研究,对加工和装配过程检测结果进行复查,制定了排故方案,经过多次试车验证,动力涡轮振动值符合设计规定要求,振动故障现象排除。
The EX-point vibration value exceed design requirement when One power turbine of QD 128 gas turbine has factory test , leading to unsafe operation of the unit plant .To solve the problem of vibration we analysis the monitoring date and analysis of spectrum during testing process ,and research the structure of static and rotor structural ,we also countercheck the machining and fitting processes , at the end we come to a conclusion .After many test validation , the vibration values of power turbine meet the design requirement ,the problem of vibration solved .
