本厂有台200MW汽轮机系哈尔滨汽轮机厂定型前第十二台产品,型号为N200-130/535/535一次中间再热,凝汽式、单轴、三排汽超高压汽轮机,1983年12月投产。1984年12月21日出现强烈振动而停机,以后经过几次处理虽有改善,但机组仍处于不稳定的控制运行中,前后损坏了2号轴承两台次,多次引起故障,造成被迫停机2098小时。到1985年5月,将机组的三个汽缸全部拆开,利用故障诊断技术,查明引起振动的原因,加以彻底处理,消除了机组振动,运行情况一直良好。一、振动历史概况该机在出厂时中压转子13至19级,级间隔板汽封齿处存在0.075mm的弯曲,在厂家进行低速动平衡吋,所加重量较多,并且在平衡
The factory has Taiwan 200MW turbine Harbin Steam Turbine plant stereotypes before the twelfth product model for the N200-130 / 535/535 once the reheat, condensing, single-shaft, three-row steam ultra-high pressure turbine, December 1983 Put into production. On December 21, 1984, there was a strong vibration and shut down. Although after several times of treatment, although the improvement was made, the unit was still under unstable control operation and damaged No. 2 bearing before and after, causing several failures and causing many failures Down 2098 hours. By May 1985, the three cylinders of the unit were completely disassembled. Fault diagnosis technology was used to identify the cause of the vibration and thoroughly deal with the vibration of the unit, and the operation condition has been good. First, the history of the vibration history The aircraft at the factory 13 to 19 intermediate pressure rotor, grade seal at the tooth seal there 0.075mm bending, the manufacturers of low-speed dynamic balance inches, more weight added, and the balance
