前言1985年8月初在湖南金竹山电厂现场,对上海汽轮机厂出产的高压5万千瓦汽轮机(电厂称一号机)发生的较剧烈振动进行了测试分析。该机组于1972年投运以来,运行基本正常,但在83年大修后不久,机组出现振动异常情况,在额定负荷状态下,汽轮机前轴承座和调门——油动机杠杆系统产生较为剧烈振动。电厂曾专此将转子怍了低速动平衡、前轴承由原来圆柱形改为抗振性能较

Preface In early August 1985 at the site of Hunan Jinzhushan Power Plant, a test was conducted on the more violent vibration of the high-pressure 50,000-MW turbine (No. 1 Power Plant) produced by the Shanghai Steam Turbine Plant. Since the unit was put into operation in 1972, its operation has basically been normal. However, shortly after overhaul in 1983, the unit experienced anomalous vibration. Under rated load conditions, the front bearing of the steam turbine and the valve-oil motive lever system produced relatively violent vibration. The power plant has dedicated this rotor 怍 low-speed dynamic balance, the former bearing instead of the original cylindrical to anti-vibration performance than
