石板塘电站2号立式水轮发电机组旋转中心调整工艺改进

Improvement of Rotation Center Adjustment Process for Vertical Water Turbine Generator Set in Shibantang Hydropower Station

立式水轮发电机组的旋转中心是否合格,对机组运行时的各部摆度、振动及导轴瓦温度等安全运行指标有着重要影响。根据石板塘水电站2号机组的结构特点,通过层层控制,对继往的旋转中心的调整工艺进行了改进,力求机组处于理想的旋转中心,以使其更安全稳定地运行。

Qualified rotation center of the vertical turbine generator is important to the safety operation indexes of the unit swing,vibration and the temperature of the guide bearing. In this case,according to the structure characteristics of the unit,through layer control,the adjustment process of the rotating center is improved to make the unit in the ideal rotating center,which ensures the safe and steady operation.
