引起水力机组扩大振动的干扰力有:机械的,水力的和电动的。振动时由转子质量引起离心力,当水轮机的工作轮,发电机转子和励磁机转子不平衡时发生。水轮机工作轮应在工厂或安装时加以静力平衡。作为水力机组的转子不可能有很大的外形尺寸和重量,因此,它的平衡是在轴承架上进行。但是,每个转子的磁极安装在上环箍之前,要称重和记录,然后根据使用数量相近的磁极按正负极彼此布置好,当转子任意部分质
The disturbing forces that cause the hydraulic power unit to amplify vibration are: mechanical, hydraulic, and electric. Centrifugal force caused by rotor mass during vibration occurs when the working wheels of the turbine, generator rotor and exciter rotor unbalanced. Turbine wheel should be static balance at the factory or installation. As a hydraulic turbine rotor can not have a large size and weight, so its balance is carried out in the bearing frame. However, each rotor pole installed in the hoop before the hoist, to be weighed and recorded, and then according to the use of a similar number of poles arranged in positive and negative with each other, when any part of the rotor quality
