一、轴承甩油的情况立式水轮发电机组轴承油槽的挡油结构,过去往往被人们忽视,轴承甩油问题是电厂运行检修中较难解决的问题之一。由于主轴旋转,轴颈线速度较大,形成甩油,油槽油雾四处飞溅,油雾随发电机冷热风的交换进入发电机。时间一长,发电机线圈上会附上一层油污,发电机绝缘易劣化。甩油较大者,水轮机机坑油雾茫茫,水轮机 First, the situation bearing oil thrown Vertical hydro-generator bearing oil tank of the oil structure, the past is often overlooked, bearing oil rejection problem is one of the more difficult to solve in the operation and maintenance of power plants. As the spindle rotation, journal line speed larger, the formation of oil thrown, oil splashes around the oil mist, oil mist with the cold exchange of hot and cold wind into the generator. Over time, the generator coil will attach a layer of oil, the generator insulation is easy to deteriorate. Larger oil throw, water turbine pit fog, turbine
