| 摘 要： | 灯泡式水轮发电机组的轮毂油主要起到润滑和密封作用,尤其是要保证轮毂内油压高于轮毂外水压,防止流道水进入轮毂,以保证机组健康运转。但水电站常碰到轮毂供油故障或未能及时发现轮毂密封泄漏造成损失等情况,笔者对目前多数水电站采用的轮毂油箱供油方式与推荐的供油方式进行了分析比较,以供水电站相关同行进行参考。

| Abstract: | For bulb units,the hub oil is mainly for the purpose of lubrication and sealing,especially for ensuring that the oil pressure inside the hub is higher than the water pressure outside the hub,preventing the flow passage water from entering into the hub,so as to guarantee the unit in safe operation.But hydropower stations often have hub oil supply failure or loss due to leakage of hub seal.The paper analyzes and compares the oil supply mode via hub oil tank used by most of hydropower stations with the recommended oil supply mode,so as to provide reference for hydropower counterparts. |
