摘　　要：针对立式水轮发电机轴承的漏油问题,分析了产生漏油的原因;结合理论计算,在挡油筒体上加环形板,使之与轴领内壁形成圆盘摩擦泵。使筒体上沿原先的泄漏流动变为由外向内的泵送流动。实践证明,所采取的措施得当,轴承漏油问题得以圆满解决。Based on research of lube leakage of the vertical turbine principal axis, the leakage reason is analyzed. To solve the trouble, a round plate is fixed on the cylinder to check the leakage. The round plate and the wall of the bearing constitute a disk friction pump, which changes the leakage flow to the suction flow. It indicates that the method used here is practical, and the trouble of leakage is well resolved.
