有些电站经过多年运行,发现水轮机的推力轴承和导轴承有甩油现象。虽然各个制造厂在结构设计中作了一些局部改进,运行单位也采用过不少措施,并收到了一定的效果。但是,为了更好地解决问题,有必要从不同甩油情况的繁多结构型式及其相应的改进措施中,找出共同的规律,进而确定一条解决甩油问题的合理途径。 After years of operation of some power plants, it is found that the thrust bearings and guide bearings of hydraulic turbines have oil slopping phenomenon. Although each manufacturer made some partial improvements in the structural design, the operating units also adopted many measures and received certain results. However, in order to solve the problem better, it is necessary to find a common law from the various structural types of oil slopping situations and their corresponding improvement measures so as to determine a reasonable solution to the oil slopping problem.
