据苏联《水工建设》杂志报道,在苏联水电站机组机械设备故障中,有60%出自推力轴承。随着现代水轮发电机组单机容量的增大,保证机组可靠性问题变得特别重要,因而对推力轴承的要求也越来越高。近年来,苏联在水电站机组推力轴承研究改造方面取得了显著成效,从而提高了机组的安全可靠性。 According to the Soviet Union, “Hydraulic Construction” magazine reported that in the Soviet hydropower plant mechanical equipment failure, 60% from thrust bearings. With the increase of stand-alone capacity of modern hydro-generating units, the reliability of the units has become particularly important, and the requirements for thrust bearings are also getting higher and higher. In recent years, the Soviet Union has made remarkable achievements in the research and reconstruction of thrust bearing units of hydropower units, thereby improving the safety and reliability of the generating units.
