最近进行的水电故障调查结果表明,轴承方面占60%—80%。主要症状是轴颈磨损严重,甚至薄弱;瓦温过高,甚至烧损;轴承进水,使油乳化变质等。轴承是旋转机械的枢纽部件,非常关键。转桨式水电机组,除了主轴承、推力轴承、导轴承以外、转轮叶片、活动导叶、接力器及其拉杆,控制环及其拐臂以及阀门等,也都设有轴承,用量较多,而且容易磨损,故障率高。涉及轴承故障的原因,多种多样。 Recent hydropower fault survey results show that the bearings account for 60% -80%. The main symptoms are severe neck wear, or even weak; high temperature and even burn; bearing water, oil emulsion deterioration. Bearings are pivot parts of rotating machinery, the key. In addition to the main bearing, thrust bearing and guide bearing, rotor blades, movable guide vanes, relay and its pull rod, control ring and its crank arm and valves, etc., are also equipped with the bearings, the amount of more , But also easy to wear, high failure rate. There are many reasons involved in bearing failure.
