摘　　要：在水轮发电机组中,轴承受摩擦作用影响产生大量的摩擦热,摩擦热使油槽中润滑油温度升高,随着机组转动油槽中会产生大量气液混合态的油雾。为防止油雾溢出,通常在油槽中选用带有气密封功能的油挡装置。对气密封油挡装置在抑制油槽油雾溢出方面的作用效果进行仿真分析,并建立测试平台,对某水轮发电机组气密封油挡作用下的油槽结构件内气体压力进行测试,将仿真分析结论与实测情况进行对比。结果表明,气密封油挡装置在抑制油槽油雾溢出方面具有明显作用效果,是一种值得推广的水轮发电机组防油雾措施。It generates a large amount of friction heat on the surface of bearings in hydrogenerator units.The friction heat can make the oil temperature rise and may generate a large amount of oil mist.In order to prevent oil leakage,it trend to use an air seal oil baffle device in a hydrogenenrator.The effectiveness of the gas sealed oil baffle device in suppressing oil mist overflow from the oil tank is simulated and analysed,and a testing platform is established to test the gas pressure inside the oil tank structure under the action of the gas sealed oil baffle in a certain hydrogenerator.The simulation analysis is compared with the measured results,indicating that the gas sealed oil baffle device has a significant effect in suppressing oil mist overflow in a hydrogenerator and it is worth promoting.
