    • PROBLEM TO BE SOLVED: To provide a sealing oil supply device of a rotary electric machine, in which separability of oil and water is improved.SOLUTION: A sealing oil supply device of a rotary electric machine includes: a vacuum chamber 5 that supplies a sealing oil to a shaft sealing unit (a sealer 3) of a rotary electric machine 1, in which a hydrogen gas is sealed, and recovers the sealing oil passed through the shaft sealing unit for vacuum degassing; and an oil separator 14 that takes in an exhaust gas exhausted from the vacuum chamber 5 via a vacuum pump 12 to separate oil and water from the exhaust gas. The oil separator 14 includes an introduction pipe 13 for the exhaust gas arranged to protrude from a bottom face to a predetermined height, and a guide pipe 20 having an inclined face 20a opening upward in a funnel shape. The oil and the water separated from the exhaust gas accumulate in a bottom portion of the oil separator 14 through the guide pipe 20, so that the oil is supplied to the vacuum pump 12 from a feed pipe 19 in a side face of the oil separator 14, and the water is exhausted to the outside through a water gage 17 connected to the bottom face.
    • 要解决的问题:提供一种旋转电机的密封供油装置,其中改善了油和水的分离性。 解决方案:旋转电机的密封供油装置包括:真空室5,其将密封油供应到旋转电机1的轴密封单元(密封件3),其中氢气被密封 并回收通过轴密封单元的密封油进行真空脱气; 以及油分离器14,其经由真空泵12吸入从真空室5排出的废气,以将油和水与废气分离。 油分离器14包括从底面突出到预定高度的用于排气的引入管13和具有以漏斗形状向上开口的倾斜面20a的引导管20。 与废气分离的油和水通过导管20积聚在分油器14的底部,从而从油分离器的侧面的供给管19向真空泵12供给油 14,并且通过连接到底面的水表17将水排出到外部。 版权所有(C)2013,JPO&INPIT
