PROBLEM TO BE SOLVED: To provide a seal oil device of a dynamo-electric machine capable of suppressing vibration of a rotary shaft, by controlling the supply pressure of the seal oil in each shaft seal portion appropriately.SOLUTION: A seal oil device 9 includes a seal oil supply device 6 for supplying seal oil 7, a first line 10a for leading the seal oil 7 from the seal oil supply device 6 to one shaft seal portion 5a, and a second line 10b for leading the seal oil 7 from the seal oil supply device 6 to the other shaft seal portion 5b. The first line 10a is provided with a first pressure regulation valve 24a, and the second line 10b is provided with a second pressure regulation valve 24b. The first pressure regulation valve 24a regulates the pressure of the seal oil 7 passing through the first pressure regulation valve 24a, and the second pressure regulation valve 24b regulates the pressure of the seal oil 7 passing through the second pressure regulation valve 24b.SELECTED DRAWING: Figure 1 |
