More Information
Summary:According to one embodiment, a seal oil feeding apparatus (10) includes a hydrogen detraining tank (11), a float trap tank (12), and an air detraining tank (13). The hydrogen detraining tank (11) is configured to collect and reserve seal oil (S) that has flowed out to the inside of a housing (3) from a sealing unit (4). The float trap tank (12) is provided integrated with the hydrogen detraining tank (11) in horizontally, and is connected to the hydrogen detraining tank (11), so that the liquid level of the seal oil (S) becomes substantially the same as the height of the hydrogen detraining tank (11). The float trap tank (12) includes a float valve (121). The air detraining tank (13) is placed at a position lower than the hydrogen detraining tank (11) and float trap tank (12), and reserves seal oil (S) that has flowed out from the float valve (121).
