Abstract
This oil console device (24) is provided with: an oil tank (40) which recovers and stores lubricating oil which has lubricated a bearing portion supporting a rotating body; a pressure reducing fan (71) which is coupled to the oil tank (40) and which reduces the pressure inside the oil tank (40) such that the pressure becomes a negative pressure; an oil mist separator (50) which is provided on the oil tank (40) side of the pressure reducing fan (71) and which captures lubricating oil that has become a mist; and, on the downstream side of the pressure reducing fan (71), a exhaust unit (63s) which vents gas in the oil tank (40) to the outside.
Claims5
An oil console device, comprising:
- an oil tank which includes a receiving portion which receives lubricating oil which has lubricated a bearing portion supporting a rotating body and a separation gas supplied to the bearing portion, and stores the lubricating oil which is recovered through the receiving portion;
- a pressure reducing fan which is connected to the oil tank and reduces a pressure inside the oil tank such that the pressure becomes a negative pressure;
- an oil mist separator which is provided to be closer to the oil tank side than the pressure reducing fan and captures the misted lubricating oil;
- an oil transfer pump which transfers the lubricating oil stored in the oil tank;
- an exhaust unit which discharges gas inside the oil tank to the outside on a downstream side of the pressure reducing fan;
- a plurality of the pressure reducing fans;
- an exhaust switching portion which switches a discharge destination of the gas inside the oil tank to any one of the plurality of pressure reducing fans;
- and
- a tank pressure detection section which detects a pressure inside the oil tank;
- wherein in a case where a pressure inside the oil tank detected by the tank pressure detection section exceeds a predetermined threshold value, the exhaust switching portion switches the discharge destination of the gas coming from inside the oil tank.
