Abstract

PURPOSE: To prevent deterioration of a lubricant and secure always the most suitable lubrication film for a bearing by controlling extraction of a working fluid in accordance with the change in the specific gravity of the lubricant in a lubricant system provided with a gas extraction means which is capable of extracting the working fluid such as freon gas mixed in the lubricant.
CONSTITUTION: A lubricant is supplied to each of the bearings for a turbine from a lubricant tank 1 to a pump 4 through a cooling device 6, and it returned to the tank 1 again. At this time, if the turbine is a freon oil turbine, the freon mixes in the lubricant. The lubricant in which freon is mixed is led to a heater 3 by a pump 2, and the temperature of the lubricant is raised by the freon vapor and the freon vapor is extracted in a gas extraction tank. The opening of a feon vapor flow regulating valve 15 is controlled by a specific gravity detecting means which outputs control signal through a temperature comprensating, specific gravity calculating circuit in response to shielding between a light source 10 and photo-bridge 11 by a buoy 9 provided in a measuring tank 8.
