Abstract

PROBLEM TO BE SOLVED: To easily add a lubricating oil without depending on a head by using the pressure difference between the inlet side and outlet side of an oil separating tank installed at an outlet of a screw turbine. SOLUTION: An oil service tank 18 for make-up-feeding oil to an oil tank 14 is connected to the oil tank 14 and leads in the inlet side pressure of an oil separating tank 12 through a pressure piping 20. As a result, the inlet side pressure P1 of the oil separating tank 12 acts upon the oil level in the oil service tank 18. The pressure of the oil tank 14 is equal to the outlet side pressure P2 of the oil separating tank 12. A pressure difference P1>P2 is therefore generated across the oil separating tank 12, and the lubricating oil can be smoothly added to the oil tank 14 from the oil service tank 18 by this pressure difference P1>P2.

The lubricating screw turbine supplies lubricating oil directly to the working medium, and an oil separation tank is provided with an oil separating tank for separating the lubricating oil supplied from the working medium vapor. In the oil separation tank, a pressure loss occurs when the lubricating oil is separated from the working medium vapor. The oil tank has the same pressure as the oil separation tank outlet to receive the collected lubricating oil. Therefore, if the oil service tank is pressurized with the working medium vapor at the inlet of the oil separation tank, lubricating oil can be added smoothly due to the pressure difference between the inlet side and the outlet side of the oil separation tank.
