OIL TANK OF STEAM TURBINE Russian patent published in 1999 - IPC

FIELD: steam turbines, applicable for supply of oil to steam turbine. SUBSTANCE: oil tank has a body with oil inlet and outlet branch pipes, and an impurities drain branch pipe. Inside the body provision is made for a device for separation of air from oil in the form of a packet of inclined corrugated partitions with air traps and mud collectors. Besides, the tank is furnished with arrangements for outlet of drops of water and heavy fractions of impurities to the drain branch pipe. In this oil tank, as compared with the known designs, a more profound cleaning of used oil is carried out not only of air and impurities, but also of water. EFFECT: absence of jets of oil flow and due to it increased gravitational effect of cleaning; reduced surface of contact of impurities with oil, which slows downs the processes of ageing of the latter and increases its (oil) service life. 2 cl, 1 dwg
