LUBRICATION SYSTEM OF GAS TURBINE ENGINE ROTOR SUPPORT BEARINGS

摘要

FIELD: engines and pumps.;SUBSTANCE: system is equipped with three-pass and shut-off valves, at least two groups of pumps for evacuating the oil-air mixture from the cavity of the supports with shut-off valves at the inlet of the evacuation pumps and an intermediate oil-air manifold with additional shut-off valves. Three-pass and shut-off valves are made with electric control and are connected to the lubrication system through communication channels. The system also includes a deaerator with variable electric drive. All the electric drives of the lubrication system operate at modes specified by electric regulator.;EFFECT: fault tolerance pumps with variable electric drives of lubrication system with a number of evacuation pumps more than two when one of the pumps or their drives for both oil injection tract and tract oil-air mixture pumping mixes for the GTE.;2 cl, 1 dwg
