Title:
HIGH-ROTATION-SPEED OIL-GAS SEPARATOR FOR TURBINE ENGINE
Document Type and Number:
WIPO Patent Application WO/2022/100150
Kind Code:
A1
Abstract:
A high-rotation-speed oil-gas separator for a turbine engine, the oil-gas separator comprising a hollow rotating shaft (77), wherein the upper portion of the rotating shaft (77) is provided with an oil input cavity assembly; the upper middle portion of the rotating shaft (77) is provided with a separation cavity assembly; and the lower portion of the rotating shaft (77) is provided with a driving mechanism. The separation cavity assembly comprises: a separator cavity (12) located on the periphery of the upper middle portion of the rotating shaft (77); a partition layer, which is located in the middle portion of the rotating shaft (77) in the separator cavity (12); a first centrifugal disc (19) located on the upper portion of the partition layer; a second centrifugal disc (20) located on the lower portion of the partition layer; a plurality of first through holes (21) located on the periphery of the first centrifugal disc (19); a plurality of second through holes (22) located on the periphery of the second centrifugal disc (20); an oil guide groove (17) that is located in the separator cavity (12) and is in communication with the plurality of first through holes (21); and an oil outlet (12a) that is located in the separator cavity (12) and is in communication with the oil guide groove (17). A gas outlet (7a) is provided at the bottom portion of the rotating shaft (77). The high-rotation-speed oil-gas separator is self-powered for driving, is not affected by the working condition of an engine, has high separation efficiency and can satisfy the volume and weight of a high-rotation-speed turbine engine.
