Abstract

The invention discloses a high-rotating-speed oil-gas separator for a turbine engine, and particularly relates to the field of high-rotating-speed oil-gas separators. The high-rotating-speed oil-gas separator aims to overcome the defects that in the prior art, the influence of the working condition of an engine is large, and the structural size cannot meet the requirements of the high-rotating-speed turbine engine. The high-rotating-speed oil-gas separator comprises a hollow rotating shaft, an oil inlet cavity assembly is arranged on the upper portion of the rotating shaft, a separation cavityassembly is arranged in the middle of the rotating shaft, and a driving mechanism is arranged on the lower portion of the rotating shaft; and the separation cavity assembly comprises a separator cavity, a partition layer, a first centrifugal disc, a second centrifugal disc, a second oil guide groove and an oil outlet, wherein the partition layer is located in the separator cavity and located in the middle of the rotating shaft, the first centrifugal disc is located on the upper portion of the partition layer, the second centrifugal disc is located on the lower portion of the partition layer,the second oil guide groove is located in the separator cavity and communicates with a plurality of first through holes, and the oil outlet is located in the separator cavity and communicates with thesecond oil guide groove. The high-rotating-speed oil-gas separator is driven by power, is not affected by the working condition of the engine, is high in separation efficiency and can meet the requirements of the size and the weight of the high-rotating-speed turbine engine.

Description

technical field [0001] A high-speed oil-gas separator for a turbine engine, the invention belongs to the technical field of oil-gas separation, and specifically relates to the technical field of high-speed oil-gas separators. Background technique [0002] When the aero-engine is working, clean, low-temperature lubricating oil is transported to the rotating parts of the engine, thereby reducing friction and taking away the heat generated by friction. Under the effect of the pressure difference inside and outside the lubrication system, air will enter the system, and under the action of the high-speed rotating parts of the engine, the lubricating oil is mixed with the air to form lubricating oil emulsion and oil mist, which are transported to the oil return pump by the oil return pump. in the oil system. Moreover, in order to ensure the safe operation of the engine, the design capacity of the oil return pump is often greater than the oil supply, and it will also send a large ...
