Abstract

The oil-gas separator comprises a separation cavity barrel, an oil-gas mixture inlet section and an oil storage cavity, the oil-gas mixture inlet section and the oil storage cavity are connected to the two ends of the separation cavity barrel, an exhaust pipe is further connected to the oil-gas mixture inlet section, and the oil-gas mixture inlet section comprises a pre-swirling flow channel and an inlet flow channel communicated with the pre-swirling flow channel; the pre-swirling flow channel is in a cylinder shape on the whole, an inlet flow channel is arranged in the tangential direction, and the outer side wall of the pre-swirling flow channel is in an Archimedes spiral line shape. According to the dynamic pressure type oil-gas separator, the Archimedes spiral is introduced into the dynamic pressure type oil-gas separator of the aero-engine lubricating oil system, the pre-rotation section above the oil-gas separator is arranged to be of the Archimedes spiral type, and it is guaranteed that the flow of oil-gas mixtures entering all branches is roughly the same; the stability of a flow field in the separator is improved, the lubricating oil amount of a central backflow area of the separator is reduced, and the separation efficiency of the separator is improved.

Description

technical field [0001] The invention relates to the technical field of aero-engine lubricating oil systems, in particular to an oil-gas separator with a helical inlet channel. Background technique [0002] Aeroengines contain a variety of high-speed rotating components, among which high-speed rotating friction components such as bearings and gears bear huge loads. The aero-engine lubricating oil system continuously supplies lubricating oil to these high-speed rotating parts to achieve lubrication and cooling of the frictional contact area, and maintain these parts to work efficiently and continuously. Aeroengine lubricating oil system is mainly composed of fuel tank, fuel supply pump, oil filter, oil return pump, ventilator, oil and gas separator, radiator and other components. Since the lubricating oil system contains a certain amount of air, the lubricating oil in the system will be continuously mixed with the air during the normal operation of the aero-engine to form an ...
