Abstract

The invention discloses an axis vent pipe structure of a turbine engine and the turbine engine. The axis vent pipe structure comprises an axis vent pipe, a wind wheel assembly and an oil outlet structure, the axis vent pipe comprises a main pipe section, a wind wheel assembly installation pipe section and a back hollow baffle with a first through hole, the wind wheel assembly installation pipe section is arranged on the front side of the main pipe section in the axial direction of the axis vent pipe, the back hollow baffle is located between the wind wheel assembly installation pipe section and the main pipe section, and the wind wheel assembly installation pipe section and the main pipe section are communicated through the first through hole; the wind wheel assembly comprises an impeller which is arranged in the wind wheel assembly installation pipe section and can conduct centrifugal separation on oil drops in oil-gas mixing air flow entering the axis vent pipe, and the back hollow baffle prevents the oil drops obtained through centrifugal separation from entering the main pipe section; and the oil outlet structure comprises an oil outlet for guiding the oil drops obtained through centrifugal separation out of the axis vent pipe. According to the technical scheme, the lubricating oil consumption amount of the turbine engine can be reduced, and the maintaining cost can be reduced.

Description

technical field [0001] The invention relates to the field of engines, in particular to an axial ventilation pipe structure of a turbine engine and the turbine engine. Background technique [0002] The lubricating oil system of a turbine engine used as an aeroengine is mainly used to lubricate and cool the bearings of the engine. During normal operation of the engine, the sealing air used to seal the bearing cavity flows from the bearing cavity to the shaft vent tube. In the prior art, the sealing air flowing out from the bearing cavity is usually an oil-air mixed flow containing a part of lubricating oil droplets. When the engine is running, the lubricating oil droplets are discharged out of the shaft center ventilation pipe together with the oil-air mixed flow. This will increase the oil consumption of the engine and increase the maintenance cost of the engine oil system. Contents of the invention [0003] The purpose of the present invention is to provide a kind of sha...
