Abstract

The invention discloses a centrifugal throwing oil atomization structure. The centrifugal throwing oil atomization structure comprises a rotating main shaft communicated with an oil tank of an engine; and the rotating main shaft is provided with a throwing oil atomizer for outwards throwing introduced fuel in an oil film state under the effect of centrifugal force to atomize the fuel. A throwing oil cavity is formed in the throwing oil atomizer; and the rotating main shaft is provided with multiple oil outlet holes for introducing the fuel in the throwing oil cavity. An annular oil outlet gap is formed in the throwing oil atomizer, and is communicated with the throwing oil cavity; and when the throwing oil atomizer rotates along with the rotating main shaft, the fuel fed in the throwing oil cavity from the oil outlet holes is outwards thrown in the oil film state from the oil outlet gap under the effect of centrifugal force after forming an oil film on the inner wall of the throwing oil cavity. The centrifugal throwing oil atomization structure is more uniform in peripheral fuel distribution, and is better in fuel atomization effect and dispersed distribution; and when the rotating speed of the main shaft is lower, the fuel atomization effect is excellent, the ignition is easy, and the combustion efficiency is high.

Description

Technical field [0001] The present invention relates to the field of gas turbine engines, in particular to a centrifugal oil throwing atomization structure. Background technique [0002] A gas turbine engine is a device that converts the chemical energy of fuel into mechanical work. In the field of gas turbine engines, the engine generally organizes the mixing and combustion of fuel and air through the combustion chamber, and the combustion products are discharged from the combustion chamber to drive the turbine to rotate and generate power output. The fuel is generally pressurized by a fuel pump and then fed into the fuel supply pipeline from the fuel tank, and then injected into the combustion chamber through the fuel supply pipeline via a fuel atomizing device such as a nozzle to complete the combustion in an oil mist state. The fuel atomization device is responsible for atomizing and dispersing fuel to facilitate the even distribution and organization of combustion of fuel i...
