Abstract

The invention relates to the technical field of turbine engines, in particular to a hot end fuel and lubricating oil pipeline structure of a turbine engine, and aims to solve the problems that in theprior art, the heat efficiency of the engine cannot be better improved and a better cooling effect on a bearing cannot be achieved. The hot end fuel and lubricating oil pipeline structure comprises alubricating oil return cavity shell, a fuel oil preheating cavity shell, a fuel oil preheating cavity, a fuel oil inlet pipe, a lubricating oil return pipe and a lubricating oil inlet pipe, wherein the fuel oil inlet pipe, the lubricating oil return pipe and the lubricating oil inlet pipe are sequentially nested from outside to inside and are reserved with gaps among one another; one end of the fuel oil inlet pipe sequentially communicates with the fuel oil preheating cavity and a fuel oil supply pipe; one end of the lubricating oil return pipe communicates with the inside of the lubricating oil return cavity shell; and one end of the lubricating oil inlet pipe is positioned inside the lubricating oil return cavity shell and is opposite to the upper part of the bearing. According to the hot end fuel and lubricating oil pipeline structure, the fuel oil inlet pipe, the lubricating oil return pipe and the lubricating oil inlet pipe are sequentially nested from outside to inside, and the temperatures of the fluids in the three pipelines are sequentially reduced from outside to inside, so that the cooling effect on the bearing is improved and the heat efficiency of the engine is improved.

Description

technical field [0001] The invention relates to the technical field of turbine engines, and more particularly relates to a structure of a hot end combustion lubricating oil pipeline of a turbine engine. Background technique [0002] The bearings at the turbine end of the engine need to be cooled and lubricated by spraying lubricating oil. After the lubricating oil enters the bearing, it must pass through the high-temperature area of ​​the engine. On the one hand, when the lubricating oil flows through this area, it will exchange heat with the environment to increase the temperature of the lubricating oil sprayed on the bearing, thereby reducing the lubricating oil. The temperature difference between the oil and the bearing makes the cooling effect worse and the working temperature of the bearing rises. On the other hand, the temperature of the lubricating oil close to the wall of the oil supply pipeline is high, which is prone to coking of the lubricating oil, and the cokin...
