电动燃油增压泵是飞机燃油系统主要附件之一,主要用来给发动机提供所需流量和压力的燃油,保证发动机初期阶段供油以及飞行过程中的辅助供油。该文对SR20型飞机常用的电动燃油增压泵进行了实物测绘并对其工作原理进行了阐述,对飞机维护人员和部件修理人员了解该型增压泵的工作原理具有一定的参考意义。
Electric fuel booster pump is one of the main components of the aircraft fuel system, mainly used to provide the engine with the required flow and pressure of fuel, to ensure the initial stage of the engine oil supply and auxiliary fuel during flight. This paper makes a physical survey of the electric fuel booster pump commonly used in the SR20 aircraft and describes its working principle. It is of some reference significance for the maintenance personnel and the repair personnel of the aircraft to know the working principle of the booster pump.
