A fuel system for a gas turbine starter

Abstract

The invention discloses a fuel system for a gas turbine starter, which comprises a fuel tank, a fuel delivery pump, a filter and a fuel injection nozzle. The right side of the fuel tank is connected with a cooling mechanism through an oil return pipe, and the right side of the cooling mechanism A filter mechanism is connected through the discharge pipe, and the filter mechanism includes a filter box. The bottom of the inner wall of the filter box is fixedly connected with a frame, and the top of the inner wall of the frame is fixedly connected with a rectangular frame. The invention relates to the technical field of aviation starters. The fuel system used for the gas turbine starter includes the casing through the cooling mechanism. After the fuel is filtered, it enters the cooling box through the oil return pipe. The heat conduction plate and the cooling fin conduct the heat in the fuel out of the cooling box. The fuel is transported into the cooling coil, and the cooling coil further cools down the fuel in the cooling tank to prevent the temperature of the fuel tank from being too high when the fuel returns to oil, causing the temperature of the fuel tank to be unstable and generating a large amount of foam in the fuel storage.

Description

technical field [0001] The invention relates to the technical field of aviation starters, in particular to a fuel system for gas turbine starters. Background technique [0002] Gas turbine engine or gas turbine is a kind of engine that belongs to heat engine. Gas turbine can be a broad name. The basic principles are similar, including gas turbine jet engine, etc., and generally referred to as gas turbine engine, usually refers to It is used for ships (mainly military combat ships), vehicles (usually large enough to accommodate gas turbines, such as tanks, engineering vehicles, etc.), generator sets, etc., and the difference from propulsion turbine engines , because the turbine not only drives the compressor, but also drives the transmission shaft, which is then connected to the transmission system of the vehicle, the propeller of the ship or the generator, etc. The gas turbine engine is the most widely used aero engine at present, and it is the main In the foreseeable futur...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a fuel system for a gas turbine starter, which solves the problem that the fuel cannot be filtered during the oil return process, and the impurity particles carried are likely to cause blockage of the oil return pipeline, and at the same time, the impurity particles will be blocked Take it back to the fuel tank, reduce the quality of fuel, and it is not convenient to clean the pipeline and fuel tank, and the operation is cumbersome
