Fuel oil system for gas turbine starter

Abstract

The invention discloses a fuel oil system for a gas turbine starter. The fuel oil system comprises an oil tank, an oil delivery pump, a filter and an oil nozzle; the right side of the oil tank communicates with a cooling mechanism through an oil return pipe, and the right side of the cooling mechanism communicates with a filter mechanism through a discharging pipe; the filter mechanism comprises a filter box, and the bottom of the inner wall of the filter box is fixedly connected with a frame body; and the top of the inner wall of the frame body is fixedly connected with a rectangular frame. The invention relates to the technical field of aviation starters. According to the fuel oil system for the gas turbine starter, the cooling mechanism comprises a shell, fuel oil enters a cooling box through the oil return pipeline after being filtered, heat in the fuel oil is conducted out of the cooling box through a heat conduction plate and cooling fins, meanwhile, a water pump conveys cooling water into a cooling coil pipe, and the cooling coil pipe further cools the fuel oil in the cooling box, so that the temperature instability of the oil tank and the generation of a large amount of foam in oil storage caused by over-high temperature during fuel oil return are prevented.

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 term. 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
