Embodiment Construction

[0021] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0022] Such as figure 1 , 2 As shown, this embodiment provides a fiber grating-based oil pipeline oil leakage detection system, including a detection sensor, a multi-channel wavelength demodulator and a computer. The detection sensor is composed of a base material, a sensitive material, and a fiber grating. The above-mentioned sensitive material is composed of EPDM rubber that swells when encountering oil, and is in the shape of a long strip. The expansion of the rubber, the base material is made of EPDM rubber in a long strip shape, and the surface of the base material is covered with a layer of epoxy resin to isolate the contact with the oil. The optical fiber passes through the sensitive material and the base material, and two gratings with different wavelengths are respectively set in the middle of the sensitive material ...

Abstract

The invention relates to the aviation pipeline oil leakage detection technical field, and provides an oil transfer pipeline oil leakage detection system based on fiber grating and a work method thereof; the detection system comprises a detection sensor, a multi-channel wavelength demodulator and a computer; the detection sensor comprises a substrate material, a sensitive material, and the fiber grating; the fiber penetrates the sensitive material and the substrate material; two rasters of different wavelengths are arranged between the sensitive material and the substrate material; the raster in the sensitive material is a detection raster; the raster in the substrate material is a reference raster; the reference raster and the detection raster are symmetrically arranged in the joint of anairplane conduit. The detection system can fully monitor the oil leak conditions of airplane fuel oil, lubricating oil and hydraulic oil system pipelines, thus providing timely and accurate information for daily maintenance and air dangerous case treatments, and ensuring flight safety.

Description

technical field [0001] The invention relates to the technical field of aviation pipeline oil leakage detection, in particular to a fiber grating-based oil pipeline oil leakage detection system and a working method thereof. Background technique [0002] Leak detection of aircraft piping systems is a difficult and complex task in the aircraft inspection process. There are many systems on the aircraft, and the airtightness of all systems on the aircraft must be ensured to ensure that the aircraft can fly safely. The aviation pipeline system is mainly composed of hydraulic system, fuel system and lubricating oil system. The working environment and working status of each system are different. At present, there is a lack of a special method for detecting oil leakage in aviation pipelines. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art and provide a fiber grating-based oil pipeline oil leak...
