Problems solved by technology

[0003] Of course, it is also possible to add a separate temperature sensor. However, this will not only increase the hardware complexity of the detection sensor, but also cause too much space for detection. It is more complicated, resulting in an increase in data transmission and software functions

Embodiment Construction

[0032] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0033] Such as figure 1 As shown, an online oil electromagnetic detection method that simultaneously acquires temperature information is used for the extraction of temperature information in the evaluation, monitoring and detection of various parameters of oil abrasive particles in service pipelines such as aircraft engines, including calibration value detection and online The two parts of monitoring and detection are characterized in that the phase angle change value on the planar impedance diagram of the eddy current detection coil detection signal is used to analyze and extract the temperature signal value. The specific method steps are as follows:

[0034] a. Temperature calibration value extraction: extract the impedance phase angle signal value of the eddy current detection signal at room temperature, and store it as a calibration value ...

Abstract

The invention relates to an on-line oil electromagnetic detection method and device capable of simultaneously acquiring temperature information, and is used for extracting temperature information in evaluation, monitoring and detection of various parameters of oil abrasive particles (11) of an in-service pipeline (1) of an aircraft engine and the like. The device comprises a flexible belt (2) annularly wound on an oil pipeline and array type eddy current detection sensors (21) arranged on the flexible belt, and is characterized in that the array type eddy current detection sensors (21) are arranged to be identical pairwise overlapped coils in pairs, and differential type eddy current detection sensor coils (211 and 212) in array distribution are formed. The temperature information of the oil can be detected without adding a temperature sensor in the oil detection of the in-service pipeline.

Description

technical field [0001] The invention relates to the technical field of non-destructive testing, in particular to the eddy current detection technology of online pipeline oil particles, and in particular to an online oil electromagnetic detection method and a device thereof for simultaneously obtaining temperature information. Background technique [0002] In the electromagnetic detection of in-service oil, the parameters such as the number and size of ferromagnetic abrasive particles in lubricating oil such as aircraft engines are mainly detected and evaluated, so as to further evaluate the life and damage of the engine. Under normal circumstances, the temperature parameters of the oil are seldom tested. However, if the oil temperature is too high, it means that the lubrication system is faulty and needs to be repaired. If the oil temperature is too high, the lubricating oil will become thinner, and the oil film on each friction surface will be difficult to form. It will for...
