Description

Technical Field

[0001] The invention relates to the technical field of non-destructive electromagnetic detection, and more particularly to an electromagnetic detection technology for oil metal particles of large mechanical moving parts, and more particularly to a push-back type oil non-destructive electromagnetic detection method and device thereof. Background Art

[0002] As the "heart" of aircraft, aircraft engines require regular safety inspections and maintenance. The detection of metal particles in oil is a safety inspection technology mainly used for large and major mechanical moving parts such as aircraft engines. The detection of metal particles in oil is mainly divided into airborne type (i.e. monitoring when the engine is in working state) and non-airborne type (extracting a certain amount of oil for inspection and analysis when the engine is stopped on the ground).

[0003] Airborne oil metal particle detection can install the instrument in the oil pipeline of aircraft engines, etc., and transmit the data to the analysis display after real-time monitoring. Non-airborne oil metal particle detection requires manual extraction of oil for detailed detection and analysis, with many detection parameters and high accuracy requirements, and relatively low work efficiency, which consumes manual time. The present invention is an improvement on the method and equipment for non-airborne oil metal particle detection.
