Abstract

A device for recovering magnetic particles trapped on a magnetic plug, which includes a supporting end and a magnetized element for retaining the magnetic particles in a liquid resulting from the wear of parts with which the liquid has been in contact, the recovery device including a magnetization device and an enclosure having an opening, the enclosure to receive the magnetic plug via the opening such that the magnetized element is located inside the enclosure and the supporting end is located outside the enclosure. The opening is sized such that the supporting end blocks the opening. The device also includes an injection nozzle to inject a gaseous fluid inside the enclosure, the nozzle being oriented such that the flow of gaseous fluid expels the magnetic particles retained on the magnetized element toward the bottom of the enclosure. The magnetization device traps the particles urged toward the bottom of the enclosure.

Description

technical field [0001] The present invention relates to a device and method for recovering magnetic particles trapped on magnetic plugs, which use magnets to absorb magnetic particles produced by wear and tear of parts in liquids, such as those placed in equipment casings or aircraft Rotating parts inside the engine. Background technique [0002] The magnetic plug is placed in a known manner in a fluid line (usually oil, cooling fluid or fuel oil) in a housing containing moving parts such as gears or bearings in said fluid. [0003] Generally speaking, the function of the fluid lines is to enable the lubrication and / or cooling of moving parts, usually rotating parts. It turns out that a moving part has friction over its entire service life - for example - due to contact between two gears or bearings, more precisely, wear due to impacts or strong friction between rotating parts, The impact or strong friction is due to strong and abnormal vibrations in the housing. Whatever...
