Embodiment Construction

[0018] In the specific implementation process, the present invention mainly realizes the simultaneous monitoring of the metal shavings and the temperature of the lubricating oil in the lubricating oil of the aero-engine, and can perform online feedback. Such as figure 1 As shown, the aero-engine lubricating oil monitoring structure includes: housing 1, insulating sleeve 2, insulating coating 3, fusible sheet 4, gasket 5, sealing ring 6, insulating bushing 7, stop ring 8, and electrode 9 , magnet 10, outer bushing 11, etc., its main structure is:

[0019] No. 3 pin 13 in the cable plug is welded on the magnet 10 , and No. 2 pin 12 in the cable plug is welded on the outer bushing 11 . The magnet 10 is fixed in the outer bushing 11 by insulating glue, and the outer bushing 11 and the insulating sleeve 2 are bonded and connected with the casing 1 through an external thread. The insulating coating 3 is applied on the outer side of the outer bushing 11 to isolate it from the exter...

Abstract

The invention relates to the field of aircraft engines, in particular to a monitoring structure and method for aircraft engine oil. The monitoring structure comprises shells, insulating casing pipes, fusible pieces, gaskets, sealing rings, insulating linings, check rings, electrodes, a magnet and outer linings. A third pin of a cable plug is connected to the magnet, and a second pin of the cable plug is connected to the corresponding outer lining. The magnet is fixed in the outer linings. The outer linings and the insulating casing pipes which are connected with the outer linings are connected with the shells. The fusible pieces, the gaskets, the sealing rings, the insulating linings and the electrodes are installed in the outer linings and outside the magnet in sequence from inside to outside. The fusible pieces, the gaskets, the sealing rings, the insulating linings and the electrodes are fixed through the check rings in electrode clamping ring grooves. According to the monitoring structure and method for the aircraft engine oil, due to the fact that magnetic poles and the fusible pieces are arranged, the temperature of magnetic metal chips in oil liquid and the temperature of the oil liquid are monitored at the same time, and the monitoring structure can be in lap joint with an online detection system to be applied to monitoring of oil of key parts of engines of various types .

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to an aero-engine lubricating oil monitoring structure and method. Background technique [0002] The lubricating oil of an aero-engine can play the role of transferring chips. Currently, the commonly used monitoring structure is a single-function magnetic chip detector, which uses a magnetic joint to monitor magnetic metal chips in the oil. It can only be inspected regularly or decomposed. It can be viewed during the inspection, and the metal chip situation cannot be alarmed online. For the monitoring of lubricating oil temperature, temperature sensors are used to monitor the total oil return pipeline of each fulcrum. If simultaneous monitoring of temperature and swarf is desired, two devices are required. Contents of the invention [0003] The purpose of the present invention is to provide a structure and method for aero-engine lubricating oil monitoring. By setting magnetic poles a...
