Problems solved by technology

[0002] The lubricating oil of the 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 the magnetic metal chips in the oil. It can only be inspected regularly or decomposed. Check during the inspection, unable to alarm the metal shavings online

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. like 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 external...

Abstract

The invention relates to the field of aero-engines, in particular to an aero-engine lubricating oil monitoring structure and method. The structure includes a housing, an insulating sleeve, a fusible sheet, a gasket, a sealing ring, an insulating bush, a stop ring, an electrode, a magnet, and an outer bushing. Pin 3 of the cable plug is connected to the magnet, and the cable plug The No. 2 pin in the outer bushing is connected to the outer bushing, the magnet is fixed in the outer bushing, the outer bushing and insulating sleeve connected to each other are connected to the shell, and the fusible sheet is installed inside the outer bushing and outside the magnet in sequence from inside to outside , Gasket, sealing ring, insulating bushing and electrode, fusible sheet, gasket, sealing ring, insulating bushing and electrode are fixed by the stop ring in the electrode collar groove. The invention realizes the simultaneous monitoring of the magnetic metal shavings in the oil and the temperature of the oil by setting the magnetic poles and the fusible sheet, and can be overlapped with an online detection system, and can be applied to the monitoring of lubricating oil at key parts of various types of engines.

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...
