In addition, the lubricating system can also provide lubricating oil for a fuel booster pump and a motor in the fuel system.
As an important working system of an aircraft engine, a lubricating oil system has an important influence on the safety and reliability of the engine. By monitoring and trend analyzing the lubricating oil system, the internal fault of the engine can be found in advance, and a powerful basis is provided for predicting the service life and the reliability of engine components.
The trend analysis of a traditional lubricating oil system is mainly realized through a lubricating oil metal chip annunciator and lubricating oil spectral analysis, when an engine works, parts which move relatively in the engine can generate a large amount of metal chips, and the metal chips and the lubricating oil are mixed together to participate in the circulation of the lubricating oil. Wherein bigger particles can be intercepted by the metal chip annunciator, but a small part of fine particles are only intercepted by the metal chip annunciator, most of the fine particles still exist in the lubricating oil, and bigger errors often exist when the metal chip annunciator is adopted to judge the wear speed of the engine and carry out trend analysis of the lubricating oil.
With the advance of technology, the oil on-line chip monitor is produced. The lubricating oil on-line chip monitor is mainly manufactured on the basis of an electromagnetic induction principle, and the lubricating oil on-line chip monitor is installed in a pipeline of an aircraft engine lubricating oil system, so that the information such as the particle size, the size distribution, the quality and the like of metal chips in a lubricating oil pipeline can be detected in real time on line.

2) The other type is a fixed drawing method, namely, particles with a certain size are fixed on specific plastic equipment, and the method is used for inspection in a drawing mode, and the method is simple in equipment, low in cost and high in efficiency, but cannot detect metal particles with various sizes simultaneously, and meanwhile, the drawing speed is difficult to guarantee, and the detection error is large.
