Description
Technical Field

With the increasing popularization of important mechanical equipment such as air-space transport tools, high-speed trains, large ships, high-speed continuous rolling and continuous casting machines and the like, the demand for detecting the running conditions of the large ships and the high-speed continuous rolling and continuous casting machines has rapidly increased, and a detection device widely applied at home and abroad is a ferrograph analyzer at present. SH/T0573-93 analytical iron spectrometry (analytical iron spectrometry) in-use lubricating oil wear particle test has clear requirements for the examination of in-use lubricating oil wear particles by an iron spectrum analyzer. Prepared lubricating oil samples are flowed onto a substrate through a peristaltic pump, various abrasive particles in oil are separated by a magnetic field and deposited on the substrate, and then the shape, the size and the coverage area of the wear particles are observed and measured under a ferrographic microscope to analyze the wear condition of the machine. However, in the current use, the existing iron spectrum analyzer is offline detection, equipment needs to be shut down when an oil sample is taken, a large amount of waste of production resources is caused, spectrum slices need to be manufactured manually, the requirement on the working experience of an operator is high, the subjective components are many, and the manufacturing efficiency of the spectrum slices is low.
Chinese patent CN102494973B discloses an online full-flow visible ferrograph, which comprises a lubricating oil path ferromagnetic abrasive grain collector, a collector cleaning mechanism and a full-angle scanning visible device, wherein lubricating oil enters the ferromagnetic abrasive grain collector from an oil inlet, ferromagnetic abrasive grains in the lubricating oil deposit in an observation area of the ferromagnetic abrasive grain collector under the action of a static magnetic field, an industrial camera observes the characteristics of the abrasive grains and takes images through the mechanism action at the full angle, when the collector cleaning mechanism is powered on, the static magnetic field of the observation area of the ferromagnetic abrasive grain collector disappears, and the abrasive grains deposited in the observation area are flushed clean by oil flow so as to be monitored next time. However, the scheme deposits all sizes and types of ferromagnetic abrasive particles simultaneously without dilution, which causes the stacking of the abrasive particles, and cannot accurately read the size distribution and the shape of the abrasive particles required by SH/T0573-93, so that the components and the types of the abrasive particles cannot be determined. In addition, the scheme is only suitable for detecting the abrasive particles of the lubricating oil circuit, cannot bear high pressure in structural design and does not have universality.

However, this system cannot identify the change in the color of the abrasive grains caused by high temperature at the time of severe sliding wear.
