A preparation device and preparation method of ferrographic flexible spectrum based on spraying method

Abstract

The invention discloses a preparation device and method for ferrographic flexible spectrograms based on a spraying method. The preparation device includes a substrate, a spray pipe and a stirring device; the substrate is located below the spray pipe and arranged horizontally; the spray pipe Vertically arranged along the longitudinal direction; the periphery of the injection pipe is equipped with a magnetic field, and the magnetic field is configured to make the upper section, middle section and lower section of the injection pipe from top to bottom have different magnetic field strengths; the stirring device is arranged on the Above the injection pipe, it is used to stir and drive the oil loaded in the injection pipe so as to realize the suspension of abrasive particles in the oil by mechanical stirring; the base and the injector are configured to be able to move relative to each other along at least one moving direction . The invention uses a magnetic field to stratify the abrasive grains in the oil, and sprays the abrasive grains onto the heat-sensitive adhesive for curing and bonding. The dispersion of the abrasive grains is good, the recovery rate of the abrasive grains is high, and the adhesion effect of the abrasive grains is good. Can be stored for a long time.

Description

technical field [0001] The invention relates to the field of equipment oil monitoring, in particular to a preparation device and method for ferrographic flexible spectrograms based on a spraying method. Background technique [0002] At present, the ferrographic analysis technology for the collection and analysis of wear and abrasive particles in the friction pair of equipment is widely used in the field of equipment oil monitoring, and is one of the core technical components of oil monitoring technology. In mining, engineering machinery, steel, petrochemical, electric power, port, metallurgy, shipbuilding, military and other fields involving large machinery and equipment, ferrography technology is used to monitor the friction, wear and lubrication conditions of friction pairs of equipment, and to detect faults. Forecasting and forecasting have become important technical means for equipment and equipment status monitoring. At present, ferrography technology can be divided in...
