Problems solved by technology

[0005] In the above three patents, the oil flows along the direction perpendicular to the magnetic induction intensity in the working air gap. When the abrasive particles are deposited, the excitation intensity is constant. Dispersed and orderly deposition is realized according to the particle size in the direction, and multiple sensor devices are arranged in the oil flow direction to detect abrasive particles of different sizes, which requires a long length of the magnetic pole, which limits the reduction of the sensor volume
In terms of the light source for imaging, only the transmission light source mode is used, and the morphology of the abrasive grain surface cannot be reflected when the abrasive grain image is collected.

Embodiment Construction

[0018] Accompanying drawing is the specific embodiment of the present invention;

[0019] Below in conjunction with accompanying drawing, content of the present invention is described in further detail:

[0020] With reference to shown in Fig. 1, the structural principle and working principle of the device of the present invention are: the present invention comprises computer 1, D / A card 2, power amplifier 3 and oil pump 4, and computer 1 controls the output of power amplifier 3 by D / A card 2, power amplifier 3 is connected to the ferrographic sensor 5 to control the excitation and light source. At the same time, the computer 1 is connected to the oil pump 4 through the D / A card 2 and the power amplifier 3 to control the flow of the oil pump 4. In this way, under the control of the computer 1, by adjusting the strength of the working magnetic field and the flow rate of the oil, the separate deposition of large and small abrasive particles in the same area can be realized, inst...

Description

technical field [0001] The invention relates to a device and method for monitoring equipment wear particles, in particular to a short deposition distance image-type online ferrography device and method. Background technique [0002] The existing ferrography technology is a technology that uses high-intensity and high-gradient magnetic fields to separate ferromagnetic abrasive particles from oil, and make them deposit in an orderly manner according to their size, and then analyze and study them. Ferrography technology monitors a wide range of abrasive particle sizes. It can understand the wear mechanism and wear parts of the equipment by observing the morphology of abrasive particles, and judge the overall wear level of the machine by using the abrasive particle concentration and particle size distribution. Efficient method for periodic condition monitoring and remaining life estimation. [0003] Ferrography includes off-line ferrography and online ferrography. The offline ...
