Description

technical field

[0001] The invention belongs to the technical field of on-line monitoring devices for abrasive particles of mechanical equipment, in particular to an on-line monitoring device for ferromagnetic particles of engine oil. Background technique

[0002] Abrasion is one of the main factors of failure of mechanical parts. Among the failure modes of machine parts, wear failure mode accounts for more than 70%. The state of abrasive particles implies a large amount of information on the operating state of mechanical equipment, which can reflect the current situation and development trend of equipment wear in a timely manner. At the same time, it is also an important basis for diagnosing equipment failures, predictive maintenance, and improving design of equipment.

[0003] The detection of abrasive particles in mechanical equipment oil is generally divided into two categories: offline and online detection. Off-line detection such as: spectrum analysis, ferrography ana...
