Rotating equipment friction fault diagnosis method and system and readable storage medium

Abstract

The invention relates to a rotating equipment friction fault diagnosis method and system and a readable storage medium, and the method comprises the steps: collecting friction signals of different measurement points of equipment, and carrying out the preprocessing of the friction signals; extracting equipment friction characteristics, and establishing a friction characteristic parameter set; extracting friction fault feature parameters through a multi-feature fusion technology, and obtaining result information; performing friction fault diagnosis through the result information to obtain faultinformation; generating a diagnosis report according to the fault information, and sending the diagnosis report to the platform; and by collecting multi-point friction signals of the rotating equipment and conducting noise reduction processing on the signals, reducing the deviation of the friction signals, so that the collected data can be closer to the actual value, friction performance representation is conducted on the friction signals, a friction characteristic parameter set is constructed, performance changes in the friction process of the rotating equipment can be comprehensively reflected, and fault diagnosis is more accurate.

Description

technical field [0001] The invention relates to a friction fault diagnosis method, in particular to a friction fault diagnosis method, system and readable storage medium of rotating equipment. Background technique [0002] Fault diagnosis refers to the technology of judging whether the equipment is running normally or not, and judging the cause and location of the failure, as well as the preset equipment failure state, according to various information generated during the operation of mechanical equipment in a certain working environment. Rotating equipment fault diagnosis, in terms of the characterization of the friction performance of rotating equipment, is only used for traditional performance indicators such as friction coefficient and wear amount, and uses a simple calculation method of average or maximum value, ignoring the dynamics of friction performance parameters during the operation of rotating equipment. Changes make the friction performance characterization not ...
