Abstract

The invention discloses a rotary machine vibration diagnosis method and system based on a vibration sensor, electronic equipment and a storage medium, and the method comprises the steps: adding at least one measurement definition for each measurement device, then creating roller bearing parameter maintenance information, binding the sensor to a measured device as a measurement point, and carrying out the measurement of the roller bearing parameter maintenance information; and associating the measuring points with the roller bearing parameter maintenance information, and analyzing the number of the measuring points to obtain a diagnosis result. According to the method, the measuring point data and the characteristic value data can be acquired by using the sensor, the corresponding attached drawings are drawn, and fault diagnosis is performed on the equipment according to the vibration condition of the rotating machine according to the calculation result of the data, so that the efficiency of pre-judging the mechanical vibration fault by a technician is greatly improved, and the loss caused by the vibration fault is prevented.

Description
