Sliding bearing vibration fault diagnosis


The vibration-related factors of the sliding bearing itself are mainly the gap vibration, the thermal imbalance caused by the collision of high-parameter equipment and the instability caused by the oil film. Other vibrations are almost the response of the excitation of the rotor system on the bearing housing. Refer to other mechanical fault diagnosis methods in the platform. As for the failure of tires, cracks and low-standard ordinary equipment, the vibration reaction is not sensitive, and oil analysis can often achieve better results.
