1. Inspection of high temperature bearing vibration
By using a special high-temperature bearing vibration measuring device (frequency analyzer, etc.), the magnitude of vibration can be measured, and the specific situation of the abnormality cannot be inferred from the frequency division. The measured values vary depending on the conditions of use of the high-temperature bearings or the mounting position of the sensors. Therefore, it is necessary to analyze and compare the measured values of each machine in advance to determine the judgment standard.
2.The effect of vibration on high temperature bearings
High temperature bearing vibration is very sensitive to the damage of high temperature bearings, such as peeling, indentation, rust, cracks, wear, etc. will be reflected in high temperature bearing vibration measurement
