How to measure the vibration value of air compressor, and where is the measuring point?

Vibration shall be measured in the axial, horizontal and vertical directions of the motor, gearbox, shaft and all bearings of the air compressor as required.

Some bearings are located inside the housing, so sensors cannot be placed. Instead, sensors can be placed on the housing to measure vibration.

Measure with a vibrometer. After measurement, it is compared with the value required by the standard. If it exceeds the standard, it will be unqualified.

Check the installation level, gaskets and other fixing contents.
