What Is Phase Difference Vibration?
A Once-per-Revolution Radial Vibration Usually Means Rotor Unbalance. Use Phase to Prove Imbalance Is the Problem. to Confirm Imbalance, Measure the Horizontal...

Besides, what does vibrating in phase mean?
Phase of vibration. any part of the path described by a particle or body in making a complete vibration, in distinction from other parts, as while moving from one extreme to the other, or on one side of the line of rest, in distinction from the opposite.
Similarly, what does 1x vibration mean? The expression “1x” means vibration at the same frequency as the running speed of the machine. As a general rule, however, high vibration at 1x indicates either unbalance or misalignment.
Subsequently, one may also ask, what is phase of a wave?
Phase is a particular point in time on the cycle of a waveform, measured as an angle in degrees. Phase can also be an expression of relative displacement between or among waves having the same frequency - the "phase difference". Leading phase refers to a wave that occurs "ahead" of another wave of the same frequency.
What causes vibration in rotating equipment?
Vibration can be caused by one or more factors at any given time, the most common being imbalance, misalignment, wear and looseness. Imbalance - A "heavy spot" in a rotating component will cause vibration when the unbalanced weight rotates around the machine's axis, creating a centrifugal force.
