Early Detection

Changes in vibration occur early, giving ample time for action.

Proactive Action

Pinpoint issues to efficiently deploy of maintenance resources.

Optimal Operation

Detection of vibration abnormalities can prompt action, avoiding future catastrophic failures.

Insightful Measurements

3 Axes of Acceleration Data

X-Y-Z vibration measurements provide increased radial and tangential sensitivity.

More High Frequency

Helps detecting vibration changes in higher frequency harmonics.

More High Resolution

Separates important frequencies to reveal the true cause of defect.

 

+ Meaningful Analysis

Analysis of Acceleration

BELT RESONANCE

BELT RESONANCE

Belt Resonance can cause high amplitudes should belt’s natural frequency coincide with either the driving or driven sheave’s RPM. Belt natural frequency can be altered by changing the length or tension of the belt. The 1X RPM peak increases in the spectrum if the belt natural frequency coincides.

OIL WHIRL INSTABILITY

OIL WHIRL INSTABILITY

Changes in oil viscosity, temperature, excessive bearing wear/clearance and external preloads can induce oil whirl. Oil whirl instability occurs at .40-.48X and considered excessive when the amplitude exceeds 30%. 

MASS UNBALANCE

MASS UNBALANCE

 Force unbalance will increase amplitude by the square if speed below first rotor critical. (eg: 2X speed increase = 4X higher vibration)

ROTOR PROBLEMS

ROTOR PROBLEMS

Broken or cracked rotor bars or shorting rings, bad joints between the rotor bars and shorting rings, or shorted rotor laminations will produce high 1X running speed vibration with pole pass frequency sidebands (Fp). This generates sidebands around the second third, fourth and fifth or more running speed harmonics.

TOOTH WEAR

TOOTH WEAR

High amplitude commonly at either 2X GMF or 3XX GMF is the key indicator for tooth wear. High amplitude side bands at running speed of the bad gear is present when wear is notable. Side bands are a better indicator since GMF might not change in amplitude. 

WORN, LOOSE, OR MISMATCHED BELTS

WORN, LOOSE, OR MISMATCHED BELTS

Belt frequencies are below the RPM of either the motor or the driven machine. These faults cause 3 to 4 multiples of belt frequency. Often 2X belt frequency is dominant
