  • How to Identify, Correct a Resonance Condition

    Often, resonance can be confused with the natural frequency or critical frequency. If equipment is operating in a state of resonance, the vibration levels will be amplified significantly, which can cause equipment failure and plant downtime. It is, therefore, important that the running speed of equipment be out of the resonance The vibration of plant equipment: Resonance and Damping,The vibration of plant equipment: Resonance and Damping Published on November 30, 2020 November 30, 2020 • 14 Likes • 0 Comments

  • How to Determine Root Cause of Excessive Pump Vibration

    When plotting the pump "all pass" vibration (at the top of the motor) for the various operating speeds, as shown in Figure 2, the vibration is not seen to peak at any distinct speeds (as would be expected with an unbalance or resonance issue), but instead there is much scatter. The only trend is that the vibration generally increases with speed.Solving plant vibration problems POWER Magazine,May 15, 2006· Good vibration trending data may allow plant operators to identify an emerging vibration problem before equipment damage can occur (Figure 1). 1.
