Dear Users,

To expedite the resolution of issues related to balancing your equipment, please submit your requests following the requirements below. This will help us diagnose the problem more accurately and provide an effective solution.

1. Required Information for the Request

Photos of the Mechanism

• Overall view of the equipment, showing how it is mounted (on a foundation, frame, etc.).
• Vibration sensor placement – show where and how the sensors are installed.
• Operating condition – a photo of the rotor/mechanism in working mode (if possible).

Vibration Data

• Vibration stability and phase:
  • Run the program in "Vibrometer" mode, spin the rotor up to operating speed, and take measurements for 1–2 minutes.
  • Attach a screenshot of the measurement table (similar to this example).
  • If the values are unstable, check:
    • The reliability of the rotor mounting.
    • The condition of bearings and connections.
    • The absence of loose bolts or structural defects.

Balancing and Maintenance History

• Changes in vibration after previous adjustments (if balancing has been performed before).
• Presence of instability (amplitude/phase fluctuations, repeated unbalancing, unusual equipment response).
• Data on repairs:
  • Which components were replaced/repaired.
  • When the work was performed.

2. Key Technical Aspects

Angle Reference Direction

• The device measures the angle from the test weight in the direction of rotor rotation. Ensure this matches your methodology.

Pre-Balancing Checks

• Tachometer stability: Do not move it during measurements—this distorts the phase and angle.
• Axial vibration: If high axial vibration remains after balancing, there may be shaft bending or loose mounts.

Additional Signs of Malfunctions

• Noises, knocks, excessive bearing heating.
• Cracks, play, visible structural deformations.

3. Recommendations

• First test weight: Use 50% of the mass recommended by the device to reduce the risk of overbalancing.
• For nonlinear systems: Refer to our guide on working with nonlinear objects: Balancing Nonlinear Systems.

4. Important!

• If vibration does not decrease after adjustments, stop balancing and check:
  • Bearing condition (wear, clearances).
  • Presence of hidden defects (cracks, loose components).
  • Correct sensor installation.
