VIBROPORT 80 - Applications & Solutions

VIBROPORT 80 is designed for a broad range of applications by providing dedicated application modules for specific requirements.

General Machine Condition

If you want to check if your machine is within the operational vibration limit as per DIN ISO 10816, 7919 or the manufacturer's limit values, the Overalls Module is your choice!

The characteristic values comprise:

  • Overall vibration values
  • Rolling-element bearing condition values
  • Speed of rotation
  • Process values
  • Crest factor
  • Max. X/Y

Diagnosis of Faults

To diagnose the location and severity of common faults in rotating machinery (e.g. generators, turbines, fans, aircraft engines, pumps, compressors, motors), the FFT-Analyzer is the appropriate application module.

The following faults are typically diagnosed by an FFT spectrum:

  • Unbalance
  • Bearing faults
  • Bent shaft
  • Misalignment

 

Reduction of Unbalance

Unbalance occurs in nearly all types of rotating machinery. Typically, the following machines can be balanced by means of the VIBROPORT 80 Balancer Module:

  • High-precision machines
  • Small and large electrical motors
  • Automotive and railway engines
  • Reciprocating compressors
  • Fans, gears, pumps, hydraulic machines

Identification of Structural Resonance Frequencies

Coincidence between Rotational Speed and Resonances

For optimal operation of a machine, it is important to avoid (or minimize the duration) of the coincidence between the rotational speed and the structural resonance frequencies. This will minimize high vibrational loads during the run up, coast down or steady-state operation of the machine.

The Tracking Module allows you to determine the critical frequencies based on rotational excitation. Typical applications include:

  • Variable speed machinery
  • Centrifugal turbines and compressors
  • Engine tests
  • Machines operating during a run up or coast down

Identification of Structural Resonances of Immovable Objects

In combination with an Impact Hammer, the Transfer Function Module is used mainly to test immovable objects such as

  • Foundations and bearings

  • Pipe works, conduit systems or frameworks
  • Cracks or poor bonds between parts
  • Natural frequencies of a rotor

Data Recording & Post-Processing

Do you need to record a raw dynamic signal over a long time and save it in a standard file format for post-processing? No problem with the VIBROPORT 80 Time Signal Module. Information can be recorded from:

  • Impulse events
  • Transient events
  • Random events
  • Machine cycles with start and stop phases

The data will be saved in a *.wav format, which can be processed by Rex and other types of analysis software.

Machine Quality and Final Acceptance Check

If you need to make quality checks in mass production and compare the machine state to pre-defined values or standards, the Acceptance Test Module is the what you are looking for. It is typically used for:

  • Noise and vibration quality checks
  • Aircraft engine health checks
  • Testing after service
  • General sound level measurements
