EI Balance. EI-2000 Balancing machine

 

EI-2000 is a Balancing Machine ideal for almost all kind of rotating parts weighting between 50 and 2000 kg such as rollers, motor rotors, crankshafts, mills among others. EI-2000 Balancing machine uses a soft bearing system built using light and resistant materials in order to decrease inertia.

Features
  • Single and two planes balancing
  • Variable speed (Optional with an inverter)
  • Adjustable pulleys
  • Three liberty axes for each pedestal to set free movements.
  • Manual adjust for power transmission and supports distance.
  • Bearing based soft bearing system to avoid mechanical looseness
  • Axial supports
  • Cantilever bearing support
  • Easy calibration

Software

On the main screen, the
system has particular data of
the measured signal as:

  • Maximum amplitude
  • RMS value
  • Tachometer
  • Polar Graphs
  • Real-time graph
    amplitude vs time
  • FFT graphs (Frequency graphs)

This allows users to have complete description of the machine's vibration, and at the same time how the unbalance vibration is being reduced.

FFT calculations

Fast Fourier Transform The EI-BALANCE performs its calculations using the Fast Fourier transform (FFT). The resolution of the spectra is adjustable and you can choose up to several million lines of resolution.

FFT

  • Frequency accuracy of 99.9% with a 10 second sample
  • Measurement window (defined by the user)
  • Harmonics, Hz and CPM
  • 1600 Points FFT on real time, 30 000 on basic recording and adjustable up to 1 000 000
 
Balancing Calculator
Balancing Calculator

EI-BALANCE has a calculator for single and two planes balancing; this calculator uses the influence coefficients method. Therefore it is not necessary to establish the dimensions of your rotor and their bearings position (cantilever, distance between bearings, etc.)
