Portable multiplane balancer "Balanset-4"
1. Introduction

Balanset-4 is 4-channels portable balancer used to balance rigid rotors in their own bearings (in-situ) or as measuring system in the balancing machines. It provides (1..4)-plane dynamic balancing services for fans, grinding wheels, spindles, crushers, pumps and other rotating machinery. Balancing software provides the correct balancing solution for (1..4)-plane balancing automatically.  Balanset-4 is simple to use for non-vibration experts.

Balanset-4 includes:
  • Interface unit
  • 4 vibration sensors
  • 1 optical sensor (laser tachometer)+ magnetic stand
  • scale
  • Software ( notebook not included - supplied by additional order)

    4x vibration sensors based on Analog Devices ADXL series.
    1 x optical sensor (laser)
    1 x USB interface module with software for PC connection
    Software provides measuring vibration, phase angle, calculation of value and angle of the correcting mass.

    Amplitude vibration range 0.05-100 mm/sec
    Vibration frequency range 5 - 300 Hz
    Accuracy - 5%
    Correction planes 1 or 2 or 3 or 4
    Rotation speed measuring 150-60000   rpm
    Phase angle measurement accuracy +-1 degree
    Power supply - from PC USB port
    Weigh - 4 KG

2. Prepare to work. Software and hardware setup for multiplane balancing.
2.1  Driver installation
Install drivers and Balanset-4 software from installation flash disk.
Insert USB cable to computer USB port. Interface module power supplied from USB port.
Use   shortcut to run the program.

2.2  Sensors installation
Install sensors as shown  on the fig. 1,2

Connect cables
- vibration sensors to connectors X1,X2,X3,X4
- phase laser sensor to connector X5

Run 0 - Start-up without test weight.
  • Run the machine at its operating speed (be sure that operating speed is far from resonance frequency of construction)
  • Click on F9-Start and measure  the vibration  level and  phase angle  in turn without test weight. Duration of the measuring process  may amounts  2-10 sec.

Run 1-4 - Test weight in plane 1-4
  • Mount a trial weight of  suitable size in plane 1(2,3,4).
  • Start the machine again, click on F9-Runand measure the vibration level and phase angle once more.
  • Stop the machine and remove the test weight
Step 4 - Calculation
  • The values of the correction weights and angles required will be calculated automatically and shown in popup form.

  • Mount the correction (balance) weights  at the  positions indicated in popup form at the same radius as the test (trial) weights (as shown in the figure in right column).
  • Start up the machine again and measure the amount of residual unbalance in the rotor, to see how successful the balancing job has been.
    After balancing you can save influence coefficient balancing (F8- coefficients) and other information (F9- Add to archive) and use it later. (see 4.3, 4.4)
4. Other features
4.1 Vibrometer mode.
To select Vibrometer mode click "F5- Vibrometer" button in the main window for multiplane balancing (fig.1)
To start the measuring process click "F9-Run"
V1s-V4s - summary vibration in planes 1-4 (mean-square) V1o-V4o - 1x vibration in planes 1-4 (1x harmonic value)
4.2 Influence balancing coefficients 
If you save the results of previous balance runs, you can eliminate the test weight run and balance the machine using its saved coefficients.  Select "Secondary" in the "Type of balancing" window and click "F2 Select" button to choose previous machine type from list.
To save coefficients after balancing click "F8-coefficients" in the balancing result pop-up window (see Tab.1) and then click "F9-Save" button. Input machine type ("Name") and other information in the table.
4.3 Rotor balancing frchives and reports.
To save balancing information click "F9- Add to archive" in the balancing result pop-up window (see Tab.1). Input machine type ("Name") and other information in the table.
To open previous saved archives click "F6-Report" in the main window.
To print report click "F9-Report"
4.4 Charts 
To view charts of vibration click on "F8-Diagrams"
Two kind of charts available "Total vibration" and  "Vibration on rotor revolution frequency" (for example, for 3000 rev\min frequency is equal 50Hz)
