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

2. Prepare to work. Software and hardware setup for two-plane balancing.
2.1 Driver installation Install drivers and Balanset-1 software from installation flash disk. Insert USB cable to computer USB port. Interface module supplied from USB port. Use shortcut to run the program. 2.2 Sensor installation Install sensors as shown on the fig. 1,2,3 Connect cables - vibration sensors to connectors X1 and X2 - phase laser sensor to connector X3 fig.1 Two-plane balancing scheme
Install reflector mark on the rotor and check RPM value on the phase sensor when rotor rotate. fig.2 Phase sensor settings
3. Balancing procedure
fig.3 Main window for two-plane balancing
After sensors install click on "F7 - Balancing" button and set balancing parameters. Then click "F9-Next" fig.4 Balansing settings
Then make step-by-step operations as shown in the Table 1 below. |
Table 1. Step-by-step operations
Run 0 - Start-up without test weight.
2. Run the machine at its operating speed (be sure that operating speed is far from resonance frequency of construction)
3. 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. fig.7 Two plane balancing window. Original vibration
|
Run 1 - Test weight in plane 1
4. Stop the machine and mount a test weight of suitable size arbitrarily in plane 1.
5. Start up the machine, click on F9-Run and measure the new vibration level and phase angle. Duration of the measuring
process may amounts 2-10 sec.
6. Stop the machine and remove the test weight fig.8 Two plane balancing. Vibration after balancing
|
Run 2 - Test weight in plane 2
7. Mount a trial weight of suitable size in plane 2 . 8. Start the machine again, click on
F9-Runand measure the vibration level and phase angle once more.
9. Stop the machine and remove the test weight

Step 4 - Calculation
10. The values of the correction weights and angles required will be calculated automatically and shown in popup form. fig.5 Two plane balancing. Correction weights calculation

RunC
11. 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). 12. 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 two-(one-) plane balancing To start the measuring process click "F9-Run" V1s (V2s) - summary vibration in plane 1(2) (mean-square) V1o (V2o) - vibration in plane 1(2) (first "revolution" harmonic value) In the right side you can see spectrum window. Measuring data files can be saved in archive.
| 4.2 Influence 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 Archives 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) |
