Balancing set "BalCom-1"

User manual 
rev 1.0

Jun  2012

1. Introduction

 BalCom-1 is portable balancer  used to balance rigid rotors in their own bearings (in-situ) or as embedded measuring system in the portable balancing machines. It provide on-situ (field) 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. 
 BalCom-1 is simple to use for non-vibration experts.


BalCom-1 includes:

1 - Interface unit
2 - two vibration sensors 
3 - 1 optical sensor (laser tachometer)
4- scale
5 - Software ( notebook not included - supplied by additional order)


2x vibration sensors based on Analog Devices ADXL series.
1 x optical sensor (laser)
1 x interface module with software for PC connection
Software provides measuring vibration, phase angle, calculation of value and angle of correcting mass.


Amplitude vibration range 0.005-100 mm/sec
Vibration frequency range 5  - 300 Hz
Accuracy - 5% of full scale
Correction planes 1 or 2
Rotation speed measuring 30-90000​  rpm
Phase angle measurement accuracy +-1 degree
Power  -  140- 220VAC 50Hz
Weigh - 1.4 KG

2. Prepare to work. Software and hardware setup for two-plane balancing.

Install drivers and BalCom-1 software from installation CD.
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 below

Connect cables 
- vibration sensors to connectors X1 and X2
- phase laser sensor to connector X3

fig.1 Main window for two-plane balancing

 Install reflector mark on the rotor and check led light on the phase sensor when rotor rotate.

3. Balancing procedure

After sensors install click on "F7 - Balancing" button and set balancing parameters. Then click "F9-Next"

 Make step-by-step operations  as shown in the Table 1.

  Table 1
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.

Correction weight mount

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 
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-Run   and 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.  
 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.


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.

4.4 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"


4.6 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)
