Portable field balancer "Balanset-1A"

1. Introduction
Balanset-1A is portable dynamic 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-1A is simple to use for non-vibration experts.
Balancing procedure uses 3-run method with adding the test mass in every place of balancing (Influence Coefficient Method). Software calculate balancing weghts and place (angle) automatically, show it in the result table and save in archive file. Also you can print balancing report. Waveform and spectrum of vibration charts are possible.

Balanset-1A includes:

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

Correction planes 1 or 2
Rotation speed measuring 150-60000   rpm
Phase angle measurement accuracy +-1 degree
Power  -  140- 220VAC 50Hz
Weigh - 4 KG

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

2.1  Driver installation
Install drivers and Balanset-1A 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

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.

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-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.

 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.
