Good quality balancing
Functionality

The “Balanset-1” device is a portable balancing unit designed for balancing the rotors revolving in their own bearings in one or two correction planes.

The equipment includes: two vibration sensors, a phase angle sensor and a measuring unit connected to a tablet or a laptop. It can be applied when performing installation and repair work in order to reduce the dynamic loads affecting the bearing units of machines due to their imbalance. At the same time, the service life of machines and mechanisms increases significantly. The balancing unit makes it possible in many cases to eliminate the need for specialized balancing machines, since the rotor is balanced in its own bearings without disassembling the mechanism.

The modified “Balanset-1” can be used as a measuring system of the balancing machine, if ever. The whole balancing process, which includes measuring, processing and displaying information about the weight and installation place of corrective weights, is performed automatically and does not require additional skills beyond the operational manual.

The results of all balances are stored in the Balancing Archive and, if necessary, can be printed as certificates in pdf format. In addition to balancing, the “Balanset-1” device can also be used as an ordinary vibration meter, providing the ability to measure the root mean square value (RMS) of the total vibration, RMS of the vibration reverse component and the measured rotation rate. Also, the “Balanset-1” device provides an opportunity to display graphs of the time function and vibration spectrum by vibration velocity, which can be useful when analyzing the technical condition of a balanced machine.


Portable 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.

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.

Two plane balancing window







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.  
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 .
