OU "Vibromera" http://goodbal.com/ ru Thu, 07 Sep 2023 00:00:00 +0300 Balancing Mulchers, Combines and Harvesters Introduction: Recognizing the Significance of Dynamic Balancing
The upkeep of rotating machinery in agricultural and industrial settings is paramount. Unbalanced rotors, often seen in mulchers and other farming equipment, can arise due to multiple factors, including component degradation and post-maintenance imbalances. Therefore, timely rotor balancing is imperative to maintain operational efficiency.

The Ramifications of Imbalance
Unaddressed imbalance can lead to unwarranted vibrations, which subsequently accelerate the wear and tear of bearings and other adjacent mechanical elements. Such vibrations can also have a detrimental impact on operator health and safety. Therefore, it becomes essential to conduct regular vibration analysis to gauge the state of your equipment and proceed with the necessary dynamic balancing procedures.

Scope of Our Balancing Services
We offer specialized services in balancing a wide range of rotating equipment, such as:

Rotors and Grinder Shafts
Threshing Mechanisms
Various Types of Augers: Transport, Discharge, and Harvesting
Beating Elements
Self-propelled and Rotary Mulchers, including Mulchers for Logging Equipment
Equipment Designed for Roadside Maintenance and Cleaning
Preliminary Measures Before Balancing
It's crucial to complete any repair or maintenance tasks like blade adjustments, bearing replacements, and welding procedures prior to initiating the balancing process. This is because any subsequent mechanical work can offset the balance achieved, making балансировка измельчителя соломы or mulcher balancing redundant.

In-situ Balancing without Disassembly
Our experts are capable of performing on-site balancing without the need to dismantle the equipment. This ensures efficient and precise rotor balancing while minimizing disruptions to your operations.

Instruments and Approach
To conduct these balancing tasks, we deploy the Balanset-1A portable balancing and vibration analyzer. This advanced instrument facilitates precise measurements and effective remediation.

Compliance with International Standards
Throughout the balancing operation, our objective is to achieve the most minimal residual imbalance possible, while strictly adhering to balancing precision in accordance with GOST ISO 1940-1-2007 standards appropriate for the specific class of machinery.

Conclusion: The Crucial Nature of Balancing Operations
Rotor balancing is not merely a maintenance chore but a vital operation that considerably influences the lifespan and operational efficacy of your machinery. Armed with the proper equipment and expertise, this procedure can be executed promptly and effectively, securing the long-term dependability of your rotating systems.

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)
 

Specifications:

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.

Details:

Amplitude vibration range 0.005-100 mm/sec
Vibration frequency range 5  - 300 Hz
Accuracy - 5% of full scale

Rotation speed measuring 30-90000​  rpm
Phase angle measurement error +-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. 

 

fig.1.1  phase sensor settings

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 (but lower than resonance frequency) 
  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 .
