Portable Field Balancer "Balanset-1A"

1. Introduction

Balanset-1A is a portable dynamic balancer designed to balance rigid rotors in their own bearings (in-situ), or serve as a measuring system in balancing machines. It offers both single- and two-plane dynamic balancing services for a variety of rotating machinery, including fans, grinding wheels, spindles, crushers, and pumps. The accompanying balancing software automatically provides the correct balancing solution for both single-plane and two-plane balancing.

User-Friendliness

Balanset-1A is designed to be simple to use, even for those who are not vibration experts.

Balancing Procedure

The balancing procedure employs a 3-run method, incorporating the addition of a test mass at every point of balance, also known as the Influence Coefficient Method. The software automatically calculates the balancing weights and their placement (angle), displaying the results in a table and saving them in an archive file.

Reporting and Data Visualization

The system allows for the printing of a balancing report. Additionally, waveform and spectrum of vibration charts are available for more in-depth analysis.

Balanset-1A is a comprehensive solution for dynamic balancing, offering a range of features to ensure accurate and efficient balancing of rotating machinery. Its user-friendly interface and advanced software make it an ideal choice for both experts and non-experts in the field of vibration analysis.

Table 1: Step-by-Step Operations for Balancing

Initial Run (Run 0) - Start-up Without Test Weight

Run the machine at its operating speed (ensure the speed is far from the resonance frequency of the construction).
Click on F9-Start to measure the vibration level and phase angle without a test weight.
The measuring process may last between 2-10 seconds.

First Run (Run 1) - Test Weight in Plane 1

Stop the machine and mount a test weight of suitable size arbitrarily in Plane 1.
Start the machine, click on F9-Run, and measure the new vibration level and phase angle.
The measuring process may last between 2-10 seconds.
Stop the machine and remove the test weight.

Second Run (Run 2) - Test Weight in Plane 2

Mount a trial weight of suitable size in Plane 2.
Start the machine again, click on F9-Run, and measure the vibration level and phase angle once more.
Stop the machine and remove the test weight.

Calculation Step (Step 4)

The correction weights and angles will be calculated automatically and displayed in a popup form.

Correction Run (RunC)

Mount the correction weights at the positions indicated in the popup form, at the same radius as the test weights.
Start the machine again and measure the amount of residual unbalance in the rotor to assess the success of the balancing job.

Post-Balancing Actions

After balancing, you can save influence coefficient balancing (F8-coefficients) and other information (F9-Add to archive) for future use.

By following these step-by-step operations, you can achieve precise balancing and significantly reduce vibration levels in your rotating machinery.

4. Additional Features of Balanset-1A

4.1. Vibrometer Mode

Activating Vibrometer Mode

-To activate the Vibrometer mode, click on the "F5-Vibrometer" button in the main window for two-plane (or one-plane) balancing.
-To initiate the measuring process, click "F9-Run".

Understanding Vibrometer Readings

-V1s (V2s): Represents the summary vibration in Plane 1 (or Plane 2) calculated as mean-square.
-V1o (V2o): Indicates the 1x vibration in Plane 1 (or Plane 2).
