How to eliminate metallurgical crusher rotor vibration? - EQiblyOnets - 01-26-2025
<h2> with the Balanset-1A Device </h2>
<h3> Equipment Preparation </h3>
<ul>
<li> vibration sensors, optical speed sensor, magnetic base, software package, and included accessories. </li>
<li> Set up the instrument and connect it to your computer via USB. Verify that the software is correctly installed. </li>
</ul>
<h3> Mounting the Sensors </h3>
<ul>
<li> Fix the accelerometers securely to the machine's structure in locations where vibrations are most prominent, ideally near the bearings. </li>
<li> Aim the optical rpm sensor at the rotating shaft and apply a reflective strip to the shaft for phase angle data acquisition. </li>
</ul>
<h3> Software Startup </h3>
<ul>
<li> Open the Balanset application on your PC. </li>
<li> Select the appropriate balancing mode: single-plane or two-plane, depending on the rotor type and your specific requirements. </li>
</ul>
<h3> Measuring Initial Vibration </h3>

</a>
<ul>
<li> Run the rotor up to its operating speed. </li>
<li> The software will measure the vibration level, rotational speed, and phase angle. This data establishes the current imbalance condition. </li>
</ul>
<h3> Attaching the Trial Weight </h3>

</a>
<ul>
<li> Halt the rotation and mount a test weight at a designated position on the rotor, with the weight's value entered into the software (usually in grams). </li>
<li> Run the rotor again, allowing the software to measure the effects of the trial weight on vibration and phase. </li>
</ul>

</a>
<h3> Computing the Compensating Weight </h3>
<ul>
<li> The software uses the measured values to automatically compute the necessary compensating weight's magnitude and placement angle. </li>
<li> The results of the calculation are shown both numerically and visually through charts and graphs. </li>
</ul>

</a>
<h3> Attaching the Corrective Mass </h3>
<ul>
<li> Attach the computed compensating weight to the rotor as indicated by the software's output. </li>
<li> Periodic checks can be performed to ensure the balancing procedure is effectively reducing the vibration. </li>
</ul>

</a>
<h3> Verification and Balancing Completion </h3>
<ul>
<li> After installing the correction weight, run the rotor again and check the residual vibration level. </li>
<li> If the measured vibration falls within the tolerance defined by ISO 1940, the balancing process is considered successful. </li>
<li> If the vibration is still outside acceptable limits, reiterate the process and fine-tune the compensating weight. </li>
</ul>
<h3> Generating a Documentation of the Balancing Results </h3>
<ul>
<li> The program stores the balancing data, allowing you to generate and print a comprehensive report including vibration measurements, corrective weight details, and its angular placement. </li>
</ul>
<h3> Post-Balancing Checklist </h3>
<ul>
<li> Double-check that all weights and sensors are securely fastened. </li>
<li> Confirm that the rotor spins freely and quietly, without any unusual sounds or vibrations. </li>
<li> If the rotor is part of a complex mechanism, verify the proper interaction of all its components. </li>
</ul>
<p> Following this procedure enables accurate balancing, minimizes vibration, and prolongs the service life of the equipment. </p>
