Portable vibration analysis equipment for maintenance and repair
Rotors play a crucial role in the operation of various machines and equipment. Ensuring the proper balance of rotors is essential for their efficient performance and longevity. One of the key tools used for balancing rotors is the Balanset-1A device, designed by Vibromera.
Balanset-1A enables rotor balancing in one and two correction planes, depending on the structural characteristics of the rotor being balanced. Balancing in one plane, known as "static balancing," is typically used for narrow disc-shaped rotors with minimal axial runout. Examples of rotors suitable for static balancing include grinding wheels, pulleys, disc flywheels, gear wheels, clamping chucks of lathes, narrow fans, and more.
On the other hand, balancing in two planes, termed "dynamic balancing," is employed for long shaft-like rotors. Typical examples of rotors that require dynamic balancing include electric motor and generator rotors, compressor and pump rotors, turbine and fan impellers, wide grinding wheels, spindles, mill shafts with hammers, and others.
The process of balancing a rotor using the Balanset-1A device involves several key steps, from equipment preparation to the installation of correction weights.
Equipment Preparation
1. Place the vibration sensors perpendicular to the rotor's axis of rotation.
2. Attach the laser tachometer to a magnetic stand, directing it towards the reflective tape on the pulley.
3. Connect the sensors to the device and link the device to a laptop via USB.
4. Launch the Balanset software, selecting the two-plane balancing mode.
Initial Vibration Measurement
Prior to balancing, suspend a test weight and record its weight and installation radius. Start the rotor and measure the initial vibration level to determine the magnitude and phase of the initial imbalance.
Balancing in the First Plane
Position the test weight in the first balancing plane aligned with the first sensor. Start the rotor to measure the vibration level. It is crucial that the amplitude or phase changes by at least 20%, indicating partial correction of the imbalance.
Balancing in the Second Plane
Move the test weight to the second plane (where the second sensor is located), restart the rotor, and take measurements. These data will help the program calculate the precise position and weight of the correction weights.
Imbalance Correction
Based on the data obtained, the Balanset program will suggest correction weights and their installation angles for both planes. Remove the test weight, prepare the correction weights following the program's recommendations, and install them at the required angle in the rotor's rotation direction from the initial test weight position.
Verification and Completion of Balancing
Run the rotor for a final balancing check. If the vibration has decreased to an acceptable level, the process is complete. If further correction is needed, the program will indicate where and how much additional weight to install.
