Preparation Before Balancing

Check Rotor Mounting: Ensure the rotor is securely mounted to the foundation with no looseness in the connections.
Check Bearing Condition: Inspect the bearings for wear, looseness, or damage.
Inspect Vibration Sensors and Tachometer: Verify that all sensors are in good condition and correctly installed. Sensors should be mounted on rigid parts of the structure.
Check for External Vibration Sources: Ensure there are no other machines or devices operating at the same frequency as the rotor, which could affect the measurements.
Inspect for Cracks and Damage: Check the rotor housing and other structural elements for any damage or cracks.
Determine Resonant Frequencies: Adjust the rotor speed to identify potential resonant frequencies and avoid them during operation.
Check Bolted Connections: Make sure all bolted connections are tightened correctly and meet the necessary safety and strength requirements.

Quick Guide to Balancing with Balanset-1A

1. Equipment Setup:

Install Vibration Sensors: Attach two vibration sensors to the machine's housing at selected measurement points.
Install Phase Angle Sensor: Mount the laser tachometer (phase angle sensor) on a magnetic stand and direct it at the reflective tape attached to an accessible rotor surface.
Connection: Connect the vibration sensors to the X1 and X2 inputs of the measurement block, and the phase angle sensor to the X3 input.

2. Getting Started:

Launch the "Balanset-1A" software from the desktop.
Select the balancing mode: "F2-Single plane" for single-plane balancing or "F3-Two plane" for two-plane balancing.
Enter the rotor data into the corresponding fields in the program.

3. Conducting the Balancing:

Initial Run and Measurement: Start the rotor and perform initial vibration measurements without a trial weight.
Install Trial Weight: Attach a trial weight to the first plane and restart the rotor to measure the vibration.
Measure Vibration Changes: Ensure that vibration or phase changes exceed 20%.
Second Plane: Move the trial weight to the second plane and repeat the measurements.

4. Correction and Verification:

Install Corrective Weights: The program will suggest the weight and angle for installing corrective weights in the first and second planes. Remove the trial weights and install the corrective ones.
Check Balancing: Start the rotor to verify the success of the balancing. If necessary, add additional weights and repeat the check.

5. Completion of the Process:

Verify the vibration levels and ensure they comply with the standards.

Common Balancing Problems and Solutions

Structural Resonance:
Problem: The rotor's vibration frequency coincides with the structure's natural frequency, increasing vibration amplitude.

Solution: Change the rotor speed to identify resonant frequencies and, if necessary, reinforce the structure or modify its installation, for example, by using spring isolators.
Worn Bearings:
Problem: Worn or damaged bearings cause increased vibration.

Solution: Check bearings for wear or damage and replace them if necessary before balancing.
Poor Foundation Mounting:
Problem: Insecure rotor mounting to the foundation causes additional vibrations.

Solution: Ensure the rotor is securely mounted and all fasteners are properly tightened.
Rotor Contacting Stationary Parts:
Problem: Friction or contact between the rotor and stationary parts can cause vibration.

Solution: Ensure there is enough clearance between the rotor and stationary parts.
Shaft Misalignment:
Problem: A misaligned shaft can lead to imbalance.

Solution: Check the shaft for misalignment and, if necessary, straighten or replace it.
Unstable Rotations and Tachometer Errors:
Problem: Unstable rotor speeds or tachometer malfunctions.

Solution: Ensure the tachometer is securely mounted and there are no reflections on the rotor. The rotor should rotate evenly; if speeds are unstable, errors can occur. You can increase the Tacho unevenness value in the program settings.

Problem: Sunlight can saturate the tachometer's sensitive photoelement.

Solution: Create a shade to prevent sunlight from affecting the tachometer.
Loose Bolted Connections:
Problem: Loose bolts can lead to structural instability and additional vibrations.

Solution: Check all bolted connections and tighten them with the appropriate torque to ensure secure attachment of all components.

FAQ

After placing an order, shipping is usually done within a few business days. Delivery time depends on your location. Typically, it is 5-10 days plus customs clearance time.

Balanset-1A and Balanset-4 devices come with a 1-year warranty. In case of technical problems during the warranty period, we will provide repair or replacement of the device.

Balanset devices are known for their high quality and reliability. Breakdowns are rare and mostly due to physical damage.

If the device breaks during the warranty period, you need to contact our support service to organize repair or replacement of the device. After the warranty period expires, we offer paid repair services.

Yes, you can upgrade your old balancing machine by installing the Balanset measurement system on it.

There may be water or bulk material in the rotor. This can also be caused by resonance of the structure at the rotor's rotation frequency, interference from nearby mechanisms operating at the same frequency, cracks, bearing damage, loose bolts, or the rotor touching stationary elements of the structure.

Ensure the angle is correctly measured. Check the stability of the readings in vibrometer mode and for mechanical issues. Try using a weight that is half or even a third lighter than indicated by the device to account for non-linearities.

The standard set includes everything necessary for balancing except for weights and a notebook.

No, there are no monthly payments required when purchasing a Balanset device. You pay for the device and selected accessories once with no restrictions on use.

Any notebook with a Windows 7 or higher operating system will work with the device.

The software for Balanset devices is available in English, German, French, Polish, and Russian.

Yes, our Balanset-1A device is suitable for balancing a wide range of rotors, including Crushers, Fans, Cardan Shafts, Centrifuges, Turbines, Shafts, Pulleys, Electric Motor Rotors, Pumps, Compressors, Propellers, Mulchers, Combine Harvesters, and many other types of equipment.

Balanset-1A is a two-channel device for balancing rotors mounted on two bearings, suitable for equipment such as crushers, fans, augers, etc. Balanset-4 is designed for balancing rotors, such as cardan shafts, mounted on four bearings, and can also be used for rotors on two bearings. Arbalance is a two-channel portable device for balancing that does not require connection to a notebook.

If the tachometer does not read values, check whether it is too far or too close to the reflective mark or whether the laser path is obstructed. Try placing the tachometer at a different angle. Ensure that there is a clearly visible reflective mark on the surface of the rotating object and that the tachometer is correctly set to detect it. In sunny weather the tachometer photocell may be backlit, make a shade.

The rotor may have unstable rotations. In the software settings, find the item "Unevenness" and set a higher value. The tachometer may catch reflections on the rotor. Place it at a different angle, find a place for the reflective mark where the laser will not catch reflections.

Resonance of the structure: If the rotor vibration frequency matches the natural frequency of the structure's oscillations, balancing is impossible. Change the rotor speed and observe the vibration. Strengthen the structure or change its stiffness if necessary.

Bad bearings: Worn or damaged bearings can make balancing impossible. Check the bearings for wear, play, or damage and replace them if necessary.

Shaft misalignment: Check the shaft for misalignment and straighten or replace it if necessary. Misalignment can cause the appearance of the second and third harmonics on the spectrum graph.

Tachometer movement during operation: The tachometer must not move. Aim the laser at one point and keep it there throughout the process. If the laser shifts, return it to its original position.

Incorrect angle measurement for corrective weights: Ensure you are measuring the angle in the direction of rotor rotation.

Rotor touching stationary elements: Ensure there is enough clearance between the rotor and stationary parts of the structure. Any rubbing or touching can cause vibration and reduce balancing effectiveness.

Damaged or worn bearings: Check the bearings for wear, play, or damage and replace them if necessary.
