ACMEI offers dynamic balancing service which is an operation of making the center of gravity of the rotary mass in line with the axis of rotation to reduce the centrifugal force and resultant couple which are the main causes of the vibration.
Imbalance can caused by a number of factors including incorrect assembly, material build-up, rotor sag, thermal growth and component loss.
Balancing technique "in situ " is useful in open access rotors such as fans, rollers, spindles, rotors or in closed access clearing dishes pre - installed, as the case of vertical pumps, turbines, etc.
The main advantage of balance "in situ" is the cost savings in the removal, transport, and assembly bench execution large rotors or weights, or installed in inaccessible locations requiring cranes or other hazardous operations.
All rotating components experience significant quality and performance improvements if balanced. Balancing is the process of minimizing vibration, noise and bearing wear of rotating bodies.
When unbalance has been identified and quantified, the correction is straightforward. Weight has to be either added or removed from the rotating element. The ultimate aim being to reduce the uneven mass distribution so that the centrifugal forces and hence the vibrations induced in the supporting structures are at an acceptable level.
Implementing a balanced work according to the recommendation that includes ISO - 1940 provides the following advantages:
- Decrease fatigue loading on the supports and increasing the useful life of the bushings and bearings.
- Reduced vibration and noise that could affect the quality of the processed product.
- Saving energy in the rotor drive less heating and electric motors.
- Increased reliability of the equipment and process as well as of operational safety by preventing any release of rotor by the action of centrifugal force.

Balancing: Single, Dual and Multiplane Vibration Balancing
Our Balancing Solutions are software modules for balancing rigid and flexible rotors. These modules are well-suited for shop balancing or in-situ field balancing. They are designed to run on ACMEI analyzers
2 modules are available:
- The Single/Dual plane software module is particularly suited for shop or field balancing of rotors operating in their rigid body region (well below their first critical speed).
- The Multiplane software module is designed to balance rotors above the first critical speed: meaning in the region where the rotor deforms and reaches its first bending mode.
- Acquisition from a wide range of OROS 3-Series instruments
- Accepts signals from accelerometers, velocimeters or proximity probes
- Up to 32 sensors depending on the instrument platform
- Real-time data for the balancing operation (1X amplitude and phase)
- High phase accuracy (6.4 MHz oversampled tach)
- Flexible weight map configuration with correction mass split or by step of 1
- Add or remove weight by drilling
- Prognostics of residual vibration (“what if” feature)
- Trim balancing
Single/Dual Plane Balancing
Save time with the Balancing Solution
With this technique, the number of machine starts is reduced, for example only 2 starts are necessary for a one plane balancing. When a balancing test has been achieved, the unbalance correction can be readjusted periodically without any further test thanks to the trim balance method.
The Perfect Field Solution
The Balancing Solution is part of the family of solutions offered by us for Rotating Applications. Balancing rotors is a common practice during fault diagnosis on rotating machinery. Based on the Our portable and rugged analyzers, the Balancing solution is well adapted for field measurements.
