Vibration and Balancing Industrial Limited

IMPROVE QUALITY PRODUCTION AND SAFETY WITH PRECISION BALANCING.

PRECISION BALANCING

• reduce vibration
• lower maintenance costs
• optimize machine running time
• increase bearing life
• reduce wear
• reduce energy consumption

The most common cause of vibration in rotating equipment is imbalance. Unbalanced machines cause an increased load on bearings and is a common cause of vibration. This inevitably leads to mechanical stress. Eventually, the result is costly mechanical problems. It can also contribute significantly to increased energy consumption and reduced production time. Unbalanced machinery is unsafe, unreliable, uneconomical.

How do things get out of balance?
The displacement of the mass centreline from the rotor’s axis by an eccentricity in the distribution of the rotor mass causes components to become unbalanced. This causes vibrations that can lead to structural fracture or bearing failure, resulting in damage to the machine.

Fixing the problem
The faulty component is installed in a balancing machine and by measuring the ‘heavy’ point in relation to the centreline while the part is rotating, the required balance correction can be found. If this is at a single axial point on the rotor the balance is said to be ‘Single-plane’.

Single-plane balancing will, in most instances, eliminate vibrations from rotors that are short in length, such as narrow section pulleys and fans.
For the majority of components or assemblies of significant length, particularly rotors, dynamic balancing is required. Our facility houses four dynamic balances, each capable of balancing articles up to 4.5 metres in diameter and ten tonne in weight. Rotors sometimes have two ‘heavy’ points at opposite ends of the component that will act Independent.
