In the animation above, the red circle represents an imbalance, the red arrow represents the force exerted due to centrifugal forces. The green circle represents a correction mass and the green arrow represents the counter-force exerted by this mass to cancel the imbalance force out. This is a very simple representation of a static (single plane) imbalance.
What is 'Workshop Balancing'?
Workshop balancing is a form of rotational balancing which is achieved on a balancing machine in our workshop. Similar to car tyre balancing however on an industrial scale, most impellers/rotors will develop imbalance due to many factors; some unavoidable. It can be detected using Vibration Analysis on site. In static imbalance, there is a single heavy spot in the unit which generates an imbalance force; by applying a balance force in the opposite direction, the two forces cancel out leaving the unit neutral and free of imbalance.
Coupled imbalance can occur with larger plane distance (long rotors for example), this is where there are two static spots on opposite planes are creating the imbalance forces. This can be described as a 'twist' in the unit balance. A combination of both coupled and static is where the opposite planes are out of sync and one side is also heavier than the other, this is called Dynamic Imbalance.
What are the benefits of 'Workshop Balancing'?
Reduce maintenance costs - Imbalance is a large factor in reducing the lifespan of bearings and other mechanical components, therefore by balancing machinery, these components last longer.
Reduced energy costs - units running out of balance generally consume more power as the driver must work harder to compensate, balancing will reduce overall energy costs.
Noise/vibration reductions - Imbalance causes higher vibration and noise levels which can be greatly reduced once a unit is balanced.
Cheaper - Workshop balancing is usually cheaper for smaller units and a tighter balance tolerance is usually easier to achieve in a workshop.
Easier - If a unit is already out for repair, it is convinient to balance it whilst out; and a tighter tolerance can be achieved including some Dynamic Imbalance which in-situ balance may not have access to do.

How we do 'Workshop Balancing'
Workshop balancing is achieved at our workshop in Prenton (contact us for more details). Usually workshop balancing jobs are transported by the clients means however transport can be arranged if required (but will be an additional cost). We offer rush services for jobs which need a quick turn around, as well as callouts for out-of-hours rush jobs requiring balance. Once the balance is complete it will be available for pickup and will be sent with it's balance certificate; this can alternatively be emailed if preferred.
Workshop balancing does have weight and physical size restrictions. Contact us for more details.
