Dynamic fan balance is when the rotating system does not introduce any other forces or couples. Apart from the required force, the system rotates without any external force or additional pressure. Committing to static or dynamic balance can help increase the life, quality and accuracy of your machines.
Fan balance and rotating equipment
Balance of fan and rotating equipment is important to avoid vibration. Dynamic and static imbalance in heavy industrial machines such as generators and motors can cause catastrophic failure as well as noise and discomfort. To help balance the fan, it simply involves moving the center of gravity to the center of rotation. For the systems to be perfectly balanced, both the force polygon and the polygon must be closed.
What is static fan balance?
Static balance occurs when the center of gravity of the object is on the axis of rotation. This allows the object to remain stationary, with the axis horizontal, without applying a frictional force. Static balance does not tend to rotate due to the force of gravity.
What is dynamic fan balance?
Dynamic balance is when rotation produces no centrifugal or torque forces. This system rotates without the need to apply any external force or couple, other than the force required to support its own weight. When a system or machine is unbalanced, a counterweight is added to prevent stress on the bearings. Dynamic fan balancing is a way to balance machines by rapidly rotating parts and then measuring the unbalance using electronic equipment. The calculated unbalance can then be added or subtracted from the weight until the vibration of the parts is reduced.
What is the difference between static fan balance and dynamic fan balance?
Static balance refers to the ability of a stationary object to balance itself. This happens when the center of gravity of the objects are on the axis of rotation. Whereas dynamic balance is the ability of an object to maintain balance while moving or when shifting between positions. In order for any form of fan balancing to occur, the center of gravity must be placed on the object's support base. The center of gravity refers to the part that is the center of the object's weight. Fan balance plays a very important role in cars. Balancing in machines helps rotating objects to prevent vibration. Vibration in machines can lead to breakdowns. Common breakdowns occur in generators and heavy machinery, so fan balancing can help prevent machine breakdowns. Fan balancing can also involve shifting the center of gravity toward the center of rotation. Dynamic fan balance is when the rotating system does not introduce any other force or couple. Apart from the required force, the system rotates without any external force or additional pressure. Committing to static or dynamic balancing can help increase the longevity, quality and accuracy of your machinery. Unbalanced parts can cause your device to fail, or worst of all, catastrophic failure.
