It is a process that is done to evenly distribute the mass of the propeller (fan blades) to avoid vibrations and vibrations caused by imbalance [1, 2]. This process is necessary to maintain the optimal performance and longevity of the fan, and it is done in two main ways: static balance and dynamic balance [1, 2].
Static balance: In this method, the fan impeller is placed on sensitive bearings and its heavy points are identified [1, 2]. Then by adding or removing weights, the weight of the propeller is balanced so that it does not tilt or move at rest [1, 9].
Dynamic balance: this method is performed while the propeller is rotating, and using advanced devices, inconsistencies are identified and corrected at high speeds [1, 2].
The importance of centrifugal fan balance:
Increasing the useful life of the fan:
The correct balance prevents the creation of destructive vibrations and vibrations, and as a result, the useful life of the fan increases [1, 2].
Reducing energy consumption:
Balanced fans work with higher efficiency, and as a result, energy consumption is reduced.
Reducing noise:
Vibrations caused by lack of balance, They produce annoying noises that can be reduced by balancing the fan [1, 2]. Preventing early failures: Lack of balance can cause early failure of mechanical parts of the fan such as bearings, shafts, and blades [1, 3]. Improving system performance: By balancing the fan, the overall performance of the air conditioning system or the industry in which the fan is used can be improved. finds [1, 2].
Fan balancing services:
On-site balance:
Many companies provide dynamic balancing services at the customer's location, which eliminates the need to separate the fan from the system.
Vibration analysis:
Before balancing, vibration analysis is performed to identify the cause of the imbalance and choose the best balance method.
Test and evaluation:
After balancing, testing and re-evaluation It is possible to ensure the correct operation of the fan.
