Reasons why the fan cooling pad impeller is unbalanced


Everyone knows that the balance problem of the fan cooling pad is directly related to the entire operating status. If the impeller frequently has problems, it will have a great impact on the entire use effect. If the impeller is found to be unbalanced, it should be resolved as soon as possible. Before solving these problems, the cause of impeller imbalance should be clarified.

Impeller imbalance caused by wear of the fan cooling pad impeller: During operation, due to continuous erosion by some dust, the impeller wear is extremely irregular, thus causing imbalance of the impeller; due to the high temperature on the surface of the impeller It is easy to oxidize under the environment, forming a thick layer of oxide scale. The bonding force between these oxide scales and the surface of the impeller is also uneven. Some oxide scales will automatically fall off under the action of vibration and centrifugal force, which is also a reason for the imbalance of the impeller .
2. Impeller imbalance caused by impeller fouling: Fouling is due to the moderately high dust particles and high viscosity. When they pass through the fan cooling pad, they will be adsorbed on the non-working surface of the blades under the action of eddy currents. Especially at the entrance and exit of the non-working surface, serious dust scaling is formed and gradually thickens.
When the fan cooling pad impeller is unbalanced, it is necessary to find out the cause and solve it as soon as possible.
