​What causes excessive vibration in the bearings of wear-resistant high-pressure centrifugal fans?

What causes excessive vibration in the bearings of wear-resistant high-pressure centrifugal fans?As is well known, bearings are a critical component of wear-resistant high-pressure centrifugal fan systems. However, during actual operation, prolonged use and wear can lead to bearing malfunctions. One of the most common issues is excessive vibration in the bearings of these fans. So, how can this problem be addressed? As users, we must recognize the detrimental effects of this anomaly. During operation of wear-resistant high-pressure centrifugal fan units, excessive bearing vibration can lead to issues such as bearing and blade damage, bolt loosening, and damage to housings and air ducts. In severe cases, the safe operation of the machine itself may be compromised. However, excessive bearing vibration can stem from numerous causes. It is essential to analyze the root cause based on various phenomena and develop appropriate countermeasures. By doing so, one can often achieve twice the results with half the effort. For instance, during actual operation, dust accumulating in the non-working areas of the blades due to continuous processing may cause abnormal vibration in the boiler wear-resistant high-pressure centrifugal fan unit. The primary symptom is a sudden increase in vibration during machine operation. This occurs because when gas enters the propeller, it enters at a certain angle relative to the working surface of the rotating blades. According to fluid dynamics principles, the gas forms vortices on the non-working surface of the blades. As a result, dust particles in the gas gradually accumulate on this non-working surface due to the influence of these vortices. As operating time increases, blades become fully coated with dust. When dust mass reaches a certain weight, centrifugal force from the impeller's rotation ejects most particles. Since dust accumulation is uneven across blades, dust mass collection or ejection timing is not synchronized. Consequently, the uneven distribution of accumulated dust on the blades leads to an unbalanced mass distribution in the propeller, increasing vibration in the wear-resistant high-pressure centrifugal fan. To address this situation, it is necessary to remove dust from the blades of the wear-resistant high-pressure centrifugal fan assembly in a timely manner to restore impeller balance and reduce fan vibration.
