What are the reasons for excessive noise during the operation of the box filter?
What are the reasons for excessive noise during the operation of the box filter?The excessive noise during the operation of the box filter may be caused by fan failure, the problem of the filter itself, the problem of the pipeline system, and the non-standard installation. The following is the specific analysis:Fan failure Impeller wear or imbalance: After the long-term operation of the impeller, the weight distribution may be uneven due to wear, or the balance is not adjusted during the installation process, which will cause vibration when the fan is running, resulting in noise. Bearing damage: The bearing of the fan may be worn, lack oil, or damaged after being used for a long time, which will cause the shaft of the fan to be unstable when rotating, resulting in noise and vibration. Motor failure: motor winding short circuit, open circuit or motor bearing damage and other faults may cause abnormal noise during motor operation, and then transmitted to the entire box filter system through the fan. Filter itself problem Filter material blockage: When a large amount of dust and impurities accumulate on the surface of the filter material, resulting in poor airflow, the fan needs more power to push the air through the filter, which will increase the fan load, and the operating noise will increase accordingly. Filter material damage: If the filter material is damaged, the air will form irregular airflow in the damaged area, resulting in noise. At the same time, the damaged filter material may be blown by the airflow and collide with the internal structure of the filter, which will also produce additional noise. Loose internal components: If the supports and partitions in the filter are not securely installed, vibration and collision may occur under the impact of the air generated by the fan, resulting in noise. Piping system problem Pipeline resonance: When the fan is running, it will cause the vibration of the airflow in the pipeline. If the natural frequency of the pipeline is similar to the vibration frequency of the fan, a resonance phenomenon will occur, resulting in a significant increase in noise. Blocked or poor pipeline: If there is a foreign body blocked in the pipeline, or the elbow, valve and other parts of the pipeline are unreasonable design, resulting in poor airflow, which will cause turbulence in the pipeline, resulting in noise. Installation problem Installation is not firm: When the box filter is installed, if it is not fixed, or the installation bracket is not stable, the whole filter will vibrate when the fan is running, thus making noise. Improper installation position: If the box filter is installed near a wall or other obstruction, the airflow may be obstructed when discharged, forming eddy currents and producing noise. At the same time, the uneven installation position may also lead to unstable filter operation and noise. |
