What Key Points Should Be Considered When Maintaining Low-Noise Duct Fans?

Even if a low-noise duct fan is of high quality, its failure rate will continue to rise if users fail to perform regular maintenance. Consequently, the equipment’s service life will be shortened. Therefore, when performing maintenance on low-noise duct fans, it is essential to be thorough and meticulous to ensure everything is done correctly. So, what should be considered during maintenance? First, as part of routine operations, low-noise duct fans should be serviced at least once every six months. During maintenance, inspect the shaft seal and make appropriate adjustments based on actual conditions. Also, check the belt tension and verify that the flexible connections are intact. Additionally, carefully inspect the fan’s coupling for abnormalities and check whether the bearings, seals, and coupling show wear in accordance with specifications. Furthermore, check the rotation of the blades in the airflow regulator. After confirming there are no abnormalities, promptly measure the vibration values of the bearings at the non-shaft end of the motor, including horizontal, vertical, and axial displacement data. It is important to note that we also need to measure the vibration values of the low-noise duct fan’s housing as needed. If the measured value does not exceed 4.5 mm/sec, the condition is good; if they exceed this value, repairs should be carried out promptly. Furthermore, visually inspect the equipment housing, brackets, vibration-damping pads, and impeller for corrosion. For example, areas where paint has peeled off may require repainting. Do not forget to check the surrounding area for debris and ensure that both the interior and exterior of the low-noise duct fan are clean; promptly remove dust and impurities. In summary, to improve equipment utilization, it is essential to perform thorough maintenance on the low-noise duct fan.
