What are the maintenance items for industrial roof fans?

1. Industrial roof fans have different maintenance cycles due to different environments. If used in a dusty environment, the frequency of maintenance should be shorter.
2. When maintaining industrial roof fans, be sure to unplug the power supply before doing maintenance.
3. When the industrial roof fan is running, the fan blades are exposed and dust accumulates, so wipe the fan blades regularly to keep them clean.
4. While wiping the fan blades, carefully observe whether the fan blades have cracks. If so, replace them regardless of the size of the cracks.
5. Since the machine has a certain vibration when the fan is running, the screws may loosen. Carefully check the condition of each screw and tighten them one by one to avoid accidents when the fan is running.
6. The air valve is connected to many parts inside the machine, and it is also easy to loosen. If a screw is found to be off, the screws should be added and tightened in time.
7. Check whether the insulation resistance of the fan motor is in normal use. If not, replace it in time.
