What are the precautions for maintenance and upkeep of a large ceiling fan?

1、 Repair and maintenance of circuits:

1. Check whether the mechanical switch action of the regulating valve is reliable and flexible, and whether the switch angle mark is clear.

2. Manually check whether the indicator lights, voltage, and ammeter are working properly, whether there are any abnormal sounds during the operation of various parts of the industrial fan, and whether the three current values are balanced.

3. Check if the components in each remote control box are functioning properly.

4. For three consecutive starts and stops, please check if the remote control at each point is correct and reliable.

5. Run for two hours and observe whether the temperature of the motor bearings and the temperature rise of the motor are normal. The fan is running normally. For industrial fans, regular maintenance should be carried out every six months and the situation should be recorded to ensure the normal operation of the industrial fan.

2、 Maintenance and upkeep of motor fan blades

1. Disconnect the main power supply and check if the motor grounding wire is in good condition.

2. Tighten the screws and couplings of each component.

3. Check whether the insulation resistance of the motor meets the requirements and check the main circuit contacts. If the contacts are severely burned, they should be replaced.

4. Due to the prolonged exposure of fan blades to the outside during use, they are prone to dust contamination and therefore require proper maintenance.
