Maintenance Precautions

 

1. Under normal conditions, if the unpowered fan runs continuously for about one month, it is necessary to inject calcium-sodium-based grease or molybdenum disulfide grease into the bearing with a butter station. The fan runs continuously for 3-6 months, and the grease should be replaced once to fill 2/3 of the bearing space.

2. Regular maintenance of unpowered fans to eliminate dust and dirt inside the fans.

3. During the startup, shutdown or operation of the unpowered fan, if abnormal conditions are found, including temperature, vibration, noise, etc., they should be overhauled immediately.

4. Use the adjusting device to keep the triangle tape evenly tensioned and not too loose or too tight. The length of several triangle tapes should be the same as possible.

5. For unused standby machines or fans that have been out of service for a long time, the rotor should be rotated by 120°-180° regularly to prevent the main shaft from bending. Add a valve to the inlet or outlet of the roof unpowered fan, close it when starting, and open the valve after operation until it reaches the specified working condition, and the inner ring and the shaft fit tightly.

6. In order to ensure personal safety, the maintenance of the roof unpowered fan must be carried out during shutdown
