Maintenance of axial flow fans:

1. Before installation, check in detail whether the fan is damaged or deformed due to packaging and transportation, and it can only be installed after it is properly repaired. During installation, it is necessary to check whether the connecting parts are loose, and the gap between the blades and the hair dryer should be uniform and should not be touched.

2. The weight of the pipe connecting the air outlet should not be borne by the fan duct, and additional support should be added during installation.

3. An air collector must be installed at the inlet end of the axial flow fan, and a protective wire mesh must be installed.

4. The base of the fan must be naturally connected with the foundation plane, and the bolts shall not be knocked to force the connection to prevent the base from deforming. When installing, the base should be calibrated with a level, padded to maintain its horizontal position, and then the anchor bolts should be tightened.

5. The axial flow fan is not allowed to be hoisted and used, and after the installation of the wire, it must be tested first.

6. After the ventilator has not been used for a long time, when it is reused, it is necessary to check whether the connecting parts are reliable and reliable, and can only be officially used after trial operation.

7. After the fan is officially put into operation, check whether the screws are loose and whether the wire skin is damaged once a year, and repair it according to its specific situation.

8. Always pay attention to whether there is abnormal noise in the operation of the fan, whether the vibration increases, and check and repair it in time.
