1. When installing the fan, a comprehensive inspection of all components should be carried out to ensure that the parts are complete and the connections between each component are secure.

2. When installing the fan, attention should be paid to maintaining the horizontal position of the fan. The joint surface between the fan and the foundation, as well as the connection of the air outlet duct, should be adjusted to be natural and fitting, and there should be no forced connection. It is not allowed to add the weight of the duct to the components of the fan.

3. If any abnormal phenomena such as severe vibration or impact are found during the operation of the fan, it must be stopped immediately for inspection.

4. There are two types of air intake for mixed flow fans, one is secondary air intake with natural air, and the other is air supply through fresh air ducts.

5. Wind turbines should be equipped with rain protection measures when used outdoors.

Analysis of common faults in fans: There are many reasons for fan vibration, which can be checked from the following aspects:

①. The impeller rubs against the air duct and produces abnormal sounds and vibrations

②. The bracket foot bolts are not tightened, which can also cause significant vibration

③. The impeller vibrates due to deformation caused by hand pressure or loosening of bolts during transportation

④. Loose connection screw between blade and shaft sleeve, flexible spindle bending and deformation

⑤. Loose screws connecting the bracket to the motor cause blade imbalance and bearing damage, resulting in intense vibration.
