FRP negative pressure fan roof installation precautions

1. Before installation, check the fan for damage and deformation due to packaging and transportation, and install it only after it is repaired properly. When installing, pay attention to check whether the related parts are loose, and the gap between the blade and the wind cylinder should be even, and they should not touch each other.
2. The weight of the pipe connected to the air outlet should not be borne by the fan, and additional support should be provided during installation.
3. A wind collector should be installed at the end of the axial flow fan, and the protective barbed wire should be installed.
4. The fan base must be naturally connected with the ground plane, and the bolts must not be forced to connect to prevent the base from deforming. When installing, use a spirit level to correct the machine base, add pads to maintain its horizontal position, and then tighten the anchor bolts.
5. This shaft circulation fan is not allowed to be hoisted. After installation, it will be tested scientifically.
6. When the ventilator is not used for a long time, when it is re-used, first check whether the connecting parts are firm and reliable, and after trial operation, it can be officially used.
7. After the fan is officially operated, check once a year whether the screws are loose and the wire skin is damaged, and repair it according to its specific conditions.
8. Always pay attention to whether there is abnormal noise or increased vibration during operation of the fan, and check and repair in time.
