Product Description
Use condition of cooling fan:
1, the ambient temperature should be 75º C ≥ -40º C.
2. The industrial gases of the cooling fan are not allowed to have strong acids, strong bases and various solutions.
3, sand dust and other debris are not allowed to fall into the fan, so as to avoid the destruction of the fan and the fracture of the fan leaf.
Installation and maintenance of the cooling fan in this section:
1, before installation, should first check whether the damage, deformation, such as damage or deformation should be repaired and installed.
2, and then check the parts and screws are loose; between the blade and the cylinder whether a collision or shift, if encounter or shift should be adjusted before installation.
3. After the cooling fan is installed, the test machine should be carried out, and the fan should be used on line after the fan is running normally.
4. When the fan is reused for a long time, the wind turbine should be checked and tested without abnormal phenomenon, so it can be used online.
5. After the installation of the fan, the wiring should be sealed in order to prevent the connection leakage to cause the short circuit destroyed motor.
