Key points for construction and installation of pipeline ventilation fans

Pipe ventilation fanKey points of construction and installation

1. Pipe ventilation fanThe installation pedestal (foundation, hanger) should have sufficient strength, stability, and durability, and the vibration of the pedestal should meet the following requirements:

1) The natural frequency of the basic device shall not exceed one-third of the speed of the motor and ventilation fan;

2）Pipe ventilation fanThe difference between the vibration speed during operation and the vibration speed when the ventilation fan is stationary should be greater than three times.

　　2. Pipe ventilation fanFlexible joints should be installed for the connection between imports and exports and air ducts. The inlet and outlet ducts and other devices should be separately supported and firmly supported by foundations or other building components. The casing should not bear the weight of other components.

　　3. Pipe ventilation fanWhen installed on building components, vibration isolation measures should be taken.

　　4. Pipe ventilation fanInstallation can refer to the following national building standard design drawings.

　 5.Pipe ventilation fanCan be installed on straight air ducts, with the advantages of easy connection and small space occupation.
