The vibration and noise prevention of spiral air duct during installation is simply analyzed

Spiral air pipe is made of metal strip material roll spiral seam thin wall pipe, circular, no welding, no leakage, no leakage, mostly used for air supply and bulk material transport, instead of the traditional white iron pipe (that is, manual seam iron pipe). Is a type of air duct, full mechanism straight pipe without manual beating.

The prevention of vibration and noise of spiral air duct in the installation process mainly starts from the following aspects:

1. In order to prevent the vibration of spiral air duct, a fixed bracket shall be set at the corner of spiral air duct of each system and at the connection with ventilator and tuyere.

2. The spiral air duct is made, installed and connected with the components. The connection is tight and there is no air leakage phenomenon to avoid air leakage noise.

3, the fan, spiral air pipe connection using hose connection, the fan suction inlet hose installation should be done with appropriate tightness, to avoid the soft connected loose reduce the area of the inlet and outlet, and cause noise and vibration.

4. Vibration damper shall be installed according to design requirements or construction specifications.
