Vibration of air duct. Because the air duct material is galvanized sheet or metal material, the steel plate thickness and construction process shall be selected strictly according to the construction inspection standard, such as air duct fabrication error, flatness and air duct reinforcement The front and back of the electric fan shall be more than 5m long as possible. Assuming that the number of elbows can be increased and the noise can be reduced, the air outlet is equipped with a filter screen, and the noise control function is also very good.

风机的动静。处理方法我们一般可装消声器处理

Dynamic and static of fan. Treatment method we can generally install muffler for treatment

风管zhong风的冲突声。一般在规划阶段就要考虑噪声的问题，规划操控好管内风速，防止风声啸叫

Duct zhongthe clash sound of the wind. Generally, the noise problem should be considered in the planning stage, and the wind speed in the pipe should be planned and controlled to prevent wind howling

1操控出风、回风间隔，防止空气对流时自激表象和小循环空间。

1. Control the air outlet and return intervals to prevent self-excited appearance and small circulation space during air convection.

2、螺旋风管风机叶轮体系动平衡校调合理正常正负不大于5丝的高低。

2. The dynamic balance adjustment of spiral duct fan impeller system is reasonable, and the positive and negative are not greater than 5 wires.

3、软接头设备标准，防止软接帆布松垮发生风阻而形成风噪。

3. Flexible joint equipment standard to prevent wind resistance and wind noise caused by loose flexible joint canvas.

4、悬挂选用趁便绷簧避震专职的连接器，减轻作业时因扭力发生的跳动或共频。

4. The suspension adopts the full-time connector of tension spring shock absorber to reduce the runout or common frequency caused by torque during operation.

5、螺旋风管风道转角尽量削减

5. The air duct corner of spiral duct shall be reduced as much as possible
