一、噪音来源于

1、 The noise comes from

通风管道管理体系工作噪音一般来自下列好多个层面:

The working noise of ventilation pipe management system generally comes from the following levels:

1、通风风管的晃动。由于通风风管原材料是镀锌钢板或是是金属复合材料，在工程施工时要不容乐观依照工程施工检验标准挑选不锈钢厚度和施工技术，例如风管制作错漏、竖直度、通风风管结构加固、抗震支架挑选及制做机器设备这些。到工程施工环节，通风口尽可能不必靠近机器设备。电风扇前后左右尽可能都是有5米之上的长短。假设能够提升弯管数量还可以降低噪音，出风口改装滤网，噪音操纵功效也很好。

1. Shaking of ventilation duct. As the raw material of ventilation air duct is galvanized steel sheet or metal composite material, it is not optimistic during project construction. Stainless steel thickness and construction technology shall be selected according to the project construction inspection standards, such as air duct fabrication error and leakage, verticality, ventilation air duct structure reinforcement, seismic support selection and manufacturing machinery and equipment. During the construction phase, the vent shall not be close to the machinery and equipment as much as possible. As far as possible, the electric fan is more than 5 meters long. Assuming that the number of bends can be increased and the noise can be reduced, the filter screen is modified at the air outlet, and the noise control effect is also very good.

2、离心风机的声响。解决方式 大家一般能装消音器解决通风风管脑中风的矛盾声。

2. Sound of centrifugal fan. Solution: we can generally install silencers to solve the contradictory sound of cerebral apoplexy in ventilation ducts.

二、生产制造操纵

2、 Manufacturing manipulation

一般在生产制造环节就需要考虑到噪音的难题，整体规划操纵好管中风力，避免声响噪音。

Generally, the noise problem needs to be considered in the production and manufacturing process, and the wind force in the pipe shall be well planned and controlled to avoid noise.

1、操纵进风口、送风间距，避免空气对流时自激振荡现象和小循环系统室内空间。

1. Operate the air inlet and air supply spacing to avoid self-excited oscillation during air convection and indoor space of small circulation system.

2、螺旋风管离心叶轮管理体系转子动平衡校调有效一切正常正负极不超5丝的高矮。

2. The spiral duct centrifugal impeller management system can effectively adjust the rotor dynamic balance, and the height of all normal positive and negative poles does not exceed 5 wires.

3、软接设备标准，避免软接白帆布松驰产生空气阻力而产生车噪。

3. The flexible connection equipment is standard to avoid the vehicle noise caused by the air resistance caused by the relaxation of the soft connection white canvas.

4、悬架采用趁便绷簧减震职业的射频连接器，缓解工作时易扭矩产生的颤动或共频。

4. The suspension adopts the radio frequency connector that takes advantage of the tension spring to reduce the vibration or common frequency caused by torque during operation.

5、螺旋风管风管拐角尽可能减少。

5. Spiral duct corners shall be minimized.

三、安裝全过程中的防止

3、 Prevention during the whole installation process

通风管道安裝全过程中震动和噪音的防止关键从下列好多个层面下手：

The key to prevent vibration and noise during the whole process of ventilation pipe installation is from the following aspects:

1、离心风机安裝时按设计方案规定或施工工艺规定，设定减震设备。

1. During the installation of centrifugal fan, damping equipment shall be set according to the provisions of design scheme or construction process.

2、为避免螺旋风管震动，在每一个系统软件螺旋风管的拐弯处、与排风机和出风口的相接处设支撑架。

2. In order to avoid the vibration of spiral air duct, support frame shall be set at the corner of spiral air duct of each system software and the connection with exhaust fan and air outlet.

3、离心风机、螺旋风管相互连接选用塑料软管联接，离心风机吸入口的塑料软管安裝要保证紧松适当，防止因软接到松减少进通风口总面积，而造成噪音和震动。

3. The centrifugal fan and spiral air duct shall be connected with each other by plastic hose. The plastic hose at the suction inlet of the centrifugal fan shall be properly tightened and loosened to prevent noise and vibration caused by reducing the total area of the air inlet due to loose connection.

4、螺旋风管安裝及与构件联接，联接严实 ，无透风状况，以防造成透风噪音。

4. Spiral air duct shall be installed and connected with components tightly without ventilation to prevent ventilation noise.
