Jinan ventilation pipe must be familiar to everyone, it is actually to ensure the circulation of air, but when a large number of air flow into the pipe will produce some noise, so how to reduce the noise? Do you know? Is not very clear? Next, follow the Jinan air pipe processing factory to understand it, hope to help you.

济南通风管道

Jinan ventilation pipe

管道加工的不同型号的管道设备在同一的风量、风压下、机翼型叶片的离心通风设备噪声小，前向版型叶片的离心通风设备噪声大。在噪声控制要求高的场合，应选用低噪声管道设备。

Under the same air volume and pressure, the noise of centrifugal ventilation equipment with wing blade is small, while that with forward blade is large. Low noise pipeline equipment should be selected in the situation of high noise control requirements.

在设计通风系统时，济南通风管道加工厂建议应尽量减少系统的压力损失。当通风系统的总量和压力损失较大时，可将其分为小系统;气流在管道内的流速不宜过高，以免引起再生噪声。确定管道内气流流速应根据不同要求按有关规定选取。

In the design of ventilation system, Jinan ventilation pipeline processing plant suggests that the pressure loss of the system should be reduced as much as possible. When the total amount and pressure loss of the ventilation system are large, it can be divided into small systems; the velocity of the air flow in the pipeline should not be too high, so as not to cause regeneration noise. The velocity of air flow in the pipe should be selected according to different requirements and relevant regulations.

管道和配件可拆卸的接口，不得装设在墙和走道楼板内。支、吊、托架的预埋件或膨胀螺栓，位置应准确、牢固可靠，埋入部分不得油漆，并应支除油污。

The detachable joints of pipes and fittings shall not be installed in the wall and corridor floor. The position of embedded parts or expansion bolts of supports, hangers and brackets shall be accurate, firm and reliable. The embedded parts shall not be painted and shall be supported for oil removal.

适当降低通风设备的转速。通风设备的旋转噪声与叶轮圆周速度10次方成比例，涡流噪声与叶轮圆周速度6次方(或5次方)成比例，故降低转速可降低噪声

Properly reduce the speed of ventilation equipment. The rotating noise of ventilation equipment is proportional to the 10th power of impeller circumferential speed, and the vortex noise is proportional to the 6th power (or 5th power) of impeller circumferential speed, so reducing the rotating speed can reduce the noise

水平安装：风管直径或大边长小于40mm，间距<=4m;大于或等于400mm，则间距≤3m。垂直安装：间距<=4m但每根立管的固定件应大于等于2个。

Horizontal installation: if the diameter or major side length of air duct is less than 40mm, the spacing is less than or equal to 4m; if it is greater than or equal to 400mm, the spacing is less than or equal to 3m. Vertical installation: the spacing is less than or equal to 4m, but the number of fixings for each riser shall be greater than or equal to 2.

风管的阀类调节部门应安装在便于操作的部位，阀板应顺气流方向插入，防火阀安装位置应正确，易熔件应在系统安装后装入。各类风口安装应平整，位置准确。转运部分应灵活，与风管连接应牢固。柔性短管安装松紧适当，不得扭曲。

The valve regulating Department of the air duct shall be installed at the position convenient for operation, the valve plate shall be inserted along the air flow direction, the installation position of the fire damper shall be correct, and the fusible parts shall be installed after the system is installed. The installation of all kinds of air outlets should be smooth and accurate. The transfer part shall be flexible and firmly connected with the air duct. The flexible short pipe shall be installed with proper tightness without distortion.
