通风管道安装要点及减少噪音方法了解

来源:/     发布时间:2022-05-13  

通风管道其实是确保空气的流通,可以帮助送风机和送风口的正常运行。下面从两个方面来讲解该产品,通风管道安装要点及减少噪音方法的了解。
Ventilation duct is actually to ensure the circulation of air, which can help the normal operation of forced draft fan and air outlet. The following explains the product from two aspects, the key points of ventilation duct installation and the understanding of noise reduction methods.
在安装风管的时候,要注意一些基本的方面,为了不影响风机的正常运行,严禁其他管道通过风管。安装在易燃易爆环境中的管道要良好接地。通过生活区或生产区安装管道时,序言严格,不能安装管道接口。室外竖管不要接避雷针或避雷装置。
When installing the air duct, pay attention to some basic aspects. In order not to affect the normal operation of the fan, other pipes are strictly prohibited to pass through the air duct. Pipelines installed in flammable and explosive environment shall be well grounded. When installing pipelines through living quarters or production areas, the preamble shall be strict and pipeline interfaces shall not be installed. Do not connect the outdoor standpipe with lightning rod or lightning protection device.
管道安装要符合相关的技术规定:连接管道、通风设备和工作装置时,不要缩短连接件的连接管。喷头、风门、检查门和自动控制机构上不能安装吊架。固定在法兰上,防止管道变形影响管道功能。吊架的安装序言符合相应的安装规定。安装固定支架、支撑架等固定点,避免管道和悬空部件晃动。系统确定固定点的位置和数量。
The pipe installation shall comply with relevant technical regulations: when connecting pipes, ventilation equipment and working devices, do not shorten the connecting pipe of the connector. Hangers shall not be installed on nozzles, dampers, inspection doors and automatic control mechanisms. Fixed on the flange to prevent the deformation of the pipeline from affecting the function of the pipeline. The installation of the hanger shall comply with the corresponding installation regulations. Install fixed support, support frame and other fixed points to avoid shaking of pipes and suspended parts. The system determines the location and number of fixed points.

法兰垫片材料和厚度随输送空气温度而变化。安装通风管道及部件时,穿透墙壁和天花板时应安装防雨罩。通风管道及连接件的可拆卸,不能安装在墙壁和走道地板上。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 flange gasket material and thickness vary with the temperature of the delivered air. When installing ventilation ducts and components, rain covers shall be installed when penetrating walls and ceilings. The ventilation ducts and connectors are removable and cannot be installed on walls and walkway floors. The position of embedded parts or expansion bolts of supports, hangers and brackets shall be accurate, firm and reliable. The embedded part shall not be painted, and the oil stain shall be removed.
济南通风管道加工的不同类型的管道设备在同一的风量,风压相同机翼型叶片的离心式通风设备噪声小,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。
Different types of pipeline equipment processed in Jinan ventilation pipeline have the same air volume and pressure. The noise of centrifugal ventilation equipment with wing blades is low, and the noise of centrifugal ventilation equipment with forward plate blades is high. Low noise pipeline equipment shall be selected for occasions with high noise control requirements.
在设,建议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的时候,可将其分成为小系统;在管道内的流速不宜过快,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, it is recommended to minimize the pressure loss of the system. When the total amount and pressure loss of the ventilation system are large, it can be divided into small systems; The flow velocity in the pipeline should not be too fast to avoid causing regenerative noise. The flow velocity in the pipeline should be selected according to different requirements and relevant regulations.
合理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。
Reasonably reduce the speed of ventilation equipment. The rotating noise of the ventilation equipment is proportional to the 10th power of the circumferential speed of the impeller, and the eddy current noise is proportional to the 6th power (or 5th power) of the circumferential speed of the impeller. Therefore, reducing the speed can reduce the noise.
有大量气流进入该管道时会产生一些噪音,那如何减少其噪音便是以上的讲解内容了,如果您有问题没解决的话欢迎来网站www.1nightescorts.com进行咨询吧。
There will be some noise when a large amount of air flow enters the pipe, so how to reduce the noise is the content of the above explanation. If you have any problems that have not been solved, please visit www.1nightescorts.com Com.
