通風管道其實是確?？諝獾牧魍?，可以幫助送風機和送風口的正常運行。下面從兩個方面來講解該產品，通風管道安裝要點及減少噪音方法的了解。
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.
在安裝風管的時候，要注意一些基本的方面，為了不影響風機的正常運行，嚴禁其他管道通過風管。安裝在易燃易爆環(huán)境中的管道要良好接地。通過生活區(qū)或生產區(qū)安裝管道時，序言嚴格，不能安裝管道接口。室外豎管不要接避雷針或避雷裝置。
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.
管道安裝要符合相關的技術規(guī)定：連接管道、通風設備和工作裝置時，不要縮短連接件的連接管。噴頭、風門、檢查門和自動控制機構上不能安裝吊架。固定在法蘭上，防止管道變形影響管道功能。吊架的安裝序言符合相應的安裝規(guī)定。安裝固定支架、支撐架等固定點，避免管道和懸空部件晃動。系統(tǒng)確定固定點的位置和數量。
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.
法蘭墊片材料和厚度隨輸送空氣溫度而變化。安裝通風管道及部件時，穿透墻壁和天花板時應安裝防雨罩。通風管道及連接件的可拆卸，不能安裝在墻壁和走道地板上。支、吊、托架的預埋件或膨脹螺栓，位置應準確、牢固可靠，埋入部分不得油漆，并應支除油污。
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.
濟南通風管道加工的不同類型的管道設備在同一的風量，風壓相同機翼型葉片的離心式通風設備噪聲小，前向版型葉片的離心通風設備噪聲大。在噪聲控制要求高的場合，應選用低噪聲管道設備。
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.
在設，建議盡量減少系統(tǒng)的壓力損失。當通風系統(tǒng)的總量和壓力損失較大的時候，可將其分成為小系統(tǒng)；在管道內的流速不宜過快，以免引起再生噪聲，確定管道內氣流流速應根據不同要求按有關規(guī)定選取。
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.
合理降低通風設備的轉速。通風設備的旋轉噪聲與葉輪圓周速度10次方成比例，渦流噪聲與葉輪圓周速度6次方(或5次方)成比例，故降低轉速可降低噪聲。
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.
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 m.yiruizhoucheng.com Com.
