通風(fēng)管道其實(shí)是確保空氣的流通，可以幫助送風(fēng)機(jī)和送風(fēng)口的正常運(yùn)行。下面從兩個(gè)方面來講解該產(chǎn)品，通風(fēng)管道安裝要點(diǎn)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(fēng)管的時(shí)候，要注意一些基本的方面，為了不影響風(fēng)機(jī)的正常運(yùn)行，嚴(yán)禁其他管道通過風(fēng)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(chǎn)區(qū)安裝管道時(shí)，序言嚴(yán)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(guān)的技術(shù)規(guī)定：連接管道、通風(fēng)設(shè)備和工作裝置時(shí)，不要縮短連接件的連接管。噴頭、風(fēng)門、檢查門和自動(dòng)控制機(jī)構(gòu)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(yīng)的安裝規(guī)定。安裝固定支架、支撐架等固定點(diǎn)，避免管道和懸空部件晃動(dòng)。系統(tǒng)確定固定點(diǎn)的位置和數(shù)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(fēng)管道及部件時(shí)，穿透墻壁和天花板時(shí)應(yīng)安裝防雨罩。通風(fēng)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(yù)埋件或膨脹螺栓，位置應(yīng)準(zhǔn)確、牢固可靠，埋入部分不得油漆，并應(yīng)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(jì)南通風(fēng)管道加工的不同類型的管道設(shè)備在同一的風(fēng)量，風(fēng)壓相同機(jī)翼型葉片的離心式通風(fēng)設(shè)備噪聲小，前向版型葉片的離心通風(fēng)設(shè)備噪聲大。在噪聲控制要求高的場(chǎng)合，應(yīng)選用低噪聲管道設(shè)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(shè)，建議盡量減少系統(tǒng)的壓力損失。當(dāng)通風(fēng)系統(tǒng)的總量和壓力損失較大的時(shí)候，可將其分成為小系統(tǒng)；在管道內(nèi)的流速不宜過快，以免引起再生噪聲，確定管道內(nèi)氣流流速應(yīng)根據(jù)不同要求按有關(guān)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(fēng)設(shè)備的轉(zhuǎn)速。通風(fēng)設(shè)備的旋轉(zhuǎn)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(zhuǎn)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.

有大量氣流進(jìn)入該管道時(shí)會(huì)產(chǎn)生一些噪音，那如何減少其噪音便是以上的講解內(nèi)容了，如果您有問題沒解決的話歡迎來網(wǎng)站www.pvcbox.cn進(jìn)行咨詢吧。
