　　在通風(fēng)設(shè)備的設(shè)計、制造、安裝時在以下三個方面可以避免通風(fēng)設(shè)備在實際使用中出現(xiàn)的噪音過大的問題。

　　In the design, manufacture and installation of ventilation equipment, there are three aspects to avoid the excessive noise of the ventilation equipment in practice.

　　一、降低通風(fēng)設(shè)備聲源噪聲

　　A. Reduce the sound source noise of ventilation equipment

　　在噪聲控制要求高的場合，應(yīng)選用低噪聲通風(fēng)設(shè)備。不同型號的通風(fēng)設(shè)備在同意的風(fēng)量、風(fēng)壓下、機翼型葉片的離心通風(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。適當(dāng)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。設(shè)計通風(fēng)系統(tǒng)時，應(yīng)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時，可將其分為小系統(tǒng)。氣流在管道內(nèi)的流速不宜過高，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 case of high noise control, low noise ventilation equipment should be used. With the consent of the different types of ventilation equipment in air volume, air pressure, the wing type blades of centrifugal ventilation noise, prior to version blade centrifugal ventilators large noise. Reduce the speed of ventilation equipment properly. The rotation noise of the ventilation equipment is proportional to the circle velocity of the impeller, the vortex noise is proportional to the speed of the impeller circle velocity 6 (or 5). The reduced speed can reduce the noise. When designing ventilation system, the pressure loss of the system should be minimized. When the total volume of ventilation system and the pressure loss are greater, the system can be divided into smaller systems. The flow velocity in the pipe should not be too high to cause the regeneration noise. To determine the flow velocity in the pipeline according to different requirements.

　　二、傳遞途徑上對通風(fēng)設(shè)備噪聲抑制

　　Second, the transmission path is suppressed by the noise of ventilation equipment

　　在通風(fēng)設(shè)備的進、出風(fēng)口上裝配恰當(dāng)?shù)南暺?。通風(fēng)設(shè)備設(shè)減振基座，進、出風(fēng)口用軟管連接。對通風(fēng)設(shè)備做隔聲處理。如設(shè)備通風(fēng)設(shè)備隔聲罩；在通風(fēng)設(shè)備機殼內(nèi)襯只聲材料；將通風(fēng)設(shè)備設(shè)置在專門的通風(fēng)設(shè)備室內(nèi)，并設(shè)置隔聲門、隔聲窗或設(shè)置其他吸聲設(shè)施，或在通風(fēng)設(shè)備室內(nèi)另設(shè)值班室等。

　　Assemble the appropriate silencer in the inlet and outlet of ventilation equipment. The ventilation equipment sets the base of vibration damping, and the inlet and outlet hose connection. Sound insulation for ventilation equipment. If the equipment ventilators the acoustic shield; The lining of the casing of the ventilation equipment. Set the ventilation equipment in the special ventilation equipment room, and set the soundproof door, sound insulation window or set other acoustic facilities, or setting up office in ventilation equipment room and so on.

　　三、及時維護保養(yǎng)，定期檢維護，及時更換破損零部件，排除異常，以創(chuàng)造低噪聲運行條件。

　　3, maintain maintenance in time, check and maintain regularly, replace broken parts in time, eliminate abnormal, to create low noise operating conditions.
