  在通风设备的设计、制造、安装时在以下三个方面可以避免通风设备在实际使用中出现的噪音过大的问题。

  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、降低通风设备声源噪声通风管道

  A. Reduce the sound source noise of ventilation equipment

  在噪声控制要求高的场合,应选用低噪声通风设备。不同型号的通风设备在同意的风量、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。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。设计通风系统时,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 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、传递途径上对通风设备噪声抑制

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

  在通风设备的进、出风口上装配恰当的消声器。通风设备设减振基座,进、出风口用软管连接。对通风设备做隔声处理。如设备通风设备隔声罩;在通风设备机壳内衬只声材料;将通风设备设置在专门的通风设备室内,并设置隔声门、隔声窗或设置其他吸声设施,或在通风设备室内另设值班室等。

  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、及时维护保养,定期检维护,及时更换破损零部件,排除异常,以创造低噪声运行条件。

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