【澳门葡萄京官方网站】控制噪音的措施都有哪些?

发布人:   发布时间:2020-02-17 16:18:35

  在噪声控制要求高的情况下,应选择低噪声的通风管道设备。不同类型的通风管道设备在风量、风压相同的情况下,叶片的离心式通风设备噪声较小,叶片的前向版本的离心式通风设备噪声较大。适当降低通风设备的速度。通风设备的旋转噪声与叶轮圆周速度的10次方成正比,涡流噪声与叶轮圆周速度的6次方(或5次方)成正比。因此,降低速度可以降低噪音。
  In the case of high noise control requirements, low noise ventilation pipe equipment should be selected. In the case of the same air volume and air pressure, the centrifugal ventilation equipment with different types of ventilation pipe equipment has less noise, and the forward version of the centrifugal ventilation equipment with blades has more noise. Reduce the speed of ventilation equipment properly. The rotating noise of the ventilation equipment is directly proportional to the 10th power of the peripheral speed of the impeller, and the eddy noise is directly proportional to the 6th power (or 5th power) of the peripheral speed of the impeller. Therefore, reducing the speed can reduce the noise.
  在设计通风系统时,应尽量减少系统的压力损失。当通风系统的总容积和压力损失较大时,可分为小系统。管道内气流速度不宜过高,以免造成再生噪声。确定管道内的流速应根据不同要求,按有关规定进行选择。
  When designing the ventilation system, the pressure loss of the system should be minimized. When the total volume and pressure loss of ventilation system is large, it can be divided into small systems. The air velocity in the pipeline should not be too high to avoid regeneration noise. The flow rate in the pipeline shall be determined according to different requirements and relevant regulations.
  通风管道是一种使空气流通,降低有害气体浓度的市政基础设施。它也是目前工厂车间的主要冷却方式。使用通风管道降温时应注意哪些细节?
  Ventilation pipe is a kind of municipal infrastructure which can make the air circulate and reduce the concentration of harmful gases. It is also the main cooling mode in the factory. What details should be paid attention to when using ventilation pipe to cool down?
  首先,深呼吸,沉着下来。由于建筑、机械设备、人体等热源的影响,需要通风的地方气温高于室外。负压风机能迅速排出室内热空气,使室内温度与室外温度一致,不使车间温度升高。

  First, take a deep breath and calm down. Due to the influence of heat sources such as buildings, mechanical equipment, human body, etc., the air temperature in the place requiring ventilation is higher than that outside. The negative pressure fan can quickly discharge the indoor hot air, so that the indoor temperature is consistent with the outdoor temperature, and the workshop temperature will not rise.
  第二,空气的流动带走了身体的热量。空气的流动加速了汗水的蒸发,吸取了身体的热量,使身体感到凉爽,就像自然风一样凉爽。
  Second, the flow of air takes away heat from the body. The flow of air accelerates the evaporation of sweat, absorbs the heat of the body, and makes the body feel cool, just like the natural wind.
  第三,负压风机只有通风降温作用,没有制冷功能,降温是人体的感觉。说一台负压风扇能下降多少温度是无知的。
  Third, the negative pressure fan only has the function of ventilation and cooling, and has no cooling function. Cooling is the feeling of human body. It is ignorant to say how much temperature a negative pressure fan can reduce.
  第四,整个通风项目需要配合水幕的使用,夏季时车间温度最高可控制在28摄氏度以内。但人体的凉感可与空调相比,对水幕的人会感到稍长一点的冷而无法忍受。
  Fourth, the whole ventilation project needs to cooperate with the use of water curtain. In summer, the maximum workshop temperature can be controlled within 28 ℃. But the human body's cool feeling can be compared with that of air conditioning, and people with water curtain will feel a little longer cold and can't stand it.
