    通风91视频成人网站如何对抗噪音大家知道吗?

      不锈钢通风91视频成人网站的噪声及对消声91视频成人网站内衬的影响。分贝是测量每英尺的91视频成人网站长度,有内衬和无内衬的矩形91视频成人网站的各种形状和大小的山东通风91视频成人网站,以及各种频率。
      The noise of stainless steel ventilation pipe and its influence on the inner lining of silencing pipe. Decibel is the measurement of pipe length per foot, various shapes and sizes of Shandong ventilation pipes with and without lining, and various frequencies.
      衰减与吸收系数有关,吸收系数与91视频成人网站截面的大小有关,研究发现山东91视频成人网站衬砌比其他任何已经提出的公式更接近Sivian理论得出的公式。该测量还通过连接到系统的5000cfm容量风扇的噪声进行。91视频APP污发现噪音是由摩擦产生的。

      The attenuation is related to the absorption coefficient, and the absorption coefficient is related to the size of the pipeline section. It is found that the formula of Shandong pipeline lining is closer to that of sivian theory than any other formula. The measurement is also carried out by noise from a 5000 CFM capacity fan connected to the system. We found that the noise was caused by friction.
      对于高达每分钟1500英尺的速度,空气,无论是有内衬的还是没有内衬的,与91视频成人网站内壁的空气相比是微不足道的,噪音是由风扇叶片产生的。在空气阻力流动系统中引入了一种特殊的挡板结构,以测试噪声的影响。用这种方法测定了有吸收剂衬里的管子与无衬里的管子的摩擦阻力。
      For speeds up to 1500 feet per minute, air, both lined and unlined, is negligible compared to the air in the inside of the duct, and the noise is generated by the fan blades. A special baffle structure is introduced into the air resistance flow system to test the effect of noise. In this way, the friction resistance between the pipe with absorbent lining and the pipe without absorbent lining is measured.
      当通风道与外风道并列时,可采用轮式换热器。轮子的一半在一根管子里,一半在另一根管子里。
      When the ventilation channel is parallel with the external air channel, the wheel type heat exchanger can be used. Half of the wheel is in one pipe, half in the other.
      山东风道车轮转动时,位于暖道内的车轮部件对多孔车轮结构进行加热。冷却管中的车轮部分从多孔的车轮结构中去除热量。轮子也可以用干燥剂处理,这样水也可以从一个流向另一个。
      When the wheels of Shandong air duct rotate, the wheel components located in the warm channel heat the porous wheel structure. The wheel part of the cooling pipe removes heat from the porous wheel structure. Wheels can also be treated with desiccant so that water can flow from one to the other.
      车轮没有完全密封,车轮本身的体积从一个91视频成人网站泄漏到另一个。因此,需要在流之间零转移(交叉污染)的应用程序不能使用轮子。车轮需要并排和相同大小的91视频成人网站,限制了许多应用程序所需的打包自由。但并非更不重要的是,轮子是带有马达、皮带、滑轮、轴承等的主动移动机器,需要高度熟练的维修人员来保持轮子转动。
      The wheels are not completely sealed and the volume of the wheels themselves leaks from one pipe to another. Therefore, applications that require zero transfer (cross contamination) between flows cannot use wheels. Wheels require side-by-side and the same size of pipes, limiting the freedom of packaging required by many applications. Last but not least, the wheel is an active moving machine with motor, belt, pulley, bearing, etc., which requires highly skilled maintenance personnel to keep the wheel rotating.
