对于中央厨房设备噪音大的问题,很多朋友不知该如何解决,那么今天小编就来为大家介绍一下降低中央厨房设备源噪声的方法。
For the central kitchen equipment noise problem, many friends do not know how to solve, so today Xiaobian will introduce the method to reduce the central kitchen equipment source noise.
合理选择透风设备的机型。在噪声控制要求高的场合,应选用低噪声透风设备。不同型号的透风设备在同意的风量、风压下、机翼型叶片的离心透风设备噪声小,前向版型叶片的离心透风设备噪声大。
Reasonable selection of ventilation equipment model. Low noise ventilating equipment should be selected in the occasion with high noise control requirements. Under the agreed air volume and pressure, the noise of centrifugal ventilation equipment with wing blade is small, while that of centrifugal ventilation equipment with forward blade is large.
在可能前提下适当降低透风设备的转速。透风中央厨房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。
If possible, reduce the speed of ventilation equipment. The rotating noise of ventilation central kitchen equipment is proportional to the 10th power of impeller circumferential speed, and the eddy current noise is proportional to the 6th power (or 5th power) of impeller circumferential speed. Therefore, reducing the speed can reduce the noise.
透风设备进、出口的噪声级是透风理、风压曾加而变大。因此,设计透风系统时,应尽量减少系统的压力损失。当透风系统的总量和压力损失较大时,可将其分为小系统。
The noise level at the inlet and outlet of ventilation equipment increases with the increase of ventilation principle and wind pressure. Therefore, the pressure loss of ventilation system should be reduced as much as possible. When the total amount and pressure loss of ventilation system are large, it can be divided into small systems.

透风设备的工作点应接近效率率点。统一型号的中央厨房设备的透风设备效率越高,噪声越小。为使透风设备的运行工况点保持在透风设备的效率率区,应尽量避免用阀门进行工况调节。如需要在透风设备压出端设阀门时,其设置的位置是距透风设备出口1m处。它能使2000Hz以下的噪声降低。在透风设备进口处气流应保持平均。
The working point of ventilation equipment should be close to the efficiency point. The higher the ventilation efficiency, the lower the noise. In order to keep the operating point of ventilating equipment in the efficiency area of ventilating equipment, the valve should be avoided as far as possible. If it is necessary to set a valve at the pressing end of the ventilating equipment, the setting position is 1m away from the outlet of the ventilating equipment. It can reduce the noise below 2000 Hz. The air flow at the inlet of ventilating equipment shall be kept even.
留意透风设备与电念头的传动方式。采用直联传动的透风设备噪声小,用联轴器的次之,用没有接缝的三角皮带传动的稍差。透风设备应配用低噪声的电念头。
Pay attention to the transmission mode of ventilation equipment and motor. The ventilation equipment with direct drive has less noise than that with coupling, and that with V-belt without seam is slightly worse. Ventilating equipment shall be equipped with low noise motor.
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划定选取。
The velocity of air flow in the pipe should not be too high to avoid the regeneration noise. The velocity of air flow in the pipe should be determined according to different requirements.
以上就是关于降低中央厨房设备源噪声的方法的全部内容了,希望对大家有所帮助。
The above is about reducing the central kitchen equipment source noise method of all the content, I hope to help you.
