Design considerations of sound insulation cover for dust removal equipment
The sound insulation cover of the dust removal equipment has the effect of sound insulation and reduction of noise generated during the operation of the equipment. The design considerations of the sound insulation cover of the dust removal equipment are divided into the following points:
根据 除尘器设备的噪声声源特征和噪声的辐射大小，确定除尘设备隔声罩的隔声量。 1: According to the characteristics of the noise source of the dust collector equipment and the radiation level of the noise, determine the sound insulation of the sound insulation cover of the dust collector equipment. According to the determined sound insulation volume, through designing sound insulation materials and sound absorption processing methods that can meet the requirements of sound insulation volume. The material design of the sound insulation cover of the dust collector equipment has a sufficient amount of sound insulation effect. When selecting the material, the density should be high, and the thickness of the sound insulation material must not be too thin.
根据噪声 的声源的形体，首先确定隔声罩的外形尺寸。 2: According to the shape of the noise source, first determine the external dimensions of the sound insulation cover. Also count the natural vibration and frequency of the sound insulation cover of the dust removal equipment. If the natural frequency of the sound insulation cover of the dust removal equipment is small, you can replace the outer size of the sound insulation cover or increase the thickness of the selected material.
3: The opening of the sound insulation cover of the dust collector equipment should be counted several times, and the resonance frequency of the sound insulation cover is controlled, and a small value is good.
隔声罩的 里面的表面要作除声设计，除声系数应该设计的大些。 4: The inner surface of the sound insulation cover should be designed for sound elimination, and the sound elimination coefficient should be designed to be larger. Generally, when designing a steel plate sound insulation cover, a layer of ultra-fine glass wool with a high sound absorption coefficient is closely attached to the inner wall of the cover to improve or improve the sound insulation performance of the steel plate.
为 了不让隔声罩壁内因受到很高的噪声声源激发而共振，内壁面与除尘器设备的空间距离不能低过1。 5: In order not to cause resonance in the sound insulation hood wall due to the excitation of a very high noise source, the space distance between the inner wall surface and the dust collector equipment must not be lower than 1.
6: The sound insulation hood of the dust removal equipment should not be designed to be too heavy, so as to be inconvenient during installation. How to use a thin metal plate should be designed with a damping layer.
厂家在设计除尘设备隔声罩的时候，一定要保证车间室内空气流通和温度相宜！ In the end, when designing the dust cover of the dust removal equipment manufacturers , they must ensure that the indoor air circulation and temperature in the workshop are appropriate!
