噪声治理措施 Noise control measures

机房噪音治理Noise control in computer room

1. 在风机进出口管道上安装消声器 
1. In the fan inlet and outlet pipeline installed muffler

2. 在风机机组外加装隔声罩
2. In the fan unit with sound insulation cover

3.采取改造风机机房的综合治理措施 The transformation of the fan room to take comprehensive measures

 如果有专门的风机机房，则可结合现场情况采取将风机机房改造成隔声间的降噪方法，即把风机机组封闭在机房内使其噪声传不出去，这样机房内的噪声虽大，但外界噪声则小多了。密封的机房上要设置进、排风系统，同时配套消声装置，以供通风机吸气和电动机、机壳等散热之需要。

 If there is a wind machine room specially, can be combined with the site conditions will be taken into the room sound insulation noise reduction method for transformation of fan, the fan unit is closed to make the noise came out in the room, so the noise inside the room is great, but the outside noise is much smaller. The sealed room should be equipped with the air inlet and exhaust system, and at the same time, the muffler device can be used to provide the ventilation and the heat dissipation of the motor and the casing.

4、噪声控制要求较高时，则须要同时采取减振、基础隔振、吸声和隔声等多种措施综合治理机组的机械噪声、振动和电磁噪声，以便得到满意的降噪效果。

Noise control is required, will be taken at the same time, the foundation vibration isolation, sound absorption and sound insulation and other measures for the comprehensive treatment unit of mechanical noise, vibration and electromagnetic noise, so as to be satisfied with the results of reduction.
