摘要
柴油发电机组噪声强 ,发热量大。通过对柴油发电机组提出隔声、消声、减振、通风散热的具体措施后 ,经工程实践证明 ,方案设计合理 ,达到预期的降噪效果 ,昼间等效声级 <6 0dB(A) ,夜间等效声级 <5 0dB(A) ,符合GB12 348
The noise and heat of generator are very strong In this article, properties of generator noise sound insulation, noise elimination, damping and ventilation cooling are discussed Project practice shows that, the design is reasonable, and desired results are already achieved, day noise<60 dB(A),night noise<50 dB(A), the design can meet the national secondary discharge standard of GB12348 90.
