| 摘 要： | 防爆抽出式风机的噪声是空气动力性噪声、电动机噪声、风机机械性噪声、扩散器出口噪声等相互叠加的结果。对电机房和风机房的噪声分别采取隔声处理与加装吸声体相结合的方法降噪，取得了较好的降噪效果，综合声级达到环保要求，厂界噪声夜问实测低于50dB(A)。

| Abstract: | Noises from anti-explosion extraction fans in a combination of the air dynamic noises, the motor noises, the mechanical noises from fan and the noises from the diffuser exits. By integrating the sound insulation treatment and the installation of sound absorbers for the noises from the electronic motor house and the anti-explosion extraction fan house, good results of reducing noises have been obtained, with the composite sound level meeting the demands of environmental protection and the measured factory noises at night under the level of 50dB. |
