我厂引进项目中的丫型挤出机,安装在四层楼面上.附属的两台高压离心风机,单机运转时,电动机及风机进气口的一米噪声级分别为95和100分贝(A).风机振动直接波及三楼,噪声级也为72分贝(A),使得整个四层楼面处于噪声振动之中.为解决这个
I plant imported project Ya-type extruder, installed on four floors.Analyzed two high-pressure centrifugal fan, stand-alone operation, the motor and fan inlet one meter noise levels were 95 and 100 dB ( A). Fan vibration directly affects the third floor, the noise level is also 72 dB (A), making the entire four floors in the noise vibration. To solve this
