Through redesigning of pipe system to alter its character and using the ways to isolate vibration and reduce vibration, it is yielded very good results of reducing the vibration and noise. in some points the acoustic pressure level drops very much, such as in the standard point of number one pump the acoustic pressure level drops 15db ( a ) and in the standard point of cistern also drops 15db ( a ), and in the highest point of the acoustic pressure before redesign drops from 105db ( a ) to 44db ( a ), and in the second floor the acoustic pressure level have reached the requirment
通過對管道結構的改造,減振和隔振措施的有效使用,使供水系統的振動和噪聲得到了有效的控制:使一號泵前的標準點和蓄水池前標準點的噪聲聲壓級都降低了15db ( a ) ,管道上測點的振動量降低了90 ;二樓居民門外的噪聲從55db ( a )降到25db ( a ) ,遠低國家標準35db ( a ) ;在改造前噪聲最大點西側蓄水池的噪聲也由105db ( a )降到44db ( a ) 。
