摘要
分析天然气调压箱的噪声问题,提出降噪解决方案。通过更换新箱体和在管道上包裹双层降噪材料,解决天然气调压箱持续供气条件下降噪问题。对比分析降噪改造前后的数据,该种方法降噪效果良好。
The noise problem of natural gas regulator box is analyzed, and a solution for noise reduetion is proposed. The noise un（ter the condition of continuous gas supply by natural gas regulator box is reduced by changing the new box body and wrapping double-layer noise reduction material on pipeline. The data before and after noise reduction reconstruction are compared and analyzed. The noise reduction effect of this method is good.
