本文对煤矿井下用于局部通风的JBT62型轴流式风机(以下简你局扇)的噪声进行动态测试,并对噪声功率谱进行计算机数据处理和分析,找出了噪声源。为今后控制局扇噪声提供了可靠的依据和明确的方向。
In this paper, the noise of JBT62 axial fan used for local ventilation in coal mine is briefly tested. The noise power spectrum is processed and analyzed by computer, and the noise source is found out. It provides a reliable basis and a clear direction for future fan noise control.
