我们对油封机械真空泵泵部份的主要噪声源──“油锤效应”进行了实验验证与分析。应用研究结论对国产2X-4泵进行降噪研究,使泵的噪声从Lw=78dB(A)降低到Lw=63.8dB(A).
We have the oil seal mechanical vacuum pump part of the main noise source ─ ─ “oil hammer effect” was experimentally verified and analyzed. Applying the conclusions of the study, the noise reduction of 2X-4 pump made in our country was studied, and the pump noise was reduced from Lw = 78dB (A) to Lw = 63.8dB (A).
