摘要
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）．
Abstract We have carried out the testing and analysis of the main noise cause hydraulic knocking-of the pump body of the oil-sealed mechanical vacuum pump.The research result is also used to reduce the noise of Z×-4 pump. Thetotal pump noise level was reduced from Lw=78dB (A) to Lw=63.8dB (A) bythe effective measures taken.
