机械真空泵由于机械振动等原因产生一种使人烦噪的、讨厌的、不需要的声音,这就是噪声。影响机械真空泵噪声的因素很多,这里仅谈谈除泵以外电机、环境等因素对泵噪声测定的影响。噪声的大小、危害程度以及对周围环境的污染,用什么方法来评定呢?根据噪声源的频谱特性和不同的目 Mechanical vacuum pump and other reasons due to mechanical noise annoying, annoying, unwanted sound, which is noise. There are many factors that affect the mechanical vacuum pump noise, here only to talk about the pump, motor, environment and other factors on the determination of the impact of the pump noise. The size of the noise, the degree of harm and the pollution of the surrounding environment, what method to assess it? According to the noise spectrum characteristics and different head
