本文论述容积式压缩机中有代表性的螺杆式压缩机和往复式压缩机的噪声问题。 一、螺杆式压缩机噪声 1.螺杆式压缩机的行程容积 螺杆式压缩机是双轴回转式压缩机的一种当相互向相反方向扭转的转子啮合回转时,以机壳包围的齿槽的容积在脱离啮合一侧增加,在进入啮合一侧减少。转子有阴阳两种,齿的组合有3+4、4+5、4+6、6+8数种。 螺杆式压缩机图1所示阳转子齿槽A1及阴转子齿槽B1的面积乘以转子长度L的容积,阳转子每一转时只吸进半周的气量。因此行程容积是
This article addresses the noise issues typical of screw compressors and reciprocating compressors in positive displacement compressors. First, the screw compressor noise 1. Screw compressor stroke volume Screw compressor is a two-shaft rotary compressor when the rotor in the opposite direction to reverse rotation of the meshing back to the case surrounded by the alveolar The volume increases on the side of disengagement and decreases on the side of engagement. The rotor has two kinds of yin and yang, the combination of teeth have 3 +4,4 +5,4 +6,6 +8 several species. The area of the male rotor alveolus A1 and the female rotor alveolus B1 shown in FIG. 1 of the screw compressor is multiplied by the volume of the rotor length L, and the male rotor sucks only the gas of half a week for each revolution. So the travel volume is
