排气量为40升/分、压力为4公斤力/厘米~2的空气压缩机是医用高速空气涡轮牙钻的心脏部件。采用偏心滚动转子式压缩机,可使牙钻整机噪声降为45～50dB(A)。本文介绍了此机的原理、结构和部分设计要点。
Air compressors with a displacement of 40 l / min and a pressure of 4 kgf / cm 2 are the heart of medical high-speed air turbine drills. Using eccentric rolling rotor compressor, the noise of the dental drill can be reduced to 45 ~ 50dB (A). This article describes the principle of the machine, structure and some of the design points.
