本文介绍了Atlas Copco公司开发的小型单齿双转子无油压缩机的工作原理、设计与结构及其性能分析。该压缩机具有空载功率较小,(小于满载功率的20%);结构简单,成本较低;无轴向力,使用可靠,寿命长特别适用于长期连续运行的小流量场合。 This article presents the working principle, design, structure and performance analysis of a small, single tooth, two-rotor, oil-free compressor developed by Atlas Copco. The compressor has a small no-load power, (less than 20% of full load power); simple structure, low cost; no axial force, reliable use and long life especially suitable for long-term continuous operation of small flow applications.
