摘要
压缩空气发动机是利用高压压缩空气工作,将高压空气中储存的压缩能转换其它的机械能的一种动力装置。在资源和环境问题日益突出的情况下,压缩空气发动机与传统的发动机相比具有诸多优点,因而在车辆、发电装置、航空等方面得到越来越多的应用,在国外已成为节约能源和治理环境污染的重要途径之一。国内外研究的压缩空气发动机主要有往复式、叶片式、旋转式三种结构形式。对这三类发动机的工作基本原理和结构特点进行了分析比较,得出各自的优缺点和将来研究的重点,并展望了新型旋转式压缩空气发动机技术。通过分析国内外压缩空气发动机的研究进展,从六个方面总结出提高压缩空气发动机效率和经济性的途径。
The compressed-air energy is a kind of power device for converting compressed-air energy into mechanical energy, which is using high-pressure air to work. While facing the problem of resource shortage and environmental pollution, the compressed-air engine has a lot of advantages compared with traditional engine, which has been widely used in vehicle, electrical machine, navigation and other aspects. It has become an important way to conservation and pollution control at abroad. There mainly have three forms compressed-air engine of reciprocating, vanetyped, rotary at the home and abroad. In this paper, the author analysis are on the basis of working principles and features for these three engines, which got the advantages and disadvantages and the point of research in the future, and the trend of the new rotary compressed-air engine is described. Through analysis of the compressed-air engine at home and abroad, summarizes the way to increase efficiency and economical efficiency of compressed-air engine from six different respects.
