双螺杆空气压缩机设计.docVIP

摘要 双螺杆压缩机是一种比较新颖的压缩机，因其可靠性高、操作维修方便、动力平衡性好、适应性强等优点而广泛地应用于矿山、化工、动力、冶金、建筑、机械、制冷等工业部门。双螺杆压缩机已经超过所有工业压缩机的50 ％，其市场份额超过80 ％，今后其市场份额还将继续扩大。双螺杆压缩机可分为喷油螺杆空气压缩机、喷油螺杆制冷压缩机、喷油螺杆工艺压缩机、干式螺杆压缩机、喷水螺杆压缩机和其他螺杆机械装置。 由于油分离和气体净化技术的发展，喷油式螺杆压缩机越来越多地被用到对空气品质要求非常高的场合，如食品、医药及棉纺企业，占据了许多原属无油压缩机的领域喷油螺杆空气压缩机 Abstract double screw compressor is a kind of is new compressor, because of its high reliability, convenient operation and maintenance, good dynamic balance, the advantages of high adaptability and widely used in mining, chemical, power, metallurgy, construction, machinery, refrigeration and other industrial sectors. Double screw compressor has more than 50% of all industrial compressor, the market share of more than 80%, its share of the market will continue to expand in the future. Double screw compressor can be divided into the injection screw air compressor, injection screw refrigeration compressor, oil injection screw compressor, dry type screw compressor, screw compressor and other screw mechanism. thanks to the development of oil separation and purification technology of gas injection type screw compressor is increasingly used for air quality requirement is very high, such as food, medicine and cotton spinning enterprise, occupy a lot of the original belongs to the field of oil free compressor. Visible, research is of great significance to double screw compressor. This topic is mainly the design general spray double screw air compressor, the unilateral asymmetric cycloid - pin tooth line of circular arc type, Yin and Yang rotor gear ratio of 6:4. Design a new type rotor line, the purpose is to make the contact line length, leakage and seal clearance volume 3 triangle area is to achieve optimal design, in order to further improve the mechanical performance of double screw compressor. Focus is the study of the double screw compressor rotor profile design, geometric characteristics, stress analysis, thermodynamic calculation. Key words: injection type twin-screw air compressor rotor wi
