系统介绍了集成式压缩机的技术特点和技术优势,阐述了其在天然气管道增压、地下储气库注气和海底管道增压工程中的应用状况,展望了其在国内天然气储运领域的应用前景。该压缩机以磁悬浮轴承、高速电机和大功率变频器三大新兴技术成果为基础,将压缩机、电机、冷却系统和分离系统集成在同一加工橇架中,并作为一个整体安装使用;不含润滑油系统、密封系统,而且操作转速可以在35%～105%的范围内调节,大幅增强了其对不同操作工况的适应性;集高速、无油、整体和智能等于一身,节能环保、操作方便且性价比高,适于在长输天然气管道沿线有电力资源的地区应用。
The technical features and technical advantages of the integrated compressor are introduced systematically. The application status of the integrated compressor in natural gas pipeline pressurization, gas injection in underground storage gas reservoirs and submarine pipeline pressurization projects is expounded. The prospects of its application in natural gas storage and transportation in China Application prospects. Based on the three emerging technological achievements of magnetic bearings, high-speed motors and high-power frequency converters, the compressor integrates compressors, motors, cooling systems and separation systems in the same processing rack and is installed and used as a whole; Oil system, sealing system, and the operating speed can be adjusted within the range of 35% to 105%, greatly enhancing its adaptability to different operating conditions; set high speed, oil-free, overall and intelligent equal to one, energy saving, Easy to operate and cost-effective, suitable for use in areas with power resources along the long-distance natural gas pipeline.
