随着国内经济的快速发展,科学技术的不断进步,国内城市各项基础设施建设的进程加快,国家对加气站稳定、持续发展也给予高度重视。压缩机是CNG加气站的主要耗能单元,由于国家对CNG技术进行有效的分析、研究的时间略短于西方发达国家,因此,导致CNG加气站的工艺以及节能技术都不太成熟,再加上CNG压缩机整体性能不够强,致使系统运行的过程中,经常出现能耗较高、效率低的问题,逐渐成为国家油气管理部门和社会科研学者关注的焦点之一。如何提高CNG压缩机效率,降低能耗是国家经济发展的基石。
With the rapid development of the domestic economy and the continuous improvement of science and technology, the process of infrastructure construction in domestic cities has been accelerated. The state has also attached great importance to the stability and sustainable development of gas station. Compressor is the main energy-consuming unit of CNG refueling station. Due to the effective analysis of CNG technology by the state, the research time is slightly shorter than that of western developed countries. Therefore, the technology of CNG refueling station and the energy-saving technologies are not mature enough, Coupled with the CNG compressor overall performance is not strong enough, resulting in the operation of the system, often high energy consumption, low efficiency, and gradually become the national oil and gas management and social science scholars one of the focuses of attention. How to improve CNG compressor efficiency and reduce energy consumption is the cornerstone of the country’s economic development.
