摘要(Abstract)：

对定频、变频与液压3种往复活塞式压缩机在CNG子站系统中应用进行了对比分析。模拟了压缩机排气量、轴功率随吸排气压力的变化关系,得到了性能变化的曲线图。数值模拟结果与压缩机的实际运行特性表明,CNG子站用变频往复活塞式压缩机在排气量、能耗、运行时间和智能化等性能指标方面更具竞争性。
The applications of fixed-frequency reciprocating compressor,variable frequency reciprocating compressor and hydraulic reciprocating piston compressor in CNG daughter station was comparatively analyzed.Through simulating the relation of how the capacity and shaft power change along with the variation of suction pressure and discharge pressure,the graph of performance change is worked out.The numerical simulation results and actual operating characteristics of compressors indicate that the variable frequency reciprocating compressor used in CNG daughter station is more competitive in capacity,energy saving,running time and intelligence than other type compressors.
