摘　　要：氮气充装系统是获得高纯氮气的有效途径,应用广泛,氮气机械化充装系统是必然趋势。介绍了氮气充装系统及其数学模型假设,基于范德瓦尔方程数值模拟了在氮气瓶组充气过程中充装系统的动态特性,建立了充装系统的充气过程数学仿真模型。工程模拟仿真估算出了不同气源压力下充气过程中氮气瓶组比体积、压力及温度的动态变化,可为实现氮气机械化充装提供理论依据。Nitrogen filling systems which is widely used is an effective access to high purity nitrogen,nitrogen filling system mechanization is an inevitable trend. Simulation system dynamic characteristic is based on Van der Waals equation in filling nitrogen cylinders during inflation, aiming to the establishment of a system of pneumatic filling process mathematical simulation models. Further, under different gas source pressure, dynamic changes of specific volume, pressure and temperature is estimated to achieve the feasibility of nitrogen filling system mechanization.
