[摘要]：针对关国Ariel天然气压缩机对槽车加气过程中的最终排气压力，瞬时功率，加气量，压缩机运行时间之间的变化，基于实时记录的数据，通过计算机软件对数据进行曲线拟合，找出与数据点最吻合的拟合曲线，并得出拟合曲线经验公式；基于时间与辟时功率的曲线图通过数学方法求其时间上的面积积分，即整个加气过程中的消耗功，从而得出理论能耗数值。通过得出的经验公式指导在对槽车加气过程中，对压缩机最终排气压力达到某一值和加气量达到某一值所需时间的预估，从而帮助估算压缩机的停机时间和槽车加满气的时问，以及压缩机工作过程中的最终排气压力达到某一值时对应的瞬时功率值，进而帮助判断压缩机是否出现故障。

Abstract:This paper aims to analyze the data during Ariel natural gas compressor aerated for tankers, references to final exhaust pressure, instantaneous power, plus gas and compressor running time, Based on realtime recording, computer software for curve fit ting the data points to find the best fit curve fitting and obtain fitting curve empirical fommula, Based on the time and the instanta-neous power demand curve, mathematical methods are used for integrating the area on their time that the whole process of flling the power consumption to derive the theoretical energy value. Thus by the obtained formula it can predict when gas compressor's final delivery pressure and adding gas quantity reach a certain value during tanker's flling gas process, then it could estimate the time that gas compressor's shutting down and the tanker was filled full gas, at the same time, it also could predict the instantaneous power value when gas compressor's final delivery pressure reaches a certain value, further help determine whether compressor occurs any fault.
Key words: natural gas compressors; final discharge pressure; instantaneous power, curve fitting; theoretical energy
