关于压缩机试车的一段句子？ 全文如下: run-in of the feed gas compressor ,102-j the ammonia compressor ,105-j and the synthesis gas compressor 103-j on will be considerably more involved if this is attempted ,because of the higher molecular weighet of the air as compared to the normal medium compressed,and because of the abnormal compression condition. if these compressors are operatedon air ,it should only be done with the advice and concurrence of the representative of the compressor manufacturer. the compressors should not be operated in a closed circuit on air and any suction openings must be properly screened to avoid the inspiration of dirt or debris. probably little or no time will be lost by arranging to operate the syn gas compressor on nitrogen ( or make gas)on total kickback within the block valves,and the refrigeration compressor on ammonia vapor introduced when the initial inventory of ammonia refrigreant is brought into the unit . conssequently,it is recommended that these items be run-in after these systems have been tightness tested and purged air free . 我的理解是:在总返回管线里面装上这些切断阀用于合成气压缩机操作(以氮气作介质或使用天然气)几乎不费多少时间.且冰机使用引入的氨蒸汽作介质,而氨冷冻系统原始开车使用氨量已送入这个系统. 翻得很累,估计我没有领会其真实的含义,请各位多多帮忙。特添加部分上下文,为红色字体.请各位继续讨论.
