摘　　要：由于氮压机级间冷却器严重结垢,氮压机压缩气体的能力大大减小而且喘振现象频繁发生。通过对氮压机水路进行加装反冲洗阀的改造,并采用改进后的循环酸洗法对氮压机进行酸洗,从根本上解决了问题。阐述了氮压机的运行状况、改进后的循环酸洗方法及具体实施过程,介绍了氮压机级间冷却器清洗后的效果及循环酸洗阀的推广应用。The compressed gas capacity of nitrogen compressor greatly reduces owing to serious scale of nitrogen compressor interstage cooler, and surge frequently occurs. A baek-flushing valve is installed in water circuit of the nitrogen compressor and the improved cycle pickling method is used to pickle the nitrogen compressor. The above reconstruction ba sically eliminates the serious scale. The operation status of the nitrogen compressor, the im proved cycle pickling method and practical implementation process are presented. The effect of the nitrogen compressor interstage cooler and popularization and application of cycle pickling method are introduced.
