　　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 back-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.
