柴油加氢精制装置新氢压缩机故障分析及对策

Fault Analysis of New Hydrogen Compressor in Diesel Hydrofining Unit and the Countermeasures

新氢压缩机组是加氢装置中的核心设备,其运动部件多,易发生故障。文章简要介绍了1.60Mt/a柴油加氢精制装置新氢压缩机组的基本情况,针对当前该机组在运行过程中出现的二级负荷异常故障、电机轴瓦烧损、HydroCOM系统故障等问题进行分析,并结合历次检修经验,找出故障原因,提出改进措施,取得了良好的效果,为同类装置往复式压缩机的长周期运行提供了宝贵经验。

The new hydrogen compressor unit is the core equipment in the hydrogenation unit. It has many moving parts, which is prone to failure. This paper briefly introduces the basic situation of the new hydrogen compressor unit of the 1.60Mt/a diesel hydrotreating unit. Aiming at the current secondary load abnormal fault, motor bearing burnout, HydroCOM system failure and other problems occurred during the operation of the unit and combining with previous maintenance experience, the paper found out the causes of the failure and proposed some measures for improvement, which achieved good results. This provides valuable experience for long-cycle operation of reciprocating compressors of the same type.
