制氢装置锅炉给水泵故障分析与处理

Fault analysis and treatment of boiler feed water pump of hydrogen production unit

某制氢装置锅炉给水泵在生产运行过程中出现流量和出口压力下降的现象,通过对设备的解体检修和故障分析,找到了造成故障原因是在锅炉给水泵内部的隔板与壳体口环发生了电偶腐蚀,并提出了相应的解决方案。

Based on the phenomenon of flow and discharge pressure drop of BFW pump of hydrogen production unit existed during production operation,through disassembly and overhaul made to the equipment,and combined with the fault phenomenon in damage,this paper analyzed in details that the fault cause was galvanic corrosion in electrochemical corrosions that occurred in baffle and shell mouth ring inside of BFW pump.The short-term and long-term solutions were proposed,and finally the production problems were solved.
