摘　　要：宁夏石化公司炼油催化装置热水循环泵1202-P-101在使用过程中,出现机封频繁泄漏的问题,造成现场频繁检修,影响装置长周期稳定运行。设备专业组通过分析得出影响机封频繁泄漏的原因主要为循环水质较脏、循环水管线易堵塞、机封冷却器冷却效果不佳。针对以上原因,本单位进行隐患治理,现场更换并扩粗循环水进机封冷却器管线,同时针对其中一台机泵采取整体更换为换热面积更大的机封冷却器,以此增加机封冲洗水换热冷却效率,保障冲洗效果,延长动设备长周期运行寿命。During the use of the hot water circulating pump 1202-P-101 of the refining catalytic unit of Ningxia Petrochemical Company,the hidden danger of machine seal leakage frequently occurs,resulting in frequent on-site maintenance and affecting the long-term stable operation of the device.Through analysis,the equipment professional group concluded that the main reasons affecting the frequent leakage of the machine seal were dirty circulating water quality,easy blockage of the circulating water line and poor cooling effect of the machine seal cooler.In view of the above reasons,the unit carries out hidden danger control,replaces and thickens the circulating water inlet seal cooler pipeline on site,at the same time,replaces one of the pumps as a whole with a machine seal cooler with a larger heat exchange area,so as to increase the heat exchange and cooling efficiency of the machine seal flushing water,ensure the flushing effect,and extend the long-term operating life of the moving equipment.
