摘　　要：介绍了水冷型高温屏蔽泵结构、介质流向、常见故障类型和对应保护方式。通过对某聚酯项目中三台同规格屏蔽泵的运行数据进行对比分析,探讨了设备在故障不断加剧过程中轴承磨损、定子腔压力和定子绕组温度等关键监测指标的变化趋势和相关性。在运行数据分析结果的基础上,进一步分析了合理设置监测报警阈值的重要性,并提出了针对性的现场巡检和DCS监控报警设置建议。The structure,medium flow direction,common fault types,and corresponding protection techniques of water-cooled high-temperature shielded pumps were introduced in this article.It investigated the trend and correlation of key monitoring indicators,such as bearing wear,stator cavity pressure,and stator winding temperature during the process of equipment abnormality intensification.The operating data of three shielded pumps of the same specification in a particular polyester project were compared and analyzed.The significance of establishing appropriate monitoring alarm thresholds was further examined in light of the operational data analysis findings,and specific recommendations for on-site inspections and DCS monitoring alarm settings were made.
