Abstract: The configuration and working principle of the vacuum condensate system for the cargo pump turbine of a oil tanker are described combining with the liquid level alarm faults occurred during the sea trail. The possible reasons that cause faults are analyzed and finally found out based on the simulation by AFT Fathom and troubleshooting for the real ship, enabling the elimination of the faults. It is of great significance to study and summarize the vacuum condensate system and its faults because of the complexity of the vacuum condensate system and the typicality of its faults. It can provide references for the ship design and fault elimination in the future.

Key words: vacuum condensate system, cargo oil turbine, condensate centrifugal pump, AFT Fathom, fault analysis

摘要： 针对油轮货油泵透平真空凝水系统,结合某船试航中发生的液位报警故障,对真空凝水系统组成和工作原理进行了说明,对可能故障原因进行了分析,结合AFT Fathom软件仿真和实船故障排查,最终找出原因并使故障得以排除。由于真空凝水系统的复杂性和故障的典型性,对此进行研究总结具有重要意义,并可对以后船舶设计和故障排除提供参考。
