基于故障树的某型船主冷凝器真空偏低原因分析

Analysis of Low Vacuum Causes for Main Condenser of Specified Ship based on Failure Tree

主冷凝器是船舶蒸汽动力装置的重要组成部分,其可靠性直接影响到整个蒸汽动力装置系统的运行状况。文章在分析引起主冷凝器真空偏低的原因的基础上,利用故障树理论绘制出主冷凝器真空偏低故障树,并对其进行了定性分析。研究结果有助于装备使用人员和工厂技术人员更快更准地查找故障原因。

Main condenser is an important part of steam power plant of ship.The reliability of the main condenser affects directly the work status of the steam power plant.After analyzing the reasons for the low vacuum of main condenser,the fault tree drawing of the low vacuum of main condenser is drawn by using the theory of the fault tree.The results may help the users of the equipment and the engineers of factory to find the failure cause more quickly and accurately.
