PAGE 大连海事大学 毕 业 论 文 二 ? ? 七 年 五 月 “海慧”轮燃油分油机工作原理及故障分析 专业班级：轮机管理02-12 姓 名：王 飞 宇 指导教师：＿＿＿＿＿＿＿ 轮机工程学院 内容摘要 摘要：离心式分油机具有净化时间短，流量大和效果好的优点，是船舶净化燃油必不可少的关键设备。它的可靠性是保证燃油系统安全运行的主要环节，但往往由于对燃油分油机日常保养不到位或维修操作不当等原因，在船舶燃油系统工作中，分油机出现各种故障，油中水分和杂质加剧了燃烧室部件和喷油设备元件的腐蚀和磨损，引起主机工作不良，进而影响船舶的正常航行 本文介绍了海慧轮离心式燃油分油机FOPX609分离筒与排渣系统结构，分析内外配水系统，阐释排渣过程工作原理。针对该分油机工作过程中产生不排渣故障，根据分油机其结构特点和排渣过程工作原理，由简单到复杂地分析了该故障的起因，且进行了相应检查，查出该故障原因以及提出如何解决该问题。 从故障的发生到彻底解决过程中，我们表现出团结互助的宝贵精神，但也要看到管理人员的技术水平和工作经验有限。因此提高管理者的业务水平和促进经验交流也显得重要。 关键词：分油机 配水系统 排渣机构 滑动圈 滑动底盘 工作水 密封水 ABSTRACT：The centrifugal oil separator has advantages of short time consumed for purification ,great throughout, and good effect .It is necessary and important device for ship .Its reliance is important link to ensure the safety running of fuel oil system .But because of bad usual maintenance or improper repair operation etc. ,there are many troubles in the separator when the fuel oil system is under operation .The impurities and water from fuel oil increase the risk of erosion and wear of combustion parts and injecting device ,which will cause main engine bad work and then affect the normal sail. Basic on the analysis of separator bowl and discharge system structure ,water- distributed system and related discharge function of the centrifugal oil separator (FOPX609),some detailed causes have been verified and relevant measures have been taken to correct such a default as well . In final from this repair operation ,there is full of unity around us but our personnel skill is limited and management for spare parts is in a mess .So it will be undoubtedly valuable for us to lay emphasis on further management on our devices, our personnel skill level and experience.
