【摘要】：船用柴油机作为一种重要的动力机械,广泛应用于各个行业,在航运和日常生活中起着举足轻重的作用。由于柴油机具有结构复杂,工作条件恶劣等特点,导致机械故障的发生频率较高,造成相应的经济损失或人员伤亡事故。为提高船用柴油机动力装置的安全性和可靠性,对柴油机冒黑烟现象实现快捷而准确的诊断及处理,避免不必要的经济损失,对柴油机的故障诊断技术研究具有十分重要的意义。本文简述了船舶柴油机的工作原理,对冒黑烟的故障产生的原因进行了系统的分析。采取了层次分析法分析柴油机冒黑烟的主要原因,通过振动分析法结合实际案例,从柴油机的进排气系统、燃烧室容积和燃油系统三个方面进行分析、诊断、排除。实践证明,层次分析法和振动分析法能快速、准确地分析出故障原因,较好地解决了船舶柴油机冒黑烟的故障问题。随着现代技术的不断发展,船舶柴油机的监测诊断技术和可靠性也得到了进一步的发展,为船舶柴油机冒黑烟的故障诊断提供了更完善的知识库和更先进的监测和诊断方法,相信未来船舶柴油机冒黑烟故障的诊断和处理技术会更加智能化和科技化,实现视情维修,从而为社会创造出更大的经济效益。
[Abstract]:As an important power machinery, marine diesel engine is widely used in various industries and plays an important role in shipping and daily life. Because the diesel engine has the characteristics of complex structure and bad working conditions, the frequency of mechanical failure is higher, resulting in the corresponding economic loss or casualty accident. In order to improve the safety and reliability of marine diesel engine power plant, the black smoke phenomenon of diesel engine can be quickly and accurately diagnosed and treated, and unnecessary economic loss can be avoided. It is of great significance to study the fault diagnosis technology of diesel engine. In this paper, the working principle of marine diesel engine is briefly introduced. The main causes of black smoke emission of diesel engine are analyzed by AHP. Through vibration analysis combined with practical cases, this paper analyzes, diagnoses and excludes the intake and exhaust system of diesel engine, the volume of combustion chamber and the fuel system. The practice shows that the analytic hierarchy process (AHP) and the vibration analysis method can quickly and accurately analyze the cause of the failure and solve the problem of the black smoke emission of the marine diesel engine. With the continuous development of modern technology, the monitoring and diagnosis technology and reliability of marine diesel engine have been further developed, which provides a more perfect knowledge base and more advanced monitoring and diagnosis method for the fault diagnosis of black smoke emission of marine diesel engine. It is believed that the diagnosis and treatment of smoky faults of marine diesel engines in the future will be more intelligent and scientific and can realize the maintenance according to the situation, thus creating greater economic benefits for the society.
