题目：关于柴油机常见故障的分析与处理工艺及其关键技术的研究

摘  要

在经济不断发展的推动下，我国机械行业在发展过程中面临着新的机会和挑战。柴油机是目前大量使用的多种动力机械中热效率特高，且特别节能的动力设备，也是机械行业中一个非常重要的机械设备，在各个行业里都被广泛应用，在一些机械和船舶修造企业中的占据着非常重要的作用。柴油机在使用的过程中，由于各种因素的干扰，柴油机在正常使用的时候会出现相关故障，这些故障会严重的影响柴油机的正常运转以及安全性、可靠性，不利于柴油机的发展。用什么好的方法来解决柴油机在运行中出现的常见故障，是柴油机在更新换代过程中必须处理的一个重要问题，对推进柴油机的更新换代也起相当着重要的作用。

summary

driven by the growing economy, chinas machinery industry is facing new opportunities and challenges in the development process. diesel is widely used in a variety of power machinery ultra-high thermal efficiency, and particularly energy-efficient power equipment, machinery industry is also a very important mechanical equipment, have been widely used in various industries, in the number of mechanical and shipbuilding companies occupies a very important role. diesel engines used in the process, due to the interference of various factors, diesel when used normally appears related failures that will seriously affect the normal operation of the diesel engine as well as security, reliability, is not conducive to the development of the diesel engine. what better way to solve common faults occurring in diesel operation, the diesel engine is an important issue that must be addressed during the replacement of the propulsion engine replacement also plays quite an important role.

前  言

近几年以来，随着全球经济的飞速发展，船舶等各大机械设备在市场份额中，有着相当大的比重，因此，国内外的机械设备故障诊断技术发展也相当迅速，并推动着国民生产总值的提高。

柴油机是机械领域重要的一部分。因为它对工作环境有特殊且复杂的要求，所以，对柴油机故障诊断的研究特别重要。柴油机这种设备能持续、高效地工作，经常要好几个小时不间断甚至更长时间的连续运转，并且工作环境很恶劣，因此，在正常使用的柴油机也会经常出现各种各样的故障，而其发生故障的原因也非常复杂。

柴油机故障诊断技术的研究可以有效的帮助我们预知可能发生的故障，防止船舶机械设备损坏和货物损坏事故的发生，同时也会带来潜在的巨大的经济、社会效益。

foreword

in recent years, along with the rapid development of the global economy, ships and other major machinery and equipment in the market share, has a very large proportion, therefore, machinery fault diagnosis technology development at home and abroad is quite rapid, and promote national production raise the total.

diesel is an important part of the machinery. work environment because of its special and complex requirements, so the research on diesel engine fault diagnosis is particularly important. diesel this equipment can be sustained, efficient work, often better than a few hours a day or even longer continuous operation, and the work environment is very harsh, so in normal use diesel engines will often appear a variety of failures, the reasons for its failure are very complex.

diesel fault diagnosis technology can effectively help us to predict possible failures, prevent damage and accidents cargo ship damaged machinery and equipment, but also potentially huge economic and social benefits.
