【摘要】:随着石化装备日趋大型化、高速化、自动化、智能化,一旦设备发生故障很可能导致严重的事故,轻则影响生产效率,重则引起重大经济损失,甚至可能危机生命和财产安全,,造成极其严重的后果。为了有效地对设备维护资源进行合理的配置,研究新型的维修管理方法势在必行。以可靠性为中心的维修(RCM)方法已经在航空、武器装备领域得以成熟应用,然而国内石化装备在应用RCM技术进行装备的维修和管理方面仍然处于起步阶段,许多问题有待解决。总结出石化装备应用RCM的主要问题和解决方案,将会更好的指导RCM在石化装备领域的发展。 基于上述背景,本文首先总结了航空、武器等领域的装备应用RCM的经验(主要包括数据问题、模型问题和软件关联问题的解决经验),将这些经验拿到石化领域,解决石化装备备应用RCM出现的问题。对应石化装备应用RCM的各个主要问题,提出了相应解决办法和经验借鉴,并绘制成了表格方便查看。 其次,针对石化企业实施RCM决策难的问题(主要包括RCM实施过程中企业的组织和管理问题),重点总结了这些突出问题的来源,对照航空、武器装备领域RCM的发展经验,总结出了问题解决方案,并绘制成了表格方便查看,为更好地落实RCM做准备。 再次,在总结传统维修周期优化模型的基础上,开发了适合石化装备的蒙特卡洛依据安全性和依据经济性的维修周期优化模型,分别用实例说明了新模型的实用性和方便性,并且与传统维修周期优化模型进行了对比,为后面开发RCM分析系统做准备。 最后,根据RCM应用和落实过程中的突出问题,开发了RCM维修任务分析系统,系统所能实现的功能分别体现了前文中总结的RCM应用和落实中问题的解决方案。这一系统是用VB和Matlab语言程序开发的,核心内容为RCM逻辑分析和维修周期计算。系统内包含传统的逻辑分析模型和维修周期优化模型,针对传统模型,系统给这些模型分配了智能化界面,可以通过人工输入初始值,然后通过简单操作输出维修策略或者维修周期。在传统RCM逻辑分析模型和周期计算模型的基础上,系统还可以根据实际情况自定义逻辑分析模型和维修周期优化模型,大大增强了系统对于不同的设备零部件的适用性。
[Abstract]:As petrochemical equipment becomes more and more large-scale, high-speed, automatic and intelligent, once the equipment fails, it is likely to lead to serious accidents, which will affect the production efficiency, cause heavy economic losses, or even endanger the safety of life and property. In order to effectively allocate the equipment maintenance resources reasonably, it is imperative to study new maintenance management methods. The field of weapons and equipment has been mature and applied, however, the domestic petrochemical equipment is still in its infancy in the maintenance and management of equipment using RCM technology. There are many problems to be solved. The main problems and solutions of RCM application in petrochemical equipment are summarized, which will better guide the development of RCM in petrochemical equipment field. Based on the above background, this paper first summarizes the experience of the application of RCM in the fields of aeronautics, weapons and other fields (including data problems, model problems and software association problems), and brings these experiences to the petrochemical field. This paper solves the problem of petrochemical equipment preparation application RCM, corresponding to each main problem of petrochemical equipment application RCM, puts forward the corresponding solution and experience reference, and draws the form to be convenient to view. Secondly, aiming at the difficult decision making of implementing RCM in petrochemical enterprises (including the organization and management of enterprises in the process of RCM implementation), the sources of these outstanding problems are summarized, and the development experience of RCM in the field of aviation and weaponry is summarized. Summed up the problem solution, and drawn into a table for easy viewing, for better implementation of RCM. Thirdly, on the basis of summarizing the traditional maintenance cycle optimization model, a Monte-Carlo maintenance cycle optimization model based on safety and economy is developed for petrochemical equipment. Examples are given to illustrate the practicability and convenience of the new model. And compared with the traditional maintenance cycle optimization model, preparation for the development of RCM analysis system. Finally, according to the outstanding problems in the application and implementation of RCM, a RCM maintenance task analysis system is developed. The functions of the system reflect the solutions to the problems in the application and implementation of RCM, which are developed by VB and Matlab. The core content is RCM logic analysis and maintenance cycle calculation. The system includes traditional logic analysis model and maintenance cycle optimization model. According to the traditional model, the system assigns intelligent interface to these models, which can input the initial value manually. Based on the traditional RCM logic analysis model and cycle calculation model, the system can also customize the logic analysis model and maintenance cycle optimization model according to the actual situation. The applicability of the system to different equipment parts is greatly enhanced.
