多年以来,日本设备维修协会设立的“装置工业PM委员会”对流程工业(主要是化学工业)装置的设备管理的基本思想从各种角度作了深入的研究.考虑到很早就在飞机方面推行的RCM(Reliability CentredMaintenance)的基本思想对流程工业的设备管理有一定的参考价值,同时为使人们进一步了解其内容,本文将介绍其概念,并探讨一些适用于一般设备管理的若干问题.1、RCM分析的展开RCM一般译为重视可靠性的维修方式,或以可靠性为中心的维修方式,是在以经验为基础的维修方式的前提下,通过对(1)故障机理的研究;(2)故障影响度的评价;(3)维修效果的评价以及各种元件(组合件)的可靠性特性的评价,找出最佳的维修作业方式.过去,维修作业多靠经验进行,对故障发生方式与维修作业的关系研究不够.50年代后期,随着装置的复杂化,不仅对性能提出了更高的要求,而且对维修的经济性引起关注,因此,提出了如何重新评价计划维修体制的问题.
For many years, the “Plant Industry PM Committee” established by the Japan Equipment Maintenance Association has carried out in-depth research on the basic concepts of equipment management for process industries (mainly chemical industry) installations. Considering that it was implemented very early on in aircraft. The basic idea of the RCM (Reliability Centred Maintenance) has certain reference value for the equipment management of the process industry. At the same time, in order to let people further understand its content, this article will introduce its concept and discuss some issues applicable to general equipment management. The development of RCM analysis RCM is generally translated into a maintenance method that emphasizes reliability, or a reliability-centered maintenance method. It is based on the experience-based maintenance method and is based on the study of (1) the failure mechanism; (2) ) Evaluation of the degree of influence of failures; (3) Evaluation of maintenance effects and evaluation of the reliability characteristics of various components (assemblies) to find out the best maintenance operations. In the past, maintenance operations mostly depended on experience and occurred The relationship between methods and maintenance operations is insufficient. In the late 1950s, with the complication of equipment, not only higher requirements were put forward for performance, but also the economics of maintenance. Since concern, therefore, it raised the question of how to re-evaluate the planned maintenance system.
