随着机械的发展,维修保障工作越来越显得重要,维修消耗越来越大,以至成为难以承受的负担,甚至反过来影响着机械的发展。与此同时,人们也在追求机械管理的现代化和维修的科学化。观念在更新:对于机械使用,从过去追求单一的性能转变到评价综合效能的观念上来;对于保证机械使用的手段,由被动的、单一的维修发展到主动的、综合的保障,强调建立维修保障体系。要求建立和完善与机械设计特性相适应的维修保障系统。1 维修保障实践中存在的主要问题 机械的技术状态以完好率表示,维修保障的各项工作围绕完好率进行。由于机械完好标准的掌握、完好率的计算有很大的随意性,致使许多工作流于形式而不见成效。
With the development of machinery, maintenance work has become more and more important, maintenance costs have become even greater and greater, making it an unbearable burden and even affecting the development of machinery. At the same time, people are also pursuing the modernization of mechanical management and the maintenance of scientific. The concept of updating: for the use of machinery, the pursuit of a single performance from the past to evaluate the concept of comprehensive performance; for the means to ensure the use of machinery, from passive, a single repair to the development of proactive, comprehensive protection, emphasizing the establishment of maintenance support system. Requires the establishment and improvement of mechanical design features compatible with the maintenance support system. A maintenance of the main problems in practice The status of machinery in good condition that the maintenance of all the work around the intact rate of work. Due to the mastery of mechanical integrity standards, there is a great deal of randomness in the calculation of intact rates, resulting in many forms of work that have failed to yield results.
