补充几个概念,说明矿山机械维修学的内容,希联系实际,认真思考,提出见解和观点来。1.狭义维修学维修学的传统概念主要是指修配工艺而言,或称为“修旧立废”,着重研究各种零件的修理方法、设备、检查等内容。传统的设备维修管理基本上是保养和大修,这种观点巳不能适应现代化科技发展和矿山机械设备的实际需要了。传统观点的主要弊病是,只抓机械设备的维修,而忽视了机械设备的改造和更新;由此而造成越修越贵,维修费用不断增长,机械设备的性能和功能越修越差,机械设备的状态越来越老化;只是机械地按着固定周期和规范化内容进行机械设备的保养和修理,而完全不管机械设备的实际现状是好是坏,缺少机械设备的运行状态监测和技术诊断,造成维修不足或过剩,带有一定的盲目性;只抓机械设备的使用和维修,而不管机械设备全过程的信息反馈和积累,忽视了机械设备全过程管理。因之,现代化矿山机械维修学的内涵更加丰富充实
Add a few concepts, explain the content of mining machinery maintenance, hope to contact the actual, serious thinking, put forward opinions and opinions. 1. The narrow concept of maintenance The traditional concept of maintenance mainly refers to the repair process is concerned, or as “repair the old legislation”, focusing on various parts repair methods, equipment, inspection and so on. The traditional maintenance and repair of equipment is basically maintenance and overhaul, which has not met the practical needs of modern technological development and mining machinery and equipment. The main disadvantage of the traditional view is that only the maintenance of machinery and equipment, while ignoring the transformation and upgrading of machinery and equipment; resulting from the more expensive repairs, maintenance costs continue to grow, the more mechanical and mechanical properties of the worse, the mechanical The state of the equipment is getting aging; the maintenance and repair of the mechanical equipment is carried out only mechanically according to the fixed cycle and the standardized contents, regardless of whether the actual status quo of the mechanical equipment is good or bad, lack of operation status monitoring and technical diagnosis of the mechanical equipment, Resulting in lack of maintenance or excess, with a certain degree of blindness; only grasping the use and maintenance of machinery and equipment, regardless of the whole process of mechanical equipment feedback and accumulation of information, ignoring the whole process of mechanical equipment management. Therefore, the connotation of modern mining machinery maintenance is more abundant
