一、必须改革旧的检修制度 1.计划预期检修制的主要弊病是没有考虑可变因素 多年的经验证明,机械的磨损程度与机械累计工作时间成正比。随着现场地质条件、作业状态、使用应力和环境应力的不同,同等磨损程度的累计工作时间相差很大,处于数百小时到数千小时的范围内。而且,各种零件的磨损程度也有差异,加之油质、配件、材料力学性能、加工质量、安装调试水平以及操作熟练程度、工作责任
First, the old repair system must be reformed 1. The main drawback of the planned anticipatory maintenance system is that it does not consider the variable factors. Many years of experience have proved that the degree of mechanical wear is directly proportional to the cumulative working time of the machine. With the different on-site geological conditions, operating conditions, use of stress and environmental stress, the cumulative working time of the equivalent degree of wear varies greatly and is in the range of hundreds of hours to thousands of hours. In addition, there are differences in the degree of wear of various parts, plus the oil quality, accessories, mechanical properties of materials, processing quality, installation and commissioning levels and operational proficiency, work responsibilities
