本讲通过实例,介绍煤矿机电设备可靠性数据整理的表格法与图示法。一、可靠性数据的分类表除了提炼可靠性指标外,采集煤矿机电设备可靠性数据,还有一个重要目的:从中找出影响设备可靠性的主要因素,拟定提高设备可靠性的主要措施。从第四、五讲我们已经知道,直接数据以运行状态方式给出,间接数据又分散在许多统计报表或原始汜录中。为了达到上述目的,就要将反映我们所
This talk through an example, introduction of mechanical and electrical equipment reliability data collation tables and graphical method. First, the classification of reliability data In addition to refining the reliability index, the collection of coal mine mechanical and electrical equipment reliability data, there is an important purpose: to identify the main factors that affect the reliability of the equipment to develop the main measures to improve equipment reliability. From the fourth and fifth we already know that direct data is given in operational mode and that indirect data is scattered among many statistical reports or original records. In order to achieve the above objectives, it will reflect our position
