从摩擦学系统的概念出发 ,分析了影响刮板输送机中部槽摩擦学系统能量平衡的各种因素 ,特别对中部槽磨损失效过程中的能量转化进行了分析和探讨 分析表明 :中部槽的摩擦能量转化成 4部分 :表层和亚表层变形能量、内能的变化、形成的热量和表面能的增加 ;根据中部槽磨损类型和井下工况条件的不同 ,摩擦物体总的摩擦能量WR 的分配系数 (α)也各不相同 图 2 ,参 5
Based on the concept of tribology system, various factors that affect the energy balance of the tribological system in the middle section of the scraper conveyor are analyzed. In particular, the energy transformation during the failure of the middle tank is analyzed and discussed. The analysis shows that the friction The energy is transformed into four parts: the deformation energy of the surface layer and subsurface, the variation of internal energy, the formation of heat and the increase of surface energy. According to the type of middle slot wear and downhole conditions, the distribution coefficient of the total frictional energy WR (α) is also different Figure 2, reference 5
