所有机械设备都存在摩擦现象,摩擦会缩短设备零部件的使用寿命。随着矿山机械化程度的不断提高,因机械摩擦而产生的磨损和能源消耗以及维护维修工作也日益增大。
All machinery and equipment exist friction phenomenon, friction will shorten the life of equipment components. With the continuous improvement of mine mechanization, wear and energy consumption due to mechanical friction as well as maintenance and repair work are also increasing.
