矿井提升机闸瓦摩擦系数测试系统

Frictional coefficient test system of the brake-tile in the pit lift

在模拟提升的工况下 ,用电测法来测量闸瓦的动摩擦系数 ,自动连续地记录摩擦过程摩擦系数的变化情况 ,同时也可以由测得值计算出在一定比压、温度和滑速下闸瓦的实际摩擦系数。

The electrical testing was used to measure the actual frictional coefficient of the brake-tile on the dition of imitating the promotion.So the changing circumstances of the frictional coefficient in the frictional course can be took notes voluntarily and continuously.At the same time,we can count the factual frictional coefficient of the brake-tile under specified pressure and sliding speed from the measured value.
