矿井深度指示器应用现状

Present Application of Mine Depth Indicator

介绍了现阶段煤矿中广泛使用的立式深度指示器、圆盘式深度指示器、多绳摩擦式深度指示器、光电编码盘式深度指示器的工作原理、结构,对各种深度指示器的优缺点进行了比较,对煤矿深度指示器的选型及技术改造有一定的指导意义。

The principle,components of the depth indicator are introduced.They are vertical depth indicator,disk depth indicator,multi-rope friction depth indicator,and photoelectric encoder depth indicator.And the performance comparison of these kinds depth indicator,which could help the coal choose of the depth indicator.
