基于霍尔元件的润滑点无油检测系统

A Lubricant Meauring System Based on Hall Element

通过分析使用于钢坯剪断机的真空滴油式注油器的工作原理，分析了引起润滑点无油的主要原因在于注油器的损坏和油路管道的堵塞，并根据这两种情况，利用霍尔效应的原理，设计并制造了可检测摩擦运动副处是否有油的滑润点无油检测系统。该系统还具有声光报警功能、控制功能和一些其它的辅助功能。采用该系统可避免机床零件的损坏，保证机床安全可靠地运行。

By discussing the principle of drop oil vacuum injector used in machine tools, two reasons why there is not oil in lubrication place are found. According to these two reasons, a measuring system based on Hall element is designed and fabricated. The system has the following functions:measuring, warning and controlling. The machine tool works in safety condition by using the measuring system.
