烧保险,是机床电气各类故障中最普遍、最易发生的故障,而且检查时麻烦,费时间。现将机床电气烧保险的原因和检修方法介绍如下。一、熟悉机床电气控制线路原理机床电气控制线路原理图复杂但直观,是根据生产机械运动形式对电气控制系统的要求而绘制的,用以表示电动机和电器的工作 Burn insurance, is the most common electrical machine fault, the most prone to failure, but also trouble checking, time-consuming. Now the cause of electrical burn machine and maintenance methods are described below. First, the familiar machine tool principle of electrical control circuit diagram of electrical control circuit complex but intuitive, is based on the production of mechanical movement of the electrical control system to draw the requirements of the system to represent the work of the motor and electrical
