机械设备在运行的过程中受到各种因素的影响,常常会产生形式多样,错综复杂的故障,很容易产生生产中的不安全或者无法进行正常生产的现象。机床电气设备在工作的过程中常常产生各种无法预料的故障,这些故障按形成原因可以分为自然故障和人为故障两类。现分析了机床电气控制电路的故障防范措施,提出合理有效的故障分析和故障排除方法。 Mechanical equipment in the operation of the process by a variety of factors, often produce a variety of forms, complex faults, it is easy to produce unsafe or unable to produce normal production phenomenon. Machine tools often produce unpredictable faults in the course of their work. These faults can be divided into two types: natural faults and human faults. Now analyzed the machine electrical control circuit fault prevention measures, put forward a reasonable and effective fault analysis and troubleshooting methods.
