本文根据生产实践,主要介绍了应用在热处理渗碳炉等多台设备上的一台电子报警装置。设备的自控系统失效时能发出铃声、闪光及相应指令。其特点是采用了双重报警系统,即自动巡测报警与控制加热时间,当超过正常值时的报警,这两个系统相互独立工作,又相互逻辑组合,能较可靠地进行报警、判断故障性质及所在炉区。整机结构简单、易自制且成本低。 According to the production practice, this paper mainly introduces an electronic alarm device which is applied to many equipments such as heat treatment carburizing furnace. Equipment, automatic control system failure can ring, flash and the corresponding instructions. Its features are the use of a dual alarm system that automatically patrols the alarm and control the heating time, when the alarm exceeds the normal value, the two systems work independently of each other, but also a logical combination of each other, can be more reliable alarm to determine the nature of the fault And the furnace area. The whole structure is simple, easy to make and low cost.
