普通皮带机综合保护装置
一、概述summary
本装置适用于有爆炸性气体和煤尘的矿井中,用来对皮带运输机进行综合保护及集中控制。
其具有以下特点:
1、语言预警及语言事故报警功能,语言报警既能报出故障性质又能报出发生故障的皮带机号,这事同类产品所不具备的;
2、采用双音频传输技术传输系统中皮带机的运行状态,使得系统运行状态对位显比较直观,这也是同类产品所不具备的;
3、具有同类产品相同的功能,如“集控、手动控制、综合保护”及通讯等功能;
4、速度传感器寿命长、灵敏度高、磁钢和传感器间安装距离能达到50mm以上,便于安装,且显示直观;
5、功能板之间散接线很少,很大程度上减少了接线的故障,使得装置运行比较可靠。
This product, can centralized control and integrated protect the belt converor, is suitable for use in the coal mine underground where there are explosive gas and coal dust.
With features:
1. This device has a voice pre-warning and voice incident alarm, which can not only display the failure nature, but also report the failure belt drive, which is not available for other similar products.
2. It adopts double-voice transmission to transmit the conveyor’s running stage, in this way, it is more easily to know the running stage of system, which is not available for other similar products.
3. Centralized control, manual control and integrated protection.
4. Speed sensor has such advantages as long life, high sensitivity, the distance between magnet steel and sensor is above 50mm, assemble easily and display directly.
5. Cables between feature boards is so few that it lessens the faults of connection to a great extend, and makes operation more reliable.
