直流调速装置6RA70在矿井提升机上的应用

Application of DC Speed Regulating Device 6RA70 in the Mine Hoister

矿井提升机是矿山生产的关键设备,因其运行的工艺特点决定了提升机电机因负载和运行方式不同而处于频繁的转换工作状态,直流调速装置6RA70是具有电流内环和速度外环的双闭环调速系统,并具有提升机运行参数的显示和故障报警功能,很好地满足了提升机运行速度调节平滑、停车位置准确的要求,使得提升机的运行更加安全可靠。

hoisterwas key equipment in the mine production, due to its operation characteristics, the hoister＇s motor working infrequent conversion of work status during different load and operation mode. The DC speed regulating device 6RA70 had double closed-loop speed control system for the inside current loop and outside speed loop, which also has the parameters display and fault alarm function.It was meet the demand of the mine hoist＇ s smooth speed adjustment and the accurate parking, the safer and more reliable running of the hoist was realized.
