太原重工轧锻设备厂的EHF3400/2500×14000单臂铣刨床是原西德科宝公司1960年制造的产品,主要用于加工大型工件的平面、斜面和轧钢设备的油缸内孔。目前,它仍承担着繁重的加工任务。该刨床主拖动采用电机扩大机-直流发电机-直流电动机(A—G—M)调速系统,能耗非常大,电气控制采用继电器逻辑控制,线路复杂,故障率高,维修困难。改造的目的是提高设备的可靠性、稳定性,完善功能,降低电能消耗。
Taiyuan Heavy Industry rolling equipment factory EHF3400 / 2500 × 14000 single-arm milling machine is a product manufactured by the former West Cobalt Company in 1960. It is mainly used for machining the plane bore, bevel face and cylinder bore of rolling equipment for large workpieces. At present, it still undertakes heavy processing tasks. The planer main drive using motor amplifier - DC-DC motor (A-G-M) speed control system, energy consumption is very large, electrical control relay logic control, complex lines, high failure rate, maintenance difficulties. The purpose of the transformation is to improve equipment reliability, stability, improve functions, reduce power consumption.
