B220龙门刨床是洛阳铜加工厂一大型关键设备,从1969年开始使用至1996年已服役27年。该设备电器元件严重老化,故障频繁,且许多主要电器元件现已淘汰,无厂家生产。因此,对该设备电气系统进行技术改造已刻不容缓。 在改造电气系统的同时,为扩大加工范围和能力,我们将它改造为刨铣磨多功能机床。 原B220龙门刨床主传动采用50年代的电机扩大机、发电机、电动机组(简称K—F—D系统)双电机拖动方式,总装机容量为355kW,电耗大,噪声大,占地
B220 planer is a large-scale key equipment Luoyang Copper Processing Plant, from 1969 to 1996 has been in service 27 years. The electrical components of the equipment are seriously aged with frequent faults and many of the major electrical components are now eliminated and are not manufactured by manufacturers. Therefore, the technical transformation of the electrical system of the equipment is urgent. While remodeling the electrical system, we transformed it into a multi-function machine for planing, milling and milling in order to expand the machining area and capacity. The original B220 planer main drive using 50 years of motor expansion, generator, motor (referred to as K-F-D system) dual motor drag, the total installed capacity of 355kW, power consumption, noise,
