我公司圆形煤均化堆场使用的YDG80/450圆料场混匀堆取料机,采用PLC进行控制,PLC型号为CPM2AE-60CDR-A,扩展模块为CPM1A-20EDR/1。堆料机PLC与取料机型号一样。取料机和堆料机互相独立,控制和运行由中控室“组起”操作。1故障现象2006年夏天,取料机“组起”正常,但是运行一段时间后,液压料耙(简称料耙)行进到左工作极限接近
The YDG80 / 450 material stock mixing reactor used by our round coal homogenization yard is controlled by PLC. The PLC model is CPM2AE-60CDR-A and the expansion module is CPM1A-20EDR / 1. Stackers PLC and reclaimer models the same. Reciprocator and stacker independent of each other, control and operation by the control room “group ” operation. 1 Symptom In the summer of 2006, the reclaimer “group ” normal, but after running for a period of time, the hydraulic material rake (referred to as material rake) travel to the left working limit close
