To take laying 8×19S-13mm wire rope for elevator for example,the pre-deformation device and post-straightener of 8/450 closer are redesigned and made.
以捻制8×19S-13电梯用钢丝绳为例,对8/450合绳设备的预变形器和后调直器进行重新设计和制造,将预变形器改为卧式锥形结构,后调直器由5轮3组改为7轮4组。
6) DC speed regulating
直流调速
1.
Traditional electro-excavator control systems have some disadvantages such as dated technology,high failure,low efficiency,high run cost and so on,thus a digital control DC speed regulating device is designed and developed for electro-excavator.
本文针对传统的挖掘机电控系统存在技术落后、故障高、动态效率低、运行成本高、耗能高等缺点,设计了一套基于数字控制的挖掘机直流调速系统,系统采用小功率的CT-M75R驱动器,驱动12只大功率晶闸管组成的正反全控桥主回路,在控制回路中将电压反馈与电流反馈信号接入CT-M75R驱动器,利用驱动器内部丰富的软件功能,编程实现电压与电流的综合反馈。
