摘要
针对硬度检测设备中的模拟直流传动子系统故障率高、运行速度不易调节、不能满足钢管生产节奏加快要求的问题,采用通用的西门子6RA70全数字直流传动装置,对硬度机传动系统进行了数字化,成功解决了全数字直流传动系统与原模拟系统的接口和系统参数的调整问题,并重点研究和解决了使用通用传动系统进行压力闭环控制问题,提高了生产节奏,并消除了设备隐患。
The direct current analog drive is subject to system failure vulnerability and difficult speed adjustment. As result, the requirements of quickened production can't be fulfill. To solve the problem, we replaced the old analog DC drive with Simens 6RA70 digital serials, and successfully solved the interface problem between the digital DC drive and the analog system and especially the technical problems of using general DC drive to control the torque. The project increased productivity and removed the hidden trouble of production.
