【摘要】:空气预热器传热元件生产线是电站锅炉生产的关键设备,主要实现钢板的轧制、剪切、收集工艺。由于国内传热元件生产线的制造尚处于起步阶段,因此研制具有自主知识产权、运行可靠、性价比高的传热元件生产线具有重要意义。本文以实际工程项目为背景,在充分了解工艺控制要求和对传热元件生产线关键工序进行研究分析的基础上,确定了生产线采用PLC控制系统,并采用现场总线PROFIBUS-DP进行通讯。主要内容有:(1)生产线控制系统硬件及网络设计。通过对伺服驱动同步、变频器矢量控制和现场总线等控制技术的研究分析,完成了控制系统的主要电气元器件选型、硬件组态及网络配置,并设计了控制系统总体方案。(2)生产线控制系统软件设计。基于STEP 7、S7-PLCSIM、Wincc flexible等软件平台,完成了生产线触摸屏程序和PLC控制程序的设计和开发。(3)生产线电气控制线路设计。采用Auto CAD绘图软件,完成了生产线控制柜和PLC线路设计。经过设备调试与验收,目前通过投产运行情况表明:本文所设计的传热元件生产线控制系统不仅满足了工艺控制要求,提高了产品质量,还大大降低了工人的劳动强度,使企业以最低的成本投入获得了最优的经济效益。
[Abstract]:The heat transfer element production line of air preheater is the key equipment of boiler production in power station. It mainly realizes the rolling, shearing and collecting process of steel plate. Because the manufacture of heat transfer element production line in China is still in its infancy, it is of great significance to develop a heat transfer component production line with independent intellectual property rights, reliable operation and high performance-to-price ratio. In this paper, based on the actual engineering project, on the basis of fully understanding the process control requirements and researching and analyzing the key processes of the heat transfer element production line, the PLC control system is adopted in the production line and the field bus PROFIBUS-DP is used for communication. The main content is: 1) production line control system hardware and network design. Through the research and analysis of servo drive synchronization, frequency converter vector control and field bus control technology, the main electrical components selection, hardware configuration and network configuration of the control system are completed. The software design of control system of production line is designed. Based on STEP 7 S7-PLCSIMI Wincc flexible and other software platforms, the design and development of touch screen program and PLC control program of production line are completed. The design of production line control cabinet and PLC circuit is completed by using Auto CAD drawing software. After the commissioning and acceptance of the equipment, it is shown that the control system of the heat transfer element production line designed in this paper not only meets the requirements of process control, improves the product quality, but also greatly reduces the labor intensity of the workers. So that the enterprise with the lowest cost input to obtain the best economic benefits.
