SHL燃煤锅炉动力部分PLC控制系统设计VIP专享

摘 要随着工业自动化程度的提高和锅炉工艺水平的日益完善，工业锅炉自动化控制从简单地 DDZ-Ⅲ 系统仪表、计算机控制系统进展到目前所采纳的触摸屏+PLC 显示控制系统。对于日常生活中供热供水的燃煤锅炉房，普遍采纳 PLC（可编程控制器）来控制锅炉运行所需的各种动力设备。本文采纳先进的 PLC 控制技术，针对民用锅炉房中燃煤锅炉的引风机、一次风机、二次风机、给水泵电机、补水泵电机、给煤电机、炉排电机等动力设备设计出一套合理而有用的控制方案，能够实现各种电机的顺序启停以及动力设备的故障报警和保护功能，最大限度的降低锅炉房的安全隐患和经济损失；同时本文还对对锅炉房的供配电照明工程进行了详尽的规划设计。本设计还采纳三菱 PLC 仿真软件对动力部分的控制方案进行模拟，有效地提高了控制程序的可靠性和完整性。关键词：锅炉动力控制，PLC，供配电照明ABSTRACTWith the improvement in the level of industrial automation and the level of the boiler process improvement, industrial automation and the control of the boiler simply from DDZ-Ⅲ system instrumentation, computer control system developed to touch -screen + PLC Control System currently. As daily water supply for coal-fired heating boiler room, PLC (programmable logic controller) is commonly used to control a variety of power equipment required in boiler running.In this paper, advanced PLC control technology is used in control of the suction fan, a fan and second fan, the pump motor, pump motor up to the coal machine of coal-fired boiler in the boiler room, the design of electric power equipment such as a set of reasonable control and practical proposals that can achieve the order of start and stop all kinds of electrical power equipment, as well as fault alarm and protection functions, the reduction in the boiler room of the security risks and economic losses at the least; At the same time, this article is also about a boiler room for lighting distribution project planning ...
