3、的身心健康，改善现场的作业环境，可通过布袋式脉冲除尘器回收水泥粉尘。某水泥厂的球磨车间建有5个除尘室，每个除尘室安装了1台脉冲除尘器，每台脉冲除尘器有两个脉冲电磁阀（A阀和B阀）和1个提升电磁阀。在提升电磁阀工作期间，脉冲电磁阀才能工作。第二章 设计题目内容1.控制任务和要求（1）各个除尘器的电磁阀的控制时序。为使收尘系统阻力变化范围小，一般采用均匀间隔清灰的工作方式，即采用定时控制方式，各个除尘器的电磁阀的控制时序如图1所示：前室提升电磁阀脉冲电磁阀后室提升电磁阀脉冲电磁阀 图1t0：脉冲电磁阀的启动延时，一般取2st1：提升电磁阀的工作时间，一般取8st2：脉冲电磁阀的喷吹时间，一般取0.
4、13st3：室间隔时间，一般取17s（2）各个除尘阀的工作顺序。考虑到灰斗里绞刀负荷的均衡性、喷吹的有效性及减少清灰时的排放量，一般采用错开清灰的方式。 1A3A5A2A4A1B3B5B2B4B1A（3）系统的工作方式。为检修和维护方便，每个电磁阀应有自动/手动两种工作方式，正常工作时采用自动方式：检修和维护时，采用手动方式。（4）在各个电磁阀工作期间，应有指示灯指 示。 2.设计方案提示 （1）在自动方式下，各个电磁阀处于顺序循环控制过程中。（2）某个电磁阀工作在手动方式下，则不会影响其他电磁阀的正常工作。 （3）为节省输出点，可将电磁阀线圈与指示灯并联.（4）其操作面板如图2：图2第三章
5、设计过程和有关说明设计过程：首先，根据输入和输出端口设计I/O口，再用I/O口根据任务的设计要求编写脉冲除尘器的状态转移图，然后根据状态转移图编写梯形图，梯形图编好后运行仿真，根据功能调试梯形图再仿真，直到除尘器能完成手动与自动的转换，在自动情况下可顺利运行。 说明：在调试过程中，偶尔出现运行时功能紊乱，经过多次调试，排除程序问题。第四章 绘制电气原理图1.主电路图：2.plc硬件电路:3.I/O接口表：I口O口1室x2y02室x3y13室x4y24室x5y35室x6y4I口O口脉冲和灯O口喷吹和灯1AX7Y5Y172AX10Y6Y203AX11Y7Y214AX12Y8Y225AX13Y9Y2

7、课设，给我很大的经验与教训。最重要的就是，要根据任务要求，判断最适合的编写指令方法，如果刚开始就能判断出除尘器用状态转移图编写梯形图更直观更方便，就不会浪费这么多的时间。在自动和手动的编写时，自动与手动的转换时这次的难点，也是我最头疼的地方。原本想的是在自动的过程中加入开关设计，但怎么想都想不出，只好在最开始时用并行把手动的15段程序并在一起。先开始调试时明明分段的手动梯形图基本一致，但就是有的手动成功有的手动失败，在关闭监控后再打开，又恢复了功能。之后根据同学调试的技巧将并行程序中的SET与STL分开，果然手动的效果不再出现意外。总之，这次课设教会了我很多当初理论课没有学会的知识，实在是受益
8、匪浅。最后，O(_)O谢谢韩立强老师的耐心指导和同组同学的合作与帮助。燕山大学课程设计评审意见表指导教师评语：成绩： 指导教师： 年 月 日答辩小组评语：成绩： 评阅人： 年 月 日课程设计总成绩：答辩小组成员签字：年 月 日 燕 山 大 学 课 程 设 计 说 明 书 共 页 第 页（英文版 ） easily blame, to prevent the broken window effect.
