SHL燃煤锅炉动力部分PLC控制系统设计VIP专享VIP免费

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、计算机控制系统发展到目前所采用的触摸屏+PLC显示控制系统。对于日常生活中供热供水的燃煤锅炉房，普遍采用PLC（可编程控制器）来控制锅炉运行所需的各种动力设备。本文采用先进的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实用的控制方案，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。本设计还采用三菱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ABSTRACTWiththeimprovementinthelevelofindustrialautomationandtheleveloftheboilerprocessimprovement,industrialautomationandthecontroloftheboilersimplyfromDDZ-Ⅲsysteminstrumentation,computercontrolsystemdevelopedtotouch-screen+PLCControlSystemcurrently.Asdailywatersupplyforcoal-firedheatingboilerroom,PLC(programmablelogiccontroller)iscommonlyusedtocontrolavarietyofpowerequipmentrequiredinboilerrunning.Inthispaper,advancedPLCcontroltechnologyisusedincontrolofthesuctionfan,afanandsecondfan,thepumpmotor,pumpmotoruptothecoalmachineofcoal-firedboilerintheboilerroom,thedesignofelectricpowerequipmentsuchasasetofreasonablecontrolandpracticalproposalsthatcanachievetheorderofstartandstopallkindsofelectricalpowerequipment,aswellasfaultalarmandprotectionfunctions,thereductionintheboilerroomofthesecurityrisksandeconomiclossesattheleast;Atthesametime,thisarticleisalsoaboutaboilerroomforlightingdistributionprojectplanninganddesigning.ThesimulationdesigningofpowercontrolpartisrealizedbythesimulationsoftwareofMitsubishiPLC.itcouldimprovethereliabilityandintegrityofcontrolprocedure.KEYWORDS:powercontrolofboilers,PLC,powerdistributionandlighting目录摘要.........................................................................................................................................................1ABSTRACT...................................................................................................................................................2目录.........................................................................................................................................................3第一章锅炉控制的概念和发展前景....................................................................................................61.1锅炉控制的基本概念.................................................................................................................61.2锅炉控制技术的现状与发展.....................................................................................................61.3本设计采用的控制方案.............................................................................................................81.3.1PLC的基本概念.............................................................................................................81.3.2PLC控制的优势.............................................................................................................9第二章锅炉动力设计的内容和原始资料说明..................................................................................102.1SHL型锅炉的结构分析................................................................................
