The fourth is the main reducer lubrication station control stations shall TE525 lubrication pressure,temperature,liquid level control. The fifth is gear wheel hydraulic TE326 control. Conclusions control program include: First of all, main motor for frequency conversion motor,which inverter control its speed ,auxiliary motors,bustion car’s control is relatively simple,which direct contacts with the relay control its operation. Last but not least,because of gear wheel hydraulic station,the main gearbox lubrication station’s control contents and more plex process,both adopted by the PLC control method,the use of PLC bination of hardware and software to achieve gear wheel hydraulic station,the main gearbox lubrication Stop the normal operation and fault alarm control functions.Key words Cement,Kiln,PLC,Control System目 錄摘 要 ..............................................................................................................................IABSTRACT .....................................................................................................................II1 緒論 .............................................................................................................................1 水泥生產(chǎn)工藝...........................................................................................................1 水泥熟料的煅燒 ................................................................................................2 回轉(zhuǎn)窯的發(fā)展 ...................................................................................................2 回轉(zhuǎn)窯的性能和特征 .........................................................................................3 水泥回轉(zhuǎn)窯硬件系統(tǒng)技術(shù)參數(shù) ..................................................................................32 總體方案設(shè)計(jì) .............................................................................................................4 設(shè)計(jì)任務(wù)要求...........................................................................................................4 電氣控制方案...........................................................................................................63 水泥窯控 制方式 .........................................................................................................9 操作方式..................................................................................................................9 DCS 介紹 ...........................................................................................................9 操作方式設(shè)計(jì) ...................................................................................................9 與外界的連鎖信號 ..................................................................................................10 配電系統(tǒng) ................................................................................................................114 硬件電路設(shè)計(jì) ............................................................................................................13 輔助電機(jī)的控制 .....................................................................................................13 燃燒小車的控制 .....................................................................................................13 PLC 硬件配置 ..........................................................................................................13 PLC 基本知識 ..................................................................................................13 PLC 機(jī)型選擇 ..................................................................................................15 模塊連線圖 ............................................................................................................17 PLC 輸入輸出端子設(shè)計(jì) ............................................................................................18 功能梯形圖設(shè)計(jì) .....................................................................................................20 閃爍信號的產(chǎn)生 ..............................................................................................20 主減速機(jī)潤滑站起動(dòng)及抗干擾措施 ..................................................................21 主減速機(jī)潤滑站冷卻水的投入和關(guān)閉...............................................................21 潤滑站綜合起停 ..............................................................................................22 主減速機(jī)潤滑站油泵電機(jī)的工作......................................................................22 主減速機(jī)潤滑站加熱器的運(yùn)行 .................................
