文档介绍：I 单螺杆空气压缩机的结构毕业设计论文说明书摘要本设计主要阐述了单螺杆空气压缩机的工作原理与工作过程。并详细阐述了其控制系统的设计方法及控制原理,采用了目前世界上较为先进的可编程控制器——三菱 FX2N-64MS ,实现空压机无人留守的自动化控制。该 PLC 具有体积小、一体封装、工控能力强、可扩展等一系列优点完全可以满足生产的需要。设计中为了满足可靠性的要求,特别设立了声光自动报警系统,及BCD 码故障指示装置实现了双重保护,工作更加的安全可靠。在其相序、缺相保护电路中引进了功能强大的相检芯片 TC783A ,该芯片工作可靠,可承受 9—15V 的电压,耐压范围广,是目前较为理想的相序、缺相检测电路用芯片。关键词: 单螺杆空压机 PLC 自动化控制 TC783A II Abstract T he paper describes m ainly on the design of single screw pressor working principle and working process ,a nd detailed design of the control system and control theory, Use of the world's more advanced programmable logic controller--MitsubishiFX2N-64MS, No one left to achieve the automation pressor control. The PLC has a small, integrated package, industrial capacity, scalability and other advantages of full production to meet the needs of. Design in order to satisfy the requirements of reliability, in particular the establishment ofa sound and light automatic alarm systems, and installation instructions BCD code failure to achieve a double protection, the more safe and reliable. In its phase sequence, and none of the protection circuit to introduce a powerful chip with Frederick TC783A, The chip is reliable and can withstand the voltage 9-15V, voltage range is the ideal sequence, missing phase detection circuit chip.
