意大利进口玛连尼320型沥青拌合站轻/重油燃烧控制系统,采用美国霍尼韦尔(HoneWell)公司的基于微处理器设计生产的EC7805A型集成式控制器,其性能稳定,控制安全可靠。但是其电路控制流程复杂,难于被沥青拌合站技术人员所理解。本文以玛连尼320型沥青拌合站燃烧器控制系统为例,对控制器各端子功能及燃烧控制时序进行详细分析,并介绍其常见故障排查方法,以期对玛连尼沥青拌合站技术人员有所帮助。
Italy Mariani 320 asphalt mixing plant light / heavy oil combustion control system, the use of the United States Honeywell (HoneWell) microprocessor-based design and production of EC7805A-based integrated controller, its performance is stable, safe and reliable control . However, the circuit control process is complex and difficult to understand by asphalt technical personnel. In this paper, the control system of the Marinini 320 asphalt mixing station burner is taken as an example to analyze the function of each terminal and the timing of combustion control in detail, and to introduce the common troubleshooting methods, in order to improve the performance of Marlene asphalt mixing station technology Personnel help.
