The Design And Implementation Of The Vacuum Furnace Electric Control System

Vacuum furnace for oil field production of key equipment and energy consumption equipment.Its main characteristic is to load regulation ability is strong,compact structure,cover an area of an area small,etc.Currently used vacuum furnace than before,compared to the traditional heating furnace technology safety,energy saving,and high degree of automation,are widely used in national each big oilfield.Its normal operation,is to ensure that the basis of the production of safe and efficient operation.With the rapid development of industrial automation technology,how to adopt advanced automatic control technology,the economy of automation control equipment and improve the effect of control and control level,improve energy utilization ratio and thermal efficiency,realize the energy saving high efficient,is the meaning of the research.This study mainly for Daqing Oil Field by using vacuum furnace.In order to make the vacuum furnace is more safe and efficient operation and visualization,can track the running status of equipment operation,the study is mainly according to the heating furnaceusing the environment,equipment structure,process characteristics,design a set of electric control system.For the power distribution and measuring devices,etc in the design of the hardware configuration,at the same time,using the Siemens STEP7-MICRO/WIN SMART software programming environment,on the energy saving mode control instrument parameter conversion program,pump cycle control,filling water control procedures,burner control,alarm,control and thermal control program written in detail.Visualization in order to make the furnace control,make the operator control and easy to operate,also in order to track the equipment running status,using man-machine interaction Win CC configuration software,the use of the advantages of the software,and design a vacuum phase change heating furnace of man-machine interface operation,monitor screen,alarm information,alarm query,etc.According to the production of vacuum furnace at the scene of the actual operation conditions and the data were analyzed,and the running results show that the vacuum furnace control system can meet the requirements of automatic control,and safe and reliable,stable running,flexible control,high efficiency and energy saving advantages.
