Vacuum Oil Purifier Control System Based on PLC
The working principle of turbine oil filter was analyzed.The functions of the control system were pointed out.The hardware and PLC control program were designed.The address assignment of PLC and the programming method of the control program were introduced.The flow diagram of the system program was given.All the functions are normal and the facilities is stable since it runs.So this system has some utility value.
A configuration supervisory system based on PLC is designed and developed for automatic control and real-time supervisal of vacuum oil purifier. Based on the system, the purifier can be simulated in industrial PC, which builds up the foundation for im-proving the running level of the purifier.
According to the requirements and operational procedures,a complet control system was established with PLC as controlling core,touch screen as man-machine interface and ladder diagram as programming language to realize automatic operation.The PC configuration software WinCC uses RS485 bus communication to achieve online real-time monitor of vacuum degree and automatic control of vacuum system.This control system has simple and reliable hardware,flexible configuration and stable operating software so as to meet the vacuum measurement and control requirements of the auxiliary pumping systems.
