Design and Improvement of PLC-Based Air Compressor Exhaust Pressure Control System
Aiming at the problem of poor operation stability of air compressor exhaust pressure control system,a PLC-based air compressor exhaust pressure control system is proposed.The control system takes S7-200 series PLC as the core,and the hardware part and software part of the air compressor are designed.Practical application shows that:PLC-based air compressor exhaust pressure control system meets the expected requirements,can operate safely and stably,reduce the probability of accidents,and save about 554,000 yuan per year,with significant economic benefits.
