Design of Piston Air Compressor Unit Control System based Converter
Abstract—Based on the running characteristics and high energy consumption of air compressors in coal mines, an air pressure PID closed loop control system has been designed in this paper. The system is composed of PLC, converter and sensors etc and adopts the control method of converter triple-evaporator which makes air supply Mneed-basedw. The designed system has been applied in multiple coal mines and the results show its energy saving is remarkable and potential application is widely.
Keywords —— air compressor, converter, triple-evaporator, air pressure closed loop, energy saving
