Abstract:

The article analysis the 4L-20/8 air compressor operation condition，made the practical air and the compressed air dynamic matching，realized the motor speed stepless adjustment，stop the motor under no-load running，and made gas production as improved conditions for intelligent control of air compressors.Intelligent control method use the computer-controlled management system，using a set of intelligent control systems to drive multiple 4L-20/8 air compressor to achieve a drag and more control，and install a pressure sensor in the tank pressure pipe，then control the regulation of air compressors.The success of the intelligent control transformation of the 4L-20/8 air compressor system is very important and has a broad application prospect，which provides a new means for enterprises to save energy and improve economic efficiency for the type of energy to run the air compressor.

Key words: air compressor, intelligent control, pressure sensor, intelligent motor control
