Design of Air Compressor Speed Control System Based on the Technology of Frequency Conversion

Air compressor is widely used in the industrial and mining establishment. Firstly, this paper analyzed the existing problem on traditional controlling way of velocity modulation system on air compressor, then elaborated the controlling principle of frequency conversion. Finally, a designed practical example by frequency conversion technical is given on the air compressor. It is proved that frequency conversion can be very convenient for continuous adjustment and maintain the parameter stability of pressure, greatly improve work efficiency of the compressor, and it is a efficient measure for energy saving.
