Energy-saving type multi-air-compressor air supply system

The invention relates to the field of air compressor energy saving control, in particular to an energy-saving type multi-air-compressor air supply system. A plurality of air compressors, a plurality of air storage bottles and a valve box are included. The air compressors communicate with the air storage bottles through the valve box. The valve box comprises a machine case, a controller, a first air conveying pipeline, a second air conveying pipeline, a converging air row, a first electromagnetic valve, a first flow dividing air row, a second electromagnetic valve, a second flow dividing air row, a first air storage pipeline, a second air storage pipeline and an air gathering pipe. The controller is arranged in the machine case, the mechanisms are arranged in the machine case, and the converging air row and the first flow dividing air row are in communication through the first electromagnetic valve, the flow dividing air rows are in communication through the second electromagnetic valve, and the converging air
