Change according to the requirements of pressure and flow in the compressed air system, through the air compressor fleet control strategy to control different displacement and control method of air compressor start/stop, loading/unloading, volume change and speed adjusting, etc., to ensure that the hollow press processing efficient operation mode, guarantee the stability of the system of gas pressure under the condition of the whole system run efficiently.

Through real-time acquisition system pipe network pressure and flow signal, accurate control system of the pipe network pressure, compared with the artificial control of air compressor operation, the pressure control precision is higher, demand for system changes more timely respond time, higher reliability, lower energy consumption of the system.
