Using the driving air as the driving medium, the input air and low-pressure input carbon dioxide pressure signals are received through the PLC terminal to achieve the system's automatic boost start-stop function. The system is equipped with a digital display pressure gauge, which can set the air pressure range value and high-pressure output. Carbon dioxide pressure range value. When the high-pressure output carbon dioxide pressure is higher than the set upper limit setting range, the system stops boosting work, when the pressure is lower than the set lower limit setting range, the system starts boosting work. Manually set the output pressure value of high-pressure carbon dioxide to achieve different output pressures to meet different production processes and test conditions.
