The pressure sensor 7 is used for detecting the pressure in the diaphragm chamber when the high-pressure diaphragm pump 6 works in the feeding and discharging periods, and transmitting the detected value to the controller 13 in real time.
The pump inlet valve 4 and the pump outlet valve 8 are both one-way valves, and in normal operation the pump inlet valve 4 only allows fluid flowing into the diaphragm pump 6 to pass through, and the pump outlet valve 8 only allows fluid flowing out of the diaphragm pump 6 to pass through.
