Working Process Of Industrial Oxygen Concentrator

The workflow of the oxygen concentrator is controlled by a programmable controller to operate five two position five way pilot solenoid valves, which in turn control the opening and closing of ten pneumatic pipeline valves. Five two position five way pilot solenoid valves control the left suction, pressure equalization, and right suction states respectively. The time flow of left suction, pressure equalization, and right suction has been stored in the programmable controller. In the power-off state, the pilot air of the five two position five way pilot solenoid valves is connected to the closing port of the pneumatic pipeline valve. When the process is in the left suction state, the solenoid valve controlling the left suction is energized, and the pilot gas is connected to the opening ports of the left suction air valve, left suction production air valve, and right exhaust valve, so that these three valves open, completing the left suction process and simultaneously desorbing from the right adsorption tower. When the process is in a pressure equalization state, the solenoid valve controlling the pressure equalization is powered on, and other valves are closed; Connect the pilot gas to the opening port of the pressure equalization valve, causing it to open and complete the pressure equalization process. When the process is in the right suction state, the solenoid valve controlling the right suction is energized, and the pilot gas is connected to the opening ports of the right suction valve, right suction production valve, and left exhaust valve, causing these three valves to open and complete the right suction process, while the left adsorption tower desorbs. In each process, except for the valve that should be opened, all other valves should be in the closed state.
