The Working Flow Of The Oxygen Making Machine

The working process of the oxygen generator is controlled by a programmable logic controller, which is controlled by five two bit five way pilot solenoid valves, and then the electromagnetic valve is used to control the opening and closing of ten pneumatic pipe valves respectively. Five two - bit five - pass solenoid valves control the left, mean, and right suction respectively. The time course of the left suction, the equalizing and the right suction has been stored in the programmable controller. Under the power off state, the pilot gas of the five two bit five way pilot solenoid valves is connected to the closing port of the moving pipeline valve. When the process is in the left suction state, the electromagnetic valve with left suction is energized, the pilot gas is connected to the left side, and the left inlet valve, the left suction valve and the right exhaust valve opening port, so that the three valves are opened, the left suction process is completed, and the right adsorption tower is desorbed. When the process is in a state of equalizer, the solenoid valve with controlled voltage is energized, the other valves are closed, and the pilot gas is connected to the opening port of the equalizing valve, so that the valve is opened and the pressure equalization process is completed. When the process is in the right suction state, the electromagnetic valve that controls the right suction is energized, the pilot gas is connected, the right intake valve, the right suction gas valve and the left exhaust valve opening port are opened, so that the three valves are opened, the right suction process is completed, and the left adsorption tower is desorbed. In each process, other valves should be closed in addition to the valve that should be opened.
