Good Quality with Competitive price for oxygen generator
After air compressor compressed air after cleaning, degreasing, drying, into the air storage tank, through the air inlet valve, left intake valve into the left absorption tower, tower pressure increases, the nitrogen molecules in the compressed air is zeolite molecular sieve adsorption, adsorption of oxygen through the adsorption bed, not after left to produce valve, oxygen valve into the oxygen tank, this process is called left, The duration is tens of seconds.
After the left suction process, the left adsorption tower and the right adsorption tower are connected through the pressure sharing valve, so that the pressure of the two towers reach equilibrium, this process is called pressure sharing, lasting for 3 to 5 seconds. After the end of pressure equalization, compressed air through the air inlet valve, right inlet valve into the right adsorption tower, nitrogen molecules in compressed air by zeolite molecular sieve adsorption, enriched oxygen through the right gas valve, oxygen gas valve into the oxygen storage tank, this process is called right suction, lasting for tens of seconds. At the same time, oxygen adsorbed by zeolite molecular sieve in the left adsorption tower is released back to the atmosphere through the left exhaust valve depressurization, which is called desorption. Conversely, when the left tower absorbs, the right tower is also desorption. In order to make the molecular sieve step-down release of nitrogen completely discharged into the atmosphere, oxygen through a normally open backblowing valve is blowing the adsorption tower is desorption, the tower of nitrogen out of the adsorption tower. This process is called back blowing, and it occurs simultaneously with desorption. After the end of right suction, enter the pressure equalization process, and then switch to the left suction process, have been going on, so as to continuously produce high purity product oxygen.
Oxygen generator workflow is controlled by the programmable controller five two five-way pilot solenoid valve, and then by the solenoid valve respectively control ten pneumatic pipeline valve open, close to complete. Five two five-way pilot solenoid valve control left suction, pressure equalization, right suction state. The time process of left suction, pressure equalization and right suction has been stored in the programmable controller. In the state of power failure, the pilot gas of the five two five-way pilot solenoid valve is connected to the closing port of the pneumatic pipeline valve. When the process is in the left suction state, the control of the left suction solenoid valve is energized, the pilot gas is connected to the left suction inlet valve, the left suction production valve, the right exhaust valve opening, so that the three valves open, complete the left suction process, while the right adsorption tower desorption.
When the process is in the state of pressure equalization, the control of pressure equalization solenoid valve power, other valves closed; The pilot gas is connected to the opening of the pressure equalizing valve to make the valve open and complete the pressure equalizing process. When the process is in the right suction state, the control of the right suction solenoid valve is energized, the pilot gas is connected to the right suction inlet valve, the right suction production valve, the left exhaust valve opening, so that the three valves open, complete the right suction process, while the left adsorption tower desorption. All valves except those that should be opened shall be closed during each phase of the process.
