China OEM Liquid Oxygen Suppliers – VPSAO vacuum pressure swing adsorption oxygen production equipment – Juxian

The working principle of

◆ After entering the adsorption tower with zeolite molecular sieve, nitrogen, carbon dioxide, water vapor in the air are absorbed by molecular sieve and oxygen because of large diffusion rate through the adsorbent to achieve separation.

◆ When nitrogen and other impurities adsorbed in the adsorption tower reach a certain degree, reduce the pressure to make the zeolite molecular sieve desorption, so that the adsorbent regeneration, can be reused.

After-sales maintenance

1, each shift regularly check whether the exhaust muffler is emptied normally.

Exhaust silencer such as black carbon powder discharge indicates that carbon molecular sieve powder, should be shut down immediately.

3, clean the dust and dirt on the surface of the equipment.

4. Check the inlet pressure, temperature, dew point, flow rate and oil content of compressed air regularly Normal.

5. Check the pressure drop of the air source connecting parts of the control air path.
