Medical oxygen system works: PSA oxygen machine is used as adsorbent zeolite 5A. 5A zeolite crystals are cage-type structure, a very well-developed crystal cave. Has a very strong cation and anion in the crystal oxygen hole constituting a highly polar molecular sieve polarity expert medical gases, while oxygen and nitrogen are non-polar molecules, when oxygen and nitrogen through the 5A molecular sieve polarity, in a polar molecule Under the effect of the induced dipole produces oxygen and nitrogen, and oxygen and nitrogen polarity induced dipole dipole interaction 5A zeolite produces a force induction, induced polarization force easily produce nitrogen oxide produced far greater than induced force, therefore 5A zeolite for nitrogen adsorption capacity greater than for oxygen adsorption capacity, so nitrogen is preferentially adsorbed zeolite 5A and medical gas enriched in the solid phase of the type of molecular sieve oxygen enriched in non-solid phase medical gases, This is the product of oxygen gas. 5A molecular sieve also has a pressurized nitrogen adsorption capacity increases, when the pressure to reduce the adsorption capacity characteristics. So, when 5A zeolite can be used on pressurized nitrogen adsorption, decompression, nitrogen desorption from 5A molecular sieve out ways to achieve PSA oxygen. Medical gas systems were inspected each section should then access the system and the system as a whole should be tested. Each medical gas piping systems shall separately to prevent cross-examination and labeled wrong then check medical gas equipment, and shall meet the following requirements: 1, compressed medical gas pipeline test pressure 0.4MPa, the vacuum should be 0.2MPa. In addition to the gas pipe to be tested, the remaining line pressure should be atmospheric. 2, with each dedicated gas terminal plug each test component should have only been tested in the gas supply gas terminal components, and should confirm the marked terminal component testing is consistent with the gas pipeline medium.
