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 polarity strong polar molecular sieves, and oxygen and nitrogen are non-polar molecules, when oxygen and nitrogen through the 5A molecular sieve polarity, appearance under the effect of polar molecules practical medical gas equipment, oxygen and nitrogen produced induced dipole, nitrogen and oxygen induced dipole and dipole interaction 5A zeolite polarity produces a force induction, induced polarization force easily produce far greater than the nitrogen oxide induced force generated, thus 5A molecular sieve adsorption capacity for nitrogen than for oxygen adsorption capacity, so that nitrogen is preferentially adsorbed 5A zeolite molecular sieve zeolite enriched in solid phase, the oxygen concentration in the non-solid phase, which is oxygen The product gas. 5A molecular sieve also has increased medical gas pressurized nitrogen adsorption capacity, reducing pressure adsorption capacity characteristics. Therefore, medical gas piping design, can be used when the 5A zeolite for nitrogen adsorption pressure, decompression, nitrogen desorption from 5A molecular sieve out ways to achieve PSA oxygen. Filter (filter) is a device on the transmission medium pipeline indispensable, usually installed in the inlet end equipment valves, pressure relief valves, water valve, party workers filters other devices. Filter filter cartridge has a certain size, its impurities are blocked, when you need to clean medical gas systems expert, as long as the removable cartridge, you can reload after treatment, so maintenance is extremely convenient. Filter by tube, stainless steel mesh filter (26) sewage section, transmission and electrical control components. The filter work, into the water to be filtered from the time the outlet, flows through the filter, the user must enter through the outlet pipe for process circulation, water particles are trapped in the filter inside acrobatics. This constant cycle of trapped particles down more and more, faster and slower filtration, while imports remained steady flow of sewage into the filtration hole will become smaller and smaller, so the intake, resulting in pressure between the outlet poor, when conservative difference reaches the set value, the differential pressure transmitter will transmit electrical signals to the controller, the control system startup drive motor shaft driven by the drive assembly, while open sewage outfall discharge from the outfall, when the filter After cleaning, the pressure drops below the minimum, the system returns to its original shape filtration system running.
