Medical Oxygen Generator

PSA medical oxygen machine has the advantages of easy oxygen supply operation, fast oxygen production, and high purity, which reduces the burden of medical work and facilitates medical staff and patients.

Oxygen Capacity: 1-200Nm³/hr
Oxygen Purity: 90-95%
Oxygen Pressure: 0.1-0.5Mpa (150-200Bar Refilling Pressure can be offered)

Product Description

Oxygen is used in many areas. For example, artificially produced oxygen is used in fish farming, drinking water treatment, metallurgy, biogas plants, and in the food industry. Oxygen must be available in a specific purity, mainly when used in the medical field, e.g. in the operating theatres of hospitals and veterinary clinics. In this regard, purity indicates the proportion of oxygen in the total gas mixture.
Medical oxygen generator from a China factory can produce medical oxygen, which has an oxygen purity of 93%-95%, meets the requirements of the European Pharmacopoeia for medical gases as well as ISO standards 7396-1:2016 for pipeline systems for medical gases and 13485:2016 for the quality management system for medical device manufacturers.

China PSA medical oxygen generator manufacturer uses clean compressed air as raw material and zeolite molecular sieve (ZMS) as adsorbent, to produce oxygen gas with Pressure Swing Adsorption (PSA) technology at normal temperature. ZMS is a round granular adsorbent full of micropores inside and outside, which has the characteristic of selective adsorption. N2 has a higher diffusion rate while O2 has a lower, therefore N2 is adsorbed into ZMS while O2 is out of it. By controlling the on/off state of the pneumatic valves by PLC, adsorbing under pressure and regenerating without pressure, to separate nitrogen and oxygen gas, and create a continuous flow of oxygen with require purity.

In recent years, many hospitals have adopted their own oxygen supply mode, especially after the outbreak of the new crown epidemic, medical oxygen generators are more effective in meeting the oxygen supply in medical rescue.

In order to ensure the purity of oxygen production and oxygen production efficiency of the medical oxygen machine, in the process of using a large number of medical oxygen machine to ensure its oxygen production work smoothly, it is necessary to study and analyze its use and maintenance process, grasp the main points of the problems that may arise in the use, timely solution and good maintenance work later.

The variable pressure adsorption (PSA) method is based on the different adsorption properties of molecular sieves for oxygen and nitrogen and uses zeolite molecular sieves as adsorbents to separate oxygen and nitrogen in the air, thus selectively adsorbing oxygen in the air.

The composition of PSA oxygen generation equipment includes an air compressor, main circuit filter, air balance tank, oxygen generation host, sterilization filter, oxygen tube installer, etc. On top of that, the oxygen generator also needs to be equipped with two sets of ten bottle sets of sinks as an emergency backup oxygen source in the process.

A molecular sieve is composed of many tiny granular components, molecular sieve mass fraction, surface area are not low, generally speaking, the surface area of each gram of molecular sieve can reach 800 ~ 1000 / g. After compressed air through the air purification system to remove oil and water, solid dust, and other impurities into the adsorption tower equipped with a zeolite molecular sieve, where the nitrogen, carbon dioxide, and water vapor by the molecular sieve a large number of nitrogen, carbon dioxide, and water vapor are adsorbed by the molecular sieve, and the oxygen is separated by the adsorbent due to the large diffusion rate, and the oxygen is obtained directly from the compressed air.

To ensure a continuous and stable supply of oxygen, two or more adsorption towers are generally set up, one for adsorption and the other for regeneration of the adsorbent to enable repeated recycling. Switching of use is done at appropriate times to ensure continuous oxygen production at concentrations between 90 and 94%.

The normal air content of oxygen is 21%, the nitrogen content is 78%, and the function of the oxygen machine is to produce oxygen in the air, and the rest of the gas will be separated and discharged into the air. Generally speaking, the probability of failure of the current medical oxygen machine is very low, the normal situation of the electronic board performance is relatively stable, and there will be no failure situation. But there are exceptions ~

Failure phenomenon: the adsorption and resolution function of the molecular sieve is affected, the oxygen generator does not operate well, and the quality of oxygen produced is not ideal.

Cause of failure: As the spool and diaphragm of the inlet valve, balance valve, and nitrogen discharge valve are moving parts, it is easy to cause the rupture of the diaphragm and the deformation of the top of the spool during the long working time, which leads to the loss of the normal closing function of the solenoid valve, and then the adsorption and analysis function of the molecular sieve is affected to a certain extent so that the whole oxygen machine does not operate well. So in general, most of the failures of the medical oxygen machine are due to this problem, if this problem is eliminated, then the oxygen machine should be checked comprehensively to find out the cause of the failure. A molecular sieve is an important component of the medical oxygen machine that is missing and occupies an important position in the process of oxygen production. Affected by the environment, use conditions of moisture, oil, and so on may make the molecular sieve lose its role.

Maintenance treatment: replace the ruptured diaphragm and deformed spool in time to restore its closing function, prevent its impact on the adsorption and analysis function of molecular sieve, focus on protecting molecular sieve, regular maintenance and replacement of molecular sieve are very necessary.
