I. APPLICATION AREAS

PSA oxygen generator is favored by users because of its remarkable advantages. It is widely used in metallurgical combustion, chemical industry, environmental protection, building materials, light industry, medical treatment, aquaculture, biotechnology, sewage treatment and other fields.

II. Technical characteristics

Perfect fluency design, optimal use effect;

Reasonable internal components, uniform distribution of airflow, reduce high-speed impact of airflow;

Special protection measures for molecular sieves to extend the service life of molecular sieves;

Simple operation, stable operation, high degree of automation, can be run by no one;

Automatic interlocking oxygen emptying device to ensure product oxygen quality;

III. Working principles

By using the principle of PSA pressure swing adsorption, the nitrogen and oxygen molecules in the air are separated by molecular sieve,

oxygen retention, nitrogen discharge. At room temperature, the power supply can be continuously separated from the air to produce high concentration oxygen under rated oxygen flow.

IV. Material of molecular sieve

A lithium low silicon oxygen molecular sieve (93%±2) has the advantages of high oxygen purity, high production ratio, small mechanical wear and long life.

V. Service life

The purity of oxygen was attenuated to 85%±3 after 6000 hours and 80%±3 after 12000 hours

After 20000 hours, the purity of oxygen attenuates to 70%+3, and the internal molecular sieve should be replaced when the oxygen concentration is not enough for use.

VI. Environmental requirements for the use of oxygen production systems

1. ambient temperature :5℃~40℃

2. relative humidity :≤80 per cent

3. atmospheric pressure :86 kPa~106 kPa

4. environment non-corrosive gas and strong magnetic field

VII. Methodology

1. place the equipment in a specific position (smooth, dry, well ventilated and heat dissipation) in the process flow, more than 40 cm from the wall; ensure that the silicone tube is connected with the oxygen outlet of the machine to facilitate the delivery of oxygen.

2. water body oxygenation machine must be higher than the water level to prevent water from returning to the oxygen machine, the oxygen unit will not be used once the water machine.

3. power supply, power indicator light, voltmeter display current voltage.Turn on the switch, run the indicator light, the air pump starts to work, the machine panel "Flowmeter" is adjusted to the required calibration position, the output port has oxygen output.Turn off the switch after use.
