Product Description

High purity 99% welding cutting oxygen generator
PSA (Pressure Swing Adsorption) is an advanced gas separation technology, based on the physical adsorption of the internal surface in the adsorbent to gas molecules, separating the gas by the characteristics of absorbing to the quantity of different gas in general pressure. The CMS (Carbon Molecular Sieve) is a sorbent picked up from the air, used in separating Oxygen and Nitrogen molecular. The absorption quantity of CMS is greatly higher for Oxygen than Nitrogen under the same pressure.

Oxygen generator QA
1. What is the difference between a VPSA oxygen generator and a PSA oxygen generator?
The PSA oxygen generator is suitable for use under 300 cubic meters and has the characteristics of simple and convenient, movable.
VPSA oxygen generator is suitable for more than 300 cubic meters of use, the greater the gas volume, the lower the energy consumption.


2. What is the difference between a fish pond aerator and a fish pond oxygen generator?
The aerator is a self-contained air pump that mixes 20% of the oxygen in the air into the water.
The oxygen generator is dissolved in water by producing 90% pure oxygen.
Merchants need to consider the choice of aerobics or oxygen generators based on the type of fry, increasing the oxygen production rate to increase the production cycle, and the total ratio of fish ponds.

3. What is the purity of the PSA oxygen generator?
The purity of the general PSA oxygen generator is 90%-93%.
Our company's PSA oxygen generator can reach 95%, 98%, up to 99+%.

4. What should I pay attention to when using the oxygen generator for ozone?
Ozone supporting oxygen generators mainly need to select an oxygen generator with stable gas volume and purity to avoid ozone concentration and production due to instability.

5. How to maintain the PSA oxygen generator
The daily maintenance of the oxygen generator is relatively simple:
(1) The air compressor should be regularly maintained, air filter, oil, and oil should be replaced by the manufacturer at regular intervals according to the instructions.
(2) The dryer should regularly check the pressure of the refrigerant to make it timely. The heat sink should be cleaned with compressed air every day. The filter element should be replaced regularly. The normal temperature is 8000H. It depends on the specific situation and pressure difference.
(3) Open the air storage tank drain once a day and drain the condensate from the air.
(4) Check the automatic drainer daily to avoid clogging and lose drainage. If it is blocked, open the manual valve slightly, close the self-discharge valve and then remove the automatic drainer to disassemble and clean. When cleaning the automatic drain, use soap to clean.
(5) The oxygen generator mainly checks the working pressure of the adsorption tower, and records the purity and flow rate.

The impact toughness of weld is different with the transition coefficient of alloying elements. MAG welding, the active gas is only 20%, the alloy elements in the wire transition coefficient is high, the impact toughness of the weld is high. CO2 welding active gas is 100%, manganese and silicon alloy elements in the welding wire are deoxidized, the alloy element transition coefficient is slightly lower, the impact toughness of the weld is not as high as MAG welding.

Oxygen is a surface active element that reduces the surface tension of the liquid metal, making the droplets smaller and the transition easier. Also can reduce the

Oxygen welding

Oxygen welding

The influence of hydrogen, because of strong oxidation, in order to prevent the burning loss of elements and reduce the addition of splashing oxygen should not be too much. In 1 ~ 3%. Maximum of 4%.

We added some oxygen in the GMAW of aluminum. About 4%. There are almost no holes after radiographic inspection. But for some reason it burns through easily and turns black.

Operation Precautions

3.1 The welding site shall not store inflammable and explosive materials, and shall be equipped with fire fighting equipment, adequate lighting and good ventilation. [1]

3.2 No fireworks within 10 meters around acetylene generator (acetylene bottle) and oxygen bottle. The distance between acetylene generator and oxygen cylinder shall not be less than 7 meters.

3.3 For the welder's protective work clothes, the jacket shall not be tucked into the trousers, the hem of the trousers shall not be rolled up, and the toe shall not be tied outside the trousers.

3.4 Each acetylene hose must have a tempering device. Floating bucket acetylene generator is prohibited.

3.5 Check the equipment, accessories and pipes for air leakage. Test with soap and water. No open flame or smoking is allowed around.

3.6 Copper shall not be used in acetylene generator parts and random tools, in case copper and acetylene contact will cause copper acetylene explosion. Copper alloys containing less than 70% copper can be used.

3.7 Calcium carbide should have appropriate lumpiness. The amount of calcium carbide added at one time should not be too much, and small pieces of calcium carbide should not be used intensively, let alone the powder, in case of violent reaction and explosion caused by the increase of pressure in acetylene generator.

3.8 The use of medium pressure acetylene generator (the highest working pressure is 1.5Mpa when the pressure is used, in addition to the need to install tempering prevention device, but also to install pressure gauge and safety valve), the pressure to maintain the rated value, safety valve to reliable action, water to often keep clean, calcium carbide decomposition mortar to timely remove.

3.9 Stamping acetylene generator gas chamber, gas extrusion chamber and tempering preventer should be equipped with a corresponding area of pressure relief film, and tempering preventer should be equipped with a check valve device.

3.10 When oxygen is used indoors or outdoors, it must be properly stored to prevent tipping. When there is outdoor work, oxygen cylinders should be installed in the pergola to avoid strong sunlight.

3.11 Oxygen cylinders should generally be placed in an upright position. In rare cases, when lying down, the cylinders should be slightly higher.

3.12 Grease is strictly prohibited on oxygen cylinders and acetylene cylinders. Do not use grease gloves to carry oxygen and acetylene bottles.

3.13 Oxygen cylinder cap must be removed by hand or wrench. Hammer and other iron instruments are prohibited.

3.14 Unscrew oxygen cylinder and acetylene cylinder valve not too fast to prevent pressure airflow surge, resulting in accidents such as cylinder valve rushing out.

3.15 Oxygen cylinder nozzle shall not be contaminated with grease. Winter use, such as bottle mouth frozen, do not use fire, can only use hot water or steam heating.

3.16 Do not use all oxygen in the oxygen tank, at least 0.05mpa of oxygen should be left.

3.17 Acetylene bottles shall not be subjected to violent shocks or shocks, lest the porous fillers in the bottles sink and form cavities, affecting acetylene storage.

3.18 Acetylene bottles should be placed upright during operation to prevent the outflow of copper propyl with acetylene to avoid danger.

3.19 Acetylene bottle surface temperature should not exceed 30-400C, too high temperature will reduce the solubility of propylene copper to acetylene, resulting in a sharp increase in acetylene pressure in the bottle.

3.20 The connection between the pressure reducer and the bottle valve must be reliable. Leakage is strictly prohibited to avoid explosion accidents.

3.21 Do not use up all the acetylene in the acetylene bottle. 0.1mpa acetylene gas should be left and the cylinder valve should be closed.

3.22 Do not strike when opening oxygen or acetylene valve to prevent spark.

3.23 After the work, the oxygen valve and acetylene valve should be closed in time, and the torch is not allowed to be placed in the container or under the workbench.

3.24 When the acetylene pipe is blocked, do not blow it off with oxygen compressed air.

3.25 When tempering occurs, turn off the oxygen valve first and then the acetylene valve; When the acetylene tube is on fire, the method of bending the tube can be used to extinguish the fire.

3.26 Toxic, harmful, flammable and explosive substances must be removed in advance for pressurized containers, airtight containers, all kinds of oil drums, pipes and workpieces with combustible liquid, the pressure of containers and pipes must be removed, and the sealing state of containers (open mouth, unscrew cover) should be eliminated before work.

3.27 Air vents must be left when welding and cutting airtight hollow. When welding inside the container, the outside must be supervised and ventilated. Do not weld in containers that have been painted or sprayed with plastic.

3.28 When welding at heights, safety measures shall be taken in addition to the relevant provisions in the "Working at heights Operation Rules". The ground is guarded. Flammable and explosive items must be moved away from 10 meters.

3.29 After the work, the acetylene generator should be cleaned, the work site should be checked and cleaned, and the fire can be extinguished before leaving.
