After decades of high-speed development, China's industry has been the first in the world, and more and more gas sources are used in its scope. Today, oxygen, one of the several gases described in the small edition, has many ways to source oxygen, but it can only be divided into high-pressure oxygen source (13Mpa pressure of cylinder high-pressure oxygen) and low-pressure oxygen source (the pressure of various oxygen generators is generally between 0.2-0.6mpa). Here's how to raise the oxygen pressure to the pressure of composite application.
Oxygen pressurization is basically a pneumatic oxygen booster pump, which is safe because no spark driven by gas can be safe and explosion-proof. The role of oxygen in industry can be roughly divided into ordinary level and food level, such as oxygen cutting, oxygen combustion supporting and so on. Food level includes pharmaceutical oxygen maintenance, oxygen purging and so on.
This gives us a simple introduction to the difference between the two kinds of oxygen booster pumps. After the ordinary oxygen is pressurized, the pressure is too high, which will lead to explosion in case of oil. When it leaves the factory, it will be degreased and oil-free through the brilliant process. The food grade oxygen booster pump is made of 304 food grade stainless steel because of the rules of the Health Bureau.
It is useful to avoid oxidation and secondary pollution. For low-pressure oxygen source, ZTT two-stage booster pump can be selected to pressurize the original low-pressure 0.2-0.8mpa oxygen to 80MPa, but it is not recommended to exceed 30MPa. There are two options for high-pressure oxygen cylinder: DTA series or DTD series.
The main difference between the two models is that the flow after pressurization is huge and small. If one DTD series is not satisfactory, multiple sets can be connected in parallel. It is suggested that customers should select pneumatic oxygen booster pump when they are over 30MPa or in confined space. As the oxygen is over 30MPa, it is very unstable. It is easy to explode in case of oil separation and electric spark.
