Oxygen Cylinder Filling System Pressure, Oxygen Loading, Selection


The oxygen cylinder filling system is a device used to compress oxygen into liquid or high-pressure gas, and then store it in the oxygen cylinder for transportation and use. The system typically includes components such as air separators, compressors, coolers, dryers, filters, metering pumps, and oxygen storage tanks. Oxygen cylinder filling systems are widely used in medical, industrial and aviation fields.


Oxygen Cylinder Filling System


What is the filling pressure of oxygen cylinder? The filling pressure of an oxygen cylinder can vary depending on the size and type of cylinder, as well as the country and regulations governing its use. However, in general, the filling pressure of a standard medical Oxygen cylinder is around 2000 psi (pounds per square inch) or 137 bar.


How is oxygen filled in cylinders? Filling oxygen into the oxygen cylinder filling system generally needs to go through the following steps:


Air Separation: Separation of nitrogen, oxygen and other components in the air, usually using an air separator.


Compression: The pure oxygen obtained after air separation is compressed so that it reaches the state of liquid or high-pressure gas.


Cooling: Cooling compressed oxygen for storage in oxygen cylinders.


Drying and Filtration: Oxygen is dried and filtered to remove impurities and moisture.


Metering filling: Use a metering pump to control the filling amount of oxygen and ensure it meets the standard requirements.


Storage: Store the filled oxygen in oxygen cylinders for transportation and use.


It should be noted that during the oxygen cylinder filling process, strict safety operating procedures must be followed to ensure the safety of operators and equipment.


How to choose an oxygen cylinder filling system? The following factors need to be considered when choosing an oxygen cylinder filling system:


Filling capacity: choose the filling capacity according to actual needs to ensure that it can meet the needs of use.


Filling pressure: Select the appropriate filling pressure according to the usage scenario and requirements, usually high pressure or low temperature liquid oxygen can be selected.


Degree of automation: Choose equipment with different degrees of automation according to the production process and operation requirements, which can reduce manual intervention and improve production efficiency.


Safety performance: Choose equipment with good safety performance, including explosion-proof, leakage alarm, automatic shutdown and other functions to ensure the safety of operators and equipment.


Quality certification: Choose equipment that has passed ISO quality certification to ensure its stable and reliable quality.


Manufacturer: Choose a manufacturer with good reputation and good service to obtain better after-sales service and technical support.
