JB/T6427-2001 Variable Pressure Adsorption Oxygen, Nitrogen Equipment
This standard establishes the requirements for the quality, technical requirements, testing methods and transmission rules of variable pressure adsorption oxygen and nitrogen production equipment. Strictly follow JB/T2639-2001, JB/T2637-2001, JB/T2640-2001, JB/T6431-2001, GB/T544-1992 and the relevant industry standards. This standard is applicable to adsorption oxygen and oxygen-nitrogen production equipment with total production capacity greater than 3 m3 / h.
The equipment for producing oxygen and nitrogen under variable pressure adsorption should have an oxygen production process with a residual oxygen content of not less than 99%. The system should be equipped with safety protection devices, performance meet the requirements and can be reliably operated. Oxygen and nitrogen with stable quality can be obtained through mechanical compression. In addition, efforts should be made to reduce energy consumption and make production reliable, safe and efficient.
Equipment design and manufacturing of variable pressure adsorption oxygen and nitrogen production should meet the requirements of this standard. The equipment should be designed and manufactured in accordance with the relevant fluid delivery standards, mechanical, hydraulic and electricity in the industry. The design should consider the convenience of production operation, maintenance and safety.
Oxygen and nitrogen production equipment of variable pressure adsorption should be inspected before it is put into use, and the inspection items should basically meet the requirements of this standard. The equipment should be tested after being debugged and put into trial production. Before the initial formal production, the equipment should be operated again for 3 to 4 weeks for no-load operation and debugging tests and for debugging and performance tests of pressure, speed and transportation systems.
This standard prescribes the technical requirements for variable pressure adsorption oxygen and nitrogen production equipment, test methods, inspection rules and equipment acceptance and delivery procedures. Production enterprises should refer to the standard to carry out the design and manufacture, installation and debugging of the oxyen and nitrogen equipment under variable pressure adsorption. Enterprises should also adopt safety protection devices in design, manufacturing and installation to ensure the safety of personnel and equipment during production and operation.
