Components of Generator

Main components and principle for equipment model selection

Air pressurization equipment and vacuumization desorption equipment: They adopt Roots blower and vacuum pumps that have demonstrated by domestic and foreign counterparts and proven by practice to be the most suitable to VPSA oxygen generators and high quality products produced by large scale professional manufacturers.

Adsorption bed(normal pressure vessels): Adopt the vertical structure adsorption bed of mature technology whose airflow distributor must ensure the even distribution of air. Adsorption bed must be fabricated by professional manufacturers with design &manufacture qualification of the first and second grade pressure vessels.

Program controlled valve: the selected valves must ensure the switching speed, sealing performance and the life of the sealing surface meets the requirement. They are purchased from joint venture enterprise and proved by practice. Key parts like actuators and electromagnetic valves are all imported.

Instrument control system and electric control system: purchased or imported from joint venture or state-owned large and medium-sized enterprises to ensure and satisfy the design requirements and long-term stable operation of equipment.
