The maintenance of the equipment in the two flowmeter oxygen generator systems mainly includes the maintenance of air compressors, refrigeration dryers, filters, and oxygen generators.

　　The two flowmeter oxygen generator equipment factories believe that the periodic maintenance of the oil screw air compressor is mainly the periodic replacement of the air inlet filter, and the annual replacement of the lubricating oil and oil separator. Oil-free piston air compressors also require regular replacement of piston rings and supplemental lubricants. In order to ensure the stable and reliable operation of the oxygen production system and the long-life operation of the compressor, the compressor must be maintained in accordance with the periodic maintenance methods and measures recommended by the two flowmeter oxygen generator manufacturers.

　　The two flowmeter oxygen generator equipment manufacturers recommend that the periodic maintenance of the air-cooled dryer is mainly to purge and clean the sewage outlet regularly; the water-cooled dryer is mainly to regularly clean the water condenser to prevent scale deposits and blockages. Please read the operation and maintenance instructions of the air dryer carefully, and maintain the air dryer in strict accordance with the periodic maintenance methods and measures recommended by the two flowmeter oxygen generator equipment manufacturers.

　　The oxygen generators of the two flowmeter oxygen generators basically do not need periodic maintenance. The user can check whether the oxygen generator is running normally when all the equipment of the company is overhauled every year. If normal, no maintenance is required.
