PSA nitrogen generator has the characteristics of low energy consumption, high efficiency and convenience, which has played an important role in many fields. In the chemical industry, metallurgy, food, machinery and other industries are widely praised.

1. According to the technical requirements of air compressor, air dryer and filter, to ensure air quality. The air compressor and cold dryer must be overhauled at least once a year. The damaged parts should be replaced and maintained according to the equipment maintenance and maintenance regulations. If the pressure difference between the front and rear of the filter is found to be greater than or equal to 0.05-0.1mpa, the filter element must be replaced in time.

2. Check the whole nitrogen making device carefully before starting up to make sure that no tools, parts or other objects are left in the air compressor. PSA should not be welded near the oil system, and any pressure vessel should not be modified by welding or other methods.

3. The maintenance work of nitrogen plant must be carried out under the condition of shutdown and power failure.
