What are the precautions for the operation of the nitrogen generator?
1. Adjust the pressure regulating valve in front of the flowmeter and the nitrogen production valve behind the flowmeter according to the gas pressure and gas consumption. After the adjustment is completed and the purity reaches the standard, do not arbitrarily increase the flow or adjust the pressure to ensure the normal operation of the equipment.
2. Other valves adjusted by the debugging personnel should not be rotated at will, so as not to affect the purity.
3. Do not move the electrical components in the electric control cabinet at will, and do not disassemble and install pneumatic pipeline valves at will.
4. The operator should check the four pressure gauges on the nitrogen generator regularly, and make a daily record of the pressure changes for equipment failure analysis.
5. Regularly observe the outlet pressure, flow meter indication and nitrogen purity, and timely feedback and solve any problems found.
6. Carry out regular maintenance and maintenance in accordance with the technical requirements of air compressors, refrigerated dryers and filters to ensure the quality of compressed air. Air compressors and refrigerated dryers must be overhauled at least once a year, and wearing parts must be replaced and maintained in accordance with equipment maintenance and maintenance regulations; if the pressure difference before and after the filter is found to be greater than or equal to 0.05~0.1Mpa, the filter element must be replaced in time.
7. Complete the daily record form.
