We welcome inquiries from all major users. 1. Ensure normal supply and operation of the machine's required power, air source, and temperature conditions; especially stabilize the power supply voltage to reduce damage to controllers and solenoid valves caused by power issues. 2. Always monitor the air storage tank pressure, keeping it between 0.7 and 0.75 MPa, and do not let it fall below the rated value. 3. Check the automatic drain daily to prevent clogging and loss of drainage function. If clogged, slightly open the manual valve, close the automatic drain valve, then remove and disassemble the automatic drain for cleaning. Use soapy water to clean the automatic drain. 4. Operators should regularly check the three pressure gauges on the machine, record pressure changes daily for equipment failure analysis, and continuously observe the flow meter and nitrogen purity to maintain the output nitrogen purity. 5. Regularly check the cleanliness of the heat sink of the refrigerated dryer weekly to avoid reduced efficiency and lifespan due to poor heat dissipation. 6. Operate and perform daily maintenance according to the instrument usage guidelines. Periodically check the sensitivity of solenoid/pneumatic valves, the pressure range of pressure regulators, the accuracy of gas analyzers, the compaction of adsorption towers, the exhaust condition of mufflers, and the cleanliness of the inner tubes of flow meters.

Cause: 1. Check valve leaking. 2. Blowback valve opening too large. Treatment: 1. Replace check valve or internal seal ring. 2. Adjust blowback valve opening amount. Two: Fault phenomenon: Purity decline. Cause: 1. Adsorption pressure too high (>0.8Mpa). 2. Adsorption pressure too low (<0.6Mpa). 3. Adsorption pressure unstable. 4. Air source contains excessive water and oil. 5. Inlet air volume too large, causing pressure to rise too quickly. 6. Leakage at outlet interface. 7. Carbon molecular sieve poisoned, ineffective, or pulverized. Treatment: 1. Reduce inlet pressure. 2. Increase inlet pressure. 3. Add a storage tank at the inlet. 4. Install an oil-water separator before the inlet. 5. Adjust the inlet regulating valve to reduce air intake. 6. Remove and reconnect. 7. Replace carbon molecular sieve. Three: Fault phenomenon: Nitrogen generator not working. Cause: 1. Power indicator light not on. 2. Power plug or socket has no electricity. Treatment: 1. Check if the fuse is normal (the fuse location is at the lower end of the power cord and nitrogen generator socket). Use a flathead screwdriver to gently pry out the fuse. There are two fuses, one in use and one spare; replace if necessary. 2. Check if the plug or socket has electricity. Four: Fault phenomenon: Pressure rises slowly. Cause: 1. Insufficient air intake. 2. Severe interface leakage. 3. Check valve leaking or blocked. Treatment: 1. Increase air intake flow. 2. Remove and reconnect. 3. Check and clean the check valve. Five: Fault phenomenon: Pressure of one tower remains at zero. Cause: 1. Computer controller not working. 2. Valve not working, possibly due to burnt solenoid coil or stuck valve core. 3. Pressure gauge might be faulty. Treatment: 1. Check and debug. 2. Gently tap with a metal object to check if the tightening screw at one end of the solenoid valve has magnetic attraction. If the coil is proven to be faulty, the valve core might be dead. Turn off the power, open the valve group, take out the valve group, gently wipe the valve core and the dust in the valve center with a clean soft cloth, then reassemble. If the coil is burnt, replace the coil. 3. Check and replace the pressure gauge.
