Air compressor common troubleshooting

 

1. The machine does not start: check the main switch and power cord, check the motor;

 

2. The machine does not load after starting up: adjust the setting value of the pressure switch or replace the pressure switch, check or replace the solenoid valve;

3. The compressor does not unload, and the safety valve releases: adjust the setting value of the pressure switch or replace the pressure switch, check or replace the solenoid valve;

 

4. Excessive oil consumption: use oil according to the recommendation, lower the oil level to the normal position, remove the oil return line for cleaning, and replace the oil-gas separator filter element;

 

5. The exhaust pressure is lower than the specified value: reduce the gas consumption or increase the compressor, check the system leakage, clean or replace the intake filter element, replace the oil-gas separator filter element, check or replace the solenoid valve, overhaul the intake control valve, replace belt, adjust the setting value of the pressure switch;

6. Compressor high temperature protection shutdown: improve the environmental ventilation conditions, clean or clean the cooler, add oil to the specified position, replace the oil filter;

 

7. The compressor runs unloaded, the exhaust pressure still rises slowly, and the safety valve releases: check or replace the solenoid valve, overhaul the intake control valve, overhaul the unloading pipeline;

 

8. Safety valve relief: overhaul or replace the safety valve, overhaul the minimum pressure valve, replace the filter element of the oil-gas separator, overhaul or replace the pressure switch, check the intake control valve or solenoid valve.
