1. The air compressor uses a large amount of air on the spot. It is generally recommended that customers check the pipeline for air leakage;

2. The common failure of the intake valve of the air compressor causes insufficient opening of the gate valve. First remove the intake valve for maintenance, or replace the maintenance device;

3. The air intake valve of the air compressor controls the air source leakage, resulting in insufficient opening of the gate valve or failure to open. The leaking device needs to be removed;

4. The pressure switch setting of the air compressor is too low during work. The pressure limit should be adjusted upwards;

5. The common failure of the pressure switch of the air compressor leads to an error in the pressure during work. Need to repair the pressure switch, replace the device if it cannot be repaired

6. The pressure preset value on the air compressor computer is too low or the pressure transmitter is faulty. First adjust the preset value on the computer, and make the pressure transmitter, calibrate it, and replace the new device if the transmitter is often faulty;

7. The load relay of the air compressor has a common failure, and the leakage of steam results in insufficient control of the pneumatic valve. First remove the load solenoid valve for maintenance, if it cannot be repaired, replace it with a new device;

8. The air filter of the air compressor is blocked. First remove the air filter for maintenance, if the filter device is blocked, replace it with a new one;

9. The oil and gas separator of the air compressor is blocked. First check whether the pressure difference of the oil and gas separator has reached 0.8-1 kg, and if so, replace the new device;

10. The transmission belt of the air compressor transmission system is very loose, which reduces the efficiency of the transmission system. The transmission belt of the transmission system must be adjusted, and if it is damaged, a new device must be replaced;

11. The inlet valve coupling of the air compressor is damaged, resulting in insufficient opening. The air inlet coupling must be replaced;

12. The high-efficiency reduction of the synchronous motor of the air compressor leads to insufficient opening. The synchronous motor needs to be replaced with a new device.
