What causes the air compressor not to pump air?

The main reasons are as follows

1. There is no voltage in the power supply

2. Contactor failure

3. The air compressor is loose, the pressure valve is stuck first, the valve piece is deformed or broken, damaged, etc.

4. There is too much dirt at the inlet and outlet.

5. The motor of the air compressor is burnt out

6. Transmission mechanism jammed

Maintenance method:

1. First, check whether the power supply and voltage are normal.

2. Check the working circuit of the contactor to eliminate the fault or replace it with a new one.

3. Check the pressure relief valve components, clean and replace the failure parts, dismantle the cylinder head, check the valve plate, and replace the deformed and broken valve plate.

4. Dismantle and inspect the cylinder head, clean the valve seat piece and valve piece, and clean them regularly.

5. Repair the motor failure of the air compressor or contact the manufacturer to replace the motor

6. Check and repair the transmission system
