Causes of Insufficient Air Pressure of Air Compressor and Brief Description of Maintenance Methods

1. Barometer failure

2. The transmission belt between the air compressor and the motor is loose and slipping or the pipeline between the air compressor and the air storage tank is broken or the joint is leaking

3. The oil-water separator, pipeline or air filter are clogged due to excessive deposits

4. The exhaust valve of the air compressor is not tightly sealed, the spring is too soft or broken, the cylinder head bolts of the air compressor are loose, the sand holes and the cylinder head gasket are damaged and leak air

The air compressor cylinder liner, piston and piston ring are worn out and even leak air

1. Observe the air pressure gauge, if it indicates that the pressure is insufficient, let the motor run at a medium speed for several minutes, and the pressure still does not rise or rise slowly. repair barometer

2. If there is no sound of deflation or the sound of deflation is very small in the above experiment, check whether the drive belt of the air compressor is loose, whether the joint is loose, cracked or leaking from the air compressor to the air tank and then to the intake pipe of the control valve

3. If the air compressor does not inflate the air storage tank, check whether the oil separator, air filter and pipeline are blocked by too much dirt. If it is blocked, the dirt should be removed

4. Further check whether the exhaust valve of the air compressor is leaking, whether the spring is too soft or broken, whether there are blisters in the cylinder head, whether the gasket is damaged, and replace or repair the damaged parts according to the fault found

1. Check whether the cylinder liner and piston ring of the air compressor are excessively worn, and check and adjust whether the installation direction of the unloading valve is consistent with the direction marked (arrow).
