Do you know what to do when the pressure of the air compressor is insufficient? Let me explain it to you now!

1. This situation may be caused by the failure of the barometer. At this time, you need to observe the air pressure gauge. If the indicated pressure is insufficient, you can let the engine run at medium speed for a few minutes. If the pressure still does not rise or rises slowly, if you step on the brake pedal and the deflation sound is very strong, then It means that the barometer is damaged, and the barometer should be repaired at this time.

2. The transmission belt between the air compressor and the engine is too loose or slipping, or the pipeline between the air compressor and the air tank is broken or the joint is leaking. At this time, check whether the belt of the air compressor is too loose, from the air compressor to the air storage tank, to the control valve intake pipe, and whether the joints are loose, broken or leaking.

3. The oil-water separator, pipeline or air filter is blocked due to excessive sediment. At this time, you should check whether the oil-water separator and the air filter and the dirt in the pipeline are blocked because of too much dirt. If it is blocked, the dirt should be removed.

4. The exhaust valve of the air compressor is not tightly sealed, the spring is too soft or broken, the cylinder head bolt of the air compressor is loose, the sand hole and the cylinder head gasket are damaged and cause air leakage. At this time, check whether the exhaust valve of the air compressor is leaking, whether the spring is too soft or broken, etc. Replace or repair the damaged parts according to the fault found.

5. The cylinder liner, piston and piston ring of the air compressor are worn out and even leaks. At this time, check whether the cylinder liner and piston ring of the air compressor are excessively worn.
