What should I do if the exhaust pressure of the oil-free air compressor is insufficient?
Symptom: When the engine is running and the air compressor is filling the air storage tank, the barometer indicates that the air pressure cannot reach the initial pressure value.
problem causes:
- The barometer is malfunctioning.
- The transmission belt between the air compressor and the engine is too loose and slippery, or the pipeline between the air compressor and the air tank is broken or the gasket is leaking.
- The oil-water separator, pipeline or air filter is blocked by excessive sediment.
- The air compressor exhaust valve blade is not sealed, the spring is too soft or broken, the air compressor cylinder head bolts are loose, the grinding hole and cylinder head gasket are damaged and leak air.
- The cylinder liner, piston and piston ring of the air compressor are worn or even leaked.
- Observe the pressure gauge. If insufficient pressure is indicated, run the engine at moderate speed for a few minutes. The pressure is still not rising or rising slowly. A very loud blowing sound when the brake pedal is depressed indicates that the air pressure gauge is damaged. Repair the barometer.
- If there is no deflation sound in the above test, or the deflation sound is very small, please check whether the air compressor belt is too loose, from the air compressor to the air storage tank to the pipe control valve intake valve, and whether the gasket is loose, crack or leak.
- If the oil-free air compressor is not filling the air tank, please check the oil-water separator, air filter and pipeline for excessive dirt and blockage. If it is blocked, please clean up the dust.
In addition, we also need to pay attention to:
- Air leakage – this is the possible cause of this failure. You can start an oil-free air compressor and stop it when the air tank has a certain pressure (slightly above atmospheric pressure). Then use your ears to listen for air leaks in external pipes, air supply pipes, one-way valves, safety valves, pressure switches, etc. If there is an air leak, the leak needs to be repaired.
- Air demand exceeds high air supply: Your air demand exceeds the high air supply of your oil-free air compressor, and the machine is overloaded. You may think that you are not producing enough gas. We’ve been in this situation several times, so double check to see if your gas consumption is increasing recently.
- If the air source is still insufficient after the above two inspection steps, the scalp bowl of the oil-free air compressor may be worn and needs to be replaced.
