What is the reason for insufficient air supply of air compressor

Insufficient air supply to the air compressor may be caused by a variety of reasons. The following are some possible reasons:

maintenance is not timely: when the operating environment of the unit is not ideal, check whether the air filter and oil filter are blocked. If the air filter and oil filter are clogged and the exhaust volume drops, you only need to replace the three filters and one oil.

The operating pressure of the unit is set too low: adjust the pressure as needed, and some companies reduce the pressure in order to save energy, so that the workshop pressure cannot rise.

Frequent unloading causes the air pressure to fail to rise: the air compressor is loaded after starting. If the pressure cannot continue to appear false loading, it is a machine loading failure. Check the loading and unloading solenoid valve or small piston, check whether there is any power supply problem or blockage, and handle the loading and unloading failure in time.

The intake valve cannot be opened or cannot be fully opened: The failure of the intake valve will cause the unit's exhaust volume to drop, so the intake valve needs to be checked regularly.

Motor failure: due to local failure of the motor coil, such as bearing wear. The motor shaft wear causes the motor speed to be lower than the rated speed and the compressor displacement to decrease.

Loose motor belt: resulting in a decrease in transmission efficiency.

There is a leak in the pipe network: a leak in the pipe network will cause the pressure to drop, and the leak point needs to be checked and repaired.

Excessive deposits in the oil-water separator, pipeline or compressed air filter cause blockage: it needs to be cleaned and replaced regularly.

The exhaust valve of the air compressor is not tightly sealed, the spring is too soft and broken, the cylinder head bolts of the air compressor are loose, the sand holes and the cylinder head gasket are damaged and the air leaks: the damaged parts need to be checked and replaced.

Air compressor cylinder liner and piston ring wear serious, resulting in air leakage: need to replace the wear parts.

Selection problem: Many users do not know the specific gas consumption of their own production at the beginning, so they select the type approximately. At this time, the exhaust pressure cannot rise and is lower than the rated exhaust pressure, which cannot meet the normal gas consumption of the factory. At this time, new units can be added to make the displacement of the air compressor more than 10-20% of the gas consumption the most scientific.

It should be noted that the above are only some possible reasons, and the actual situation may vary due to factors such as equipment model and use environment. When troubleshooting problems, it is recommended to proceed step by step from simple to complex. If the problem cannot be solved, it is recommended to contact professional maintenance personnel for inspection and maintenance.
