Sometimes the exhaust pressure of the air compressor is too high. In this case, the cause of the problem must be found and solved in time, because the higher the air compressor pressure, the better. The internal pressure of the air compressor exceeding the rated value will damage the valves and valves. Parts may even explode in severe cases.
- Cooling system
If the air pressure in the middle of the air compressor is too high, it is likely that there is a problem with the cooling system. If it is an air-cooled machine, you can check whether there is too much dust on the surface of the cooler, whether the fan is running smoothly, and whether the air duct is Not unobstructed. If it is a water-cooled machine, first check the inlet and outlet water temperature, flow rate and pressure difference. The most common problem with water-cooled machines is scaling of the water channels, which makes the heat exchange effect worse. In that case, the cooler needs to be cleaned. Secondly, there may be foreign matter blocking the water channels. Resulting in insufficient cooling water.
- Electrical automatic control system
If the high exhaust pressure eventually triggers an alarm, it may be that the unloading pressure is set too high and the system pressure reaches the alarm value but there is still no unloading. This can be done by simply changing the setting value, because the protection mechanism of some manufacturers is not very good in this regard. You can also check whether the intake valve is not opened or closed properly. Stop the machine and check the small air pipe and private cylinder. If there is a regulating valve, check it as well.
- Compressed air system
If the machine is loading and unloading normally and the system gas consumption is stable, if an alarm occurs, pay attention to the time when the alarm occurs and analyze it based on the actual situation, such as the system pipeline valves and the action of the one-way valve inside the machine. It is very rare for the instantaneous gas consumption to decrease sharply. Encountered, because there is still the buffer of the gas tank.
