What is the reason why the air compressor can't breathe

the screw air compressor is not loaded with air, which is one of the common faults of the equipment. In case of this kind of failure, it is necessary to investigate the causes step by step. Generally, the reasons for the screw air compressor not being loaded are nothing more than the following:

1. Intake valve is not open:

after the air compressor is turned on, the internal pressure will be slowly established. When the pressure reaches 5Bar, the solenoid valve controls the cylinder to open the intake valve, and the compressor sucks air into the loading state. There may be three reasons why the air compressor does not enter the air. The solenoid valve (circuit, valve body, pipeline), cylinder (valve plate or diaphragm, seal, pipeline) and intake valve (valve plate or diaphragm, seal, pipeline) are malfunctioning.

2. Failure of pressure check valve:

screw air compressor pressure check valve is easy to judge whether there is a failure, when the pressure inside the machine is too high, but there is no pressure output, you can judge the pressure check valve failure. If the pressure check valve fails, it needs to be replaced with a new one.

3. False loading of air compressor: The main reason for the false loading of air compressor is the failure of the output point of PLC. PLC is in a running loading state. Due to the failure of the output point, no signal is given to the solenoid valve, resulting in the air intake machine not operating. PLC maintenance to professional air compressor maintenance engineers, non-professionals are not recommended to disassemble.

4. Air compressor host failure:

the failure of the main engine of the air compressor is relatively complicated. The wear of the yin and yang rotors or the lubricating oil of the air compressor will cause the failure of the main engine. If the main engine fails to load, you can find professional air compressor maintenance personnel.
