High exhaust pressure of screw air compressors is one of the most common issues in air compressor maintenance. Many users do not know the cause and often ask what to do with high exhaust pressure of screw air compressors? Here, the Wuhan screw air compressor editor analyzes the solution for high exhaust pressure of screw air compressors.

Reasons for high exhaust pressure of screw air compressor:
① The intake valve is stuck and cannot be closed, resulting in continuous loading;
② The gas consumption suddenly decreased;
③ Loading solenoid valve malfunction, blocked but not completely blocked;
④ Unloading solenoid valve malfunction, unloading failure, pressure continues to rise until unloading is reached;
⑤ The pressure setting is too high;
⑥ Pressure sensor malfunction.

Solution for high exhaust pressure of screw air compressor:
① Disassemble the intake valve, and if it doesn’t get stuck severely, polish the rusted area with sandpaper and lubricate it with some oil. If it is severe, directly replace the maintenance package or assembly.
② Check the changes in gas consumption, and if the gas consumption is appropriately reduced, lower the high unloading pressure value;
③ ④ Check and eliminate electromagnetic valve faults;
⑤ Adjust the pressure switch settings;
⑥ Replace the pressure sensor.
