Atlas Copco 2901141100 Common Faults and Causes of Pressure Valve:
Excessive outlet pressure: This may be caused by faults in the pressure switch, faults in the load electromagnetic valve, damage to the blow-off valve, setting of the working pressure of the pressure switch too high, faults in the intake valve, faults in the pressure sensor, or errors in the pressure gauge.
2901141100 Low outlet pressure of Pressure Valve: This may be caused by excessive on-site gas consumption, faults in the intake valve, leakage of the control gas source of the intake valve, setting of the working pressure of the pressure switch too low, errors in the working pressure caused by faults in the pressure switch, too low set value of the computer pressure, or faults in the pressure transmitter.
2901141100 Troubleshooting methods for Pressure Valve:
Excessive outlet pressure: Measure the contacts of the pressure switch to see if they are normal. If not, replace with a new part; remove and maintain the load electromagnetic valve, if still abnormal, replace with a new part; remove and maintain the blow-off valve, if damaged, update it; lower the pressure of the pressure switch; remove and maintain the intake valve, if damaged, replace it; perform calibration of the pressure transmitter, if damaged, replace it; replace the pressure gauge.
2901141100 Low outlet pressure of Pressure Valve: Suggest customers check for any leaks in the pipeline. If there are none, add a compressor; remove and maintain the intake valve, or replace with a repair kit; eliminate the leaking part; increase the upper limit of pressure to the set value requested by the customer; inspect the pressure switch, if repairable, replace with a new part; adjust the set value of the computer and perform calibration of the pressure transmitter.
