Treatment of Electromagnetic Valve Fault of Nitrogen Generator

Treatment of Electromagnetic Valve Fault of Nitrogen Generator

Nitrogen electromagnetic valve failure

Fault judgment:

If the indicator lights of the electromagnetic valve and valve switch respond to the operation, but no corresponding nitrogen is generated, the problem may be the fault of the electromagnetic valve or the electromagnetic valve connection circuit.

Treatment method:

First check the circuit of nitrogen generator to eliminate mechanical failure. As a trouble free circuit and replace the electromagnetic valve.

Leakage fault of control valve hydraulic cylinder

Fault judgment:

Under the observation conditions of opening and closing, manually open and close the valve to see whether there is gas discharged from the exhaust of the electromagnetic valve. If the gas is discharged, the cylinder leakage control valve cannot operate the switch.

Treatment method:

Replace the backup cylinder

Nitrogen electromagnetic valve stuck fault

if the corresponding response of electromagnetic valve indicator and switch status is nitrogen, but the control valve does not act, the possible electromagnetic valve is stuck or the control valve is faulty. Check the manual switch of two exhaust valve ports or exhaust. If discharge alternately, the electromagnetic valve is complete and fails in the control of the program. Since the electromagnetic valve cannot discharge AC gas, the electromagnetic valve is stuck. 

Treatment method:

Remove the electromagnetic valve and clean the inside of the electromagnetic valve.
