Repairing and Calibration Auxiliary Condenser Dump Valve

Condition of Auxiliary Condenser Dump Valve

Condition of Auxiliary Condenser Dump Valve

Signal from the condenser gravitational pressure tank to the automatic level control is not right, necessary to test tap of the tank condenser

Pressure gauge out automatic level control signal from the input signal on the pressure gauge valve positioner is not worth the same, needs to be calibrated pressure gauge out automatic level control signal and the valve positioner input signal

Signal range of automatic level control has not ruled or open the right scale on the pressure out of the positioner to the valve diaphragm, need calibration accuracy trigger input signal with the output pressure of the positioner valve to the diaphragm valve.

Pressure gauge on the incoming supply valve positioner is not working, need replacement pressure gauge.

There are leaks air pressure in the automatic level control unit, need further improvement

 Repairing and Calibration Auxiliary Condenser Dump Valve

Data equipment as follows:

1. Automatic Level Control Filter Regulator (need to be calibrated because the effect on supply pressure effect on the sensitivity of the signal settings and setting levels)
