Interpreting Test Results and Operational Effects
Low Accumulator Pressure.
Cause:
Leaking piston O-Rings.
Leaking accumulator service valve.
Normal operational leakage.
Effect:
Low accumulator pressure decreases the water available for delivery to the aeration nozzles.
If the accumulator is completely discharged (0 Psi) the water forced into the accumulator will not be forced out
when the cycling valve opens. The only water available to the nozzles is the water from the pump.
High Accumulator Pressure
Cause:
Accumulator over charged with nitrogen.
Water leaking past the O-rings. (Water collecting on top of the piston, decreasing the available area for
nitrogen).
Effect:
With the higher accumulator pressure, the area in the accumulator to store the water from the pump decreases
and the capacity of the accumulator is decreased.
