Troubleshooting


PROBLEM
Response of accumulator is slow









Long pump-up time








Accumulator fails to absorb shock pressures








Will not hold pre-charge

PROBABLE CAUSE
A) Pre-charge is too low


B) Piston is binding




C) Weak spring(s)

A) Pre-charge too low or no pre-charge pressure.

B) Low pump volume



C) Weak spring(s)

A) Pre-charge is lost


B) Pre-charge is too high

C) Diaphragm or bladder ruptured



A) Ruptured diaphragm or bladder

B) Charging valve leaks

C) Piston seal, diaphragm or bladder leaks

POSSIBLE REMEDY
A) Check pre-charge pressure and re-charge as necessary.

B) Discharge gas pressure and fluid pressure.  Be certain that both are at ambient atmospheric.

C) Disassemble and replace spring(s).
A) Check pre-charge pressure and recharge as necessary.

B) Check GPM output of pump.  See pump troubleshooting section.

C) Disassemble and replace spring(s).
A) Check pre-charge pressure, recharge as necessary.

B) Same as above

C) Check operating fluid temperature, reduce if too high.  Bladder pinched when installed; replace following manufacturer's installation procedure carefully.
A) Disassemble and replace


B) Remove and replace

C) Check compatibility of fluid and rubber material.  Disassemble and replace.  Clean, flush and refill system.
