14 Troubleshooting
14.1 How to proceed for troubleshooting
▶
Always work systematically and purposefully, even when under time pressure.
Random, thoughtless disassembly and changing of settings might result in the
inability to determine the original error cause.
▶
First, get a general idea of how the diaphragm type accumulator works in
conjunction with the overall system.
▶
Try to establish whether the diaphragm type accumulator worked properly in
conjunction with the overall system before the problem first occurred.
▶
Try to determine any changes in the overall system in which the diaphragm type
accumulator is integrated:
– Were there any changes to the diaphragm type accumulator's operating
conditions or operating range?
– Has any maintenance work been performed recently? Is there an inspection or
maintenance record?
– Have modifications (e.g. refittings) or repair works been performed at the
overall system (machine/system, electrical system, control) or at the diaphragm
type accumulator? If yes: What were they?
– Was the hydraulic fluid changed?
– Was the diaphragm type accumulator or machine used as intended?
– How did the fault become apparent?
▶
Try to get a clear idea of the cause of error. If necessary, ask the actual (machine)
operator.
▶
Document all work done.
