Maintenance and repair
Make sure that the maximum pressure for the accumulator is not exceeded.
f
Ensure that the gas valve is securely closed after each inspection or adjustment.
f
Before dismantling hydraulic accumulators, the liquid pressure in the accumulator
must be reduced to ambient pressure (i.e. be in a depressurized condition).
Service, maintenance and/or replacement of hydraulic accumulator components
may only be carried out by sufficiently trained personnel (see Chapter 2.9
"Obligations of the operator") on the basis of written instructions and by using
parts and materials, the manufacture of which has been certified as being in
accordance with current specifications.
Before dismantling an accumulator, it must be completely depressurized on
both the hydraulic fluid and the gas side.
Hose lines
10.2.7
Hose assemblies consist of an elastic part (hose) and fittings mounted on
both sides.
Hose lines are components requiring permanent monitoring.
DANGER
! Risk of breaking hose lines due to overload or aging (UPE5)!
Danger to life, risk of injury!
Replace the hose lines after 6 years at the latest or if damage is visible.
f
Replace the hose lines if one of the following is determined during the inspection:
f
Damage of the outer layer down to the core
–
(e.g. abrasion points, cuts or cracks).
Visible traces of overheating, fire: Carbonization, blistering or fouling due to
–
partial heat impact (hot spots).
Embrittlement of the outer layer (formation of cracks in the elastic part).
–
Deformation not corresponding to the original shape of the components in
–
both depressurized and pressurized condition.
Leaks.
–
Damage or deformation of the fitting (sealing function impaired).
–
Corrosion of the fitting reducing function and stability.
–
Hose working loose from the fitting.
–
Storage time and service life exceeded.
–
Disassembly from the system
