Transport And Storage - HYDAC International SB Série Mode D'emploi

2. Equipment and Safety
Devices
The equipment, installation and operation of
hydraulic accumulators are subject to different
regulations in different countries.
In the Federal Republic of Germany, for
example, they are regulated by the "Industrial
Safety Regulation" (BetrSichV) or EN 14359.
These require the following minimum
equipment:
– Shut-off device,
– Device which protects against excessive
pressure(must be type-tested, either using
a prototype or through individual expert
assessment),
– Pressure release device between the
hydraulic accumulator and the shut-off
device,
– Pressure measurement device marked with
the maximum permitted operating pressure,
– Connection point for a test pressure gauge.
The following can also be fitted:
– Safety device for excess temperature,
– Solenoid-operated unloading valve.
For further safety information and relevant
equipment (accessories), please refer to the
following brochures:
"HYDAC Accumulator Technology"
No. 3.000,
"Safety Equipment for Hydraulic Accumulators"
No. 3.552,
"Charging and Testing Unit FPU"
No. 3.501 and
"Safety and Shut-off Block SAF/DSV"
No. 3.551.
NOTE
Before mounting permanently attached
adapters on the gas side of a bladder
accumulator, the gas valve insert (3) must be
removed.

Transport and storage

Transport
The transport of gas-charged accumulators
must be carried out with the utmost care
and in compliance with all relevant transport
safety regulations (e.g. in the public domain,
dangerous goods regulations, etc.).
Only appropriate load carrying equipment
must be used for transport and handling, e.g.
magnets for rounded objects (2 III), or hemp
rope or transport strapping (2 I).
NOTE
Do not use chains.
Do not use steel ropes.
DANGER
Any bladder accumulator which has been
damaged during transport must not be put
into operation.
Storage
If the storage period before commissioning is
no longer than 3 months, then it is sufficient to
store the pre-charged accumulator in a cool,
dry place, protected from direct sunlight.
The accumulator can be stored in any position.
To prevent dirt from entering the accumulator, it
must be ensured that the hydraulic connections
are sealed off.
If the storage period exceeds 3 months, the
pre-charge pressure must be reduced to
2 bar to prevent the bladder from becoming
deformed. During commissioning, the hydraulic
fluid must flow into the accumulator slowly to
prevent the bladder from being destroyed.
If a bladder accumulator is to be stored for
more than one year, is must be disassembled
and the accumulator and bladder must be
stored separately.
When storing elastomers, DIN 7716 "Rubber
Products, Guidelines for Storage, Maintenance
and Cleaning" must be complied with.
