Transport And Storage - HYDAC International SB 330 Notice D'utilisation

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.
This stipulates 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
– Electro-magnetic operated pressure release
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
"Safety and shut-off block SAF/DSV"
No. 3.551
NOTICE
Before mounting permanently attached
adapters on the gas side of a bladder
accumulator, the gas valve insert (3) must be
removed – see fold-out page.

Transport and storage

Transport
The transport of gas-filled hydraulic accumulators
must be carried out with the utmost care and
in compliance with all relevant transport safety
regulations (e.g. on public roads, dangerous
goods regulations, etc).
Only appropriate load carrying equipment must be
used for transport and handling:
Hemp rope or transport strapping (2 I), transport
caps (2 II) or magnets for rounded objects (2 III).
NOTICE
Do not use chains.
Do not use steel cables.
Appropriate load carrying equipment is listed in
the following catalogue section:
"Bladder Accumulators standard design"
No. 3.201
DANGER
Any damaged bladder accumulator must not
be put into operation.
Storage
The hydraulic accumulator can be stored in any
position (orientation). To prevent dirt from entering
the hydraulic accumulator, it must be ensured that
the hydraulic connections are sealed off.
Bladder accumulators must be kept in a cool, dry
place, protected from direct sunlight. They can be
stored for up to three months.
If the storage period exceeds 3 months, the pre-
charge pressure (p ) must be reduced to 2 bar
0
to prevent the bladder from becoming deformed.
During commissioning, the hydraulic fluid must
flow into the hydraulic accumulator slowly to
prevent the bladder from being destroyed.
If a bladder accumulator is to be stored for more
than one year, it must be disassembled and the
hydraulic accumulator and bladder must be stored
separately.
When storing elastomers, DIN 7716 "Rubber
Products, Guidelines for Storage, Maintenance
and Cleaning" must be complied with.
