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 catalogue sections:
"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 piston
accumulator, the locking screw (210) and the
seal ring (200) must be removed, see fold-out
pages.
3. 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 may
be used for transport and handling:
Hemp rope or transport strapping, transport
caps or magnets for rounded objects.
NOTICE
Do not use chains.
Do not use steel cables.
DANGER
Any damaged piston 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.
When supplied, piston accumulators are
suitable for short-term storage.
Piston accumulators must be kept in a cool, dry
place, protected from direct sunlight.
They can be stored for up to six months.
To prevent the seals from setting and to wet
the inside of the accumulator with the oil inside
it, the piston accumulator should be rotated by
90° after three months.
If a piston accumulator is to be stored for longer
than six months, it must be made suitable for
long-term storage.
This must be agreed with HYDAC.
