Instruction and Maintenance Manual Hydro Accumulator HBS
GB
For optimal performance, place the accumulator as close as possible to the consumer.
Preferred mounting position is vertical, gas valve on top. If installed horizontally, the operating
conditions must are observed.
8.1.7 Assembly
During assembly of the hydraulic accumulator is to be observed:
- Make sure that the connected pipe system is assembled free of tension and safely.
- Make sure that the hydraulic accumulator is properly secured regarding uncontrolled
movements.
HENNLICH
- clamps and brackets are suitable for this purpose and as accessory.
- Avoid external tensions to the accumulator.
8.1.8 Final checks before commissioning
The final review before operation must be performed in the accordance with the current
authorization safety rules state laws.
e. g. Approval testing by a notified body etc.
8.2 filling with nitrogen
Secure the hydraulic accumulator. Position yourself during filling so that you cannot be
damaged by a possible leak or rupture of the filling.
Especially not in the longitudinal axis in front of or behind of the hydraulic accumulator.
Always use a fill and control set and please observe it valid instructions.
It is suitable for checking, filling and draining.
HENNLICH
supplies the control set as an
accessory.
Danger:
The nitrogen pressure varies according to the operating or ambient temperature.
Too rapid filling causes a rapidly pressure increase. Therefore observe this circumstance during
the filling process.
Before the testing, the hydraulic accumulator must be relieved on the fluid side.
After filling or after the release process, the temperature compensation must be done in the
hydraulic accumulator, before the checking of the pre-charge pressure.
The maximum precharging pressure must not exceed the maximum operating pressure of the
hydraulic accumulator.
Design limitations of the maximum pre-charge pressure must be observed. Check the fill valve
for leaks (for example, forming with foaming agents). Always use the protective caps to protect
the fill valve.
