Bosch Rexroth AG
, Type HAD...-1X/ and HAD...-2X/, RE 50150-B/10.20
CAUTION!
High surface temperature during filling of the diaphragm type
accumulator with gas!
Risk of burning!
▶
Only touch the surfaces of the diaphragm type accumulator with heat-resistant
protective clothing, e.g. gloves, or do not work at hot surfaces.
▶
Allow the diaphragm type accumulator to cool down sufficiently before
touching it.
▶
Observe the protective measures of the system manufacturer.
▶
The prescribed pre-filling pressure is indicated in the hydraulic circuit diagram.
▶
Slowly open the shut-off cock of the gas bottle to make sure that the diaphragm
evenly touches the interior wall.
▶
Loosen the gas filling screw via the charging and test valve until gas can flow into
the accumulator.
▶
Charge the diaphragm type accumulator until the prescribed pre-filling pressure
is indicated on the pressure gauge of the prefill valve. Always keep an eye on the
pressure gauge during the charging process.
▶
Close the shut-off cock of the gas bottle.
▶
The gas filling pressure is temperature-dependent. During the charging, the
diaphragm type accumulator heats up. Wait until the diaphragm type accumulator
has cooled down.
▶
Check the pre-filling pressure and correct it if necessary.
▶
Remove the charging and test valve.
▶
Screw the protective cap back on the accumulator.
▶
Mark the set pre-filling pressure visibly on the diaphragm type accumulator.
In this connection, do not use stamps, punch presses or other mechanical
markings. We recommend using a sticker, e.g. warning sign for the diaphragm
type accumulator with material number R901441614, see also data sheet 50150.
The pre-filling pressure is now checked and set.
▶
Commission the diaphragm type accumulator with the overall system according
to the operating instructions of the overall system.
8.3 Re-commissioning after standstill
▶
Check whether the pre-filling pressure corresponds to the value p
0
indicated in
the circuit diagram. For this, proceed as described in chapter 10.1 "Maintenance".
▶
Check the gas port for leak-tightness.
▶
Make sure that the accumulator does not show any signs of corrosion and that
the coating is intact.
▶
Commission the diaphragm type accumulator with the overall system according to
the operating instructions of the overall system.
▶
Check the oil port for leak-tightness.
