Type HAD...-1X/ and HAD...-2X/, RE 50150-B/10.20,
Bosch Rexroth AG
9 Operation
WARNING
Bursting of the diaphragm type accumulator due to stability reduction caused by
extreme ambient temperature!
Danger to life! Explosion hazard! Damage to property!
▶
Make sure that the ambient temperature of the diaphragm type accumulator
does not exceed or fall below the ambient temperature indicated in
data sheet 50150.
▶
Observe the operating temperature and consider the ambient temperature.
Reduction of wall thickness of the pressure container when operated using
corrosive hydraulic fluids!
Danger of bursting! Damage to property!
▶
Only use the hydraulic fluids recommended in data sheet 50150.
WARNING
Bursting of the diaphragm type accumulator due to exceedance of the admissible
gas filling pressure!
Danger to life! Risk of injury! Damage to property!
▶
Observe the gas filling pressure indicated.
Bursting of the diaphragm type accumulator due to insufficient wall thickness
caused by corrosion!
Danger to life! Risk of injury! Damage to property!
▶
Check the diaphragm type accumulator for external corrosion
regularly – depending on the application.
▶
Determine the frequency of the corrosion checks according to the application.
▶
Check which provisions or ordinances are to be complied with in your country
and/or for your application.
During operation of the diaphragm type accumulator, observe the following points:
▶
Make sure that the embossing is always present and legible. Otherwise, further
operation is not allowed.
▶
Make sure that no loads/forces, e.g. temperature expansions or vibrations, occur
and are transferred to the diaphragm type accumulator.
The effects of external forces may lead to damage of the oil port and the
uncontrolled release of pressurized hydraulic fluid.
▶
Ensure that the diaphragm type accumulator is only operated within the
performance limits specified in data sheet 50150, in particular regarding gas
filling pressure, admissible operating temperature and maximum operating
pressure according to the embossing on the accumulator.
▶
Make sure that the diaphragm type accumulator is only operated in impeccable
condition.
▶
In case of emergency, an error, or in case of other irregularities, switch off the
system and secure it against restarting.
