Table 7: Fault table
Fault
Possible cause
Remedy
Initial gas tension
changes during operation
Leakage/gas valve leaks
▶
Perform a visual inspection.
▶
Perform a leak test with leak spray during final assembly.
Gas valve damaged
▶
Replace the accumulator.
▶
Always use the charging and test device according to
data sheet 50150 for filling with gas and draining.
Gas valve function impaired due to
contamination
▶
Screw the cover caps back on after using the charging
and test device.
System-related change of pressure
dependent on the temperature
Temperature-dependent changes to the gas filling pressure
cannot be avoided.
▶
The gas filling pressure must therefore be chosen in
accordance with the expected operating temperatures.
Reduction due to permeation
▶
Refill gas.
Cracks on the vessel
Application out of specification
▶
Stop the system immediately.
▶
Replace the diaphragm type accumulator.
The diaphragm type accumulator must not be put into
operation again, but must be disposed of, see chapter 12
"Disposal".
Operation outside the prescribed
temperature range
▶
Stop the system immediately.
▶
Replace the diaphragm type accumulator.
The diaphragm type accumulator must not be put into
operation again, but must be disposed of, see chapter 12
"Disposal".
▶
After commissioning, check the operating temperature.
Internal corrosion
Use of inappropriate hydraulic fluid
▶
Stop the system immediately.
▶
Replace the diaphragm type accumulator.
The diaphragm type accumulator must not be put into
operation again, but must be disposed of, see chapter 12
"Disposal".
▶
Use suitable hydraulic fluid.
Residual humidity in the vessel due to
inappropriate storage conditions
▶
Stop the system immediately.
▶
Replace the diaphragm type accumulator.
The diaphragm type accumulator must not be put into
operation again, but must be disposed of, see chapter 12
"Disposal".
▶
Observe the prescribed storage conditions.
