STEP 3
Unloaded pump at longer intervals
• Run for a period at no load condition until system is stable and control is
established.
• Check fluid level in the tank.
• Filling up the system with fluid may be needed as parts of the system has been
filled up.
• Check for unusual noises or vibrations.
• Check for leakage points.
• Stop the electric motor and correct if any faults discovered on the points above.
• Check all connections, screws etc. and tighten if necessary.
• Restart when finished.
STEP 4
loaded hydraulic system
• The hydraulic system can be loaded when the hydraulic system functions works
satisfactorily in unloaded running condition.
• Gradually increase load until satisfactory operation is obtained.
• It may be necessary at this point to make adjustments to flow, ramp rates, etc.
• Cycle the system until normal operating temperature is reached.
• If system will run with speed feedback, check and adjust feedback regulator
parameters.
STEP 5
Check:
• Unusual noises or vibrations.
• Function of safety equipment.
• Temp in tank and hydraulic loop. Check also that the cooler control is stable.
• Leakage points.
STEP 6
After test
• Correct any faults discovered at the points above.
• Check the filter indicator. It might be necessary to change filter elements due
to particles from the piping. When changing filter elements carefully follow the
instructions in
to avoid dirt into the system. If there still is dirt in
the system, additional flushing is necessary in order to prevent premature failure of
system components.
• Check all connections, screws etc. and tighten if necessary.
