8.1.6 Performing flushing cycle
In order toremove foreign particles from thesystem, BoschRexroth recommends
aflushing cycle for theentire system prior toinitial commissioning. To avoid internal
contamination, do not include theaxial piston unit inthe flushing cycle.
Use anadditional flushing unit toperform theflushing cycle. Follow
theinstructions oftheflushing unit's manufacturer for theexact procedure during
theflushing cycle.
8.2 Running-in phase
NOTICE
Property damage due toinsufficient viscosity!
Elevated hydraulic fluid temperature may excessively reduce viscosity and damage
theproduct!
▶ Monitor the operating temperature during the running-in phase,
e.g.bymeasuring the case leakage temperature.
▶ Reduce theloading (pressure, rotational speed) oftheaxial piston unit
ifunacceptable operating temperatures and/or viscosities occur.
▶ Excessively high operating temperatures indicate faults that have tobe analyzed
and eliminated.
The bearings and sliding surfaces are subject toarunning-in phase. The increased
friction atthestart oftherunning-in phase results inincreased heat development
which decreases over time. Volumetric and mechanical-hydraulic efficiency isalso
greater until therunning-in phase ofabout 10operating hours isconcluded.
To ensure contamination in the hydraulic system does not damage the axial piston
unit, the following procedure is recommended after the running-in phase:
▶ After therunning-in phase, have ahydraulic fluid sample analyzed for therequired
cleanliness level.
▶ Change thehydraulic fluid iftherequired cleanliness level isnot reached. If
alaboratory test is not carried out after the running-in phase, it is recommended
to change the hydraulic fluid.
