Implementation
▶ Check the running, flow and operating noise of the
hydraulic system and the components.
▶ Check for uncontrolled local vibrations.
▶ Check for the specified pressure range, damage and
leakage.
▶ Check the hose lines for leakage and inflection.
▶ Replace the hose lines at regular intervals according to
manufacturer's specifications, see EN 289, par. 7.2.6.
▶ Check the pipelines for leakage and corrosion.
▶ As a precaution, replace the seals at reasonable
time intervals.
1)
1)
The seals of attached and mounted valves are subject to a natural process of wear and
aging. Bosch Rexroth recommends replacement at appropriate time intervals. The intervals
are mainly determined by the operating conditions such as temperature and the cleanliness
of the hydraulic fluid.
10.4 Maintenance
Maintenance on the press module must be carried out in connection with the
overall machine/system.
▶ For the scope and time intervals of maintenance of the overall machine/system,
please refer to the maintenance schedule of the machine manufacturer.
▶ Document mandatory or unscheduled maintenance in a meaningful way and
retain it for verification purposes.
Since seals are subject to a natural process of wear and aging, they must be
replaced as required. Oil stains between the base area of the valve and the manifold
block are the first signs.
Bosch Rexroth recommends replacing seals during maintenance.
The intervals for the replacement of wear parts must be defined by the machine
manufacturer.
