Observe the following notes when routing the pressure and reservoir lines.
t
Lines and hoses must be installed without pre-charge pressure, so that no further
mechanical forces are applied during operation that will reduce the service life of
the axial piston unit and, if applicable, the entire machine/system.
t
Use suitable seals as sealing material.
t
Pressure line
– For the pressure lines, use only pipes, hoses and connecting elements rated for
the operating pressure range specified in data sheets 91606 (see Table 12 and
Table 13).
t
Drain line
– Always route the reservoir lines so that the housing is constantly filled with
hydraulic fluid and to ensure that no air gets through the shaft seal even during
extended standstill periods.
– The case pressure must not exceed the limit values listed for the axial piston unit
in the data sheet under any operating conditions.
– The reservoir line joint in the reservoir must always be below the minimum fluid
level under all conditions (see chapter 7.3 "Installation position" on page 27).
t
If the axial piston unit is equipped with installed screw fittings, these must not be
unscrewed. Screw the threaded plug of the fitting directly into the installed screw
fitting.
Axial piston units are employed in regions using the metric measuring system, in
regions using the Anglo-American (imperial) measuring system and in regions using
the Japanese measuring system (
JIS –
J
apan
I
ndustrial
S
tandard).
Moreover, various
kinds of seal are used.
The system of units, the
kind of seal
and the size of female thread and threaded
plugs (e.g. threaded plug) must all match.
Due to the limited options for visually detecting differences, there is a risk of
mix-ups.
WARNING!
Leaking or popped-out threaded plugs!
If a threaded plug which is of a different measurement system,
kind of seal
and size
with respect to the female thread is pressurized, the threaded plug may loosen itself
or even be ejected from the hole in a projectile-like manner. This can result in serious
injury and damage to equipment. Hydraulic fluid can be discharged from this leakage
point.
▶
Use the drawings (installation drawing) to determine the required threaded plug
for each fitting.
▶
Make certain that there are no mix-ups when installing fittings, mounting bolts
and threaded plugs.
▶
For all female threads, use a threaded plug from the same system of units and of
the correct size.
