4.7 Lubrication line connection
The lubrication line must be connected to the
lubrication unit in such a way that no forces
can be transferred to the assembled lubrica-
tion unit (stress-free connection).
Warning!
lubrication line should be rated for
the maximum operating pressure
of the lubrication unit. If they are not,
the lubrication line system
needs to be protected from excessive
pressure by means of
a pressure-limiting valve.
For higher operating pressures up to 250 bar
as can occur especially in progressive central-
ized lubrication systems, SKF cutting-sleeve
screw unions conforming to DIN 2353 can be
used. If using fittings from other manufactur-
ers, pay careful attention to the assembly in-
structions and technical specifications provided
by the manufacturer.
4.8 Lubrication line arrangement
The pipes, tubes, shutoff valves and directional
control valves, fittings, etc. that will be used
must be designed for the maximum operating
pressure of the lubrication unit, the permis-
sible temperatures and the lubricants that will
be delivered. The lubrication line system also
needs to be protected from excessive pressure
by means of a pressure-limiting valve.
All components of the lubrication line system
such as pipes, tubes, shutoff valves, directional
control valves, fittings, etc. must be carefully
cleaned before assembly. No seals should point
inward in the lubrication line system, as this
could hinder lubricant flow and introduce con-
taminants into the lubrication line system.
Lubrication lines should always be arranged so
that air pockets cannot form anywhere. Avoid
changes in the cross-section of the lubrication
line from small to large cross-sections in the
direction of flow of the lubricant. When the
cross-section does change, the transition
should be gentle.
