6.10 Lubrication line arrangement
To ensure that the entire centralized lubrica-
tion system functions smoothly, observe the
following instructions when arranging the
lubrication lines:
The main lubricant line must be dimen-
sioned in accordance with the maximum
operating pressure occurring in the pump
unit used and the delivery volume of that
pump unit. If possible, the main lubricant
line should rise upward from the pump unit
and be ventable at the highest point on the
lubrication line system.
Metering devices at the end of the main
lubricant line must be installed such that the
outlets of the metering devices point up-
wards. If the system configuration requires
that the lubricant metering devices be ar-
ranged below the main lubricant line, they
should not be placed at the end of the main
lubricant line.
The pipes, hoses, shut-off valves, directional
control valves, fittings, etc. that will be used
must be designed for the maximum operat-
ing pressure of the pump 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 sys-
tem such as pipes, hoses, shut-off valves,
directional control valves, fittings, etc. must
be carefully cleaned before assembly. No
seals in the lubrication line system should
protrude inwards in a way that disrupts
the flow of the lubricant and could allow
contaminants to enter the lubrication line
system.
Lubrication lines should always be arranged
so that air inclusions cannot form anywhere.
Avoid changes in the cross-section of the
lubrication line from small to large cross-
sections in the flow direction of the lubri-
cant. When the cross-section does change,
the transition should be gentle.
The flow of lubricant in the lubrication lines
should not be impeded by the incorporation
of sharp bends, angle valves, or flap valves.
Unavoidable changes in the cross-section in
lubrication lines must have smooth transi-
tions. Sudden changes of direction should
be avoided if possible.
