4.7 General information about laying of
lubrication line
The following information should be observed for
the laying of the main lubrication lines and lubri-
cating point lines in order to ensure that the entire
centralized lubrication system works smoothly.
The main lubrication line should be dimensioned in
accordance with the maximum pressure and
conveyance volume to which the lubrication unit is
exposed. Where possible, the main lubrication line
should climb from the lubrication unit and enable
deaeration at the highest point of the lubrication
line system.
Lubricant distributors at the end of the main
lubricant line should be mounted so that the dis-
tributor outlets point upwards. If lubricant dis-
tributors have to be positioned below the main
lubricant line for system design reasons, they
should not be so placed at the end of the main
lubrication line.
The pipes, hoses, cut-off valves, control valves,
fittings, and so on must be suitable for the maxi-
mum operating pressure of the lubrication unit, the
permitted temperatures, and the lubricants to be
conveyed. In addition, the lubrication system must
be protected against excessively high pressure by
means of a pressure relief valve.
All components of the lubrication line system -
including pipes, hoses, cut-off valves, control
valves, fittings, and so on - must be carefully
cleaned before installation. No seals on lubrication
line systems 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 must be laid in a way that pre-
vents air pockets from forming anywhere on the
system. Cross section changes to the lubrication
line from a small to a large cross section in the di-
rection of flow of the lubricant are to be avoided.
Transitions from one cross section to another
should be smooth.
The flow of the lubricant in the lubrication lines
should not be impeded through the incorporation
of sharp bends, corner valves, or check valves.
Unavoidable cross section changes in lubrication
lines must have smooth transitions. Wherever
possible, sudden changes of direction are to be
avoided.
Caution!
Lubrication lines must be leak-tight. Lu-
bricants can contaminate the ground
and watercourses. Lubricants must be
used and disposed of properly. Country
specific regulations and laws on the use
and disposal of lubricants must be ob-
served.
Danger!
Centralized lubrication systems must be
leak-tight. Leaking centralized lubrica-
tion systems are a source of danger in
relation to slip hazard and the risk of
injury. When making installation,
maintenance, and repair work test the
centralized lubrication system for leaks.
Leaky parts of the centralized lubrication
system or components of the lubrication
equipment have to be sealed immedi-
ately.
Leaking centralized lubrication systems or compo-
nents of the lubrication equipment are a source of
danger in relation to slip hazard and the risk of
injury.
These dangers can cause physical injury to persons
or damage to other material assets.
Lubricants are hazardous substance.
Refer to safety precautions in the lubri-
cant manufacturer's material safety
data sheet.
You can ask the manufacturer of the lubricant for
the material safety data sheet.
