SINGLE-LINE LUBRICATION SYSTEM WITH PISTON DISTRIBUTOR FOR OIL OR FLUID GREASE
INSTALLATION LAYOUT
When installing a central lubrication system, route the main lines
and distributors in such a way that any air in the system can
escape on its own via the lube points.
To do so, mount the distributors at appropriate places and at the
end of the installation in such a way that the connections to the
lube points point upward (Fig. 1).
The main lines from the pump to the distributors should, if
possible, be installed with a rising gradient.
If lines have to be routed to distributors at lower
locations, proceed in accordance with Fig. 2.
Check the main-line resistance values, especially in regard to the
relief routine, with very large systems, ones with a large number
of branches or when highly viscous lubricants are used.
Each distributor port may be connected to only one lube point!
Do not connect the secondary line (distributor outlet connection)
to the lube point until bubble-free lubricant emerges at the line
end after repeated actuation of the pump. NOTE: It might be
necessary to pre-fi ll long secondary lines with lubricant.
If a secondary line becomes blocked or broken, it will not effect
the remaining lube points in the system.
FUNCTION
A pump feeds the lubricant through the main line to the piston
distributors. From there it is directed to the lube points in precisely
metered quantities. This takes place in a time- or pulse-controlled
sequence.
PLANNING
1. Determine the type of drive to be used for the lube pump
(manual, electric, or pneumatic).
2. Select the lubricant. Then determine the pump unit and type
of distributors.
3. Determine the number of lube points and defi ne the amount
of lubricant required to meet the needs of each point.
Ascertain the total amount of lubricant needed per unit of
time or clock pulse. Then determine the reservoir size based
on total delivery volume and desired refi ll frequency.
CHOICE OF DISTRIBUTORS
Select the piston distributors on the basis of the
metered quantity and spatial constraints.
The ratio of the metered quantities in respect to each other should
be the same as the consumption of the individual lube points.
The total amount needed by the installation is then regulated by
the number of lube cycles per unit of time.
