6.10 Lubrication line connection
<
CAUTION
Risk of slipping
Exercise caution when handling lubricants.
Immediately bind and remove any leaked
lubricants.
<
IMPORTANT NOTE
Tension-free connection
Connect the lubricant lines in such a way that no
forces are transferred to the product.
All components of the centralized lubrication system must be
designed for:
•
The maximum pressure that occurs
•
The permissible temperature range
•
The delivery volume and the lubricant to be supplied.
<
IMPORTANT NOTE
Overpressure
Secure the centralized lubrication system against
excessive pressure using an appropriate pressure
relief valve.
Observe the following mounting instructions for safe and
trouble-free operation:
•
Use only clean components.
•
The flow of lubricant should not be impeded by the mounting
of sharp bends, angle valves, flap valves, seals protruding
inward, or changes in cross-section (large to small).
Unavoidable changes in the cross-section in lubrication lines
must have smooth transitions.
•
Use only grounded steel pipes.
