Check pressure limiting valve
m
If lubricant emerges at the pressure lim-
iting valve (a), this indicates a malfunc-
tion in the system.
The consumers are no longer adequate-
ly supplied with lubricant.
- Release all distribution lines (b)
leading from the distributor (c) to the
consumers in succession.
- If lubricant emerges from one of the
released distribution lines (b) under
pressure, search in this lubrication
circuit for the cause of the blockage
which has triggered the pressure
limiting valve.
- After rectifying the malfunction and
reconnecting all lines, again check
the pressure limiting valve (a) for lu-
bricant emergence.
- Check all connections and lines
for leaks.
Check the flow of lubricant
at the consumers
Each lubrication channel at the consum-
ers must be checked as regards clear-
ance.
A
A pair of oil brushes, which apply the lu-
bricant onto the drive chain, is located on
both sides of the conveyor belt.
- Check whether an oil film is applied
onto the chain when the central lubri-
cating system is running.
- Check all connections and lines
for leaks.
