3.7 Example of a circulating-
oil- lubrication system with flow limiter
of series SMBM-X
See Figure 8
Before start-up of the machine, the lubricant is heated inside
the oil supply unit (
1
).
The main delivery line (
2
) opens when the specified lubricant
temperature is reached.
The lubricant now flows through warm-up lines (
4
), which are
switched on by valves (
3
), and through the return line (
5
) back
to the oil supply unit (
1
).
Once the specified lubricant temperature has been reached
on the return line to the reservoir, the warm-up lines (
4
) are
closed by the valves (
3
).
The pump (
1
) now delivers the lubricant to the main pressure
line (
2
). From here it travels through the oil filters (
6
) to the flow
limiters (
7
) and then via downstream progressive metering
devices (
8
) or flow dividers (
9
) to the lubrication points as
needed.
Either signal transmitters (
10
), piston detectors or gear
wheel-type flow indicators with pulse sensors in connection
with monitoring devices (
11
) are used to monitor the individual
volumetric flows.
