2.8.4
Non-return valves
Non-return valves are installed in the outputs of the distribution block to prevent lubricant from
flowing back into the distribution block. All output ports to which primary lines are connected or
which are used to interconnect distribution blocks
must
be fitted with non-return valves. Output
ports which secondary grease lines are connected, must be fitted with non-return valves if
significantly different return pressures are expected at different output ports.
2.8.5
Failure of one of the doser segments
If one of the doser segments fails to operate properly (due to internal or external damage), the
whole greasing system will fail to operate.
2.8.6
Closing outputs
An output may only be closed-off after removal of the little plug that seperates the two outputs of
a doser segment. Removing the plug allows the grease meant for the close-off to exit through the
output that remains open (it doubles the output of the one that remains open). The distribution
block will become inoperable if the little plug is not removed.
2.8.7
Combining outputs
The outputs of a distribution block can be combined by installing an external interconnection line.
The total grease output in that case is the sum of all outputs thus interconnected.
The two outputs of a doser segment can be combined by removing the little internal plug that
seperates the two outputs and closing-off one of the ports. This doubles the output of the port that
remains open.
Figure 2.7
Combining outputs
The values in the illustration represent the outputs of the ports in mm³ (0,001 cc) per complete cycle
of the distribution block. The amount supplied is determined by the diameter of the piston.
