Fig 6. Maximum Limit of Piston (4) Travel (Red Ring Showing)
If the work (e.g. a sample in a die set) is compressing to the extent that
the piston (
4
) has travelled to show the red line but the compression
load has not been reached, release the pressure by turning the
pressure release handle (
30
) anticlockwise (
slowly
) by about one
complete rotation. This will allow the piston (
4
) to return to rest. The
work will sink down with retraction of the piston (
4
) and a gap will be
created between the work and the top bolster pressing face (
23
). Turn
the lead screw handle (
20
) clockwise to bring the top bolster pressing
face onto the work again, and reapply the load from the piston (
4
) -
retighten the release handle (
30
) and pump via pump handle (
33
).
Note:
This procedure should be followed with samples that are highly
compacted when compressed within an evacuable pellet die.
When the required load is indicated on the load gauge (
31
), stop
pumping. The pressure and applied tonnage load against the work will
be held for as long as required. You may observe a slight decrease in
the pressure applied, indicated at the load gauge (
31
), as the work
(sample) being pressed may relax over time. You can bring the
pressure back up to the required load if desired by pulling gently on the
pump handle grip (
33
) again.
