How the
GREASOMATIC works
The discharge duration of a lubricator of this type is dependent on
the rate at which it generates gas. This in turn is governed by the
degree of exposure of the galvanic element's gas generating cathode
to the electrolyte in the presence of the sacrificial anode. The
GREASOMATIC has a unique adjustable galvanic element. Before
activation this is held in the underside of the cap and is connected
to the control knob on the exterior of the unit. Turning the control
knob causes the element's inner casing to rotate against its
stationary outer casing. This in turn causes the rod shaped cathode
to protrude from its seating to the extent necessary to provide the
appropriate rate of gas generation for the discharge duration set on
the dial.
By rotating the control knob and its linked dial, the desired
discharge duration can be set against the arrow on the casing. A
choice of 1, 2, 3, 4, 6, 8 or 12 months duration is available. (These
apply at an ambient temperature of about +20°C and will vary if the
unit operates at abnormally high or low temperatures. Detailed
guidance on the durations to be expected at various temperatures is
given in the separate download: GREASOMATIC Technical Data.
After the
discharge duration has been set, the red locking pin is depressed to
secure the setting and release the control knob from the dial. The
knob is then rotated in a clockwise direction to inject the galvanic
element into the electrolyte and actuate the unit.
