 COMPRESSOR
ROD DROP INDICATOR
The
Exline Compressor Rod Drop Indicator is installed directly
beneath the compressor rod to detect wear.
If wear occurs
on the piston, piston riders, or cylinders, the compressor
rod drops and makes contact with the indicator. This contact
creates a friction temperature which melts the fuse-metal
plug in the device. A pressure drop in the pneumatic control
system results. This pressure drop can be used to shut
down the equipment or sound an alarm. A flat end indicator
can be used to detect excessive end play in rotating equipment.

Details
of Installation
Compressor
Rod Drop Indicator:
Using the packing case nuts as mounting points, a bracket
can be fabricated to support the CRD directly under
the compressor rod. Two holes are drilled and tapped
in the surface of the bracket to attach the device.
A shim stock (for example .010) is inserted between
the surface of the compressor rod and curved surface
of the device. The device is positioned firmly against
the shim stock and bolts are tightened. This permanently
positions the CRD in place. The shim is removed and
the device is piped to the control header. The flat
end device can be used to detect excessive end play
in rotating equipment.
Vented Compressor Rod Drop Indicator:
Install as described above. Tube supply “SUP”
side to air header. Tube vent side “VENT”
to atmosphere or appropriate area.
*Not recommended for use with units that operate with synthetic oils.
