Bore Alignment of bearing pockets, seals, diaphragms
are time consuming tasks in the overhaul of turbines, engines and
compressors.
Now a new laser optical method replaces piano
wires, micrometers and optical instruments, reducing the alignment
time to a fraction. CENTRALIGN® uses a visible-laser
emitter and intelligent sensor to determine the centerline position
of bearing pockets with micron accuracy, even over separations of
up to 40m (130 ft.). All readings are transmitted via cordless infrared
link to a computer which automatically plots an alignment diagram
of all measurement points along with their offsets from the laser
reference line. The reference may be shifted to any desired position
in the display so that the offsets are automatically recalculated;
the laser eliminates troublesome pre-leveling and sag compensation.
CENTRALIGN® even allows the user to
follow corrections in the display as they are carried out. One or
two bore locations may be "fixed" to determine centerline
position and the special industrial computer can accommodate offsets
due to shaft sag, machine catenary, oil film or thermal growth.
