TITLE(s): BLOWER AND COMPRESSOR ASSEMBLER (machinery mfg.)
Fits and aligns machined parts, such as bearings, diaphragms, impeller wheels, blower casings,
shafts, and gear cages to assemble compressors, blowers, and vacuum pumps, according to
drawings and specifications, using handtools, power drills, and portable gas heating equipment:
Scrapes bearings to fit shafts, using hand scraper, blue chalk, and abrasive paper. Screws and bolts
together mechanical parts, such as gears, vanes, needle bearings, and ring gear, to assemble gear
cage assembly, using wrenches and screwdrivers. Shrinks impeller wheel, sleeves, spacers, and
balance piston onto shaft to form spindle, using portable gas heating equipment. Caulks metal
sealing strips into seams of impeller wheels, sleeves, and balance piston to form seal between
impeller wheel and diaphragm, using hammer and caulking chisel. Lifts and positions spindle into
casing (cylinder) to align diaphragm to spindle and upper and lower blower casing, using lead
wires, micrometers, and calipers. Levels beams supporting bedplates over test pit, using transit,
master straightedge, and levels. Aligns and levels blower, induction gear, oil tank, and drive
unit on bedplate to mark mounting holes, using gauges, rules, punch, and scribes. Drills, taps, and
reams holes for mounting bolts, coupling guards, and dowel pins, using portable drill press.
Installs inlet and discharge piping to blower, using handtools, and attaches instruments, such as
barometers, thermometers, pressure gauges, thermocouples, and speed indicator to blower. Dismantles
unit from test pit and cleans and oils parts prior to shipment. Makes specified tests to determine
blower performance, using electrical test equipment, and records instrument readings. May be
designated according to equipment assembled as Compressor Assembler (machinery mfg.); Pump Assembler
