Operation
Carry out initial operation under “no load”
conditions by opening all valves and venting the
discharge to atmosphere, if possible. Then, start
the motor briefly, listen for unusual noises, and
make sure the booster coasts freely to a stop. If
no problem appears, repeat this check and let the
motor run a little longer. If any questions exist,
investigate before proceeding further.
Assuming all tests are satisfactory, the booster will
now be ready for continuous full load operation.
During the first several days, check periodically to
make sure all conditions remain acceptable and
steady. These checks may be particularly important
if the booster is part of a process system where
conditions may vary. At the first opportunity, stop
the booster and clean or remove the inlet filter.
Also, recheck leveling, coupling alignment or belt
tension, and mountlng bolts for tightness.
START-UP CHECKLIST
Tuthill recommends that these start-up procedures
be followed in sequence and checked off ( ) in
the boxes provided in any of the following cases.
• During initial installation
• After any shutdown period
• After maintenance work has been performed
• After booster has been moved to a new location
DATES
CHECKED:
Check the unit for proper lubrication. Proper oil level is critical.
See Lubrication on
page 14
.
See Recommended Lubricants on page 33
for information on acceptable
lubricants for the product.
Check the V-belt drive for proper belt alignment and tension.
Carefully turn the rotors by hand to be certain they do not bind.
WARNING
!
Disconnect power. Make certain power is off and
locked out before touching any rotating element
of the booster, motor, or drive components.
“Bump” the unit with the motor to check rotation (counterclockwise when facing the shaft)
and to be certain it turns freely and smoothly.
Start the booster and operate it for 30 minutes at no load. During this time, feel the
cylinder for hot spots. If minor hot spots occur,
see Troubleshooting on page 29
.
Apply the load and observe the operation of the booster for 1 hour.
If minor malfunctions occur, discontinue operation and
