Troubleshooting

SYMPTOM

PROBABLE CAUSE

REMEDIES

Excessive
blower
temperature

Too much or too little
oil in gear reservoir

Check oil level.

See Lubrication on page 15

Too low operating
speed

Increase blower speed within limits.

Clogged

lter or

silencer

Remove cause of obstruction.

Excessive pressure
differential

Reduce pressure differential across the blower.

Elevated inlet
temperature

Reduce inlet temperature.

Worn lobe clearances

Check for proper clearances.

See Assembly Clearances on

page 40

Rotor end or tip
drag

Insuf

cient assembled

clearances

Correct clearances.

See Assembly Clearances on page 40

Case or frame
distortion

Check mounting and pipe strain.

Excessive operating
pressure

Reduce pressure differential.

Excessive operating
temperature

Reduce pressure differential or reduce inlet temperature.

Vibration

Belt or coupling
misalignment

Check carefully. Re-align if necessary.

Lobes rubbing

Check cylinder for hot spots, and then check for lobe contact at
these points. Correct clearances.

See Assembly Clearances

on page 40

Worn bearings or gears Check condition of gears and bearings. Replace if necessary.

Unbalanced or rubbing
lobes

Possible build-up on casing or lobes, or inside lobes. Remove
build-up and restore clearances.

Driver or blower loose

Check mounting and tighten if necessary.

Piping resonance

Check pipe supports, check resonance of nearby equipment,
and check foundation.
