TROUBLESHOOTING
12.1
Water Entrainment
Issue:
Excessive discharge of water in the exhaust may be due to the
following:
Fix:
Incorrect rotation (correct rotation is counter-clockwise, when
viewed form the drive end).
Incorrect size cone spray or auxiliary nozzles and incorrect spray
pattern (i.e. flat spray at 7 o’clock position viewed from the inlet and
parallel to blades and cone spray to be centered at wheel).
Inlet spray should just miss inlet perimeter as it passes into the
scroll.
Disturbances at inlet, such as elbows or branch entries, causing
unbalanced airflow or dust loading (see Section 2.3).
Bent blade tips and/or obstructions in impeller such as rags,
collected material buildup, etc.
•
Pluggage of drains.
Incorrect outlet piece location. The bottom of the outlet piece should
never be above the bottom of the RotoClone
®
scroll. Any gasketing
that has squeezed out should be removed.
Improper gasketing of water cone, or damage/wear of the water
cone.
•
Incorrect water pressure.
