Troubleshooting the Dust Collector (continued)
Condensation
If moisture has been condensing inside the collector check the dew point
temperature of the incoming air stream. It may be necessary to insulate
the collector and/or the ductwork leading to the collector to keep surface
temperatures above the dew point and prevent condensation inside the
dust collector.
NOTE: Collectors that have blinded bags can possibly be put into
service by running the pulsing air system for 15 to 30 minutes with a 10
second “off time” and without the main fan or blower running. If the
pressure drop is not lower when the main fan is started again remove
the filter bags from the collector and replace. Make sure the timer “off
time” has been reset to specifications prior to re-start. Information
pertaining to filter bag cleaning may be obtained by calling your
CAMCORP sales representative.
Extremely Low Pressure Drop
Differential Pressure Gauge
Check the differential pressure gauge or manometer and the tubing
leading to the dust collector.
Holes in Filter Bags or Bags Incorrectly Installed
Inspect the filter bags for holes, rips, tears or excessive wear. Assure
that the filter bags were installed correctly according to the “Bag & Cage
Installation” section.
Ductwork and Dampers
Inspect the ductwork to and from the dust collector for air leaks or
blockage. Assure that any dampers in the system are correctly
positioned to allow for proper air flow through the dust collector.
Leaks in the Housing
Check the tube sheet (flat steel sheets from which the filter bags are
suspended) and the dust collector housing for holes, cracks or loose
gasketing that would permit air to bypass the dust collector or filter bags.
