Troubleshooting
Symptom
Possible causes
Remedies
Blower motor
fails to start.
• Power absent
• Overload protection system in
operation
• Motor failure
• Turn on the power supply.
• Turn off the switch , determine the cause(s),
remove it (them) and restart.
• Inspect and repair the motor (Consult the
manufacturer).
Blower noise,
unusual
vibrations
• Broken motor bearings
• Foreign matter mixed
• Impeller out of balance
• Replace the bearings.
• Remove the foreign matter.
• Clean the impeller.
Correct the imbalance (Consult the manufacturer).
Blown dust
leakage
• Broken filter cloth.
• Filter cloth mounting error
• Packing worn off
• Dust particles too fine
• Replace the filter cloth.
• Remount the filter cloth.
• Replace the packing with a new one.
• Replace the filter cloth with a higher-performance
version.
Poor suction
power
• Damper closed
• Inlet piping clogged
• Filter cloth blinding
•
Using both side of suction port
• Open the damper.
• Clear deposit from the piping.
• See the following item.
•
Please make piping branch only on one side of
suction port and pipe it again.
Filter cloth
blinding
• Insufficient pulse pressure
• Pulse intervals too long
• Filter cloth’s life
• Adverse dust attributes
• Increase the pulse pressure (to max. 0.7 MPa).
• Shorten the pulse intervals.
• Replace the cloth with a new one.
• Effective measures should be taken separately.
•
Too much quantity of dust
•
Please install pretreatment device like cyclone,
sedimentation box etc.
•
Because of too high filtering speed,
dust enters into the meshes of
filters and cannot be removed by
dust removing system.
•
Control suction amount by using damper etc.
No pulse
available
• Power supply to the pulse generator
turned off
• Solenoid valve failed
• Solenoid valve wiring broken
• No compressed air supplied
•Pulse control board failure
• Turn on power supply to the pulse control board.
• Inspect the fuse.
• Replace the solenoid valve.
