Troubleshooting a Plenum Pulse Dust Collector
Is there power in and out of timer? Yes / No
Is air pressure at pulse valves per manufacturer’s recommendation? Yes / No
Do solenoids and diaphragms operate properly? Yes / No
Is pulse duration at recommended setting? (0.1 sec) Yes / No
Are poppet valves sealing closed? Yes / No
Is cleaning interval at the lowest setting that will allow air manifold pressure to rebuild? Yes / No
Turn on power and/or repair timer
Check for leaking solenoids and pulse valves; check compressed air source and check differential pressure.
Repair solenoid or diaphragm and check differential pressure.
Change setting and check differential pressure
Adjust and/or repair poppet valves and check differential pressure
Change setting and check differential pressure
Did you pull a filter bag and run a permeability test to check for blinding? Yes
Is filter bag blinding? Yes / No
Analyze for cause of blinding and correct; Replace filters and check differential pressure.
Is air/cloth ratio less than 6:1 if pulse-jet, 4:1 if Plenum Pulse, or 3:1 if reverse air or shaker? Yes / No
Is material being continuously removed from hopper? Yes / No
Contact BPS for further recommendations.
If pulse-jet or plenum pulse, consider pleated media conversion. If reverse air or shaker, consider pulse-jet conversion or increasing collector size.
Remove material continuously and check differential pressure.
