Trouble Shooting a Pulse-Jet Dust Collector
Is there power in and out of timer? Yes / No
Is manifold pressure at manufacturer’s recommended setting? Yes / No
Do solenoids and diaphragms operate properly? / No
Is pulse duration at recommended setting? (0.1 - .015 sec) Yes /
Is cleaning interval at the lowest setting that will allow air manifold pressure to rebuild? Yes / No
Is differential pressure reduced by stopping fan while pulsing? 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 of diaphragm and check differential pressure.
Change setting 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 /
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.
