Troubleshooting 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? Yes/ No

Is pulse duration at recommended setting? (0.1 - .015 sec) Yes / No

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.

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.
