Section 7 – Routine Maintenance
Inspection
Frequency will vary as widely as there are operating conditions. In
general proceed as follows:
Daily – Check unit differential pressure.
Weekly – Check pulse timer board and solenoid valves for function.
This usually is only listening to check uniform time in intervals between
blasts.
Monthly – Lubricate fan, rotary valve and screw conveyor. Check seals
on latter two for dust loss.
Quarterly – On Top Access Units, check for dust accumulation in clean
air plenum.
Repairs
Filter bags – Generally replacement, although some applications can be
laundered.
Solenoid Valves – Repair kits are available if a valve is stuck open or
fails to operate.
Diaphragm Valves – Repair kits are available if a valve is stuck open or
fails to operate due to a ruptured diaphragm.
Rotary Valves – Usually a matter of periodic seal and blade
replacement. More detailed information is supplied with the valve.
Screw Conveyors – Periodic replacement of “V” belts and shaft seals.
Inspect hanger bearings during filter bag change. Failure will be
detected by the squeal.
Fans – “V” belt tension and replacement of bearings if running rough.
Make sure rotor balance is maintained.
