Troubleshooting

Low Capacity

1

Blower Speed too low

Check belt drive for slippage; adjust if necessary.
Check speed and compare with performance chart.

2

Excessive Pressure

Check inlet vacuum and discharge pressure; ensure protection valves are correctly set and operational.

Check there are no obstructions in the pipeline:
Check piping, filter, relief valves, isolation valves and silencer the assure an open flow path

3

Obstruction in piping

Check piping, filter, relief valves, isolation valves and silencer the assure an open flow path

4

Excessive slip

Check internal clearances for excess wear.

Excessive Power Consumption

1

Blower speed too high

Check the blower speed and compare with performance chart

2

Pressure too high

Can be caused by excessive pressure or obstructions in the piping.

Excessive Pressure
Check inlet vacuum and discharge pressure; ensure protection valves are correctly set and operational.

Check there are no obstructions in the pipeline:
Check piping, filter, relief valves, isolation valves and silencer the assure an open flow path

3

Unbalanced or rubbing impellers

Inspect outer casing for hot spots.
Check drive alignment (couplings / belts)
Check internal clearances for contact marks: contact S and A Engineering Services for advice

Can also be caused by a build-up of foreign material
Clean off foreign material
Contact S and A Engineer for blower overhaul.

4

Blocked inlet filter

Clean or change filter
Contact S and A Engineering for replacement filter elements

Excessive Heating

1

Incorrect or inadequate lubrication

Confirm correct oil specification and restore correct lubrication levels at both the drive and non-drive end.

2

Excessive pressure

Check inlet vacuum and discharge pressure; ensure protection valves are correctly set and operational.

Check there are no obstructions in the pipeline:
Check piping, filter, relief valves, isolation valves and silencer the assure an open flow path

3

Drive misalignment

Check and realign

4

Blower speed too low

Check belt drive for slippage; adjust if necessary.
Check speed and compare with performance chart.

Vibration or Noisy Operation

1

Drive misalignment

Check and realign

2

Unbalanced or rubbing impellers

Inspect outer casing for hot spots.
Check drive alignment (couplings / belts)
Check internal clearances for contact marks: contact S and A Engineering Services for advice

Can also be caused by a build-up of foreign material
Clean off foreign material
Contact S and A Engineer for blower overhaul.

3

Worn bearings and gears

Replace worn bearings and gears
Contact S and A Engineering for blower repairs

4

Loose motor, blower or pipework

Check and retighten bolts where loose

Seized Blower

1

Pressure overload

Check inlet vacuum and discharge pressure; ensure protection valves are correctly set and operational.

Check there are no obstructions in the pipeline:
Check piping, filter, relief valves, isolation valves and silencer the assure an open flow path

2

Mis-alignment

Check and realign

3

Build-up of foreign material

Clean off foreign material
Contact S and A Engineer for blower overhaul.

Drive Shaft Breakage

1

Excessive of overhanding load

Change or repair unit, contact S and A Engineering for assistance.
Check drive pulley dimensions Realign and tension Change drive configuration

2

Contact with foreign object

Check drive guard positioning, correct and secure
Check for other objects contacting on blower shaft
