Blower Engineering Instructional Manual
7.0 Troubleshooting
Cause
Remedies
7.1
Inlet pressure different from the design value
Inlet piping is clogged
Check piping and remove obstruction
Rotation speed is not the same as design RPM
Check rotation speed and reset to design RPM
7.2
Outlet pressure different from the rated value
Outlet piping is clogged
Check piping and remove obstruction
Rotation speed is not the design RPM
Check rotation speed and reset to design RPM
7.3
Outlet temperature different from the rated value (stop the blower immediately)
Inlet temperature different from design value
Check inlet temperature and reset to rated value
Compression ratio is not the same as the
Check inlet and outlet pressures and reset to
design conditions
rated values
Rotors are worn
Measure clearances of rotors
7.4
Power absorbed different from the rated value
Differential pressure different from rated value
Check the inlet and outlet pressure and reset to
rated value
Speed of rotation is not the same as rated value
Check the speed of rotation and reset to
rated value
Incorrect electrical connection
Check electrical system
Rotors making contact
Stop blower immediately (see paragraph 7.3)
7.5
Loss of oil
Drive shaft seal is worn
Replace the drive shaft seal
Oil drain and level plugs gaskets are worn
Replace the gaskets
Oil level sight glasses are broken
Replace sight glasses, fill with oil
7.6
High oil temperature
Oil level too high
Reset correct oil level (see paragraph 6.1.1)
Oil too viscous
Use less viscous oil
High differential pressure
See paragraph 7.2
Oil produces foam
Change the type of oil
7.7
Unusual noises and/or vibrations (stop the blower immediately)
Differential pressure exceeds rated value
Check inlet and outlet pressures and reset to
rated values
Discharge temperature exceeds rated value
see paragraph 7.3
Rotors making contact
Stop blower immediately, measure gear and
rotor clearances
Scale on internal parts
Thoroughly clean the rotors and compression
chamber
Bearings are worn
Measure bearing clearances and, if necessary,
replace them
Intake of foreign particles
Remove foreign particles, clean the inside of
the blower
