INTERVENTION TABLE
The following table shows all required periodical operations to maintain side channel turbine efficiency.
HAZARD
Wear suitable protection equipment when carrying out maintenance work.
OPERATION TYPE
FREQUENCY
OPERATOR QUALIFICATION
Check intake filter
100 h
Replace intake filter
500 h
Clean the motor fan protection.
1000 h
General external cleaning of the turbine.
1000 h
Check that the vacuum and/or pressure reducing
valves are working
1000 h
Clean the intake and discharge silencers.
2000 h
Grease the bearings.
2000 h
Replace the bearings.
15000 ÷ 20000 h
More frequent maintenance may be necessary depending on the kind of use and environment where the turbine
is installed (high temperature of intake gases and/or workplace, presence of condensable vapours in the intake
gases, very dusty workplace, etc.).
6.2.1
INTAKE FILTER CONTROL
Check and if necessary clean off any solid residue particles on the intake filter cartridge and the internal surfaces
of the container.
Cleaning has to be done using a dry cloth for the container while, for the cartridge, blowing compressed air aimed
in the opposite direction to the conveyed flow's filtering direction (that is, from the inside outwards). Do not use
fluids or substances other than those indicated.
6.2.2
REPLACING THE INTAKE FILTER
Should the side channel turbine be used in environments with a high dust content, you will need to replace the
filter cartridge more regularly compared to what was previously indicated in the table.
6.2.3
CLEANING THE MOTOR FAN PROTECTION
Cleaning the motor fan protection is done in order to remove any dust. This must be done using a blow of
compressed air and a dry cloth. Do not use fluids or substances other than those indicated.
6.2.4
GENERAL EXTERNAL CLEANING OF THE TURBINE
General cleaning of the side channel turbine is done in order to remove any dust. This must be done using a blow
of compressed air and a dry cloth. Do not use fluids or substances other than those indicated.
6.2.5
CHECKING THE OPERATION OF VACUUM AND/OR PRESSURE REDUCING VALVES
Checking that the vacuum and/or pressure reducing valves are working must be done by closing the turbine's
intake and outlet. In this case the safety devices installed must start working and the electric motor absorption
must stay within the levels shown on its plate.
