. MAINTENANCE
Usually
SC
blowers and exhausters do not require maintenance. Wearing parts service life (bearings and
filters) depends on operating conditions. All machines have pre-lubricated bearing with a minimum service
life of 12.000 hours.
Nevertheless, it is necessary that qualified personnel periodically check the machine in order to avoid
possible failures.
CAUTION
All maintenance activities must be carried out by authorized and specialized personnel wearing personal
safety equipment.
During usual operation (fluid inlet and ambient temperatures not exceeding 40°C, differential pressure as
per nameplate data), the following routine maintenance activities have to be foreseen.
14.1 CLEANING
Make sure that the machine is shut down and locked against inadvertent start-up.
Clean the external part of the machine with compressed air. Deposit of dust on external blower surface
avoid an adequate thermal exchange and can cause an overheating of the interior.
Clean the ventilation grid of the motor fan cover. Dirt on motor fan cover reduces the air flow and causes
motor overheating.
Every 10/15 days during operation it is advisable to clean the filter cartridge. If the machine operate in a
high dusty environment it is necessary to replace it frequently. A dirt cartridge increases the pressure
differential, the absorbed power and the operating temperature.
If the machine doesn’t produce
any differential pressure, or too low pressure, or gas flow decreases, it is
necessary to clean the inside of the machine.
Dirt inside the machines can cause:
-
Change of running performances
-
Cloging due to clearance
-
Rotor displacement
-
Excessive vibrations
If it is necessary to clean the machine inside, follow the instructions here below:
-
Loosen the screws (13) and remove washers (14) and o-rings (15)
-
Loosen the screw (21) and remove the base (04)
