Interrupted Star position
Rotary valve
Start the rotary valve when the blower has reached
full speed. (The blower can also be delivered with
automatic start of the rotary valve).
The conveying capacity is regulated by means of the
intake shutter on the rotary valve. For blowers with
air intake regulator the biggest capacity is reached by
slowly opening the intake shutter of the rotary valve
until the indicator on the blower intake regulator is
about 10mm (3/8 in.) from the left stop. For blowers
without air intake regulator, maximum capacity can
only be achieved by trial and error.
Start
Conveying
Venturi
The venturi is self-regulating. It does not take in more
material than the blower can cope with. Where the
venturi is provided with an intake shutter, this must be
opened fully when the blower is started.
Stop:
Delta position
If possible, run the pipe system clean before stopping
the blower. The rotary valve must therefore either be
stopped before the blower or at the same time. Never
stop the blower before the rotary valve, as this can
cause the pipe system to block.
Even in cases where the piping system is not clean
when the blower is stopped, this normally will not
cause problems. It is therefore also possible to
keep the rotary valve/venturi in the same position
while starting and stopping the blower.
Service and maintenance:
Always stop the blower prior to repair and maintenance
and avoid unintentional start of the blower.
Retightening
On a new blower, all bolts and screws are to be
retightened after the first working day. Apart from that,
make sure that they are tight at all times.
Cleaning
Regularly check the surfaces of the blower and motor
for dust and other impurities. If the dust layer is more
than 0,5 mm (0,02") thick, it must be removed. It will
depend on the dust content in the blower surroundings,
how often it is necessary to check/clean the blower
and motor.
Greasing
Except from TRL 500, all bearings on all TRL blowers
have been greased from the factory and do not need
any further greasing.
TRL 500 only: Grease the bearings on the blower belt
side every 200 working hours. Use a lithium based
grease of minimum quality as Mobil Mobilux EP2 or
Esso Beacon EP2. Regrease with approx. 20 cm
gram (1.2 cub.in.) each time. Never over grease the
bearings. If the casing is filled with too much grease,
the bearings will get hot.
