documents.
12.15. Fan
12.15.1. General
- Warning: Air flow can lead moving of stationary
parts (even if fan is switched off).
- Warning: While working on the fan make sure
power is off.
- Type of the belt used, belt tension and number of
belts and their dimensions are indicated on the la-
bel attached to fan housing and ventilator cell door
together with information on pulley the belt is con-
nected on.
- Take care to insulation of terminal box when mak-
ing motor cable connections. No humidity should
enter into the box.
12.15.2. Bearings
Bearings of smaller fans are closed type and do not
require greasing. If larger fans that require greasing
is used, grease them every six months. For higher
temperatures and increased contamination greasing
intervals should be adjusted as required. For the type
of grease, observe fan manufacturer recommenda-
tions. For higher temperatures and a higher degree
of humidity use a lubricant recommended by the sup-
plier.
Electric motors are equipped with roller bearings, de-
pending on the motor size the bearings are lubricated
for complete life cycle or are equipped with a grease
nipple. The lubrication interval and type of lubricant
are as above.
12.15.3. Power transmission
After starting up the unit or after replacing the belts,
belt tension has to be checked within one week for
the first time and then after two weeks, and tension
should be re-adjusted, if required. After that, check
belt tension and inspect the condition of the belts
every three months.
CORRECT BELT TENSION depends on:
- type of belt,
- power to be transmitted,
- belt speed.
Belt tension is calculated for each transmission. If
belt tension is too high this can result in premature
wear at bearings and vibration. If it is too low this can
result in belt slippage and belt wear.
Sequence for installation of new belts:
- Make sure that the pulleys are correctly aligned. If
necessary, re-align.
- Position all belts loosely on the pulleys, do not pull
tensioned belts over pulleys.
- Tension belt, check their tension.
- Re-check alignment.
If fan speed changes or if a motor with different pow-
er specifications and/or speed is installed, the manu-
facturer must be informed and no further work should
be performed.
Alarko Carrier will calculate the load to be carried by
the fan and also bearing loads. Failure to perform this
step may lead irreparable damages at fan.
Alarko Carrier accepts no liability for any modifica-
tions done without approval. See chapter related with
safety.
