Driver Location -- To properly balance the air load
stress on the blower drive shaft, locate the driver on the
inlet side for a vertical mounted blower and on the shaft
side for a horizontal mounted blower.
Belt Drive Alignment -- Belt drives must be carefully
aligned, with the motor and blower sheaves parallel to
each other and in the same plane. Belt tension should
be carefully adjusted according to the belt manufac-
turer’s recommendations using a Tension Tester.
Overtightening belts produces heavy
bearing loads and leads to unwarrant-
able premature failure.
On direct drive blowers, align the couplings so that the
offset and angular misalignment does not exceed .003”
total indicator reading (TIR). Lubricate coupling
according to manufacturer’s specification. With factory
installed drives, proper alignment has been established
before shipment. During shipping, handling and instal-
lation, it is likely that the alignment has been disturbed
and final adjustment must be made before start--up.
PIPING
All 30 Series DuroFlow blowers have female threaded
inlet and discharge connections. The connections are
large enough to handle maximum volume with
minimum friction loss. Reducing the pipe diameter on
either inlet or discharge will create unwanted
restrictions that increase the overall pressure differen-
tial and discharge temperature of the blower.
The 70 Series DuroFlow blowers have flat face inlet
and discharge flanges with ANSI 125 lb. bolt patterns.
When installing the blower, avoid subjecting the inlet
and discharge connections to strains caused by
misalignment of the connecting pipes. Never allow the
blower to carry the weight of the pipe.
Piping strain and misalignment stress will distort the
blower during operation, resulting in loss of critical
internal clearances. Loss of internal clearances will
result in serious machine damage and premature,
unwarrantable blower failure.
Whenever possible, install a spool or sleeve--type
expansion joint between the blower and the piping.
Where a flexible connection is not possible, the weight
of the rigid connection and piping must be separately
supported, and thermal pipe growth must be accom-
modated.
Thoroughly clean all system piping
internally before connecting to the
blower.
