Piping Instructions
Note:
The poly-hose is designed
for clean-up only. For prolonged
operations of the blower use the
heavy duty flexible steel hoses and
pipes only.
Use only one poly-hose in the
suction line. More poly-hoses will
reduce the conveying capacity
considerably.
Avoid connecting the poly-hose
directly to the suction cyclone. This
puts too much stress on the hose
and may cause a sharp bend re-
ducing capacity.
3. Keep the pipeline as short as
possible. Do not use more
bends and diverters than
necessary. This provides opti-
mum capacity and the gentlest
conveying.
4. Always use the OK160 dimen-
sions for the entire pipe system.
Even a short piece of either
bigger or smaller diameter will
reduce conveying capacity con-
siderably.
5. Air leaks between pipes will
reduce conveying capacity. This
is more important on the suction
line than on the pressure line.
Therefore, take care to avoid
leaks on suction line. It should
be recommended to use the
sturdy OKR clamps on the suc-
tion side.
6. If possible, all pipes should run
either horizontally or vertically.
Sloping pipes reduce capacity
and increase pipe wear.
7. Pipelines can be suspended in
long free spans but do not allow
these to exceed 4 m outdoors
and 5 m indoors without sup-
port.
2. Suction from a hopper:
Use the short suction line of flexible
steel hose only. The highest capac-
ity is obtained if the intake nozzle is
placed as vertically as possible.
The capacity of the blower depends to
a large extent on the arrangement of
the pipe layaut.
The following points should be
observed:
1. Clean-up operations:
Connect the two flexible steel hoses
or a 45º bend and a steel hose to
suction cyclone and use the hoses
to bring the suction line uniformly
down to the ground. Then extend it
with rigid pipes and use the flexible
poly-hose just before the intake
nozzle.
